          3.6  Financial Statements; Interim Changes. The Company's unaudited
balance sheet as of April 30, 1997 (the "Latest Balance Sheet") and unaudited
statements of income and cash flows of the Company for the period from inception
to April 30, 1997 delivered to the Purchasers in connection with the investment
contemplated hereby have been prepared in accordance with generally accepted
accounting principles consistently applied (subject to normal year-end
adjustments and the absence of footnote disclosures) and fairly present in all
material respects the proforma financial position and the results of operations
of the Company for the period covered thereby, and the Company has no material
liabilities or obligations of any nature (absolute, accrued, contingent or
otherwise) that are not either reflected or fully reserved against on the Latest
Balance Sheet or incurred in the ordinary course of the business of the Company
subsequent to the date thereof. Since the date of the Latest Balance Sheet,
there has not been any material adverse change in the business, operations,
financial condition or prospects of the Company (other than the consummation of
the Mergers).

          3.7  Compliance with Laws. The Company's business, including the
business of Cypress Communications, L.L.C. conducted prior to the Merger, has
been conducted in compliance with all applicable laws and regulations of
governmental authorities, except for such violations that have been cured or
that, individually or in the aggregate, may not reasonably be expected to have a
material adverse effect on the business, operations, financial condition or
prospects of the Company.

          3.8  Proprietary Rights. The Company has not received any
communications alleging that it has violated or, by conducting its business as
proposed would violate, any proprietary rights of any other person, and except
as set forth on Schedule 3.8, the Company is not aware of any basis for the
                ------------
foregoing.


          3.9  Actions Pending. There is no action, suit or proceeding pending
or, to the best knowledge of the Company, threatened against or affecting the

<PAGE>

          3.10  Material Contracts.  Except as set forth on Schedule 3.10
                                                            -------------
attached hereto, the Company is not a party to (and is not otherwise bound by)
any of the following: (i) any employment or consulting contract, (ii) any
agreement providing for the issuance or repurchase of any securities of the
Company, (iii) any agreement in respect of registration rights, preemptive
rights, rights of first refusal, voting rights or other rights of security
holders (other than the Stockholders Agreement), (iv) any agreement evidencing
or providing for any indebtedness for borrowed money, or (v) any other agreement
that could reasonably be deemed material to the Company.

          3.11  Investments in United States Real Property Interests.  The
Company's capital stock does not constitute a United States real property
interest as that term is defined in Section 897(c)(1)(A)(ii) of the Internal
Revenue Code of 1986, as amended (the "Code"). The preceding representation is
based on a determination by the Company that the Company is not and has never
been a United States real property holding corporation (as that term is defined
in Section 897(c)(2) of the Code). From time to time, upon request of any
Purchaser, the Company shall make a determination as to its status as a United
States real property holding corporation ("USRPHC"). If at any time in the
future the Company should become a USRPHC, the Company shall, as promptly as
possible, notify each Purchaser of such change in status.

          3.12  Unrelated Business Taxable Income. Any gross income derived by
the Purchasers from the Company shall be in the form of dividends and capital
gains and losses from the disposition of the stock of the Company.

          3.13  Qualified Small Business. The Company qualifies as a "Qualified
Small Business" as defined in Section 1202(d) of the Code and covenants that so
long as its shares are held by the Purchasers (or a transferee in whose hands
the shares are eligible to qualify as Qualified Small Business Stock as defined
in Section 1202(c) of the Code), it will use its best efforts to cause the
shares to qualify as Qualified Small Business Stock.

          3.14  Mergers. That certain Agreement and Plan of Merger of Cypress
Communications, L.L.C., a Georgia limited liability company, with and into
Cypress Communications, Inc., a Delaware corporation, dated as of the date of
this Agreement, and that certain Agreement and Plan of Merger of CV Cypress
Corp., a Colorado Corporation, Cypress Alta Investor Corp., a Massachusetts
Corporation, with and into Cypress Communications, Inc., a Delaware corporation,
dated as of the date of this Agreement, are each legal, valid, binding,
enforceable, and in full force and effect under the laws of the States of
Delaware, Georgia, Colorado and Massachusetts, as the case may be, pursuant to
which the Company continues as the surviving entity (the "Mergers").

     4.   Representations and Warranties Of The Purchasers

     Each Purchaser severally and not jointly hereby represents and warrants to
the Company as follows:

                                       4
<PAGE>

               4.1  Requisite Power and Authority. Such Purchaser has all
     necessary power and authority under all applicable provisions of law to
     execute and deliver this Agreement and to carry out its provisions. All
     actions on such Purchaser's part required for the lawful execution and
     delivery of this Agreement have been or will be effectively taken prior to
     the Closing.

               4.2  Investment Representations. Such Purchaser understands that
     neither the Shares nor the Conversion Shares have been registered under any
     state securities act or the Securities Act of 1933, as amended (the
     "Securities Act"). Such Purchaser also understands that the Shares are
     being offered and sold pursuant to an exemption from registration contained
     in applicable state securities acts and the Securities Act based in part
     upon the Purchaser's representations contained in this Agreement.

                    (a)  Purchaser Bears Economic Risk. Such Purchaser has
     substantial experience in evaluating and investing in private placement
     transactions of securities in companies similar to the Company so that
     Purchaser is capable of evaluating the merits and risks of its or his
     investment in the Company and has the capacity to protect its or his own
     interests. Such Purchaser must bear the economic risk of this investment
     indefinitely unless the Shares (or the Conversion Shares) are registered
     pursuant to the Securities Act, or an exemption from registration is
     available. Such Purchaser understands that the Company has no present
     intention of registering the Shares, the Conversion Shares or any shares of
     its Common Stock. Such 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
     such Purchaser to transfer all or any portion of the Shares or the
     Conversion Shares under the circumstances, in the amounts or at the times
     such Purchaser might propose. Such Purchaser can bear the economic risk of
     losing its entire investment in the Company.

                    (b)  Acquisition for Own Account. Such Purchaser is
     acquiring the Shares and the Conversion Shares for Purchaser's own account
     for investment only, and not with a view towards their resale or
     distribution in violation of applicable securities laws.

                    (c)  Purchaser Can Protect Its or His Interest. Such
     Purchaser represents that, by reason of Purchaser's or of its management's
     business or financial experience, such Purchaser has the capacity to
     protect its or his own interests in connection with the transactions
     contemplated in this Agreement. Further, such Purchaser is aware of no
     publication of any advertisement in connection with the transactions
     contemplated by the Agreement.

                    (d)  Individual Purchaser Consideration. To the extent
     Purchaser is an individual:

                                       5

<PAGE>

                               (i) Such Purchaser has discussed the suitability
of the investment in the Company for its particular tax and financial situation
with its legal, tax, and financial advisors to the extent Purchaser deems
appropriate, and has neither received nor relied upon any advice of any person
or persons acting for or on behalf of the Company. All information which
Purchaser has provided to the Company concerning itself and its financial
position is currently correct and complete.

                               (ii) Such Purchaser's overall commitment to
investments which are not readily marketable is not disproportionate to its net
worth, and its investment in the Shares and Conversion Shares will not cause
this overall commitment to become excessive.

                               (iii) Such Purchaser has adequate means of
providing for its current needs and personal contingencies and has no need for
the Shares or Conversion Shares to be liquid.

                               (iv) Such Purchaser is purchasing the Shares for
the purpose of deriving an economic profit without regard to tax benefits.

                        (e) Accredited Investor. Such Purchaser represents that
Purchaser is an accredited investor within the meaning of Regulation D under the
Securities Act.

                        (f) Company Information. Such Purchaser has had an
opportunity to discuss the Company's business, management and financial affairs
with directors, officers and management of the Company. Such 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.
Purchaser has had an adequate opportunity to inspect and copy all material
documents relating to the Company, and to obtain any additional information that
is necessary to verify the accuracy of the information the Purchaser has
received. Purchaser has not received any information from nor has Purchaser
relied upon the name or reputation of any law firm or accounting firm that the
Company or any persons acting on its behalf may have mentioned as being involved
in this sale or as being the Company's legal counsel or accounting firm.

                        (g) Rule 144. Such Purchaser acknowledges and agrees
that the Shares and the Conversion Shares must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Such Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act, 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 not less than one year after a party has purchased and paid for the
security to be sold, the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act

                                       6
<PAGE>

     of 1934, as amended) and the number of shares being sold during any three-
     month period not exceeding specified limitations.

                    (h)  Risks. Such Purchaser acknowledges that an investment
     in the Company involved many risks, and understands all of the risk factors
     related to an investment in the Company, including, but not limited to the
     following:

                         (i)   The Company was recently formed and does not have
     a significant operating history upon which an evaluation of the Company's
     performance could be based. There can be no assurance that the Company's
     operations will be profitable or that the Company will be able to sell its
     products and services. The likelihood of success of the Company is
     speculative, and the Purchaser is familiar with the many problems,
     difficulties, complications and delays frequently encountered in the
     operation and development of early stage and expanding businesses.

                         (ii)  Additional proceeds will be required to finance
     the activities of the Company. The Company will need financing for
     operations, production and marketing. No arrangements have been made to
     secure such financing, and there can be no assurance that such additional
     financing will be available when required or on terms acceptable to the
     Company.

                         (iii) The telecommunications industry has been
     characterized by steady technological change, frequent new service
     introductions and evolving industry standards. The Company's success will
     depend in part on its ability to anticipate such changes and to offer
     responsive services on a timely basis. Further, although the trend has been
     toward decreases in the cost of equipment, there is no assurance that this
     trend will continue, or that the Company will be able to respond
     successfully to such changes.

                         (iv)  The telecommunications industry is highly
     regulated. Certain aspects of the Company's plan will require authorization
     from the Federal Communications Commission ("FCC") and applicable state
     public service commissions. This involves both obtaining the required
     authorizations and complying with the on-going requirements imposed on
     carriers, such as filing a tariff. No assurances can be given that there
     will be no opposition to the Company's applications or that the necessary
     authorizations (other than any such authorization necessary to continue the
     current business operations of the Company) will be granted. Additional
     expenses (such as legal and accounting fees) will be involved in attempting
     to obtain and in maintaining these authorizations and in complying with the
     accounting reporting and administrative regulations imposed by the FCC and
     the state commissions. The cost for access to local service could change
     significantly as deregulation of the local loop progresses and carriers
     other than the existing local exchange carriers are authorized to provide
     local service.

                         (v)   The Company competes with a number of competitors
     with significantly greater financial resources than the Company.

                                       7
<PAGE>

                    (vi)   Two of the Company's initial agreements with building
owners grant such owners the right to terminate the agreement for a specific
period.

                    (vii)  The Company's success will be related to the real
estate cycle, in particular, to construction and leasing activity.

                    (viii) The Company's operations will depend upon contractual
arrangements with local exchange and long distance carriers. The costs
associated with the purchase of local exchange services, access to the long
distance network, and long distance services could change significantly as
deregulation of the local loop progresses, carriers other than the existing
local exchange carriers are authorized to provide local exchange service and
access to long distance, and the costs of long distance carriers change in
response. The Company believes it will have a number of options for obtaining
both exchange and access services at competitive rates, however the continuing
availability of alternative resources cannot be assured.

                    (ix)   The Company recently began using both MCI
Communications and WorldCom to provide outbound local service in place of
BellSouth. Though the Company believes that this change of vendors has the
potential to reduce its cost of local service, there is an element of
operational risk associated with offering service from new vendors, as well as
risks of tenant acceptance.

                    (x)    A search done in the process of preparing to apply
for a trademark for the name of the Company revealed potential conflicts with
the Company's use of the trade name "Cypress" and the Company's ability to
obtain trademark protection for this name. The Company has decided that it is
not in the Company's best interest to apply for a trademark in the name of
Cypress Communications or to change the name of the Company at this time.
Furthermore, there is a possibility that one of the firms with whom there is a
potential conflict, or other companies for that matter, will demand that the
Company discontinue using the name Cypress Communications. Such a demand might
result in either expensive litigation and/or a change the Company's name, which
in either event, could have a material adverse effect on the Company.

               (i)  Residence. The address of such a Purchaser as set forth on
Exhibit A attached hereto is its true and correct principal place of business
or, in the case of a Purchaser that is an individual, his residence. Such
Purchaser does not have any present intention of becoming a resident of any
other state or jurisdiction.

     5.   Conditions Precedent To Purchasers' Obligations

          The obligation of each Purchaser to purchase and pay for the Shares to
be delivered to it at the Closing shall be subject to the satisfaction of the

closing of the transactions contemplated hereby. All statements as to factual

contemplated hereby shall be deemed to be representations and warranties by the

injunctive relief in the event of any such breach.

          7.6   Separability.  In case any provision of the Agreement shall be
