1.       BUSINESS

         Voice Control Systems, Inc. (the "Company" or "VCS") engages in the
design of voice recognition systems that allow for the voice control of
electronic machines and/or devices. Operating results for the six months ending
June 30, 1997 are not necessarily indicative of the expected results for the
year. The unaudited financial statements include all adjustments, consisting
primarily of normal recurring accruals, which management considers necessary
for a fair presentation of such information.



2.       BUSINESS ACQUISITION

         The Company and Voice Processing Corporation ("VPC") entered into an
Agreement and Plan of Merger, approved on October 29, 1996 by each Company's
stockholders of record, pursuant to which VPC was merged into the Company.
Effective November 4, 1996, all of VPC's common stock was converted into and
exchanged for 0.87091 shares of VCS common stock in a transaction accounted for
using the pooling-of-interest method of accounting. In addition, all options
and warrants to purchase VPC shares were exchanged for options and warrants to
purchase VCS shares at the 0.87091 exchange rate. The stock conversion referred
to above has been retroactively reflected in the financial statements for all
periods presented.

         Separate results of operation for the periods prior to the merger with
VPC are provided below.

3.       PER SHARE INFORMATION

         Earnings per common and common equivalent share are computed based
upon the weighted average number of outstanding shares of common stock and
common stock equivalents.

4.       STOCK OFFERING

         On February 14, 1996, the Company completed the sale of 1,269,402
shares of common stock. In March 1996, the underwriters exercised their
overallotment option for an additional 220,500 shares of common stock. Net
proceeds to the Company from the stock offering and from stock options
excerised in conjunction with the offering totaled $14,432,000.

5.       ACCOUNTS PAYABLE AND ACCRUED EXPENSES

         Accounts payable and accrued expenses consist of the following at June
30, 1997:

6.       INCOME TAXES

           The combined net operating loss (NOL) carryforwards of the merged
Company expire from 1997 to 2011 and total approximately $23,698,000 as of June
30, 1997. The Company has provided an allowance against its entire deferred tax
asset relating primarily to NOL carryforwards of approximately $8,114,000. In
connection with the Industries acquisition, effective as of August 11, 1994,
the Company had an ownership change as defined by Internal Revenue Code Section
382 (IRC 382). The effect of such change limited the use of the Company's NOL
in future years to approximately $1,355,000 annually. In connection with the
merger with VPC, VPC had an ownership change as defined by IRC 382. The effect
of such change limits the use of VPC's NOL in future years to approximately
$850,000 annually. On a combined basis, the NOL of the Company is limited in
its use against future earnings, if any, to approximately $2,205,000 Annually.

         The Company has provided an allowance for its entire deferred tax
asset as its realization is dependent upon future generation of taxable income,
which is not assured. Until such realization can be reasonably determined based
on established sources of earnings sufficient to utilize the NOL carryforward,
management will continue to provide an allowance for the entire deferred tax
asset.

7.       MAJOR CUSTOMERS

         Two customers accounted for 32% and 14% of total sales revenue for the
six months ended June 30, 1997. Three customers accounted for 25%, 10% and 10%
of total sales revenue for the six months ended June 30, 1996.

         The Company's largest customer was also the holder of its short-term
convertible debt. The promissory note and accrued interest was converted to
1,300,694 shares of common stock on January 1, 1997. Accounts receivable from
the two largest customers were 9% and 16% of the total receivable balance at
June 30, 1997.

8.       NEW ACCOUNTING PRONOUNCEMENT

         On March 3, 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share". This statement simplifies the standards for computing and presenting
earnings per share ("EPS") and makes them comparable to international EPS
standards. SFAS 128 replaces the presentation of primary EPS with a
presentation of basic EPS. It also requires dual presentation of basic and
diluted EPS on the face of the income statement for all entities with complex
capital structures. While early adoption is not permitted, disclosure of the
effect of the adoption of the standard is required. If SFAS 128 was applied to
the six-month periods ended June 30, 1997 and 1996, the earnings per share
would be as follows:

PART I - FINANCIAL INFORMATION

ITEM 2.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
              FINANCIAL CONDITION

RESULTS OF OPERATIONS

Six months Ended June 30, 1997 vs. June 30, 1996

Sales increased 22% from $6,787,000 during the six months ending June 30, 1996
to $8,265,000 during the six months ending June 30, 1997. Two customers,
Dialogic and Glenayre, accounted for 32% and 14%, respectively, of total sales
for the six months ending June 30, 1997. Dialogic, Brite and Periphonics
accounted for 25%, 10% and 10%, respectively, of total sales for the six months
ending June 30, 1996. Royalty, development and license fees, which increased
49% over the six months ending June 30, 1996, were 30% of total revenues for
the six months ending June 30, 1997. Hardware sales, which increased 16% over
the six months ending June 30, 1996, were 64% of revenues in the six months
ending June 30, 1997. This increase in hardware sales is a result of the
company's contract with OKI Telecom.

Cost of sales includes the cost of components and subcontracted manufacturing
related to hardware products. Gross profit as a percent of sales was flat at
79% in the six months ending June 30, 1996 and 1997 as a result of the product
mix sold.

Research and development expenses decreased 21% from $3,297,000 in the six
months ending June 30, 1996 to $2,595,000 in the six months ending June 30,
1997. This decrease reflects cost reductions as a result of the merger with
VPC.

Selling, general, and administrative expenses increased 12% from $3,131,000 in
the six months ending June 30, 1996 to $3,493,000 in the six months ending June
30, 1997. Additional sales persons have been added to help support a growing
customer base of firms utilizing speech recognition technology.

The combined net operating loss ("NOL") carryforwards of the merged Company
expire from 1997 to 2011 and total approximately $23,698,000 as of June 30,
1997. The Company has provided an allowance against its entire deferred tax
asset relating primarily to NOL carryforwards of approximately $8,114,000.
Effective August 11, 1994, the Company had an ownership change as defined by the
Internal Revenue Code Section 382 (IRC 382). The effect of the change limited
the use of the Company's NOL in future years to approximately $1,355,000
annually. In connection with the merger with VPC, VPC had an ownership change as
defined by IRC 382. The effect of such change limits the use of VPC's NOL in
future years to $850,000 annually. On a combined basis, the NOL of the Company
is limited in its use against future earnings, if any, to approximately
$2,205,000 annually. Federal income taxes and state franchise taxes based on
income have been offset by net operating loss carryforwards thus far in 1997.
The Company has incurred a tax based on the federal alternative minimum tax of
$10,750 for the six months ended June 30, 1997.

Three months Ended June 30, 1997 vs. June 30, 1996

Sales increased 38% from $3,088,000 during the three months ending June 30,
1996 to $4,262,000 during the three months ending June 30, 1997. Three
customers, Dialogic, Glenayre, and OKI Telecom, accounted for 29% and 18%, and
13% respectively, of total sales for the three months ending June 30, 1997.
Dialogic, Brite and Periphonics accounted for 19%, 16% and 10%, respectively,
of total sales for the three months ending June 30, 1996. Royalty, development
and license fees, which increased 24% over the three months ending June 30,
1996, were 24% of total revenues for the three months ending June 30, 1997.
Hardware sales, which increased 55% over the three months ending June 30, 1996,
were 70% of revenues in the three months ending June 30, 1997. This increase in
hardware sales is a result of the company's contract with OKI Telecom.

Cost of sales includes the cost of components and subcontracted manufacturing
related to hardware products. Gross profit as a percent of sales decreased from
83% in the three months ending June 30, 1996 to 75% in the comparable 1997
period as a result of the increase in hardware sales for the period.

Research and development expenses decreased 21% from $1,693,000 in the three
months ending June 30, 1996 to $1,337,000 in the three months ending June 30,
1997. This decrease reflects cost reductions as a result of the merger with
VPC.

Selling, general, and administrative expenses increased 6% from $1,601,000 in
the three months ending June 30, 1996 to $1,703,000 in the three months ending
June 30, 1997. Additional sales persons have been added to help support a
growing customer base of firms utilizing speech recognition technology.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal cash requirements to date have been to fund working
capital and capital expenditures in order to support its sales growth. Net
working capital at June 30, 1997 was $16,743,000. In the past, the Company's
working capital needs were financed primarily through cash flow from operations
and proceeds from the exercise of warrants and stock options. A stock offering
was completed during the first quarter of 1996 that provided net proceeds of
$13,446,000 to the Company.

At June 30, 1997, the Company held $14,343,000 in cash and cash equivalents.
Cash and cash equivalents are invested in institutional cash investment
accounts with preservation of capital being the primary consideration. All
investments currently have overnight liquidity. Historically, the Company's
primary source of liquidity has been the timely collection of its accounts
receivable. The average day's sales in accounts receivable was 86 days as of
June 30, 1997.

The Company's  inventory as of June 30, 1997 was $530,000 of which non-telecom
products were  approximately  58% of the inventory.


                                      10
<PAGE>   11

The Company maintained no debt obligations as of June 30, 1997.

The Company's capital expenditures were $195,000 for the six months ended June
30, 1997. The expenditures were primarily for computer equipment.

VCS believes that its existing sources of liquidity, funds generated by
operations and the funds received from the stock offering will be sufficient to
provide the capital resources necessary to support increased operating needs
and finance continued growth in the foreseeable future.

                             DISTRIBUTION AGREEMENT


         This Distribution Agreement is made this 23rd day of June, 1997 by and
between Dialogic Corporation, a New Jersey corporation, with headquarters at
1515 Route 10, Parsippany, New Jersey 07054 ("Dialogic"), and Voice Control
Systems, Inc., a Delaware corporation, with headquarters at 14140 Midway Road,
Suite 100, Dallas, Texas 75244 ("VCS").

                             BACKGROUND INFORMATION

         Dialogic is a manufacturer of voice processing components. One of
Dialogic's products lines is based on its SCSA architecture; the speech
recognition platform that is available in the SCSA architecture is known as
Antares. VCS has developed speech recognition technology that is available with
a variety of capabilities. Dialogic has licensed certain speech recognition
capabilities from VCS under a License Agreement dated June 8, 1990, that has
subsequently been amended several times. VCS provides support to Dialogic for
the Basic Technology it has licensed under a Support Agreement dated September
20, 1991, as subsequently amended. In addition to the Basic Technology that
Dialogic has licensed, VCS has certain Enhanced Technologies available that
provide capabilities such as High-Density Continuous, Speaker-Dependent,
Speaker Verification, PowerBundle, Discrete Word Spotting, and Alphanumeric.
VCS continues to develop new Enhanced Technologies such as Password
Verification. Dialogic currently sells Antares products with VCS' Basic
Technology, and Dialogic wishes to offer Enhanced Technologies to its customers
who are then purchasing or have already purchased Antares products with Basic
Technology ("Customers"). VCS is willing to permit Dialogic to do so on the
terms and conditions of this Agreement.

Accordingly, in consideration of the above and the mutual agreements below, and
using certain terms herein in accordance with the definitions attributed to
them in Addendum I attached hereto and incorporated herein by reference,
Dialogic and VCS agree as follows:

                             SUBSTANTIVE PROVISIONS

1.       Appointment. VCS hereby appoints Dialogic as its non-exclusive 
distributor of licenses for Enhanced Technologies for use on Dialogic's Antares
products and Dialogic accepts the appointment. Dialogic will offer and actively
promote VCS' Enhanced Technologies to Antares Customers. In order to induce
Antares Customers to order VCS' Enhanced Technologies, Dialogic agrees to
credit * ports towards a Customer's VPA contract for each port of VCS' Enhanced
Technologies that the Customer licenses from Dialogic.

2.       Configuration. Dialogic will offer Enhanced Technologies in fixed board
configurations based on the maximum DSP loads of each technology. The
preliminary list of configurations is set forth in Exhibit B attached hereto
and incorporated herein by reference; Dialogic has developed or will develop
Dongles and VCS will develop software packages of the Enhanced Technologies in
these 


* Confidential treatment requested.

<PAGE>   2

configurations in each operating system that the companies mutually agree
provide the best business opportunity. Each software package will include the
appropriate Enhanced Technologies, release notes, a license, an instruction
letter in the form of Exhibit A attached hereto and incorporated herein by
reference and any other software required to run the Enhanced Technologies on
the Antares platform. The package will be sealed with appropriate instructions
regarding the order in which to open envelopes within the package. The
configuration list will be expandable, and VCS and Dialogic agree to work
together to determine the appropriate number and configuration of product
offerings. As configurations are added to the list by mutual agreement of the
parties (which shall be evidenced by initializing amendments to Exhibit A),
Dialogic will develop Dongles for them. Additions to the configuration list
require at least two to three weeks lead time. If a Customer has an immediate
need for a non-standard configuration, Dialogic will provide non-production
Dongles and VCS will provide an appropriate software package software for
Enhanced Technologies the Customer has ordered for shipment to the Customer.
The configuration represented in the non-production Dongles will be added to
the configuration list after shipment, and Dialogic will develop a production
Dongle for that configuration. The Customer who received a non-production
Dongle will be required to exchange it for the production Dongle when it is
available.

         2.1 Enhanced API Features In Basic Packages. VCS desires to maintain a
single code base and include its Enhanced Technology API functions in the Basic
Technology software packages tested and shipped by Dialogic, but Dialogic is
concerned that problems encountered with these elements of the Enhanced
Technology API functions could cause Dialogic to re-test and re-release Basic
Technology software packages that would have otherwise have required no action.
Therefore, the parties will limit the number of Basic Technology software
package re-tests and re-releases to one per quarter per operating system, which
may be exceeded if both parties agree it is in their mutual best interest or if
a problem is encountered in elements of the Basic Technology software package.

3.       Order Fulfillment and Payment. Dialogic will purchase software 
packages for each configuration from VCS at a price of * per package. Upon
accepting a purchase order for VCS Enhanced Technologies, Dialogic will deliver
the Dongle and software package that the Customer requires to implement the
Enhanced Technologies he has ordered. Dialogic will bill the Customer for the
Enhanced Technologies and collect its charges. Dialogic shall pay VCS for each
Enhanced Technology software package sold according to the price schedule shown
in Exhibit C attached hereto and incorporated herein by reference. Payments
will be due quarterly by the 15th day of April, July, October, and January for
Enhanced Technologies software packages sold during the preceding calendar
quarter, as evidenced by either shipment of the software package or invoicing.
Dialogic will also provide Enhanced Technologies sales reports on a monthly
basis, by including Enhanced Technology sales information in the reports
currently prepared and delivered for Basic Technology sales. Each monthly
report will furnish VCS the name of each customer who purchased an Enhanced
Technology during the month, its VPA level, a summary of the Dongles and
software packages purchased, and any other information reasonably requested by
VCS. With respect to any amount owed to VCS that is not paid by the due date,
VCS shall have the right to require that Dialogic pay VCS interest from the due
date to date of payment at the rate of one and one-half (1-1/2%) percent per
month on the unpaid balance (or such lower rate as may be the 


* Confidential treatment requested.


<PAGE>   3

maximum allowable by law), together with VCS' costs of collection (including
reasonable attorney's fees).

         3.1 Upgrades. Customers using existing Basic Technologies and wishing
to upgrade to an Enhanced Technology product will be required to order and
license the appropriate Enhanced Technology Dongle and software package. Upon
receiving the Enhanced Technology Dongle, the Customer will return the Basic
Technology Dongle to Dialogic and receive full credit for the Basic Technology
license. No other credits will be allowed for open packages of software.

4.       Audit Rights. Dialogic hereby grants to VCS' duly accredited 
representative, who shall be a certified public accountant, the right to
periodically inspect and make copies of Dialogic's books of accounts and
records pertaining to shipment of Dongles and Enhanced Technologies during
ordinary business hours, only for the purpose of (a) verifying payments made
under this Agreement, and/or (b) to obtain information as to payments due and
payable. Such inspections shall be made no more often than annually and only
upon five days prior written notice to Dialogic. The cost of such inspection
will be borne by VCS, except if upon examination it is agreed that VCS has been
underpaid by 5% or more by Dialogic, then such payment and all reasonable costs
associated with the examination shall be paid by Dialogic within ten (10) days
following such agreement.

5.       Modification. VCS may modify the vocabulary or other elements of the
Enhanced Technologies software, including, without limitation, modifying a
PowerBundle by adding words to the basic vocabulary to meet a Customer's
requirements, but VCS will not add ports, modify the configuration or change
the basic functionality. 

6.       Warranty. VCS warrants that the diskette on which Enhanced 
Technologies are furnished to the Customer shall be free from defects in
materials and workmanship under normal use for a period of 90 days from the
date of delivery to the Customer. If such a defect appears within the warranty
period, the Customer may return the defective diskette to VCS for replacement
without charge. Replacement is the Customer's sole remedy with respect to such
a defect.

7.       Support. Dialogic will provide support for Customers for problems 
incurred during downloading and running the Antares demonstration program
(a.k.a. Rec-Play demo). Customers purchasing Enhanced Technologies will be
automatically shipped the Basic Technology package by Dialogic in addition to
the Enhanced Technology software. Customers will be instructed to install,
configure and run the Basic Technology demonstration programs first. Customers
will be instructed to contact Dialogic directly if any problems are encountered
to this point. If the Basic Technology has been installed and run to the
Customer's satisfaction, they will then be instructed to install and configure
the Enhanced Technology software. From this point forward, all support calls
will be directed to VCS. Customers using a mixture of Basic and Enhanced
Technologies in the same system will receive all support for both Basic and
Enhanced technologies directly from VCS after initial basic installation as
described here.

8.       Additional VCS Charges. VCS may charge Customers who acquire Enhanced
Technologies engineering fees and support fees for services rendered to them.
VCS will provide the appropriate Dialogic Account Manager with the details of
such arrangement including the 


* Confidential treatment requested.


<PAGE>   4

anticipated charges. Such charges will be negotiated by VCS and paid directly
by the Customer to VCS.

9.       Term. This Agreement shall become effective on the date hereof and 
unless sooner terminated extend for a period of one year; this Agreement will
be renewed from year to year thereafter unless terminated by either party by
giving written notice of non-renewal at least 30 days prior to the end of the
then-current term.

10.      Termination.  This Agreement may be terminated as follows:

         10.1 If either party fails to fulfill any material obligations or
conditions hereof, or commits any other breach or is in default in any other
way with regard to any of the provisions of this Agreement, and such failure,
breach, or default is not cured within thirty (30) days of written notice to
the defaulting party by the other party specifying the nature of the default,
the aggrieved party will have the right to terminate this Agreement by giving
written notice of termination to the defaulting party, whereupon this Agreement
shall automatically terminate on the 30th day after such termination notice is
given. Either party will have the right to cure any such default up to but not
after receiving notice of termination.

         10.2 In the event that under the laws of the United States either
party files for bankruptcy or is deemed insolvent or is obliged to cease to
trade or to wind-up its affairs and go into liquidation, or should it seek
protection from its creditors or a rearrangement of its obligations by legal
process, or otherwise, or a committee of creditors be appointed, or any similar
proceedings be had or commenced pursuant to the laws of any jurisdiction or
otherwise, the other party shall be entitled to give written notice terminating
this Agreement forthwith without prejudice to any rights of either Licensee or
VCS which may have accrued hereunder at or as of the date of such termination.

         10.3 If Dialogic's annual payments to VCS under all agreements between
them, including, without limitation, this Agreement, any license agreement or
any support agreement do not exceed * in any calendar year, VCS shall have the
right to terminate this Agreement by giving written notice to Dialogic.

         Termination of this Agreement for any cause shall not be construed as
a waiver in respect of either party of any of its rights, claims (including
claims for damages) or obligations that have accrued up to and including the
date of termination, including Dialogic's obligation to pay any sums accrued to
VCS.

11.      Patent Warranty and Indemnity. VCS represents and warrants that it 
has the right to grant licenses to Customers regarding use of its Enhanced
Technologies. VCS and Dialogic will cooperate to assure that all requisite
patent, trademark and copyright notices are provided. VCS shall indemnify and
hold Dialogic and Customers harmless against any and all costs, claims,
damages, expenses, losses and demands (including legal expenses) incurred by or
against Dialogic or a Customer as a result of or in connection with any claim
made or alleged that an Enhanced Technology infringes any United States or
European Union patent, copyright, trade secret, trademark or other intellectual
property rights of any third party, conditioned on the following:


* Confidential treatment requested.


<PAGE>   5

         (A) That VCS shall be notified promptly in writing by Dialogic of any 
         notice of such claims; and

         (B) That VCS shall have the sole control of the defense of any action
         on such claim and all negotiations for its settlement or compromise.

         Should an Enhanced Technology be held, or in VCS' opinion be likely to
be held, to infringe such intellectual property rights, VCS shall, at its
expense, (i) procure for Customers the right to continue using the Enhanced
Technology, (ii) replace or modify the same so that it becomes noninfringing
but still performs substantially the same functions that the Enhanced
Technology performed prior to replacement or modification, or (iii) withdraw
the Enhanced Technology and refund to Customer the amortized charge for the
Enhanced Technology paid to VCS by Dialogic as herein provided, as amortized
ratably over sixty months.

         Notwithstanding the foregoing, VCS shall have no liability to Dialogic
or its Customers with respect to any claim of patent infringement which is
based upon a claim that an application in which an Enhanced Technology is used
violates the intellectual property rights of another person or entity.

12.      Training.  VCS will provide training to Dialogic's sales force to 
assist in selling Enhanced Technologies.

13.      Exclusivity. VCS will generally refer Antares Customers desiring 
Enhanced Technologies to Dialogic and endeavor to persuade Antares Customers to
order Enhanced Technologies from Dialogic; however, this Agreement is
non-exclusive and VCS is permitted to market its Enhanced Technologies to
Antares Customers where business reasons indicate such action is appropriate.

14.      Headings.  Headings used in this Agreement are to facilitate reference
only, do not form a part of this Agreement, and shall not in any way affect the
interpretation hereof.

15.      Assignability. This Agreement, and all rights and obligations 
hereunder, are personal as to the parties hereto and may not be assigned, in
whole or in apart, by any of the parties to any other person, firm or
corporation without the prior written consent thereto by the other party
hereto, which consent shall not be unreasonably withheld; except that either
party may freely assign any or all of its rights and obligations hereunder to
any Affiliate. An Affiliate assignee will thereupon be free to assign the
rights and obligations under this Agreement to any other Affiliate. Any
assignment contrary to the terms hereof shall be null and void and of no force
or effect.

16.      No Waiver.  No failure on the part of any party to exercise, and no 
delay in exercising, any right or remedy hereunder shall operate as a waiver
thereof. Nor shall any single or partial exercise of any right or remedy
hereunder exclude any other or further exercise thereof or the exercise of any
other right hereunder.

17.      Entire Agreement. This Agreement and all schedules and exhibits 
annexed hereto constitute the entire agreement among the parties respecting the
subject matter hereof and supersedes all prior 


* Confidential treatment requested.

<PAGE>   6

agreements among the parties relative to the subject matter hereof. In entering
this Agreement, Dialogic did not rely on any representations or warranties of
VCS or its employees or agents other than those set forth in this Agreement.
This Agreement may not be modified or amended except by a writing that states
that it is an amendment to this Agreement and that is signed by duly authorized
representative of the parties. In the event of any conflict between the terms
of this Agreement and any purchase orders, acknowledgments, submissions,
correspondence, memoranda, listing sheets or any other documents, the terms of
this Agreement, as amended from time to time, will govern and prevail.

18.      Notices. All notices required or permitted to be given hereunder shall 
be in writing and will be valid and sufficient if dispatched either (i) by hand
delivery, (ii) by telex, cable or facsimile transceiver, with confirming letter
mailed promptly thereafter in accordance with clause (iv) hereof, (iii) by
reputable overnight express courier or (iv) by certified mail, postage prepaid,
return receipt requested, deposited in any post office in the United States, in
any case, addressed to the addresses set forth on the first page of this
Agreement, or such other addresses as may be provided from time to time in the
manner set forth above. When sent by cable or facsimile as aforesaid, notices
given as herein provided will be considered to have been received when sent
during normal business hours; otherwise, notices will be considered to have
been received only upon delivery or attempted delivery during normal business
hours.

19.      Partial Invalidity. If any clause or provision of this Agreement is 
held to be illegal, invalid, or unenforceable under present or future laws
effective during the term of this Agreement, then and in that event, it is the
intention of the parties hereto that the remainder of this Agreement shall not
be affected thereby, and it is also the intention of the parties to this
Agreement that in lieu of each clause or provision of this Agreement that is
held to be illegal, invalid, or unenforceable, there be added as a part of this
Agreement a clause or provision as similar in terms to such illegal, invalid,
or unenforceable clause or provision as may be possible and still be legal,
valid, and enforceable.

20.      Costs and Attorneys' Fees. The prevailing  party in any litigation,  
arbitration or other proceedings arising out of this Agreement shall be
reimbursed by the other party for all costs and expenses incurred in such
proceedings, including reasonable attorneys' fees.

21.      Force Majeure. No party hereto shall be liable for delay or default in
performing hereunder, other than a delay or default in payment of any monies
due to the other party, if such performance is delayed or prevented by a Force
Majeure Condition. If a Force Majeure Condition occurs, the party delayed or
unable to perform shall give prompt notice of such occurrence to the other
party. The party affected by the other party's inability to perform may, after
sixty (60) days, elect to either terminate this Agreement or continue
performance with the option of extending the terms of the Agreement up to the
length of time the Force Majeure Condition endures. The party experiencing the
Force Majeure Condition must inform the other party in writing when such a
condition ceases to exist.

22.      Confidentiality. Each party covenants and agrees that at all times
hereafter it will keep secret all information communicated to it which has been
designated as confidential or proprietary, and that it will not divulge the
same to any person, firm, or corporation or use it for its benefit or for


* Confidential treatment requested.

the benefit of others without the prior written consent of the other party.
This obligation shall apply only if in the case of written communication, the
document has been conspicuously labeled as "confidential" or "proprietary" and
in the event of an oral communication, the information has been identified as
confidential or proprietary at the time of disclosure and a written summary of
the confidential or proprietary information, conspicuously marked as such, has
been prepared by the disclosing party and sent to the receiving party within 30
days of the disclosure. The recipient shall take reasonable steps to safeguard
such confidential information, using at a minimum the same degree of care that
the recipient uses to protect its own similar categories of confidential and
proprietary information. The provisions of this Article shall not apply to:

         (A) Information that at the time of receipt can be shown by reasonable
         evidence  to be in the  public domain;

         (B) Information that can be shown by reasonable evidence to have been
         legally in possession of the party receiving such information prior to
         the time of it being received from the other party; or

         (C) Information that can be shown by reasonable evidence to have
         legally become part of the public domain, other than by acts or
         omissions of the party receiving such information.

         For the purpose of sub-paragraphs (A) and (C) of this section,
information shall not be considered to be in the public domain merely because a
more generalized disclosure of information, which does not specify the details
of the information received, is in the public domain.

         If any party is required to disclose information to a third party
pursuant to a lawfully issued subpoena or other formal demand for the
production of information by a court of competent jurisdiction or a regulatory
body with jurisdiction over the party, the party ordered to produce such
information shall promptly notify the other party and shall use its best
efforts to maintain the confidentiality of such information. In addition, if
either party determines that this Agreement is a "material contract," that
party may file this Agreement with the Securities and Exchange Commission,
provided that it notifies the other party at least fifteen (15) days prior to
such filing and cooperates with the other party to seek confidential treatment
of provisions reasonably designated by the other party for such treatment. Each
party may use confidential information obtained solely as a result of this
Agreement only for the purpose of performing hereunder. Neither party may use
the other party's confidential information for any other purpose without the
express written agreement of the owner.

The parties will cooperate in taking steps to protect the confidential
information, including software, from copying by others, including Customers.
