            SECTION 2.1. Commitment to Purchase. Subject to the terms and
conditions set forth herein and in reliance on the representations and
warranties of the Company contained herein, the Purchaser agrees to purchase
from the Company at a purchase price of 100% of the principal amount thereof,
Notes in an aggregate principal amount not to exceed the Commitment Amount. If
any Notes are purchased, the Purchaser shall purchase on the Closing Date the
entire Initial Commitment Amount. Any subsequent purchases may be made at any
time during the Availability Period, but on no more than three separate
occasions.

            SECTION 2.2. Notice of Purchase. Except for purchases on the Closing
Date, the Company shall give the Purchaser notice not later than 10:00 a.m. on
the fifth Business Day before each issuance and sale of Notes, specifying:

            (a) the date and time of the purchase and sale of the Notes (such
      date and time, if at all, the "Time of Purchase");

            (b) the aggregate principal amount of Notes to be issued and sold to
      the Purchaser at such Time of Purchase (which amount shall be, in the case
      of purchases after the Closing Date, an integral multiple of $5,000,000

subject to the satisfaction of all terms and conditions set forth herein, the
Purchaser shall deliver, by wire transfer to the Company Account, immediately
available funds in an amount equal to the aggregate purchase price of the Notes

following amounts, which, in the case of clauses (i) and (ii) below, shall be
non-refundable and retained by Purchaser:
<PAGE>   17

                                      -12-


            (i) a takedown fee in respect of the Notes to be issued on such date
      in an amount equal to 1.00% of the aggregate principal amount thereof;

            (ii) reimbursement for all previously unreimbursed reasonable

representing the aggregate principal amount of Notes issued at such Time of
Purchase, registered in the name of the Purchaser, or, if requested by the
Purchaser, separate Notes in such other denominations and registered in such

the Company of Net Cash Proceeds from or in anticipation of a Designated
Transaction (other than a lease or sale and leaseback of computer equipment) at
a time at which no Notes are outstanding, the Commitment Amount shall be reduced
by the amount of such Net Cash Proceeds. Upon the receipt by the Company of any
such Net Cash Proceeds at a time at which Notes are outstanding, the Commitment
Amount shall be reduced by the excess, if any, of the amount of such Net Cash
Proceeds over the aggregate principal amount of all Notes then outstanding.
Notwithstanding the foregoing, the Commitment Amount shall be so reduced only to
the extent that Net Cash Proceeds from all Designated Transactions on and after
the date hereof exceed $1,000,000.

terminate on the Termination Date.

            SECTION 2.6. Prepayment of Notes. (a) The Company at its option may,

part of the principal amount of Notes at a redemption price equal to 101% (or,
if the Company shall have paid the fee required by Section 6.18(b), 100%) of
the principal amount of Notes so prepaid, together with accrued interest
through the date of prepayment; provided, 
                                                            
<PAGE>   18

                                      -13-


that the redemption price shall be 103% of par plus accrued interest if the
Notes are refunded (whether at the time of redemption or maturity) with or in
anticipation of funds raised by any financing transaction in which DLJSC has
not acted as sole agent or underwriter to the Company (unless DLJSC, in its
sole discretion, shall have consented thereto).

            (b) The Company shall, promptly upon the receipt by the Company of
the Net Cash Proceeds of any Designated Transaction, prepay an aggregate
principal amount of Notes equal to the amount of such Net Cash Proceeds, at a
redemption price equal to 101% of the principal amount of the Notes so prepaid,
together with accrued interest through the date of prepayment; provided, that
the redemption price shall be 103% of par plus accrued interest if the Notes are
refunded (whether at the time of redemption or maturity) with or in anticipation
of funds raised by any financing transaction in which DLJSC has not acted as
sole agent or underwriter to the Company (other than a fully underwritten bank
financing pursuant to a signed commitment letter containing only such conditions
as are usual and customary in such financings and which does not contain any
condition relating to the successful syndication of such transaction); and
provided, further, that Notes shall be required to be so prepaid only to the
extent that Net Cash Proceeds from all Designated Transactions on and after the
date hereof exceed $1,000,000.

            (c) The Company shall, immediately upon the occurrence of a Change
in Control, prepay all Notes then outstanding at a redemption price equal to
103% of the principal amount thereof, together with accrued interest through
the date of prepayment.                                      

            (d) Any prepayment of the Notes pursuant to Section 2.6(a) shall be
in a minimum amount of at least $1,000,000 and multiples of $1,000,000, unless
less than $1,000,000 of the Notes remains outstanding, in which case all of the
Notes must be prepaid. Any prepayment of the Notes pursuant to Section 2.6(b)
shall be in a minimum amount which is a multiple of $1,000 times the number of
Holders at the time of such prepayment.

            (e) Any partial prepayment shall be made so that the Notes then held
by each Holder shall be prepaid in a principal amount which shall bear the same
ratio, as nearly as may be, to the total principal amount being prepaid as the
principal amount of such Notes held by such Holder shall bear to the aggregate
principal amount of all Notes then outstanding. In the 
<PAGE>   19

                                      -14-


event of a partial prepayment, upon presentation of any Note the Company shall
execute and deliver to or on the order of the Holder, at the expense of the
Company, a new Note in principal amount equal to the remaining outstanding
portion of such Note.

            SECTION 2.7. Effectiveness. This Agreement shall not be effective
unless, at Closing Date, the Company delivers to the Purchaser a commitment fee
in the amount of $3,000,000 in immediately available funds to the account
specified on the signature page hereof.
                            
            SECTION 2.8. Reserve Account. Prior to the Closing Date, the Company
shall establish an account with DLJSC in Snoga Inc.'s name as escrow agent for
the Company, the Purchaser and the Holders of the Notes (the "Reserve Account").
The Company, the Purchaser and Snoga Inc., as escrow agent, shall enter into an
Interest Reserve Escrow Agreement in substantially the form of Exhibit D hereto.
The Company hereby irrevocably directs the Purchaser to deposit into the Reserve
Account from the proceeds of the issuances of Notes retained by the Purchaser in
accordance with clause (iii) of Section 2.3, on the Closing Date and on each
subsequent Time of Purchase, an interest reserve of 11.0% of the aggregate
principal amount of Notes to be issued at such Time of Purchase, not to exceed
$22,000,000 in the aggregate. The Purchaser is hereby authorized and directed
(i) to cause the Escrow Agent to invest the balances from time to time in the
Reserve Account as provided in the Interest Reserve Escrow Agreement and to
credit all interest and other income from such investment to the Reserve
Account, and (ii) to debit the balances from time to time in the Reserve Account
first, for the accrued and unpaid interest in respect of the Notes when and as
due, second, for any unpaid fees and expenses due to the Purchaser hereunder,
and thereafter, when all of the Notes have been repaid in full, to the Company.
So long as no Default or Event of Default shall have occurred and is continuing,
the balance in the Reserve Account in excess of 11.0% of the aggregate principal
amount of Notes then outstanding shall be remitted to the Company to the extent
such balance is not then required to satisfy any prepayment obligations of the
Company under Section 2.6.

such information hereafter furnished by or on behalf of the Company to the
Purchaser will not (in each case taken together and on the date as of which such

commitments of any character pursuant to which any of the Company's Subsidiaries
is required to issue any shares of its capital stock (other than to the
Company).

            SECTION 3.14. Solicitation; Access to Information. No form of
general solicitation or general advertising was used by the Company or, to the

behalf (except that the Company makes no representation as to the Purchaser and
its Affiliates) will sell or offer for sale any such security to, or solicit any

are in full force and effect, and the Company and its Subsidiaries have
fulfilled and performed all obligations with respect to such Permits; (c) no
event has occurred which allows, or after notice or lapse of time would allow,
revocation or termination by the issuer thereof or which results in any other
impairment of the rights of the holder of any such Permit; and (d) the Company
has no reason to believe that any governmental body or agency is considering
limiting, suspending or revoking any such Permit, except, in each case, to the

existing condition, situation or set of circumstances which could reasonably be
expected to result in such a liability, other than (i) those liabilities
provided for in the financial statements delivered pursuant to Section 3.5 (b)
and (ii) liabilities incurred since September 30, 1997 in the ordinary course of
the Company's business consistent with past practice.

and its Subsidiaries as presently conducted. No claim is pending or, to the
knowledge of the Company, threatened that the Company or any of its Subsidiaries
has infringed or is infringing upon the asserted rights of any other Person with
respect to any Intellectual Property. No claim is pending or, to the knowledge
of the Company, threatened that any such Intellectual Property owned or licensed

Subsidiaries otherwise has the right to use, is invalid or unenforceable.

Holders may, on behalf of all of the Holders, by written notice to the Company,
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived, except nonpayment of principal or interest that has
become due solely because of the acceleration, and if the rescission would not
conflict with any judgment or decree then in effect; provided that any uncured
monetary defaults existing other than solely because of the acceleration may be
waived only by Holders of all the Notes.

any other right or remedy, 
<PAGE>   45

                                      -40-


and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
or subsequent assertion or employment of any other appropriate right or remedy.
Every power and remedy given hereunder or by law may be exercised from time to
time, and as often as shall be deemed expedient, by the Holders.

                                   ARTICLE IX

                                COLLATERAL AGENT

            SECTION 9.1. Collateral Agent. (a) Each Holder by acceptance of a
Note appoints the Purchaser (and the Purchaser accepts appointment) as its
nominee and agent, in its name and on its behalf pursuant to the terms and
conditions of the Financing Documents to be the secured party, mortgagee,
beneficiary, recipient and similar party in respect of any collateral for the
benefit of the Holders (in such capacity, the "Collateral Agent"). If the
initial or any successor Collateral Agent ever ceases to be a party to this
Agreement or if the initial or any successor Collateral Agent ever resigns
(whether voluntarily or at the request of Majority Holders) then Majority
Holders shall appoint the successor Collateral Agent from among the Holders
(other than the resigning Collateral Agent).

            (b) The Collateral Agent, in its capacity as a Holder, has the same
rights under the Financing Documents as any other Holder and may exercise those
rights as if it were not acting as Collateral Agent; the term "Holder" shall,
unless the context otherwise indicates, include the Collateral Agent; and the
Collateral Agent's resignation or removal shall not impair or otherwise affect
any rights that it has or may have in its capacity as an individual Holder. Each
Holder and the Company agree that the Collateral Agent is not a fiduciary for
the Holders or for the Company but simply is acting in the capacity described in
this Agreement to alleviate administrative burdens for the Company and the
Holders, and that the Collateral Agent has no duties or responsibilities to the
Holders or the Company, except those expressly set forth in the Financing
Documents.

            SECTION 9.2. Limitation of Liability. Neither the Collateral Agent
nor any of its Affiliates, successors or assigns will be liable for any action
taken or omitted to be 
<PAGE>   46

                                      -41-


taken by it or them under the Financing Documents in good faith and believed by
it or them to be within the discretion or power conferred upon it or them by the
Financing Documents or be responsible for the consequences of any error in
judgment (except for fraud, gross negligence or willful misconduct), and none of
them has a fiduciary relationship with any Holder by virtue of the Financing
Documents.

            SECTION 9.3. Default; Collateral. While a Default exists, the
Holders agree to promptly confer in order that Majority Holders may agree upon a
course of action for the enforcement of the right of Holders and the Collateral
Agent is entitled to refrain from taking any action(without incurring any
liability to any Person for so refraining) unless and until it has received
instructions from Majority Holders. In actions with respect to any property of
the Company, the Collateral Agent is acting for the ratable benefit of each
Holder. The Collateral Agent shall hold, for the ratable benefit of all Holders,
any security it receives for the Secured Obligation or any guaranty of the
Secured Obligation it receives upon or in lieu of foreclosure.

            SECTION 9.4. Pledged Collateral Matters. (a) Each Holder authorizes
and directs the Collateral Agent to enter into the Collateral Documents for the
ratable benefit of the Holders and to take any action concerning any Pledged
Collateral with the consent of, or at the request of, the Majority Holders in
accordance with the provisions of the Financing Documents, and the exercise by
the Collateral Agent (with the consent of, or at the request of, the Majority
Holders) of powers concerning the Pledged Collateral set forth in any Financing
Documents, together with other reasonably incidental powers, shall be authorized
by and binding upon all Holders.

            (b) The Collateral Agent is authorized on behalf of all Holders,
without the necessity of any notice to or further consent from any Holders, from
time to time before a Default or an Event of Default, to take any action with
respect to any Pledged Collateral or Collateral Documents that may be necessary
to perfect and maintain perfected the Liens upon the Pledged Collateral granted
by the Collateral Documents.

operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy.

            (b) Any provision of this Agreement may be amended, supplemented or
waived if, but only if, such amendment, supplement or waiver is in writing and
is signed by the Company and the Majority Holders; provided, however, that
without the consent of each Holder of any Note affected thereby an amendment or
waiver may not (i) reduce the aggregate principal amount of Notes whose Holders
must consent to an amendment or waiver, (ii) reduce the rate or extend the time
for payment of interest on any Note, (iii) reduce the principal amount of or
extend the stated maturity of any Note or (iv) make any Note payable in money or
property other than as stated in such Note. In determining whether the Holders
of the requisite principal amount of Notes have concurred in any direction,
consent, or waiver as provided in any Financing Document, Notes which are owned
by the Company or any other obligor on or guarantor of the Notes, or by any
Person Controlling, Controlled by, or under common Control with any of the
foregoing, shall be disregarded and deemed not to be outstanding for the purpose
of any such determination; provided, further, however, that no such amendment,
supplement or waiver which affects the rights of the Purchaser and its
Affiliates otherwise than solely in their capacities as 
<PAGE>   48

                                      -43-


Holders of Notes shall be effective with respect to them without their prior
written consent.

            SECTION 10.3. Indemnification. The Company agrees to indemnify and
hold harmless the Purchaser, its affiliates, and each Person, if any, who
controls the Purchaser, or any of its affiliates, within the meaning of the
Securities Act or the Exchange Act (a "Controlling Person"), and their
respective partners, agents, employees, officers and directors of the Purchaser,
its affiliates and any such Controlling Person (each an "Indemnified Party" and
collectively, the "Indemnified Parties"), from and against any and all losses,
claims, damages, liabilities and expenses (including, as incurred, reasonable
costs of investigating, preparing or defending any such claim or action, whether
or not such Indemnified Party is a party thereto) relating to or arising out of,
or in connection with, any activities contemplated by any Financing Document or
any other services rendered in connection therewith, including, but not limited
to, losses, claims, damages, liabilities or expenses arising out of or based
upon any untrue statement or any alleged untrue statement of a material fact or
any omission or any alleged omission to state a material fact in any of the
disclosure or offering or confidential information documents (the "Disclosure
Documents") pertaining to any of the transactions or proposed transactions
contemplated therein, including any eventual refinancing or resale of the Notes;
provided, however, that the Company will not be responsible for any claims,
liabilities, losses, damages or expenses that are determined by final judgment
of a court of competent jurisdiction to result solely from such Indemnified
Party's gross negligence, willful misconduct or bad faith. The Company also
agrees that no Indemnified Party shall have any liability for claims,
liabilities, damages, losses or expenses, including legal fees, incurred by the
Company in connection with this Agreement unless they are determined by final
judgment of a court of competent jurisdiction to result solely from such
Indemnified Party's gross negligence, willful misconduct or bad faith.

            If any action shall be brought against an Indemnified Party with
respect to which indemnity may be sought against the Company under this
Agreement, such Indemnified Party shall promptly notify the Company in writing
and the Company shall, if requested by such Indemnified Party or if the Company
desires to do so, assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party and payment of all
reasonable fees and expenses. The failure to so notify the Company shall not
affect any obligations the Company may have to such Indemnified Party under this
<PAGE>   49

                                      -44-


Agreement or otherwise unless the Company is materially adversely affected by
such failure. Such Indemnified Party shall have the right to employ separate
counsel in such action and participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party,
unless: (i) the Company has failed to assume the defense and employ counsel
reasonably satisfactory to such Indemnified Party or (ii) the named parties to
any such action (including any impleaded parties) include such Indemnified Party
and the Company, and such Indemnified Party shall have been advised by counsel
that there may be one or more legal defenses available to it which are different
from or additional to those available to the Company, in which case, if such
Indemnified Party notifies the Company in writing that it elects to employ
separate counsel at the expense of the Company, the Company shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Party, provided, however, that the Company shall not, in connection
with any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be responsible hereunder for the
reasonable fees and expenses of more than one such firm of separate counsel, in
addition to any local counsel, which counsel shall be designated by the
Purchaser. The Company shall not be liable for any settlement of any such action
effected without the written consent of the Company (which shall not be
unreasonably withheld) and the Company agrees to indemnify and hold harmless
each Indemnified Party from and against any loss or liability by reason of
settlement of any action effected with the consent of the Company. In addition,
the Company will not, without the prior written consent of the Purchaser, settle
or compromise or consent to the entry of any judgment in or otherwise seek to
terminate any pending or threatened action, claim, suit or proceeding in respect
to which indemnification or contribution may be sought hereunder (whether or not
any Indemnified Party is a party thereto) unless such settlement, compromise,
consent or termination includes an express, unconditional release of the
Purchaser and the other Indemnified Parties, satisfactory in form and substance
to the Purchaser, from all liability arising out of such action, claim, suit or
proceeding.

            If for any reason the foregoing indemnity is unavailable to an
Indemnified Party or insufficient to hold an Indemnified Party harmless, then in
lieu of indemnifying such Indemnified Party, the Company shall contribute to the
amount paid or payable by such Indemnified Party as a result of such claims,
liabilities, losses, damages, or expenses (i) in such 
<PAGE>   50

                                      -45-


proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and by the Purchaser on the other from the transactions
contemplated by this Agreement or (ii) if the allocation provided by clause (i)
is not permitted under applicable law, in such proportion as is appropriate to
reflect not only the relative benefits received by the Company on the one hand
and the Purchaser on the other, but also the relative fault of the Company and
the Purchaser as well as any other relevant equitable considerations.
Notwithstanding the provisions of this Section 9.3, the aggregate contribution
of all Indemnified Parties shall not exceed the amount of fees actually received
by the Purchaser pursuant to this Agreement. It is hereby further agreed that
the relative benefits to the Company on the one hand and the Purchaser on the
other with respect to the transactions contemplated hereby shall be deemed to be
in the same proportion as (i) the total value of the transactions contemplated
hereby bears to (ii) the fees paid to the Purchaser with respect to the
transactions contemplated hereby. It is hereby further agreed that the relative
fault of the Company on the one hand and the Purchaser on the other with respect
to the transactions contemplated hereby shall be determined by reference to,
among other things, whether any untrue or alleged untrue statement of material
fact or the omission or alleged omission to state a material fact related to
information supplied by the Company or by the Purchaser and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

            The indemnification, contribution and expense reimbursement
obligations set forth in this Section 9.3(i) shall be in addition to any
liability the Company may have to any Indemnified Party at common law or
otherwise, (ii) shall survive the termination of this Agreement and the other
Financing Documents and the payment in full of the Notes and (iii) shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of the Purchaser or any other Indemnified Party.

            SECTION 10.4. Expenses; Documentary Taxes. The Company agrees to pay
all reasonable out-of-pocket costs, expenses and other payments in connection
with the purchase and sale of the Notes as contemplated by this Agreement,
including (i) all reasonable fees and disbursements of special counsel for the
Purchaser incurred in connection with the preparation of the 
<PAGE>   51

                                      -46-


Financing Documents, (ii) all reasonable out-of-pocket expenses of the
Purchaser, including fees and disbursements of counsel, in connection with any
waiver or consent hereunder or under any other Financing Document or any
amendment hereof or thereof and (iii) all out-of-pocket expenses of the
Purchaser and each Holder, including fees and disbursements of counsel, in
connection with any collection, bankruptcy, insolvency and other enforcement
proceedings resulting therefrom. In addition, the Company agrees to pay any and
all stamp, transfer and other similar taxes, assessments or charges payable in
connection with the execution and delivery of any Financing Document or the
issuance of Notes (other than any Note issued in a Transfer).

            SECTION 10.5. Payment. The Company agrees that, so long as the
Purchaser shall own any Notes purchased by it from the Company hereunder, the
Company will make payments to the Purchaser of all amounts due thereon by wire
transfer by 1:00 p.m. on the date of payment to such account as is specified
beneath the Purchaser's name on the signature page hereof or to such other
account or in such other similar manner as the Purchaser may designate to the
Company in writing.

            SECTION 10.6. Register. The Company shall keep at its principal
office a register (the "Register") in which shall be entered the names and
addresses of the registered holders of the Notes and particulars of the
respective Notes held by them and of all transfers of such Notes. References to
the "Holder" or "Holders" shall mean the Person or Persons listed in the
Register as the payee of any Note. The ownership of the Notes shall be proven by
the Register.

            SECTION 10.7. Successors and Assigns. This Agreement shall be
binding upon the Company and upon the Purchaser and their respective successors
and assigns; provided, however, that the Company shall not assign or otherwise
transfer its rights or obligations under this Agreement to any other Person
without the prior written consent of the Majority Holders. All provisions
hereunder purporting to give rights to DLJ and its Affiliates or to Holders are
for the express benefit of such Persons.

            SECTION 10.8. New York Law; Submission to Jurisdiction; Waiver of
Jury Trial. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE
PERFORMED IN THAT STATE. EACH PARTY HERETO HEREBY SUBMITS TO THE EXCLUSIVE
JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE 
<PAGE>   52

                                      -47-


SOUTHERN DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN NEW
YORK CITY FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH
IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING
BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A
COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

            SECTION 10.9. Independence of Representations, Warranties and
Covenants. The representations, warranties and covenants contained herein shall
be independent of each other, and no exception to any representation, warranty
or covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein unless expressly provided, nor shall any
such exception be deemed to permit any action or omission that would be in
contravention of applicable law.

            SECTION 10.10. Severability. If any provision of this Agreement, or
the application of such provision to any Person or circumstance, is held by a
court of competent jurisdiction to be invalid, the remainder of this Agreement
or the application of such provision to other Persons or circumstances shall in
no way be affected thereby; provided, however, that the parties shall negotiate
in good faith to replace the offending provision or application with a
substitute provision or application that will have substantially the same
economic effect. To the extent that it may effectively do so under applicable
law, each party hereby waives any provision of law which renders any provision
of this Agreement invalid, illegal or unenforceable in any respect.

            SECTION 10.11. Entire Agreement; Benefit. This Agreement and the
other Financing Documents constitute the entire contract among the parties
relating to the subject matter hereof. Any previous agreement among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the other Financing Documents. Nothing in any Financing Document is intended to
confer upon any Person (other than the parties thereto and any Indemnified
Party) any rights, remedies, obligations or liabilities under or by reason of
the Financing Documents.

            SECTION 10.12. Headings. Article and Section headings and the Tables
of Contents and Exhibits and Schedules are for convenience of reference only,
are not part of this Agreement and are not to affect the construction of, or to
be taken into consideration in interpreting, this Agreement.

            SECTION 10.13. Counterparts. This Agreement may be executed in any
number of counterparts each of which shall be an original with the same effect
as if the signatures thereto and hereto were upon the same instrument.

            SECTION 10.14 Confidentiality. The Purchaser agrees to take normal
and reasonable precautions to maintain the confidentiality of information
provided to it by the Company in connection with this Agreement to the extent it
is not a matter of general public knowledge or it was not previously known to
the Purchaser at the time such information was provided to it; provided,
however, that the Purchaser may disclose such information (a) at the request of
any bank regulatory or securities authority or the National Association of
Insurance Commissioner (the "NAIC") or in connection with an examination of the
Purchaser by any such authority or the NAIC, (b) pursuant to subpoena or other
court process, (c) when required to do so in accordance with the provisions of
any applicable law, (d) at the direction of any governmental authority, (e) to
the Purchaser's Affiliates, independent auditors and other professional advisors
or (f) to any transferee or potential transferee or to any direct or indirect
contractual counterparties in swap agreements or to the professional advisors of
such swap counterparties; provided, however, that in the case of (e) or (f) they
agree with the Company to comply with the provisions of this Section 10.14.

                       Senior Secured Increasing Rate Note

OXFORD HEALTH PLANS, INC., a Delaware corporation (together with its successors,
the "Company"), for value received hereby promises to pay to

                                [NAME OF HOLDER]

(the "Holder") and registered assigns the principal sum of

                [Amount in words] Dollars ($[Amount in numbers])

by wire transfer of immediately available funds to the Holder's account (the
"Bank Account") at such bank in the United States as may be specified in writing
by the Holder to the Company, on the earlier of (i) the date which is one year
after the Closing Date (as defined in the Bridge Securities Purchase Agreement
referred to below) and (ii) the date the principal amount of the Notes shall be
declared to be or shall automatically become (as provided in Article 8 of the
Bridge Securities Purchase Agreement) due and payable (in any such case, the
"Maturity Date") in such coin or currency of the United States of America as at
the time of payment shall be legal tender for the payment of public and private
debts, and to pay interest, quarterly in arrears, on the [date corresponding to
Closing Date] day of each third month after the Closing Date (unless such day is
not a Business Day, in which event on the next succeeding Business Day) (each an
"Interest Payment Date") and on the Maturity 
<PAGE>   56

Date, on the principal sum hereof outstanding in like coin or currency, at the
rates per annum set forth below, by wire transfer of immediately available funds
to the Bank Account from the most recent Interest Payment Date to which interest
has been paid on this Note, or if no interest has been paid on this Note, from
the date of this Note until payment in full of the principal sum hereof has been
made.

            This Note is one of a duly authorized issue of Notes of the Company
(the "Notes") referred to in the Bridge Securities Purchase Agreement dated as
of February 6, 1998 between the Company and Oxford Funding, Inc. (the
"Purchaser") (as the same may be amended from time to time in accordance with
its terms, the "Agreement"). All terms defined in the Agreement and not
otherwise defined herein shall have for purposes hereof the meanings provided
for therein.

        This Note shall bear interest at a rate per annum (the "Interest Rate")
equal to the sum of (i) the Prime Rate in effect from time to time plus (ii) 
250 basis points plus (iii) an additional spread equal to 0 basis points  prior
to the date which is three months after the Closing Date and 50 basis points
from and including the date which is three months after the Closing Date,
increasing by 50 basis points at the end of each subsequent three-month period,
until the principal amount hereof is paid in full or, in any case, if less, the
maximum rate permitted by applicable law. "Prime Rate" means, for any day, a
rate per annum equal to the rate of interest publicly announced by The Bank of
New York (or its successor) from time to time in The City of New York as its
prime, reference or base rate. The Interest Rate shall be reduced by 50 basis
points on the date on which the Purchaser purchases Notes in excess of the
Initial Commitment Amount.

        Notwithstanding anything to the contrary set forth herein, at no time
shall the per annum interest rate on this Note exceed seventeen * percent (17  
%), nor shall the per annum interest rate on this Note be lower than * ten and
one-half percent  (10.50 * %). In addition, that portion, if any, of any
interest payment representing  a per annum interest rate in excess of fifteen *
percent (15.0 * %) may be paid, at the option of the Company, by issuing and
delivering Notes with a principal amount equal to such excess portion of
interest.

            Interest on this Note will be calculated on the basis of a 365-day
year and paid for the actual number of days elapsed.

            This Note is transferable and assignable to one or more purchasers
in accordance with the provisions set forth in the Agreement. The Company agrees
to issue from time to time replacement Notes in the form hereof to facilitate
such transfers and assignments.

            Unless the Majority Holders otherwise consent in writing, the
Company covenants and agrees to observe and perform each of its obligations and
undertakings contained in Article VI of the Agreement, which obligations and
undertakings are expressly assumed herein by the Company and made for the

time to time in accordance with the provisions of the Agreement.

on this Note may be declared to be or become automatically due and payable in
the manner and with the effect provided in the Agreement.

            This Note shall be deemed to be a contract made under the laws of
the State of New York, and for all purposes shall be governed by and construed
in accordance with the laws of said State applicable to contracts made and to be
performed in that State. The parties hereto, including all guarantors or
endorsers, hereby waive presentment, demand, notice, protest and all other
demands and notices in connection with the delivery, acceptance, performance and
enforcement of this Note, except as specifically provided herein, and assent to
extensions of the time of payment, or forbearance or other indulgence without
notice. The Company hereby submits to the exclusive jurisdiction of the United
States District Court for the Southern District of New York and of any New York
state court sitting in New York City for purposes of all legal proceedings
arising out of or relating to this Note. The Company irrevocably waives, to the
fullest extent permitted by law, any objection which it may now or hereafter
have to the laying of the venue of any such proceeding brought in such a court
and any claim that any such proceeding brought in such a court has been brought
in an inconvenient forum. The Company hereby irrevocably waives any and all
right to trial by jury in any legal proceeding arising out of or relating to
this Note.
