	"Collateral."  The Collateral shall consist of the 1,301,422 shares of Lender's common stock, par value $.001 per
share (the "Pledge Shares") plus any stock dividend, stock split, distribution of capital or other distribution or payment declared upon the Pledge Shares.

	3.
	"Fair Market Value."  Fair market value means the average closing price of Lender's common stock as reported on NASDAQ

obligations under the Note;

	the
repayment of (a) any amounts that Lender may advance or spend for the maintenance or preservation of the Collateral, and (b) any other expenditures that Lender

	(iii)
	all
amounts owed under any modifications, renewals or extensions of any of the foregoing obligations; and

	(iv)
	any
of the foregoing that arises after the filing of a petition by or against Borrower under the Bankruptcy Code, even if the obligations do not accrue because of the automatic
stay under Bankruptcy Code §362 or otherwise.

	2.
	The Note.  The loan will be evidenced by a Secured Promissory Note in the form attached hereto as  Exhibit A.
Borrower agrees to execute the Note in the amount advanced from time to time by the Lender. The Note shall be a
non-recourse Note, and Borrower shall have no liability for any amounts under the Note except to the extent of the Collateral.

	3.
	Interest.  The amount advanced by Lender under this Agreement shall bear interest on the unpaid principal balance at

part, with accrued interest to the date of such prepayment on the amount prepaid. Any partial prepayments of the loan will be applied first to accrued interest and then to principal.

	5.

Treasury Stock to satisfy the Obligations, Lender will credit all of the Obligations of Borrower and return the balance of the Pledge Shares to Borrower.

Ladies and Gentlemen:

            Digex, Incorporated, a Delaware corporation (the "COMPANY"), agrees
with you as follows (the "AGREEMENT"):

                                    ARTICLE I

                            AUTHORIZATION OF NOTES

            The Company will authorize the issue and sale of Senior Notes (the
"NOTES", such term to include any such notes issued in substitution therefor
pursuant to Article XIII of this Agreement) up to an aggregate principal amount
equal to the Total Purchase Amount. The Notes shall be substantially in the form
set out in EXHIBIT I, with such changes therefrom, if any, as may be approved by
you and the Company. Certain capitalized terms used in this Agreement are
defined in SCHEDULE A; references to a "Schedule" or an "Exhibit" are, unless
otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

<Page>
                                                                               2

                                   ARTICLE II

                           SALE AND PURCHASE OF NOTES

            SECTION 2.01. SALE AND PURCHASE OF NOTES . Subject to the terms and
conditions of this Agreement, the Company will issue and sell to you and you
will purchase from the Company, on each Purchase Date, Notes at the purchase
price of 100% of the principal amount of such Purchase (the "PURCHASE PRICE");
PROVIDED that, without your prior written consent, (a) the aggregate principal
amount of all Purchases in any one-month period during 2001 shall not exceed 20%
of the total amount of funding of the Company by you, as approved in the 2001
Business Plan, (b) the aggregate principal amount of all Purchases in any Fiscal
Quarter during 2001 shall not exceed 60% of the total amount of funding of the
Company by you, as approved in the 2001 Business Plan, (c) the aggregate
principal amount of all Purchases in any one-month period during 2002 shall not
exceed 12.5% of the total amount of funding of the Company by you, as approved
in the 2002 Business Plan, and (d) the aggregate principal amount of all
Purchases in any Fiscal Quarter during 2002 shall not exceed 30% of the total
amount of funding of the Company by you, as approved in the 2002 Business Plan.
It is understood that, in connection with the 2002 Business Plan approval
process described in Section 9.07, the parties will mutually discuss whether to
amend the percentages in clauses (c) and (d) of the preceding sentence. The
aggregate principal amount of all Purchases shall not exceed the Total Purchase
Amount.

            SECTION 2.02. PROCEDURE FOR PURCHASING . In order to effect a
Purchase hereunder, the Company shall give you irrevocable notice (which notice
must be received by you prior to 12:00 noon, New York City time, five Business
Days prior to the Purchase Date, PROVIDED, however, that, with respect to the
Initial Purchase (as defined below), the Company may provide notice to you one
Business Day prior to the Closing Date with respect to such Initial Purchase),
specifying the amount of Notes to be purchased and the Purchase Date (a
"Borrowing Notice"). The Borrowing Notice shall be substantially in the form set
out in EXHIBIT II, with such changes in form therefrom, if any, as may be
approved by you and the Company. Each Purchase shall be in an aggregate amount
equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if
the then aggregate Available Purchase Amount is less than $5,000,000, such
lesser amount). You will make the Purchase Price available to the Company by
3:00 p.m., New York City time, on the Purchase Date in funds immediately
available to the Company. If the Borrowing Notice is received after 12:00 noon
as set forth above in this Section, such Borrowing Notice shall be deemed to
have been received on the following Business Day. No Borrowing Notice need be
accepted by you after December 6, 2002.

            SECTION 2.03. INTEREST . Subject to the provisions of Section 2.04,
each Note shall bear interest for each day at a rate per annum equal to the
Interest Rate. Interest on the unpaid balance of the aggregate principal amount
of all Notes will be due and payable on the first day of each calendar month.
Interest also shall be paid on the Maturity Date and upon any prepayment of
principal with respect to the principal repaid. Interest and fees payable
pursuant hereto shall be calculated on the basis of a year of 365 days (or 366
days in a leap year) for the actual days elapsed.

                                                                               3

            SECTION 2.04. ALTERNATE RATE OF INTEREST . If on any Date of
Determination you determine (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining
LIBOR, then you shall give notice thereof to the Company by telephone or
telecopy as promptly as practicable thereafter, and, until you notify the
Company that the circumstances giving rise to such notice no longer exist, the
interest rate that otherwise would have been determined on such Date of
Determination shall be the Alternate Interest Rate.

            SECTION 2.05. INCREASED COSTS. (a) If any Change in Law shall:

            (i) impose, modify or deem applicable any reserve, special deposit
      or similar requirement against assets of, deposits with or for the account
      of, or credit extended by, any holder of a Note or

            (ii) impose on any holder of a Note or the London interbank market
      any other condition affecting this Agreement,

and the result of any of the foregoing shall be to increase the cost to such
holder of holding any Note (or of maintaining its obligation to hold any such
Note) or to reduce the amount of any sum received or receivable by such holder
hereunder (whether of principal, interest or otherwise), then the Company will
pay to such holder such additional amount or amounts as will compensate such
Holder for such additional costs actually incurred or reduction actually
suffered.

            (b) If any holder of any Note determines that any Change in Law
regarding capital requirements has or would have the effect of reducing the rate
of return on such holder's capital or on the capital of such holder's holding
company, if any, as a consequence of this Agreement or the Purchases made by
such holder, to a level below that which such holder or such holder's holding
company could have achieved but for such Change in Law (taking into
consideration such holder's policies and the policies of such holder's holding
company with respect to capital adequacy), then from time to time the Company
will pay to such holder such additional amount or amounts as will compensate
such holder or such holder's holding company for any such reduction actually
suffered.

            (c) A certificate of any holder of any Note setting forth the amount
or amounts necessary to compensate such holder or its holding company, as the
case may be, as specified in paragraph (a) or (b) of this Section shall be
delivered to the Company and shall be conclusive absent manifest error. The
Company shall pay such holder the amount shown as due on any such certificate
within 10 days after receipt thereof.

            (d) A holder of a Note who becomes entitled to compensation under
this Section 2.05 shall give prompt written notice after such holder becomes
aware of such entitlement, but failure or delay on the part of any holder of any
Note to demand compensation pursuant to this Section shall not constitute a
waiver of such holder's right to demand such compensation.

<Page>
                                                                               4

            Notwithstanding any other provision of this Section 2.05, no holder
of a Note shall demand compensation for any increased costs or reduction
referred to above if it shall not be the general policy or practice of such
holder to demand such compensation in similar circumstances under comparable
provisions of other note purchase, credit or loan agreements, if any (it being
understood that this sentence shall not in any way limit the discretion of any
holder to waive the right to demand such compensation in any given case).

            SECTION 2.06. BREAK-FUNDING PAYMENTS . In the event of the payment
of any principal of any Purchase other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default) or the
failure to purchase, prepay or repurchase any Note on the date specified in any
notice delivered pursuant hereto (regardless of whether such notice is revoked),
then, in any such event, the Company shall compensate each holder of any such
Note for the loss, cost and expense attributable to such event. In the case of a
Purchase, the loss to any holder of a Note attributable to any such event shall
be deemed to include an amount determined by such holder to be equal to the
excess, if any, of (a) the amount of interest that such holder would pay for a
deposit equal to the principal amount of such Note for the period from the date
of such payment or failure to the last day of the then current Interest Period
for such Note (or, in the case of a failure to purchase or repurchase, the
duration of the Interest Period that would have resulted from such purchase or
repurchase) if the interest rate payable on such deposit were equal to the
Interest Rate for such Interest Period over (b) the amount of interest that such
holder would earn on such principal amount for such period if such holder were
to invest such principal amount for such period at the interest rate that would
be bid by such holder (or an affiliate of such holder) for dollar deposits from
banks in the market of loans bearing interest at a rate determined by reference,
in whole or in part, directly or indirectly, to LIBOR at the commencement of
such period. A certificate of any holder setting forth any amount or amounts
that such holder is entitled to receive pursuant to this Section shall be
delivered to the Company and shall be conclusive absent manifest error. The
Company shall pay such holder the amount shown as due on any such certificate
within 10 days after receipt thereof.

            SECTION 2.07. MATURITY . Except as provided in Section 2.08, the
Notes shall mature (the "MATURITY DATE"), and shall be immediately due and
payable without any requirement of demand or request by you, on December 31,
2002.

            SECTION 2.08. TERM-OUT OPTION . Upon the election of the Company by
written notice (the "TERM-OUT NOTICE") given not later than December 13, 2002,
to all holders of Notes, the Company may elect (the "TERM-OUT ELECTION") to
extend the maturity of all the then outstanding Notes to December 31, 2006. If
the Company so elects, the Notes shall thereafter have required equal monthly
straight-line amortization payments prior to final maturity. From and after the
date of delivery of the Term-Out Notice, the references to Maturity Date herein
shall be deemed to be appropriately modified to reflect such election.

                                   ARTICLE III

                                    PURCHASE

            On the date of each Purchase, the Company will deliver to you the
Notes to be purchased by you in the form of a single Note (or such greater
number of Notes in denominations of at least $100,000 as you may request), dated
the Purchase Date and registered in your name (or in the name of your nominee),
as you shall request, against delivery by you to the Company or its order of
immediately available funds in the amount of the Purchase Price therefor by wire
transfer of immediately available funds for the account of the Company to:

fulfilled to your satisfaction, you shall, at your election, be relieved of all
further obligations under this Agreement with respect to such Purchase, without
thereby waiving any rights you may have by reason of such failure or such
nonfulfillment.

            (ii) the Company shall have provided you with a schedule setting
      forth the actual uses and expenditures from the previous Purchase and the
      proposed uses and expenditures of the proceeds of the Purchase (a

              liability under or pursuant to any applicable law or regulation,
              which law or regulation was not in effect on the date hereof. If
              requested by you, you shall have received an Officer's Certificate
              certifying as to such matters of fact as you may reasonably
              specify to enable you to determine whether such purchase is so
              permitted.

              (e) OFFICERS' CERTIFICATE. The Company shall have delivered to you
              an Officer's Certificate, dated as of the Purchase Date,

            (i) that each of the conditions specified in Sections 4.02(a)-(d)
      above has been fulfilled,

            (ii) as to whether such Purchase violates, or is expected after duly

            amount, or

                  (B) as to which provision or provisions of the Intermedia Debt
            Documents provide satisfaction of any other provisions therein that
            would otherwise restrict such Purchase, and, in each case, as to
            what amount;

      PROVIDED, HOWEVER, that any such purported violation or restriction in the
      Intermedia Debt Documents shall not relieve you of your obligation under
      this Agreement to purchase, or cause to be purchased, Notes requested to
      be purchased on any Purchase Date.

                                    ARTICLE V

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            The Company represents and warrants to you that:

            SECTION 5.01. ORGANIZATION; POWER AND AUTHORITY . The Company and
each of its Subsidiaries are duly organized, validly existing and in good
standing under the laws of their jurisdiction of incorporation or organization,
as applicable (such jurisdictions being identified on SCHEDULE 5.01, as
supplemented and modified in writing from time to time to reflect any changes to
such Schedule as a result of transactions permitted by this Agreement); are duly
qualified as foreign corporations or foreign entities, as applicable; and are in
good standing in each jurisdiction in which such qualification is required by
law, other than those jurisdictions as to which the failure to be so qualified
or in good standing could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Company and each of its
Subsidiaries possess all Authorizations, licenses and grants necessary or
required in the conduct of their respective businesses, except where the failure
to have such Authorizations, licenses or grants would not reasonably be expected
to result in a Material Adverse Effect; and the same which are described on
SCHEDULE 5.01 hereto are valid, binding, enforceable, and subsisting without any
material defaults thereunder or enforceable adverse limitations thereon and are
not subject to any proceedings or claims opposing the issuance, development, or
use thereof or contesting the validity thereof. No Authorization, development,
or formal exemptions from, nor any filing, declaration, or registration with,
any Governmental Authority (federal, state, or local), or non-governmental
entity, under the terms of contracts or otherwise, is required by reason of or
in connection with the execution and performance of this Agreement or the Notes
by the Company, except where the failure to have such Authorizations, licenses
or grants would not reasonably be expected to result in a Material Adverse
Effect. The Company has the corporate power and authority to own or hold under
lease the properties it purports to own or hold under lease, to transact the
business it transacts and proposes to transact, to execute and deliver this
Agreement and the Notes and to perform the provisions hereof.

            SECTION 5.02. AUTHORIZATION, ETC. (a) This Agreement and the Notes
have been duly authorized by all necessary corporate action on the part of the
Company, and this Agreement constitutes, and upon execution and delivery thereof
each Note will constitute, a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and (ii) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

            (b) Each of the 2001 Business Plan and the 2002 Business Plan (when
applicable), as most recently approved by your Board of Directors, has been
neither amended, revised, rescinded nor modified by the Company's Board of
Directors (unless the Company has notified you to that effect pursuant to
Section 9.07), and such Approved Business Plans (as so amended, revised or
modified) accurately represent the Company's

<Page>
                                                                              10

best estimate as of the date thereof of the funding it needs for its operations
for the periods (1) from July 1, 2001 through December 31, 2001, and (2) from
January 1, 2002, through December 31, 2002, respectively.

            SECTION 5.03. DISCLOSURE. Except as disclosed in SCHEDULE 5.03, this
Agreement, the documents, certificates or other writings delivered to you by or
on behalf of the Company in connection with the transactions contemplated hereby
and the financial statements listed in SCHEDULE 5.05, taken as a whole, do not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Except as disclosed in SCHEDULE 5.03,
or in one of the documents, certificates or other writings identified therein,
or in the financial statements listed in SCHEDULE 5.05, since December 31, 2000,
there has been no change in the financial condition, operations, business,
properties or prospects of the Company or any of its Subsidiaries except changes
that individually or in the aggregate could not reasonably be expected to have a
Material Adverse Effect. There is no fact known to the Company that could
reasonably be expected to have a Material Adverse Effect that has not been set
forth herein or in the other documents, certificates and other writings
delivered to you by or on behalf of the Company specifically for use in
connection with the transactions contemplated hereby.

            SECTION 5.04. ORGANIZATION AND OWNERSHIP OF SHARES OF SUBSIDIARIES;
AFFILIATES. (a) SCHEDULE 5.04 contains (except as noted therein) complete and
correct lists, as of the date hereof, of (i) the Company's Subsidiaries,

its organization, and the percentage of shares of each class of its capital
stock or similar equity interests outstanding owned by the Company and each
other Subsidiary, (ii) the Company's Affiliates, other than Subsidiaries, and
(iii) the Company's directors and senior officers.

            (b) All of the outstanding shares of capital stock or similar equity
interests of each Subsidiary shown in SCHEDULE 5.04 as being owned by the
Company and its Subsidiaries have been validly issued, are fully paid and
nonassessable and, as of the date hereof, are owned by the Company or another
Subsidiary free and clear of any Lien (except as otherwise disclosed in SCHEDULE
5.04).

            (c) Each Subsidiary identified in SCHEDULE 5.04 is a corporation or
other legal entity duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization, and is duly qualified as a foreign
corporation or other legal entity and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has the corporate or other power and
authority to own or hold under lease the properties it purports to own or hold
under lease and to transact the business it transacts and proposes to transact.

                                                                              11

            (d) No Subsidiary of the Company is a party to, or otherwise subject
to, any legal restriction or any agreement (other than this Agreement, the
agreements listed on SCHEDULE 5.04 and customary limitations imposed by
corporate law statutes) restricting the ability of such Subsidiary to pay
dividends out of profits or make any other similar distributions of profits to
the Company or any of its Subsidiaries that owns outstanding shares of capital
stock or similar equity interests of such Subsidiary.

            SECTION 5.05. FINANCIAL STATEMENTS. The Company has delivered to you
copies of the financial statements of the Company and its Subsidiaries listed on
SCHEDULE 5.05. All of such financial statements (including in each case the
related schedules and notes) fairly present in all material respects the
consolidated financial position of the Company and its Subsidiaries as of the
respective dates specified in such Schedule and the consolidated results of
their operations and cash flows for the respective periods so specified and have
been prepared in accordance with GAAP consistently applied throughout the
periods involved except as set forth in the notes thereto (subject, in the case
of any interim financial statements, to normal year-end adjustments).

            SECTION 5.06. COMPLIANCE WITH LAWS, OTHER INSTRUMENTS, ETC. The
execution, delivery and performance by the Company of this Agreement and the
Notes will not (a) contravene, result in any breach of, or constitute a default
under, or result in the creation of any Lien in respect of any property of the
Company or any of its Subsidiaries under, any indenture, mortgage, deed of
trust, loan, purchase or credit agreement, lease, corporate charter or by-laws,
or any other agreement or instrument to which the Company or any of its
Subsidiaries is bound or by which the Company or any of its Subsidiaries or any
of their respective properties may be bound or affected, (b) conflict with or
result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree, or ruling of any, court, arbitrator or Governmental Authority
applicable to the Company or any of its Subsidiaries or (c) violate any
provision of any statute or other rule or regulation of any Governmental
Authority applicable to the Company or any of its Subsidiaries, in each case,
except for such contraventions, breaches, defaults, conflicts and violations
that could not have a Material Adverse Effect.

            SECTION 5.07. LITIGATION; OBSERVANCE OF AGREEMENTS, STATUTES AND
ORDERS. (a) Except as disclosed in SCHEDULE 5.07, there are no actions, suits or
proceedings pending or, to the knowledge of the Company, threatened against or
affecting the Company or any of its Subsidiaries or any property of the Company
or any of its Subsidiaries in any court or before any arbitrator of any kind or
before or by any Governmental Authority that, individually or in the aggregate,
could reasonably be expected to have a Material Adverse Effect.

            (b) Neither the Company nor any of its Subsidiaries is in default
under any term of any agreement or instrument to which it is a party or by which
it is bound, or any order, judgment, decree or ruling of any court, arbitrator
or Governmental Authority or is in violation of any applicable law, ordinance,
rule or regulation (including Environmental Laws) of any Governmental Authority,
which default or violation, individually or in the aggregate, could reasonably
be expected to have a Material Adverse Effect.

                                                                              12

            SECTION 5.08. TAXES. All Tax returns of the Company and each of its
Subsidiaries required to be filed have been filed (or extensions have been
granted) prior to delinquency, except for any such returns for which the failure
to so file could not have a Material Adverse Effect, and all Taxes imposed upon
the Company and each of its Subsidiaries that are due and payable have been paid
prior to delinquency, OTHER THAN Taxes for which the criteria for Permitted
Liens have been satisfied or for which nonpayment thereof could not reasonably
be expected to have a Material Adverse Effect.

            SECTION 5.09. TITLE TO PROPERTY; LEASES. The Company and its
Subsidiaries have good and sufficient title to their respective properties that
individually or in the aggregate are Material, including all such properties
reflected in the most recent audited balance sheet referred to in Section 5.05

after said date (except as sold or otherwise disposed of in the ordinary course
of business), in each case free and clear of Liens prohibited by this Agreement.
All leases that individually or in the aggregate are Material are valid and
subsisting and are in full force and effect in all material respects.

            SECTION 5.10. LICENSES, PERMITS, ETC. Except as disclosed in
SCHEDULE 5.10,

            (a) the Company and its Subsidiaries own or possess all licenses,
      permits, franchises, authorizations, patents, copyrights, service marks,
      trademarks and trade names, or rights thereto, that individually or in the
      aggregate are Material, without known conflict with the rights of others;

             (b) to the best knowledge of the Company, no product of the Company
      infringes in any material respect any license, permit, franchise,
      authorization, patent, copyright, service mark, trademark, trade name or
      other right owned by any other Person; and

             (c) to the best knowledge of the Company, there is no Material
      violation by any Person of any right of the Company or any of its

                                                                              13

            SECTION 5.11. COMPLIANCE WITH ERISA. (a) No Employee Plan has
incurred an "accumulated funding deficiency" (as defined in Section 302 of ERISA
and Section 412 of the Code), (b) neither the Company nor any of its
Subsidiaries or any ERISA Affiliate has incurred material liability to the PBGC
or with respect to an Employee Plan, which liability is currently due and
remains unpaid under Title IV of ERISA, (c) each Employee Plan subject to ERISA
and the Code complies in all material respects, both in form and operation, with
ERISA and the Code, (d) no ERISA Event has occurred or is reasonably expected to
occur with respect to any Employee Plan or Multiemployer Plan that, individually
or collectively with all other ERISA Events then existing, could reasonably be
expected to have a Material Adverse Effect, (e) the present value of all accrued
benefits under each Employee Plan (based on actuarial assumptions used for
funding purposes in the most recent actuarial valuation prepared by the Employee
Plan's actuary with respect to such Employee Plan) did not, as of the last
annual actuarial valuation date for such Employee Plan, exceed the then-current
value of the assets of such Employee Plan, and (f) the present value of accrued
benefits under each Employee Plan (based on PBGC actuarial assumptions used for
plan termination), on any date of determination, does not exceed the value of
the assets of such Employee Plan.

            SECTION 5.12. PRIVATE OFFERING BY THE COMPANY. Neither the Company
nor anyone acting on its behalf has offered the Notes or any similar securities
for sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, any person other than you.
Neither the Company nor anyone acting on its behalf has taken, or will take, any
action that would subject the issuance or sale of the Notes to the registration
requirements of Section 5 of the Securities Act.

            SECTION 5.13. USE OF PROCEEDS; MARGIN REGULATIONS. No part of the
proceeds from the sale of the Notes hereunder will be used, directly or
indirectly, for the purpose of buying or carrying any margin stock within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System,
or for the purpose of buying or carrying or trading in any securities under such
circumstances as to involve the Company in a violation of Regulation X of said
Board or to involve any broker or dealer in a violation of Regulation T of said
Board. Margin stock does not constitute more than 5 % of the value of the
consolidated assets of the Company and its Subsidiaries, and the Company does
not have any present intention that margin stock will constitute more than 5 %
of the value of such assets. As used in this Section, the terms "margin stock"
and "purpose of buying or carrying" shall have the meanings assigned to them in
said Regulation U. All proceeds from the sale of the Notes by the Company will
be used by the Company to fund its operations and capital-expenditure
requirements in a manner consistent with the Approved Business Plans, and such
proceeds may also be used to fund interest payments on the Notes as well as to
refinance any outstanding intercompany borrowings from Intermedia.

            SECTION 5.14. EXISTING INDEBTEDNESS; FUTURE LIENS. (a) Except as
described therein, SCHEDULE 5.14 sets forth a complete and correct list of all
outstanding Indebtedness of the Company and its Subsidiaries as of the Closing
Date, since which there has been no Material change in the amounts, interest
rates, sinking funds, installment payments or maturities of the Indebtedness of
the Company or its Subsidiaries, except

<Page>
                                                                              14

pursuant to incurrences of Indebtedness permitted by Section 10.03 and payments
of Indebtedness made in accordance with the terms of the applicable agreements
evidencing such Indebtedness. Neither the Company nor any of its Subsidiaries is
in default and no waiver of default is currently in effect, in the payment of
any principal or interest on any Indebtedness of the Company or such Subsidiary,
and no event or condition exists with respect to any Indebtedness of the Company
or any Subsidiary that would permit (or that with notice or the lapse of time,
or both, would permit) one or more Persons to cause such Indebtedness to become
due and payable before its stated maturity or before its regularly scheduled
dates of payment.

            (b) Except as disclosed in SCHEDULE 5.14, neither the Company nor
any of its Subsidiaries has agreed or consented to cause or permit in the future
(upon the happening of a contingency or otherwise) any of its property, whether
now owned or hereafter acquired, to be subject to a Lien not permitted by
Section 10.06.

            SECTION 5.15. STATUS UNDER CERTAIN STATUTES. Neither the Company nor
any of its Subsidiaries is subject to regulation under the Investment Company
Act of 1940, as amended, the Public Utility Holding Company Act of 1935, as
amended, or any other law (other than Regulations T, U, and X of the Board of
Governors of the Federal Reserve System and the requirements of any PUC or
public service commission) that regulates the incurrence of Indebtedness.

            SECTION 5.16. ENVIRONMENTAL MATTERS. Neither the Company nor any of
its Subsidiaries (a) knows of any environmental condition or circumstance, such
as the presence or Release of any Hazardous Material, on any property presently
or previously owned by the Company or any of its Subsidiaries that could
reasonably be expected to have a Material Adverse Effect, (b) knows of any
violation by the Company or any of its Subsidiaries of any Environmental Law,
except for such violations that could not reasonably be expected to have a
Material Adverse Effect, or (c) knows that the Company or any of its
Subsidiaries is under any obligation to remedy any violation of any
Environmental Law, except for such obligations that could not reasonably be
expected to have a Material Adverse Effect; PROVIDED that the Company and each
of its Subsidiaries (x) to the best of its knowledge, has in full force and
effect all environmental permits, licenses, and approvals required to conduct
its operations and is operating in substantial compliance thereunder, and (y)
has taken prudent steps to determine that its properties and operations are not
in violation of any Environmental Law.

            SECTION 5.17. INSURANCE. The Company and each of its Subsidiaries
maintains, with financially sound, responsible, and reputable insurance
companies or associations, insurance concerning its properties and businesses
against such casualties and contingencies and of such types and in such amounts
(and with co-insurance and deductibles) as is customary in the case of same or
similar businesses.

            SECTION 5.18. INTELLECTUAL PROPERTY. The Company and each of its
Subsidiaries owns or has sufficient and legally enforceable rights to use all
material licenses, patents, patent applications, copyrights, service marks,
trademarks, trademark applications, and trade names necessary to continue to
conduct its businesses as heretofore conducted by it, now conducted by it, and
now proposed to be conducted by it. The Company and each of its Subsidiaries is
conducting its business without infringement or claim of infringement of any
license, patent, copyright, service mark, trademark, trade name, trade secret,
or other intellectual property right of others, other than any such
infringements or claims that, if successfully asserted against or determined
adversely to the Company or any of its Subsidiaries, could not, individually or
collectively, reasonably be expected to constitute a Material Adverse Event.

                         REPRESENTATION OF THE PURCHASER

            You represent that you are purchasing the Notes for your own account
or for one or more separate accounts maintained by you or for the account of one
or more pension or trust funds and not with a view to the distribution thereof;
PROVIDED that the disposition of your or their property shall at all times be
within your or their control. You understand that the Notes have not been
registered under the Securities Act and may be resold only if registered
pursuant to the provisions of the Securities Act or if an exemption from
registration is available, except under circumstances where neither such
registration nor such an exemption is required by law, and that the Company is
not required to register the Notes.

                             PREPAYMENT OF THE NOTES

            SECTION 8.01. OPTIONAL PREPAYMENTS. The Company may, at its option,
upon notice as provided below, prepay at any time all, or from time to time any
part of, the Notes, at 100% of the principal amount so prepaid, plus accrued and
unpaid interest. The minimum principal amount of each such prepayment shall be
equal to $2,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if
the then aggregate principal amount of Notes outstanding is less than
$3,000,000, such lesser amount) . The Company will give all holders of Notes
written notice of each optional prepayment under this Section 8.01 not less than
5 Business Days and not more than 10 Business Days prior to the date fixed for
such prepayment. Each such notice shall specify such date, the aggregate
principal amount of the Notes to be prepaid on such date, the principal amount
of each Note to be prepaid, the interest to be paid on the prepayment date with
respect to such principal amount being prepaid and whether such optional
prepayment is a permanent prepayment. Any amounts prepaid that are not so
specified to be permanent prepayments may be repurchased in accordance with the
procedures for purchasing set forth in Section 2.02. If any prepayment is made
on a date other than the last day of an Interest Period so that a payment is due
pursuant to Section 2.06 hereto, or if any other amount is due pursuant to this
Agreement, you will notify the Company and the Company will pay you such amount
on such date.

            SECTION 8.02. MANDATORY PREPAYMENTS. The Company shall, on the date
of receipt of any Net Proceeds by the Company or any of its Subsidiaries from
the sale, lease, transfer or other disposition of any assets ("ASSET Sale") of
the Company or any of its Subsidiaries, prepay any amounts outstanding under
this Agreement or the Notes in an amount equal to the amount of such Net
Proceeds. Notwithstanding the foregoing sentence, the Company shall not be
required to make any prepayments pursuant to this Section 8.02 if the Company or
any of its Subsidiaries shall apply any of the Net Proceeds it received from
such Asset Sale for reinvestment in its business within 180 days after receipt
thereof by the Company or any of its Subsidiaries, PROVIDED that the Company
shall have notified you of its intent to so reinvest such Net Proceeds.

            SECTION 8.03. MATURITY; SURRENDER, ETC. In the case of each
prepayment of Notes pursuant to this Article VIII, the principal amount of each
Note to be prepaid shall mature and become due and payable on the date fixed for
such prepayment, together with interest on such principal amount accrued to such
date, payments due in accordance with Section 2.06 hereto and any other costs of
which the Company has been notified. From and after such date, unless the
Company shall fail to pay such principal amount when so due and payable, as
aforesaid, interest on such principal amount shall cease to accrue. Any Note
paid or prepaid in full shall be surrendered to the Company and cancelled and
shall not be reissued, and no Note shall be issued in lieu of any prepaid
principal amount of any Note.

            SECTION 8.04. PURCHASE OF NOTES. The Company will not, and will not
permit any Affiliate other than you or Intermedia to, purchase, redeem, prepay
or otherwise acquire, directly or indirectly, any of the outstanding Notes
except upon the payment or prepayment of the Notes in accordance with the terms
of this Agreement and the Notes. The Company will promptly cancel all Notes
acquired by it or any Affiliate other than you or Intermedia pursuant to any
payment, prepayment or purchase of Notes pursuant to any provision of this
Agreement, and no Notes may be issued in substitution or exchange for any such
Notes.

            The Company covenants that so long as any of the Notes are
outstanding:

            SECTION 9.01. USE OF FREE CASH, ASSETS AND PROCEEDS. The Company
will, to the extent it can with commercial reasonableness do so, use (a) its
free cash (i.e., from sources other than the Notes) and assets to pay for any of

any Purchase in such a manner as to qualify such proceeds as Vendor
Indebtedness.

            SECTION 9.02. COMPLIANCE WITH LAW. The Company will and will cause
each of its Subsidiaries to comply with all laws, ordinances or governmental
rules or regulations to which each of them is subject, including Environmental
Laws, and will obtain and maintain in effect all licenses, certificates,
permits, franchises and other governmental authorizations necessary to the
ownership of their respective properties or to the conduct of their respective
businesses, in each case to the extent necessary to ensure that non-compliance
with such laws, ordinances or governmental rules or regulations or failures to
obtain or maintain in effect such licenses, certificates, permits, franchises
and other governmental authorizations could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

            SECTION 9.03. INSURANCE. The Company will and will cause each of its
Subsidiaries to maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such
amounts (including deductibles, co-insurance and self-insurance, if adequate
reserves are maintained with respect thereto) as is customary in the case of
entities of established reputations engaged in the same or a similar business
and similarly situated.

            SECTION 9.04. MAINTENANCE OF PROPERTIES. The Company will and will
cause each of its Subsidiaries to maintain and keep, or cause to be maintained
and kept, their respective properties in good repair, working order and
condition (other than ordinary wear and tear), so that the business carried on
in connection therewith may be properly conducted at all times; PROVIDED that
this Section shall not prevent the Company or any Subsidiary from discontinuing
the operation and the maintenance of any of its properties if such
discontinuance is desirable in the conduct of its business and the Company has
concluded that such discontinuance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

            SECTION 9.05. PAYMENT OF TAXES AND CLAIMS. The Company will and will
cause each of its Subsidiaries to file all tax returns required to be filed in
any jurisdiction and to pay and discharge (a) all taxes shown to be due and
payable on such returns and all other Material taxes, assessments, governmental
charges, or levies imposed on them or any of their properties, assets, income or
franchises, to the extent such taxes and assessments have become due and payable
and before they have become delinquent and (b) all claims for which sums have
become due and payable that have or might become a Lien

on properties or assets of the Company or any Subsidiary; PROVIDED that neither
the Company nor any Subsidiary need pay any such tax or assessment or claims if
the amount, applicability or validity thereof is contested by the Company or
such Subsidiary on a timely basis in good faith and in appropriate proceedings,
and the Company or a Subsidiary has established adequate reserves therefor in
accordance with GAAP on the books of the Company or such Subsidiary.

            SECTION 9.06. CORPORATE EXISTENCE, ETC. The Company will at all
times preserve and keep in full force and effect its corporate existence.
Subject to Section 10.04, the Company will at all times preserve and keep in
full force and effect the corporate, partnership or other existence of each of
its Subsidiaries (unless merged into the Company or a Subsidiary) and all rights
and franchises of the Company and its Subsidiaries unless, in the good faith
judgment of the Company, the termination of or failure to preserve and keep in
full force and effect such corporate, partnership or other existence, right or
franchise could not, individually or in the aggregate, have a Material Adverse
Effect.

            SECTION 9.07. PROVISION OF BUSINESS PLANS. (a) The Company will
deliver to you, no later than December 1, 2001, a 2002 Business Plan in at least
the same level of detail as that contained in the 2001 Business Plan attached
hereto as Exhibit III. The Company shall provide such information with respect
to the updated 2002 Business Plan as you shall reasonably request. Such 2002
Business Plan shall be subject to the approval of your Board of Directors and,
once approved, shall become the 2002 Business Plan for purposes of this
Agreement.

            (b) If any Approved Business Plan has been rescinded or materially
amended, revised or updated after either Board of Directors has approved such
plan, the Company will deliver a written notice (each such notice, a
"BUSINESS-PLAN-REVISION NOTICE") to you of such change no later than one
Business Day after the Company's Board of Directors has approved such change,
and the Company will submit a new, amended, revised or updated business plan, as
the case may be, to your Board of Directors no later than five Business Days
after having delivered the Business-Plan-Revision Notice.

            SECTION 9.08. ALTERNATIVE FINANCING. The Company will use its best
efforts to obtain a Vendor Indebtedness facility in an aggregate principal

8.02 hereto.

      approved by the Board of Directors of the Company,

            (ii) transactions between or among the Company and its Subsidiaries,
      and

respect to any Sale and Leaseback Transaction; PROVIDED that the Company or any

loss thereof is not adverse in any material respect to you.

      (or the payment of which is guaranteed by the Company or any of its
      Subsidiaries), whether such Indebtedness or Guarantee now exists or is
      created after the Closing Date, which default results in the acceleration
      (which acceleration has not been rescinded) of such Indebtedness prior to

                           REMEDIES ON DEFAULT, ETC.

            SECTION 12.01. ACCELERATION. If an Event of Default with respect to
the Company described in paragraph (g) or (h) of Article XI (other than an Event
of Default described in clause (i) of paragraph (g) or described in clause (vi)
of paragraph (g) by virtue of the fact that such clause encompasses clause (i)
of paragraph (g)) has occurred, all the Notes then outstanding shall
automatically become immediately due and payable.

holders of at least 25% of the principal amount of all Notes outstanding may at
any time, by notice to the Company, declare all the Notes then outstanding to be
immediately due and payable.

            Upon any Notes becoming due and payable under this Section 12.01,
whether automatically or by declaration, such Notes will forthwith mature and

interest thereon, shall all be immediately due and payable, in each and every
case without presentment, demand, protest or further notice, all of which are
hereby waived.

                                                                              31

            SECTION 12.02. OTHER REMEDIES. If any Default or Event of Default
has occurred and is continuing, and irrespective of whether any Notes have
become or have been declared immediately due and payable under Section 12.01,
any holder of Notes may proceed to protect and enforce the rights of such holder
by an action at law, suit in equity or other appropriate proceeding, whether for
the specific performance of any agreement contained herein or in any Note, or
for an injunction against a violation of any of the terms hereof or thereof, or
in aid of the exercise of any power granted hereby or thereby or by law or
otherwise.

            SECTION 12.03. RESCISSION. At any time after any Notes have been
declared due and payable pursuant to clause (b) of Section 12.01, the holders of
at least 25% of all outstanding Notes may, by written notice to the Company,
rescind and annul any such declaration and its consequences if (a) the Company
has paid, at the Default Rate, all overdue interest on the Notes and all
principal of any Notes that are due and payable and are unpaid other than by
reason of such declaration, and all interest on such overdue principal and (to
the extent permitted by applicable law) any overdue interest in respect of the
Notes, (b) all Events of Default and Defaults, other than non-payment of amounts
that have become due solely by reason of such declaration, have been cured or
have been waived pursuant to Article XVII and (c) no judgment or decree has been
entered for the payment of any monies due pursuant hereto or to the Notes. No
rescission and annulment under this Section 12.03 will extend to or affect any
subsequent Event of Default or Default or impair any right consequent thereon.

course of dealing and no delay on the part of any holder of Notes in exercising
any right, power or remedy shall operate as a waiver thereof or otherwise
prejudice the rights, powers or remedies of any holder of Notes. No right, power
or remedy conferred upon any holder of Notes by this Agreement or by any Note
shall be exclusive of any other right, power or remedy referred to herein or
therein or now or hereafter available at law, in equity, by statute or
otherwise. Without limiting the obligations of the Company under Article XV, the
Company will pay each holder of Notes on demand such further amount as shall be
sufficient to cover all costs and expenses incurred in any enforcement or
collection under this Article XII, including reasonable attorneys' fees,
expenses and disbursements.

executed by the registered holder of such Note or his attorney duly authorized
in writing and accompanied by the address for notices of each transferee of such
Note or part thereof and an opinion of counsel reasonably acceptable to the
Company as to the exemption from registration under the Securities Act of such
transfer), the Company shall execute and deliver, at the Company's expense
(except as provided below), one or more new Notes (as requested by the holder
thereof) in exchange therefor in an aggregate principal amount equal to the
unpaid principal amount of the surrendered Note. Each such new Note shall be
payable to such Person as such holder may request and shall be substantially in
the form of EXHIBIT I. Each such new Note shall be dated and bear interest from
the date to which interest shall have been paid on the surrendered Note or dated
the date of the surrendered Note if no interest shall have been paid thereon.
The Company may require payment of a sum sufficient to cover any stamp tax or
governmental charge imposed in respect of any such transfer of Notes. Notes

destruction or mutilation of any Note (which evidence shall be, in the case of
an Institutional Investor, notice from such Institutional Investor of such
ownership and such loss, theft, destruction or mutilation), and

            (a) in the case of loss, theft or destruction, of indemnity
reasonably satisfactory to it (PROVIDED that if the holder of such Note is, or
is a nominee for, you or another holder of a Note with a minimum net worth of at
least $100,000,000, such Person's own unsecured agreement of indemnity shall be
deemed to be satisfactory), or

            (b) in the case of mutilation, upon surrender and cancellation
thereof,

the Company shall execute and deliver, in lieu thereof, a new Note, dated and
bearing interest from the date to which interest shall have been paid on such
lost, stolen, destroyed or mutilated Note or dated the date of such lost,
stolen, destroyed or mutilated Note if no interest shall have been paid thereon.
The Company may charge for its expenses in replacing a Note.

                                   ARTICLE XIV

                               PAYMENTS ON NOTES

Company will pay all sums becoming due on such Note for principal and interest
to your account with the Bank of America in accordance with the following
information:

or by such other method or at such other address as you shall have from time to
time specified to the Company in writing for such purpose, without the

With respect to each other holder of Notes, the Company shall pay all sums
becoming due on such Notes for principal and interest to the address of such
holder as set forth in the records of the Company, without the presentation or
surrender of such Note or the making of any notation thereon. Notwithstanding
the foregoing, upon written request of the Company made concurrently with or
reasonably promptly after payment or prepayment in full of any Note, the holder
of such Note shall surrender such Note for cancellation, reasonably promptly
after any such request, to the Company at its principal executive office. Prior
to any sale or other disposition of any Note held by any holder or any holder's
nominee, such holder will, at its election, either endorse thereon the amount of
principal paid thereon and the last date to which interest has been paid thereon
or surrender such Note to the Company in exchange for a new Note or Notes
pursuant to Section 13.02. The Company will afford the benefits of this Article
XIV to any Institutional Investor that is the direct or indirect transferee of
any Note purchased by you under this Agreement and that has made the same
agreement relating to such Note as you have made in this Article XIV.

            SECTION 15.01. TRANSACTION EXPENSES. Whether or not the transactions
contemplated hereby are consummated, the Company will pay all costs and expenses
(including reasonable attorneys' fees of a special counsel and, if reasonably
required, local or other counsel) incurred by you in connection with such

in respect of this Agreement or the Notes (whether or not such amendment,
consent or waiver becomes effective), including: (a) the costs and expenses
incurred in enforcing or defending (or determining whether or how to enforce or
defend) any rights under this Agreement or the Notes or in responding to any
subpoena or other legal process or informal investigative demand issued in
connection with this Agreement or the Notes, or by reason of being a holder of
any Note, and (b) the costs and expenses, including financial advisors' fees,
incurred in connection with the insolvency or bankruptcy of the Company or any

transactions contemplated hereby and by the Notes. The Company will pay, and
will hold you harmless from, all claims in respect of any fees, costs or
expenses if any, of brokers and finders (other than those retained by you).

            SECTION 15.02. SURVIVAL. The obligations of the Company under this
Article XV will survive the payment or transfer of any Note; the enforcement,
amendment or waiver of any provision of this Agreement or the Notes; and the
termination of this Agreement.

                                   ARTICLE XVI

                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                                ENTIRE AGREEMENT

            All representations and warranties contained herein shall survive
the execution and delivery of this Agreement and the Notes, the purchase or
transfer by you of any Note or portion thereof or interest therein and the
payment of any Note, and may be relied upon by any subsequent holder of a Note,
regardless of any investigation made at any time by or on behalf of you or any
other holder of a Note. All statements contained in any certificate or other
instrument delivered by or on behalf of the Company pursuant to this Agreement
shall be deemed representations and warranties of the Company under this
Agreement. Subject to the preceding sentence, this Agreement and the Notes
embody the entire agreement and understanding between you and the Company and

                                  ARTICLE XVII

                              AMENDMENT AND WAIVER

            SECTION 17.01. REQUIREMENTS. This Agreement and the Notes may be
amended, and the observance of any term hereof or of the Notes may be waived
(either retroactively or prospectively), with (and only with) the written
consent of the Company and the holders of a majority of the principal amount of
Notes outstanding. Notwithstanding the foregoing and in order to allow you to
resell Notes to Affiliates or third parties, should you desire to do so at some
time or from time to time on or after December 31, 2002, the Company agrees to
supplement and amend this Agreement, and to waive the observance of any term
hereof or of the Notes (either retroactively or prospectively), as may be
reasonably necessary to effect any such resale, as you reasonably request, in
accordance with then-prevailing market practice.

            SECTION 17.02. SOLICITATION OF HOLDERS OF NOTES. The Company will
provide each holder of Notes with sufficient information, sufficiently far in
advance of the date a decision is required, to enable such holder to make an
informed and considered decision with respect to any proposed amendment, consent
or waiver in respect of any of the provisions hereof or of the Notes. The
Company will deliver executed or true and correct copies of each amendment,
consent or waiver effected pursuant to the provisions of this Article XVII to
each holder of Notes promptly following the date on which it is executed.

            SECTION 17.03. BINDING EFFECT, ETC. Any amendment or waiver
consented to as provided in this Article XVII is binding upon each holder of
Notes and upon each future holder of any Note and upon the Company without
regard to whether such Note has been marked to indicate such amendment or
waiver. No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or waived
or impair any right consequent thereon. No course of dealing between the Company
and any holder of Notes nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any of such holder's rights under
this Agreement or the Notes. As used herein, the term "this Agreement" and
references thereto shall mean this Agreement as it may from time to time be
amended or supplemented.

                                  ARTICLE XVIII

                                     NOTICES

            All notices and communications provided for hereunder shall be in
writing and sent by (a) telecopy if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), (b) registered or certified mail with return receipt
requested (postage prepaid) or (c) a recognized overnight delivery service (with
charges prepaid). Any such notice must be sent:

      at the beginning hereof to the attention of SCOTT D. SULLIVAN AND SUSAN
      MAYER, or at

      such other address or attention party as you shall have specified to the
      Company in writing.

      set forth on the records of the Company.

            (iii) if to the Company, to the Company at its address set forth at
      the beginning hereof to the attention of TIMOTHY ADAMS AND LINDA KOKAL, or
      at such other address or attention party as the Company shall have
      specified to you in writing.

Unless otherwise specified in this Agreement, the effective date of any notice
or request given in connection with this Agreement will be deemed given only
when the addressee actually receives it.

                                   ARTICLE XIX

                            REPRODUCTION OF DOCUMENTS

            This Agreement and all documents relating thereto, including (a)
consents, modifications and waivers that may hereafter be executed, (b)
documents received by you on the Closing Date (except the Notes themselves) and
(c) financial statements, certificates and other information previously or
hereafter furnished to you, may be reproduced by you by any photographic,
photostatic, microfilm, microcard, miniature photographic or other similar
process and you may destroy any original document so reproduced. The Company
agrees and stipulates that, to the extent permitted by applicable law, any such
reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by you in the regular
course of business), and any enlargement, facsimile or further reproduction of
such reproduction shall likewise be admissible in evidence. This Article XIX
shall not prohibit the Company from contesting any such reproduction to the same
extent that it could contest the original, or from introducing evidence to
demonstrate the inaccuracy of any such reproduction.

                            CONFIDENTIAL INFORMATION

            For the purposes of this Article XX, "CONFIDENTIAL INFORMATION"
means non-public information delivered to you by or on behalf of the Company or
any of its Subsidiaries in connection with the transactions contemplated by or
otherwise pursuant to this Agreement (or information provided to you in
connection with the Merger and any other transactions contemplated in connection
with the Merger Agreement) that is proprietary in nature; PROVIDED that such
term does not include any information or matter that (a) at the time of
disclosure or thereafter is generally known by the public (other than as a
result of its disclosure by you or your respective representatives in breach of
this Article XX), (b) was or becomes available to you on a nonconfidential basis
from a Person who is not known by you to be bound by a confidentiality agreement
with the Company prohibiting disclosure thereof or (c) is independently
developed by you or your representatives. You will maintain the confidentiality
of such Confidential Information in accordance with procedures adopted by you in
good faith to protect confidential information of third parties delivered to
you; PROVIDED that you may deliver or disclose Confidential Information to (i)
your affiliates, directors, officers, employees, advisors, agents, bank or
institutional lenders, controlling persons or representatives thereof (to the
extent such disclosure reasonably relates to the administration of the
investment represented by your Notes and it being understood that prior to such
disclosure any such Person will be informed of the confidential nature of the
Confidential Information and shall agree to be bound by this Article XX and that
you agree to be responsible for any breach of this Article XX by any such
Person), (ii) any other holder of any Note, (iii) any Institutional Investor to
which you sell or offer to sell such Note or any part thereof or any
participation therein (if such Person has agreed in writing prior to its receipt
of such Confidential Information to be bound by the provisions of this Article
XX), (iv) any Person from which you offer to purchase any security of the
Company (if such Person has agreed in writing prior to its receipt of such
Confidential Information to be bound by the provisions of this Article XX), (v)
any federal or state regulatory authority having jurisdiction over you, (vi) the
National Association of Insurance Commissioners, any similar organization or any
nationally recognized rating agency that requires access to information about
your investment portfolio, (vii) any other Person to whom such Confidential
information must be disclosed pursuant to applicable law; PROVIDED, with respect
to clauses (v), (vi) and (vii), that you agree to (A) immediately notify the
Company of the existence, terms and circumstances surrounding the request or
requirement for disclosure pursuant to applicable law and (B) consult with the
Company on the advisability of taking legally available steps to resist or
narrow such request with respect to any other Person to which such delivery or
disclosure may or may not be necessary or appropriate or (viii) if an Event of
Default has occurred and is continuing, to the extent you may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under your Notes
and this Agreement. Each holder of a Note, by its acceptance of a Note, will be
deemed to have agreed to be bound by and to be entitled to the benefits of this
Article XX as though it were a party to this Agreement.

                                   ARTICLE XXI

                            SUBSTITUTION OF PURCHASER

            You shall have the right, at any time or from time to time, to cause
any of your Affiliates to pay the Purchase Price on the Purchase Date or to
substitute (each such instance, a "SUBSTITUTION") any of your Affiliates as a
purchaser of some or all of the Notes that you have agreed to purchase
hereunder, by written notice to the Company, which notice shall (i) be
substantially in the form set out in EXHIBIT IV, (ii) be signed by both you and
such Affiliate, (iii) contain such Affiliate's agreement to be bound by this
Agreement and (iv) contain a confirmation by such Affiliate of the accuracy with
respect to it of the representation set forth in Article VI. Upon receipt of
each such notice, wherever the word "you" is used in this Agreement (other than
in this Article XXI), such word shall be deemed to refer to each such Affiliate
in lieu of you to the extent commensurate with each such Substitution. If and to
the extent that any such Affiliate is so substituted as a purchaser hereunder
and such Affiliate thereafter transfers (each such instance, a "TRANSFER") to
you all of the Notes then held by such Affiliate, upon receipt by the Company of
notice of such transfer, wherever the word "you" is used in this Agreement
(other than in this Article XXI), such word shall no longer be deemed to refer
to such Affiliate but shall refer to you, and you shall have all the rights of
an original holder of the Notes under this Agreement, in each case to the extent
commensurate with each such Transfer.

                                  ARTICLE XXII

                                  MISCELLANEOUS

            SECTION 22.01. WAIVER OF FACILITIES COMMITMENT. The annual "Digex
Minimum Commitments" contained in Section 5 and in Paragraph 3 of Schedule 1 to
the Master Facilities Agreement dated as of January 1, 2001, between MCI
WorldCom Network Services, Inc. and the Company shall be waived, and the Company
shall not be obligated to purchase any minimum level of service thereunder, as
of the Closing Date and shall remain in effect whether or not this Agreement
remains in effect.

            SECTION 22.02. OPTIONAL AMENDMENT. (a) You will review any funding
request with respect to the Company's 2003 business plan following the Company's
submission of such plan to your Board of Directors but will have no obligation
to provide funding in connection therewith.

            (b) If at any time an Approved Business Plan is rescinded or
materially amended, revised or updated, you shall have no obligation to provide
any funds to the Company following such change in excess of that required prior
to such change unless and until the Boards of Directors of the Company and you,
acting reasonably, shall each have approved a new such business plan or such
change, as applicable.

            SECTION 22.03. ASSIGNMENT. This Agreement, or any interest herein
other than any ownership interest in any Note, may not be assigned, in whole or
in part, by

<Page>
                                                                              39

either party without the prior written consent of the other party, which shall
not be unreasonably withheld. Notwithstanding the foregoing, you may assign this
Agreement, in whole or in part, to an Affiliate or, on or after December 31,
2002, a third party, PROVIDED that any such assignment to an Affiliate shall not
relieve you of your funding obligations if such Affiliate fails to fulfill them,
and PROVIDED FURTHER that such assignment shall not violate any Federal
securities laws.

            SECTION 22.04. SUCCESSORS AND ASSIGNS. All covenants and other
agreements contained in this Agreement by or on behalf of any of the parties
hereto bind and inure to the benefit of their respective successors and assigns
(including any subsequent holder of a Note), whether so expressed or not.

            SECTION 22.05. PAYMENTS DUE ON NON-BUSINESS DAYS. Anything in this
Agreement or the Notes to the contrary notwithstanding, any payment of principal
of or interest on any Note that is due on a date other than a Business Day shall
be made on the next succeeding Business Day including the additional days
elapsed in the computation of the interest payable on such next succeeding
Business Day.

            SECTION 22.06. SEVERABILITY. Any provision of this Agreement that 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; such provision shall be deemed
deleted and replaced by a valid and enforceable provision that so far as
possible achieves the same objection as the severed provision; and any such
prohibition or unenforceability in any jurisdiction shall (to the full extent
permitted by law) not invalidate or render unenforceable such provision in any
other jurisdiction.

            SECTION 22.07. CONSTRUCTION. Each covenant contained herein shall be
construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant. Where any provision herein refers to action
that any Person is to take, or that such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

            SECTION 22.08. COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be an original but all of which
together shall constitute one instrument. Each counterpart may consist of a
number of copies hereof, each signed by less than all, but together signed by
all, of the parties hereto.

            SECTION 22.09. GOVERNING LAW. This Agreement shall be subject to,
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the law of the State of New York excluding choice-of-law
principles of the law of such State that would require the application of the
laws of a jurisdiction other than such State.

            SECTION 22.10. JURISDICTION AND CONSENT TO SERVICE OF PROCESS. (a)
For resolution of any dispute that is not resolved by the Company and you in
accordance with the immediately preceding Section, including any action or

or proceeding relating to this Agreement against the Company or its properties
in the courts of any jurisdiction.

            (b) The Company hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it

process in the manner provided for notices in Article XVIII. Nothing in this
Agreement will affect the right of the Company or you to serve process in any
other manner permitted by law.

OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.
