a Disability and shall have returned to work after the end of such Disability,
any Disability commencing within sixty (60) days after the termination of the
prior Disability shall be deemed to be a continuation of the prior Disability,
and the periods of all such Disabilities shall be added as if they fell on
consecutive days.

            7.3 TERMINATION BY THE COMPANY FOR CAUSE. The Executive's employment
hereunder may be terminated by the Company for Cause (as hereinafter defined)

      of any covenant, promise, representation or warranty of this Agreement or
      any fiduciary or other obligation owed by the Executive to the Company,
      including, without limitation, the obligation to refrain from engaging in
      the activities prohibited by Sections 8 and 9 hereof; or

            (c) Gross misconduct, including, but not limited to, the willful
      failure of the Executive either to (i) continue to obey lawful written
      instructions of the Board of Directors of the Company (that do not involve
      matters which, if obeyed by the Executive, would permit the Executive to
      terminate his employment for "Good Reason," as defined in subsection 7.5
      hereof) after receiving thirty (30) days notice in writing of the
      Employee's failure to do so and the Company's intention to terminate the
      Executive if such failure is not corrected, or (ii) correct any conduct of
      the Executive which constitutes a material breach of this Agreement after
      receiving thirty (30) days notice in writing of the Executive's failure to
      do so and the Company's intention to terminate Executive if such failure
      is not corrected. This cure right may be exercised on only one occasion
      during each calendar year of the Term.

            7.4 TERMINATION BY THE COMPANY WITHOUT CAUSE. The Executive's
employment hereunder may be terminated by the Company for any reason, or for no
reason whatsoever, by giving notice of such termination (the "Company's Notice")
to the Executive, which termination shall be effective as of the end of the day
on the later of (i) the thirtieth (30th) day after the Executive's receipt of

termination under this subsection 7.4 without the need for any notice on the
part of the Company. Until the effective date of such termination (without
giving effect to the last sentence of this subsection 7.4), the Executive shall
be obligated to continue to perform the Services at all times; provided,
however, the Company reserves the right, exercisable by giving notice to the
Executive (within the Company's Notice or otherwise), to require the Executive
to cease performing the Services at any time on or after delivery of the
Company's Notice to the Executive. In the event that, prior to the effective
date of termination set forth above in this subsection 7.4, the Executive ceases
performing the Services, other than at the Company's request (as described
above), then such termination shall be deemed effective as of the end of the day
on the date that the Executive ceases performing the Services.

            7.5 TERMINATION BY THE EXECUTIVE. The Executive's employment
hereunder may be terminated by the Executive for any reason, or for no reason
whatsoever, by giving notice of such termination (the "Executive's Notice") to
the Company, which termination shall be effective as of the end of the day on
the later of (i) the thirtieth (30th) day after the Company's receipt of the
Executive's Notice, or (ii) such later date, if any, specified by the Executive
therein, unless such effective date is accelerated (1) by the Company as
provided below or (2) pursuant to the third sentence of this subsection 7.5.
Until the effective date of such termination (without giving effect to the third
sentence of this subsection 7.5), the Executive shall be obligated to continue
to perform the Services at all times; provided, however, the Company reserves
the right, exercisable by giving notice to the Executive, to accelerate the
effective date of termination pursuant to this subsection 7.5 to any date on or
after the thirtieth (30th) day after the Company's receipt of the Executive's
Notice. In the event that, prior to the effective date of termination set forth
above in this subsection 7.5, the Executive ceases performing the Services,
other than as a result of the Company's acceleration of the effective date (as
described above), then such termination shall be deemed effective as of the end
of the day on the date that the Executive ceases performing the Services. If the
Executive terminates his employment, as provided above and states in his notice
of termination Good Reason for the termination, then such termination shall be
effective immediately. For purposes hereof, "GOOD REASON" shall mean the

(ii) insolvency of the Company; (iii) a reduction by the Company in the
Executive's annual base salary as then in effect; (iv) a new Company requirement

compensation is due, unless such failure to pay is reasonably in dispute by the
Company.

The Executive's right to terminate his employment pursuant to this subsection
shall not be affected by his incapacity due to physical or mental illness. The
Executive's continued

                                      -5-

employment shall not constitute consent to, or a waiver of rights with respect
to, any circumstance constituting Good Reason hereunder.

            7.6 EFFECT OF TERMINATION OF EMPLOYMENT.

                  (a) Upon the effective date of termination of the Executive's
      employment hereunder for any reason, the Executive shall be deemed to have
      automatically resigned from any and all directorships, offices or other
      positions (fiduciary or otherwise) that the Executive may then hold in
      connection with the Company or Cypress or in connection with any employee

      deemed effective without the requirement that a written resignation be
      delivered by the Executive. Further, upon the effective date of
      termination of the Executive's employment hereunder for any reason, all
      debts, obligations and liabilities (whether or not contingent) of the
      Executive to the Company shall be immediately due and payable to the
      Company and may be offset, at the Company's sole option, against any
      amounts due and owing by the Company to the Executive. From and after the
      effective date of the termination of the Executive's employment hereunder
      for any reason, the Executive shall not at any time represent himself
      still to be connected, or to have any connection, with the Company or
      Cypress.

                  (b) If the Company terminates the Executive's employment
      without Cause pursuant to subsections 7.1, 7.2 or 7.4 or if the Executive
      terminates his employment for Good Reason pursuant to subsection 7.5
      hereof, the Company (i) shall continue to pay to the Executive the
      Executive's then current base salary with the Company, in accordance with
      the Company's payroll policies, for a period of six (6) months following
      the date of termination, and (ii) shall provide Executive with benefits
      coverage, including, without limitation, coverage under medical, dental
      and vision, but excluding disability plans for a period of six (6) months
      following the date of termination. If the Company terminates the
      Executive's employment without Cause pursuant to subsections 7.1, 7.2 or
      if the Executive terminates his employment for Good Reason pursuant to
      subsection 7.5 hereof, the Company shall accelerate Executive's stock
      options, if any, subject to any deductions or offsets described in this
      Agreement. Except as provided in the immediately preceding two sentences,
      from and after the effective date of the termination of the Executive's
      employment hereunder, the Company shall not have any further obligations
      under this Agreement or otherwise with respect to the Executive or his
      employment hereunder, except for the Company's obligation to pay to the
      Executive (or the estate of the Executive in the event of termination
      pursuant to subsection 7.1 hereof) all earned and accrued but unpaid
      salary through the effective date of termination of the Executive's
      employment hereunder, subject to any deductions or offsets described in
      this Agreement.

                  (c) Notwithstanding the foregoing, the Company shall continue
      to have all rights available to the Company under this Agreement,
      including, without limitation, all rights under Sections 8, 9, 10 and 11
      hereof, at law or in equity, and the provisions of this Agreement shall
      survive the termination of the Executive's

                                      -6-
<PAGE>

      employment hereunder to the extent required to give full effect to the
      covenants and agreements contained herein.

      8. TERMINATION UPON A CHANGE IN CONTROL.

            8.1 CHANGE OF CONTROL. For purposes of this Agreement, a "Change in
Control" shall mean (a) the time that any person and all other persons who
constitute a group (within the meaning of Section 13(d)(3) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), have acquired within any
12 month period (i) direct or indirect beneficial ownership (within the meaning
of Section 13(d)(3) under the Exchange Act) of 51% or more of the Company's
outstanding securities or (ii) assets of the Company having a fair market value
in excess of one-third of the Company's total assets, (b) the first day on which
a majority of the members of the Company's Board are not continuing directors,
or (c) upon the occurrence of a merger, consolidation, acquisition of property
or stock, separation, reorganization or liquidation of the Company, as a result
of which the stockholders of the Company receive cash, stock or other property
in exchange for their shares of Company stock (but not a public offering of
stock by the Company), and the Company is not the surviving entity. However,
these Change in Control provisions shall not become effective if a technical
Change in Control is met purely due to the Company's financing activities.

            8.2 EFFECT OF CHANGE IN CONTROL. In the event of Employee's
termination of employment coincident with a Change in Control, whether at
Employee's direction or otherwise, Employee shall immediately be paid all
accrued salary, bonus compensation to the extent earned, vested deferred
compensation (other than plan benefits which will be paid in accordance with the
applicable plan), any benefits under any plans of the Company in which Employee
is a participant to the full extent of Employee's rights under such plans
(including accelerated vesting of any awards granted to Employee under the
Company's stock incentive plans, which shall provide for accelerated vesting),
accrued vacation pay and any appropriate business expenses incurred by Employee
in connection with his duties hereunder, all to the date of termination. The
Company (i) shall continue to pay to the Executive the Executive's then current
salary with the Company, in accordance with the Company's payroll policies, for
a period of six (6) months following the date of termination, (ii) shall provide
Executive with benefits coverage, including, without limitation, coverage under
medical, dental and vision, but excluding disability plans for a period of six
(6) months following the date of termination and (iii) shall accelerate one
hundred percent (100%) of the Executive's stock options, if any, subject to any
deductions or offsets described in this Agreement. If Executive's employment is
terminated prior to the date on which a Change in Control event occurs, and such
termination was at the request of a third party who has taken steps to effect a
Change in Control event or was otherwise caused by the Change in Control event,
then for all purposes of this Agreement, a Change in Control event shall be
deemed to have occurred prior to such termination.

call upon, any customer or prospective customer of the Company, or any
representative of any customer or prospective customer of the Company, with a
view to the sale or provision of any product or service competitive or

Term and the last two (2) years thereof; provided that the restrictions set
forth in this sentence shall apply only to customers or prospective customers of
the Company, or representatives of customers or prospective customers of the
Company, with which the Executive had material contact at any time during the
shorter in duration of the Term and the last two (2) years thereof. "Material
contact" exists between Executive and each of the Company's existing customers:
(i) with whom Executive actually dealt; or (ii) whose dealings with the Company
were handled, coordinated or supervised by Executive.

            10.3 NONSOLICITATION OF EXECUTIVES AND INDEPENDENT CONTRACTORS. At
all times during the Term and for a period of two (2) years thereafter, the
Executive will not directly or indirectly solicit or encourage any employee or
independent contractor of the Company to leave such employment or engagement

former employee or independent contractor of the Company, unless such former
employee or independent contractor of the Company shall have ceased to be so
employed or engaged by the Company for a period of at least one (1) year
immediately prior to such action by the Executive.

      Notwithstanding the provisions of this Section 10, if the Company

hereof or if the Executive terminates with Good Reason pursuant to subsection
7.5 hereof, the obligations of the Executive under subsections 9.1, 9.2 and 9.3
shall expire ninety (90) days after the termination of Executive's employment

      11. CONSTRUCTION. The Executive acknowledges and agrees that the covenants
and agreements contained in Sections 9 and 10 of this Agreement are of the
essence of this Agreement, and that each of such covenants and agreements is
reasonable and necessary to protect and preserve the interests and business of
the Company. The Executive further acknowledges and agrees that: (1) each of
such covenants and agreements is separate, distinct and severable, not only from
the other of such covenants and agreements, but also from the remaining
provisions of this Agreement, (ii) the unenforceability of any such covenants or
agreements shall not affect the validity or enforceability of any other such
covenants or agreements or any other provision or provisions of this Agreement,
and (iii) in the event any court of competent jurisdiction or arbitrator, as
applicable, determines, rules or holds that any such covenant or agreement
hereof is overly broad or against the public policy of the state, then said
court or arbitrator, as the case may be, is specifically authorized to reform
and narrow said covenant or agreement to the extent necessary to make said
reformed and narrowed covenant or agreement valid and enforceable.

      12. REMEDIES. It is specifically understood and agreed that (i) any breach
of any of the provisions of Section 9 or 10 of this Agreement is likely to
result in irreparable injury to the Company, (ii) the remedy at law alone will
be an inadequate remedy for such breach, and (iii) in addition to any other
remedy it may have for such breach, the Company shall be entitled to enforce the
specific performance of this Agreement by the Executive and to seek both
temporary and permanent injunctive relief (to the extent permitted by law)
without the necessity of proving actual damages. Notwithstanding any other
provision of this Agreement to the contrary, any and all obligations of the
Company to pay any compensation to the Executive for any reason shall cease and
terminate upon the material breach by the Executive of any of the obligations of
the Executive under Sections 8 or 9 of this Agreement.

      13. EXISTING RESTRICTIVE COVENANTS AND INDEMNIFICATION. The Executive
represents and warrants that (i) the Executive is not a party to or subject to
any outstanding contract, agreement or order whereby the Executive is prohibited
from entering into this Agreement, or any outstanding restrictive covenant or
noncompetition agreement which would interfere with or prevent the Executive's
employment hereunder as contemplated by this Agreement; (ii) the Executive has
performed any and all duties or obligations that he may have under any contract
or agreement with a former employer or other party, including, without
limitation, the return of all confidential materials; and (iii) the Executive is
currently not in possession of any confidential materials or property belonging
to any such former employer or other party. The Executive acknowledges and
agrees that he shall advise the Company in the event that his duties with the
Company should be changed or enlarged in such a manner as to conflict with any
such prior contract, agreement, order or restrictive covenant. Without
limitation on any other rights or remedies available to the Company with respect
to the Executive's breach of his obligations hereunder, the Executive shall
defend, indemnify and hold the Company, the Affiliates, and each of their
respective shareholders, officers, directors, employees, counsel, agents,
affiliates and assigns (collectively, the "COMPANY INDEMNITEES") harmless from
and against any and all direct or indirect demands, claims, payments,
obligations, recoveries, deficiencies, fines, penalties, assessments, actions,
causes of action, suits, losses, diminution in the value of assets of the
Company, compensatory, punitive, exemplary or consequential damages (including,
without

                                      -11-

limitation, lost income and profits and interruptions of business), liabilities,
costs, expenses, and interest on any amount payable to a third party as a result
of the foregoing, whether accrued, absolute, contingent, known, unknown or
otherwise asserted against, imposed upon or incurred by the Company Indemnitees,
or any of them, by reason of or resulting from, arising out of, based upon or
otherwise in respect of (1) any conflict between the Executive's employment
hereunder and any prior employment, duty, contract, express or implied
agreement, order or restrictive covenant, or (2) any misrepresentation by the
Executive hereunder as to any facts which are the subject matter of any conflict
or violation of any prior contract, agreement, order or restrictive covenant on
the part of the Executive.

being referred to herein as such Lender's "TERM LOAN COMMITMENT"). Repayments
and prepayments of the Term Loan shall not be subject to reborrowing. In
connection with the making of the Term Loans, U.S. RealTel, Inc., shall issue to
the Lenders warrants to purchase four hundred thousand (400,000) shares of
common stock, par value $0.001 per share of U.S. RealTel, Inc., with an exercise
price of $1.13 per share as allocated among the Lenders set forth on Schedule
2.1 hereto under the heading "Warrant Shares" which warrants shall be
exercisable upon the issuance thereof for a period of ten (10) years.

      2.2 EVIDENCE OF DEBT. The Term Loan and the Loans made by each Lender to
Borrowers thereunder shall be evidenced by a term note (each, a "TERM NOTE")
payable to the order of such Lender, which note shall be in the form attached
hereto as Exhibit B in an amount equal to such Lender's Term Loan Commitment.

      2.3 AMOUNT AND MAINTENANCE OF LOAN. The Term Loan will be made and

date of such advance of the Loan to the day of repayment of such advance.
Interest shall be computed on the basis of a year of 360 days and actual days
elapsed and shall be payable as provided in Section 3.2. In no contingency or
event whatsoever shall the rate or amount of interest paid by Borrowers under
this Agreement or any of the Ancillary Agreements exceed the maximum amount

such Lender shall apply such excess to any unpaid principal owed by Borrowers to
such Lender or, if the amount of such excess exceeds the unpaid balance of such
principal, such Lender shall promptly refund such excess interest to Borrowers
and (ii) the provisions of this Agreement shall be deemed amended to provide for
such permissible rate. All sums paid, or agreed to be paid, by Borrowers which

      of the respective dates of such balance sheets that are not reflected
      therein or in the notes thereto.

      7.11 SECTION TITLES, ETC. The section titles and table of contents, if
any, contained in this Agreement are and shall be without substantive meaning or
content of any kind whatsoever and are not a part of the agreement between the
parties hereto. All Exhibits and Schedules which are referred to herein or
attached hereto are incorporated by reference.

      7.12 OLIVER LENDERS. Each of the Oliver Lenders hereby agree that any
single trustee of any of such trusts, acting alone, shall be authorized on
behalf of the Oliver Lenders to take any action on the Oliver Lenders' behalf as
may be permitted to be taken or required to be taken by the Lender under the
provisions of this Agreement and each Ancillary Agreement. Borrowers consent to
the provisions of this Section 7.12.

      7.13 TAX TREATMENT. Borrowers and each of the Lenders shall mutually agree
upon of the treatment of the Term Loans, the Loan Fees and the Warrants for tax
purposes within ninety days of the date hereof. Following such determination,
Borrowers and Lenders shall cause all tax returns and financial statements
(including any amended returns or claims for refund) filed by any of them to be
consistent with such allocation.

8.    CROSS-GUARANTY.

      8.1 CROSS-GUARANTY. Each Borrower hereby agrees that such Borrower is
jointly and severally liable for, and hereby absolutely and unconditionally
guarantees to each Lender and their respective successors and assigns, the full
and prompt payment (whether at stated maturity, by acceleration or otherwise)
and performance of, all Liabilities owed or hereafter owing to each Lender by
each other Borrower. Each Borrower agrees that its guaranty obligation hereunder
is a continuing guaranty of payment and performance and not of collection, that
its obligations under this Section 8 shall not be discharged until payment and
performance, in full, of the Liabilities has occurred, and that its obligations
under this Section 8 shall be absolute and unconditional, irrespective of, and
unaffected by, the genuineness, validity, regularity, enforceability or any
future amendment of, or change in, this Agreement, any other Ancillary Agreement
or any other agreement, document or instrument to which any Borrower is or may
become a party; the absence of any action to enforce this Agreement (including
this Section 8) or any other Ancillary Agreement or the waiver or consent by
each Lender with respect to any of the provisions thereof; the existence, value
or condition of, or failure to perfect

                                       27
<PAGE>

its Lien against, any security for the Liabilities or any action, or the absence
of any action, by each Lender in respect thereof (including the release of any
such security); the insolvency of any Borrower; or any other action or
circumstances that might otherwise constitute a legal or equitable discharge or
defense of a surety or guarantor. Each Borrower shall be regarded, and shall be
in the same position, as principal debtor with respect to the Liabilities
guaranteed hereunder.

      8.2 WAIVERS BY BORROWERS. Each Borrower expressly waives all rights it may
have now or in the future under any statute, or at common law, or at law or in
equity, or otherwise, to compel any Lender to marshal assets or to proceed in
respect of the Liabilities guaranteed hereunder, against any other party or
against any security for the payment and performance of the Liabilities before
proceeding against, or as a condition to proceeding against, such Borrower. It
is agreed among each Borrower and each Lender that the foregoing waivers are of
the essence of the transaction contemplated by this Agreement and the Ancillary
Agreements and that, but for the provisions of this Section 8.2 and such
waivers, the Lenders would decline to enter into this Agreement.

      8.3 BENEFIT OF GUARANTY. Each Borrower agrees that the provisions of this
Article 8 are for the benefit of each Lender and their respective successors,
transferees, endorsees and assigns, and nothing herein contained shall impair,
as between any other Borrower or any Lender, the obligations of such other
Borrower under this Agreement and the Ancillary Agreements.

      8.4 SUBORDINATION OF SUBROGATION, ETC. Notwithstanding anything to the
contrary in this Agreement or in any Ancillary Agreement, and except as set
forth in Section 8.7, each Borrower hereby expressly and irrevocably
subordinates to payment of the Liabilities any and all rights at law or in
equity to subrogation, reimbursement, exoneration, contribution, indemnification
or set off and any and all defenses available to a surety, guarantor or
accommodation co-obligor until the Liabilities are indefeasibly paid in full in
cash. Each Borrower acknowledges and agrees that this subordination is intended
to benefit each Lender and shall not limit or otherwise affect such Borrower's
liability hereunder or the enforceability of this Section 8.4, and that each
Lender and their respective successors and assigns are intended third party
beneficiaries of the waivers and agreements set forth in this Section 8.4.

      8.5 ELECTION OF REMEDIES. If any Lender may, under applicable law, proceed
to realize its benefits under this Agreement or any Ancillary Agreement giving
such Lender a Lien upon any Collateral, whether owned by any Borrower or by any
other Person, either by judicial foreclosure or by non-judicial sale or
enforcement, any Lender may, at its sole option, determine which of its remedies
or rights it may pursue without affecting any of its rights and remedies under
this Section 8. If, in the exercise of any of its rights and remedies, any
Lender shall forfeit any of its rights or remedies, including its right to enter
a deficiency judgment against any Borrower or any other Person, whether because
of any applicable laws pertaining to "election of remedies" or the like, each
Borrower hereby consents to such action by such Lender and waives any claim
based upon such action, even if such action by such Lender shall result in a
full or partial loss of any rights of subrogation that each Borrower might
otherwise have had but for

                                       28
<PAGE>

such action by such Lender. Any election of remedies that results in the denial
or impairment of the right of any Lender to seek a deficiency judgment against
any Borrower shall not impair any other Borrower's obligation to pay the full
amount of the Liabilities. In the event any Lender shall bid at any foreclosure
or trustee's sale or at any private sale permitted by law or this Agreement or
any Ancillary Agreements, such Lender may bid all or less than the amount of the
Liabilities and the amount of such bid need not be paid by such Lender but shall
be credited against the Liabilities. The amount of the successful bid at any
such sale, whether such Lender or any other party is the successful bidder,
shall be conclusively deemed to be the fair market value of the Collateral and
the difference between such bid amount and the remaining balance of the
Liabilities shall be conclusively deemed to be the amount of the Liabilities
guaranteed under this Section 8, notwithstanding that any present or future law
or court decision or ruling may have the effect of reducing the amount of any
deficiency claim to which any Lender might otherwise be entitled but for such
bidding at any such sale.

      8.6 LIMITATION. Notwithstanding any provision herein contained to the
contrary, each Borrower's liability under this Section 8 (which liability is in
any event in addition to amounts for which such Borrower is primarily liable
under Section 2) shall be limited to an amount not to exceed as of any date of
determination the greater of: (i) the net amount of all Loans advanced to any
other Borrower under this Agreement and then re-loaned or otherwise transferred
to, or for the benefit of, such Borrower; and (ii) the amount that could be
claimed by Lenders from such Borrower under this Section 8 without rendering
such claim voidable or avoidable under Section 548 of Chapter 11 of the
Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act,
Uniform Fraudulent Conveyance Act or similar statute or common law after taking
into account, among other things, such Borrower's right of contribution and
indemnification from each other Borrower under Section 8.7.

      8.7 CONTRIBUTION WITH RESPECT TO GUARANTY OBLIGATIONS. To the extent that
any Borrower shall make a payment under this Section 8 of all or any of the
Liabilities (other than Loans made directly to that Borrower) (a "GUARANTOR
PAYMENT") that exceeds the amount such Borrower would otherwise have paid if
each Borrower had paid the aggregate Liabilities satisfied by such Guarantor
Payment in the same proportion that such Borrower's "Allocable Amount" (as
defined below) (as determined immediately prior to such Guarantor Payment) bore
to the aggregate Allocable Amounts of each of the Borrowers as determined
immediately prior to the making of such Guarantor Payment, then, following
indefeasible payment in full in cash of the Liabilities and termination of the
Commitments) such Borrower shall be entitled to receive contribution and
indemnification payments from, and be reimbursed by, each other Borrower for the
amount of such excess, pro rata based upon their respective Allocable Amounts in
effect immediately prior to such Guarantor Payment. As of any date of
determination, the "ALLOCABLE AMOUNT" of any Borrower shall be equal to the
maximum amount of the claim that could then be recovered from such Borrower
under this Section 8.7 without rendering such claim voidable or avoidable under
Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state
Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar
statute or common law. This Section 8.7 is intended only to define the relative
rights of Borrowers and nothing set forth in this Section 8.7 is intended to or
shall impair the obligations of Borrowers, jointly and severally, to pay any
amounts as and

                                       29
<PAGE>

when the same shall become due and payable in accordance with the terms of this
Agreement, including Section 8.7. Nothing contained in this Section 8.7 shall
limit the liability of any Borrower to pay the Loans made directly or indirectly
to that Borrower and accrued interest, fees and expenses with respect thereto
for which such Borrower shall be primarily liable. The parties hereto
acknowledge that the rights of contribution and indemnification hereunder shall
constitute assets of the Borrower to which such contribution and indemnification
is owing. The rights of the indemnifying Borrowers against other Borrower under
this Section 8.7 shall be exercisable upon the full and indefeasible payment of
the Liabilities and the termination of the commitments by the Lenders.

      8.8 LIABILITY CUMULATIVE. The liability of Borrowers under this Section 8
is in addition to and shall be cumulative with all liabilities of each Borrower
to each Lender under this Agreement and the Ancillary Agreements to which such
Borrower is a party or in respect of any Liabilities or obligation of the other
Borrowers, without any limitation as to amount, unless the instrument or
agreement evidencing or creating such other liability specifically provides to
the contrary.

                                   Litigation

Stephen Baron v. Cypress Communications, Inc., et al., Case No. SC 070743, filed
February 11, 2002, before the Superior Court of the State of California for the
County of Los Angeles West District. Stephen Baron is a former customer who has
filed a complaint that includes claims for breach of contract, fraud, negligent
misrepresentation, negligence, and restitution of payments obtained under
duress. Cypress has responded to written discovery requests to Plaintiff for the
production of documents, and Cypress intends to serve written discovery requests
upon Plaintiff shortly. Plaintiff has noticed Roy Cantu and Rosie Gonzalez for
deposition during the week of June 18, 2002. Plaintiff's attorney made a
settlement offer of $35,000 to which we counter offered with $3,000. Given the
current posture of the case, assessment of the likelihood of a materially
adverse outcome is not possible.

RealTel de Argentina, S.A. was involved in mediation with Gabriel Mauricio Melzi
regarding payment of $150,000 owed for the acquisition of his shares in this
entity. A recent settlement was reached and as soon as the Issuer receives the
settlement agreement, it will pay $131,190 to Mr. Melzi.
