Registration Rights Agreement shall continue to be in effect;

               (2)     The representations and warranties of the Company

financial condition of the Company that individually, or in the aggregate,
constitutes a Material Adverse Effect, as that term is defined in Section 4.5

Company's issuance of the Second Tranche Shares shall constitute the Company's
making such representation and warranty as of such date).

               (6)     The Term "Market price of the Common Stock" means, the 
closing bid price of the Common stock as reported, at the option of the

additional shares of Common Stock for no additional consideration (the "Reset
Shares") to the extent and as follows:

                    (a)     If the average Closing Bid Price of the Common Stock
for the sixty calendar day period between the Effectiveness Date and the Second
Closing Date (the "60-day Average") is less than $5.40 per share, the Company
shall issue Reset Shares in such number as shall be determined by dividing (i)
the product of (A) the amount by which the 60-day Average is less than $5.40 and
(B) 1,111,111 by (ii) the 60-day Average.

               (2)     Second Tranche Reset.  On that date which shall be the 
<PAGE>
 
next following business day after the sixtieth (60th) day after the Second

Reset Shares as provided in Section 2.3(1)(a), provided that the period for
determining the 60-day Average shall be the sixty (60) day period commencing on
the Second Closing Date.

               (3)     Issuance of Reset Shares. The Reset Shares, if any,
issued by the Company Pursuant to Section 2.3, shall be issued to each Purchaser
pro rata according to the percentage of the Purchase Price paid by each
Purchaser. The Shares and the Reset Shares shall be collectively referred to
herein as the "Securities."

               (4)     Reset Share Adjustment.  If, at any time prior to or on 
the Sixtieth (60th) day following the Second Tranche Reset Date, the Company 
shall sell, or enter into an agreement to sell, Common Stock or securities 
convertible into Common Stock at a discount of sixteen and two thirds percent 
(16.66%) or greater from the Closing Bid Price of such Common Stock at time of 
such sale or conversion, or the date of any such agreement (the "Discount 
Percentage"), whichever is less, the Company shall issue additional Reset 
Shares to each Purchaser, and such number shall be calculated as follows:

               Securities actually issued x Adjusted Yield
                                            --------------
                                             .20

               Where "Adjusted Yield" is equal to:

                           Discount Percentage
                           -------------------
                         1-Discount Percentage

               (5)     Short Sales. Purchaser covenants that it will engage in
no short sales of Common Stock during any period during which a 60-day Average
is being calculated.

          2.4     Size of Offering.  Purchaser and the Company agree that, in
addition to Purchaser's investment as contemplated by this Agreement, the
Company may offer and sell additional Securities to other investors as part of
the same offering, provided that the any additional investment shall be on the
same material terms and conditions as are herein set forth, and do not exceed,

received from the Company documents or other materials which constitute
summaries, projections, forecasts or estimates, Purchaser acknowledges the

thereto. Such financial statements were prepared in accordance with generally
accepted accounting principles applied on a consistent basis during the periods
involved (except (i) as may be otherwise indicated in such financial statements
or the notes thereto or (ii) in the case of unaudited interim statements, to the
extent they may not include footnotes or may be condensed or summary statements
as permitted by Form 10-Q of the SEC) and fairly present in all material
respects the financial position of the Company and its consolidated subsidiaries
as of the dates thereof and the consolidated results of operations and cash

award has been issued by or, to the best knowledge of the Company, requested of
any court, arbitrator or governmental agency which might result in a Material

other materials received by Purchaser from the Company or its representatives
other than the Transaction Documents and the SEC Documents, (i) the Company has

of such date, and (ii) such documents, materials and projections were prepared
by the Company and its management in good faith.

          4.15     Nature of Company. The Company is not an open ended
investment company or a unit investment trust, registered or required to be
registered, or a closed end investment company required to be registered, but
not registered, under the Investment Company Act of 1940.

          4.16     Brokers, Finders. Two entities have acted as brokers and/or
finders in connection with the transactions contemplated by this Agreement.
Payment of fees to such brokers and/or finders shall be the sole responsibility
of the Company. The Company has taken no action which would give rise to any
claim by any person for brokerage commission, finder's fees or similar payments
by Purchaser relating to this Agreement or the transactions contemplated hereby.
Purchaser shall have no obligation with respect to such fees or with respect to
any claims made by or on behalf of other Persons for fees of a type contemplated
in this Section 4.14 that may be due in connection with the transactions
contemplated hereby. The Company shall indemnify and hold harmless each of
Purchaser, their respective employees, officers, directors, agents, and
partners, and their respective affiliates, from and against all claims, losses,
damages, costs (including the costs of preparation and attorney's fees) and
expenses suffered in respect of any such claimed or existing fees, as and when
incurred. See Section 3.5.
          
          4.17     Absence of Certain Changes. Since December 31, 1996, no
Material Adverse Effect has been suffered by, and no material adverse
development has occurred in the business, properties, operations, financial
condition, results of operations or prospects of, the Company or the
Subsidiaries. The Company has not taken any steps, and does not currently expect
to take any steps, to seek protection pursuant to any bankruptcy law nor does
the Company or any of the Subsidiaries have any knowledge or reason to believe
that its creditors intend to initiate involuntary bankruptcy proceedings.

          4.18     Intellectual Property Rights. The Company and its
subsidiaries own or possess adequate rights or licenses to use all trademarks,
trade names, service marks, service mark registrations, service names, patents,
patent rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. None of the Company's trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, government authorizations,
trade secrets or other intellectual property rights have expired or terminated,
or are expected to expire or terminate in the near future. The Company and its
subsidiaries do not have any knowledge of any infringement by the Company or its
subsidiaries of trademarks, trade name rights, patents, patent rights,
copyrights, inventions, licenses, service names, service marks, service mark
registrations, trade secrets or other similar rights of others, or of any such
development of similar or identical trade secrets or technical information by
others and, there is no claim, action or proceeding being made or brought
against, or to the best knowledge of the Company, being threatened against, the
Company or its subsidiaries regarding trademark, trade name, patent, patent
rights, invention, copyright, license, service name, service mark, service mark
registration, trade secret or other infringement; and the Company and its
subsidiaries are unaware of any facts or circumstances which might give rise to
any of the foregoing. The Company and its subsidiaries have taken reasonable
security measures to protect the secrecy, confidentiality and value of all of
their intellectual properties.
          
          4.19     Internal Accounting Controls. The Company is aware of no
respect in which its system of internal accounting controls is not sufficient to
provide reasonable assurance that (i) transactions are executed in
<PAGE>
 
accordance with management's general or specific authorizations, (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain asset accountability, (iii) access to assets is permitted only in
accordance with management's general or specific authorization and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

          4.20     Tax Status. The Company and the Subsidiaries have made or
filed all federal and state income and all other tax returns, reports and
declarations required by any jurisdiction to which it is subject and has paid
all taxes and other governmental assessments and charges that are material in
amount, shown or determined to be due on such returns, reports, declarations,
except those being contested in good faith and has set aside on its books
provisions reasonably adequate for the payment of all taxes for periods
subsequent to the periods to which such returns, reports, or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction, and the officers of the Company know of no basis
for any such claim.

          4.21     Certain Transactions. Except as set forth in the SEC
Documents and except for arm's length transactions pursuant to which the Company
makes payments in the ordinary course of business upon terms no less favorable
than the Company could obtain from third parties and other than the grant of
stock options, none of the officers, directors, or employees of the Company (or
any spouse or relative of any such person) is presently a party to any
transaction with the Company (other than for services as employees, officers and
directors), including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

          4.22     Dilution. The number of shares of Common Stock issuable as
Reset Shares may increase substantially in certain circumstances, including, but
not necessarily limited to, the circumstance wherein the trading price of the
Common Stock declines during the sixty day period between the Effectiveness Date
and the Second Closing Date. The Company's executive officers and directors have
studied and fully understand the nature of the transactions contemplated by this
Agreement and recognize that they have a potential dilutive effect. The board of
directors of the Company has concluded, in its good faith business judgment,
that such issuance is in the best interests of the Company. The Company
specifically acknowledges that its obligation to issue the Reset Shares is
binding upon the Company and enforceable regardless of the dilution such
issuance may have on the ownership interests of other shareholders of the
Company.

          4.23     Nasdaq Listing. The Company's Common Stock is presently
quoted on the Nasdaq SmallCap Stock Market under the symbol "FONX". The Company
is not in receipt of any written or oral notice from any stock exchange, market
or trading facility on which the Common Stock is or has been listed (or on which
it is or has been quoted) to the effect that the Company is not in compliance
with the listing or maintenance requirements of such stock exchange, market or
trading facility or that the Common Stock will be delisted from such stock
exchange, market or trading facility. The Company is in compliance with such
listing and maintenance requirements.

     5.     Use and Disposition of Proceeds. The Company intends to use the
gross proceeds from the Shares for working capital, for acquisition activities,
to fund its ongoing research and development activities, and for
<PAGE>
 
the payment of general and administrative expenses. Purchaser acknowledges and
agrees that the Company shall have immediate access to the funds paid by
Purchaser pursuant to this Agreement according to the discretion of management
of the Company.

     6.     Company Reliance on Purchaser's Representations. Purchaser
understands that the Company is relying on the truth and accuracy of the
representations and warranties made herein by Purchaser in offering the
Securities for sale and in relying upon applicable exemptions available under
the Act and applicable state securities laws.

     7.     Restricted Shares. Purchaser understands and acknowledges that the
Securities have not been, and will not as of the time issued, registered under
the Securities Act and that they will be issued in reliance upon exemptions from
the registration requirements of the Securities Act, and thus cannot be resold
unless they are included in an effective registration statement filed under the
Securities Act or unless an exemption from registration is available for such
resale. With regard to the restrictions on resales of the Securities, Purchaser
is aware (a) that the Company will issue stop transfer orders to its stock
transfer agent in the event of attempts to improperly transfer any such
securities; and (b) that a restrictive legend will be placed on certificates
representing the Securities, which legend will read substantially as follows:

THESE SECURITIES ARE NOT REGISTERED WITH THE UNITED STATES SECURITIES AND
EXCHANGE COMMISSION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT AND REGULATIONS
PROMULGATED UNDER THE ACT, INCLUDING EXEMPTIONS UNDER SECTIONS 3(b) AND 4(2) OF
THE ACT AND THE PROVISIONS OF REGULATION D UNDER SUCH ACT, AND SIMILAR
EXEMPTIONS UNDER STATE LAW. ACCORDINGLY, THESE SECURITIES MAY NOT BE RESOLD,
TRANSFERRED, PLEDGED, ASSIGNED OR HYPOTHECATED UNLESS SUCH SECURITIES ARE
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE ACT OR AN
EXEMPTION FROM SUCH REGISTRATION REQUIREMENT IS AVAILABLE AND THE COMPANY HAS
RECEIVED AN OPINION OF SECURITIES COUNSEL REASONABLY SATISFACTORY TO THE COMPANY
THAT SUCH EXEMPTION IS AVAILABLE.

The legend set forth above shall be removed, and the Company shall issue a
certificate without such legend to the holder of any such Securities upon which
such legend is stamped promptly and, in the case of clauses (i) or (ii) below,
no later than the Delivery Date, as such term is defined below, if, unless
otherwise required by state securities laws, (i) such Securities are registered
for resale under the Securities Act, (ii) in connection with a sale transaction,
such holder provides the Company with an opinion of counsel, in a generally
acceptable form, to the effect that a public sale, assignment or transfer of
such Securities may be made without registration under the Securities Act, or
(iii) such holder provides the Company with reasonable assurances that such
Securities can be sold pursuant to Rule 144 promulgated under the Securities Act
without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold. Notwithstanding the removal
of the legend set forth above in the event the Securities are registered for
resale on an effective registration statement, the Company reserves the right to
affix a legend on certificates representing such Securities that any selling
shareholder must comply with the prospectus delivery requirements of the
Securities Act in connection with any resale. The Company shall bear the cost of
the removal of any legend as anticipated by this Section 7.

     8.     Other Covenants of the Parties.

          8.1     Furnishing of Information. As long as Purchaser owns
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
<PAGE>
 
13(a) or 15(d) of the Exchange Act.  If at any time prior to the date on which 
the Purchasers may resell all of their Securities without volume restrictions 
pursuant to Rule 144(k) promulgated under the Securities Act (as determined by 
counsel to the Company pursuant to a written opinion letter to such effect, 
addressed and acceptable to the Company's transfer agent for the benefit of 
and enforceable by Purchaser) the Company is not required to file reports 
pursuant to such sections, it will prepare and furnish to the Purchasers and 
make publicly available in accordance with Rule 144(c) promulgated under the 
Securities Act annual and quarterly financial statements, together with a 
discussion and analysis of such financial statements in form and substance 
substantially similar to those that would otherwise be required to be included 
in reports required by Section 13(a) or 15(d) of the Exchange Act in the time 
period that such filings would have been required to have been made under the 
Exchange Act.  The Company further covenants that it will take such further 
action as any holder of Securities may reasonably request, all to the extent 
required from time to time to enable such Person to sell Securities without 
registration under the Securities Act within the limitation of the exemptions 
provided by Rule 144 promulgated under the Securities Act. 

          8.2     Listing of Securities.  The Company shall (a) in accordance 
with applicable Nasdaq rules but in any event not later than the Effectiveness 
Date, prepare and file with the Nasdaq SmallCap Market (as well as any other 
national securities exchange, market or trading facility on which the Common 
Stock is then listed) an additional shares listing application covering the 
Securities, (b) take all steps necessary to cause such Securities to be 
approved for listing on the Nasdaq SmallCap Market (as well as on any other 
national securities exchange, market or trading facility on which the Common 
Stock is then listed) as soon as possible thereafter, and (c) provide to 
Purchaser evidence of such listing, and the Company shall maintain the listing 
of its Common Stock on such exchange or market. 

          8.3     First Right.    The Company shall not, directly or 
indirectly, without the prior written consent of Purchaser, offer, sell, grant 
any option to purchase, or otherwise dispose of (or announce any offer, sale, 
grant or any option to purchase or other disposition) any of its Common Stock 
or securities convertible into Common Stock at a price that is less than 
eighty percent (80%) of the market price of the Common Stock at the time of 
issuance of such security or investment (a "Subsequent Financing") for a 
period of ninety (90) days after the Second Closing Date, except (i) the 
granting of options or warrants to employees, officers and directors, and the 
issuance of shares upon exercise of options granted, under any stock option 
plan heretofore or hereinafter duly adopted by the Company, (ii) shares issued 
upon exercise of any currently outstanding warrants or options and upon 
conversion of any currently outstanding convertible preferred stock or payment 
of dividends thereon, in each case disclosed in Section 4.4 or Schedule 4.4, 
(iii) securities issued in connection with the capitalization or creation of a 
joint venture with a strategic partner, (iv) shares issued to pay part or all 
of the purchase price for the acquisition by the Company of a Person (which, 
for purposes of this clause (iv), shall not include an individual or group of 
individuals) and (v) shares issued in a bona fide public offering by the 
Company of its securities, unless (A) the Company delivers to Purchaser a 
written notice (the "Subsequent Financing Notice") of its intention effect 
such Subsequent Financing, which Subsequent Financing Notice shall describe in 
reasonable detail the proposed terms of such Subsequent Financing, the amount 
of proceeds intended to be raised thereunder, the Person with whom such 
Subsequent Financing shall be effected, and attached to which shall be a term 
sheet or similar document relating thereto and (B) Purchaser shall not have 
notified the Company by 5:00 p.m. (Salt Lake City time) on the tenth (10th) 
trading day after its receipt of the Subsequent Financing Notice of its 
willingness to cause all or any of the Purchaser to provide, subject to 
completion of mutually acceptable documentation, financing to the Company on 
substantially the terms set forth in the Subsequent Financing Notice.  If 
Purchaser shall fail to notify the Company of its intention to enter into such 
<PAGE>
 
negotiations within such time period, the Company may effect the Subsequent 
Financing substantially upon the terms and to the Persons (or Affiliates of 
such Persons) set forth in the Subsequent Financing Notice; provided, that the 
Company shall provide Purchaser with a second Subsequent Financing Notice, and 
Purchaser shall again have the right of first refusal set forth above in this 
subsection 8.4, if the Subsequent Financing subject to the initial Subsequent 
Financing Notice shall not have been consummated for any reason on the terms 
set forth in such Subsequent Financing Notice within thirty (30) trading days 
after the date of the initial Subsequent Financing Notice with the Person (or 
an Affiliate of such Person) identified in the Subsequent Financing Notice.  
Purchaser's rights under this Section 8.3 are subject to the rights of Thomson 
Kernaghan & Co., as agent for certain other entities ("Thomson") as described 
in that certain Common Stock Purchase Agreement between Thomson and the 
Company and dated as of even date herewith.

          8.4     Available Shares.  The Company shall have at all times 
authorized and reserved for issuance, free from preemptive rights, shares of 
Common Stock sufficient to yield the number of shares of Common Stock issuable 
as may be required to issue the Reset Shares.

          8.5     Stockholder Meeting.  The Company shall, not later than 
August 1, 1998, hold a regular or special meeting of stockholders.  At such 
meeting of stockholders, the board of directors of the Company shall recommend 
that the stockholders approve the transactions contemplated hereby, which 
might result in the issuance of more than 20% of the Company's outstanding 
Common Stock in accordance with NASDAQ Rule 4310(c)(25)(H)(i)(d)(2).  Thomas 
A. Murdock, as trustee of a voting trust (the "Voting Trust") pursuant to that 
certain  Voting Trust Agreement dated the 10th day of December, 1993 and as 
amended to date, by and among the Company, Stephen M. Studdert, Thomas A. 
Murdock, Roger D. Dudley, Beesmark Investments, L.C., a Utah limited liability 
company, and Studdert Companies Corporation, a Utah corporation, and Thomas A. 
Murdock, as Trustee, warrants and represents by his signature below:

          (1)     That the Voting Trust owns of record in excess of 56% of the 
Common Stock of the Company issued and outstanding as of the date of this 
Agreement; and

          (2)     That he will affirmatively vote such shares of Common Stock 
in favor of  such resolution.

          8.6     Redemption by the Company.  At any time prior to the 
ninetieth (90th) day following the Second Closing Date, the Company may redeem 
all or any of the Securities then outstanding and which have not been sold or 
contracted to be sold by Purchaser by payment to the holder of the Securities 
to be redeemed of $5.40 per share.

     9.     Transfer Agent Instructions.

          9.1     Irrevocable Instructions.  The Company will irrevocably 
instruct its transfer agent to issue securities from time to time in such 
amounts as shall be specified from time to time by the Company to the transfer 
agent, bearing the restrictive legend specified in Section 7 of this Agreement 
prior to registration of the Securities under the Securities Act, registered 
in the name of the Purchaser or its nominee and in such denominations to be 
specified by the Purchaser in connection with each Closing.  The Company 
warrants that no instruction other than such instructions referred to in this 
Section 9 and stop transfer instructions to give effect to Section 7 hereof 
prior to registration and sale of the Securities under the Securities Act will 
be given by the Company to the transfer agent and that the securities shall 
otherwise be freely transferable on the books and records of the Company as 
and to the extent provided in this Agreement, the Registration Rights 
Agreement, and applicable law.  Nothing in this Section 9 shall affect in any 
way the Purchaser's obligations and agreement to comply with all applicable 
<PAGE>
 
securities laws upon resale of the Securities. 

          9.2     Transmission of Certificates.  The Company will transmit the 
certificates representing the unlegended Securities to be issued to the 
Purchaser (i) as Reset Shares pursuant to any of the provisions of Section 2.3 
hereof and/or (ii) as contemplated by Section 7 hereof.  The term "Delivery 
Date" means (w) the Second Closing Date, with respect to Reset Shares 
contemplated by Section 2.3(1) hereof, (x) the Second Tranche Reset Date, with 
respect to Reset Shares contemplated by Section 2.3(2) hereof, (y) the third 
(3rd) business day after receipt by the Company of the certificate(s) 
representing the legended Common Stock, as contemplated by Section 7 hereof.

          9.3     Delay.  The Company understands that a delay in the issuance 
of the Securities beyond the Delivery Date could result in economic loss to 
the Purchaser.  As compensation to the Purchaser for such loss, the Company 
agrees to pay late payments to the Purchaser for late issuance of unlegended 
securities in accordance with the following schedule (where "No.  Days Late" 
is defined as the number of days beyond five (5) business days from Delivery 
Date):

                                   Late Payment For Each
          No. Days Late               $10,000 of Common Stock    

                 1                         $100
                 2                         $200
                 3                         $300
                 4                         $400
                 5                         $500
                 6                         $600
                 7                         $700
                 8                         $800
                 9                         $900
                10                         $1,000
   Greater than 10                         $1,000 +$200 for each Business
                                                   Day Late beyond 10 days

The Company shall pay any payments incurred under this Section 9.4 in 
immediately available funds upon demand.  Nothing herein shall limit the 
Purchaser's right to pursue actual damages for the Company's failure to issue 
and deliver the unlegended securities to the Purchaser.  

          9.4     Cover.  If, by the relevant Delivery Date, the Company fails 
for any reason to deliver the unlegended Shares to be issued pursuant to 
Section 9.2 and after such Delivery Date, the holder of the securities (a 
"Holder") purchases, in an open market transaction or otherwise, shares of 
Common Stock (the "Covering Shares") in order to make delivery in satisfaction 
of a sale of Common Stock by the Holder (the "Sold Shares"), which delivery 
such Holder anticipated to make using the Shares to be issued upon such 
conversion (a "Buy-In"), the Company shall pay to the Holder, in addition to 
all other amounts contemplated in other provisions of the Transaction 
Agreements, and not in lieu thereof, the Buy-In Adjustment Amount (as defined 
below).  The "Buy-In Adjustment Amount" is the amount equal to the excess, if 
any, of (x) the Holder's total purchase price (including brokerage 
commissions, if any) for the Covering Shares over (y) the net proceeds  (after 
brokerage commissions, if any) received by the Holder from the sale of the  
Sold Shares.  The Company shall pay the Buy-In Adjustment Amount to the 
Company in immediately available funds immediately upon demand by the Holder.  
By way of illustration and not in limitation of the foregoing, if the Holder 
purchases shares of Common Stock having a total purchase price (including 
brokerage commissions) of $11,000 to cover a Buy-In with respect to shares of 
Common Stock it sold for net proceeds of $10,000, the Buy-In Adjustment Amount 
which Company will be required to pay to the Holder will be $1,000.
<PAGE>
 
          9.5     Electronic Transfer.  In lieu of delivering physical 
certificates representing the unlegended securities issuable upon conversion, 
provided the Company's transfer agent is participating in the Depository Trust 
Company ("DTC") Fast Automated Securities Transfer program, upon request of 
the Purchaser and its compliance with the provisions contained in this 
paragraph, so long as the certificates therefor do not bear a legend and the 
Purchaser thereof is not obligated to return such certificate for the 
placement of a legend thereon, the Company shall use its best efforts to cause 
its transfer agent to electronically transmit the Common Stock issuable upon 
conversion to the Purchaser by crediting the account of Purchaser's Prime 
Broker with DTC through its Deposit Withdrawal Agent Commission system.

     10.     General Provisions.
     
          10.1     Assignment.  Neither this Agreement nor any rights of 
Purchaser hereunder may be assigned by either party to any other person 
without the prior written consent of the Company, provided that Purchaser may 
assign its rights hereunder to another Purchaser or to any affiliate of the 
Purchaser.  

          10.2     Attorneys' Fees.  In the event any dispute arises under 
this Agreement or the documents or instruments executed and delivered in

resolve such dispute, the prevailing party in any such litigation, in addition 
to all other remedies at law or in equity, shall be entitled to an award of

          10.3     Choice of Law; Venue.  This Agreement will be construed and 
enforced in accordance with and governed by the laws of the State of Delaware

conflicts of law.  The parties agree that, in the event of any dispute arising 
out this Agreement or the transactions contemplated thereby, venue for such 
dispute shall be in the state or federal courts located in Delaware, and that 
each party hereto waives any objection to such venue based on forum non 
conveniens.

          10.4     Costs and Expenses.  The parties shall be responsible for 
and shall pay their own costs and expenses, including without limitation 
attorneys' fees and accountants' fees and expenses, in connection with the

this Agreement and the instruments, documents and agreements executed in

          10.5     Counterparts/Facsimile Signatures.  This Agreement may be 
executed in one or more counterparts, each of which when so signed shall be 
deemed to be an original, and such counterparts together shall constitute one 
and the same instrument.  In lieu of the original, a facsimile transmission or 
copy of the original shall be as effective and enforceable as the original.
          
          10.6     Entire Agreement: Amendment.  This Agreement, together with 
the exhibits to this Agreement and the other instruments and documents 
delivered in connection with this Agreement constitute the full and entire 
understanding and agreement between the parties with regard to the subjects 
hereof and thereof, and no party shall be liable or bound to any other party

specifically set forth in this Agreement or therein.  Except as expressly 
provided in this Agreement, neither this Agreement nor any term hereof may be 
amended, waived, discharged or terminated other than by a written instrument 
signed by the party against whom enforcement of any such amendment, waiver, 
discharge or termination is sought.

          10.9     Publicity.  Purchaser shall not issue any press release or 
otherwise make any public statement about the transactions contemplated by

agrees that it shall give Purchaser written notice of any press release or 
other public statement with respect to the transactions contemplated hereby.  
Notwithstanding the foregoing, the Company shall not publicly disclose the 
name of Purchaser without the prior written consent of such Purchaser, except

all or part of the Transaction Documents may be deemed to be "material 
contracts" as that term is defined by Item 601(b)(10) of Regulation S-K, and

Exchange Act.  Purchaser further agrees that the status of such documents and 
materials as material contracts shall be determined solely by the Company, in 
consultation with its counsel.

          10.10     Severability.  Should any one or more of the provisions of 
this Agreement be determined to be illegal or unenforceable, all other 
provisions of this Agreement shall be given effect separately from the 
provision or provisions determined to be illegal or unenforceable and shall 
not be affected thereby.

          10.11     Survival.  All warranties, representations, indemnities 
and agreements made in this Agreement by a party hereto shall survive the date 
of this Agreement, the Closing Dates, and the issuance by the Company of the 
Securities.

corporation (the "Company"),  JNC Opportunity Fund Ltd., a Cayman Islands 
corporation ("JNC"), and Diversified Strategies Fund, L.P., an Illinois 
limited partnership ("DSF") (JNC and DSF are each a "Purchaser" and 
collectively the "Purchasers").

          This Agreement is made pursuant to the Common Stock Purchase 
Agreement, dated as of the date hereof among the Company and the Purchasers 
(the "Purchase Agreement").

          The Company and the Purchasers hereby agree as follows:

     1.     Definitions

          Capitalized terms used and not otherwise defined herein that are 
defined in the Purchase Agreement shall have the meanings given such terms in 
the Purchase Agreement.  As used in this Agreement, the following terms shall 
have the following meanings:

          "Affiliate" means, with respect to any Person, any other Person that 
directly or indirectly controls or is controlled by or under common control 
with such Person.  For the purposes of this definition, "control," when used 
with respect to any Person, means the possession, direct or indirect, of the 
power to direct or cause the direction of the management and policies of such 
Person, whether through the ownership of voting securities, by contract or 
otherwise; and the terms "affiliated," "controlling" and "controlled" have 
meanings correlative to the foregoing.

          "Business Day" means any day except Saturday, Sunday and any day 
which shall be a legal holiday or a day on which banking institutions in the 
state of Delaware generally are authorized or required by law or other 
government actions to close.

          "Initial Closing Date" shall have the meaning set forth in the 
Purchase Agreement.

          "Commission" means the Securities and Exchange Commission.

          "Common Stock" means the Company's Common Stock, par value $.0001 
per share.

          "Effectiveness Date" means the first to occur of (i) the 90th day 
following the Initial Closing Date or (ii) the fifth (5th) trading day 
following receipt by the Company of notice, orally or in writing, that the 
Commission either will not review the Registration Statement or will allow the 
Registration Statement to become effective.

          "Effectiveness Period" shall have the meaning set forth in Section 
2(a).

          "Exchange Act" means the Securities Exchange Act of 1934, as 
amended.

          "Filing Date" means the 30th day following the Initial Closing Date.

          "Person" means an individual or a corporation, partnership, trust, 
incorporated or unincorporated association, joint venture, limited liability 
company, joint stock company, government (or an agency or political 
subdivision thereof) or other entity of any kind.

          "Proceeding" means an action, claim, suit, investigation or

proceeding, such as a deposition), whether commenced or threatened.

information previously omitted from a prospectus filed as part of an effective 
registration statement in reliance upon Rule 430A promulgated under the 
Securities Act), as amended or supplemented by any prospectus supplement, with 
respect to the terms of the offering of any portion of the Registrable 
Securities covered by the Registration Statement, and all other amendments and 
supplements to the Prospectus, including post-effective amendments, and all 
material incorporated by reference or deemed to be incorporated by reference 
in such Prospectus.

          "Registrable Securities" means the Securities; provided, however 
that in order to account for the fact that the number of shares of Reset 
Shares that are or will be issuable at the Second Closing will be determined 
in part upon the market price of the Common Stock between the Initial Closing 
Date and the Effective Date, Registrable Securities contemplated by this 
definition shall be deemed to include not less than the number of shares of 
Common Stock issuable at the Second Closing assuming that the 60-day Average 
is $3.25.  The Registration Statement shall cover at least such number of 
shares of Common Stock as equals the sum of the number of Shares plus the 
amount of Reset Shares assuming the 60-day Average set forth in the 
immediately preceding sentence.  To the extent that an additional Registration 
Statement is required at any time to include the full amount of the Securities 
as then are issued and outstanding, the Company covenants to file such 
additional Registration Statement within ten (10) business days after notice 
from Purchasers that such additional Registration Statement is required.

          "Registration Statement" means the registration statement 
contemplated by Section 2(a), including the Prospectus, amendments and 
supplements to such registration statement or Prospectus, including pre- and

statement.

          "Rule 158" means Rule 158 promulgated by the Commission pursuant to 
the Securities Act, as such Rule may be amended from time to time, or any 
similar rule or regulation hereafter adopted by the Commission having

the Securities Act, as such Rule may be amended from time to time, or any 
similar rule or regulation hereafter adopted by the Commission having 
substantially the same effect as such Rule.
<PAGE>
 
          "Securities Act" means the Securities Act of 1933, as amended.

          "Special Counsel" means the law firm acting as counsel to the 
Holders, for which the Holders will be reimbursed by the Company pursuant to 
Section 4.

          "Underwritten Registration or Underwritten Offering" means a 
registration in connection with which securities of the Company are sold to an 
underwriter for reoffering to the public pursuant to an effective registration 
statement.

     2.     Shelf Registration

          (a)     On or prior to the Filing Date the Company shall prepare and 
file with the Commission a "Shelf" Registration Statement covering all 
Registrable Securities for an offering to be made on a continuous basis 
pursuant to Rule 415.  Such Registration Statement shall state that in 
accordance with Rules 416 and 457 under the Securities Act, it also covers 
such indeterminate shares of Common Stock as may be issuable as Reset Shares.  
The Registration Statement shall be on Form S-3 promulgated under the 
Securities Act (or, if the Company is not permitted to register the resale of 
the Registrable Securities on Form S-3, the Registration Statement shall be on 
such other appropriate form).  The Company shall use its best efforts to cause 
the Registration Statement to be declared effective under the Securities Act 
as promptly as possible after the filing thereof, but in any event prior to 
the Effectiveness Date, and shall use its best efforts to keep such 
Registration Statement continuously effective under the Securities Act until 
the date which is two years after the date that such Registration Statement is 
declared effective by the Commission or such earlier date when all Registrable 
Securities covered by such Registration Statement have been sold or may be 
sold without volume restrictions pursuant to Rule 144(k) promulgated under the 
Securities Act, as determined by the counsel to the Company pursuant to a 
written opinion letter to such effect, addressed and acceptable to the 
Company's transfer agent (the "Effectiveness Period").   In the event that (i) 
the Registration Statement shall not have become effective by the 
Effectiveness Date or (ii) the Registration Statement shall have become 
effective by the Effectiveness Date, but shall thereafter cease to be 
effective for two 20-day trading day periods during any 12-month period during 
the Effectiveness Period, then the Company shall pay to the Purchasers, pro 
rata, and as liquidated damages and not as a penalty, cash payment in the 
amount of 2% of the Purchase Price paid by Purchasers to date, in the case of 
clause (i) above, for each month after the Effectiveness Date or, in the case 
of clause (ii) above, for each additional 20-day period during which the 
Registration Statement shall not be effective.  The Company shall not be 
deemed to have used its best efforts to keep the Registration Statement 
effective during the Effectiveness Period if it voluntarily takes any action 
that would result in the Holders not being able to sell all of the Registrable 
Securities covered by such Registration Statement during the Effectiveness 
Period, unless such action is required under applicable law or the Company has 
filed a post-effective amendment to the Registration Statement and the 
Commission has not declared it effective.

          (b)     If the Holders of a majority of the Registrable Securities 
so elect, an offering of Registrable Securities pursuant to the Registration 
Statement may be effected in the form of an Underwritten Offering.  In such 
event, the investment banker that will administer the offering will be 
selected by the Holders of a majority of the Registrable Securities to be 
included in such offering.  In connection with any Underwritten Offering, if 
the managing underwriters advise the Company and the participating Holders in 
writing that in their opinion the amount of Registrable Securities proposed to 
be sold in such Underwritten Offering exceeds the amount of Registrable 
Securities which can be sold in such Underwritten Offering, there shall be 
<PAGE>
 
included in such Underwritten Offering the amount of such Registrable 
Securities which in the opinion of such managing underwriters can be sold, and 
such amount shall be allocated pro rata among the Holders proposing to sell 
Registrable Securities in such Underwritten Offering.  No Holder may 
participate in any Underwritten Offering hereunder unless such Holder (i) 
agrees to sell its Registrable Securities on the basis provided in any 
underwriting agreements approved by the Persons entitled hereunder to approve 
such arrangements and (ii) completes and executes all questionnaires, powers 
of attorney, indemnities, underwriting agreements and other documents required 
under the terms of such arrangements.

     3.     Registration Procedures

          In connection with the Company's registration obligations hereunder, 
the Company shall:

          (a)     Prepare and file with the Commission on or prior to the 
Filing Date, a Registration Statement in accordance with Section 2(a), and 
cause the Registration Statement to become effective and remain effective as 
provided herein; provided, however, that not less than five (5) Business Days 
prior to the filing of the Registration Statement or any related Prospectus or 
any amendment or supplement thereto (including any document that would be 
incorporated or deemed to be incorporated therein by reference), the Company 
shall (i) furnish to the Holders, their Special Counsel and any managing 
underwriters, copies of all such documents proposed to be filed, which 
documents (other than those incorporated or deemed to be incorporated by 
reference) will be subject to the review of such Holders, their Special 
Counsel and such managing underwriters, and (ii) cause its officers and 
directors, counsel and independent certified public accountants to respond to 
such inquiries as shall be necessary, in the opinion of respective counsel to 
such Holders and such underwriters, to conduct a reasonable investigation 
within the meaning of the Securities Act.  The Company shall not file the 
Registration Statement or any such Prospectus or any amendments or supplements 
thereto if the Holders of a majority of the Registrable Securities, their 
Special Counsel, or any managing underwriters, shall reasonably object on a 
timely basis.

          (b)     (i)  Prepare and file with the Commission such amendments, 
including post-effective amendments, to the Registration Statement as may be 
necessary to keep the Registration Statement continuously effective as to all 
Registrable Securities for the Effectiveness Period and prepare and file with 
the Commission such additional Registration Statements in order to register 
for resale under the Securities Act all of the Registrable Securities; (ii) 
cause the related Prospectus to be amended or supplemented by any required 
Prospectus supplement, and as so supplemented or amended to be filed pursuant 
to Rule 424 (or any similar provisions then in force) promulgated under the 
Securities Act; (iii) respond as promptly as practicable to any comments 
received from the Commission with respect to the Registration Statement or any 
amendment thereto and promptly provide the Holders true and complete copies of 
all correspondence from and to the Commission relating to the Registration 
Statement; and (iv) comply with the provisions of the Securities Act and the 
Exchange Act with respect to the disposition of all Registrable Securities 
covered by the Registration Statement during the applicable period in 
accordance with the intended methods of disposition by the Holders thereof set 
forth in the Registration Statement as so amended or in such Prospectus as so 
supplemented.

          (c)     Notify the Holders of Registrable Securities to be sold, 
their Special Counsel and any managing underwriters immediately (and, in the 
case of (i)(A) below, not less than five (5) days prior to such filing) and 
(if requested by any such Person) confirm such notice in writing no later than 
one (1) Business Day following the day (i)(A) when a Prospectus or any 
Prospectus supplement or post-effective amendment to the Registration 
<PAGE>
 
Statement is proposed to be filed; (B) whenever the Commission notifies the 
Company whether there will be a "review" of such Registration Statement; (C) 
whenever the Company receives (or representatives of the Company receive on 
its behalf) any oral or written comments from the Commission in respect of a 
Registration Statement (copies or, in the case of oral comments, summaries of 
such comments shall be promptly furnished by the Company to the Holders); and 
(D) with respect to the Registration Statement or any post-effective 
amendment, when the same has become effective; (ii) of any request by the 
Commission or any other Federal or state governmental authority for amendments 
or supplements to the Registration Statement or Prospectus or for additional 
information; (iii) of the issuance by the Commission of any stop order 
suspending the effectiveness of the Registration Statement covering any or all 
of the Registrable Securities or the initiation of any Proceedings for that 
purpose; (iv) if at any time any of the representations and warranties of the 
Company contained in any agreement (including any underwriting agreement) 
contemplated hereby ceases to be true and correct in all material respects; 
(v) of the receipt by the Company of any notification with respect to the 
suspension of the qualification or exemption from qualification of any of the 
Registrable Securities for sale in any jurisdiction, or the initiation or 
threatening of any Proceeding for such purpose; and (vi) of the occurrence of 
any event that to the best knowledge of the Company makes any statement made 
in the Registration Statement or Prospectus or any document incorporated or 
deemed to be incorporated therein by reference untrue in any material respect 
or that requires any revisions to the Registration Statement, Prospectus or 
other documents so that, in the case of the Registration Statement or the 
Prospectus, as the case may be, it will not contain any untrue statement of a 
material fact or omit to state any material fact required to be stated therein 
or necessary to make the statements therein, in light of the circumstances 
under which they were made, not misleading.  In addition, the Company shall 
furnish the Holders with copies of all intended written responses to the 
comments contemplated in clause (C) of this Section 3(c) not later than one 
(1) Business Day in advance of the filing of such responses with the 
Commission so that the Holders shall have the opportunity to comment thereon. 

          (d)     Use its best efforts to avoid the issuance of, or, if 
issued, obtain the withdrawal of (i) any order suspending the effectiveness of 
the Registration Statement or (ii) any suspension of the qualification (or 
exemption from qualification) of any of the Registrable Securities for sale in 
any jurisdiction, at the earliest practicable moment.

          (e)     If requested by any managing underwriter or the Holders of a 
majority in interest of the Registrable Securities to be sold in connection 
with an Underwritten Offering, (i) promptly incorporate in a Prospectus 
supplement or post-effective amendment to the Registration Statement such 
information as such managing underwriters and such Holders reasonably agree 
should be included therein and (ii) make all required filings of such 
Prospectus supplement or such post-effective amendment as soon as practicable 
after the Company has received notification of the matters to be incorporated 
in such Prospectus supplement or post-effective amendment; provided, however, 
that the Company shall not be required to take any action pursuant to this 
Section 3(e) that would, in the opinion of counsel for the Company, violate 
applicable law or be materially detrimental to the business prospects of the 
Company.

          (f)     Furnish to each Holder, their Special Counsel and any 
managing underwriters, without charge, at least one conformed copy of each 
Registration Statement and each amendment thereto, including financial 
statements and schedules, all documents incorporated or deemed to be 
incorporated therein by reference, and all exhibits to the extent requested by 
such Person (including those previously furnished or incorporated by 
reference) promptly after the filing of such documents with the Commission.

          (g)     Promptly deliver to each Holder, their Special Counsel, and 
<PAGE>
 
any underwriters, without charge, as many copies of the Prospectus or 
Prospectuses (including each form of prospectus) and each amendment or 
supplement thereto as such Persons may reasonably request; and the Company 
hereby consents to the use of such Prospectus and each amendment or supplement 
thereto by each of the selling Holders and any underwriters in connection with 
the offering and sale of the Registrable Securities covered by such Prospectus 
and any amendment or supplement thereto.

          (h)     Prior to any public offering of Registrable Securities, use 
its best efforts to register or qualify or cooperate with the selling Holders, 
any underwriters and their Special Counsel in connection with the registration 
or qualification (or exemption from such registration or qualification) of 
such Registrable Securities for offer and sale under the securities or Blue 
Sky laws of such jurisdictions as any Holder or underwriter requests in 
writing, to keep each such registration or qualification (or exemption 
therefrom) effective during the Effectiveness Period and to do any and all 
other acts or things necessary or advisable to enable the disposition in such 
jurisdictions of the Registrable Securities covered by a Registration 
Statement; provided, however, that the Company shall not be required to 
qualify generally to do business in any jurisdiction where it is not then so 
qualified or to take any action that would subject it to general service of 
process in any such jurisdiction where it is not then so subject or subject 
the Company to any material tax in any such jurisdiction where it is not then 
so subject.

          (i)     Cooperate with the Holders and any managing underwriters to 
facilitate the timely preparation and delivery of certificates representing 
Registrable Securities to be sold pursuant to a Registration Statement, which 
certificates shall be free of all restrictive legends, and to enable such 
Registrable Securities to be in such denominations and registered in such 
names as any such managing underwriters or Holders may request at least three 
Business Days prior to any sale of Registrable Securities.

          (j)     Upon the occurrence of any event contemplated by Section 
3(c)(vi), as promptly as practicable, prepare a supplement or amendment, 
including a post-effective amendment, to the Registration Statement or a 
supplement to the related Prospectus or any document incorporated or deemed to 
be incorporated therein by reference, and file any other required document so 
that, as thereafter delivered, neither the Registration Statement nor such 
Prospectus will contain an untrue statement of a material fact or omit to 
state a material fact required to be stated therein or necessary to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading.

          (k)     Use its best efforts to cause all Registrable Securities 
relating to such Registration Statement to be listed on the Nasdaq SmallCap 
Market and any other securities exchange, quotation system, market or 
over-the-counter bulletin board, if any, on which similar securities issued by 
the Company are then listed as and when required pursuant to the Purchase 
Agreement.

          (l)     In the case of an Underwritten Offering, enter into such 
agreements (including an underwriting agreement in form, scope and substance 
as is customary in Underwritten Offerings) and take all such other actions in 
connection therewith (including those reasonably requested by any managing 
underwriters and the Holders of a majority of the Registrable Securities being 
sold) in order to expedite or facilitate the disposition of such Registrable 
Securities, and whether or not an underwriting agreement is entered into, (i) 
make such representations and warranties to such Holders and such underwriters 
as are customarily made by issuers to underwriters in underwritten public 
offerings, and confirm the same if and when requested; (ii) obtain and deliver 
copies thereof to each Holder and the managing underwriters, if any, of 
opinions of counsel to the Company and updates thereof addressed to each 
<PAGE>
 
selling Holder and each such underwriter, in form, scope and substance 
reasonably satisfactory to any such managing underwriters and Special Counsel 
to the selling Holders covering the matters customarily covered in opinions 
requested in Underwritten Offerings and such other matters as may be 
reasonably requested by such Special Counsel and underwriters; (iii) 
immediately prior to the effectiveness of the Registration Statement or at the 
time of delivery of any Registrable Securities sold pursuant thereto (at the
option of the underwriters), obtain and deliver copies to the Holders and the
managing underwriters, if any, of "cold comfort" letters and updates thereof 
from the independent certified public accountants of the Company (and, if 
necessary, any other independent certified public accountants of any 
subsidiary of the Company or of any business acquired by the Company for which 
financial statements and financial data is, or is required to be, included in 
the Registration Statement), addressed to each Person and in such form and 
substance as are customary in connection with Underwritten Offerings; (iv) if 
an underwriting agreement is entered into, the same shall contain 
indemnification provisions and procedures no less favorable to the selling 
Holders and the underwriters, if any, than those set forth in Section 7 (or 
such other provisions and procedures acceptable to the managing underwriters, 
if any, and holders of a majority of Registrable Securities participating in 
such Underwritten Offering; and (v) deliver such documents and certificates as 
may be reasonably requested by the Holders of a majority of the Registrable 
Securities being sold, their Special Counsel and any managing underwriters to 
evidence the continued validity of the representations and warranties made 
pursuant to clause 3(l)(i) above and to evidence compliance with any customary 
conditions contained in the underwriting agreement or other agreement entered 
into by the Company.

          (m)     Make available for inspection by the selling Holders, any 
representative of such Holders, any underwriter participating in any 
disposition of Registrable Securities, and any attorney or accountant retained 
by such selling Holders or underwriters, at the offices where normally kept, 
during reasonable business hours, all financial and other records, pertinent 
corporate documents and properties of the Company and its subsidiaries, and 
cause the officers, directors, agents and employees of the Company and its 
subsidiaries to supply all information in each case requested by any such 
Holder, representative, underwriter, attorney or accountant in connection with 
the Registration Statement; provided, however, that any information that is 
determined in good faith by the Company in writing to be of a confidential 
nature at the time of delivery of such information shall be kept confidential 
by such Persons, unless (i) disclosure of such information is required by 
court or administrative order or is necessary to respond to inquiries of 
regulatory authorities; (ii) disclosure of such information, in the opinion of 
counsel to such Person, is required by law; (iii) such information becomes 
generally available to the public other than as a result of a disclosure or 
failure to safeguard by such Person; or (iv) such information becomes 
available to such Person from a source other than the Company and such source 
is not known by such Person to be bound by a confidentiality agreement with 
the Company.

          (n)     Comply with all applicable rules and regulations of the 
Commission and make generally available to its security holders earning 
statements satisfying the provisions of Section 11(a) of the Securities Act 
and Rule 158 not later than 45 days after the end of any 12-month period (or 
90 days after the end of any 12-month period if such period is a fiscal year) 
(i) commencing at the end of any fiscal quarter in which Registrable 
Securities are sold to underwriters in a firm commitment or best efforts 
Underwritten Offering and (ii) if not sold to underwriters in such an 
offering, commencing on the first day of the first fiscal quarter of the 
Company after the effective date of the Registration Statement, which 
statement shall cover said 12-month period, or end shorter periods as is 
consistent with the requirements of Rule 158.
<PAGE>
 
          (o)     The Company may require each selling Holder to furnish to 
the Company such information regarding the distribution of such Registrable 
Securities as is required by law to be disclosed in the Registration Statement 
and the Company may exclude from such registration the Registrable Securities 
of any such Holder who unreasonably fails to furnish such information within a 
reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or 
otherwise as the holder of any securities of the Company, then such Holder 
shall have the right to require (i) the inclusion therein of language, in form 
and substance reasonably satisfactory to such Holder, to the effect that the 
ownership by such Holder of such securities is not to be construed as a 
recommendation by such Holder of the investment quality of the Company's 
securities covered thereby and that such ownership does not imply that such 
Holder will assist in meeting any future financial requirements of the 
Company, or (ii) if such reference to such Holder by name or otherwise is not 
required by the Securities Act or any similar Federal statute then in force, 
the deletion of the reference to such Holder in any amendment or supplement to 
the Registration Statement filed or prepared subsequent to the time that such 
reference ceases to be required.

          Each Holder agrees by its acquisition of such Registrable Securities 
that (i) it will not offer or sell any Registrable Securities under the 
Registration Statement until it has received copies of the Prospectus as then 
amended or supplemented as contemplated in Section 3(g) and notice from the 
Company that such Registration Statement and any post-effective amendments 
thereto have become effective as contemplated by Section 3(c) and (ii) it will 
comply with the prospectus delivery requirements of the Securities Act as 
applicable to it in connection with sales of Registrable Securities pursuant 
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities 
that, upon receipt of a notice from the Company of the occurrence of any event 
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 
3(c)(vi), such Holder will forthwith discontinue disposition of such 
Registrable Securities until such Holder's receipt of the copies of the 
supplemented Prospectus and/or amended Registration Statement contemplated by 
Section 3(j), or until it is advised in writing (the "Advice") by the Company 
that the use of the applicable Prospectus may be resumed, and, in either case, 
has received copies of any additional or supplemental filings that are 
incorporated or deemed to be incorporated by reference in such Prospectus or 
Registration Statement.

          4.     Registration Expenses

          (a)     All fees and expenses incident to the performance of or 
compliance with this Agreement by the Company shall, except as and to the 
extent specified in Section 4(b), be borne by the Company whether or not 
pursuant to an Underwritten Offering and whether or not the Registration 
Statement is filed or becomes effective and whether or not any Registrable 
Securities are sold pursuant to the Registration Statement.  The fees and 
expenses referred to in the foregoing sentence shall include, without 
limitation, (i) all registration and filing fees (including, without 
limitation, fees and expenses (A) with respect to filings required to be made 
with The Nasdaq Stock Market, Inc. and Nasdaq SmallCap Market and each other 
securities exchange or market or over-the-counter bulletin board on which 
Registrable Securities are required hereunder to be listed and (B) in 
compliance with state securities or Blue Sky laws (including, without 
limitation, fees and disbursements of counsel for the underwriters or Holders 
in connection with Blue Sky qualifications of the Registrable Securities and 
determination of the eligibility of the Registrable Securities for investment 
under the laws of such jurisdictions as the managing underwriters, if any, or 
the Holders of a majority of Registrable Securities may designate)), (ii) 
<PAGE>
 
printing expenses (including, without limitation, expenses of printing 
certificates for Registrable Securities and of printing prospectuses if the 
printing of prospectuses is requested by the managing underwriters, if any, or 
by the holders of a majority of the Registrable Securities included in the 
Registration Statement), (iii) messenger, telephone and delivery expenses, 
(iv) fees and disbursements of counsel for the Company, (v) Securities Act 
liability insurance, if the Company so desires such insurance, (vi) fees and 
expenses of all other Persons retained by the Company in connection with the 
consummation of the transactions contemplated by this Agreement, and (vii) 
actual fees and expenses of Special Counsel to the Holders in an amount not to 
exceed, in the aggregate for any Registration Statement, three thousand five 
hundred dollars ($3,500).  In addition, the Company shall be responsible for 
all of its internal expenses incurred in connection with the consummation of 
the transactions contemplated by this Agreement (including, without 
limitation, all salaries and expenses of its officers and employees performing 
legal or accounting duties), the expense of any annual audit, the fees and 
expenses incurred in connection with the listing of the Registrable Securities 
on any securities exchange as required hereunder.

          (b)     If the Holders require an Underwritten Offering pursuant to 
the terms hereof, the Company shall be responsible for all costs, fees and 
expenses in connection therewith, except for the fees and disbursements of the 
Underwriters (including any underwriting commissions and discounts) and their 
legal counsel and accountants, which shall be borne by the Holders and the 
Underwriters.  By way of illustration which is not intended to diminish from 
the provisions of Section 4(a), the Holders shall not be responsible for, and 
the Company shall be required to pay the fees or disbursements incurred by the 
Company (including by its legal counsel and accountants) in connection with, 
the preparation and filing of a Registration Statement and related Prospectus 
for such offering, the maintenance of such Registration Statement in 
accordance with the terms hereof, the listing of the Registrable Securities in 
accordance with the requirements hereof, and printing expenses incurred to 
comply with the requirements hereof.

     5.     Indemnification

          (a)     Indemnification by the Company.  The Company shall, 
notwithstanding any termination of this Agreement and without limitation as to 
time, indemnify and hold harmless each Holder, the officers, directors, agents 
(including any underwriters retained by such Holder in connection with the 
offer and sale of Registrable Securities), brokers (including brokers who 
offer and sell Registrable Securities as principal as a result of a pledge or 
any failure to perform under a margin call of Common Stock), investment 
advisors and employees of each of them, each Person who controls any such 
Holder (within the meaning of Section 15 of the Securities Act or Section 20 
of the Exchange Act) and the officers, directors, agents and employees of each 
such controlling Person, to the fullest extent permitted by applicable law, 
from and against any and all losses, claims, damages, liabilities, costs 
(including, without limitation, costs of preparation and attorneys' fees) and 
expenses (collectively, "Losses"), as incurred, arising out of or relating to 
any untrue or alleged untrue statement of a material fact contained in the 
Registration Statement, any Prospectus or any form of prospectus or in any 
amendment or supplement thereto or in any preliminary prospectus, or arising 
out of or relating to any omission or alleged omission of a material fact 
required to be stated therein or necessary to make the statements therein (in 
the case of any Prospectus or form of prospectus or supplement thereto, in 
light of the circumstances under which they were made) not misleading, except 
to the extent, but only to the extent, that such untrue statements or 
omissions are based solely upon information regarding such Holder furnished in 
writing to the Company by or on behalf of such Holder expressly for use 
therein, which information was reasonably relied on by the Company for use 
therein or to the extent that such information relates to such Holder or such 
Holder's proposed method of distribution of Registrable Securities and was 
<PAGE>
 
reviewed and expressly approved in writing by such Holder expressly for use in 
the Registration Statement, such Prospectus or such form of Prospectus or in 
any amendment or supplement thereto.  The Company shall notify the Holders 
promptly of the institution, threat or assertion of any Proceeding of which 
the Company is aware in connection with the transactions contemplated by this 
Agreement.

          (b)     Indemnification by Holders.  Each Holder shall, severally 
and not jointly, indemnify and hold harmless the Company, its directors, 
officers, agents and employees, each Person who controls the Company (within 
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange 
Act), and the directors, officers, agents or employees of such controlling 
Persons, to the fullest extent permitted by applicable law, from and against 
all Losses (as determined by a court of competent jurisdiction in a final 
judgment not subject to appeal or review) arising solely out of or based 
solely upon any untrue statement of a material fact or alleged untrue 
statement of material fact contained in the Registration Statement, any 
Prospectus, or any form of prospectus, or arising solely out of or based 
solely upon any omission or alleged omission of a material fact required to be 
stated therein or necessary to make the statements therein not misleading to 
the extent, but only to the extent, that such untrue statement or omission is 
contained in any information so furnished in writing by such Holder to the 
Company specifically for inclusion in the Registration Statement or such 
Prospectus and that such information was reasonably relied upon by the Company 
for use in the Registration Statement, such Prospectus or such form of 
prospectus or to the extent that such information relates to such Holder or 
such Holder's proposed method of distribution of Registrable Securities and 
was reviewed and expressly approved in writing by such Holder expressly for 
use in the Registration Statement, such Prospectus or such form of 
Prospectus.  In no event shall the liability of any selling Holder hereunder 
be greater in amount than the dollar amount of the net proceeds received by 
such Holder upon the sale of the Registrable Securities giving rise to such 
indemnification obligation.

          (c)     Conduct of Indemnification Proceedings. If any Proceeding 
shall be brought or asserted against any Person entitled to indemnity 
hereunder (an "Indemnified Party"), such Indemnified Party promptly shall 
notify the Person from whom indemnity is sought (the "Indemnifying Party") in 
writing, and the Indemnifying Party shall assume the defense thereof, 
including the employment of independent outside counsel reasonably 
satisfactory to the Indemnified Party and the payment of all fees and expenses 
incurred in connection with defense thereof; provided, that the failure of any 
Indemnified Party to give such notice shall not relieve the Indemnifying Party 
of its obligations or liabilities pursuant to this Agreement, except (and 
only) to the extent that it shall be finally determined by a court of 
competent jurisdiction (which determination is not subject to appeal or 
further review) that such failure shall have proximately and materially 
adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel 
in any such Proceeding and to participate in the defense thereof, but the fees 
and expenses of such counsel shall be at the expense of such Indemnified Party 
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay 
such fees and expenses; or (2) the Indemnifying Party shall have failed 
promptly to assume the defense of such Proceeding and to employ counsel 
reasonably satisfactory to such Indemnified Party in any such Proceeding; or 
(3) the named parties to any such Proceeding (including any impleaded parties) 
include both such Indemnified Party and the Indemnifying Party, and such 
Indemnified Party shall have been advised by counsel that a conflict of 
interest is likely to exist if the same counsel were to represent such 
Indemnified Party and the Indemnifying Party (in which case, if such 
Indemnified Party notifies the Indemnifying Party in writing that it elects to 
employ separate counsel at the expense of the Indemnifying Party, the 
<PAGE>
 
Indemnifying Party shall not have the right to assume the defense thereof and 
such counsel shall be at the expense of the Indemnifying Party).  The 
Indemnifying Party shall not be liable for any settlement of any such 
Proceeding effected without its written consent, which consent shall not be 
unreasonably withheld.  No Indemnifying Party shall, without the prior written 
consent of the Indemnified Party, effect any settlement of any pending 
Proceeding in respect of which any Indemnified Party is a party, unless such 
settlement includes an unconditional release of such Indemnified Party from 
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable 
fees and expenses to the extent incurred in connection with investigating or 
preparing to defend such Proceeding in a manner not inconsistent with this 
Section) shall be paid to the Indemnified Party, as incurred, within 10 
Business Days of written notice thereof to the Indemnifying Party (regardless 
of whether it is ultimately determined that an Indemnified Party is not 
entitled to indemnification hereunder; provided, that the Indemnifying Party 
may require such Indemnified Party to undertake to reimburse all such fees and 
expenses to the extent it is finally judicially determined that such 
Indemnified Party is not entitled to indemnification hereunder).

          (d)     Contribution.  If a claim for indemnification under Section 
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or 
refusal of a governmental authority to enforce such indemnification in 
accordance with its terms (by reason of public policy or otherwise), then each 
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall 
contribute to the amount paid or payable by such Indemnified Party as a result 
of such Losses, in such proportion as is appropriate to reflect the relative 
fault of the Indemnifying Party and Indemnified Party in connection with the 
actions, statements or omissions that resulted in such Losses as well as any 
other relevant equitable considerations.  The relative fault of such 
Indemnifying Party and Indemnified Party shall be determined by reference to, 
among other things, whether any action in question, including any untrue or 
alleged untrue statement of a material fact or omission or alleged omission of 
a material fact, has been taken or made by, or relates to information supplied 
by, such Indemnifying Party or Indemnified Party, and the parties' relative 
intent, knowledge, access to information and opportunity to correct or prevent 
such action, statement or omission.  The amount paid or payable by a party as 
a result of any Losses shall be deemed to include, subject to the limitations 
set forth in Section 5(c), any reasonable attorneys' or other reasonable fees 
or expenses incurred by such party in connection with any Proceeding to the 
extent such party would have been indemnified for such fees or expenses if the 
indemnification provided for in this Section was available to such party in 
accordance with its terms.

          The parties hereto agree that it would not be just and equitable if 
contribution pursuant to this Section 5(d) were determined by pro rata 
allocation or by any other method of allocation that does not take into 
account the equitable considerations referred to in the immediately preceding 
paragraph.  Notwithstanding the provisions of this Section 5(d), the 
Purchasers shall not be required to contribute, in the aggregate, any amount 
in excess of the amount by which the proceeds actually received by the 
Purchasers from the sale of the Registrable Securities subject to the 
Proceeding exceeds the amount of any damages that the Purchasers have 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission.  No Person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any Person who was not guilty of such 
fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section 
are in addition to any liability that the Indemnifying Parties may have to the 
Indemnified Parties.

          6.     Other Company Registration Obligations; Piggy-Back 
Registration.

          (a)     No Inconsistent Agreements.  Except as and to the extent 
specifically set forth in Schedule 6(a) attached hereto, neither the Company 
nor any of its subsidiaries has, as of the date hereof, nor shall the Company 
or any of its subsidiaries, on or after the date of this Agreement, enter into 
any agreement with respect to its securities that is inconsistent with the 
rights granted to the Holders in this Agreement or otherwise conflicts with 
the provisions hereof.  Except as and to the extent specifically set forth in 
Schedule 6(a) attached hereto, neither the Company nor any of its subsidiaries 
has previously entered into any agreement granting any registration rights 
with respect to any of its securities to any Person.  Without limiting the 
generality of the foregoing, without the written consent of the Holders of a 
majority of the then outstanding Registrable Securities, the Company shall not 
grant to any Person the right to request the Company to register any 
securities of the Company under the Securities Act unless the rights so 
granted are subject in all respects to the prior rights in full of the Holders 
set forth herein, and are not otherwise in conflict or inconsistent with the 
provisions of this Agreement.

          (b)     No Piggyback on Registrations.  Except as and to the extent 
specifically set forth in Schedule 6(a) attached hereto, neither the Company 
nor any of its security holders (other than the Holders in such capacity 
pursuant hereto) may include securities of the Company in the Registration 
Statement other than the Registrable Securities, and the Company shall not 
enter into any agreement providing any such right to any of its 
securityholders.

          (c)     Piggy-Back Registrations.  If at any time during the 
Effectiveness Period there is not an effective Registration Statement covering 
all of the Registrable Securities and the Company shall determine to prepare 
and file with the Commission a registration statement relating to an offering 
for its own account or the account of others under the Securities Act of any 
of its equity securities, other than on Form S-4 or Form S-8 (each as 
promulgated under the Securities Act) or their then equivalents relating to 
equity securities to be issued solely in connection with any acquisition of 
any entity or business or equity securities issuable in connection with stock 
option or other employee benefit plans, then the Company shall send to each 
holder of Registrable Securities written notice of such determination and, if 
within twenty (20) days after receipt of such notice, any such holder shall so 
request in writing, the Company shall include in such registration statement 
all or any part of the Registrable Securities such holder requests to be 
registered.  No right to registration of Registrable Securities under this 
Section shall be construed to limit any registration otherwise required 
hereunder.

     7.     Miscellaneous

          (a)     Remedies.  In the event of a breach by the Company or by a 
Holder, of any of their obligations under this Agreement, each Holder or the 
Company, as the case may be, in addition to being entitled to exercise all 
rights granted by law and under this Agreement, including recovery of damages, 
will be entitled to specific performance of its rights under this Agreement.  
The Company and each Holder agree that monetary damages would not provide 
adequate compensation for any losses incurred by reason of a breach by it of 
any of the provisions of this Agreement and hereby further agrees that, in the 
event of any action for specific performance in respect of such breach, it 
shall waive the defense that a remedy at law would be adequate.

          (b)     Amendments and Waivers.  The provisions of this Agreement, 
<PAGE>
 
including the provisions of this sentence, may not be amended, modified or 
supplemented, and waivers or consents to departures from the provisions hereof 
may not be given, unless the same shall be in writing and signed by the 
Company and the Holders of at least 80% of the then outstanding Registrable 
Securities; provided, however, that, for the purposes of this sentence, 
Registrable Securities that are owned, directly or indirectly, by the Company, 
or an Affiliate of the Company are not deemed outstanding.  Notwithstanding 
the foregoing, a waiver or consent to depart from the provisions hereof with 
respect to a matter that relates exclusively to the rights of Holders and that 
does not directly or indirectly affect the rights of other Holders may be 
given by Holders of at least a majority of the Registrable Securities to which 
such waiver or consent relates; provided, however, that the provisions of this 
sentence may not be amended, modified, or supplemented except in accordance 
with the provisions of the immediately preceding sentence.

          (c)     Notices.  Any and all notices or other communications or 
deliveries required or permitted to be provided hereunder shall be in writing 
and shall be deemed given and effective on the earliest of (i) the date of 
transmission, if such notice or communication is delivered via facsimile at 
the facsimile telephone number specified in this Section prior to 5:00 p.m. 
(Salt Lake City time) on a Business Day, (ii) the Business Day after the date 
of transmission, if such notice or communication is delivered via facsimile at 
the facsimile telephone number specified in the Purchase Agreement later than 
5:00 p.m. (Salt Lake City time) on any date and earlier than 11:59 p.m. (Salt 
Lake City time) on such date, (iii) the Business Day following the date of 
mailing, if sent by nationally recognized overnight courier service, or (iv)

          (d)     Successors and Assigns.  This Agreement shall inure to the 
benefit of and be binding upon the successors and permitted assigns of each of 
the parties and shall inure to the benefit of each Holder.  The Company may

subsequent) successors and assigns.

          (f)     Counterparts.  This Agreement may be executed in any number 
of counterparts, each of which when so executed shall be deemed to be an 
original and, all of which taken together shall constitute one and the same 
Agreement.  In the event that any signature is delivered by facsimile 
transmission, such signature shall create a valid binding obligation of the 
party executing (or on whose behalf such signature is executed) the same with

provisions, covenants and restrictions set forth herein shall remain in full 
force and effect and shall in no way be affected, impaired or invalidated, and 
the parties hereto shall use their reasonable efforts to find and employ an 
alternative means to achieve the same or substantially the same result as that 
contemplated by such term, provision, covenant or restriction.  It is hereby 
stipulated and declared to be the intention of the parties that they would

void or unenforceable.

Securities is required hereunder, Registrable Securities held by the Company 
or its Affiliates (other than the Purchasers or transferees or successors or 
assigns thereof if such Persons are deemed to be Affiliates solely by reason 
of their holdings of such Registrable Securities) shall not be counted in 
determining whether such consent or approval was given by the Holders of such 
required percentage.

                         Other Registration Rights

1. Siemens Aktiengesellschaft.  On November 17, 1997, the Company entered into
a strategic collaborative agreement (the "Master Agreement") with Siemens 
Semiconductor Group of Siemens Aktiengesellschaft ("Siemens") pursuant to 
which the Company and Siemens will jointly pursue the development and 
commercialization of products incorporating the Company's technologies into 
Siemens integrated circuits ("ICs") for use in telecommunications products. 
The Master Agreement anticipates multiple product-specific collaborative 
efforts between the Company and Siemens for a variety of telecommunications 
applications as described in multiple to-be-negotiated sub-agreements 
("Statements of Work").

On February 11, 1998, the Company and Siemens executed the first Statement of 
Work pursuant to the Master Agreement.  In connection with the execution of 
the Statement of Work, and as anticipated by the Master Agreement, on February 
13, 1998, Siemens paid to the Company a total of 5,000,000 deutsche marks 
("DM").  Of that amount, 600,000 DM  was paid as the purchase price for 
warrants ("Warrants") to purchase up to 1,000,000 shares of fonix restricted 
common stock on or before the following dates and at the following exercise 
prices:

     No. of Shares     Exercise Price      Expiration Date

     200,000           U.S. $10.00         December 31, 1998
     200,000           U.S. $15.00         March 31, 1999
     200,000           U.S. $20.00         June 30, 1999
     200,000           U.S. $25.00         September 30, 1999
     200,000           U.S. $30.00         December 31, 1999

Further, 2,000,000 DM was paid to acquire shares of the Company's restricted 
Common Stock at any time prior to March 12, 1998.  If Siemens elects not to 
acquire all or a part of the Shares on or prior to March 12, 1998, the 
2,000,000 DM (or any lesser portion thereof not used to purchase the Common 
Stock) shall be accounted for as an additional advance royalty payment.  The 
purchase price of the Common Stock, if Siemens elects to purchase, shall be 
the closing price of Common Stock as quoted by the Nasdaq SmallCap Market on 
the day preceding the day on which Siemens notifies the Company of its 
election to purchase the Common Stock.

The Common Stock, if any, issued to Siemens as a result either of Siemens 
purchase of Common Stock or its exercise of the Warrants will be restricted 
stock.  The Company has agreed to register such shares of Common Stock within 
30 days of the earlier of (i) the exercise by Siemens of Warrants to purchase 
the first 200,000 shares of stock underlying the Warrants, or (ii) April 23, 
1998.  Siemens also has "piggyback" registration rights with respect to the 
Shares and the common stock underlying the Warrants.

2. Synergetics, Inc..  Synergetics, Inc., is a Utah corporation that entered
into a Product Development and Assignment Agreement (the "Development 
Agreement") with Phonic Technologies, Inc., a Utah corporation and the 
Company's predecessor in interest ("PTI") on October 16, 1993.  Under the 
Development Agreement, Synergetics agreed to perform research and development 
activities in connection with the development and commercialization of the 
Company's voice recognition technologies and to irrevocably transfer and 
assign to PTI any and all right, title and interest in and to the technology, 
in return for which PTI agreed to fund the research and development activities 
of Synergetics on an as-needed basis and to pay to Synergetics a royalty of 
10% of net sales of any products incorporating the technology or from any
