ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On July 31, 1998, fonix corporation, a Delaware corporation, (the "Company"
or "fonix") entered into an Agreement and Plan of Merger (the "Merger
Agreement") by and among fonix, ASI Acquisition Corporation, a Utah corporation
and wholly-owned subsidiary of fonix ("AAC"), and Articulate Systems, Inc., a
Delaware corporation with its principal place of business in Woburn,
Massachusetts ("Articulate").  Pursuant to the Merger Agreement, Articulate
would be merged (the "Merger") with and into AAC, with AAC being the surviving
entity.  Prior to the Merger, there was no material relationship between fonix
and any of its affiliates, directors or executive officers, on the one hand, and
Articulate or any of its affiliates, directors or executive officers, on the
other hand.  The Merger was unanimously approved and recommended to their
respective stockholders by the boards of directors of AAC and Articulate, and
was approved by the affirmative vote of a majority of the stockholders of both
Articulate and AAC, as required by the law of the states of Delaware and Utah,
respectively.  The Merger was also approved by the board of directors of fonix.
The transactions contemplated by the Merger Agreement were consummated on
September 2, 1998 (the "Closing"), as is described below. At the Closing, the
parties to the Merger Agreement entered into an Amendment No. 1 to Agreement and
Plan of Merger, dated as of September 2, 1998 (the "Amendment No. 1").

     Background of the Merger

     Articulate is engaged in the development of enterprise level, integrated
clinical reporting systems for vertical market opportunities. Articulate's
current market focus is providing solutions for healthcare organizations for
cost effective and rapid capture, transcription and management of dictated
clinical information across a network. Specifically, Articulate develops,
markets and supports through various strategic alliances an integrated
dictation/transcription solutions process called PowerScribe(R), to healthcare
organizations utilizing advanced continuous speech recognition technology to
significantly automate medical reporting. The PowerScribe(R) system is intended
to be user friendly to physicians and other medical professionals, to
significantly reduce transcription costs and report turnaround time, and to
provide other key benefits without sacrificing dictation accuracy or physician
acceptance. PowerScribe(R) for Radiology, Articulate's first product, began
shipping in September 1997. Articulate is in the process of developing a suite
of solutions for the healthcare and other markets.

     fonix, since 1994, has been engaged in research and development of certain
proprietary automatic computer voice recognition and related technologies
(collectively the "Core Technologies"). fonix believes that the Merger presents
an opportunity for fonix to diversify its operations and offer voice recognition
products that are complementary to its existing Core Technologies. fonix
believes that its entry into the $6 billion medical transcription industry with
Articulate's PowerScribe(R) and future voice driven medical products will allow
the Company to become a leader in that market. There can be no assurance,
however, that significant marketing opportunities will accrue to fonix as a
result of the Merger.

                                       2

     Terms of the Merger

     The Merger Agreement provided that, after the consummation of the Merger,
AAC would continue the business of Articulate as a wholly-owned subsidiary of
fonix. Pursuant to the Merger, AAC is to acquire all of the assets and assume
all of the liabilities of Articulate. Upon the filing of a certificate of merger
with the Secretary of State of Delaware and articles of merger with the Utah
Department of Commerce (the "Effective Date"), which occurred on September 2,
1998, the separate corporate existence of Articulate ceased. AAC will continue
the operations of Articulate after the consummation of the Merger under AAC's
Articles of Incorporation and Bylaws. The Merger Agreement provides that the
directors and officers of Articulate each resign their positions immediately
before the Effective Date in favor of the directors and officers of AAC. The
principal executive offices of AAC from and after the Effective Date will be 600
West Cummings Park, Suite 4500, Woburn, Massachusetts 01801, and its telephone
number is (781) 935-5656.

     Consideration

     Pursuant to the Merger Agreement, as consideration for fonix's acquisition
by merger of Articulate, fonix has tendered or will tender to the stockholders
of Articulate, in the aggregate, (i) 3,155,751 shares of the restricted common
stock of fonix ("Merger Shares"), and (ii) cash payment ("Cash Payment") of
$12,534,588 (the Merger Shares and the Cash Payment are referred to collectively
herein as the "Merger Consideration"). At Closing, 13 of the Articulate
stockholders agreed to accept a portion of the Cash Payment payable to them in
the form of demand notes bearing interest at the rate of 8.5% per annum, payable
at any time after November 1, 1998. The aggregate principal amount of such notes
is $4,747,339. Additionally, the Company agreed to pay seven Articulate
employees cash bonuses in the aggregate amount of $857,000. At Closing, the
Company delivered demand notes representing $452,900 of that aggregate bonus
amount. The balance is payable on or before January 31, 1999. The method of
calculating the Merger Consideration was as follows:

     At Closing, each share of capital stock of Articulate (including common
stock, Series A, B, C and D Preferred Stock, and common stock underlying
unexercised stock options) outstanding immediately prior to Closing was
exchanged for the right to receive 1.1422 Merger Shares and Cash Payment in the
amount of $ 4.5266.  

     Pursuant to the Amendment No. 1, in addition to the Merger Consideration,
the holder of each share of Articulate capital stock will be entitled to receive
 .7057 shares of additional fonix common stock ("Additional Shares").  The
Additional Shares will be issued to an escrow agent pending the approval of the
stockholders of fonix of the creation of a new class of non-voting common stock
to be issued in lieu thereof on a pro rata basis to all Articulate stockholders
(as described in Exhibit "A" to Amendment No. 1).  If such shareholder approval
is not obtained within the time specified in the Amendment No. 1, the Additional
Shares will be distributed to the Articulate capital stockholders, pro rata.

     The total purchase price for the Merger (including the Merger Shares, the
Cash Payment and the Additional Shares) was determined pursuant to arms-length
negotiations between fonix and Articulate.

                                       3
<PAGE>
 
     After the merger, the former shareholders of Articulate, constituting 62
persons, beneficially own 8.8% of the total 58,586,633 shares of fonix common
stock issued and outstanding as of the date hereof.

     Prior to the Effective Date, Articulate's principal place of business was
Woburn, Massachusetts, and its principal executive offices were located at 600
West Cummings Park, Suite 4500, Woburn, Massachusetts 01801. At that address,
Articulate occupied approximately 9,600 square feet of office space, which is
leased subject to a 15-month lease. Pursuant to the Merger, fonix, through AAC,
has agreed to assume that lease and will continue the business operations of
Articulate at that location, although the principal executive offices of the
Company and AAC will be located in Draper, Utah, at fonix's corporate
headquarters.

     Prior to the Merger, Articulate owned or leased the equipment used in its
business.  After the Merger, AAC intends to continue to use the same equipment
(whether owned or leased by Articulate) for the same business as was conducted
by Articulate prior to the Merger.

     The Cash Payment component of the Merger Consideration paid to date was
obtained by fonix pursuant to a private placement of its preferred stock
that was consummated as of August 31, 1998. (See Item 5., below.)

     Additional Terms

     Pursuant to an Escrow Agreement executed on September 2, 1998, fonix and
Articulate agreed to place 315,575 Merger Shares in escrow as the sole recourse
of fonix in the event of any breach by Articulate of the representations and
warranties included in the Merger Agreement. The term of the escrow arrangement
is one year, after the expiration of which, the shares deposited into escrow,
less any amount deemed to be payment to fonix for damages suffered as a result
of any breach by Articulate, are to be remitted, pro-rata, to the Articulate
shareholders in proportion to the percentage of Articulate common stock owned by
them prior to the consummation of the Merger.

Item 5.  Other Information

     March 1998 Private Placement of Common Stock
     --------------------------------------------

     On March 12, 1998, the Company completed a private placement (the "March
1998 Offering") of up to 6,666,666 shares of its restricted common stock to
seven accredited investors.  The total purchase price to be paid by the
investors pursuant to the March 1998 Offering was $30,000,000.  Of that amount,
$15,000,000 was received by the Company on March 12, 1998, in return for which
the Company issued a total of 3,333,333 shares of restricted common stock.
Finders' fees of $870,000 were paid in connection with the $15,000,000 received.
The remainder of the purchase price was to be paid by the investors on July 27,
1998 (60 days after the effectiveness of a registration statement that the
Company filed with the Securities and Exchange Commission covering the common
stock issued and issuable to the investors) (the "Second Funding Date"),
provided that, as of such date, certain conditions were satisfied.

     Additionally, the investors in the March 1998 Offering had certain "reset"
rights pursuant to which the investors would receive additional shares of


                                       4
<PAGE>
 
restricted common stock ("Reset Shares") if the average market price of the
Company's common stock for the 60-day periods following the initial closing date
and the Second Funding Date did not equal or exceed $5.40 per share.

     In June and August 1998, some of the investors in the March 1998 Offering
provided $3,000,000 in additional funding ("Supplemental Funding") in exchange
for which the Company issued a total of 666,666 shares of common stock subject
to the terms and conditions of the March 1998 Offering documents (including the
Reset Share provisions). The Company did not thereafter receive and does not
anticipate receiving in the future any other funding pursuant to the March 1998
Offering.

     August 31, 1998 Private Placement of Series D Preferred Stock
     -------------------------------------------------------------

     On August 31, 1998, the Company commenced a private placement (the
"Preferred Offering") of up to $12,000,000 of its Series D 4% Convertible
Preferred Stock ("Series D") to approximately eight accredited institutional
investors. In connection with the Preferred Offering, as of August 31, 1998, the
Company received $10,000,000 in new funding, in return for which it issued
500,000 shares of Series D to four accredited investors. Additionally, the
Company entered into an agreement with the investors who participated in the
March 1998 Offering to issue a total of 608,333 shares of Series D in return for
those investors' agreement to terminate the Company's obligations with respect
to issuing Reset Shares in respect of the 3,333,333 shares of common stock
issued to them in March 1998. However, in respect of the 666,666 shares of
common stock issued to several of those investors as a result of their
advancement of the Supplemental Funding, notwithstanding the failure of certain
conditions as of the Second Funding Date, the Company agreed to issue a total of
1,390,476 Reset Shares. In light of the agreement set forth in the Preferred
Offering, the Company has no further obligations to issue any securities under
the terms of the March 1998 Offering.

     2.4  Effect of Merger.
          ---------------- 

          (a) General. The Merger shall become effective at the time (the
              -------                                                    
"Effective Time") Merger Sub and Target file the Certificate of Merger with the
Secretary of State of the State of Delaware and the Utah Department of Commerce,
Division of Corporations and Commercial Code.  The Merger shall have the effect
set forth in the Delaware General Corporation Law and the Utah Business
Corporation Act.  The Surviving Corporation may, at any time after the Effective
Time, take any action (including executing and delivering any document) in the
name and on behalf of either Merger Sub or Target in order to carry out and
effectuate the transactions contemplated by this Agreement.

          (b) Articles of Incorporation.  The Articles of Incorporation of
              -------------------------                                   
Merger Sub in effect at and as of the Effective Time will remain the Articles of
Incorporation of the Surviving Corporation without any modification or amendment
in the Merger.

          (c) Bylaws.  The Bylaws of Merger Sub in effect at and as of the
              ------                                                      
Effective Time will remain the Bylaws of the Surviving Corporation without any
modification or amendment in the Merger.

          (d) Directors and Officers.  The directors and officers of Merger Sub
              ----------------------                                           
in office at and as of the Effective Time will remain the directors and officers
of the Surviving Corporation (retaining their respective positions and terms of
office).

          (e) Conversion of Target Shares.  At and as of the Effective Time, and
              ---------------------------                                       
without any further action by any of the Target Stockholders, subject to Section
2.4(f), each outstanding Target Share shall be converted into the right to
receive: (i) that number of validly issued, fully paid and nonassessable
unregistered Buyer Shares ("Merger Shares"), which equals the amount obtained by
dividing (A) the quotient of (a) $11,800,000 divided by (b) the Closing Price,
by (B) 2,916,093 (the "Exchange Ratio"); and (ii) cash in the amount of
$13,200,000 divided by 2,916,093 (the "Cash Payment").  "Closing Price" shall
mean the average of (1) $5.0250; (2) $3.4219, and (3) the average closing "bid"
price of a Buyer Share as reported on the Nasdaq SmallCap Market for the ten
(10) trading days immediately prior to the fifth (5/th/) business day
immediately prior to the Closing Date.  No Target Share shall be deemed to be
outstanding or to have any rights other than those set forth in this Section 2.4
after the Effective Time.

          (f) Regulation D Restrictions.  Notwithstanding Section 2.4(e), Buyer
              -------------------------                                        
shall not offer, sell, issue or deliver Merger Shares or Buyer Exchange Options
to any Target Stockholder or any holder of Target Options who Buyer does not
reasonably believe to be an "accredited investor" as that term is defined in
Regulation D ("Reg. D") promulgated under the Securities Act, or who 



                                       5
<PAGE>
 
Buyer does not reasonably believe has, either alone or with his or its purchaser
representative, such knowledge and experience in financial and business matters
that he or it is capable of evaluating the merits and risks of exchanging his or
its Target Shares or Target Options, as the case may be, for Merger Shares or
Buyer Exchange Options (each an "Unqualified Stockholder"). Additionally, Buyer
shall not offer, sell, issue or deliver Merger Shares or Buyer Exchange Shares
to more than 35 Target Stockholders or holders of Target Options who are not
accredited investors but who Buyer reasonably believes have, either alone or
with their purchaser representatives, such knowledge and experience in financial
and business matters that they are capable of evaluating the merits and risks of
exchanging their Target Shares for Merger Shares or their Target Options for
Buyer Exchange Options ("Sophisticated Stockholders"). If at Closing Buyer
determines there are any Unqualified Stockholders or more than 35 Sophisticated
Stockholders, Buyer shall, in addition to making the payments to accredited
investors pursuant to Section 2.4(e):

          (i) rank all Sophisticated Stockholders according to the extent of
their respective percentage ownership of Target Shares on a fully diluted basis,
and in accordance with Sections 2.4(e), 2.4(l) and 2.4(t), issue and deliver
Merger Shares, Cash Payments or Buyer Exchange Options to only the 35
Sophisticated Stockholders who own the largest percentages of the total number
of outstanding Target Shares on a fully diluted basis at Closing; and

          (ii) deliver, in accordance with Section 2.4(l), to each Sophisticated
Stockholder who is entitled to but does not receive payment under Section
2.4(f)(i) and to all Unqualified Stockholders the following consideration: (1)
the Cash Payment, and (2) additional cash consideration in an amount that shall
be determined by multiplying (a) the number of Merger Shares such Target
Stockholders otherwise would be eligible to receive by (b) the Closing Price,
provided that if any such Sophisticated Stockholder or Unqualified Stockholder
shall own Target Options, the cash consideration payable hereunder shall be
limited to the present cash value of such Target Options, as shall be determined
in good faith by Buyer according to a generally accepted valuation formula.

          (g) Capital Stock of Merger Sub.  At the Effective Time, each share of
              ---------------------------                                       
common stock of Merger Sub ("Merger Sub Common Stock") issued and outstanding
immediately prior to the Effective Time shall be converted into and exchanged
for one validly issued, fully paid and nonassessable share of common stock of
the Surviving Corporation.  Each stock certificate of Merger Sub evidencing
ownership of any such shares shall continue to evidence ownership of such shares
of capital stock of the Surviving Corporation.

          (h) Adjustments to Exchange Ratio.  The Exchange Ratio shall be
              -----------------------------                              
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Buyer Shares or Target Shares), reorganization, recapitalization or other like
change with respect to Buyer Shares or Target Shares occurring after the date
hereof and prior to the Effective Time.

          (i) Fractional Shares.  No fraction of a Merger Share will be issued,
              -----------------                                                
but in lieu thereof, and to the extent not waived in writing, each holder of
Target Shares who otherwise would be entitled to a fraction of a Merger Share
(after aggregating all fractional Merger Shares to be 



                                       6
<PAGE>
 
received by such person) shall receive from Buyer an amount of cash (rounded to
the nearest whole cent) equal to the product of (i) such fraction, multiplied by
(ii) the Closing Price. The fractional share interests of each Target
Stockholder shall be aggregated, so that no Target Stockholder shall receive
cash in respect of fractional share interests in an amount greater than the
value of one full Merger Share.

          (j) Dissenters' Rights.  Dissenting Target Shares ("Dissenting
              ------------------                                        
Shares"), if any, shall not be converted into the Merger Consideration but shall
instead be converted into the right to receive such consideration as may be
determined to be due with respect to such Dissenting Shares pursuant to the
Delaware General Corporation Law.  Target shall give Buyer prompt notice of any
demand received by Target to require Target to purchase shares of outstanding
Target Shares, and Buyer shall have the right to direct and participate in all
negotiations and proceedings with respect to such demand.  Target agrees that,
except with the prior written consent of Buyer, or as required under the
Delaware General Corporation Law, it will not voluntarily make any payment with
respect to, or settle or offer to settle, any such purchase demand.  Each holder
of Dissenting Shares ("Dissenting Stockholder") who, pursuant to the provisions
of the Delaware General Corporation Law, becomes entitled to payment of the fair
value for Dissenting Shares shall receive payment therefor (but only after the
value therefor shall have been agreed upon or finally determined pursuant to
such provisions).  If, after the Effective Time, any Dissenting Shares shall
lose their status as Dissenting Shares, Buyer shall issue and deliver, upon
surrender by such Dissenting Stockholder of a certificate or certificates
representing shares of Target Shares, the Merger Consideration to which such
Target Stockholder would otherwise be entitled under this Section 2.4 and the
Certificate of Merger less the Merger Consideration allocable to such Target
Stockholder that has been deposited in the Escrow Fund (as defined below) in
respect of such Target Shares pursuant to Article 7.

          (k) Certificate Legends.  When issued as contemplated by this
              -------------------                                      
Agreement, the Merger Shares shall not have been registered and shall be
characterized as "restricted securities" under the federal securities laws, and
under such laws such shares may be resold without registration under the
Securities Act, only in certain limited circumstances.  Each certificate
evidencing Merger Shares shall bear a legend in substantially the following
form:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED (THE "ACT"). SUCH SHARES MAY NOT BE SOLD OR OTHERWISE
     TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION WITHOUT AN EXEMPTION UNDER
     THE ACT OR AN OPINION OF LEGAL COUNSEL REASONABLY ACCEPTABLE TO BUYER THAT
     SUCH REGISTRATION IS NOT REQUIRED."

and any additional legends required by state securities laws.  Buyer will cause
any such legend to be removed from the certificate or certificates representing
the Merger Shares upon receipt from the holder thereof of an opinion of counsel
to the effect that the Merger Shares represented by such certificate may be
resold pursuant to Commission Rule 144(k).

      (l) Procedure for Payment.
          --------------------- 

          (i)   At Closing, Buyer will deliver to Durham, Evans, Jones &
Pinegar, P.C. (the "Exchange Agent") (A) stock certificates (issued in the names
of the Target Stockholders or their nominees) representing that number of whole
Merger Shares issuable to the Target Stockholders equal to the product of (I)
the Exchange Ratio times (II) the number of outstanding Target Shares held of
record by each Target Stockholder, less the number of Merger Shares to be
deposited in the Escrow Fund on such holder's behalf pursuant to Article 7
hereof, and subject to any adjustment in such number resulting from Section
2.4(f), and (B) checks representing presently available funds payable to the
Target Stockholders in amounts equal to the sum of (1) cash (without interest)
in the amount of the Cash Payment which such holder has the right to receive in
accordance with Section 2.4(e) in respect of the Target Shares formerly
evidenced by such tendered certificate, (2) any dividends or other distributions
to which such holder is entitled pursuant to Section 2.4(m), (3) cash (without
interest) in respect of fractional shares as provided in Section 2.4(i), and (4)
any additional cash payment payable to any Unqualified Stockholder or
Sophisticated Stockholder pursuant to Section 2.4(f) (collectively such Merger
Shares and cash consideration, "Merger Consideration").

          (ii)  Buyer shall cause the Exchange Agent to mail a letter of
transmittal (with instructions for its use) in the form attached hereto as
Exhibit B, together with such other customary documents as may be required
pursuant to such instructions, including without limitation, a Form W-9 or W-8
to each record holder of outstanding Target Shares for the holder to use in
surrendering the certificates which represent his or its Target Shares in
exchange for the Merger Consideration payable to such holder.

          (iii) Upon surrender to the Exchange Agent of a Target Certificate
for cancellation, together with such letter of transmittal and other documents,
duly completed and validly executed in accordance with the instructions thereto,
the holder of such Target Shares shall be entitled to receive in exchange
therefor the Merger Consideration payable to such Holder.  Upon delivery of such
payment to the Target Stockholder, the Target Certificate so surrendered shall
forthwith be canceled.  Until so surrendered, each outstanding Target
Certificate that, prior to the Effective Time, represented Target Shares will be
deemed from and after the Effective Time, for all corporate purposes, other than
the payment of dividends, which shall be paid in full upon surrender of such
Target Certificate or affidavit of lost certificate as described below, to
evidence the ownership of the number of full Merger Shares and the cash
consideration described in this Section 2.4(l)(iii).

          (iv)  If any Target Certificates shall have been lost, stolen or
destroyed, Buyer shall cause to be issued in exchange for such lost, stolen or
destroyed Target Certificates, upon the making of an affidavit of that fact by
the holder thereof in form acceptable to Buyer, such Merger Consideration as may
be required pursuant to this Section 2.4; provided, however, that any such
affidavit shall include a covenant by such Target Stockholder indemnifying Buyer
for any claim that may be made against Buyer, the Surviving Corporation or the
Exchange Agent with respect to the Target Certificates alleged to have been
lost, stolen or destroyed.



                                       8
<PAGE>
 
          (v)   Any portion of the Merger Consideration delivered to the
Exchange Agent which remains undistributed to the Target Stockholders one
hundred eighty (180)days after the Effective Time shall be delivered to Buyer,
upon demand, and any Target Stockholders who have not previously complied with
this Section 2.4 shall thereafter look only to Buyer for payment of their claim
for the Merger Consideration.

          (vi)  Notwithstanding anything to the contrary in this Agreement,
none of the Exchange Agent, the Surviving Corporation or any party hereto shall
be liable to any person for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

          (vii) Buyer shall pay all charges and expenses of the Exchange
Agent.

          (m)   Distributions on Merger Shares.  Buyer will not pay any dividend
                ------------------------------                                  
or make any distribution on Merger Shares (with a record date at or after the
Effective Time) to any record holder of outstanding Target Shares until the
holder surrenders for exchange his or its certificates which represented Target
Shares. Buyer instead will pay the dividend or make the distribution to the
Exchange Agent in trust for the benefit of the holder pending surrender and
exchange. In no event, however, will any holder of outstanding Target Shares be
entitled to any interest or earnings on the dividend or distribution pending
receipt.

          (n)   Transfers of Ownership.  At the Effective Time, the stock 
                ----------------------
transfer books of Target shall be closed and there shall be no further
registration of transfers of capital stock of Target thereafter on the records
of Target. If any certificate for Merger Shares is to be issued in a name other
than in which the Target Certificate surrendered in exchange therefor is
registered, it will be a condition of the issuance thereof that the Target
Certificate so surrendered will be properly endorsed and otherwise in proper
form for transfer (or that an affidavit of lost, stolen or destroyed certificate
as required in Section 2.4(l) shall be provided in lieu of such Target
Certificate) and that the person requesting such exchange will have paid to
Buyer or any agent designated by it any transfer or other taxes required by
reason of the issuance of a certificate for Merger Shares in any name other than
that of the registered holder of the Target Certificate surrendered, or
established to the satisfaction of Buyer or any agent designated by it that such
tax has been paid or is not payable.

          (o)   Dissenting Shares.  The provisions of this Section 2.4 shall 
                -----------------
also apply to Dissenting Shares that lose their status as such, except that the
obligations of Buyer under this Section 2.4 shall commence on the date of loss
of such status and the holder of such shares shall be entitled to receive in
exchange for such shares the Merger Consideration to which such holder is
entitled pursuant to Section 2.4(e).

          (p)   Escrow.  At Closing, and subject to and in accordance with the
                ------                                                        
provisions of Article 7, Buyer shall cause to be distributed to the Escrow Agent
(as defined in Section 7.1 hereof) a certificate or certificates representing
the Escrow Shares (which shall be registered in the name of the Escrow Agent).
Such shares shall be beneficially owned, pro rata by the Target Stockholders who
receive Merger Consideration, and such shares shall be held in escrow and shall
be available to 



                                       9
<PAGE>
 
compensate Buyer for certain damages as provided in Article 7. To the extent not
used for such purposes, such shares shall be released, all as provided in
Article 7.

          (q)   No Further Ownership Rights in Target Shares.  The Merger
                --------------------------------------------             
Consideration delivered upon the surrender for exchange of Target Shares in
accordance with the terms hereof (including any dividends, distributions or cash
paid in lieu of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Target Shares, and there shall be
no further registration of transfers on the records of the Surviving Corporation
of Target Shares which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Target Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Section 2.4.

          (r)   Tax Consequences.  It is intended by the parties hereto that the
                ----------------                                                
Merger shall constitute a tax-free reorganization within the meaning of Section
368(a)(2)(D) of the Code.

          (s)   Taking of Necessary Action; Further Action.  Each of Buyer, 
                ------------------------------------------        
Target and Merger Sub will take all such reasonable and lawful action as may be
necessary or desirable in order to effectuate the Merger in accordance with this
Agreement as promptly as possible.  If, at any time after the Effective Time,
any further action is necessary or desirable to carry out the purposes of this
Agreement and to vest the Surviving Corporation with full right, title and
possession to all assets, property, rights, privileges, powers and franchises of
Target and Merger Sub, the officers and directors of Target and Merger Sub are
fully authorized in the name of their respective corporations or otherwise to
take, and will take, all such lawful and necessary action, so long as such
action is not inconsistent with this Agreement.
 
          (t)   Conversion of Outstanding Target Options.  At the Effective 
                ----------------------------------------       
Time, Buyer shall assume each unexpired and unexercised option of Target,
whether vested or unvested, that is in effect at the Effective Time (each, a
"Target Option") and each such Target Option shall be automatically converted at
the Effective Time into an option (a "Buyer Exchange Option") to purchase that
number of shares of Buyer Shares equal to the number of Target Shares issuable
immediately prior to the Effective Time upon exercise of the Target Option
(without regard to actual restrictions on exercisability) multiplied by a
fraction, the numerator of which is $25,000,000 and the denominator of which is
the product of (x) 2,916,093 and (y) the Closing Price, with an exercise price
equal to the exercise price that existed under the corresponding Target Option
multiplied by a fraction, the numerator of which is the product of (x) 2,916,093
and (y) the Closing Price and the denominator of which is $25,000,000, and with
other terms and conditions that are the same as the terms and conditions of such
Target Option immediately before the Effective Time, including without
limitation, term, exercisability, vesting schedule, to the extent reasonably and
legally possible, in Buyer's discretion after consultation with its tax counsel,
status as an "incentive stock option" under Section 422 of the Code and
acceleration and termination provisions; provided that with respect to any
Target Option that is an "incentive stock option" within the meaning of Section
422 of the Code, the foregoing conversion shall be carried out in a manner
satisfying the requirements of Section 424(a) of the Code if possible. In
connection with the issuance of Buyer Exchange Options, Buyer shall (i) reserve
for issuance the number of Buyer Shares that will become subject to Buyer
Exchange Options pursuant to this Section 2.4(t) and (ii) from and after the
Effec-

                                       10
<PAGE>
 
tive Time, upon exercise of Buyer Exchange Options, make available for
issuance all Buyer Shares covered thereby, subject to the terms and conditions
applicable thereto.  Employment with Target shall be credited to holders of
Buyer Exchange Options for purposes of determining the number of vested Buyer
Shares subject to exercise under Buyer Exchange Options after the Effective
Time.  As soon as practicable after the Effective Time, but no later than thirty
(30) days thereafter, Buyer shall deliver to the holders of Buyer Exchange
Options appropriate notices informing such holders that such options have been
assumed by the Surviving Corporation and will constitute options to purchase
Buyer Shares on substantially the same terms and conditions as their Target
Options (subject to the adjustments required by this Section 2.4).


                                  ARTICLE 3.
                   REPRESENTATIONS AND WARRANTIES OF TARGET

     Target represents and warrants to Buyer and Merger Sub that the statements
contained in this Article 3 are correct and complete as of the date of this
Agreement and will be correct and complete in all material respects as of the
Closing Date (as though made then and as though the Closing Date were
substituted for the date of this Agreement throughout this Article 3), except as
set forth in the disclosure schedule of Target accompanying this Agreement and
initialed by the Parties (the "Target Disclosure Schedule").  The Target
Disclosure Schedule will be arranged and numbered in paragraphs corresponding to
the lettered and numbered paragraphs contained in this Article 3.

with full power and authority (corporate and other) to own, lease, use and
operate its properties and to conduct its business as and where now owned,
leased, used, operated and conducted.  Target is duly qualified to do business
and in good standing in each jurisdiction  in which the nature of the business
conducted by it  or the property it owns, leases or operates  makes
qualification necessary, except where the failure to be so qualified or in good
standing in such jurisdiction would not have a Material Adverse Effect on
Target.  Except as set forth in Section 3.1 to the Target Disclosure Schedule,
                                --------------------------------------------- 
Target is not in default in the performance, observance or fulfillment or
otherwise in violation of any provision of its Certificate of Incorporation, as

a complete and correct copy of the Target Certificate and the Target Bylaws.

     3.2  Subsidiaries.  Target does not own, directly or indirectly, any equity

or other ownership interest in any corporation, partnership, joint venture or
other entity or enterprise. Except as set forth in Section 3.2 to the Target
                                                   -------------------------

contribution or otherwise) in any  corporation, partnership, joint venture or
other entity or enterprise.

     3.3  Corporate Power and Authority.  Target has all requisite corporate
          -----------------------------

and adoption of the Merger and the transactions contemplated hereby by Target
Stockholders, to consummate the transactions 



                                       11

contemplated by this Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of Target, subject to
authorization and adoption of the Merger and the transactions contemplated
hereby by the Target Stockholders. The Board of Directors of Target has (i)
unanimously approved this Agreement and the Merger, (ii) determined that in its
opinion the Merger is in the best interests of the Target Stockholders and is on
terms that are fair to the Target Stockholders and (iii) recommended that the
Target Stockholders approve this Agreement and the Merger. This Agreement has
been duly executed and delivered by Target and constitutes the legal, valid and
binding obligation of Target, enforceable against Target in accordance with its
terms.

     3.4  Capitalization of Target.  As of the date hereof, Target's authorized
          ------------------------

filed or caused to be filed all Tax Returns required to be filed by it through
the date hereof and prior to the Closing Date shall have filed or caused to be
filed all Tax Returns required to be filed by it through the Closing Date. All
such Tax Returns that have been filed are true complete and correct. Neither the
IRS nor any other governmental entity is now auditing or asserting or, to the
knowledge of Target, threatening to assert against Target, any deficiency or
claim for additional Taxes. Target currently is not the beneficiary of any
extension of time within which to file any Tax Return. No claim has ever been
made by any authority in a jurisdiction where Target does not file Tax Returns
that it is or may be subject to taxation by that jurisdiction. To Target's
Knowledge, there are no Security Interests on any of the assets of any of Target
that arose in connection with any failure (or alleged failure) to pay any Tax.
Target has no Knowledge that any authority intends to assess any additional
Taxes for any period for which Tax Returns have been filed. Target has not
waived any statute of limitations in respect of Taxes or agreed to any extension
of time with respect to a Tax assessment or deficiency.

          (b)    Target has delivered to Buyer copies of material portions of
all federal income Tax Returns, examination reports, and statements of
deficiencies assessed against or agreed to by Target since January 1, 1994.

          (c)    Target is not obligated by any contract, agreement or other
arrangement to indemnify any other person with respect to Taxes.  Target is not
now nor ever has been a party to or bound by any tax sharing agreement or any
agreement or arrangement (whether or not written and including, without
limitation, any arrangement required or permitted by law) binding Target which
(i) requires Target to make any tax payment to or for the account of any other
person, (ii) affords any other person the benefit of any net operating loss, net
capital loss, investment tax credit, foreign tax credit, charitable deduction or
any other credit or tax attribute which could reduce Taxes (including, without
limitation, deductions and credits related to alternative minimum Taxes) of
Target, (iii) requires or permits the transfer or assignment of income,
revenues, receipts or gains to Target, from any other person, or (iv) otherwise
requires Target to indemnify any other person in respect of Taxes.

          (d)    Target has withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder or other third party.

          (e)    "Tax Returns" means returns, information returns, reports,
forms and other documents (including, any related or supporting information)
required to be filed with any governmental authority of the United States or any
other jurisdiction responsible for the imposition, administration or collection
of Taxes.

          (f)   "Taxes" means (i) all Taxes (whether federal, state, local or
foreign) based upon or measured by income and any other tax whatsoever,
including, without limitation, gross receipts, estimated, profits, sales, use,
occupation, value added, ad valorem, transfer, franchise, withholding, payroll,
employment, excise, or property Taxes, together with any interest or penalties,
additions to Taxes or additional amounts, imposed with respect thereto, (ii) any
liability for payments of amounts of Taxes described in  the immediately
preceding clause (i) as a result of being a "transferee" (within the meaning of
Section 6901 of the Code or any other applicable law) of another person,
successor or a member of any affiliated, consolidated or combined group and
(iii) any obligations under any agreements or arrangements with respect to any
Taxes described in clause (i) above.

                -----------------------------------

report, registration statement, definitive proxy statement, and other filing
filed with the SEC by Buyer since December 31, 1997, and, prior to the Effective
Time, Buyer will have furnished Target with true and correct copies of any
additional documents filed with the SEC by Buyer prior to the Effective Time
(collectively, the "Buyer SEC Documents").  In addition, Buyer has made
available to Target  all material exhibits to the Buyer SEC Documents filed
prior to the date hereof and will promptly make available to Target all material
exhibits to any additional Buyer SEC Documents filed prior to the Effective
Time.  All documents required to be filed as exhibits to the Buyer SEC Documents
have been so filed, and all material contracts so filed as exhibits are in full
force and effect except those which have expired in accordance with their terms,
and neither Buyer nor any of its subsidiaries is in default thereunder.  As of
their respective filing dates, the Buyer SEC Documents complied in all material
respects with the requirements of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the Securities Act and none of the Buyer SEC
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading, except to the extent corrected by a subsequently filed Buyer SEC
Document prior to the date hereof.  The financial statements of Buyer, including
the notes thereto, included in the Buyer SEC Documents (the "Buyer Financial
Statements"), complied as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of the SEC
with respect thereto as of their respective dates, and have been prepared in
accordance with GAAP applied on a basis consistent throughout the periods
indicated and consistent with each other (except as may be indicated in the
notes thereto or, in the case of unaudited statements included in Quarterly
Reports on Form 10-Q or Form 10-QSB, as permitted by Form 10-Q or Form 10-QSB of
the SEC).  The Buyer Financial Statements fairly present the consolidated
financial condition and operating results of Buyer and its subsidiaries at the
dates and during the periods indicated therein (subject, in the case of
unaudited statements, to normal, recurring year-end adjustments). There has been
no material change in Buyer's accounting policies except as described in the
notes to the Buyer Financial Statement.  Since December 31, 1997, no event has
occurred that would have required the filing of any report that otherwise would
have been included among the SEC Documents and for which an appropriate report
was not filed.

qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Shares requested by such Holder to be so
included in a written request or requests, made within twenty (20) days after
receipt of such written notice from Buyer, by any Holder.

        (c)   Underwriting.
              ------------ 

              (i)    If the registration of which Buyer gives notice is for a
     registered public offering involving an underwriting, Buyer shall so advise
     the Holders as a part of the written notice given pursuant to Section
     5.10(b).  In such event, the right of any Holder to registration pursuant
     to this Section 5.10 shall be conditioned upon such Holder's participation
     in such underwriting, and the inclusion of his or its Registrable Shares in
     the underwriting shall be limited to the extent provided herein.

              (ii)   All Holders proposing to distribute their securities
     through such underwriting shall (together with Buyer and the other Holders
     distributing their Registrable Shares through such underwriting) enter into
     an underwriting agreement in customary form with the managing underwriter
     selected for such underwriting by Buyer. Notwithstanding any other
     provision of this Section 5.10, if the managing underwriter determines that
     marketing factors require a limitation of the number of shares to be
     underwritten, then Buyer shall so advise all Holders of Registrable Shares
     and the holders of any other securities to be included in the registration
     pursuant to other piggyback registration rights, and the managing
     underwriter may limit the number of shares of Registrable Shares and other
     securities to be included pursuant to other piggyback rights that may be
     included in such registration to an amount no less than 25% of all shares
     to be included in such offering; provided however, that any such limitation
     or "cut back" shall first be applied to all shares proposed to be sold in
     such offering other than for the account of Buyer which are not Registrable
     Shares. Buyer shall so advise all Holders and other holders distributing
     their securities through such underwriting, and the number of shares of
     Registrable Shares or other securities that may be included in the
     registration and underwriting shall be first allocated among all Holders
     requesting inclusion of their Registrable Shares in the registration in
     proportion, as nearly as practicable, to the respective amounts of
     Registrable Shares requested to be included in such registration statement.
     No Registrable Shares or other securities excluded from the


                                       33
<PAGE>
 
     underwriting by reason of the managing underwriters' marketing limitation
     shall be included in such registration.

               (iii)  If any of the Holders disapprove of the terms of any such
     underwriting, such Holder may elect to withdraw therefrom by written notice
     to Buyer and the managing underwriter.  Any securities excluded or
     withdrawn from such underwriting shall be withdrawn from such registration.


          (d)  Right to Terminate Registration.  Buyer shall have the right to
               -------------------------------                                
terminate or withdraw any registration initiated by it under this Section  prior
to the effectiveness of such registration whether or not any Holder has elected
to include securities in such registration, provided that any registration
termination pursuant to this Section 5.10(d) shall have not adversely affect the
registration rights granted under this Section 5.10.
 
          (e)  Copies of Registration Statement and Prospectus.  Buyer shall
               -----------------------------------------------              
promptly deliver to each Holder, and any underwriters, without charge, a copy of
each registration statement filed with the Commission pursuant to this Section
5.10 (the "Registration Statement"), and as many copies of the prospectus or
prospectuses (including each form of prospectus) included in any such
Registration Statement and each amendment or supplement thereto as such persons
may reasonably request.
 
          (f)  Effectiveness Period.  Buyer shall use its best efforts to cause
               --------------------                                            
any Registration Statement to be declared effective under the Securities Act as
promptly as possible after the filing thereof, and shall use its best efforts to
keep such Registration Statement continuously effective under the Securities Act
until the date which is one year after the date that such Registration Statement
is declared effective by the Commission or such earlier date when all
Registrable Shares 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 Buyer pursuant to a written
opinion letter to such effect, addressed and acceptable to Buyer's transfer
agent (as to such Registration Statement, the "Effectiveness Period").
 
          (g)  Rule 144 Reporting.  With a view to making available the benefits
               ------------------                                               
of certain rules and regulations of the Commission which may at any time permit
the sale of the Merger Shares to the public without registration, Buyer shall
use commercially reasonable efforts to:
 
               (i)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the Closing Date and during the Effectiveness Period;

               (ii) File with the Commission in a timely manner all reports,
documents and other information required of Buyer under the Securities Act and
the Exchange Act at all times after the Closing Date and during the
Effectiveness Period; and

                                       34
<PAGE>
 
            (iii)    So long as any of the Holders owns any Merger Shares, to
furnish to such Holders forthwith upon request a written statement by Buyer as
to its compliance (or failure to comply) with the reporting requirements of said
Rule 144, and with the Securities Act and the Exchange Act, a copy of the most
recent annual or quarterly report of Buyer, and such other reports and documents
of Buyer and other information in the possession of or reasonably obtainable by
Buyer as such Holders may reasonably request in availing themselves of any rule
or regulation of the Commission allowing the Holders to sell any such securities
without registration.

      (h)   Limitations.  Notwithstanding the foregoing, Buyer shall not be 
            -----------
obligated to take any action pursuant to this Section 5.10:

            (i)      in any particular jurisdiction in which Buyer would be
required to execute a general consent to service of process in effecting such
registration, qualification or compliance, unless Buyer is already subject to
service in such jurisdiction and except as may be required by the Securities
Act; or

            (ii)     prior to six months after the Effective Time.

      (i)   Expenses.  The costs and expenses to be borne by Buyer for
            --------                                                  
purposes of this Section 5.10 shall include, without limitation, printing
expenses, legal fees and disbursements of counsel for Buyer, "blue sky"
expenses, accounting fees and filing fees, but shall not include underwriting
commissions or similar charges, legal fees and disbursements of counsel for the
selling Holders. All expenses of any registered offering not otherwise borne by
Buyer shall be borne pro rata among the selling Holders on the basis of the
number of shares registered.

      (j)   Indemnification by Buyer.  To the fullest extent permitted by law,
            ------------------------                                          
Buyer will indemnify and hold harmless each selling Holder, each underwriter of
Buyer Common Stock being sold by such Holders pursuant to this Section 5.10 and
each person, if any, who controls any such Holder or underwriter within the
meaning of the Securities Act or the Exchange Act against all actions, claims,
losses, damages, liabilities and expenses to which they or any of them become
subject under the Securities Act, the Exchange Act or under any other statute or
at common law or otherwise and, except as hereinafter provided, will promptly
reimburse each such Holder, each such underwriter and each such controlling
person, if any, for any legal or other expenses reasonably incurred by them or
any of them in connection with investigating or defending any actions whether or
not resulting in any liability, insofar as such losses, claims, damages,
expenses, liabilities or actions arise out of or are based upon any untrue
statement or alleged untrue statement of material fact in any registration
statement and any prospectus filed pursuant to Section 5.10 or any post-
effective amendment thereto or arise out of or are based upon any omission or
alleged omission 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 or any violation by Buyer of any rule or
regulation promulgated under the Securities Act or the Exchange Act applicable
to Buyer and relating to action or inaction required by Buyer in connection with
such registration; provided, however, that Buyer shall not be liable to any such
Holder, underwriter or controlling person in respect of any claims, losses,
damages, liabilities and expenses resulting from any untrue statement or alleged
untrue statement, or omission or alleged omission made in reliance upon and in




                                       35
<PAGE>
 
conformity with information furnished in writing to Buyer by such Holder or
underwriter specifically for use in connection with such registration statement
and prospectus or post-effective amendment.

        (k)   Indemnification by Holders.  To the fullest extent permitted by
              --------------------------                                     
law, each selling Holder of Registrable Shares registered in accordance with
this Section 5.10 will indemnify Buyer, each person, if any, who controls Buyer
within the meaning of the Securities Act or the Exchange Act, each director of
Buyer and each officer of Buyer who signs the registration statement and each
underwriter of Buyer Common Stock against any actions, claims, losses, damages,
liabilities and expenses to which they or any of them may become subject under
the Securities Act, the Exchange Act or under any other statute or at common law
or otherwise, and will promptly reimburse Buyer and each such director, officer,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them or any of them in connection with investigating or defending
any actions whether or not resulting in any liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact in any
registration statement and any prospectus filed pursuant to this Section 5.10 or
any post-effective amendment thereto, or any omission or alleged omission 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, which untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with information
furnished in writing to Buyer by such Holder or underwriter specifically for use
in connection with such registration statement, or any violation by such Holder
of any rule or regulation promulgated under the Securities Act or the Exchange
Act applicable to such Holder and relating to action or inaction required by
such Holder in connection with sales of securities covered by such registration,
prospectus or post-effective amendment; provided, however, that the obligations
of each such selling Holder hereunder shall be limited to an amount equal to the
gross proceeds to such Holder from the sale of such Holder's Registrable Shares
in such registration.

        (l)   Indemnification Procedures.  Each person entitled to
              --------------------------                          
indemnification under this Section 5.10 (an "Indemnified Person") shall give
notice to the party required to provide indemnification (the "Indemnifying
Person") promptly after such Indemnified Person has actual knowledge of any
claim as to which indemnity may be sought and shall permit the Indemnifying
Person to assume the defense of any such claim and any litigation resulting
therefrom, provided that counsel for the Indemnifying Person who conducts the
defense of such claim or any litigation resulting therefrom shall be approved by
the Indemnified Person (whose approval shall not unreasonably be withheld), and
the Indemnified Person may participate in such defense at such party's expense
(unless the Indemnified Person has reasonably concluded that there may be a
conflict of interest between the Indemnifying Person and the Indemnified Person
in such action, in which case the fees and expenses of counsel for the
Indemnified Person shall be at the expense of the Indemnifying Person), and
provided further that the failure of any Indemnified Person to give notice as
provided herein shall not relieve the Indemnifying Person of its obligations
under this Section 5.10 except to the extent the Indemnifying Person is
materially prejudiced thereby.  No Indemnifying Person, in the defense of any
such claim or litigation, shall (except with the consent of each Indemnified
Person) consent to entry of any judgment or enter into any settlement that does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified 



                                       36
<PAGE>
 
Person of a release from all liability in respect to such claim or litigation.
Each Indemnified Person shall furnish such information regarding itself or the
claim in question as an Indemnifying Person may reasonably request in writing
and as shall be reasonably required in connection with the defense of such claim
and litigation resulting therefrom.

        (m)   Contribution.  In order to provide for just and equitable
              ------------                                             
contribution in any case in which Buyer or any Holder makes a claim for
indemnification pursuant to this Section 5.10 but it is judicially determined
(by the entry of a final judgment or decree by a court of competent jurisdiction
and the expiration of time to appeal or the denial of the last right of appeal)
that such indemnification may not be enforced in such case notwithstanding that
indemnification would be available under this Section 5.10, in such case, then
Buyer and such Holder will contribute to the aggregate losses, claims, damages
or liabilities to which they may be subject (after contribution from others) in
such proportion as is appropriate to reflect (i) the relative fault of Buyer on
the one hand and of the Holder on the other in connection with the statements or
omission which resulted in such losses, claims, damages or liabilities, (ii) the
relative benefits received by Buyer and any Holder of Registrable Shares from
the offering of the securities covered by such Registration Statement, and (iii)
any other relevant equitable considerations, all subject to applicable law.  The
relative fault of Buyer on the one hand and of the Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by Buyer on the one hand or by the
Holder on the other, and each party's relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, however, that, in any such case no person or entity guilty of
fraudulent misrepresentation within the meaning of Section 11(f) of the
Securities Act will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

        (n)   "Market Stand-Off" Agreement.  In connection with an underwritten
              ----------------------------                                     
public offering of securities by Buyer pursuant to Section 5.10, each holder who
participates in the registration statement filed under the Securities Act for
such offering will not, to the extent requested in good faith by an underwriter
of securities of Buyer, sell or otherwise transfer or dispose of any Registrable
Shares not included in such registration statement (other than to donees or
partners of the Holder who agree to be similarly bound) for up to that period of
time, not to exceed sixty (60) days (the "Market Stand-Off Period"), following
the effective date of such registration statement of Buyer filed under the
Securities Act as is requested by the managing underwriter(s) of such offering;
provided that the officers and directors of Buyer who own stock of Buyer also
agree to such restrictions.  In order to enforce the foregoing covenant, Buyer
may impose stop transfer instructions with respect to the Registrable Shares of
each such holder (and the shares or securities of every other person subject to
the foregoing restriction) until the end of such period.

        (o)   Termination of Buyer's Obligations.  Buyer will have no
              ----------------------------------                     
obligations pursuant to this Section 5.10 with respect to Registrable Shares
held by a Holder if in the opinion of counsel to Buyer, which Buyer shall cause
to be delivered to the Holders within twenty (20) days after receipt of the
written notice described in subsection (b) of this Section 5.10 and upon which
Holders may rely, at the time of filing a registration statement such Holder may
sell all of such Holder's Registrable Shares in any single three (3)-month
period without registration under the 



                                       37
<PAGE>
 
Securities Act pursuant to Rule 144, provided that if at any time after a Holder
becomes eligible to sell the Registrable Shares pursuant to Rule 144 but before
such securities may be resold under Rule 144(k) Buyer fails to take all action
necessary to be taken by Buyer in order to allow Holder to sell under Rule 144,
Buyer shall have continuing obligations under this Section 5.10 until Holder may
sell such securities pursuant to Rule 144(k), at which time such continuing
obligations shall terminate.

            (p)   Other Piggyback Rights.  So long as any Target Stockholder has
                  ----------------------                                        
registration rights pursuant to this Section 5.10, Buyer shall not grant any
rights relating to the piggyback registration of its capital stock which are
superior or equal to the rights granted to the Holders under this Section 5.10.

     5.11   Reasonable Commercial Efforts and Further Assurances.  Each of the
            ----------------------------------------------------              
parties to this Agreement shall use reasonable commercial efforts to effectuate
the transactions contemplated hereby and to fulfill and cause to be fulfilled
the conditions to closing under this Agreement.  Each party hereto, at the
reasonable request of another party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be necessary or
desirable for effecting completely the consummation of this Agreement and the
transactions contemplated hereby.

     5.12   Hart-Scott-Rodino Act. Each of the Parties will file any
            ---------------------
Notification and Report Forms and related material that it may be required to
file with the Federal Trade Commission and the Antitrust Division of the United
States Department of Justice under the Hart-Scott-Rodino Act, will use its
reasonable best efforts to obtain an early termination of the applicable waiting
period, and will make any further filings pursuant thereto that may be
necessary, proper, or advisable.

     5.13   Listing of Buyer Shares. Buyer will use its reasonable best efforts
            -----------------------   
to cause the Merger Shares to be approved for listing on the Nasdaq SmallCap
Market, within the time prescribed therefor in the Nasdaq Stock Market rules and
regulations.

     5.14   Notice of Developments. Each Party will give prompt written notice
            ----------------------                            
to the other of any material adverse development causing a breach of any of its
own representations and warranties in Articles 3 and 4 above. No disclosure by
any Party pursuant to this Section 5.14, however, shall be deemed to amend or
supplement the Disclosure Schedule or to prevent or cure any misrepresentation,
breach of warranty, or breach of covenant.

     5.15   Exclusivity.  Target will not solicit, initiate, or encourage the
            -----------                                                      
submission of any proposal or offer from any Person relating to the acquisition
of all or substantially all of the capital stock or assets of Target (including
any acquisition structured as a merger, consolidation, or share exchange);
provided, however, that Target and its directors and officers will remain free
to participate in any discussions or negotiations regarding, furnish any
information with respect to, assist or participate in, or facilitate in any
other manner any effort or attempt by any Person to do or seek any of the
foregoing to the extent their fiduciary duties may require.  Target shall notify
Buyer immediately if any Person makes any proposal, offer, inquiry, or contact
with respect to any of the foregoing.

     5.16   Tax Treatment.  Neither Buyer nor the Surviving Corporation shall
            -------------   
take or agree to take any action that would prevent the Merger from constituting
a reorganization qualifying under the provisions of Section 368(a)(2)(D) of the
Code.

                                  ARTICLE 6.
                  TERMINATION; DEFAULT; AMENDMENT AND WAIVER

     6.1    Termination.  This Agreement may be terminated at any time prior to
            -----------                                                        
the Effective Time (i) by the mutual written consent of Buyer and Target; or
(ii) by written notice by either Buyer or Target if the Merger shall not have
been consummated by September 30, 1998, provided, however, that the right to
terminate this Agreement under this clause (ii) shall not be available to any
party whose failure to fulfill any obligation under this Agreement has been the
cause of or resulted in the failure of the Merger to occur on or before such
date; or (iii) by written notice by either Buyer or Target if there is a failure
to satisfy any of the conditions set forth in Section 8.1.   In the event of
such termination, this Agreement shall be abandoned without any liability or
further obligation to any other party to this Agreement unless otherwise stated
expressly herein.  This Section 6.1 shall not apply in the event of the failure
of the transactions contemplated by this Agreement to be consummated as a result
of a breach by Buyer, Target or Merger Sub of a representation, warranty or
covenant contained in this Agreement.
 
     6.2    Default; Remedies.  This Section 6.2 shall apply in the event that a
            -----------------                                                   
party refuses to consummate the transactions contemplated by this Agreement or
if any default under, or breach of any representation, warranty or covenant of,
this Agreement on the part of a party shall have occurred that results in the
failure to consummate the transactions contemplated hereby.
 
            (a) Default by Buyer or Merger Sub.  If Buyer or Merger Sub refuses 
                ------------------------------   
or fails to consummate the transactions contemplated by this Agreement for any
reason other than the failure of the conditions set forth in subsections (a),
(f), (g) and (k) of Section 8.2, then Buyer shall (i) pay to Target a break-up
fee in the amount of two million dollars ($2,000,000) (the "Break-up Fee"), any
portion of which may be satisfied by cancellation by Buyer of any then
outstanding indebtedness under any loans made by Buyer to Target in anticipation
of the Merger (the "Bridge Financing"), and (ii) create a joint development
arrangement with Target pursuant to which Buyer shall provide financing in the
amount of one million dollars ($1,000,000) (the "Project Financing") which
amount shall be paid periodically on an as-needed basis commencing on August 15,
1998, provided that such joint development project shall be governed by
definitive documentation to be negotiated in good faith by Buyer and Target
containing, without limitation, provisions governing the scope of the joint
development, ownership of any inventions resulting from the joint development
project and the respective obligations of the parties with respect to the joint
development project, and further provided that the Project Financing shall be
paid by Buyer in consideration of the submission of invoices by Target for the
costs incurred by Target in the course of the development project.  Any payment
or other performance by Buyer pursuant to this Section 6.2 shall be in
consideration of the expenses incurred by and efforts expended by and
opportunities lost by Target.  The parties agree that in such circumstances it
would be impossible to determine the actual damages which any party may suffer
and that therefore such payments shall be in lieu of such actual damages and
shall be full 


                                       39
<PAGE>
 
and complete liquidated damages and shall constitute the sole remedy in the
event of such default by Buyer or Merger Sub.

            (b)   Default by Target.  If Target delivers written notice (a
                  -----------------                                       
"Termination Notice") to Buyer that Target is terminating this Agreement through
no fault of Buyer or Merger Sub, and Target consummates an acquisition
transaction of any type with another party nat any time within sixty (60) days
after the date of the Termination Notice, Target shall pay Buyer an amount equal
to the highest single amount outstanding at any time under the Bridge Financing.

     6.3    Amendment.  This Agreement may be amended by the parties hereto, by
            ---------                                                          
action taken or authorized by their respective Boards of Directors.  This
Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties hereto.

     6.4    Extension; Waiver.  At any time prior to the Effective Time, the
            -----------------                                               
parties hereto, by action taken or authorized by their respective Boards of
Directors, may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto and (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in a written instrument signed on behalf of such party.

                                  ARTICLE 7.
                          ESCROW AND INDEMNIFICATION.

     7.1    Escrow Fund
            -----------

            (a)    At the Closing, ten percent (10%) of the total number of
Merger Shares issued by Buyer at Closing (the "Escrow Shares") shall be
registered in the name of, and be deposited with Durham, Evans, Jones & Pinegar,
P.C. (or another institution selected by Buyer with the reasonable consent of
Target) as escrow agent (the "Escrow Agent"), such deposit to constitute the
Escrow Fund and to be governed by the terms set forth herein and in the Escrow
Agreement attached hereto as Exhibit C. The Escrow Fund shall be available to
compensate Buyer pursuant to the indemnification obligations of the Target
Stockholders as set forth in Section 7.2. If Buyer issues any Additional Escrow
Shares (as defined below), such shares will be issued in the name of the Escrow
Agent and delivered to the Escrow Agent in the same manner as the Escrow Shares
delivered at the Closing.

            (b)    Except for dividends paid in stock declared with respect to

to Section 7.l(a) hereof, any cash dividends, dividends payable in securities or
other distributions of any kind made in respect of the Escrow Shares will be
delivered to the Target Stockholders on a pro rata basis. Each Target
Stockholder will have voting rights with respect to the Escrow Shares deposited
in the Escrow Fund with respect to such stockholder so long as such Escrow
Shares are held in escrow, and Buyer will take all reasonable steps necessary to
allow the exercise of such rights. While the Escrow Shares remain in the Escrow
Agent's possession pursuant to this Agreement, the Target Stockholders will



                                       40

retain and will be able to exercise all other incidents of ownership of said
Escrow Shares which are not inconsistent with the terms and conditions of this
Agreement.

made by Target or Buyer herein, or in any certificate, schedule or exhibit
delivered pursuant hereto, shall survive the Closing and continue in full force
and effect until the first anniversary of the Closing Date (sometimes referred
to herein as the "Termination Date").
 
            (b)   Subject to this Section 7.2, Buyer shall indemnify and hold
harmless Target, and its officers, directors, agents, attorneys, employees, and
each person, if any, who controls or may control Target, and the Target
Stockholders (hereinafter referred to individually as a "Target Indemnified
Person" and collectively as "Target Indemnified Persons") from and against any
and all losses, costs, damages, liabilities and expenses arising from claims,
demands, actions and causes of action, including, without limitation, legal fees
(collectively, "Damages") arising out of any misrepresentation or breach of or
default in connection with any of the representations, warranties, covenants and
agreements given or made by Buyer in this Agreement, the Buyer Disclosure
Schedules or any exhibit, schedule or other instrument made or given in
connection with the execution and delivery of this Agreement.  Target and its
affiliates and the Target Stockholders shall act in good faith and in a

            (c)   Subject to the limitations set forth in this Section 7.2, the
Target Stockholders shall indemnify and hold harmless Buyer and the Surviving
Corporation and their respective officers, directors, agents, attorneys and
employees, and each person, if any, who controls or may control Buyer or the
Surviving Corporation within the meaning of the Securities Act (hereinafter

"Buyer Indemnified Persons") (the Target Indemnified Persons and the Buyer
Indemnified Persons shall be referred to collectively in Article 7 as
"Indemnified Persons")  from and against any and all Damages arising out of any
misrepresentation or breach of or default in connection with any of the
representations, warranties, covenants and agreements given or made by Target in
this Agreement, the Target Disclosure Schedules or any exhibit, schedule or
other instrument made or given in connection with the execution and delivery of
this Agreement.  Buyer and its affiliates shall act in good faith and in a
commercially reasonable manner to mitigate any Damages they may suffer.  The

Persons shall be the Escrow Fund.

     7.3    Escrow Period; Release from Escrow.
            ---------------------------------- 

            (a)   The Escrow Period shall terminate upon the expiration of
twelve months after the Effective Time; provided, however, that a portion of the
Escrow Fund, which, in the reasonable judgment of Buyer, subject to the
objection of the Stockholders' Agent and the subsequent arbitration of the
matter in the manner provided in Section 7.6 hereof, is necessary to satisfy any
unsatisfied claims specified in any Officer's Certificate, as that term is
defined in Section 7.4, theretofore delivered to the Escrow Agent prior to
termination of the Escrow Period with respect to facts and circumstances
existing prior to expiration of the Escrow Period, shall remain in the Escrow
Fund until such claims have been resolved.

            (b)   Within three (3) business days after the Termination Date (the
"Release Date"), the Escrow Agent shall release from escrow to the Target
Stockholders their pro rata portion of the Escrow Shares and Additional Escrow
Shares less with respect to each such Target Stockholder the number of Escrow
Shares and Additional Escrow Shares with a value (as determined pursuant to
Section 7.4) equal to (A) such Target Stockholder's pro rata portion of any
liability delivered to Buyer in accordance with Section 7.4 in satisfaction of
indemnification claims by Indemnified Persons and (B) such Target Stockholder's
pro rata portion of any liability subject to delivery to Indemnified Persons in
accordance with Section 7.3(a) with respect to any pending but unresolved
indemnification claims of Indemnified Persons.  The Escrow Agent shall in all
events release all remaining Escrow Shares and Additional Escrow Shares held as
a result of clause (B) on or before that date that shall be three (3) months
after the Release Date (the "Disputed Claim Release Date") unless on or prior to
the Disputed Claim Release Date the parties shall have resolved any dispute or
Buyer or the Stockholders' Agent shall have commenced an action or arbitration
to resolve such claim.  Escrow Shares and Additional Escrow Shares shall be
released to the respective Target Stockholders in proportion to their respective
ownership interest in Target immediately prior to the Effective Time.  Buyer
will take such action as may be necessary to cause such certificates to be
issued in the names of the appropriate persons.  Certificates representing
Escrow Shares and Additional Escrow Shares so issued that are subject to resale
restrictions under applicable securities laws will bear a legend to that effect.
No fractional shares shall be released and delivered from Escrow to the Target
Stockholders.  In lieu of any fraction of an Escrow Share to which a Target
Stockholder would otherwise be entitled, such holder will receive from Buyer an
amount of cash (rounded to the nearest whole cent) equal to the product of such
fraction multiplied by the Indemnification Price (as defined below).

            (c)   No Escrow Shares or Additional Escrow Shares or any beneficial
interest therein may be pledged, sold, assigned or transferred, including by
operation of law, by any Target Stockholder or be taken or reached by any legal
or equitable process in satisfaction of any debt or other liability of any such
stockholder, prior to the delivery to such stockholder of his pro rata portion
of the Escrow Fund by the Escrow Agent as provided herein.

            (d)   The Escrow Agent is hereby granted the power to effect any
transfer of Escrow Shares contemplated by this Agreement.  Buyer shall cooperate
with the Escrow Agent in promptly issuing stock certificates to effect such
transfers.

     7.4    Claims upon Escrow Fund.  Upon receipt by the Escrow Agent on or
            -----------------------                                         
before the Release Date of a certificate signed by any officer of Buyer (an
"Officer's Certificate") stating that with respect to the indemnification
obligations of the Target Stockholders set forth in Section 7.2, Damages exist
and specifying in reasonable detail the individual items of such Damages
included in the amount so stated, the date each such item was paid, or properly
accrued or arose, and the nature of the misrepresentation, breach of warranty or
claim to which such item is related, the Escrow Agent shall, subject to the
provisions of this Section 7, deliver to Buyer out of the Escrow Fund, as
promptly as practicable, Escrow Shares, Additional Escrow Shares or other assets
held in the Escrow Fund having a value equal to such Damages.  For the purpose
of compensating Buyer for its Damages pursuant to this Agreement, Escrow Shares
shall be valued at the average closing "bid" price of a Buyer Share for the ten
(10) trading days immediately preceding the date on which the Officer's
Certificate is delivered to the Escrow Agent, as reported on the Nasdaq SmallCap
Market (the "Indemnification Price").  In determining the amount of any Damage
attributable to a breach, any materiality standard contained in a
representation, warranty or covenant of Buyer shall be disregarded.

     7.5    Objections to Claims.  At the time of delivery of any Officer's
            --------------------                                           
Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate
shall be delivered to the Stockholders' Agent (defined in Section 7.7 below) by
certified mail, return receipt requested, and for a period of thirty (30) days
after such delivery, the Escrow Agent shall make no delivery of Escrow Shares or
Additional Escrow Shares unless the Escrow Agent shall have received written
authorization from the Stockholders' Agent to make such delivery.  After the
expiration of such thirty (30) day period, the Escrow Agent shall make delivery
of Escrow Shares or Additional Escrow Shares in accordance with Section 7.4
hereof, provided that no such payment or delivery may be made if the
Stockholders' Agent shall object in a written statement to the claim made in the
Officer's Certificate, and such statement shall have been delivered to the
Escrow Agent and to Buyer prior to the expiration of such thirty (30) day
period.

     7.6    Resolution of Conflicts and Arbitration.
            --------------------------------------- 

            (a)    In case the Stockholders' Agent shall so object in writing to
any claim or claims by Buyer made in any Officer's Certificate, Buyer shall have
thirty (30) days to respond in a written statement to the objection of the
Stockholders' Agent. If after such thirty (30) day period there remains a
dispute as to any claims, the Stockholders' Agent and Buyer shall attempt in
good faith for thirty (30) days to agree upon the rights of the respective
parties with respect to each of such claims. If the Stockholders' Agent and
Buyer should so agree, a memorandum setting forth such agreement shall be
prepared and signed by both parties and shall be furnished to the Escrow Agent.
The Escrow Agent shall be entitled to rely on any such memorandum and shall
distribute the Escrow Shares, Additional Shares or other property from the
Escrow Fund in accordance with the terms thereof.

            (b)    If no such agreement is reached after good faith negotiation
as set forth above, either Buyer or the Stockholders' Agent may, by written
notice to the other, demand arbitration of the matter unless the amount of the
damage or loss is at issue in pending litigation with a third party, in which
event arbitration shall not be commenced until such amount is ascertained or


                                       43
<PAGE>
 
both parties agree to arbitration; and in either such event the matter shall be
settled by arbitration conducted by one arbitrator mutually selected by Buyer
and the Stockholders' Agent. If Buyer and the Stockholders' Agent do not agree
on such arbitrator, either Buyer or Stockholders' Agent may request that the
American Arbitration Association select the arbitrator. The arbitrator shall set
a limited time period and establish procedures designed to reduce the cost and
time for discovery while allowing the parties an opportunity, adequate in the
sole judgment of the arbitrators, to discover relevant information from the
opposing parties about the subject matter of the dispute. The arbitrator shall
rule upon motions to compel or limit discovery and shall have the authority to
impose sanctions, including attorneys' fees and costs, to the same extent as a
court of competent law or equity, should the arbitrator determine that discovery
was sought without substantial justification or that discovery was refused or
objected to without substantial justification. The decision of the arbitrator
shall be written, shall be in accordance with applicable law and with this
Agreement, and shall be supported by written findings of fact and conclusion of
law which shall set forth the basis for the decision of the arbitrator. The
decision of the arbitrator as to the validity and amount of any claim in such
Officer's Certificate shall be binding and conclusive upon the parties to this
Agreement, and notwithstanding anything in Section 7.5 hereof, the Escrow Agent
shall be entitled to act in accordance with such decision and make or withhold
payments out of the Escrow Fund in accordance therewith.

        (c)   Judgment upon any award rendered by the arbitrator may be entered
in any court having jurisdiction.  Any such arbitration shall be held in Salt
Lake County, Utah under the commercial rules then in effect of the American
Arbitration Association.  For purposes of this Section 7.6(c), in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is at issue, Buyer shall be deemed to be the Non-
Prevailing Party unless the arbitrators award Buyer more than one-half ( 1/2) of
the amount in dispute, plus any amounts not in dispute; otherwise, the Target
Stockholders for whom the Escrow Shares, Additional Escrow Shares (if any) or
other property deposited into escrow have been deposited in the Escrow Fund
shall be deemed to be the Non-Prevailing Party.  The Non-Prevailing Party to an
arbitration shall pay its own expenses, the fees of the arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including attorneys' fees and costs, reasonably incurred by the other party to
the arbitration.

exercise of reasonable judgment and any act done or omitted pursuant to the
advice of counsel shall be conclusive evidence of such good faith. The Target
Stockholders shall severally indemnify the Stockholders' Agent and hold him
harmless against any loss, liability or expense incurred without gross
negligence or bad faith on the part of the Stockholders' Agent and arising out
of or in connection with the acceptance or administration of his duties

            (c)   The Stockholders' Agent shall have reasonable access to
information about Target and the reasonable assistance of Target's officers and
employees for purposes of performing his duties and exercising his rights

Stockholders for whom Merger Shares otherwise issuable to them are deposited in

Stockholder, and the Escrow Agent and Buyer may rely upon any decision, act,
consent or instruction of the Stockholders' Agent as being the decision, act,
consent or instruction of each and every such Target Stockholder.  The Escrow
Agent and Buyer are hereby relieved from any liability to any person for any
acts done by them in accordance with such decision, act, consent or instruction
of the Stockholders' Agent.

     7.9    Third-Party Claims.  In the event Buyer becomes aware of a third-

party claim which Buyer believes may result in a demand against the Escrow Fund,
Buyer shall notify the Stockholders' Agent of such claim, and the Stockholders'
Agent and the Target Stockholders for whom Merger Shares otherwise issuable to
them are deposited in the Escrow Fund shall be entitled, at their expense, to
participate in any defense of such claim. Buyer shall have the right in its sole
discretion to settle any such claim. In the event that the Stockholders' Agent
has consented to any such settlement, the Stockholders' Agent shall have no
power or authority to object under Section 7.5 or any other provision of this
Section 7 to the amount of any claim by Buyer against the Escrow Fund for
indemnity with respect to such settlement.

                               AMENDMENT NO. 1 TO
                               ------------------
                          AGREEMENT AND PLAN OF MERGER
                          ----------------------------


     This Amendment No. 1 to Agreement and Plan of Merger is entered into as of
the 2nd day of September, 1998, by and among Articulate Systems, Inc., a
Delaware corporation ("Target"), fonix corporation, a Delaware corporation
("Buyer"), and ASI Acquisition Corporation, a Utah corporation and wholly-owned
subsidiary of fonix corporation ("Merger Sub"). Capitalized terms used herein
and not otherwise defined shall have the meanings ascribed to them in the Merger
Agreement.

     WHEREAS, Buyer, Merger Sub and Target have entered into a certain Agreement
and Plan of Merger (the "Merger Agreement") dated as of July 31, 1998, pursuant
to which Merger Sub will merge with and into Target and continue thereafter as
the surviving corporation (the "Merger");

     WHEREAS, as set forth in Section 2.4(r) of the Merger Agreement, it is
intended by the parties that the Merger shall constitute a tax-free
reorganization within the meaning of Section 368(a)(2)(D) of the Internal
Revenue Code of 1986, as amended, and consistent with that intention, the
parties desire to amend the Merger Agreement to provide that additional shares
of capital stock of Buyer (in addition to that required under Section 2.4(e) of
the Merger Agreement) will be issued upon the conversion of the Target Shares in
the Merger;

     WHEREAS, Section 9.10 of the Merger Agreement permits the parties thereto,
with the prior authorization of their respective Boards of Directors, to
mutually amend any provision of the Merger Agreement prior to the Effective
Time; and

     WHEREAS, the Board of Directors of each of Buyer, Merger Sub and Target
have authorized such party to enter into this Amendment No. 1 to Agreement and
Plan of Merger.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     1.   Section 2.4(e) of the Merger Agreement is amended in its entirety as
follows:

          "(e) Conversion of Target Shares.
               --------------------------- 

               (i) At and as of the Effective Time, and without any further
                   action by any of the Target Stockholders, subject to Section
                   2.4(f), each outstanding Target Share shall be converted into
                   the right to receive: (i) that number of validly issued,
                   fully paid and nonassessable unregistered Buyer Shares
                   ("Merger Shares") which equals the amount obtained by
                   dividing (A) the quotient of (a) $11,800,000 divided by (b)
                   the Closing Price, by (B) 2,916,093 (the "Exchange Ratio"),
                   (ii) cash in the amount of
<PAGE>
 
          $13,200,000 divided by 2,916,093 (the "Cash Payment"), and (iii) .7057
          additional unregistered Buyer Shares (the "Additional Merger Shares").
          "Closing Price" shall mean $3.5427. No Target Share shall be deemed to
          be outstanding or to have any rights other than those rights set forth
          in this Section 2.4 after the Effective Time.

    (ii)  At Closing, Buyer shall cause to be distributed to T. Ivan Mimica, as
          agent for the Target Stockholders (the "Agent"), a certificate or
          certificates representing all Additional Merger Shares. Such shares
          shall be beneficially owned pro rata by the Target Stockholders who
          receive Merger Consideration. Any cash dividends, dividends paid in
          stock declared with respect to the Additional Merger Shares, dividends
          payable in any other security or other distributions of any kind made
          in respect of the Additional Merger Shares shall be delivered to the
          Target Stockholders on a pro rata basis. Each Target Stockholder shall
          have voting rights with respect to the Additional Merger Shares held
          by the Agent, and the Target Stockholders by their approval of the
          Merger Agreement constitute and appoint the Agent, with full power of
          substitution, and authorize the Agent to represent and to vote the
          Additional Merger Shares in the Agent's reasonable discretion at any
          meeting of the stockholders of Buyer.

    (iii) During the ninety (90) day period following the Effective Date, Buyer
          upon written notice to the Agent shall be entitled to require the
          Additional Merger Shares to be exchanged (the "Exchange") for an equal
          number of shares of a new class of common stock of Buyer to be
          designated Class B Common Stock (the "Exchange Shares") as set forth
          in an amendment to Buyer's Certificate of Incorporation, the form of
          which is attached hereto Exhibit F (the "Charter Amendment"), provided
          that Buyer shall have obtained all requisite stockholder approval for
          the authorization and issuance of such Class B Common Stock, after
          which the Charter Amendment will be filed by Buyer with the Secretary
          of State of Delaware. Except as set forth in the Charter Amendment,
          the Class B Common Stock shall be identical in all respects to the
          Buyer Shares, which shall be redesignated along with all other
          outstanding shares of common stock of Buyer as Class A Common Stock
          under the Charter Amendment. In the Exchange, Buyer shall distribute
          the Exchange Shares directly to the Target Stockholders and the agency
          described above shall terminate. If Buyer shall not have obtained the
          requisite stockholder approvals and required the Exchange within the
          ninety (90) day period referenced above, then the Agent, at the sole
          cost and expense of
<PAGE>
 
               Buyer, shall immediately distribute the Additional Merger Shares
               to the Target Stockholders on a pro rata basis.

          (iv) Buyer agrees to indemnify and hold the Agent harmless from and
               against any and all losses, damages, taxes, liabilities and
               expenses that may be incurred, directly or indirectly, by the
               Agent, arising out of or in connection with its acceptance of
               appointment as the Agent hereunder and/or the performance of its
               duties pursuant to this Agreement, including, but not limited to,
               all legal costs and expenses of the Agent incurred defending
               itself against any claim or liability in connection with its
               performances hereunder and the costs of recovery of amounts
               pursuant to this Section 2.4(e)(iv), except for those arising out
               of the willful misconduct or gross negligence of the Agent. Agent
               shall be deemed a third party beneficiary of this Agreement with
               respect to Section 2.4(e)(iv)."

     2.   This Amendment No. 1 embodies the entire agreement and understanding
          between the parties hereto with respect to the subject matter hereof
          and supersedes all other agreements and understandings related to such
          subject matter.

     3.   This Amendment No. 1 may be amended and the observance of any term of
          this Agreement may be waived (either generally or in a particular
          instance and either retroactively or prospectively) by mutual written
          consent of each of the parties hereto.

     4.   This Amendment No. 1 may be executed in one or more counterparts, each
          of which shall be deemed to be an original, but all of which shall be
          one and the same document.

     5.   The invalidity or unenforceability of any provision of this Amendment
          No. 1 shall not affect the validity or enforceability of any other
          provision hereof.

     6.   Except to the extent specifically and expressly amended hereby, the
          terms and conditions of the Merger Agreement shall be unaffected
          hereby and shall continue in full force and effect.

preferences, privileges, and restrictions of such series of Preferred Stock,
including the annual rate or rates of dividends for the particular series and
whether such dividends shall be cumulative or noncumulative; the redemption

such conversion rights; the voting rights; anti-dilution rights; terms of
redemption (including sinking fund provisions); the number of shares
constituting any series, and the designation of such series; and to classify or
reclassify any unissued Preferred Stock by fixing or altering from time to time
