               of the  Securities  Exchange  Act  of  1934  and  the  rules  and
               regulations  promulgated thereunder) of twenty-five percent (25%)
               or more of the outstanding  voting  securities of the Corporation

               acting as a group,  to acquire  control of the  Corporation.  The
               decision  of the  Committee  as to whether a change in control or

                         consideration   to  be  given   or    received  by  the
                         Corporation  upon  the  exercise  of   any  outstanding
                         Option;

                    (ii) cancel any or all previously granted Options,  provided
                         that   appropriate   consideration   is   paid  to  the

                    (iii)make such  other  adjustments  in  connection  with the
                         Agreement  as the  Committee,  in its sole  discretion,
                         deems necessary, desirable, appropriate or advisable.

     7.   Related Matters.

          (a)  Payment.  Full payment for each Share of Common  Stock  purchased
               upon the  exercise of any Stock  Option  granted  herein shall be
               made at the time of exercise of each such Stock  Option and shall
               be paid in cash (in United  States  Dollars),  Common  Stock or a
               combination  of cash and Common Stock.  Common Stock  utilized in
               full or partial  payment of the exercise price shall be valued at
               its fair market  value at the date of exercise.  The  Corporation
               shall accept full or partial  payment in Common Stock only to the
               extent  permitted  by  applicable  law. No Shares of Common Stock
               shall be issued until full payment therefore has been received by
               the Corporation,  and no Participant shall have any of the rights
               of a stockholder of the  Corporation  until Share of Common Stock
               are issued to him.

          (b)  Cashless Exercise.  A Participant who has held a Stock Option for
               at least six months may engage in the "cashless  exercise" of the
               Option.  In  a  cashless   exercise,   a  Participant  gives  the
               Corporation written notice of the exercise of the Option together
               with an order to a registered  broker-dealer  or equivalent third
               party,  to sell part or all of the Optioned  Stock and to deliver
               enough of the proceeds to the Corporation to pay the Option price
               and any applicable withholding taxes. If the Participant does not
               sell the Optioned  Stock  through a registered  broker-dealer  or
               equivalent  third  party,  he can  give the  Corporation  written
               notice  of the  exercise  of  the  Option  and  the  third  party
               purchaser of the  Optioned  Stock shall pay the Option price plus
               any applicable withholding taxes to the Corporation.

          (c)  Transferability.   Any  Stock  Option  granted  pursuant  to  the
               Agreement shall be exercised during a Participant's lifetime only
               by the  Participant  to  whom it was  granted  and  shall  not be
               assignable or transferable  otherwise than by will or by the laws
               of descent and distribution.

          (d)  Effect  of  Termination  of  Employment  or  Service.   Upon  the
               termination  of a  Participant's  employment  or service with the
               Corporation  or the  Bank as a  Director,  Director  Emeritus  or
               Employee,  the  Participant may continue to exercise such Options
               for a  period  of six  months  from the  date of  termination  of
               employment or service by the Participant,  but not later than the
               date on which the Option would otherwise expire.  Such Options of
               a deceased Participant may be exercised within two years from the
               date of his or her  death,  but not later  than the date on which
               the Option would otherwise expire.

          (e)  Change in Applicable  Law.  Notwithstanding  any other  provision
               contained  in the  Agreement,  in the  event of a  change  in any
               federal or state law,  rule or  regulation  which  would make the
               exercise of all or part of any  previously  granted  Stock Option
               unlawful or subject the Corporation to any penalty, the Committee
               may  restrict  any  such  exercise  without  the  consent  of the
               Participant  or other holder  thereof in order to comply with any
               such law, rule or regulation or to avoid any such penalty.

          (f)  Conditions  Upon  Issuance of Shares.  Shares shall not be issued
               with respect to any Option granted under the Agreement unless the
               issuance  and  delivery  of such  Shares  shall  comply  with all
               relevant provision of law,  including,  without  limitation,  the
               Securities  Act of 1933,  as amended,  the rules and  regulations
               promulgated  thereunder,  any applicable state securities law and
               the  requirements of any stock exchange upon which the Shares may
               then be listed.

The inability of the Corporation to obtain from any regulatory body or authority
deemed by the  Corporation's  counsel to be necessary to the lawful issuance and
sale of any Shares  hereunder  shall relieve the Corporation of any liability in
respect of the non-issuance or sale of such Shares.

As a condition to the  exercise of an Option,  the  Corporation  may require the
person exercising the Option to make such  representations and warranties as may
be necessary to assure the  availability  of an exemption from the  registration
requirements of federal or state securities law.

          (g)  Withholding  Tax. The Corporation  shall have the right to deduct
               from  all  amounts  paid in cash  with  respect  to the  cashless
               exercise of Options under the Agreement any taxes required by law
               to be  withheld  with  respect  to such  cash  payments.  Where a
               Participant  or  other  person  is  entitled  to  receive  Shares
               pursuant to the Exercise of an Option  pursuant to the Agreement,
               the  Corporation  shall have the right to require the Participant
               or such  other  person to pay the  Corporation  the amount of any
               taxes which the  Corporation is required to withhold with respect
               to such  Shares,  or,  in lieu  thereof,  to  retain,  or to sell
               without notice,  a number of such Shares  sufficient to cover the
               amount required to be withheld.

          (h)  Governing  Law. The Agreement  shall be governed by and construed
               in accordance with the laws of the State of Kansas, except to the
               extent that federal law shall be deemed to apply.

          (i)  Administration. All decisions,  determinations and interpretation
               of the  Committee  shall be final and  conclusive  on all persons
               affected thereby.

          severable  and the  invalidity  or  unenforceability  of any provision

          modifications  thereof as agreed to in writing by the  parties,  shall

TEK Undertakings

1.   TEK will provide the TEK iGate product, as well as necessary technical
     support, to ePhone as a hardware vendor. The existing two port V-Server
     will be productized to facilitate the launch of the ePhone service by
     August 2, 1999.

2.   The initial launch of the service will be based on the existing 2 port unit
     with minor modifications (modifications to be specified and agreed). This
     will also form the basis of a mutually agreed upon acceptance plan (Gateway
     with Billing Capability).

3.   TEK agrees to ensure that the product passes CE for LAN (ie. non-ISDN &
     Class A) by July 30, 1999. ePhone acknowledges that in order to obtain CE
     Class A certification for ISDN by September 15, 1999 additional equipment,
     estimated to cost $50,000 (specifications and details to be supplied by
     TEK), will be required. ePhone further acknowledges that this additional
     equipment must be ordered by August 1, 1999 by TEK in order to meet the
     September 15, 1999 date. There will be penalty to TEK if it does not meet
     the CE certification for ISDN by September 15, 1999. This penalty will be
     calculated on the basis of the costs incurred by ePhone due to the missing
     of the September 15th deadline, plus 50%.

4.   For all units additional to the initial order of 500 units, TEK agrees to
     provide ePhone with all new units at a maximum price of cost plus a maximum
     markup of 30% for 3 years. Cost is defined to include all licensing,
     royalties, manufacturing, and 3rd party warranty support costs. ePhone will
     have the right to audit these costs. The first 500 units are priced at
     $700, as previously agreed, but additional units will be priced in
     accordance with a volume discount schedule supplied by TEK (Addendum B to
     this agreement). For the same volume of iGates TEK will offer ePhone a
     preferred volume discount schedule as compared to other purchasers of
     iGates.

5.   TEK agrees that the optional features of the TEK iGate product line will be
     compatible with ePhone's service and will provide preferential access to
     ePhone and further that TEK will provide access server directory records
     including billing capability (tested and approved by ePhone) so that ePhone
     can maintain a WEB based directory. This optional feature will be based on
     cost-plus program for TEK to design and implement per ePhone's requirement.

                                      -2-

6.   TEK will guarantee the best markup rate within same category to ePhone
     comparing to all distributors & OEM accounts. The same products cannot be
     sold by TEK to undercut pricing offered to ePhone and TEK cannot deal with
     or sell to ePhone's distributors. TEK will bundle ePhone services to all
     customers who need services and will not act as a carrier itself.

7.   TEK agrees that Gateway solutions & Network Design developed and brought in
     by ePhone shall be treated as confidential and proprietary information and
     shall not be provided or disclosed to any other parties without prior
     approval of ePhone. The same solution cannot be sold without going through
     ePhone's worldwide channels.

8.   TEK agrees to assist ePhone in developing exclusive territorial sales
     territories in China, Vietnam and Taiwan, and other countries as may be
     mutually agreed. In cases where TEK has authorized other sellers of TEK
     iGates TEK will facilitate introductions of ePhone to those sellers, so
     that ePhone will be able to coordinate sales efforts. The negotiations with
     these other sellers and the development of those sales territories will be
     ePhone's responsibilities.

                  Europe, Mid-East and Africa, subject to the undertakings
                  agreed to by ePHONE as described in Section B. These rights
                  are to be non-cancelable by TEK for two years (provided ePHONE
                  fulfills its obligations under this agreement) and subject to
                  annual renewal under mutually agreed terms thereafter.

         3.       The "Exclusive ITSP Rights" are defined as: TEK will not sell
                  any products (with TEK's brand name and/or through any other
                  OEM brand names) to any "Telephony- Related Businesses" which
                  might be in direct/indirect competition with ePHONE's and/or
                  its partners' ITSP businesses in those regions defined in item
                  A.2 of TEK's Undertakings. In cases where TEK identifies new
                  business opportunities in the exclusive regions TEK will have
                  the right to bring these to ePHONE for mutual negotiation.

                  categories (including OEM) of customers that TEK shall not
                  offer lower selling pricing to its customers to compete with
                  ePHONE's customers. TEK agrees to ePHONE that a quarterly
                  audit can be performed anytime to verify the effects of price

                  hardware".

         7.       In order to achieve prompt deployment in the exclusive ITSP
                  territories described in A.2, TEK grants to ePHONE the option
                  to manufacture vSERVER/iGATE itself or assign the

                  protection.

                  sub-contractor) ePHONE agrees to provide TEK with a P.O. with
                  a 10% non-refundable deposit. Pricing is to be as per the MOU
                  or on more favorable terms in case of higher volumes that

         3.       If ePHONE manufactures the products described in B.1 or
                  assigns these manufacturing rights then ePHONE agrees to pay a
                  one time "manufacturing rights fee" and per unit "product
                  royalties" to TEK. These are described in B.4 and B.5
                  respectively. TEK will supply manufacturing support to
                  ePHONE's designated manufacturer in return for "booking" the
                  transaction at no extra cost to ePHONE or the manufacturer,

                           agreement or the date of ePHONE's signing of an
                           agreement with a third party for these rights,
                           whichever comes first - subject to completion and
                           verification of the "ePHONE Solution" as per the
                           Request for Proposal.

                           $250,000 payable within 45 days of the first payment

                           $100,000 payable every 30 days, commencing 30 days
                           after the date of the second payment, until a total
                           of $1,500,000 has been paid

         5.       The "product royalties" will be a payment of $160 per unit,
                  payable when the unit is shipped from the manufacturer. This
                  royalty will include all other royalties payable by TEK to
                  third parties. This royalty will be in accordance with item
                  A.4 and will be adjusted if ePHONE does not have the most
                  favorite OEM pricing and/or licensing fees.
