                   AGREEMENT FOR TELECOMMUNICATION SERVICES


          THIS AGREEMENT is entered into by and between KNOLOGY HOLDINGS, INC.
with offices located in West Point, Georgia (hereinafter "Customer") and
ITC*DELTACOM COMMUNICATIONS, INC., an Alabama corporation with offices located
in West Point, Georgia, (hereinafter "ITC*DeltaCom"), collectively referred to
as the "Parties", and shall be effective on the date last appearing below.

          WHEREAS, Customer desires to purchase certain telecommunication
services from DeltaCom; and

          WHEREAS, ITC*DeltaCom desires to provide Customer with certain
telecommunication services.

NOW THEREFORE, in consideration of the mutual promises and covenants contained
herein, ITC*DeltaCom and Customer agree as follows:

          1.   TERM:  The term of this Agreement shall commence on the date of
signature and continue for a period of twelve (12) consecutive months. Upon
expiration of the term hereof, this Agreement shall be continued month to month
thereafter, with either Party having the right to terminate this Agreement by
giving Sixty (60) days prior written notice to the other.

          2.   SERVICES PROVIDED BY ITC*DELTACOM:  Subject to the terms and
conditions of this Agreement, ITC*DeltaCom shall provide certain long distance
telecommunications services (the "Services") to Customer as further described
in Attachment 1. Both parties agree that the services provided herein which are
subject to regulation by any governmental entity, agency or commission shall be
provided in accordance with the governmental entity's, agency's, or commission's
rules and regulations and ITC*DeltaCom's current approved tariff and as the
same may be amended from time to time. All charges for usage of the services to
be provided by ITC*DeltaCom, or by Customer to its customers, hereunder shall
not exceed the maximum limit charges established by order or ruling of any
governmental agency or entity from time to time, if any such limits are
established.

          3.   RATES:  The rates applicable to the Services provided to
Customer by ITC*DeltaCom are contained in Attachment 1.1.

          4.   PAYMENT FOR SERVICES:  A statement for Services provided to
Customer under this Agreement shall be submitted to Customer by ITC*DeltaCom on
a monthly basis and shall be due and payable on the due date stated therein
(which shall not be earlier than thirty (30) days after Customer's receipt of
the statement). The first and the final statement for Services will be for a
partial month in the event the service dates do not coincide with ITC*DeltaCom
billing dates. Payments received more than ten (10) days from the due date will
be considered delinquent and will bear interest at the rate of one and one half
percent (1.5%) per month or at the maximum rate allowed by law, whichever is
less, on any sum remaining delinquent.  Customer shall be responsible for
payment to ITC*DeltaCom for all excise, sales, use and other similar taxes
which may be levied by any governing body for Service furnished under this
Agreement. All statements shall be deemed to be correct and binding upon
Customer unless written notice is provded to ITC*DeltaCom of any disputed
charges within six (6) months of the date of the statement. In no event does
such notice excuse Customer from making payment within the time provided
herein.


                                       1
<PAGE>   2
         5.  SUSPENSION OF SERVICE FOR NONPAYMENT: ITC*DeltaCom may suspend
Service ten (10) days after mailing or telefaxing written notice to Customer of
nonpayment of any sum fifteen (15) or more days past the statement due date (but
only if the Customer does not cure the non-payment within the ten (10) day
period). Following a suspension of Service(s), ITC*DeltaCom may terminate the
Service(s) to Customer, in whole or in part, without further notice to Customer,
if nonpayment is not corrected with five (5) days of suspension of Service.
Neither suspension nor termination of the Service will relieve Customer of any
obligation to pay ITC*DeltaCom's statement(s) for Services. Should this
Agreement be terminated by Customer prior to the expiration of the term of this
Agreement, Customer shall be responsible for payment of all reasonable costs,
charges, and expenses incurred by ITC*DeltaCom resulting from the early
termination of this Agreement.

         6.  SECURITY FOR PAYMENT: Upon request by ITC*DeltaCom, Customer
agrees to provide financial statements and/or other indications of financial
circumstances.

         7.  COMPLIANCE WITH ADMINISTRATIVE PROCEDURES: Customer shall comply
with the administrative procedures of ITC*DeltaCom which have been previously
delivered to Customer, and as the same may be amended from time to time by
mutual agreement of the parties in writing, regarding providing of
documentation and information necessary for ITC*DeltaCom to provide the
Services described herein to Customer.

         8.  BRANDING OF CALLS: Customer shall be responsible for assuring that
for billing purposes all Services provided hereunder shall be branded in the
name of Customer and that Customer's customers and any other end users to whom
the Services are offered by Customer are informed that the Services provided
and rates charged the customer and end user are rates established by Customer.

         9.  CANCELLATION: Either Party shall have the right to cancel this
Agreement without liability if ITC*DeltaCom is prohibited from furnishing the
Service or if any material rate or term contained herein is materially
adversely changed by order of the highest court of competent jurisdiction to
which the matter is appealed, the Federal Communications Commission, or any
other federal, state, or local government authority.

         10. USE AND PROTECTION OF INFORMATION: The parties agree that the terms
of this Agreement or any modifications hereto and any information exchanged
between them, except information which is in the public domain, in any form, is
confidential information ("Confidential Information"). The Parties agree that
during the term of this Agreement and for a period of three (3) years
thereafter, they will not, without the prior written consent of the disclosing
Party: (i) use any portion of such Confidential Information for any purpose
other than performance pursuant to this Agreement; or (ii) disclose any portion
of such Confidential Information to a third party; provided, however, that the
recipient may disclose Confidential Information to the extent such disclosure is
required either by a governmental or regulatory authority or to enforce its
rights under this Agreement. The obligations to protect Confidential Information
shall remain in effect except to the extent that such Confidential Information
(a) becomes generally available to the public other than as a result of
unauthorized disclosure by the recipient Party, (b) has been released without
similar restriction by the disclosing Party to another person or entity, (c) was
known by the recipient Party prior to disclosure or (d) was independently

agrees to safeguard Confidential Information utilizing the same degree of care
utilized by the recipient Party in protecting its own confidential information.

         11.   LIMITATION OF LIABILITY AND DISCLAIMER OF WARRANTY: IN NO EVENT
SHALL ITC*DELTACOM BE LIABLE TO CUSTOMER, OR ANY END USER OR ANY OTHER PARTY,
PERSON OR ENTITY FOR DIRECT, INDIRECT, CONSEQUENTIAL, SPECIAL, INCIDENTAL,
PUNITIVE, OR ANY OTHER FORM OF DAMAGES, OR FOR ANY LOST PROFITS OF ANY KIND OR
NATURE WHATSOEVER, ARISING OUT OF MISTAKES, ACCIDENTS, ERRORS, OMISSIONS,
INTERRUPTIONS, LOST DATA, CLAIMS OF THIRD PARTIES, OR DEFECTS IN TRANSMISSION,
OR DELAYS, INCLUDING THOSE WHICH MAY BE CAUSED BY REGULATORY OR JUDICIAL
AUTHORITIES OR OTHERWISE, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
OBLIGATIONS OF ITC*DELTACOM PURSUANT TO THIS AGREEMENT, WHETHER IN CONTRACT OR
TORT, INCLUDING NEGLIGENCE AND OTHERWISE. ITC*DELTACOM MAKES NO WARRANTY,
WHETHER EXPRESS, IMPLIED OR STATUTORY, AS TO THE DESCRIPTION, QUALITY,
MERCHANTABILITY, COMPLETENESS OR FITNESS FOR ANY PURPOSE OF THE SERVICE OR THE
LOCAL ACCESS, OR AS TO ANY OTHER MATTER ALL OF WHICH WARRANTIES BY ITC*DELTACOM
ARE HEREBY EXCLUDED AND DISCLAIMED. For purposes of this Paragraph, the term
"ITC*DeltaCom" shall be deemed to include ITC*DeltaCom Communications, Inc.,
its parent entity, affiliates, and subsidiaries.

         12.   NO THIRD-PARTY BENEFICIARIES: This Agreement is for the sole
benefit of the parties hereto and their respective permitted successors and
assigns, and shall not be construed as granting rights to any person or entity
other than the parties or imposing on either party obligations to any person or
entity other than a party.

         13.   INDEMNITY:  (A) Each Party, its officers, agents or employees
engaged in performance under this Agreement shall at no time be deemed to be
performing as agents or employees of the other Party, or as joint venturers,
and any acts, errors or omissions of such officers, agents and employees shall
not be deemed to be those of the other Party. (B) Each Party shall indemnify
and hold the other and/or all of its officers, agents, servants, parent,
subsidiaries and employees ("Affiliates") or any of them, harmless from and
against any and all losses, claims, damages, liabilities, costs, and expenses
("Claims") imposed upon either Party (including without limitation damages to
property or injuries, including death, to Affiliates, employees or
subcontractors, and all other persons performing this Agreement) as a result of
a negligent act or omission on the part of the indemnifying Party, its
Affiliates, or subcontractors in connection with the performance of this
Agreement or as a result of a breach or default of any covenant of the
indemnifying Party under this Agreement.

         14.   FORCE MAJEURE: Except as provided in this Agreement, either Party
may delay performance hereunder due to causes beyond its reasonable control,
including but not limited to acts of God, fire, explosion, vandalism, cable
cut, storm or other similar catastrophes; any law, order, regulation,
direction, action or request of the United States government, or of any other
government, including state and local governments, having jurisdiction over
either of the parties, or of any department, agency, commission, court, bureau,
corporation or other instrumentality of any one or more of said governments, or
of any civil or military authority; national emergencies; insurrections; riots;
wars; or strikes, lock-outs, work stoppages or other labor difficulties. If
such delay in performance shall be on the part of ITC*DeltaCom and shall be for
more than thirty (30) days, then Customer may terminate this Agreement with no
liability on the part of any Party. The affected Party shall use its best
efforts to remove the cause of the delay.

         15.   ASSIGNMENT:  This Agreement is not assignable by either Party
without the prior written consent of the other Party, which consent shall not
be unreasonably withheld, and any attempt to assign any of the rights, duties or
obligations of this Agreement without such consent is void. Notwithstanding the
foregoing, either Party may assign any rights, duties, or obligations of this
Agreement to a parent, subsidiary or affiliate, or any successors in interest
created by merger, divestiture, or reorganization without the written consent of
the other Party. It shall be a condition precedent to any permitted assignment
that the assignee shall execute a counterpart of this Agreement, thereby
becoming a Party to this Agreement and agreeing to be bound by all of the terms
and provisions hereof. Either Party may assign and pledge its interest under
this Agreement as security for indebtedness without the other Party's written
consent.

         16.   ADDITIONAL PROVISIONS:

         (A)   The failure of either Party to give notice of default or to
enforce or insist upon compliance with any terms or conditions of this
Agreement, the waiver of any term or condition of this Agreement, or the
granting of an extension of time for performance, shall not constitute the
permanent waiver of any term or condition of this Agreement, and this Agreement
and each of its provisions shall remain at all times in full force and effect
until modified by the parties in writing.

         (B)   Each Party agrees to comply with, and shall require its agents,
servants, employees and contractors to comply with all applicable laws, rules,
regulations and orders of all governmental and quasi-governmental agencies
having jurisdiction over such Party or its telecommunication services and to
obtain and maintain in effect all permits, licenses, approvals, and agreements
that are needed to operate its telecommunication services and perform its
obligations under this Agreement.

         (C)   In event suit is brought or an attorney is retained by any Party
to this Agreement to enforce the terms of this Agreement or to collect any
moneys due hereunder or to collect money damages for breach hereof, the
prevailing Party shall be entitled to recover, in addition to any other remedy,
reimbursement for reasonable attorney's fees, court costs, costs of
investigation and other related expenses incurred in connection therewith. All
suits brought by either Party must be commenced within one (1) year of the
action on which the claim is based, or less if so required by Alabama law.

         (D)   No subsequent agreement between Customer and ITC*DeltaCom
concerning the Services shall be effective or binding unless it is made in
writing, and no representation, promise, inducement or statement or intention
has been made by either Party which is not embodied herein.

         (E)   This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors or assigns; provided,
however, neither Party may assign or transfer its right or obligations under
this Agreement without prior written consent of the other Party, which consent
shall not be unreasonably withheld.

         (F)   Notices under this Agreement shall be in writing and delivered
by overnight express courier service or by registered or certified mail, return
receipt requested, postage paid, to the person whose names and business
addresses appear herein, or as otherwise provided by proper notice hereunder,
