         3.1 ORGANIZATION, GOOD STANDING AND QUALIFICATION. Each of the Company
and its Subsidiaries is a corporation duly organized, validly existing and in
good standing under the

hereto (the "Security Agreement" and together with this Agreement, the

Agreements"), to issue and sell the Securities and to carry out the provisions
of this Agreement and the Related Agreements. Each of the Company and its
Subsidiaries is duly qualified and is authorized to do business and is in good
standing as a foreign corporation in all jurisdictions in which the nature of
its activities and of its properties (both owned and leased) makes such
qualification necessary, except for those jurisdictions in which failure to do
so would not have a material adverse effect on the business, operations or
financial condition of the Company and its Subsidiaries, taken as a whole.

         3.2 SUBSIDIARIES. Except for Birch Telecom of Missouri, Inc., Birch
Telecom of Kansas, Inc., Birch Telecom of Nebraska, Inc. and Birch Telecom of
Arizona, Inc. (each a "Subsidiary" and collectively, the "Subsidiaries"), the

or similar entity. All the outstanding shares of stock of the Subsidiaries have
been validly issued and are fully paid and non-assessable and all such
outstanding shares are owned directly by the Company free of any lien or claim.
Neither the Company nor any of its Subsidiaries is a participant in any joint
venture, partnership or similar arrangement.

         3.3 CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of the
Company, immediately prior to the Closing, will consist of 52,000,000 shares, of
which 27,000,000 shares of Common Stock, par value $.001 per share, 1,800,000
shares of which are issued and outstanding and 3,687,500 shares of which are
reserved for future issuance to employees pursuant to the Stock Option Plan (as
hereinafter defined) and 25,000,000 shares of Preferred Stock, par value $.001
per share, 2,968,750 of which are designated Series A Preferred Stock, none of
which are issued and outstanding; 8,125,000 of which are designated Series B
Preferred Stock, none of which are issued and outstanding; 8,050,000 shares of
which are designated Series C Preferred Stock, none of which are issued and
outstanding. All issued and outstanding shares of the Company's capital stock
(a) have been duly authorized and validly issued, (b) are fully paid and
nonassessable, (c) were issued in compliance with all applicable state and
federal laws concerning the issuance of securities. The rights, preferences,
privileges and restrictions of the Preferred Stock are as stated in the Restated
Certificate. A copy of the Company's Stock Option Plan is attached hereto as
Exhibit E (the "Stock Option Plan"). Other than the 3,687,500 shares reserved
for issuance under the Stock Option Plan and the Existing Warrants, and except
as may be granted pursuant to this Agreement and the Related Agreements, there
are no outstanding options, warrants, rights (including conversion or preemptive
rights and rights of first refusal), proxy or shareholder agreements, or
agreements of any kind for the purchase or acquisition from the Company of any
of its securities. When issued in compliance with the provisions of this
Agreement and the Restated Certificate, the Series B Preferred Shares, the
Series C Preferred Shares, and Common Shares will be validly issued, fully paid
and


                                       5.

nonassessable; provided, however, that such shares may be subject to
restrictions on transfer under state and/or federal securities laws as set forth
herein or in the Purchasers Rights Agreement or as otherwise required by such
laws at the time a transfer is proposed. After giving effect to the transactions
contemplated by the Merger Agreement (as hereinafter defined) and this
Agreement, the capitalization of the Company as of the First Closing and as of
the Second Closing (assuming all 1,906,250 shares of Series B Preferred Stock
are issued and sold) would be as set forth on Schedules V and VI, respectively.

         3.4 AUTHORIZATION; BINDING OBLIGATIONS. All corporate action on the
part of the Company, its officers, directors and shareholders necessary for the
authorization of this Agreement and the Related Agreements, the performance of
all obligations of the Company hereunder and thereunder as of a Closing and the

action on Purchaser's part required for the lawful execution and delivery of

Purchaser hereby represents and warrants as follows:

                  (a) PURCHASER BEARS ECONOMIC RISK. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Securities are registered pursuant to
the Securities Act, or an exemption from registration is available. Purchaser
understands that the Company has no present intention of registering the
Securities or any Underlying Securities. Purchaser also understands that there
is no assurance that any exemption from registration under the Securities Act
will be available and that, even if available, such exemption may not allow
Purchaser to transfer all or any portion of the Securities under the
circumstances, in the amounts

or at the times Purchaser might propose.

                  (b) ACQUISITION FOR OWN ACCOUNT. Purchaser is acquiring the
Securities for Purchaser's own account for investment only, and not with a view
towards their distribution.

                  (c) PURCHASER CAN PROTECT ITS INTEREST. Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement, and the Related Agreements.
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.

                  (d) ACCREDITED INVESTOR. Purchaser represents that it is an

Financial Statements and has had an opportunity to discuss the Company's
business, management and financial affairs with directors, officers and
management of the Company and has had the opportunity to review the Company's
operations and facilities. Purchaser has also had the opportunity to ask
questions of and receive answers from, the Company and its management regarding
the terms and conditions of this investment.

                  (f) RULE 144. Purchaser acknowledges and agrees that the
Securities must be held indefinitely unless they are subsequently registered
under the Securities Act or an exemption from such registration is available.
Purchaser has been advised or is aware of the provisions of Rule 144 promulgated
under the Securities Act as in effect from time to time, which permits limited
resale of shares purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things: the availability of certain
current public information about the Company, the resale occurring following the
required holding period under Rule 144 and the number of shares being sold
