                                   SECTION 12
                                    REMEDIES

         12.1     If a warranty or representation given by the Funds in ss. 11
                  is incorrect at the Signing Date or at the Closing ("BREACH OF
                  WARRANTY"), the Funds shall indemnify Purchaser against the

                  incurred by Purchaser as follows: (i) in the event the Loss
                  suffered is attributable to a diminution in the value of the

                  shall be indemnified by the Sellers shall equal 33.05% of the
                  aggregate

<PAGE>   33
                                      -33-


                  diminution in the value of the TelDaFax Group; and (ii) in the
                  event that Purchaser is able to show that the Loss suffered by
                  Purchaser is attributable to other than diminution in the
                  value of the TelDaFax Group then Sellers shall indemnify
                  Purchaser against 100% of such Loss. As long as and to the
                  extent that Sellers are holders of the shares of Consideration
                  Stock received pursuant hereto indemnification within the
                  meaning of this section shall be satisfied by transferring
                  such shares of Consideration Stock back to Purchaser having a
                  value equal to the loss. Thereafter or to the extent Losses
                  are not covered by retransfer of such shares of Consideration
                  Stock Sellers shall indemnify Purchaser by way of a cash
                  payment. For purposes of discharging the indemnification
                  obligation the shares of Consideration Stock shall be deemed
                  to have a value which is equal to the closing quotation on the
                  Nasdaq National Market on the Signing Date.

         12.2     The Purchaser shall only be entitled to assert claims under
                  this ss. 12 if they exceed (together with any claims for
                  indemnification under ss. 13.4) the amount of (e) 1,750,000
                  in the aggregate, but then only for the exceeding amount.

         12.3     All claims under this ss. 12 based on a Breach of Warranty
                  shall be limited in the aggregate to an amount equal to 33% of
                  the Consideration Stock or, in case of indemnification by way
                  of payment in cash, its value as of the Signing Date.

         12.4     The foregoing basket (ss. 12.2) and cap (ss. 12.3) shall not
                  apply to a Breach of Warranty of ss.ss. 11.1, 11.2, 11.3.1.3,
                  11.3.1.4, 11.3.1.5, 11.3.1.7 and 11.5 or in cases where
                  Purchaser is able to show that a Breach of Warranty was known
                  to the Funds at the Signing Date, but not disclosed, provided
                  however that the liability of the Funds can never exceed the
                  value of the Consideration Stock received as of the Signing
                  Date.

         12.5     Any claim of the Purchaser under this ss. 12 is excluded if
                  and to the extent that:

                  12.5.1   the Loss has been compensated to the Purchaser or to
                           the applicable company of the TelDaFax Group, as the
                           case may be, by virtue of an existing

                           insurance policy net of any increase in premiums
                           arising, or likely to arise, out of the payment of
                           such compensation;

                  12.5.2   the damage arising from the Breach of Warranty has
                           been compensated to the Purchaser or to the
                           applicable company of the TelDaFax Group, as the case
                           may be, by a third party other than an insurance
                           company;

                  12.5.3   the circumstances constituting the Breach of Warranty
                           have been known to the Purchaser before the Signing
                           Date by means of the Disclosed Information;

                  12.5.4   the Breach of Warranty is directly and adequately
                           caused by a change after the Closing of the corporate
                           or tax structure or the accounting policies of
                           TelDaFax and its Subsidiaries;

                  12.5.5   the Breach of Warranty is directly and adequately
                           caused by an action or omission (in both cases
                           outside the ordinary course of business) after the
                           Closing of the Purchaser, TelDaFax or its
                           Subsidiaries or any other person whose action or
                           omission is attributable to the Purchaser within the
                           meaning of Section 278 BGB;

                  12.5.6   the Breach of Warranty has the effect of decreasing
                           the tax burden of the Purchaser or TelDaFax or its
                           Subsidiaries, by way of any final tax savings,
                           provided that there are no offsetting tax detriments;

                  12.5.7   reserves contained in the Consolidated 1999 Financial
                           Statements expressly and specifically identified and
                           established for purposes of such Loss - to the extent
                           not reduced or otherwise used prior to the Closing -,
                           which are used or can be used pursuant to U.S. GAAP
                           to offset such Loss provided however that if risk
                           materialises for which such reserves were made, but
                           such reserves were not sufficient to offset the Loss
                           incurred, Purchaser is entitled to claim the
                           exceeding amount as Loss.

         12.6     In case of a claim under ss. 11.3.8 (Tax), the following
                  limitations apply in addition to the provisions of the
                  preceding subsections 12.1 to 12.5:

                  12.6.1   If and to the extent that in a tax audit (Steuerliche
                           Au(beta)enprufung) the profits for tax purposes are
                           increased (for example as a result of non-recognition
                           of deprecations or provisions), but such increase
                           will lead to a decrease of profits for tax purposes
                           in later years (tax accelerations), the amount
                           payable to Purchaser under 12.1 shall be limited to
                           the financing cost of the additional tax liability
                           beginning on the date on which the additional tax
                           liability becomes due pursuant to the relevant tax
                           assessment up to the time when the tax decreasing
                           effects - if applicable on a pro rata basis -
                           realises, whereby the financing cost shall be
                           calculated on the basis of an interest rate of 5%
                           p.a. above the - basic interest rate (Basiszinssatz)
                           relevant for that period of time.

                  12.6.2   If and to the extent that additional corporate income
                           tax is payable by TelDaFax or any of its Subsidiaries
                           and as a result the equity available for distribution
                           which is subject to corporate income tax (mit
                           Korperschaftsteuer belastetes verwendbares
                           Eigenkapital) is increased, such additional taxes are
                           not deemed to constitute a damage to the extent of
                           the corresponding corporate tax credit including the
                           reduction amount (Minderungsbetrag) which is realised
                           at the time of distribution; this restriction shall
                           only apply if and to the extent that the Sold Shares
                           are held by an entity which is entitled to the
                           corporate income tax credit.

         12.7     Notwithstanding the foregoing subsections 12.1 and 12.5 and
                  12.6, the general principles pursuant to ss.ss. 249 seq. and
                  254 BGB regarding the calculation and assessment of
                  reimbursable damages and the duty to mitigate damages remain
                  unaffected.

         12.8     To the extent that representations and warranties are
                  qualified by reference to the best knowledge of the Funds, the
                  knowledge has to be established of the Funds separately.

                  Purchaser, but only severally on a pro rata basis according to
                  the Relevant Percentage of the Consideration in ss. 6.4
                  (Consideration Stock). The cap pursuant to ss. 12.3 shall be

                           asses or to change the relevant tax assessment for
                           the period up to December 31, 1999 ended, however, in
                           any case not prior to the end of the time limits set
                           forth in sub-section 12.10.1 and 12.10.2 with the
                           exception of claims under ss. 11.2.8 resulting from
                           the fact that persons who were treated by TelDaFax
                           at the Signing Date as free agents (Handelsvertreter)
                           have to be treated as employees for tax and/or social
                           security purposes pursuant to binding decisions of
                           competent authorities shall be barred after twelve
                           months from Closing.

                  The statute of limitations shall be interrupted (unterbrochen)
                  or extended (gehemmt) in accordance with the applicable
                  provisions of German law. In case of interruption the new
                  statute of limitations beginning after the end of the
                  interruption (section 217 German Civil Code) shall be 6
                  months; provided, however, that the

                                      -37-


                  period prior and after the interruption in the aggregate shall
                  not be less than eighteen months.

         12.11    Indemnifications by the Funds made according to this ss. 12
                  constitute in the relationship between Funds and Purchaser a
                  reduction of the value of the Consideration Stock and, to the
                  extent they are made directly to a corporation belonging to
                  the TelDaFax Group, in the relationship between Purchaser and
                  the relevant corporation a capital contribution (Einlage).

         12.12    The Funds intend to take out insurance policies providing
                  coverage for such amounts as could be payable by the relevant
                  Fund to Purchaser in respect of any breach and warranties set
                  forth in ss. 11. The Funds herewith assigns any claims under
                  such insurance policies, provided that the mere fact of the
                  assignment of such claims does not affect the obligations of
                  the Funds under this Section 12. The Funds undertake to
                  provide Purchaser with the relevant information and
                  documentation, if they take out the insurance policies and to
                  make all necessary payments thereunder and keep them in full
                  force and effect as long as payment obligations of the Funds
                  to Purchaser subsist. To the extent Purchaser receives
                  payments under the insurance policies, its claims for Breach
                  of Warranties are reduced by such payments. Any limitations on
                  claims of Purchaser as set forth in ss. 12 remain uneffected.


                                   SECTION 13
                           EXCLUSION OF FURTHER CLAIMS

         13.1     The provisions of ss.ss. 11 and 12 of this Agreement represent

                  the consequences of a violation of any representations and
                  warranties of the Sellers.

         13.2     Any further claims of the Purchaser and the Sellers relating
                  to this Agreement and the transactions contemplated herein for
                  a reduction of the Purchase Price, rescission of the
                  Agreement, payment of damages or otherwise, whether on the
                  basis

                  contrahendo), voidability (Anfechtbarkeit) at any other cause
                  of action, shall be excluded.

         13.3     Claims based on deliberate misconduct (vorsatzliches Handeln)
                  are not limited by any of the provisions of this Agreement.

                           11.3.2.5, 11.3.12 and 11.5 being or becoming
                           incorrect;

                  13.4.2   any of the approvals, licences or permits necessary
                           and relevant for TelDaFax to continue the business
                           activities as they existed on the Signing Date being
                           revoked after the Signing Date;

                  13.4.3   TelDaFax entering into a Material Agreement outside

                           practice, or entering into or agreeing to enter into
                           any contracts or arrangements or the type referred to
                           in ss.ss. 11.2.1.9 and 11.2.1.10. without consent of
                           Purchaser after the Signing Date;

                  13.4.4   there having occurred after the Signing Date any
                           event, fact or circumstance that, individually or
                           when considered with any other matter or event, fact
                           or circumstance (including, without limitation, any
                           of the other matters listed in this subsection 13.4),
                           would make or be likely to make a reasonable
                           purchaser, willing to buy the Sold Shares for the
                           consideration and on the terms set out in this
                           Agreement taking into account any diminution in the
                           value of the Consideration Stock from the Signing
                           Date (the "REASONABLE PURCHASER"), to seek a
                           reduction in the value of such consideration in an
                           amount equal to or exceeding 33% of the value of the
                           Consideration Stock as of the Signing Date, provided
                           however that in themselves none of

                           the following events will (in and of themselves) be
                           considered as constituting a material adverse event
                           for these purposes: (i) a fall in the listed stock
                           price of TelDaFax on the Neuer Markt of the Frankfurt
                           Stock Exchange and / or EASDAQ, (ii) a change in the
                           economic situation in Germany or the condition of the
                           financial markets in general (iii) a change in the
                           services and pricing of competitors of TelDaFax to
                           any third party and (iv) changes in applicable laws
                           and/or regulations.

                  13.4.5   failure of Sellers and /or TelDaFax to perform or
                           comply with any of the covenants or agreements
                           contained herein required to be performed, or
                           complied with, at or prior to the Closing, which
                           failure, individually or when considered with any
                           other such failures or any of the other matters
                           listed in this subsection 13.4, would make or be
                           likely to make a Reasonable Purchaser to seek a
                           reduction in the value of such consideration in an
                           amount equal to or exceeding 33% of the Consideration
                           Stock as of the Signing Date; provided, however, that
                           in the event that a matter or matters of the type
                           described in this ss. 13.4.5 (notwithstanding the 33%
                           qualification contained therein) arises or occurs
                           and, due to the fact that such 33% qualification has
                           not been satisfied. Purchaser is not entitled to
                           withdraw from this Agreement pursuant to this ss.
                           13.4, then Sellers and/or TelDaFax as applicable
                           undertake to indemnify Purchaser against such Loss.

         13.5     Subject ss. 13.6 below, the Sellers shall be entitled (without
                  penalty or liability) to withdraw from this Agreement prior to
                  the Closing if any of (but limited to) the following material
                  adverse events should occur after the Signing Date which
                  should be deemed for the purpose of ss. 8.1.4 to also
                  constitute Material Adverse Events:

                  13.5.1   any of the warranties given in ss. 11.4 being or
                           becoming incorrect in any material respects;

                  13.5.2   any of the material approvals, licences or permits
                           necessary and relevant for Purchaser and its
                           affiliates to continue the business activities as
                           they existed on the Signing Date being revoked;

                  13.5.3   there having occurred after the Signing Date any
                           event that, individually or when considered with any
                           other matter or event, would make or be likely to
                           make a reasonable purchaser, willing to buy the
                           Consideration Stock in exchange for the Sold Shares
                           and on the terms set out in this Agreement taking
                           into account any diminution in the value of the Sold
                           Shares from the Signing Date, to seek a reduction in
                           the value of such consideration in an amount equal to
                           or exceeding 33% of the value of the Consideration
                           Stock as of the Signing Date, provided however that
                           in themselves none of the following events will be
                           considered as constituting a material adverse event
                           for these purposes: (i) a fall in the listed stock
                           price of World Access on the Nasdaq National Market,
                           (ii) a change in the economic situation in the United
                           States or the condition of the financial markets in
                           general or (iii) changes in applicable laws and/or
                           regulations.

         13.6     In case of any of the above material adverse events, each
                  party upon becoming aware of the same shall forthwith inform
                  all other parties. The parties undertake to negotiate in good
                  faith for two weeks to amend this Agreement so that it becomes
                  acceptable to both Sellers and Purchaser under the changed
                  circumstances before exercising its right to withdraw. Sellers
                  may only jointly exercise the right to withdraw pursuant to
                  ss. 13.5 by notifying Purchasers accordingly.

                             CONDUCT OF PROCEEDINGS
                                 ACCESS TO FILES

         14.1     Upon making a claim under this Agreement, Purchaser shall use
                  all reasonable endeavours to procure that the Funds are
                  informed, and are kept informed, promptly and fully of all
                  circumstances involving such claim of Purchaser against the
                  Funds hereunder, and shall make available to the Funds copies
                  of all relevant documents. Purchaser shall give the Funds
                  opportunity to take part at their own expense in all relevant
                  meetings and negotiations. As between Purchaser and


<PAGE>   41
                                      -41-


                  the Funds, a settlement (Vergleich), waiver (Verzicht) or
                  acknowledgement (Anerkenntnis) by Purchaser or any corporation
                  belonging to TelDaFax Group shall not contribute evidence for
                  the factual situation or legal position underlying the
                  compromise, waiver or acknowledgement.

         14.2     If and as far as circumstances could give rise to a claim of
                  Purchaser against the Funds hereunder, Purchaser shall use all
                  reasonable endeavours to procure that the Funds are informed
                  of any reports, written opinions given by the tax authorities
                  in connection with the tax audit before the final meeting
                  (Schlu(beta)bericht) and are given the opportunity to take
                  part at their own expense in all meetings with the tax
                  authorities in the context of tax audits and tax assessments
                  relating to period until December 31, 2000, as well as to
                  present their position to the tax authorities in writing. If
                  Purchaser or TelDaFax or any of its Subsidiaries intend to
                  give any written statements to tax authorities referring to
                  periods until December 31, 2000 and relevant for the Funds'
                  position, Purchaser undertakes to inform the Funds in time of
                  such intent so that the Funds can review the intended
                  statements and comment thereon.

                  Upon request and at cost of the Funds, Purchaser shall use all
                  reasonable efforts to procure that all available remedies are
                  used against tax assessments assessing taxes for the period
                  until December 31, 2000, which could result in a claim of
                  Purchaser against the Funds. To the extent remedies cannot be
                  sought in time for reasons of delayed transmission of tax
                  assessments and other documents to the Funds, claims of the
                  Purchaser in respect of the additional tax liability which was
                  to be contested by such remedy shall be excluded. Court
                  proceedings shall be conduced jointly by Purchaser and the
                  Funds, and sentences 1 and 2 of this subsection 14.2 shall
                  apply mutatis mutandis. Purchaser shall use all reasonable
                  efforts to procure that a settlement, waiver or
                  acknowledgement is not entered or not declared into except
                  with the consent of the Funds.

         14.3     Purchaser shall procure that the Funds are granted reasonable
                  access on reasonable notice to all files, documents and
                  information directly relating to tax assessments

                  against the Funds or affiliates of the Funds, or which are
                  otherwise reasonably required by the Funds.

         14.4     It is agreed that the provisions of this ss. 14 shall not
                  apply so as to require the Purchaser to provide any
                  information or documentation or allow the Funds access to any
                  meetings or negotiations where, to do so, would in Purchaser's
                  reasonable opinion be, or might be, unlawful or detrimental to
                  its legitimate commercial interest or those of any affiliated
                  company (including all and any members of the TelDaFax Group).

                                   SECTION 15
                CONDUCT OF THE BUSINESS UNTIL TRANSFER OF SHARES

         15.1.    The Funds, A+M and Klose shall use their best endeavours to
                  procure (including, without limitation, by voting any shares
                  over which they have control) that (i) the business of
                  TelDaFax Group is continued in the ordinary course of business
                  in the period between signing of this Agreement and the
                  Closing and the Purchaser has appropriate access to the
                  management of TelDaFax Group during this period of time, that

                                    Options Shares to the Purchaser. The Sales

                                    forth in the Sales Notice by giving written

                           (b)      If Purchaser does not elect to purchase such
                                    Option Shares, then Klose shall be free to

                  5% in stock of exchange listed corporations shall not
