entered into on this 29th day of July, 1999 by and among STATE COMMUNICATIONS,
INC., a South Carolina corporation (the "Company"), and each of the purchasers
named in Schedule I attached hereto (collectively, the "Purchasers" and each,
individually, a "Purchaser").

                              W I T N E S S E T H:

         WHEREAS, the Purchasers desire to purchase from the Company, and the

share, constituting an aggregate purchase price of $49,449,993.75.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein, the parties agree as follows:


                                    ARTICLE I
                      SUBSCRIPTION FOR THE PREFERRED SHARES

         1.1 Purchase and Sale. Subject to the terms and conditions set forth
herein, each Purchaser hereby subscribes for and agrees to purchase from the
Company, and the Company hereby agrees to issue and sell to each Purchaser, on
the Closing Date (as hereinafter defined), the number of Preferred Shares set
forth opposite such Purchaser's name in column A of Schedule I, for a purchase
price of $3.75 per share to be paid as follows:

                  (i) On the Closing Date, each Purchaser shall deliver to the

         forth opposite such Purchaser's name in column C of Schedule I; and

                  (ii) deliver to the Company evidence of the cancellation or
         satisfaction of the principal amount of the debt owed to such Purchaser
         by the Company in the amount set forth opposite such Purchaser's name

the business of providing local exchange and long distance telecommunication
services to residential customers and the small business market (the

Company's ability to perform its obligations in any material respect under the
Documents, as such term is defined in Section 2.2 hereof (a "Material Adverse
Effect"). Schedule 2.1(b) identifies each jurisdiction in which the Company and
each Subsidiary is currently qualified to do business as a foreign corporation.

                  (c) The Company has delivered to Purchasers' counsel true and
complete copies of the Articles of Incorporation and Bylaws of the Company,

"Articles of Amendment"). Except for (i) the Articles of Amendment; (ii)
Articles of Amendment regarding the Designations, Rights and Preferences of the
Series A Convertible Preferred Stock; and (iii) the amendment of the Bylaws to
reflect the terms of the Documents, the Articles of Incorporation and Bylaws of
the Company will not be amended prior to the Closing Date.

                  (d) The Company and the Subsidiaries have all corporate power
and all governmental licenses, authorizations, consents and approvals required
to carry on the Business as now being conducted and necessary to own, operate
and lease their properties and assets.

         2.2 Corporate Power. The Company has the requisite corporate power to
execute and deliver this Agreement, the Amended and Restated Stockholders'
Agreement, in substantially the form attached hereto as Exhibit B (the
"Stockholders' Agreement"), the Registration Rights Agreement in substantially
the form attached hereto as Exhibit C (the "Registration Rights Agreement")
(this Agreement, the Stockholders' Agreement and the Registration Rights
Agreement shall be collectively referred to herein as the "Documents") and to
perform its obligations hereunder and thereunder.

         2.3 Validity; Binding Obligation. This Agreement has been duly
authorized, executed and delivered by the Company and constitutes a valid and
binding agreement of the Company, enforceable against it in accordance with its
terms. The other Documents have each been duly authorized by the Company and,
when executed and delivered by the Company and the other parties named therein,
will constitute valid and binding agreements of the Company, enforceable against
the Company in accordance with their respective terms. The issuance, sale and
delivery of the Preferred Shares have been, or prior to the Closing Date will
be, duly authorized by all necessary corporate action by the Company.

         2.4 Financial Statements. (a) Schedule 2.4(a) contains a true and

                  of the Company for the year ended December 31, 1998; and

                  stockholders' equity and cash flows of the Company for such

<PAGE>   9

the required footnotes or normal recurring year-end adjustments) applied on a

Statements are correct and complete and present fairly the financial position of
the Company at the date of the balance sheets included therein and the results
of operations and cash flows of the Company for the respective periods covered
by the statements of operations and cash flows included therein. Except as set

the ordinary course of business which in the aggregate have not been materially
adverse, and (ii) none of the business, prospects, financial condition,
operations, property or affairs of the Company has been materially and adversely
affected by any occurrence or development, individually or in the aggregate,
whether or not covered by insurance.

         2.5 Consents. No consent, approval or authorization of, or
qualification, designation, declaration or filing with, or notice to any
governmental authority on the part of the Company is required in connection with
(i) the valid execution and delivery of the Documents, and (ii) the offer, sale
or issuance of the Preferred Shares (and the Common Stock issuable upon
conversion of the Preferred Shares), except (A) the filing of the Articles of
Amendment in the Office of the Secretary of State of South Carolina, which
filing will be accomplished on or prior to the Closing Date, (B) the filing of a
Form D with the Securities and Exchange Commission, (C) the qualification (or
taking such action as may be necessary to secure an exemption from

the Common Stock issuable upon conversion of the Preferred Shares) under any
applicable state securities laws, which qualification, if required, will be
accomplished in a timely manner prior to or promptly upon completion of the
Closing, as required by such laws and (D) such consents, approvals and
authorizations as have been obtained by the Company prior to Closing.

         2.6 Capitalization. (a) The authorized capital stock of the Company
consists of 50,000,000 shares of Common Stock, $.001 par value (the "Common
Stock"), and 20,000,000 shares of Preferred Stock, $.01 par value (the
"Preferred Stock"), 4,791,668 of which have been designated as Series A
Convertible Preferred Stock (the "Series A Preferred Stock") and 14,133,329 of
which have been designated as Series B Convertible Preferred Stock. Immediately
after the Closing, (i) 11,133,253 shares of Common Stock will be issued and
outstanding, (ii) 4,711,672 shares of Series A Preferred Stock will be issued
and outstanding, (iii) 13,186,665 shares of Series B Preferred Stock will be
issued and outstanding, (iv) 4,951,747 options, warrants or other rights to
purchase or otherwise acquire shares of Common Stock will be outstanding, and
(v) such number of shares of Common Stock as shall be necessary to effect the
conversion of the Preferred Stock will be reserved for future issuance upon
conversion of Preferred Stock. Immediately after the Closing upon receipt of the
Purchase Price, all such issued and outstanding shares of capital stock of the
Company will be duly authorized and validly issued and outstanding, fully paid
and nonassessable.

                  (b) Schedule 2.6(b) contains a true and correct copy of the
Company's current stock transfer ledger reflecting the record holders of the
Company's equity securities and the number of shares held of each. Each of
Shaler P. Houser and Charles L. Houser (individually, a "Founder" and
collectively, the "Founders") is the lawful owner, of record and beneficially,
of the number of shares of Common Stock set forth opposite the name of each
Founder on Schedule 2.6(b). Each Founder has



                                      -5-
<PAGE>   10

good and marketable title to, and all other incidents of record and beneficial
ownership of, such shares, free and clear of any liens, claims and encumbrances,
other than the restrictions set forth in the Stockholders' Agreement or the
Liquidation Proceeds Agreements attached to Schedule 2.6(b) (the "Liquidation
Agreements").

                  (c) Except as set forth in paragraph (a) above or as disclosed
on Schedule 2.6(b), immediately after the Closing, there will be no outstanding
(i) securities convertible into or exchangeable for shares of capital stock of
the Company, (ii) options, warrants or other rights to purchase or otherwise
acquire from the Company shares of such capital stock, or securities convertible
into or exchangeable for shares of such capital stock, or (iii) contracts,
agreements or commitments relating to the issuance by the Company of any shares
of such capital stock, any such convertible or exchangeable securities, or any
such options, warrants or other rights. Except for the Stockholders' Agreement,
the Liquidation Agreements or the Investment Agreement by and among Seruus
Telecom Fund, L.P., the Company and certain individuals named therein, dated
February 19, 1998, there are no voting trusts, voting agreements, proxies or
other agreements, instruments or understandings with respect to the voting of
the capital stock of the Company to which the Company or, to the Company's
knowledge, any of its stockholders is a party.

                  (d) The Company has reserved, and at all times from and after
the date hereof will keep reserved, free from preemptive rights, out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the Preferred Shares, sufficient shares of Common
Stock to provide for the conversion of all Preferred Shares.

         2.7 Validity and Rights of Preferred Shares. The Preferred Shares, when
issued to the Purchasers pursuant to this Agreement, will be validly issued,
fully paid and nonassessable, and will have the designations, preferences,
limitations, and relative rights set forth in the Articles of Amendment. Any and
all shares of Common Stock issued upon conversion of the Preferred Shares (the
"Conversion Shares"), when issued, will be validly issued, fully paid and
nonassessable.

         2.8 Registration Rights. Except for the rights granted under the
Registration Rights Agreement and except as set forth in the Amended and
Restated Registration Rights Agreement dated February 19, 1998 between the
Company and Seruus Telecom Fund, L.P. and the Registration Rights Agreement
dated May 27, 1999 between the Company and Nortel Networks Inc., no person or
entity has any right to cause the Company to effect the registration under the
Securities Act of 1933, as amended (the "Securities Act"), of any shares of its
capital stock.

         2.9 Securities Laws. Subject to the accuracy of the representations and
warranties of the Purchasers contained in Article III hereof, the offering, sale
and purchase of the Preferred Shares contemplated hereby are exempt from
registration under the Securities Act. The issuance of all other shares of
capital stock of the Company on or before the date hereof is being or has been
made in compliance with the Securities Act and all applicable state securities
or blue sky laws. All offering documents used and oral disclosure made in
connection with the offer or sale of any of the Company's securities prior to
the date hereof have been correct in all material respects and have not

its respective leasehold interests, in each case subject to no mortgage, pledge,
lien, encumbrance or charge, other than as set forth on Schedule 2.13 hereto.
Schedule 2.13 accurately lists with respect to the personal property owned (or
purported to be owned) by the Company or the Subsidiaries (i) each financing
statement, deed, agreement or other instrument which has been filed, recorded or
registered pursuant to any United States federal, state or local law or
regulation that names the Company or a Subsidiary as debtor or lessee or as the

the conduct



                                      -7-

of the Business as now conducted and as proposed to be conducted, and is in
compliance in all material respects with the terms and conditions, if any, of
all such copyrights, trademarks, service marks, trade names, patents and
intellectual property licenses and the terms and conditions of any agreements
relating thereto. Except as set forth on Schedule 2.14, there are no outstanding
options, licenses, or material agreements of any kind relating to the foregoing,
nor is the Company or any Subsidiary bound by or a party to any options,
licenses or agreements of any kind with respect to the patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information,
proprietary rights and processes of any other person or entity. Neither the
Company nor any Subsidiary has received any communications alleging that it has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity. To the Company's
knowledge, none of its employees are obligated under any contract (including
licenses, covenants or commitments of any nature) or other agreement, or subject
to any judgment, decree or order of any court or administrative agency, that
would interfere with the use of their best efforts to promote the interests of
the Company or any Subsidiary or that would conflict with the Company's business
as proposed to be conducted. Neither the execution nor delivery of this
Agreement, nor the carrying on of the Company's or any Subsidiary's business by
the employees of the Company, nor the conduct of the Company's or any
Subsidiary's business as proposed, will conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any of such employees is now
obligated. It is not currently and will not in the future be necessary for the
Company to utilize any inventions of any of its employees (or people it
currently intends to hire) made prior to their employment by the Company.

         2.15 Compliance with Other Instruments. Neither the Company nor any
Subsidiary is in violation of or in default under any term of its organizational
documents, any term or provision of any mortgage, indenture, contract,
agreement, instrument, judgment or decree, nor is in violation of any applicable
order, statute, rule or regulation except for such violations or defaults as are
not expected to have a Material Adverse Effect, and to the Company's knowledge
there is no state of facts which, with the passage of time or giving of notice
or both, would constitute any such violation or default that would in the
aggregate have a Material Adverse Effect. The execution, delivery and
performance of and compliance with the Documents, the issuance of the Preferred
Shares (and the Conversion Shares) and the consummation of any other transaction
contemplated by the Documents have not resulted and will not result in any such
violation, or be in conflict with, or constitute a default under any of the
foregoing, or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Company or any Subsidiary.

         2.16 Compliance with Law. Each of the Company and the Subsidiaries is
in compliance with all statutes, laws and ordinances and all governmental rules
and regulations to which it is subject, the violation of which, either
individually or in the aggregate, would have a Material Adverse Effect. Neither
the execution, delivery or performance of this Agreement or the other Documents
nor the consummation of the transactions contemplated by the Documents will
cause the Company or any Subsidiary to be in violation of any law or ordinance,
or any order, rule or regulation, of any federal, state, municipal or other
governmental or public authority or agency.

                  action would, in the reasonable opinion of counsel, constitute

                           (ii) to make copies and take extracts from any
                  thereof, except for information which is confidential or

foregoing sentence, it is understood and agreed by the Company that all
reasonable expenses incurred by the Company or such Subsidiary, any officers,
employees or agents thereof or the independent certified public accountants
therefor, shall be expenses payable by the Company and shall not be expenses of
the Purchaser making the inspection.

         7.7 Other Information. The Company shall deliver the following to each
such Purchaser, provided that in the reasonable opinion of counsel to the

                  Company, copies of any detailed reports (including the

restricted or prohibited from holding any of the shares of capital stock of the
Company (including any shares of capital stock or other securities distributable
to such Purchaser in any merger, reorganization, readjustment or other

actions necessary to comply with such Regulatory Requirement, and the Company
shall take all steps necessary to comply with such determination as
expeditiously as possible. This Section 9.9 shall not be deemed to limit in any
respect the representations of the Purchasers in Sections 3.2 and 3.4 hereof
