Item 3.        Source and Amount of Funds or Other Consideration.

               Prospect Street NYC Discovery Fund, L.P. (the "Investor")
entered into that certain Senior Credit Agreement dated as of May 20, 1998 (the
"May Credit Agreement") by and among Skyline and each of its wholly-owned
subsidiaries (together, the "Co-Borrowers"), the Bank of New York, as Trustee
for the Employees Retirement Plan of Keyspan Energy Corp. ("Keyspan") and the
Investor, pursuant to which each of the Investor and Keyspan received Senior
Secured Promissory Notes (the "May Notes") issued to it by the Co-Borrowers in
the aggregate principal amount of $935,000 ($435,000 to the Investor) and a
Warrants to be issued to it by Skyline upon the earlier to occur of (x) the
prepayment of all or any portion of any May Note and (y) June 15, 1998 (the "May
Warrants") to purchase shares of Common Stock upon the occurrence or failure to
occur of certain events. In addition, on June 30, 1997 the Investor loaned to
Skyline $500,000 payable on demand at an interest rate of 14% per annum. The
funds used were obtained from the working capital of the Investor. In addition,
on April 23 and 25, 1997, June 19 and 20, 1997 and July 2 and 8, 1997, CFD
purchased an aggregate of 13,900 shares of Common Stock for a total
consideration of $49,216.33 (including brokerage fees and expenses). The funds
used to purchase such securities were obtained from the working capital of CFD.

Item 4.        Purposes of Transactions.

               On May 20, 1998 Skyline and its subsidiaries entered into the
May Credit Agreement with Keyspan and the Investor (the Investor together with
Keyspan, the "Institutional Investors") relating to the financing of an
aggregate of $935,000, of which $435,000 was funded by the Investor (the
"Financing") in exchange for the issuance to the Institutional Investors of the
May Notes and May Warrants, when issued. The May Notes mature on July 15, 1998
(the "Maturity Date"), accrue interest at a per annum rate equal to 14% and are
secured by (with certain exceptions) all the assets of Skyline and its
subsidiaries. The May Notes and the obligations under the May Credit Agreement
and May Warrants are also collateralized by a pledge of the stock of the
subsidiaries of Skyline. In connection with the May Credit Agreement, Keyspan
also received the right to appoint two members of Skyline's Board of Directors.
Further, as a result of the pending issuance of the May Warrants, Skyline has
determined that the conversion rate of the Series A Preferred Stock (the
"Preferred Stock") held by the Investor will be  adjusted from a conversion
rate of one share of Common Stock for each share of Preferred Stock to a
conversion rate of 6.91 shares of common stock for each share of Preferred
Stock.               

               In the event Skyline receives additional gross proceeds of at
least $3 million in an equity financing (an "Equity Financing") on or prior to
the Maturity Date, each $1.00 of principal amount of the May Notes may, at the
option of the holder, convert into $1.25 of the securities issued in such
Equity Financing. In the event the entire principal amount of the May Notes
(plus all accrued and unpaid interest thereon) is repaid prior to the Maturity
Date, then the May Warrants will be exercisable for an aggregate of 64% (after
issuance) of the fully diluted Common Stock of Skyline on the date of such
issuance at an exercise price of $0.375 per share (in which event the
conversion rate of the Preferred Stock will be readjusted to 4.80 shares of
Common Stock for each share of Preferred Stock). In the event the entire
principal amount of the May Notes has not been repaid (plus all accrued and
unpaid interest thereon) or converted (pursuant to the terms of the May Notes)
prior to the Maturity Date, then the May Warrants will be exercisable for an
aggregate of approximately 94% (after issuance) of the fully diluted Common
Stock of Skyline on the date of such issuance at an exercise price of $0.375
per share (approximately 173 million shares in the aggregate, of which
approximately 86.5 million would become issuable pursuant to the May Warrant
issued to the Investor). Upon consummation of an Equity Financing and repayment
or conversion of the entire principal amount of the May Notes (plus all accrued
and unpaid interest thereon) before the Maturity Date, the May Warrants will be
canceled and of no further force or effect (and the conversion rate of the
Preferred Stock would be readjusted back to one share of Common Stock for each
share of Preferred Stock). The May Warrants have a cashless exercise procedure.
Skyline has reported to the Investor that Skyline believes that the $935,000
cash infusion will enable it to resolve its short-term cash management problems
while attempting to raise necessary additional financing. Skyline has reported
to the Investor that Skyline is currently exploring ways in which to attempt to
consummate an Equity Financing, including possibly conducting a rights
offering. However, no assurances can be made that Skyline will be successful.
Skyline has reported to the Investor that if Skyline is unable to raise
additional capital in the near term, there will likely be a material adverse
effect on Skyline, possibly resulting in curtailment of certain operations.

               Skyline has reported to the Investor that Skyline is in the
process of applying to the Nasdaq Stock Market, Inc. (the "Nasdaq") to obtain a
waiver of the shareholder approval requirement under Nasdaq rules relating to
the possible issuance of 20% or more of the outstanding common stock of Skyline
as a result of the possible exercise of May Warrants to be issued in connection
with the Financing. In the event such waiver is not granted by Nasdaq,
Skyline's securities may be delisted from the Nasdaq Small Cap Market. Skyline
has also informed the Investor that as a result of failure to comply with the
Nasdaq maintenance criteria of a minimum bid price of $1.00 for Skyline's
Common Stock, Skyline's Common Stock may de delisted from the Nasdaq Small Cap
Market. Skyline expects to receive further instructions from Nasdaq on June 1,
1998. However, according to Nasdaq, failure to comply with these minimum bid
criteria by June 11, 1998 is likely to result in a delisting.
<PAGE>   10
               In connection with the Financing, Zalman Silber, President and
Chief Executive Officer, agreed to relinquish all positions in Skyline held by
him and to deliver to Skyline for cancellation all of his options and warrants
in Skyline in exchange for the forgiveness of amounts previously agreed to be
refunded by Mr. Silber to Skyline in the amount of $750,000 and payment by
Skyline to Mr. Silber of $206,250 and to transfer to the Investor all of his
960,000 shares of Class A Common Stock (670,000 shares of which will likely be
forfeited to Skyline on June 30, 1998 pursuant to existing escrow arrangements)
in consideration for an aggregate of $100 and the financing by the Investor.
Skyline and Mr. Silber also exchanged general releases. Mr. Silber has granted
an irrevocable proxy with respect to the vote of such Class A Common Stock to
the Investor until the remaining 290,000 shares of Class A Common Stock, which
are currently pledged as collateral in connection with a loan, can be
transferred upon release of the pledge. Mr. Silber has also agreed not to
compete with Skyline in New York City for a period of ten years. The Investor
has been informed that Steven Schwartz, Skyline's Chief Financial Officer, will
assume a portion of the responsibilities of the Office of the Chief Executive
Officer on an interim basis and has been designated as the Executive Director
of Operations and Finance and that Skyline is in the process of hiring an
Executive Director of Marketing and Business Development, who will also assume
a portion of the responsibilities of the Office of the Chief Executive. Mr.
Silber will retain the title of Chairman of Skyline's Advisory Board. On or
about March 13, 1998, the Investor, as holder of the Series A Preferred Stock,
designated Thomas Riordan to replace Ronald D. Celmer on Skyline's Board of
Directors. Mr. Celmar is no longer affiliated with the Reporting Persons.

Item 5.        Interest in Securities of the Issuer.

               (a) The aggregate number of shares of Common Stock beneficially
owned by the Investor and the General Partner as of May 20, 1998 is 94,152,524
shares (up to 7,538,181 of which shares the Investor has a right to acquire
upon conversion of the Series A Preferred Stock, 146,341 of which the Investor
has a right to acquire upon exercise of the Warrants and up to 10,800,000 of
which the Investor has the right to acquire upon exercise of the May Warrants
upon the occurrence or failure to occur of certain events described previously),
or approximately 98.5 percent of the Common Stock, in each case, not including
the shares of Common Stock or Class A Common, or other securities owned by
Zalman Silber, former President of Skyline, with respect to which shares the
Investor was granted a proxy with respect to certain matters and the holder
(including certain successors) is required to vote for certain matters and not
including any securities owned by Connecticut Financial Developments, L.P. or
Prospect Street NYC Co-Investment Fund, L.P., with which the Investor may be
deemed to be acting as a group. In addition, the Investor was granted a proxy by
Mr. Silber good until March 15, 1999 to vote all shares of capital stock of Mr.
Silber with respect to all matters and such shares are not included in the
aggregate number of shares of Common Stock beneficially owned by the Investor.
As reported to the Reporting Persons by Skyline, as of May 20, 1998, there were
960,000 shares of Class A Common owned by Zalman Silber and Mr. Silber had no
options or warrants to purchase securities of the Issuer. The aggregate number
of shares of Common Stock beneficially owned by CFD and CFDGP as of May 20, 1998
is 66,600, or approximately 4.80 percent of the Common Stock, in each case, not
including any securities owned by Prospect Street NYC Discovery Fund, L.P. or
Prospect Street NYC Co-Investment Fund, L.P., with which CFD may be deemed to be
acting as a group. The aggregate number of shares of Common Stock beneficially
owned by Prospect II and Prospect II GP as of May 20, 1998 is 43,902, or
approximately 3.07 percent of the Common Stock, in each case, not including any
securities owned by Prospect Street NYC Discovery Fund, L.P. or Connecticut
Financial Developments, L.P., with which Prospect II may be deemed to be acting
as a group. As disclosed in Skyline's proxy statement for its annual meeting of
shareholders held on November 26, 1997, non-employee directors automatically
receive stock options to purchase 5,000 shares of Common Stock on their election
or reelection to the board of directors of Skyline. To date, Messr. Barry, a
director of Skyline, was granted options to purchase 15,000 shares of Common
Stock (which shares are not included in the beneficial ownership reported by the
Investor, the General Partner, CFD, CFDGP, Prospect II or Prospect II GP). The
Reporting Persons may be deemed to be acting as a group with respect to
securities of Skyline.

               (b) The responses of the Reporting Persons to Items (7) through
(11) of the portions of pages 2 through 7 hereto which relate to shares of
Common Stock beneficially owned are herein incorporated by reference.

               (c) Information concerning the transactions in Common Stock by
CFD on April 23 and 25, 1997, June 19 and 20, 1997 and July 2 and 8, 1997 is set
forth on Annex A. Other than as reported in this Statement, none of the
Reporting Persons nor, to the best of their knowledge, any of the persons named
in Schedule A hereto has effected a transaction in shares of Common Stock during
the past 60 days.

               (d) No person other than the Reporting Persons has the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of the securities to which this Statement relates.
<PAGE>   11
               (e)  Not Applicable.


Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
the Securities of the Issuer.

               Except as set forth in this Statement, to the best knowledge of
the Reporting Persons, no contracts, arrangements, understandings or
relationships (legal or otherwise) exist among the Reporting Persons and the
persons listed on Schedule A hereto or between such persons and any other person
with respect to any securities of Skyline, including but not limited to transfer
or voting of any such securities, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, divisions of profits or
loss, or the giving or withholding of proxies.

except solely by reason of any act or omission of either of the Lenders, or any
Co-Borrower, shall so state in writing; or

                  7.9 Change of Control. A Change of Control shall occur.

                  THEN, (i) upon the occurrence of any Event of Default
described in the foregoing Sections 7.5 or 7.6, the unpaid principal amount of
and accrued interest on the Loan shall automatically become immediately due and
payable, without presentment, demand, protest or other requirements of any kind,
all of which are hereby expressly waived by the Co-Borrowers, and the
obligations of each of the Lenders hereunder shall thereupon terminate; and (ii)
upon the occurrence of any other Event of Default, either of the Lenders may, at
any time by written notice to the Co-Borrowers, declare the Loan to be, and the

                  8.2   Indemnity.


                  (a) Agreement to Indemnify. The Co-Borrowers (as
"Indemnitors") agrees to indemnify each of the Lenders, each holder of any Loan,
Notes or Warrants, and any stockholder, member, general partner, limited
partner, officer, director, manager, agent and Affiliate of either of the
Lenders or holder (collectively called the "Indemnitees"), in respect of, and
hold them harmless from and against, any and all Losses suffered, incurred or
sustained by any of them or to which any of them becomes subject, in any manner
arising out of or relating to any breach of any representation or warranty of
the Co-Borrowers contained in this Agreement or any Operative Agreement (the
"Indemnified Liabilities").

                  (b) Notice of Claim. Each Indemnitee shall give the
Indemnitors prompt written notice of any claim that might give rise to
Indemnified Liabilities setting forth a description of those elements of such
claim of which such Indemnitee has knowledge; provided, however, that any
failure to give such notice shall not affect the obligations of the Indemnitors
unless (and then solely to the extent) the ability of the Indemnitors to provide
such indemnification is prejudiced thereby.
<PAGE>   22
                  (c) Control of Defense. The Indemnitors shall have the right
at any time during which such claim is pending to select counsel to defend and
control the defense thereof and settle any claims for which they are responsible
for indemnification hereunder (provided that no Indemnitor will settle any such
claim without (i) the appropriate Indemnitee's prior written consent which
consent shall not be unreasonably withheld or (ii) obtaining an unconditional
release of the appropriate Indemnitee from all claims arising out of or in any
way relating to the circumstances involving such claim) so long as in any such
event, the Indemnitors shall have stated in a writing delivered to the
Indemnitee that, as between the Indemnitors and the Indemnitee, the Indemnitors
are responsible to the Indemnitee with respect to such claim to the extent and
subject to the limitations set forth herein; provided, however, that the
Indemnitors shall not be entitled to control the defense of any claim in the
event that in the reasonable opinion of counsel for the Indemnitee there are one
or more defenses available to the Indemnitee which are not available to the
Indemnitors; provided, further, that with respect to any claim as to which the
Indemnitee is controlling the defense, the Indemnitors will not be liable to any
Indemnitee for any settlement of any claim pursuant to this Section 8.2 that is
effected without its prior written consent. To the extent that the undertaking
to indemnify and hold harmless set forth in the preceding sentence may be
unenforceable because it is violative of any Law or public policy, each
Indemnitor shall contribute the maximum portion which it is permitted to pay and
satisfy under applicable Law, to the payment and satisfaction of all Indemnified
Liabilities incurred by the Indemnitee for any Indemnitor.

                  8.3 Entire Agreement. This Agreement and the Operative
Agreements supersede all prior discussions and agreements between the parties
with respect to the subject matter hereof and thereof and contain the sole and
entire agreement between the parties hereto with respect to the subject matter
hereof and thereof.

                  8.4   Purchase for Investment.


                  (a) The Lenders hereby represent and warrant to the
                  Co-Borrowers that:

                  (i) the Notes will be acquired by the Lenders for their own
                  account for the purpose of investment and not with a view to
                  the resale or distribution of all or any part of the Notes in
                  violation of the Securities Act, it being understood that the
                  right to dispose of the Notes shall be entirely within the
                  discretion of each of the Lenders, subject to contractual
                  commitments of the Lenders to the Co-Borrowers;

                  (ii) each is an "accredited investor" as such term is defined
                  in Rule 501 of Regulation D of the Securities Act;

                  (iii) they has been given access to all information they
                  deemed reasonably necessary to evaluate their investment in
                  the Co-Borrowers; and

                  (iv) they have such experience and knowledge in financial and
                  business matters to be capable of evaluating the merits and
                  risks of their investment in the Co-Borrowers and have
                  reviewed the merits of such investment with tax and legal
<PAGE>   23
                  counsel and other advisors to the extent they deemed
                  advisable.

                  (b) The Lenders covenant that they will not sell or otherwise
transfer the Notes except pursuant to an effective registration statement under
the Securities Act and in compliance with state securities laws, or in a
transaction which, in the opinion of counsel reasonably satisfactory to the
Co-Borrowers, is exempt from registration under the Securities Act and under
applicable state securities laws.

                  (c) The Lenders understand that the Notes have not been
registered under the Securities Act in reliance on an exception therefrom under
Section 4(2) of the Securities Act, and that such securities shall bear the
following legend:

                  "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES LAWS
                  AND MAY NOT BE OFFERED, SOLD OR TRANSFERRED EXCEPT (I)
                  PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED, AND IN COMPLIANCE WITH
                  STATE SECURITIES LAWS OR (II) IN A TRANSACTION WHICH, IN THE
                  OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE SKYLINE
                  MULTIMEDIA ENTERTAINMENT, INC., IS EXEMPT FROM REGISTRATION
                  THEREUNDER AND UNDER APPLICABLE STATE SECURITIES LAWS."

                  The Co-Borrowers shall remove such legend upon receipt of an
opinion from counsel to the Lenders, reasonably satisfactory in form and
substance to counsel to the Co-Borrowers, that the requirements for such legend
have terminated.


                  8.5   Confidentiality.

                  (a) As to so much of the information and other material
furnished under or in connection with this Agreement (whether furnished before,
on or after the date hereof, including without limitation information furnished
pursuant to Sections 5.1 and 5.2 hereof) as constitutes or contains confidential
business, financial or other information of the Co-Borrowers, the Lenders
covenant that:

                  (i) the Lenders shall not, provided that the Co-Borrowers have
                  given written notice to the Lenders of the confidential nature
                  of such information, disclose such information to Persons
                  other than their respective employees, counsel, accountants,
                  shareholders, members, partners, limited partners, officers,
                  directors and agents (which Persons shall be advised of the
                  confidential nature of such information);

                  (ii) the Lenders shall not use such information other than in
                  connection with evaluating or monitoring the Lenders'
                  investment in the Co-Borrowers; and
<PAGE>   24
                  (iii) the Lenders shall not use such information in a manner
                  known by the Lenders to be adverse to the Co-Borrowers, or its
                  business or assets;

provided, however, that the foregoing obligation shall not apply if:

                  (A) the Lenders are advised by their respective legal counsel
                  that such disclosure or delivery may be required by law,
                  regulation or judicial or administrative order;

                  (B) such information is otherwise in the public domain at the
                  time of disclosure, or becomes publicly known, in each case,
                  through no breach of this Agreement or any other obligation by
                  the Lenders;

                  (C) such information becomes known to the Lenders through
                  disclosure by sources other than the Co-Borrowers having the
                  right to disclose such confidential information without any
                  restriction thereon;

                  (D) such information is generally disclosed to third parties
                  by the Co-Borrowers without similar restriction on such third
                  parties;

                  (E) such information is approved for release by written
                  authorization of the Co-Borrowers;

                  (F) such information is independently developed by such
                  Lender;

                  (G) such Lender uses such information in connection with any
                  litigation or arbitration for the purpose of enforcing its
                  rights against the Co-Borrowers under this Agreement or any
                  Operative Agreement; or

                  (H) such information is disclosed in connection with a
                  transfer or proposed transfer of securities of the
                  Co-Borrowers and the transferee or proposed transferee agrees
                  prior to such disclosure to be bound by this Section 8.5.

                  8.6 Further Assurances, Post-Closing Cooperation. At any time
or from time to time after each Closing, the Co-Borrowers shall execute and
deliver to each of the Lenders such other documents and instruments, provide
such materials and information and take such other actions as either of the
Lenders may reasonably request more effectively to vest title to a Note in such
Lender and otherwise to cause the Co-Borrowers to fulfill their respective
obligations under this Agreement and the Operative Agreements to which they are
a party.

                  8.7 Amendments and Waivers. No amendment, modification,
termination or waiver of any provision of this Agreement or of the Notes, or
consent to any departure by the Co-Borrowers therefrom, shall in any event be
effective unless in writing and signed by both the Lenders and the Co-Borrowers.
Any waiver or consent shall be effective only in the specific instance and for
the specific purpose for which it was given. No notice to or demand on the
<PAGE>   25
Co-Borrowers in any case shall entitle the Co-Borrowers to any further notice or
demand in similar or other circumstances, unless otherwise specifically required
herein. Any amendment, modification, termination, waiver or consent effected in
accordance with this Section 8.7 shall be binding upon the holder of the Notes
and each future holder of the Notes.

                  8.8 Independence of Covenants. All covenants hereunder
shall be given independent effect so that if a particular action or condition is
not permitted by any of such covenants, the fact that it would be permitted by
an exception to, or be otherwise within the limitation of, another covenant
shall not avoid the occurrence of an Event of Default or Potential Event of
Default if such action is taken or condition exists.

                  8.9 No Third Party Beneficiary. The terms and provisions of
this Agreement are intended solely for the benefit of each party hereto and
their respective successors or permitted assigns, and it is not the intention of
the parties to confer third-party beneficiary rights, and this Agreement does
not confer any such rights, upon any other Person other than any Person entitled
to indemnity under Section 8.2.

                  8.10 Assignment; Binding Effect. Neither this Agreement nor
any right, interest or obligation hereunder may be assigned by the Co-Borrowers
without the prior written consent of both of the Lenders and any attempt to do
so will be void. Subject to the foregoing sentence, this Agreement is binding
upon, inures to the benefit of and is enforceable by the parties hereto and
their respective successors and assigns.

                  8.11 Headings. The headings used in this Agreement have
been inserted for convenience of reference only and do not define or limit the
provisions hereof.


                  8.12 Invalid Provisions. If any provision of this Agreement
is held to be illegal, invalid or unenforceable under any present or future Law,
and if the rights or obligations of any party hereto under this Agreement will
not be materially and adversely affected thereby, (a) such provision will be
fully severable, (b) this Agreement will be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof,
(c) the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom and (d) in lieu of such illegal, invalid
or unenforceable provision, there will be added automatically as a part of this
Agreement a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible.

                  8.13 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF NEW YORK WITHOUT
GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER

APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.

SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR
SHALL LIMIT THE RIGHT OF THE LENDERS TO BRING PROCEEDINGS AGAINST THE
CO-BORROWERS IN THE COURTS OF ANY OTHER JURISDICTION.

                  8.15 Waiver of Jury Trial. THE CO-BORROWERS HEREBY WAIVE,

                           Senior Secured Demand Note

$435,000                                                  May 20, 1998 
                                                         New York, New York No.2

                  FOR VALUE RECEIVED, Skyline Multimedia Entertainment, Inc., a
New York corporation (the "Company"), New York Skyline, Inc., a New York
corporation ("NYSI"), Skyline Virtual Reality, Inc., a Delaware corporation
("SVR"), Skyline Chicago, Inc., a Delaware corporation ("SCI"), Skyline Magic,
Inc., a Delaware corporation ("SMI") and Skyline Las Vegas, Inc., a Delaware
corporation ("SLVI"), hereby promise to pay to Prospect Street NYC Discovery
Fund, L.P., or its registered successors or assigns (the "Registered Holder"),
Four Hundred Thirty Five Thousand U.S. Dollars ($435,000.00) on demand given on
or after July 15, 1998 (the date of such demand referred to herein as the
"Maturity Date") in accordance with the provisions of this Note. This Note is
issued by the Company pursuant to the Senior Secured Credit Agreement, dated as
of May 20, 1998 (as such agreement may be amended, modified or restated from
time to time, the "Credit Agreement"), by and among the Company, the Company's
subsidiaries, the
<PAGE>   2
Registered Holder and The Bank of New York, as trustee for the Employees
Retirement Plan of Keyspan Energy Corp. This Note is secured by the collateral
pledged to the Registered Holder pursuant to the Collateral Documents (as
defined herein). All capitalized terms used and not defined herein shall have
the meaning ascribed to such terms in the Credit Agreement.

                 "Collateral Documents" means the Security Agreement, the
Subordination Agreement, the Subsidiary Stock Pledge Agreement, the Subsidiary
Guarantee, and the Indemnity, Subrogation and Contribution Agreement (in each
case, as the same may be amended, modified or restated from time to time), and
all certificates, schedules, exhibits and other documents required to be
delivered in connection with such agreements.

                  1. Interest. Interest will accrue on the unpaid principal
amount of this Note from the date hereof at a rate of 14% per annum; provided,
however, that, upon an Event of Default under Section 7.1 of the Credit
Agreement, the rate of interest shall increase to a rate per annum of 21%.
Interest accrued on this Note shall be payable on the earlier of (a) the
Maturity Date, and (b) the date of consummation of an Equity Financing. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

                  2. Method of Payment. The Company will pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. The Company shall pay principal
and interest on this Note by wire transfer of immediately available funds to the
account specified by the Registered Holder in a written notice to the Company
delivered at least three Business Days prior to such payment date. If a payment
date is other than a Business Day, payment shall be made on the next succeeding
Business Day. All payments shall be applied first, to all accrued and unpaid
interest hereon, and second, to principal.

                  3. Prepayment. At its option, the Company may, from time to
time, prepay all or any portion of the principal amount of this Note in cash.
Written notice of prepayment under this Section 3 shall be given to the
Registered Holder at least 5 days but not more than 30 days before the
prepayment date set forth in such notice at the address provided in or pursuant
to Section 9 herein. Any such prepayment shall be in an amount of at least
$100,000 and in integrals of $10,000, or such lesser amount as equals the then
outstanding principal amount of this Note being prepaid, and shall be
accompanied by the cash payment of all accrued and unpaid interest on the
portion of the principal then being prepaid. Once due notice of prepayment is
given, a portion of the principal amount of this Note (in such amount as the
notice states shall be prepaid) shall become due and payable on the optional
prepayment date.

                  4. Repayment. The Company will repay this Note in full, in
cash on the Maturity Date at 100% of the then outstanding principal amount of
this Note plus accrued but unpaid interest thereon to such date.

                  5. Optional Conversion. In the event that an Equity Financing
has been consummated prior to July 15, 1998, the holders of this Note may, at
their option, convert all, but not less than all, of the principal amount of
this Note such that each $1.00 of principal
                               
<PAGE>   3
amount of this Note shall convert into that number of units of securities
offered in such Equity Financing as are purchaseable for $1.25. Upon such
conversion, accrued and unpaid interest hereon shall be immediately payable to
the Registered Holder in cash.

                  6. Events of Default; Remedies. Events of Default and the
consequences of Events of Default are set forth in Article VII of the Credit
Agreement. All provisions of Article VII of the Credit Agreement are
specifically hereby incorporated herein in full by this reference.

                  7. Note Exchangeable for Different Denominations. This Note is
exchangeable, upon the surrender hereof by the Registered Holder at the
principal office of the Company, without expense to the Registered Holder, for a
Note or Notes, dated as of the date to which interest has been paid on the
unpaid principal amount of the Note or Notes so exchanged, or, if no interest
has been paid thereon, then dated as of the date of the Note or Notes so
exchanged, each in the principal amount of $250,000, or any multiple thereof (or
in any such lesser amount as shall equal the then unpaid principal amount of the
Note or Notes so exchanged), for the same aggregate unpaid principal amount as
the Note or Notes so surrendered for exchange and each payable to such Person or
Persons, or order, as may be designated by such Registered Holder (subject to
Section 15 herein); provided, however, that upon any such exchange there shall
be filed with the Company the name and address for all purposes hereof of the
payee of each Note delivered in the exchange for this Note and such exchanged
Note shall in all other respects be in the same form and have the same terms as
this Note.

                  8. Replacement. Upon receipt of evidence reasonably
satisfactory to the Company (an affidavit of the Registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
this Note, and in the case of any such loss, theft or destruction, upon receipt
of indemnity reasonably satisfactory to the Company (provided that if the
Registered Holder is a financial institution or other institutional investor its
own sworn or notarized agreement shall be satisfactory) or, in the case of any
such mutilation upon surrender of this Note, the Company shall (at its expense)
execute and deliver in lieu of such Note, a Note of like kind representing the
same rights represented by such lost, stolen, destroyed or mutilated Note and
dated as of the date to which interest has been paid on the unpaid principal
amount of the Note so lost, stolen, destroyed or mutilated, or, if no interest
has been paid thereon, then dated as of the date of the Note so lost, stolen,
destroyed or mutilated.

                  9. Securities Act. This Note has not been registered under the
Securities Act of 1933 and applicable state securities laws. Therefore, the
Company may require, as a condition of allowing the transfer or exchange of this
Note, that the Registered Holder furnish to the Company an opinion of counsel
reasonably acceptable to the Company to the effect that such transaction is
allowable under the Securities Act of 1933 and applicable state securities laws.

                  10. Notices. All notices, requests and other communications
hereunder must be in writing and will be deemed to have been duly given only if

                          COMMON STOCK PURCHASE WARRANT


Date of Issuance:         , 1998                        Certificate No. 2
                 ----- ---                                             ---


         For value received, SKYLINE MULTIMEDIA ENTERTAINMENT, INC., a New York
corporation (the "Company"), hereby grants to Prospect Street NYC Discovery
Fund, L.P. and or its registered assigns (the "Registered Holder"), the right to
purchase from the Company, subject to the terms and conditions herein contained
that number of shares of common stock par value $.001 of the Company (the
"Warrant Shares") as set forth in Section 1A hereof, at a price per share of
$.375 (the "Exercise Price"). This Warrant is issued pursuant to the Senior
Secured Credit Agreement dated as of May 20, 1998, by and among the Company, the
other Borrowers named therein and the Lenders named therein (as such agreement
may be amended, modified or restated from time to time, the "Credit Agreement").
Certain capitalized terms used herein are defined in Section 2 hereof. All other
capitalized terms used and not defined herein shall have the meaning ascribed to
such terms in the Credit Agreement.

         This Warrant is subject to the following provisions:

         SECTION 1.        Exercise of Warrant.

         1A. Exercise Period. The purchase rights represented by this Warrant
may be exercised only upon the happening of the following events and for the
amount of shares stated:

                  (i)      In the event the entire principal amount of the Notes
                           (plus all accrued and unpaid interest thereon) is
                           repaid prior to July 15, 1998, then this Warrant
                           shall be exerciseable into such number of shares of
                           Common Stock that equals 32% of such Common Stock on
                           a Fully Diluted Basis on the date of such issuance;
                           or

                  (ii)     In the event the entire principal amount of the Notes
                           has not been repaid (plus all accrued and unpaid
                           interest thereon) or converted (pursuant to the terms
                           of the Notes) prior to July 15, 1998, then this
                           Warrant shall be exercisable into such number of
                           shares of Common Stock that equal
<PAGE>   2
                           47.167% of the Common Stock on a Fully Diluted Basis
                           at the time of issuance. Upon consummation of an
                           Equity Financing and repayment or conversion of the
                           entire principal amount of the Notes (plus all
                           accrued and unpaid interest thereon) before July 15,
                           1998, this Warrant shall be cancelled and of no
                           further force and effect.

         1B.      Exercise Procedure.

                  (i) This Warrant shall be deemed to have been exercised when
all of the following items have been delivered to the Company (the "Exercise
Time"):

                      (a) a completed Exercise Agreement, as described in
Section 1C below, executed by the Person exercising all or part of the purchase
rights represented by this Warrant (the "Purchaser");

                      (b) this Warrant;

                      (c) if the Purchaser is not the Registered Holder, an
Assignment or Assignments in the form set forth in Exhibit II hereto evidencing
the assignment of this Warrant to the Purchaser; and

                      (d) either (i) a check payable to the Company in an amount
equal to the Exercise Price multiplied by the number of Warrant Shares being
purchased upon such exercise (the "Aggregate Exercise Price"), (ii) the
surrender to the Company of debt or equity securities of the Company or any of
its direct or indirect subsidiaries having a value equal to the Aggregate
Exercise Price of the Warrant Shares being purchased upon such exercise (which
value in the case of debt securities or any preferred stock shall be deemed to
equal the aggregate outstanding principal amount or liquidation value thereof
plus all accrued and unpaid interest thereon or accrued or declared and unpaid
dividends thereon and in the case of shares of Common Stock shall be the Fair
Market Value thereof), or (iii) the delivery of a notice to the Company that the
Purchaser is exercising the Warrant (or portion thereof) by authorizing the
Company to reduce the number of Warrant Shares subject to such exercise of the
Warrant or portion thereof by the number of shares having an aggregate Fair
Market Value determined as of the date immediately prior to the date of the
Exercise Time equal to the Aggregate Exercise Price.

                  (ii) Certificates for Warrant Shares purchased upon exercise
of this Warrant shall be delivered by the Company to the Purchaser within five
days after the date of the Exercise Time.

                  (iii) The Warrant Shares issuable upon the exercise of this
Warrant shall be deemed to have been issued to the Purchaser at the Exercise
Time, and the Purchaser shall be deemed for all purposes to have become the
Registered Holder of such Warrant Shares at the Exercise Time.

                  (iv) The issuance of certificates for Warrant Shares upon
exercise of this 
<PAGE>   3
Warrant shall be made without charge to the Registered Holder or the Purchaser
for any issuance tax in respect thereof or other cost incurred by the Company in
connection with such exercise and the related issuance of Warrant Shares;
provided, however, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issuance
of any Warrants or any certificates representing Warrant Shares in a name other
than that of a Registered Holder, and the Company shall not be required to issue
or deliver such Warrant or certificate for Warrant Shares unless and until the
Person requesting the issuance thereof shall have paid to the Company the amount
of such tax or shall have established to the reasonable satisfaction of the
Company that such tax has been paid.

                  (v) The Company shall not close its books against the transfer
of this Warrant or of any Warrant Shares issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant.

                  (vi) The Company shall assist and cooperate with any
reasonable request by the Registered Holder or Purchaser in connection with any
governmental filings or approvals required to be obtained or made by any of them
prior to or in connection with any exercise of this Warrant (including, without
limitation, making any filings or obtaining any approvals required to be made or
obtained by the Company).

                  (vii) The Company shall at all times reserve and keep
available out of its authorized but unissued Warrant Shares solely for the
purpose of issuance upon the exercise of this Warrant, the maximum number of
Warrant Shares issuable upon the exercise of this Warrant, or, if such unissued
Warrant Shares are insufficient to comply with such reserve requirement, the
Company shall use its best efforts to increase the authorized capital stock of
the Company in an amount sufficient to comply herewith and submit such proposal
for approval by the Company's shareholders at the next annual meeting of
shareholders of the Company. All Warrant Shares which are so issuable shall,
when issued and upon the payment of the applicable Exercise Price, be duly and
validly issued, fully paid and nonassessable and free from all taxes, liens and
charges. The Company shall take all such actions as may be necessary to ensure
that all such Warrant Shares may be so issued without violation by the Company
of any applicable law of governmental regulation or any requirements of any
domestic securities exchange upon which shares of Common Stock or other
securities constituting Warrant Shares may be listed (except for official notice
of issuance which shall be immediately delivered by the Company upon each such
issuance). The Company will cause the Warrant Shares, immediately upon such
exercise, to be listed on any domestic securities exchange upon which shares of
Common Stock or other securities constituting Warrant Shares are listed at the
time of such exercise.

         1C. Exercise Agreement. Upon any exercise of this Warrant, the
Purchaser shall deliver to the Company an Exercise Agreement in substantially
the form set forth in Exhibit I hereto, except that if the Warrant Shares are
not to be issued in the name of the Registered Holder, the Exercise Agreement
shall also state the name of the Person to whom the certificates for the Warrant
Shares are to be issued, and if the number of Warrant Shares to be issued does
not include all of the Warrant Shares purchasable hereunder, it shall also state
the name of the Person to whom a new Warrant for the unexercised portion of the
rights hereunder is to be
<PAGE>   4
issued.

         SECTION 2. Definitions. The following terms have the meanings set forth
below:

         "Common Stock" means the common stock, par value $.001 per share and
the Class A common stock, par value $.001 per share (the "Class A Common
Stock"), of the Company, any securities into which such common stock shall have
been changed or any securities resulting from any reclassification or
recapitalization of such common stock and Class A Common Stock, and all other
securities of any class or classes (however designated) of the Company the
holders of which have the right, without limitation as to amount, after payment
on any securities entitled to a preference on dividends or other distributions
upon any dissolution or winding up, either to all or to a share of the balance
of payments upon such dissolution, liquidation or winding up.

         "Equity Financing " has the meaning ascribed thereto in the Credit
Agreement.

         "Fair Market Value" means (i) the average of the closing sales prices
of the Common Stock on all domestic securities exchanges on which the Common
Stock is listed, or (ii) if there 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, (iii) if on any day the Common Stock is not
so listed, the sales price for the Common Stock as of 4:00 P.M., New York time,
as reported on the Nasdaq Stock Market or, (iv) if the Common Stock is not
reported on the Nasdaq Stock Market, the average of the representative bid and
asked quotations for the Common Stock as of 4:00 P.M., New York time, as
reported on the Nasdaq interdealer quotation system, or any similar successor
organization, in each such case averaged over a period of 21 trading days
consisting of the day as of which "Fair Market Value" is being determined and
the immediately prior 20 trading days prior to such day during which the Common
Stock was traded. Notwithstanding the foregoing, if at any time of determination
either (x) the Common Stock is not registered pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended, and then listed on a national
securities exchange or authorized for quotation in the Nasdaq system, or (y)
less than 25% of the outstanding Common Stock is held by the public free of
transfer restrictions under the Securities Act of 1933, as amended, then Fair
Market Value shall mean the price that would be paid per share for the entire
common equity interest in the Company in an orderly sale transaction between a
willing buyer and a willing seller, using valuation techniques then prevailing
in the securities industry, and assuming full disclosure of all relevant
information and a reasonable period of time for effectuating such sale, without
discount for lack of liquidity, or minority position. Fair Market Value shall be
determined jointly by the Company's Board of Directors in its good faith
judgment and the Required Holders; provided that, if such parties are unable to
so agree within 15 days, such value shall be determined by an independent
investment banking or appraisal firm mutually acceptable to the Company and the
Required Holders, which firm shall submit to the Company and the Warrant holders
a written report setting forth such determination. The fees and expenses of such
firm will be borne by the Company, and the determination of such firm will be
final and binding upon all parties.

         "Fully Diluted Basis" means, with respect to the calculation of the
number of shares of Common Stock, all shares of Common Stock outstanding at the
time of determination and all
<PAGE>   5
shares issuable upon the exercise of options or convertible or exchangeable
securities or warrants (giving effect to the Warrant Shares issuable hereunder).

         "Person" means any natural person, corporation, general partnership,
limited partnership, proprietorship, limited liability company, limited
liability partnership, other business organization, trust, union, association or
governmental or regulatory authority.

         "Required Holders" means the holders representing a majority of the
Warrants Shares issuable upon exercise of the Warrants.

         "Warrant Shares" means shares of the Company's Common Stock issued
under this Warrant; provided, that if the securities issuable upon exercise of
the Warrants are issued by an entity other than the Company or there is a change
in the class of securities so issuable, then the term "Warrant Shares" shall
mean shares of the security issuable upon exercise of the Warrants if such
security is issuable in shares, or shall mean the equivalent units in which such
security is issuable if such security is not issuable in shares.

         SECTION 3. No Voting Rights; Limitations of Liability. This Warrant
shall not entitle the Registered Holder hereof to any voting rights or other
rights as a stockholder of the Company. No provision hereof, in the absence of
affirmative action by the Register Holder to purchase Warrant Shares, and no
enumeration herein of the rights or privileges of the Registered Holder shall
give rise to any liability of such Registered Holder for the Exercise Price of
Warrant Shares acquirable by exercise hereof or as a stockholder of the Company.

         SECTION 4. Warrant Transferable. Subject to the transfer conditions
referred to in the legend endorsed hereon, this Warrant and all rights hereunder
are transferable, in whole or in part, without charge to the Registered Holder
(subject to the provisions of paragraph 1B(iv) hereof), upon surrender of this
Warrant with a properly executed Assignment (in the form of Exhibit II hereto)
at the principal office of the Company.

         SECTION 5. Warrant Exchangeable for Different Denominations. This
Warrant is exchangeable, upon the surrender hereof by the Registered Holder at
the principal office of the Company, for new Warrants of like tenor representing
in the aggregate the purchase rights hereunder, and each of such new Warrants
shall represent such portion of such rights as is designated by the Registered
Holder at the time of such surrender. All Warrants representing portions of the
rights hereunder are referred to herein as the "Warrants."

         SECTION 6. Exchange. In the event that it becomes unlawful or, in the
reasonable judgment of any Registered Holder of this Warrant, unduly burdensome
by reason of a change in legal or regulatory considerations or the
interpretation thereof affecting such Registered Holder, or any material change
(including a reduction in the number of shares of Common Stock outstanding) in
the capital structure of the Company, to hold any or all of the Warrants or
Warrant Shares, the Registered Holder of this Warrant shall have the right to
require the Company to use its best efforts to permit all or part of such
Registered Holder's Warrants or Warrant Shares to be exchanged for nonvoting
stock or similar interests that convey equivalent
<PAGE>   6
economic benefits to such Warrants or Warrant Shares. To the extent that the
Company may lawfully do so after the exercise of its best efforts, any such
exchange shall occur as soon as practicable but in any event within 60 days
after written notice by the Registered Holder of this Warrant to the Company (or
such earlier date if required to comply with applicable law).

         SECTION 7. Replacement. Upon receipt of evidence reasonably
satisfactory to the Company (an affidavit of the Registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing this Warrant, and in the case of any such loss, theft
or destruction, upon receipt of indemnity reasonably satisfactory to the Company
(provided that if the Registered Holder is a financial institution or other
institutional investor its own agreement shall be satisfactory), or, in the case
of any such mutilation upon surrender of such certificate, the Company shall (at
its expense) execute and deliver in lieu of such certificate a new certificate
of like kind representing the same rights represented by such lost, stolen,
destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate.

         SECTION 8. Notices. Except as otherwise expressly provided herein, all
notices and deliveries referred to in this Warrant shall be in writing, shall be
delivered personally, sent by registered or certified mail, return receipt
requested and postage prepaid or sent via nationally recognized overnight
courier or via facsimile, and shall be deemed to have been given when so
delivered (or when received, if delivered by any other method) if sent (i) to
the Company, at its principal executive offices and (ii) to a Registered Holder,
at such Registered Holder's address as it appears in the records of the Company
(unless otherwise indicated by any such Registered Holder).

         SECTION 9. Amendment and Waiver. Except as otherwise provided herein,
the provisions of the Warrants may be amended and the Company may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the prior written consent of
the Required Holders.

         SECTION 10. Warrant Register. The Company shall maintain at its
principal executive offices books for the registration and the registration of
transfer of Warrants. The Company may deem and treat the Registered Holder as
the absolute owner hereof (notwithstanding any notation of ownership or other
writing thereon made by anyone) for all purposes and shall not be affected by
any notice to the contrary.

         SECTION 11. Fractions of Shares. The Company may, but shall not be
required to, issue a fraction of a Warrant Share upon the exercise of this
Warrant in whole or in part. As to any fraction of a share which the Company
elects not to issue, the Company shall make a cash payment in respect of such
fraction in an amount equal to the same fraction of the Fair Market Value of a
Warrant Share on the date of such exercise.

         SECTION 12. Descriptive Headings; Governing Law. The descriptive
headings of the several Sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. THIS AGREEMENT
SHALL BE GOVERNED BY AND
<PAGE>   7
CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF NEW YORK WITHOUT
GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER
OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE
APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.

                                    * * * * *

All of the foregoing property described in this Section 1 and any part thereof
as to each Grantor or collectively, the Grantors, as the case may be, is
hereinafter called "Collateral". The security interest granted hereby shall be
continuing and shall secure all present and future Obligations whether or not at
some prior point in time all Obligations then outstanding shall have been
satisfied.

                  Section 2. Representations and Warranties. (a) The chief
executive office of each of the Grantors is as set forth on Schedule B. Except
for the Lenders' security interest hereunder, Liens not involving amounts in
excess of $10,000 and as otherwise described on Schedule C hereto, each Grantor
hereby warrants and represents that it is the sole owner of the Collateral
attributable to it, free from any Lien, claim, set-off, defense or counterclaim;
that all items of Collateral are in all respects what they purport to be; that
there is no financing statement now on file in any public office covering any
Collateral; and there is no fact that would impair its title to the Collateral,
the Collateral's validity or enforceability, each Grantor's ability to perform
its obligations hereunder, the Lenders' rights hereunder, or the validity or
first priority of the security interest and lien upon the Collateral created by
this Agreement.

                  (b) As of the date hereof, none of the Grantors own or uses
any Copyrights, Patents or Trademarks or any Copyrights, Patents or Trademarks
registered in, or the subject of pending applications in, the United States
Copyright Office or United States Patent and Trademark Office or any similar
office or agency or any other country or any political subdivision thereof,
other than those described in Schedule D, Schedule E, and Schedule F hereto,
respectively.

                  (c) Grantors further warrant that they are aware of no
significant third party claim that any aspect of any Grantors' present or
contemplated business operations infringes or will infringe any Trademarks.
Grantors represent and warrant that all United States Trademark registrations
and applications listed in Schedule F are valid, subsisting and have not been
canceled and that except as listed in Schedule F, Grantors are not aware of any
third-party claim that any of said registrations is invalid or unenforceable. To
the best knowledge of Grantors, Grantors have used or intend to use the
Trademarks to identify themselves, as the case may be, and the goods and
services covered by the Trademarks and all registrations thereof are subsisting
and in full force and effect.

                  (d) Grantors represent and warrant that they own or are
licensed to practice under all Patents and Copyrights that they now own or
practice under. Grantors further warrant that they are aware of no significant
third party claim that any aspect of Grantors' present or contemplated business
operations infringes or will infringe any Patent or any Copyright of any third
party. The Copyrights shown on Schedule D hereto, unless otherwise stated
therein, are duly recorded or filed for recording in the United States Copyright
Office. The Patent registrations shown on Schedule E hereto, unless otherwise
stated therein, are valid and subsisting and in full force and effect. None of
the Patents has been abandoned or dedicated, and, except to the extent that the
Lenders, upon prior written notice by Grantors, shall consent, and Grantors will
not do any act, or omit to do any act, whereby the Patents may become abandoned 

<PAGE>   5
or dedicated and shall notify the Lenders immediately if it knows of any reason
or has reason to know that any application or registration may become abandoned
or dedicated.

                  (e) In no event shall any Grantor, either itself or through
any agent, employee, licensee or designee, (i) file an application for the
registration of any Copyright, Patent or Trademark with the United States
Copyright Office or United States Patent and Trademark Office or any similar
office or agency of any other country or any political subdivision thereof or
(ii) file any assignment of or grant of security interest in any Copyright,
Patent or Trademark that any Grantor may acquire from a third party, with the
United States Copyright Office or United States Patent and Trademark Office or
any similar office or agency of any other country or any political subdivision
thereof, unless such Grantor shall, on or prior to the date of such filing,
notify the Lenders thereof, and upon request of the Lenders, execute and deliver
any and all assignments, agreements, instruments, documents and papers as the
Lenders may request to evidence the Lenders' interest in such Copyright, Patent
or Trademark and the goodwill and general intangibles of such Grantor relating
thereto or represented thereby, and such Grantor hereby constitutes each Lender
its attorney-in-fact to execute and file all such writings for the foregoing
purposes, all acts of such attorney being hereby ratified and confirmed; such
power being coupled with an interest is irrevocable until the Obligations are
paid in full.

                  (f) Grantors will perform all acts and execute all documents,
including, without limitation, grants of security interest in form suitable for
filing with the United States Copyright Office and United States Patent and
Trademark Office, substantially in the forms of Exhibit 1, Exhibit 2 and Exhibit
3 hereto, respectively, reasonably requested by the Lenders at any time to
evidence, perfect, maintain, record and enforce the Lenders' interest in the
Collateral or otherwise in furtherance of the provisions of this Agreement.

                  (g) Grantors will take all steps reasonably necessary in any
proceeding before the United States Copyright Office or United States Patent and
Trademark Office or any similar office or agency of any other country or any
political subdivision thereof, to maintain each application and registration of
the Copyrights, Trademarks and Patents.

                  (h) Grantors assume all responsibility and liability arising
from the use of the Copyrights, Patents and Trademarks, and each Grantor hereby
indemnifies and holds each Lender harmless from and against any claim, suit,
loss, damage or expense (including reasonable attorneys' fees) arising out of
any alleged defect in any product manufactured, promoted or sold by any Grantor
in connection with any Copyright, Patent or Trademark or out of the manufacture,
promotion, labeling, sale or advertisement of any such product by such Grantor.
Each Grantor agrees that the Lenders do not assume, and shall have no
responsibility for, the payment of any sums due or to become due under any
agreement or contract included in the Collateral or the performance of any
obligations to be performed under or with respect to any such agreement or
contract by such Grantor, and each Grantor hereby indemnifies and holds each
Lender harmless with respect to any and all claims by any person relating
thereto.

                  (i) All licenses with respect to Patents, Trademarks or
Copyrights, or any other license or sublicense, to which any Grantor is a party
are set forth on Schedule G hereto.
<PAGE>   6
                  Section 3. Location and Use of Collateral. Grantors shall:

                  (i) keep all Inventory and all records pertaining to
Collateral, at or affixed to the location of its chief executive office set
forth on Schedule B or such other place or places as it may designate in a
writing delivered to the Lenders thirty (30) days before moving such Collateral
or records to another place, and may use such Collateral only for purposes for
which it is commonly employed in Grantors' type of business;

                  (ii) as soon as practicable after the date hereof, but in any
event within sixty (60) days after such an item of property becomes Collateral,
deliver to the Lenders all Instruments, Documents and Chattel Paper that are
Collateral, with all endorsements or assignments necessary, or in the Lenders'
judgment reasonably appropriate, for each item of such Collateral to be
transferable; and

                  (iii) keep the proceeds of all Collateral segregated from
property that is not Collateral or proceeds thereof so that it may readily be
identified as proceeds of Collateral.

                  Section 4. Financing Statements and Notice. Grantors hereby
authorize the Lenders, without notice or the signature of any Grantor, to file
any financing statements and any amendments thereto or continuations thereof,
naming each Grantor as debtor and the Lenders as secured parties. At the
Lenders' request, each Grantor will join with the Lenders in executing any such
financing statements, amendments or continuations. In order to perfect, maintain
or protect its security interest, the Lenders may give notice of its security
interest in Collateral and may deliver a copy of this Agreement to any Person.

                  Section 5. Preservation of Collateral and Security Interest.
(a) Each Grantor shall maintain tangible Collateral in at least as good
condition as it is on the date hereof or when acquired by such Grantor, ordinary
wear and tear excepted, and not permit anything to be done that will materially
impair the value of any Collateral. Each Grantor shall at all times keep
accurate and complete records with respect to Collateral and shall furnish to
the Lenders upon request copies of its records relating to Collateral and all
additional information reasonably requested by the Lenders. The respective
representatives of the Lenders shall, during reasonable business hours and upon
notice given two Business Days in advance, have the right to enter upon any
Grantor's premises, inspect Collateral, and examine and make copies of such
Grantor's records relating to Collateral at such Grantor's expense.

                  (b) No Grantor shall make an assignment, pledge, mortgage, or
other transfer of Collateral or any interest in it other than in the ordinary
course of its business, and shall keep all Collateral free from all Liens;
provided, however, that the foregoing limitations shall not apply to (i)
purchase money security interests or capital lease transactions in connection
with the purchase or lease of Equipment to be used by such Grantor in the
ordinary course of its business or (ii) such other dispositions of Collateral as
the Lenders may approve in writing in advance. Within ten (10) days of its
occurrence, Grantors shall give written notice to the Lenders of any material
loss of, or material damage to, Collateral; Grantors shall give immediate
written notice to the 
<PAGE>   7
Lenders of any Lien, against or upon Collateral having such value which shall
not be discharged, released or satisfied within ten (10) days. The Lenders, at
their option, may pay or cause the discharge of taxes, Liens at any time levied
or placed on Collateral, take any action to maintain and preserve Collateral and
remedy any breach of any Grantor hereunder. Each Grantor shall do, execute and
deliver all additional acts, deeds, and instruments as the Lender may require,
to more completely vest in and assure to the Lenders their rights hereunder.

                  Section 6. Limitation on Modifications of Accounts. No Grantor
will, without the prior written consent of the Lenders, grant any extension for
the time of payment of any of the Accounts, compromise, compound or settle the
same for less than the full amount thereof, release, wholly, or partly, any
Person liable for the payment thereof, or allow any credit or discount
whatsoever thereon other than extensions, credits, discounts, compromises or
settlements granted or made in the ordinary course of business; provided,
however, that so long as no Event of Default (as defined in Section 8) has
occurred or is continuing, any Grantor may, without the prior written consent of
the Lender, allow in the ordinary course of business as adjustments to amounts
owing under its Accounts (i) an extension or renewal of the time or times of
payment, or the settlement for less than the total unpaid balance, which such
Grantor finds appropriate in accordance with sound business judgment and (ii) a
refund or credit due as a result of returned, damaged or non-conforming
merchandise.

                  Section 7. Insurance. Each Grantor will maintain insurance on
its respective portion of the Collateral in such amounts and with such coverage
as is reasonably satisfactory to the Lenders and as is consistent with coverage
usually carried by corporations of a similar size engaged in the same or similar
business similarly situated. Any proceeds received by any Grantor in payment for
loss of or damage to Collateral under such insurance shall be held in trust by
such Grantor and be Collateral hereunder; it shall be applied by such Grantor to
repair or replace the Collateral in respect of which it was received, and if not
so applied, to payment of Obligations. Each Grantor will give the Lenders
immediate written notice of the receipt by such Grantor and amount of any such
insurance proceeds and prior written notice of the manner in which such proceeds
shall be applied. Upon the Lenders' request, such Grantor shall deliver
certificates of such insurance to the Lender.

                  Section 8. Events of Default. (a) "Events of Default" shall
exist hereunder if:

                  (i) Any Grantor shall fail to perform any Obligation, or to
pay any sum to the Lenders, when and as due, whether by acceleration or
otherwise;

                  (ii) any representation or warranty of any Grantor set forth
herein shall prove to have been false or misleading in any material respect (if
not qualified by materiality) and in any respect (if qualified by materiality)
when made or deemed to have been made and, if such breach of representation or
warranty is capable of being cured within such time, such breach shall have
continued for ten (10) Business Days (A) after notice of such breach if such
Grantor has complied with Section 8(b) hereof or (B) after the date of such
breach if such Grantor has not complied with Section 8(b) hereof;

                  (iii) any obligation of any Grantor under this Agreement shall
not be complied 
<PAGE>   8
with and, if such noncompliance is capable of being cured within such time, such
noncompliance shall have continued for ten (10) Business Days (A) after notice
of such noncompliance if such Grantor has complied with Section 8(b) hereof or
(B) after the date of such noncompliance if such Grantor has not complied with
Section 8(b) hereof; or

                  (iv) an Event of Default as defined in the Credit Agreement
shall occur and be continuing.

                  (b) Each Grantor shall, promptly upon becoming aware thereof,
notify the Lenders in writing of any Event of Default and any condition or event
which, after notice or lapse of time or both, would constitute an Event of
Default if that condition or event were not cured or removed within any
applicable grace or cure period.

                  Section 9. Rights Following an Event of Default. Following and
during the continuance of an Event of Default, each of the following provisions
shall apply:

                  (a) the Lenders shall have all rights and remedies afforded by
the Uniform Commercial Code, to a secured creditor having a security interest in
property to which Article 9 thereof applies.

                  (b) Each Grantor will, upon receipt of any proceeds, dividend,
stock certificate or other sums arising from the sale or other disposition of
Collateral or any instrument evidencing an obligation to pay such sums, hold
same in trust for the Lenders in the form received, and will forthwith, without
notice or demand, endorse, transfer and deliver same to the Lenders, and, should
such Grantor obtain possession of goods, the sale or lease of which gave rise to
an Account, such Grantor shall hold same in trust for the Lenders subject to the
security interest hereunder.

                  (c) Each Grantor hereby irrevocably appoints each of the
Lenders its true and lawful agent to act in such Grantor's name or in such
Lender's name as fully and completely as though such Lender was the absolute
owners of Collateral for all purposes. Any Lender may exercise all of such
Grantor's rights of collection, enforcement, conversion or exchange and all
other similar rights, privileges and options pertaining to Collateral, all of
such Grantor's rights to commence, prosecute or settle any legal actions, give
releases, or settle or compromise any rights, with respect to Collateral, and
generally all of such Grantor's rights to sell, assign, transfer, pledge,
convey, make any agreement with respect to, or otherwise deal with, Collateral.
The Lender may execute and deliver any and all documents and take any and all
actions on behalf of such Grantor in order to carry out the provisions of this
Agreement.

                   Nothing herein shall be construed as requiring the Lenders to
make any demand or inquiry as to the nature or sufficiency of any payment, or to
take any action with respect to Collateral or moneys, proceeds or income due, or
to become due thereunder, and no such action taken or omitted to be taken, or
delay, by the Lender, shall give rise to any defense, counterclaim or set-off in
favor of any Grantor or to any claim or action against the Lenders. The Lenders
shall have the right, upon consultation with such Grantor, to communicate with
any account debtor of 
<PAGE>   9
such Grantor in order to verify Account balances from time to time, provided
that such verification right shall be exercised in a commercially reasonable
manner and pursuant to documentation and procedures acceptable to such Grantor.
The Lenders shall have the right, without prior notice to any Grantor, to notify
or to require such Grantor to notify the parties obligated on any Collateral to
make payment thereon directly to the Lenders. Each such Grantor shall give such
notice itself if requested to do so by the Lenders.

                  (d) No Grantor shall make any further use of the Copyrights,
Patents or Trademarks for any purpose without the consent of the Lenders and
shall, upon the request of the Lenders, use its best efforts to obtain all
requisite consents or approvals by the licensor of each license to which such
Grantor is a party, including but not limited to those set forth on Schedule G
hereto, to effect the assignment of all of Grantor's right, title and interest
thereunder to the Lenders or its designees.

                  (e) The Lenders may, at any time and from time to time, upon
fifteen (15) days' prior notice to the appropriate Grantor, license (whether
general, special or otherwise, and whether on an exclusive or nonexclusive
basis) any of the Copyrights, Patents or Trademarks, throughout the world for
such term or terms, on such conditions, and in such manner, as the Lenders shall
in its sole discretion determine.

                  (f) The Lenders may (without assuming any obligations or
liability thereunder) enforce, and shall have the exclusive right to enforce,
against any licensee or sublicensee all rights and remedies of each Grantor in,
to and under any one or more license agreements with respect to the Collateral,
and take or refrain from taking any action under any thereof, and each such
Grantor hereby releases the Lenders from, and agrees to hold the Lenders free
and harmless from and against any claims arising out of, any action taken or
omitted to be taken with respect to any such license agreement.

                  (g) The Lenders may apply the proceeds actually received from
any such license, assignment, sale or other disposition to the reasonable costs
and expenses thereof (including, without limitation, reasonable attorneys' fees
and all legal and other expenses which may be incurred by the Lenders), and then
to the Obligations, in such order as is set forth in this Agreement; and each
Grantor shall remain liable and will pay the Lenders on demand any deficiency
remaining, together with interest thereon at a rate equal to the highest rate
then payable on the Obligations and the balance of any expenses unpaid. Nothing
herein contained shall be construed as requiring the Lenders to take any such
action at any time.

                  In the event of any such license, assignment, sale or other
disposition of all or any part of the Collateral, after the occurrence or
continuation as hereinabove provided of an Event of Default, each Grantor shall
supply its know-how and expertise relating to the manufacture and sale of the
products bearing or in connection with the Copyrights, Trademarks or Patents,
and its customer lists and other records relating to the Copyrights, Trademarks
or Patents and to the distribution of said products, to the Lenders or their
designees.

                  (h) Concurrently with the execution and delivery hereof, each
Grantor is 
<PAGE>   10
executing and delivering to the Lenders, in the form of Exhibit 4 hereto,
originals of a Power of Attorney for the implementation of the assignment, sale
or other disposal of the Copyrights, Trademarks and Patents pursuant hereto, and
each Grantor hereby releases the Lenders from any claims, causes of action and
demands at any time arising out of or with respect to any actions taken or
omitted to be taken by the Lenders under the power of attorney granted herein,
other than actions taken or omitted to be taken through the gross negligence or
willful misconduct of the Lenders.

                  Section 10. Possession of Collateral. After and during the
continuance of an Event of Default, the Lenders shall be entitled, without
notice to any Grantor, to appointment of a receiver to take possession of
Collateral, and may require each Grantor to assemble Collateral and make the
same available to the Lenders at a place to be designated by the Lender
reasonably convenient to both parties. The Lenders' duty of care with respect to
Collateral shall be limited to the exercise of reasonable care. The Lenders
shall be deemed to have exercised reasonable care if Collateral is accorded
treatment requested by such Grantor in writing or substantially the same as that
the Lenders accord their own property. The Lenders shall not be deemed to have
failed to exercise reasonable care solely because it may have failed to accord
Collateral treatment requested by such Grantor or to take steps to preserve
rights against prior parties or property.

                  Section 11. Application of Proceeds. The proceeds of any
collection or sale of Collateral, as well as any Collateral consisting of cash,
shall be applied by the Lenders as follows:

                  FIRST, to the payment of all reasonable costs and expenses
incurred by the Lenders in connection with this Agreement or any of the
Obligations, including, but not limited to, all court costs and the reasonable
fees and expenses of the agents and legal counsel of the Lenders, the repayment
of all advances made by the Lenders hereunder on behalf of any Grantor and any
other reasonable costs or expenses incurred in connection with the exercise of
any right or remedy hereunder;

                  SECOND, to the payment in full of the principal and interest
of the Notes outstanding;

                  Each Grantor hereby waives presentment, notice of dishonor and
protest of any instruments included in or evidencing Obligations and all other
notices and demands not expressly required by this Agreement.

                  Section 15. New York Law; Resolution of Disputes. This
Agreement shall be governed by and construed in accordance with the domestic
laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other
jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of New York. Except as may be otherwise provided herein or
as the context may require, all terms used herein shall have the meaning
ascribed to them by the Uniform Commercial Code as adopted in New York. In
connection with any dispute which may arise under this Agreement, each Grantor,
for itself and in respect of its property, hereby irrevocably submits to,
consents to, and waives any objection to, the jurisdiction of the courts of the
State of New York located in the Borough of Manhattan in the City of New York or
of the United States District Court for the Southern District of New York, or,
at the option of the Lender, to the courts of any jurisdiction in which such
Grantor or any Collateral may be located, and waives any objection to the laying
of venue in such a court. Each Grantor admits that any such dispute may be
resolved at least as conveniently in such a court as in any other court and,
will not seek dismissal or a change of venue on the ground that resolution of
such a dispute in any such court is not convenient or in the interests of
justice. No Grantor shall seek a jury trial in any action based upon or arising
out of this Agreement or any related document or agreement. No Grantor will seek
to consolidate any such action with any other action in which trial by jury has
not been waived.


<PAGE>   14
                  Section 16. Waiver; Amendment. None of the terms and
conditions of this Agreement may be changed, waived, modified or varied in any
manner whatsoever without the written approval of each party hereto.

                  Section 17. Termination, Release of Collateral. After the
Termination Date (as defined below) this Agreement shall terminate and the
Lenders, at the request and expense of Grantors, will execute and deliver to
Grantors a proper instrument or instruments (including Uniform Commercial Code
termination statements on form UCC-3) acknowledging the satisfaction and
termination of this Agreement as to Grantors, and will duly assign, transfer and
deliver to Grantor (without recourse and without any representation or warranty)
such of the Collateral as may be in the possession of the Lenders and as has not
theretofore been sold or otherwise applied or released pursuant to this
Agreement. As used in this Agreement, "Termination Date" shall mean the date
upon which all payment Obligations have been irrevocably satisfied in full.

                  Section 18. Counterparts. This Agreement may be executed in
any number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same instrument. A
complete set of counterparts executed by all the parties hereto shall be lodged
with each Grantor and each Lender.

                  Section 19. Other Provisions. This Agreement constitutes the
entire agreement of the parties with respect to the subject matter hereof. It
sets forth all representations relied upon by Grantors in connection with it.
The Lenders, and their respective directors, officers, limited partners, general
partners, attorneys, agents and employees, shall not be liable to Grantors for
any loss or damage caused by any act or omission on the part of any of them
unless such loss or damage shall have been caused by the gross negligence or
wilful misconduct of such Person. This Agreement shall be binding upon the
successors and assigns of Grantors and shall inure to the benefit of the
successors of the Lenders. In the event any one or more of the provisions
contained in this Agreement should be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
contained shall not be affected or impaired in any way. Section headings used
herein are for convenience only and shall not affect the construction of this
Agreement.

                                PLEDGE AGREEMENT


                  PLEDGE AGREEMENT, dated as of May 20, 1998 among Skyline
Multimedia Entertainment, Inc., a New York corporation ("Pledgor"), and Bank of
New York, as Trustee for the Employees Retirement Plan of Keyspan Energy Corp.
("KEP") and Prospect Street NYC Discovery Fund, L.P. ("Prospect Street") (KEP
and Prospect Street collectively, the "Pledgees").

                  WHEREAS, Pledgor is the holder of all the issued and
outstanding capital stock (the "Stock") of New York Skyline, Inc., a New York
corporation ("NYSI"), Skyline Virtual Reality, Inc., a Delaware corporation
("SVR"), Skyline Chicago, Inc., a Delaware corporation ("SCI"), Skyline Magic,
Inc., a Delaware corporation ("SMI"), and Skyline Las Vegas, Inc., a Delaware
corporation ("SLVI") (SMEI, NYSI, SVR, SCI, SMI and SLVI, each a "Subsidiary,"
and collectively the "Subsidiaries").

                  WHEREAS, Pledgor and the Subsidiaries have entered into a
Senior Secured Credit Agreement with the Pledgees, dated as of May 20, 1998 (the
"Credit Agreement"); and

                  WHEREAS, in order to induce the Pledgees to enter into the
Credit Agreement, Pledgor has agreed to pledge and grant a security interest in
the Stock of each of the Subsidiaries to the Pledgees to secure the prompt and
complete payment when due and performance by Pledgor of its obligations under
the Credit Agreement;

                  NOW, THEREFORE, in consideration of the premises herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Pledgor hereby agrees with Pledgees as follows:

                  1. Pledge. Pledgor hereby pledges, assigns, hypothecates,
transfers and delivers to the Pledgees, and grants to the Pledgees a first lien
on and first priority security interest in the Stock of each of the Subsidiaries
and any and all proceeds thereof (together with any securities and other
property referred to in Section 4 hereof, the "Pledged Shares"), as collateral
security for (i) the prompt and complete payment when due (whether at the stated
maturity, by acceleration or otherwise) and performance of its obligations and
liabilities under, arising out of or in connection with the Credit Agreement and
(ii) the due and punctual payment and performance by Pledgor of its obligations
and liabilities under, arising out of or in connection with this Agreement
(collectively, the "Liabilities").

                  The obligations hereunder shall not be affected, impaired or
discharged, in whole or in part, by virtue of the illegality, invalidity or
unenforceability of any aspect of the Credit Agreement, or by any modification
of the terms of the Credit Agreement (including without limitation payment
amounts and terms). Pledgor is herewith delivering
<PAGE>   2
to the Pledgees the certificates representing the Pledged Shares registered in
the name of Pledgor, together with undated stock powers executed in blank. Such
certificates represent all the shares of each Subsidiary issued and outstanding
as of the date hereof. There are no warrants, options or other rights to acquire
shares of the capital stock of any Subsidiary, and no agreements by any
Subsidiaries to issue additional shares of its capital stock.

                  2. Inducing Representations of Pledgor. The Pledgor
acknowledges and agrees that the representations and warranties made by Pledgor
in the Credit Agreement constitute an inducement for the Pledgees to enter into
the Credit Agreement and this Agreement.

                  3. Covenants. Pledgor covenants and agrees as follows:

                           (a) Pledgor covenants and agrees that it will defend
the Pledgees' right, title and security interest in and to the Pledged Shares
and the proceeds thereof against the claims and demands of all persons
whomsoever.

                           (b) Pledgor shall not make or permit any changes to
the certificate of incorporation or by-laws of any Subsidiary and shall enter
into no agreements affecting or relating to the Pledged Shares.

                           (c) Pledgor shall not permit any Subsidiary to issue
or agree to issue any additional shares of its capital stock, or grant any
options, warrants or other rights to acquire shares of its capital stock.

                  4. Dividends, Distributions, etc. If, while this Agreement is
in effect, Pledgor shall become entitled to receive or shall receive any rights
or securities, whether as an addition to, in substitution for, or in exchange
for the Pledged Shares, or otherwise, Pledgor agrees to accept the same as agent
for the Pledgees and to hold the same in trust for the Pledgees and to deliver
the same forthwith to the Pledgees in the exact form received, with the
endorsement of Pledgor when necessary and appropriate and undated stock powers
duly executed in blank, to be held by the Pledgees, subject to the terms hereof,
as additional security for the Liabilities, and the securities represented by
such certificates shall become part of the "Pledged Shares" for all purposes of
this Agreement. In case any dividends are paid in respect of the Pledged Shares
or any property shall be distributed upon or with respect to the Pledged Shares
for any reason whatsoever, the property so distributed shall be delivered to the
Pledgees, to be held by the Pledgees as collateral security for the Liabilities.
All sums of money and property so paid or distributed in respect of the Pledged
Shares which are received by Pledgor shall, until paid or delivered to the
Pledgees, be held by Pledgor in trust as security for the Liabilities.

                  5. Administration of Security. The following provisions shall
govern the administration of the Pledged Shares:
<PAGE>   3
                           (a) Pledgor may not take any action with respect to
the Pledged Shares without the prior written consent of the Pledgees.

                           (b) Irrevocable Proxy. Pledgor hereby grants to
Pledgees an irrevocable proxy to file proofs of claim and vote or consent in
connection with the Pledged Shares (and is herewith executing and delivering to
Pledgor an Irrevocable Proxy to such effect) upon the occurrence of an Event of
Default under the Credit Agreement. Upon the request of the Pledgees, Pledgor
agrees to deliver to the Pledgees such further evidence of such irrevocable
proxy or such further irrevocable proxies with respect to the foregoing as the
Pledgees may request.

                           (c) Subject to any sale by the Pledgees or other
disposition by the Pledgees of the Pledged Shares or other property pursuant to
this Agreement, the Pledged Shares and any other property then held as part of
the Pledged Shares in accordance with the provisions of this Agreement shall be
delivered to Pledgor, upon full payment, satisfaction and termination of all of
the Liabilities and the termination pursuant to Section 16 hereof of the lien
and security interest hereby granted.

                  6. Certain Rights of the Pledgees. (a) The Pledgees shall not
be liable for failure to collect or realize upon the Liabilities, or any part
thereof, or for any delay in so doing, nor shall the Pledgees be under any
obligation to take any action whatsoever with regard thereto.

                           (b) The Pledged Shares held by the Pledgees hereunder
may, if an Event of Default has occurred and is continuing, without notice, be
registered in the name of the Pledgees or its nominee, which may thereafter
without notice exercise all rights, privileges or options pertaining to the
Pledged Shares as if it were the absolute owner thereof, including without
limitation, the right to exchange at its discretion the Pledged Shares, or any
portion thereof, upon the exercise by the Pledgees of any right, privilege or
option pertaining to the Pledged Shares, and in connection therewith, to deposit
and deliver the Pledged Shares with any committee, depositary, transfer agent,
registrar or other designated agency upon such terms and conditions as the
Pledgees may determine, all without liability except to account for property
actually received by the Pledgees but the Pledgees shall have no duty to
exercise any of the aforesaid rights, privileges or options and shall not be
responsible for any failure to do so or delay in so doing.

                  7. Remedies. (a) Upon the occurrence of an Event of Default
under the Credit Agreement, the Pledgees without demand of performance or other
demand, advertisement or notice of any kind (except the notice specified below
of the time and place of public or private sale) to or upon Pledgor or any other
person (all and each of which demands, advertisements and/or notices are hereby
expressly waived), may forthwith collect, receive, appropriate and realize upon
the Pledged Shares or any portion thereof, and/or may forthwith sell, assign,
give option or options to purchase, contract to sell or otherwise dispose of and
deliver said Pledged Shares, or any portion thereof, in one
<PAGE>   4
or more portions at public or private sale or sales, at any exchange, broker's
board or at any of the Pledgees' offices or elsewhere upon such terms and
conditions as the Pledgees may deem advisable and at such prices as the Pledgees
may deem best, for cash or on credit or for future delivery without assumption
of any credit or risk, with the right to the Pledgees upon any such sale or
sales, public or private, to purchase the whole or any portion of said Pledged
Shares so sold, free of any right or equity of redemption in Pledgor, which
right or equity is hereby expressly waived or released.

                           (b) The Pledgees shall apply the net proceeds of any
such collection, recovery, receipt, appropriation, realization or sale, after
deducting all reasonable costs and expenses of every kind incurred therein or
incidental to the safekeeping or otherwise of the Pledged Shares or any portion
thereof, in any way relating to the rights of the Pledgees hereunder, including
reasonable attorneys' fees and legal expenses, to the payment, in whole or in
part, of the Liabilities in such order as the Pledgees may elect, and only after
so paying over such net proceeds and after the payment by the Pledgees of any
amount required by any provision of law, including, without limitation, the
Uniform Commercial Code of the State of New York (the "UCC"), need the Pledgees'
accounts for the surplus, if any, to Pledgor.

                           (c) Pledgor agrees that the Pledgees shall not be
obligated to give more than thirty (30) days' notice of the time and place of
any public sale or of the time after which a private sale or other intended
disposition is to take place and that such notice shall be reasonable
notification of such matters. No notification need be given to Pledgor if it has
signed after default a statement renouncing or modifying any right to
notification of sale or other intended disposition.

                           (d) In addition to the rights and remedies granted to
the Pledgees in this Agreement and in any other instrument or agreement
securing, evidencing or relating to any of the Liabilities, the Pledgees shall
have all the rights and remedies of a secured party under the UCC. Pledgor
further agrees to waive and agrees not to assert any rights or privileges which
it may acquire under the UCC, and Pledgor shall be liable for any deficiency if
the proceeds of any sale or other disposition of the Pledged Shares are
insufficient to pay all amounts to which the Pledgees are entitled, and the
reasonable fees and expenses of any attorneys retained by the Pledgees to
collect such deficiency.

                  8. No Disposition, etc. Without the prior written consent of
the Pledgees, Pledgor agrees that it will not sell, assign, transfer, exchange,
or otherwise dispose of, or grant any option with respect to, the Pledged
Shares, or any portion thereof, nor will it create, incur or permit to exist any
pledge, lien, mortgage, hypothecation, security interest, charge, option or any
other encumbrance with respect to the Pledged Shares, or portion thereof,
interest therein, or any proceeds thereof.

                  9. Sale of Pledged Shares. (a) Pledgor recognizes that the
Pledgees may be unable to effect a public sale of the Pledged Shares by reason
of certain prohibitions contained in the Securities Act of 1933, as amended (the
"Act"), and
<PAGE>   5
applicable state securities laws, but may be compelled to resort to one or more
private sales of portions of the Pledged Shares to a restricted group of
purchasers who will be obliged to agree, among other things, to acquire such
securities for their own account for investment and not with a view to the
distribution or resale thereof.

                           (b) Pledgor further agrees to do or cause to be done
all such other acts and things as may be necessary to make such sale or sales of
the Pledged Shares or any portion thereof valid and binding and in compliance
with any and all applicable laws, regulations, orders, writs, injunctions,
decrees or awards of any and all courts, arbitrators or governmental
instrumentalities, domestic or foreign, having jurisdiction over any such sale
or sales, all at Pledgor's expense, provided that Pledgor shall be under no
obligation to take any action to enable the Pledged Shares or any portion
thereof to be registered under the provisions of the Act.

                  Pledgor further agrees that a breach of any of the covenants
contained in this Section 9 will cause irreparable injury to the Pledgees, that
the Pledgees have no adequate remedy at law in respect of such breach and, as a
consequence, agrees that each and every covenant contained in this Section 9
shall be specifically enforceable against Pledgor, and Pledgor hereby waives and
agrees not to assert any defenses to an action for specific performance of such
covenants except for a defense that no Event of Default has occurred and is
continuing under the Credit Agreement.

                  10. Indemnification and Reimbursement. (a) Pledgor agrees to
indemnify the Pledgees and their respective partners, stockholders, directors,
officers, employees, agents and affiliates (jointly and severally, the
"Indemnitees") against, hold them harmless of and from, and to the extent paid
by any Indemnitees reimburse them for, any and all loss, liability, cost, damage
and expense, including, without limitation, reasonable attorneys' fees and
expenses, which the Indemnitees may suffer or incur by reason of any action,
claim or proceeding brought by or against any Indemnitee or in which any
Indemnitee may become involved (as a plaintiff, defendant, nonparty or in any
other capacity, including without limitation in any action brought in
interpleader or against Pledgor) or in connection with any investigation,
whether conducted by an Indemnitee or another, arising out of or relating
directly or indirectly in any way to the Pledged Shares, this Agreement or any
transaction to which the Pledged Shares or this Agreement directly or indirectly
relates.

                           (b) If the indemnification provided for in paragraph
(a) of this Section 10 is for any reason held to be unavailable, Pledgor shall
contribute such amounts as are just and equitable to pay the Indemnitees or to
reimburse them for the aggregate of any and all losses, liabilities, costs,
damages and expenses, including, without limitation, reasonable attorneys' fees
and expenses, incurred by the Indemnitees as a result of or in connection with,
any amount paid in settlement of any action, claim or proceeding arising out of
or relating directly or indirectly in any way to the Pledged Shares or this
Agreement or any transaction to which the Pledged Shares or this Agreement
directly or indirectly relates. The provisions of this Section 10 shall survive
any termination of this Agreement.

<PAGE>   6
                  11. Further Assurances; Expenses. (a) Pledgor agrees that at
any time and from time to time upon the written request of the Pledgees, Pledgor
will execute and deliver such further documents and do such further acts and
things as the Pledgees may reasonably request consistent with the provisions
hereof in order to effect the intent and purposes of this Agreement.

                           (b)  Pledgor shall promptly pay on demand all
expenses, including reasonable attorneys' fees and disbursements, of the
Pledgees in connection with the administration or enforcement of this Agreement
or any other matter arising out of this Agreement.

                  12. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  13. No Waiver; Cumulative Remedies. The Pledgees shall not by
any act, delay, omission or otherwise be deemed to have waived any of its
remedies hereunder, and no waiver by the Pledgees shall be valid unless in
writing and signed by the Pledgees and then only to the extent therein set
forth. A waiver by the Pledgees of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the
Pledgees would otherwise have on any further occasion. No failure to exercise,
nor any delay in exercising on the part of the Pledgees, any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
right, power or privilege. The rights and remedies herein provided are
cumulative and may be exercised singly or concurrently, and are not exclusive of
any rights or remedies provided by law.

                  14. Successors. This Agreement and all obligations of Pledgor
hereunder shall be binding on and enforceable against the permitted successors
and assigns of Pledgor, including, without limitation, any trustee in bankruptcy
or any other successor by operation of law, and shall, together with the rights
and remedies of the Pledgees hereunder, inure to the benefit of the Pledgees.
Without limiting the generality of the foregoing sentence, all rights and powers
granted hereby to the Pledgees, or any agent or representative of the Pledgees,
may be exercised by any successor or assignee or any agent or representative of
such successor or assignee.

                  15. Applicable Law. This Agreement shall be governed by, and
construed and enforced in accordance with, the internal laws of the State of New
York without regard to its conflicts of law rules.

                  16. Termination.  This Agreement and the lien and security
interest granted hereunder shall not terminate until the full and complete
performance and
<PAGE>   7
satisfaction of all the Liabilities.

                  17. Amendment. This Agreement may not be modified or amended
except in a writing signed by Pledgor and the Pledgees.

         NOW THEREFORE, for good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the Separation Agreement is hereby
amended and restated in its entirety to read as follows:

         A.       As consideration for entering into this Agreement and the
                  terms and conditions set forth herein, I have been offered:

                  (i) as payment in connection with the purchase by the Company

                  $206,250 payable as follows: (1) $154,687.50 upon execution of
                  this Agreement, and (2) $51,562.50, of which amount I
                  acknowledge receipt of $21,654, and the balance of which is to
                  be paid bi-weekly at the rate of $3,750 commencing on the date
                  hereof until fully paid. Additionally, the Company agrees to
                  forgive amounts previously agreed to be refunded by me to the
                  Company in the amount of $750,000;

                  (ii) as payment in connection with the purchase by Prospect
                  Street of the securities referenced in Section B(V) hereof,
                  the aggregate amount of $100, which amount represents fair
                  value for such securities in light of the pledge related
                  thereto, and in consideration of Prospect Street and BUG
                  providing certain financing for the Company; and

                  (iii) the opportunity to continue to receive the
                  Company-subsidized health benefits I was receiving on the last
                  active day of my employment through the period ending on
                  January 15, 1999 or, at the Company's option, to receive the
                  economic equivalent thereof.

                  After consultation with my own counsel, I understand that
                  these payments and benefits exceed any payment, benefit, or
                  other thing of value that I might otherwise be
<PAGE>   2
                  entitled to under any Company policy, plan or procedure.

         B. In consideration of the compensation and benefits to be received by
me pursuant to paragraph A hereof, I hereby:

                           games or theater-based attractions;

                  (iii)    agree that all options and warrants previously issued
                           to me by the Company are deemed canceled as of April
                           15, 1998 and to submit to the Company all such

                  (iv)     grant to Prospect Street an irrevocable proxy coupled
                           with interest to vote all of the shares of capital

                FOR VALUE RECEIVED, Skyline Multimedia Entertainment, Inc., a
New York corporation (the "Company"), New York Skyline, Inc., a New York
corporation ("NYSI"), Skyline Virtual Reality, Inc., a Delaware corporation
("SVR"), Skyline Chicago, Inc., a Delaware corporation ("SCI"), Skyline Magic,
Inc., a Delaware corporation ("SMI") and Skyline Las Vegas, Inc., a Delaware
corporation ("SLVI"), hereby promise to pay to Bank of New York, as Trustee for
the Employees Retirement Plan of Keyspan Energy Corp., or its registered
successors or assigns (the "Registered Holder"), Five Hundred Thousand U.S.
Dollars ($500,000.00) on demand given on or after July 15, 1998 (the date of
such demand referred to herein as the "Maturity Date") in accordance with the
provisions of this Note. This Note is issued by the Company pursuant to the
Senior Secured Credit Agreement, dated as of May 20, 1998 (as such agreement may
be amended, modified or restated from time to time, the "Credit Agreement"), by
<PAGE>   2
and among the Company, the Company's subsidiaries, the Registered Holder and
Prospect Street NYC Discovery Fund, L.P. This Note is secured by the collateral
pledged to the Registered Holder pursuant to the Collateral Documents (as
defined herein). All capitalized terms used and not defined herein shall have
the meaning ascribed to such terms in the Credit Agreement.

                 "Collateral Documents" means the Security Agreement, the
Subordination Agreement, the Subsidiary Stock Pledge Agreement, the Subsidiary
Guarantee, and the Indemnity, Subrogation and Contribution Agreement (in each
case, as the same may be amended, modified or restated from time to time), and
all certificates, schedules, exhibits and other documents required to be
delivered in connection with such agreements.

                1. Interest. Interest will accrue on the unpaid principal amount
of this Note from the date hereof at a rate of 14% per annum; provided, however,
that, upon an Event of Default under Section 7.1 of the Credit Agreement, the
rate of interest shall increase to a rate per annum of 21%. Interest accrued on
this Note shall be payable on the earlier of (a) the Maturity Date, and (b) the
date of consummation of an Equity Financing. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

                2. Method of Payment. The Company will pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. The Company shall pay principal
and interest on this Note by wire transfer of immediately available funds to the
account specified by the Registered Holder in a written notice to the Company
delivered at least three Business Days prior to such payment date. If a payment
date is other than a Business Day, payment shall be made on the next succeeding
Business Day. All payments shall be applied first, to all accrued and unpaid
interest hereon, and second, to principal.

                3. Prepayment. At its option, the Company may, from time to
time, prepay all or any portion of the principal amount of this Note in cash.
Written notice of prepayment under this Section 3 shall be given to the
Registered Holder at least 5 days but not more than 30 days before the
prepayment date set forth in such notice at the address provided in or pursuant
to Section 9 herein. Any such prepayment shall be in an amount of at least
$100,000 and in integrals of $10,000, or such lesser amount as equals the then
outstanding principal amount of this Note being prepaid, and shall be
accompanied by the cash payment of all accrued and unpaid interest on the
portion of the principal then being prepaid. Once due notice of prepayment is
given, a portion of the principal amount of this Note (in such amount as the
notice states shall be prepaid) shall become due and payable on the optional
prepayment date.

                4. Repayment. The Company will repay this Note in full, in cash
on the Maturity Date at 100% of the then outstanding principal amount of this
Note plus accrued but unpaid interest thereon to such date.

                5. Optional Conversion. In the event that an Equity Financing
has been consummated prior to July 15, 1998, the holders of this Note may, at
their option, convert all, but not less than all, of the principal amount of
this Note such that each $1.00 of principal
                              
<PAGE>   3
amount of this Note shall convert into that number of units of securities
offered in such Equity Financing as are purchaseable for $1.25. Upon such
conversion, accrued and unpaid interest hereon shall be immediately payable to
the Registered Holder in cash.

                6. Events of Default; Remedies. Events of Default and the
consequences of Events of Default are set forth in Article VII of the Credit
Agreement. All provisions of Article VII of the Credit Agreement are
specifically hereby incorporated herein in full by this reference.

                7. Note Exchangeable for Different Denominations. This Note is
exchangeable, upon the surrender hereof by the Registered Holder at the
principal office of the Company, without expense to the Registered Holder, for a
Note or Notes, dated as of the date to which interest has been paid on the
unpaid principal amount of the Note or Notes so exchanged, or, if no interest
has been paid thereon, then dated as of the date of the Note or Notes so
exchanged, each in the principal amount of $250,000, or any multiple thereof (or
in any such lesser amount as shall equal the then unpaid principal amount of the
Note or Notes so exchanged), for the same aggregate unpaid principal amount as
the Note or Notes so surrendered for exchange and each payable to such Person or
Persons, or order, as may be designated by such Registered Holder (subject to
Section 15 herein); provided, however, that upon any such exchange there shall
be filed with the Company the name and address for all purposes hereof of the
payee of each Note delivered in the exchange for this Note and such exchanged
Note shall in all other respects be in the same form and have the same terms as
this Note.

                8. Replacement. Upon receipt of evidence reasonably satisfactory
to the Company (an affidavit of the Registered Holder shall be satisfactory) of
the ownership and the loss, theft, destruction or mutilation of this Note, and
in the case of any such loss, theft or destruction, upon receipt of indemnity
reasonably satisfactory to the Company (provided that if the Registered Holder
is a financial institution or other institutional investor its own sworn or
notarized agreement shall be satisfactory) or, in the case of any such
mutilation upon surrender of this Note, the Company shall (at its expense)
execute and deliver in lieu of such Note, a Note of like kind representing the
same rights represented by such lost, stolen, destroyed or mutilated Note and
dated as of the date to which interest has been paid on the unpaid principal
amount of the Note so lost, stolen, destroyed or mutilated, or, if no interest
has been paid thereon, then dated as of the date of the Note so lost, stolen,
destroyed or mutilated.

                9. Securities Act. This Note has not been registered under the
Securities Act of 1933 and applicable state securities laws. Therefore, the
Company may require, as a condition of allowing the transfer or exchange of this
Note, that the Registered Holder furnish to the Company an opinion of counsel
reasonably acceptable to the Company to the effect that such transaction is
allowable under the Securities Act of 1933 and applicable state securities laws.

                10. Notices. All notices, requests and other communications
hereunder must be in writing and will be deemed to have been duly given only if

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS, AND MAY

                          COMMON STOCK PURCHASE WARRANT


                           Date of Issuance: _______ ___, 1998 Certificate No. 1


         For value received, SKYLINE MULTIMEDIA ENTERTAINMENT, INC., a New York
corporation (the "Company"), hereby grants to Bank of New York as Trustee for
the Employees Retirement Plan of Keyspan Energy Corp. and or its registered
assigns (the "Registered Holder"), the right to purchase from the Company,
subject to the terms and conditions herein contained that number of shares of
common stock par value $.001 of the Company (the "Warrant Shares") as set forth
in Section 1A hereof, at a price per share of $.375 (the "Exercise Price"). This
Warrant is issued pursuant to the Senior Secured Credit Agreement dated as of
May 20, 1998, by and among the Company, the other Borrowers named therein and
the Lenders named therein (as such agreement may be amended, modified or
restated from time to time, the "Credit Agreement"). Certain capitalized terms
used herein are defined in Section 2 hereof. All other capitalized terms used
and not defined herein shall have the meaning ascribed to such terms in the
Credit Agreement.

         This Warrant is subject to the following provisions:

         SECTION 1.        Exercise of Warrant.

         1A. Exercise Period. The purchase rights represented by this
Warrant may be exercised only upon the happening of the following events and for
the amount of shares stated:

                  (i)      In the event the entire principal amount of the Notes
                           (plus all accrued and unpaid interest thereon) is
                           repaid prior to July 15, 1998, then this Warrant
                           shall be exerciseable into such number of shares of
                           Common Stock that equals 32% of such Common Stock on
                           a Fully Diluted Basis on the date of such issuance;
                           or

                  (ii)     In the event the entire principal amount of the Notes
                           has not been repaid (plus all accrued and unpaid
                           interest thereon) or converted (pursuant to the
                           terms of the Notes) prior to July 15, 1998, then this
                           Warrant shall be
<PAGE>   2
                           exercisable into such number of shares of Common
                           Stock that equal 47.167% of the Common Stock on a
                           Fully Diluted Basis at the time of issuance. Upon
                           consummation of an Equity Financing and repayment or
                           conversion of the entire principal amount of the 
                           Notes (plus all accrued and unpaid interest
                           thereon) before July 15, 1998, this Warrant shall be
                           cancelled and of no further force and effect.

         1B.      Exercise Procedure.

                  (i) This Warrant shall be deemed to have been exercised when
all of the following items have been delivered to the Company (the "Exercise
Time"):

                           (a)      a completed Exercise Agreement, as described
in Section 1C below, executed by the Person exercising all or part of the
purchase rights represented by this Warrant (the "Purchaser");

                           (b)      this Warrant;

                           (c)      if the Purchaser is not the Registered
Holder, an Assignment or Assignments in the form set forth in Exhibit II hereto
evidencing the assignment of this Warrant to the Purchaser; and

                           (d)      either (i) a check payable to the Company in
an amount equal to the Exercise Price multiplied by the number of Warrant Shares
being purchased upon such exercise (the "Aggregate Exercise Price"), (ii) the
surrender to the Company of debt or equity securities of the Company or any of
its direct or indirect subsidiaries having a value equal to the Aggregate
Exercise Price of the Warrant Shares being purchased upon such exercise (which
value in the case of debt securities or any preferred stock shall be deemed to
equal the aggregate outstanding principal amount or liquidation value thereof
plus all accrued and unpaid interest thereon or accrued or declared and unpaid
dividends thereon and in the case of shares of Common Stock shall be the Fair
Market Value thereof), or (iii) the delivery of a notice to the Company that the
Purchaser is exercising the Warrant (or portion thereof) by authorizing the
Company to reduce the number of Warrant Shares subject to such exercise of the
Warrant or portion thereof by the number of shares having an aggregate Fair
Market Value determined as of the date immediately prior to the date of the
Exercise Time equal to the Aggregate Exercise Price.

                  (ii) Certificates for Warrant Shares purchased upon exercise
of this Warrant shall be delivered by the Company to the Purchaser within five
days after the date of the Exercise Time.

                  (iii) The Warrant Shares issuable upon the exercise of this
Warrant shall be deemed to have been issued to the Purchaser at the Exercise
Time, and the Purchaser shall be deemed for all purposes to have become the
Registered Holder of such Warrant Shares at the Exercise Time.
<PAGE>   3
                  (iv) The issuance of certificates for Warrant Shares upon
exercise of this Warrant shall be made without charge to the Registered Holder
or the Purchaser for any issuance tax in respect thereof or other cost incurred
by the Company in connection with such exercise and the related issuance of
Warrant Shares; provided, however, that the Company shall not be required to pay
any tax or taxes which may be payable in respect of any transfer involved in the
issuance of any Warrants or any certificates representing Warrant Shares in a
name other than that of a Registered Holder, and the Company shall not be
required to issue or deliver such Warrant or certificate for Warrant Shares
unless and until the Person requesting the issuance thereof shall have paid to
the Company the amount of such tax or shall have established to the reasonable
satisfaction of the Company that such tax has been paid.

                  (v) The Company shall not close its books against the transfer
of this Warrant or of any Warrant Shares issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant.

                  (vi) The Company shall assist and cooperate with any
reasonable request by the Registered Holder or Purchaser in connection with any
governmental filings or approvals required to be obtained or made by any of them
prior to or in connection with any exercise of this Warrant (including, without
limitation, making any filings or obtaining any approvals required to be made or
obtained by the Company).

                  (vii) The Company shall at all times reserve and keep
available out of its authorized but unissued Warrant Shares solely for the
purpose of issuance upon the exercise of this Warrant, the maximum number of
Warrant Shares issuable upon the exercise of this Warrant, or, if such unissued
Warrant Shares are insufficient to comply with such reserve requirement, the
Company shall use its best efforts to increase the authorized capital stock of
the Company in an amount sufficient to comply herewith and submit such proposal
for approval by the Company's shareholders at the next annual meeting of
shareholders of the Company. All Warrant Shares which are so issuable shall,
when issued and upon the payment of the applicable Exercise Price, be duly and
validly issued, fully paid and nonassessable and free from all taxes, liens and
charges. The Company shall take all such actions as may be necessary to ensure
that all such Warrant Shares may be so issued without violation by the Company
of any applicable law of governmental regulation or any requirements of any
domestic securities exchange upon which shares of Common Stock or other
securities constituting Warrant Shares may be listed (except for official notice
of issuance which shall be immediately delivered by the Company upon each such
issuance). The Company will cause the Warrant Shares, immediately upon such
exercise, to be listed on any domestic securities exchange upon which shares of
Common Stock or other securities constituting Warrant Shares are listed at the
time of such exercise.

                  1C. Exercise Agreement. Upon any exercise of this Warrant, the
Purchaser shall deliver to the Company an Exercise Agreement in substantially
the form set forth in Exhibit I hereto, except that if the Warrant Shares are
not to be issued in the name of the Registered Holder, the Exercise Agreement
shall also state the name of the Person to whom the certificates for the Warrant
Shares are to be issued, and if the number of Warrant Shares to be issued does
not include all of the Warrant Shares purchasable hereunder, it shall also state
the name of the
<PAGE>   4
Person to whom a new Warrant for the unexercised portion of the rights hereunder
is to be issued.

         SECTION 2.        Definitions.  The following terms have the meanings
set forth below:

         "Common Stock" means the common stock, par value $.001 per share and
the Class A common stock, par value $.001 per share (the "Class A Common
Stock"), of the Company, any securities into which such common stock shall have
been changed or any securities resulting from any reclassification or
recapitalization of such common stock and Class A Common Stock, and all other
securities of any class or classes (however designated) of the Company the
holders of which have the right, without limitation as to amount, after payment
on any securities entitled to a preference on dividends or other distributions
upon any dissolution or winding up, either to all or to a share of the balance
of payments upon such dissolution, liquidation or winding up.

         "Equity Financing " has the meaning ascribed thereto in the Credit
Agreement.

         "Fair Market Value" means (i) the average of the closing sales prices
of the Common Stock on all domestic securities exchanges on which the Common
Stock is listed, or (ii) if there 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, (iii) if on any day the Common Stock is not
so listed, the sales price for the Common Stock as of 4:00 P.M., New York time,
as reported on the Nasdaq Stock Market or, (iv) if the Common Stock is not
reported on the Nasdaq Stock Market, the average of the representative bid and
asked quotations for the Common Stock as of 4:00 P.M., New York time, as
reported on the Nasdaq interdealer quotation system, or any similar successor
organization, in each such case averaged over a period of 21 trading days
consisting of the day as of which "Fair Market Value" is being determined and
the immediately prior 20 trading days prior to such day during which the Common
Stock was traded. Notwithstanding the foregoing, if at any time of determination
either (x) the Common Stock is not registered pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended, and then listed on a national
securities exchange or authorized for quotation in the Nasdaq system, or (y)
less than 25% of the outstanding Common Stock is held by the public free of
transfer restrictions under the Securities Act of 1933, as amended, then Fair
Market Value shall mean the price that would be paid per share for the entire
common equity interest in the Company in an orderly sale transaction between a
willing buyer and a willing seller, using valuation techniques then prevailing
in the securities industry, and assuming full disclosure of all relevant
information and a reasonable period of time for effectuating such sale, without
discount for lack of liquidity, or minority position. Fair Market Value shall be
determined jointly by the Company's Board of Directors in its good faith
judgment and the Required Holders; provided that, if such parties are unable to
so agree within 15 days, such value shall be determined by an independent
investment banking or appraisal firm mutually acceptable to the Company and the
Required Holders, which firm shall submit to the Company and the Warrant holders
a written report setting forth such determination. The fees and expenses of such
firm will be borne by the Company, and the determination of such firm will be
final and binding upon all parties.

         "Fully Diluted Basis" means, with respect to the calculation of the
number of shares of
<PAGE>   5
Common Stock, all shares of Common Stock outstanding at the time of
determination and all shares issuable upon the exercise of options or
convertible or exchangeable securities or warrants (giving effect to the Warrant
Shares issuable hereunder).

         "Person" means any natural person, corporation, general partnership,
limited partnership, proprietorship, limited liability company, limited
liability partnership, other business organization, trust, union, association or
governmental or regulatory authority.

         "Required Holders" means the holders representing a majority of the
Warrants Shares issuable upon exercise of the Warrants.

         "Warrant Shares" means shares of the Company's Common Stock issued
under this Warrant; provided, that if the securities issuable upon exercise of
the Warrants are issued by an entity other than the Company or there is a change
in the class of securities so issuable, then the term "Warrant Shares" shall
mean shares of the security issuable upon exercise of the Warrants if such
security is issuable in shares, or shall mean the equivalent units in which such
security is issuable if such security is not issuable in shares.

         SECTION 3. No Voting Rights; Limitations of Liability. This Warrant
shall not entitle the Registered Holder hereof to any voting rights or other
rights as a stockholder of the Company. No provision hereof, in the absence of
affirmative action by the Register Holder to purchase Warrant Shares, and no
enumeration herein of the rights or privileges of the Registered Holder shall
give rise to any liability of such Registered Holder for the Exercise Price of
Warrant Shares acquirable by exercise hereof or as a stockholder of the Company.

         SECTION 4. Warrant Transferable. Subject to the transfer conditions
referred to in the legend endorsed hereon, this Warrant and all rights hereunder
are transferable, in whole or in part, without charge to the Registered Holder
(subject to the provisions of paragraph 1B(iv) hereof), upon surrender of this
Warrant with a properly executed Assignment (in the form of Exhibit II hereto)
at the principal office of the Company.

         SECTION 5. Warrant Exchangeable for Different Denominations. This
Warrant is exchangeable, upon the surrender hereof by the Registered Holder at
the principal office of the Company, for new Warrants of like tenor representing
in the aggregate the purchase rights hereunder, and each of such new Warrants
shall represent such portion of such rights as is designated by the Registered
Holder at the time of such surrender. All Warrants representing portions of the
rights hereunder are referred to herein as the "Warrants."

         SECTION 6. Exchange. In the event that it becomes unlawful or, in the
reasonable judgment of any Registered Holder of this Warrant, unduly burdensome
by reason of a change in legal or regulatory considerations or the
interpretation thereof affecting such Registered Holder, or any material change
(including a reduction in the number of shares of Common Stock outstanding) in
the capital structure of the Company, to hold any or all of the Warrants or
Warrant Shares, the Registered Holder of this Warrant shall have the right to
require the Company to use its best efforts to permit all or part of such
Registered Holder's Warrants or
<PAGE>   6
Warrant Shares to be exchanged for nonvoting stock or similar interests that
convey equivalent economic benefits to such Warrants or Warrant Shares. To the
extent that the Company may lawfully do so after the exercise of its best
efforts, any such exchange shall occur as soon as practicable but in any event
within 60 days after written notice by the Registered Holder of this Warrant to
the Company (or such earlier date if required to comply with applicable law).

         SECTION 7. Replacement. Upon receipt of evidence reasonably
satisfactory to the Company (an affidavit of the Registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing this Warrant, and in the case of any such loss, theft
or destruction, upon receipt of indemnity reasonably satisfactory to the Company
(provided that if the Registered Holder is a financial institution or other
institutional investor its own agreement shall be satisfactory), or, in the case
of any such mutilation upon surrender of such certificate, the Company shall (at
its expense) execute and deliver in lieu of such certificate a new certificate
of like kind representing the same rights represented by such lost, stolen,
destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate.

         SECTION 8. Notices. Except as otherwise expressly provided herein, all
notices and deliveries referred to in this Warrant shall be in writing, shall be
delivered personally, sent by registered or certified mail, return receipt
requested and postage prepaid or sent via nationally recognized overnight
courier or via facsimile, and shall be deemed to have been given when so
delivered (or when received, if delivered by any other method) if sent (i) to
the Company, at its principal executive offices and (ii) to a Registered Holder,
at such Registered Holder's address as it appears in the records of the Company
(unless otherwise indicated by any such Registered Holder).

         SECTION 9. Amendment and Waiver. Except as otherwise provided herein,
the provisions of the Warrants may be amended and the Company may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the prior written consent of
the Required Holders.

         SECTION 10. Warrant Register. The Company shall maintain at its
principal executive offices books for the registration and the registration of
transfer of Warrants. The Company may deem and treat the Registered Holder as
the absolute owner hereof (notwithstanding any notation of ownership or other
writing thereon made by anyone) for all purposes and shall not be affected by
any notice to the contrary.

         SECTION 11. Fractions of Shares. The Company may, but shall not be
required to, issue a fraction of a Warrant Share upon the exercise of this
Warrant in whole or in part. As to any fraction of a share which the Company
elects not to issue, the Company shall make a cash payment in respect of such
fraction in an amount equal to the same fraction of the Fair Market Value of a
Warrant Share on the date of such exercise.

                  SECTION 12. Descriptive Headings; Governing Law. The
descriptive headings of the several Sections and paragraphs of this Warrant are
inserted for convenience only and do not

CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF NEW YORK WITHOUT
GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER
OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE
APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.
