Certificate of Vote), (c) conflict with, result in breach of, constitute a 
default under, or require any notice, consent or waiver under, any contract, 
agreement or other instrument to which the Company is a party or by which it

Securities and Exchange Commission (the "SEC"), and (ii) its Quarterly Report 
on Form 10-Q for the quarter ended June 30, 1996, as filed with the SEC (such

Company Reports constitute all of the documents required to be filed by the 
Company under Section 13 of the Securities Exchange Act of 1934, as amended 
(the "Exchange Act") with the SEC since March 31, 1996.  As of their 
respective dates, the Company Reports did not contain any untrue statement of 
a material fact or omit to state a material fact required to be stated 
therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading.  The audited 
financial statements and unaudited interim financial statements of the 
Company included in the Company Reports (i) comply as to form in all material 
respects with applicable accounting requirements and the published rules and 
regulations of the SEC with respect thereto, (ii) have been prepared in 
accordance with GAAP applied on a consistent basis throughout the periods 
covered thereby (except as may be indicated therein or in the notes thereto, 
and in the case of quarterly financial statements, as permitted by Form 10-Q 
under the Exchange Act), (iii) fairly present the consolidated financial 
condition, results of operations and cash flows of the Company as of the 
respective dates thereof and for the periods referred to therein, and (iv) 
are consistent with the books and records of the Company.

       (b)  The Company has provided to the Purchaser a copy of its press 
release dated September 30, 1996 with respect to the financial results of the 
Company for the quarter then ended.  The Company has also provided to and 
discussed with the Purchaser such information as the Purchaser has requested 
(to the extent available) regarding the financial results of the Company for 
such quarter and the current operations, financial condition (including the 
amount of available cash) and plans of the Company.

       3.6  ABSENCE OF MATERIAL ADVERSE CHANGES.  Except as disclosed by the 
Company to the Purchaser prior to the date hereof, since June 30, 1996, there 
has not been any material



                                  -4-




adverse change in the assets, business, financial condition or results of 
operations of the Company.

       3.7  LITIGATION.  There is no action, suit or proceeding, or 
governmental inquiry or investigation, pending, or, to the best of the 
Company's knowledge, any basis therefor or threat thereof, against the 
Company, which questions the validity of this Agreement or the right of the 
Company to enter into it, or which might result, either individually or in 
the aggregate, in any material adverse change in the business, prospects, 
assets or condition, financial or otherwise, of the Company.

    4. REPRESENTATIONS OF THE PURCHASER.  The Purchaser represents and 
warrants to the Company as follows:

       4.1  INVESTMENT.  The Purchaser is acquiring the Shares, and the 
shares of Common Stock into which the Shares may be converted, for its own 
account for investment and not with a view to, or for sale in connection

       4.2  AUTHORITY.  The Purchaser has full power and authority to enter 
into and to perform this Agreement in accordance with its terms.  The 
Purchaser represents that it has not been organized, reorganized or 
recapitalized specifically for the purpose of investing in the Company.  This 
Agreement has been duly executed and delivered by the Purchaser and 
constitutes a valid and binding obligation of the Purchaser, enforceable 
against it in accordance with its terms.

representations concerning the Company contained in this Agreement and has

written information which it has requested and have answered to the 
Purchaser's satisfaction all inquiries made by the Purchaser; and the

financially to bear the risks thereof, including a complete loss of its 
investment.

in making this investment, it has not relied upon any information or 
representations and warranties of Hambrecht & Quist LLC, including without 
limitation representations and warranties regarding the Company, its 
officers, financial condition, business and prospects, or the terms of the 
purchase of the Shares.

       4.5  STATUS.  The Purchaser is an "accredited Investor" as that term 
is defined in Rule 501 of Regulation D promulgated under the Securities Act.

       (a)  within 90 days after the end of each fiscal year of the Company, 
an audited balance sheet of the Company as at the end of such year, and 
audited statements of income and of cash flows of the Company for such year, 
certified by certified public accountants of established national reputation

       5.3  RESERVATION OF COMMON STOCK.  The Company shall reserve and 
maintain a sufficient number of shares of Common Stock for issuance upon 
conversion of all of the outstanding Shares. 

    6. TRANSFER OF SHARES.

       6.1  RESTRICTED SHARES.  "Restricted Shares" means (i) the Shares, 
(ii) the shares of Common Stock issued or issuable upon conversion of the 
Shares, and (iii) any other shares of capital stock of the Company issued in 
respect of such shares (as a result of stock splits, stock dividends, 
reclassifications, recapitalizations, or similar events); PROVIDED, HOWEVER, 
that shares of Common Stock which are Restricted Shares shall cease to be 
Restricted Shares (i) upon any sale pursuant to a registration statement 
under the Securities Act, Section 4(1) of the Securities Act or Rule 144 
under the Securities Act, or (ii) at such time as they become eligible for 
sale under Rule 144(k) under the Securities Act.  

       6.2  REQUIREMENTS FOR TRANSFER.  Restricted Shares shall not be sold 
or transferred unless either (a) they first shall have been registered under 
the Securities Act, or (b) the Company first shall have been furnished with 
an opinion of legal counsel, reasonably satisfactory to the Company, to the 
effect that such sale or transfer is exempt from the registration 
requirements of the Securities Act.

       6.3  LEGEND.  Each certificate representing Restricted Shares shall 
bear a legend substantially in the following form: 

       "The shares represented by this certificate have not been registered
       under the Securities Act of 1933, as amended, and may not be offered,
       sold or otherwise transferred, pledged or hypothecated unless and
       until such



                                  -7-




       shares are registered under such Act or an opinion of counsel 
       satisfactory to the Company is obtained to the effect that 
       such registration is not required."


    The foregoing legend shall be removed from the certificates representing 
any Restricted Shares, at the request of the holder thereof, at such time as 
they become eligible for resale pursuant to Rule 144(k) under the Securities 
Act.

    7. REGISTRATION RIGHTS.

       7.1  REGISTRATION OF SHARES.

            (a)  The Company shall use its best efforts to file with the SEC, 
as promptly as practicable following the Closing, a registration statement on 
Form S-3 (the "Registration Statement") covering the resale to the public by 
the Purchaser of the shares of common stock of the Company issued upon 
conversion of the Shares (the "Registrable Shares").  The Company shall use 
its best efforts to cause the Registration Statement to be declared effective 
by the SEC as soon as practicable, but in no event later than January 15, 
1997.  The Company shall cause the Registration Statement to remain effective 
until the date three years after the Closing Date or such earlier time as all 
of the Registrable Shares covered by the Registration Statement have been 
sold pursuant thereto.  

            (b)  In the event the Registration Statement has not been 
declared effective under the Securities Act by the SEC by the close of 
business on January 15, 1997, the Company shall issue to the Purchaser within 
15 days following the end of each calendar month (beginning with January 
1997), until the Registration Statement is declared effective, such number of 
shares of Series C Preferred Stock as is equal to (i) (A) the number of 
shares purchased at the Closing pursuant to this Agreement multiplied by (B) 
$.001 multiplied by (C) the number of weeks (including fractions of a week) 
during such month for which the Registration Statement was not declared 
effective (excluding, for January 1997, any period prior to the close of 
business on January 15, 1997) divided by (ii) (A) the average of the daily 
trading volume-weighted last reported sale prices per share of the common 
stock of the Company on the Nasdaq National Market, as reported by Nasdaq, on 
the last ten trading days of such month multiplied by (B) four.  Any shares 
of Series C Preferred Stock issuable pursuant to this Section 7.1(b) shall be 
considered "Shares" for purposes of Sections 4, 6 and 7 of this Agreement.  
The issuance by the Company of such shares of Series C Preferred



                                  -8-




Stock pursuant to this Section 7.1(b) shall constitute liquidated damages 
with respect to the Company's failure to cause the Registration Statement to 
be declared effective by January 15, 1997, and shall be in lieu of any other 
claims or damages to which the Purchaser may be entitled with respect thereto.

       7.2  LIMITATIONS ON REGISTRATIONS.

            (a)  The Company may, by written notice to the Purchaser, (i) 
delay the filing or effectiveness of the Registration Statement or (ii) 
suspend the Registration Statement after effectiveness and require that the 
Purchaser immediately cease sales of shares pursuant to the Registration 
Statement, in the event that (A) the Company files a registration statement 
(other than a registration statement on Form S-8 or Form S-4 or their 
successor forms) with the SEC for a public offering of its securities, or (B) 
the Company is engaged in any activity or transaction or preparations or 
negotiations for any activity or transaction that the Company desires to keep 
confidential for business reasons, if the Company determines in good faith 
that the public disclosure requirements imposed on the Company under the 
Securities Act in connection with the Registration Statement would require 
disclosure of such activity, transaction, preparations or negotiations.  
Notwithstanding the foregoing, such right shall not be exercised more than 
twice in any 12-month period, and no such delay or suspension may continue 
for more than 30 days.

            (b)  If the Company delays or suspends the Registration Statement 
or requires the Purchaser to cease sales of shares pursuant to paragraph (a) 
above, the Company shall, as promptly as practicable following the 
termination of the circumstance which entitled the Company to do so, take 
such actions as may be necessary to file or reinstate the effectiveness of 
the Registration Statement and/or give written notice to the Purchaser 
authorizing them to resume sales pursuant to the Registration Statement.  If 
as a result thereof the prospectus included in the Registration Statement has 
been amended to comply with the requirements of the Securities Act, the 
Company shall enclose such revised prospectus with the notice to the 
Purchaser given pursuant to this paragraph (b), and the Purchaser shall make 
no offers or sales of shares pursuant to the Registration Statement other 
than by means of such revised prospectus.  Moreover, if the Company delays or 
suspends the Registration Statement or requires the Purchaser to cease sales 
of shares pursuant to clause (i) of paragraph (a) above as a result of the 
circumstances set forth in clause (A) of such paragraph (a), the Company 
shall permit the Purchaser to include



                                  -9-




in a registration statement filed by the Company during such period, any 
Registrable Shares that would have been included in the Registration 
Statement, subject to the right of the Company to limit the number of 
Registrable Shares to be included in a registration statement relating to a 
unwritten offering of securities of the Company if the managing underwriter 
of such offering determines that the inclusion of such shares in such 
offering would adversely affect the marketability of such offering.

       7.3  REGISTRATION PROCEDURES.

            (a)  In connection with the filing by the Company of the 
Registration Statement, the Company shall furnish to the Purchaser a copy of 
the prospectus, including a preliminary prospectus, in conformity with the 
requirements of the Securities Act.

            (b)  The Company shall use its best efforts to register or 
qualify the Registrable Shares covered by the Registration Statement under 
the securities laws of such states as the Purchaser shall reasonably request.

            (c)  If the Company has delivered preliminary or final 
prospectuses to the Purchaser and after having done so the prospectus is 
amended to comply with the requirements of the Securities Act, the Company 
shall promptly notify the Purchaser and, if requested by the Company, the 
Purchaser shall immediately cease making offers or sales of shares under the 
Registration Statement and return all prospectuses to the Company.  The 
Company shall promptly provide the Purchaser with revised prospectuses and, 
following receipt of the revised prospectuses, the Purchaser shall be free to 
resume making offers and sales under the Registration Statement.

            (d)  The Company shall pay the expenses incurred by it in 
complying with its obligations under this Section 7 including all 
registration and filing fees, exchange listing fees, fees and expenses of 
counsel for the Company, and fees and expenses of accountants for the 
Company, but excluding (i) any brokerage fees, selling commissions or 
underwriting discounts incurred by the Purchaser in connection with sales 
under the Registration Statement.  

       7.4  REQUIREMENTS OF THE PURCHASER.

            (a)  The Purchaser shall furnish to the Company in writing such 
information regarding the Purchaser and the proposed

                 Certificate of Vote of Directors Establishing

                          a Series of a Class of Stock

                                      of

                                INTERLEAF, INC.

                                To be Designated

                       SERIES C CONVERTIBLE PREFERRED STOCK


    Interleaf, Inc., a Massachusetts corporation (the "Corporation"), 
pursuant to authority conferred on the Board of Directors of the Corporation 
by the Articles of Organization and in accordance with the provisions of 
Section 26 of the Business Corporation Law of the Commonwealth of 
Massachusetts, certifies that the Board of Directors of the Corporation, at a 
meeting duly called and held, at which a quorum was present and acting 
throughout, duly voted to establish a series of Preferred Stock, $0.10 par 
value per share, of the Corporation and that the designation and number of 
shares, and the preferences, voting powers, qualifications, and special or 
relative rights or privileges thereof are fixed as follows:

    1. DESIGNATION AND AMOUNT.  The shares of such series shall be designated 
as "Series C Convertible Preferred Stock" (the "Series C Preferred Stock") 
and the number of shares constituting the Series C Preferred Stock shall be 
1,200,000.

    2. DIVIDENDS.  The holders of shares of Series C Preferred Stock shall be 
entitled to receive, out of funds legally available therefor, dividends of 
$.24878 per share on April 15, 1998 and October 15, 1998, and $.49756 per 
share on each April 15






and October 15 thereafter (subject in each case to appropriate adjustment in 
the event of any stock dividend, stock split, combination or other similar 
recapitalization affecting such shares).  Such dividends shall accrue and 
shall be cumulative, from and after October 15, 1997, whether or not declared 
by the Board of Directors.

    3. LIQUIDATION, DISSOLUTION OR WINDING UP; CERTAIN MERGERS,
       CONSOLIDATIONS AND ASSET SALES.

       (a)  In the event of any voluntary or involuntary liquidation, 
dissolution or winding up of the Corporation, the holders of shares of Series 
C Preferred Stock then outstanding shall be entitled to be paid out of the 
assets of the Corporation available for distribution to its stockholders, 
after and subject to the payment in full of all amounts required to be 
distributed to the holders of any other class or series of stock of the 
Corporation ranking on liquidation prior and in preference to the Series C 
Preferred Stock (collectively referred to as "Senior Preferred Stock"), but 
before any payment shall be made to the holders of Common Stock, Series A 
Preferred Stock, Series B Preferred Stock or any other class or series of 
stock ranking on liquidation junior to the Series C Preferred Stock (such 
Common Stock, Series A Preferred Stock, Series B Preferred Stock and other 
stock being collectively referred to as "Junior Stock") by reason of their 
ownership thereof, an amount equal to $9.9512 per share (subject to 
appropriate adjustment in the event of any stock dividend, stock split, 
combination or other similar recapitalization affecting such shares), plus 
any declared or accrued but unpaid dividends on such shares. If upon any such 
liquidation, dissolution or winding up of the Corporation the remaining 
assets of the Corporation available for distribution to its stockholders 
shall be insufficient to pay the holders of shares of Series C Preferred 
Stock the full amount to which they shall be entitled, the holders of shares 
of Series C Preferred Stock and any class or series of stock ranking on 
liquidation on a parity with the Series C Preferred Stock shall share ratably 
in any distribution of the remaining assets and funds of the Corporation in 
proportion to the respective amounts which would otherwise be payable in 
respect of the shares held by them upon such distribution if all amounts 
payable on or with respect to such shares were paid in full.

       (b)  After the payment of all preferential amounts required to be paid 
to the holders of Senior Preferred Stock, Series C Preferred Stock and any 
other class or series of stock



                                  -2-




of the Corporation ranking on liquidation on a parity with the Series C 
Preferred Stock, upon the dissolution, liquidation or winding up of the 
Corporation, the holders of shares of Junior Stock then outstanding shall be 
entitled to receive the remaining assets and funds of the Corporation 
available for distribution to its stockholders, in accordance with the terms 
of such Junior Stock.

       (c)  Any merger or consolidation of the Corporation or a subsidiary 
into or with another corporation or a sale of all or substantially all of the 
assets of the Corporation shall not be deemed to be a liquidation, 
dissolution or winding up of the Corporation for purposes of this Section 3.

    4. VOTING.

       (a)  Each holder of outstanding shares of Series C Preferred Stock 
shall be entitled to the number of votes equal to one-half the number of 
whole shares of Common Stock into which the shares of Series C Preferred 
Stock held by such holder are convertible (as adjusted from time to time 
pursuant to Section 5 hereof) as of the record date, at each meeting of 
stockholders of the Corporation (and written actions of stockholders in lieu 
of meetings) with respect to any and all matters presented to the 
stockholders of the Corporation for their action or consideration.  Except as 
provided by law or by the provisions of Subsections 3(b) or 3(c) below or by 
the provisions establishing any other series of stock, holders of Series C 
Preferred Stock and of any other outstanding series of stock shall vote 
together with the holders of Common Stock as a single class.

       (b)  The Corporation shall not amend, alter or repeal the preferences, 
special rights or other powers of the Series C Preferred Stock so as to 
affect adversely the Series C Preferred Stock, without the written consent or 
affirmative vote of the holders of a majority of the then outstanding shares 
of Series C Preferred Stock, given in writing or by vote at a meeting, 
consenting or voting (as the case may be) separately as a class.  For this 
purpose, without limiting the generality of the foregoing, the authorization 
of any shares of capital stock with preference or priority over the Series C 
Preferred Stock as to the right to receive either dividends or amounts 
distributable upon liquidation, dissolution



                                  -3-




or winding up of the Corporation shall be deemed to affect adversely the 
Series C Preferred Stock and the authorization of any shares of capital stock 
on a parity with Series C Preferred Stock as to the right to receive either 
dividends or amounts distributable upon liquidation, dissolution or winding 
up of the Corporation shall not be deemed to affect adversely the Series C 
Preferred Stock.

       (c)  So long as at least 251,226 shares of Series C Preferred Stock 
(subject to appropriate adjustment in the event of any dividend, stock split, 
combination or other similar recapitalization affecting such shares) are 
outstanding, the Corporation shall not, without the prior written consent of 
the holders of at least a majority of the then outstanding shares of Series C 
Preferred Stock, given in writing or by vote at a meeting, consenting or 
voting (as the case may be) separately as a class:  (i) take any action that 
would result in the holders of the Series C Preferred Stock becoming subject 
to taxation under Section 305 of the Internal Revenue Code of 1986, as 
amended; or (ii) declare or pay any dividends on capital stock (other than 
dividends payable solely in capital stock).

    5. OPTIONAL CONVERSION.  The holders of the Series C Preferred Stock 
shall have conversion rights as follows (the "Conversion Rights"):

       (a)  RIGHT TO CONVERT.  Each share of Series C Preferred Stock shall 
be convertible, at the option of the holder thereof, at any time and from 
time to time, and without the payment of additional consideration by the 
holder thereof, into such number of fully paid and nonassessable shares of 
Common Stock as is determined by dividing $9.9512 by the Conversion Price (as 
defined below) in effect at the time of conversion.  The "Conversion Price" 
shall initially be $2.4878.  Such Conversion Price, and the rate at which 
shares of Series C Preferred Stock may be converted into shares of Common 
Stock, shall be subject to adjustment as provided below.

    In the event of a notice of redemption of any shares of Series C 
Preferred Stock pursuant to Section 7 hereof, the Conversion Right of the 
shares designated for redemption shall terminate at the close of business on 
the fifth full day preceding the date fixed for redemption, unless the 
redemption price is not paid when due, in which case the Conversion Right for 
such shares shall continue until such price is paid in full.  In the event of 
a liquidation of the Corporation, the Conversion Right shall terminate at the 
close of business on the first full business day preceding the date fixed for 
the payment of any amounts distributable on liquidation to the holders of 
Series C Preferred Stock.




                                  -4-




       (b)  FRACTIONAL SHARES.  No fractional shares of Common Stock shall be 
issued upon conversion of the Series C Preferred Stock.  In lieu of any 
fractional shares to which the holder would otherwise be entitled, the 
Corporation shall pay cash equal to such fraction multiplied by the then 
effective Conversion Price.

       (c)  MECHANICS OF CONVERSION.

            (i)  In order for a holder of Series C Preferred Stock to convert 
shares of Series C Preferred Stock into shares of Common Stock, such holder 
shall surrender the certificate or certificates for such shares of Series C 
Preferred Stock, at the office of the transfer agent for the Series C 
Preferred Stock (or at the principal office of the Corporation if the 
Corporation serves as its own transfer agent), together with written notice 
that such holder elects to convert all or any number of the shares of the 
Series C Preferred Stock represented by such certificate or certificates.  
Such notice shall state such holder's name or the names of the nominees in 
which such holder wishes the certificate or certificates for shares of Common 
Stock to be issued.  If required by the Corporation, certificates surrendered 
for conversion shall be endorsed or accompanied by a written instrument or 
instruments of transfer, in form satisfactory to the Corporation, duly 
executed by the registered holder or his or its attorney duly authorized in 
writing.  The date of receipt of such certificates and notice by the transfer 
agent (or by the Corporation if the Corporation serves as its own transfer 
agent) shall be the conversion date ("Conversion Date").  The Corporation 
shall, as soon as practicable after the Conversion Date, issue and deliver at 
such office to such holder of Series C Preferred Stock, or to his or its 
nominees, a certificate or certificates for the number of shares of Common 
Stock to which such holder shall be entitled, together with cash in lieu of 
any fraction of a share.

            (ii) The Corporation shall at all times when the Series C 
Preferred Stock shall be outstanding, reserve and keep available out of its 
authorized but unissued stock, for the purpose of effecting the conversion of 
the Series C Preferred Stock, such number of its duly authorized shares of 
Common Stock as shall from time to time be sufficient to effect the 
conversion of all outstanding Series C Preferred Stock.  

            (iii) All shares of Series C Preferred Stock which shall have 
been surrendered for conversion as herein provided shall no longer be deemed 
to be outstanding and all



                                  -5-




rights with respect to such shares, including the rights, if any, to receive 
notices and to vote or to receive dividends, shall immediately cease and 
terminate on the Conversion Date.  Any shares of Series C Preferred Stock so 
converted shall be retired and cancelled and shall not be reissued, and the 
Corporation (without the need for stockholder action) may from time to time 
take such appropriate action as may be necessary to reduce the authorized 
number of shares of Series C Preferred Stock accordingly.

            (iv) The Corporation shall pay any and all issue and other taxes 
that may be payable in respect of any issuance or delivery of shares of 
Common Stock upon conversion of shares of Series C Preferred Stock pursuant 
to this Section 5.  The Corporation shall not, however, be required to pay 
any tax which may be payable in respect of any transfer involved in the 
issuance and delivery of shares of Common Stock in a name other than that in 
which the shares of Series C Preferred Stock so converted were registered, 
and no such issuance or delivery shall be made unless and until the person or 
entity requesting such issuance has paid to the Corporation the amount of any 
such tax or has established, to the satisfaction of the Corporation, that 
such tax has been paid.

       (d)  ADJUSTMENTS TO CONVERSION PRICE FOR DILUTING ISSUES:

            (i)  SPECIAL DEFINITIONS.  For purposes of this Subsection 5(d), 
the following definitions shall apply:

                 (A)  "OPTION" shall mean rights, options or warrants to 
subscribe for, purchase or otherwise acquire Common Stock or Convertible 
Securities.

                 (B)  "ORIGINAL ISSUE DATE" shall mean the date on which a 
share of Series C Preferred Stock was first issued.

                 (C)  "CONVERTIBLE SECURITIES" shall mean any evidences of 
indebtedness, shares or other securities directly or indirectly convertible 
into or exchangeable for Common Stock.

                 (D)  "ADDITIONAL SHARES OF COMMON STOCK" shall mean all 
shares of Common Stock issued (or, pursuant to Subsection 5(d)(iii) below, 
deemed to be issued) by the Corporation after the Original Issue Date, other 
than:



                                  -6-




                      (I)  shares of Common Stock issued or issuable by
                 reason of a dividend or other distribution on shares of Common
                 Stock that is covered by Subsection 5(e) or 5(f) below; or

                      (II) shares of Common Stock issued or issuable to 
                 employees or directors of, or consultants to, the 
                 Corporation pursuant to plans adopted by the Board of 
                 Directors of the Corporation. 

            (ii) NO ADJUSTMENT OF CONVERSION PRICE.  No adjustment in the 
number of shares of Common Stock into which the Series C Preferred Stock is 
convertible shall be made (a) unless the consideration per share (determined 
pursuant to Subsection 5(d)(v)) for an Additional Share of Common Stock 
issued or deemed to be issued by the Corporation is less than the applicable 
Conversion Price in effect on the date of, and immediately prior to, the 
issue of such Additional Shares, or (b) if the Corporation receives written 
notice from the holders of at least a majority of the then outstanding shares 
of Series C Preferred Stock, agreeing that no such adjustment shall be made 
as the result of such issuance of Additional Shares of Common Stock.

            (iii) ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES OF 
                  COMMON STOCK. 

    If the Corporation at any time or from time to time after the Original 
Issue Date shall issue any Options or Convertible Securities or shall fix a 
record date for the determination of holders of any class of securities 
entitled to receive any such Options or Convertible Securities, then the 
maximum number of shares of Common Stock (as set forth in the instrument 
relating thereto without regard to any provision contained therein for a 
subsequent adjustment of such number) issuable upon the exercise of such 
Options or, in the case of Convertible Securities and Options therefor, the 
conversion or exchange of such Convertible Securities, shall be deemed to be 
Additional Shares of Common Stock



                                  -7-




issued as of the time of such issue or, in case such a record date shall have 
been fixed, as of the close of business on such record date, provided that 
Additional Shares of Common Stock shall not be deemed to have been issued 
unless the consideration per share (determined pursuant to Subsection 5(d)(v) 
hereof) of such Additional Shares of Common Stock would be less than the 
applicable Conversion Price in effect on the date of and immediately prior to 
such issue, or such record date, as the case may be, and provided further 
that in any such case in which Additional Shares of Common Stock are deemed 
to be issued:

                 (A)  No further adjustment in the Conversion Price shall be 
made upon the subsequent issue of Convertible Securities or shares of Common 
Stock upon the exercise of such Options or conversion or exchange of such 
Convertible Securities;

                 (B)  If such Options or Convertible Securities by their 
terms provide, with the passage of time or otherwise, for any increase in the 
consideration payable to the Corporation, upon the exercise, conversion or 
exchange thereof, the Conversion Price computed upon the original issue 
thereof (or upon the occurrence of a record date with respect thereto), and 
any subsequent adjustments based thereon, shall, upon any such increase 
becoming effective, be recomputed to reflect such increase insofar as it 
affects such Options or the rights of conversion or exchange under such 
Convertible Securities;

                 (C)  Upon the expiration or termination of any unexercised 
Option, the Conversion Price shall not be readjusted, but the Additional 
Shares of Common Stock deemed issued as the result of the original issue of 
such Option shall not be deemed issued for the purposes of any subsequent 
adjustment of the Conversion Price;

                 (D)  In the event of any change in the number of shares of 
Common Stock issuable upon the exercise, conversion or exchange of any Option 
or Convertible Security, including, but not limited to, a change resulting 
from the anti-dilution provisions thereof, the Conversion Price then in 
effect shall forthwith be readjusted to such Conversion Price as would have 
obtained had the adjustment which was made upon the issuance of such Option 
or Convertible Security not exercised or converted prior to such change been 
made upon the basis of such change; and

                 (E)  No readjustment pursuant to clause (B) or (D) above 
shall have the effect of increasing the Conversion Price to an amount which 
exceeds the lower of (i) the Conversion Price on the original adjustment 
date, or (ii) the Conversion Price that would have resulted from any 
issuances of Additional



                                  -8-




Shares of Common Stock between the original adjustment date and such 
readjustment date.

    In the event the Corporation, after the Original Issue Date, amends any 
Options or Convertible Securities (whether such Options or Convertible 
Securities were outstanding on the Original Issue Date or were issued after 
the Original Issue Date) to increase the number of shares issuable thereunder 
or decrease the consideration to be paid upon exercise or conversion thereof, 
then such Options or Convertible Securities, as so amended, shall be deemed 
to have been issued after the Original Issue Date and the provisions of this 
Subsection 5(d)(iii) shall apply. 

            (iv) ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF ADDITIONAL 
                 SHARES OF COMMON STOCK.

    In the event the Corporation shall at any time after the Original Issue 
Date issue Additional Shares of Common Stock (including Additional Shares of 
Common Stock deemed to be issued pursuant to Subsection 5(d)(iii), but 
excluding shares issued as a stock split or combination as provided in 
Subsection 5(e) or upon a dividend or distribution as provided in Subsection 
5(f)), without consideration or for a consideration per share less than the 
applicable Conversion Price in effect on the date of and immediately prior to 
such issue, then and in such event, such Conversion Price shall be reduced, 
concurrently with such issue, to a price (calculated to the nearest cent) 
determined by multiplying such Conversion Price by a fraction, (A) the 
numerator of which shall be (1) the number of shares of Common Stock 
outstanding immediately prior to such issue plus (2) the number of shares of 
Common Stock which the aggregate consideration received or to be received by 
the Corporation for the total number of Additional Shares of Common Stock so 
issued would purchase at such Conversion Price; and (B) the denominator of 
which shall be the number of shares of Common Stock outstanding immediately 
prior to such issue plus the number of such Additional Shares of Common Stock 
so issued; PROVIDED THAT, (i) for the purpose of this Subsection 5(d)(iv), 
all shares of Common Stock issuable upon conversion or exercise of 
Convertible Securities or Options



                                  -9-




outstanding immediately prior to such issue shall be deemed to be 
outstanding, and (ii) for the purpose of this Subsection 5(d)(iv), the number 
of shares of Common Stock deemed issuable upon conversion or exercise of such 
outstanding Convertible Securities or Options shall not give effect to any 
adjustments to the conversion price or conversion rate or exercise price of 
such Convertible Securities or Options resulting from the issuance of 
Additional Shares of Common Stock that is the subject of this calculation.

            (v)  DETERMINATION OF CONSIDERATION.  For purposes of this 
Subsection 5(d), the consideration received by the Corporation for the issue 
of any Additional Shares of Common Stock shall be computed as follows:

                 (A)  CASH AND PROPERTY:  Such consideration shall:

                      (I)  insofar as it consists of cash, be computed at the 
aggregate of cash received by the Corporation, excluding amounts paid or 
payable for accrued interest;

                      (II) insofar as it consists of property other than 
cash, be computed at the fair market value thereof at the time of such issue, 
as determined in good faith by the Board of Directors; and

                      (III) in the event Additional Shares of Common Stock 
are issued together with other shares or securities or other assets of the 
Corporation for consideration which covers both, be the proportion of such 
consideration so received, computed as provided in clauses (I) and (II) 
above, as determined in good faith by the Board of Directors.

                 (B)  OPTIONS AND CONVERTIBLE SECURITIES.  The consideration 
per share received by the Corporation for Additional Shares of Common Stock 
deemed to have been issued pursuant to Subsection 5(d)(iii), relating to 
Options and Convertible Securities, shall be determined by dividing

            (x)  the total amount, if any, received or receivable by the 
Corporation as consideration for the issue of such Options or Convertible 
Securities, plus the minimum aggregate amount of additional consideration (as 
set forth in the instruments relating thereto, without regard to any 
provision contained therein for a subsequent adjustment of such 
consideration) payable to the Corporation upon the exercise of such Options 
or the conversion or exchange of such Convertible Securities, or in the case 
of Options for Convertible Securities, the exercise of such Options for 
Convertible Securities and the conversion or exchange of such Convertible 
Securities, by

            (y)  the maximum number of shares of Common Stock (as set forth 
in the instruments relating thereto,

                                  -10-




without regard to any provision contained therein for a subsequent adjustment 
of such number) issuable upon the exercise of such Options or the conversion 
or exchange of such Convertible Securities.

            (vi) MULTIPLE CLOSING DATES.  In the event the Corporation shall 
issue on more than one date Additional Shares of Common Stock which are 
comprised of shares of the same series or class of Convertible Securities, 
and such issuance dates occur within a period of no more than 120 days, then 
the Conversion Price shall be adjusted only once on account of such 
issuances, with such adjustment to occur upon the final such issuance and to 
give effect to all such issuances as if they occurred on the date of the 
final such issuance.

       (e)  ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS.  If the Corporation 
shall at any time or from time to time after the Original Issue Date effect a 
subdivision of the outstanding Common Stock, the Conversion Price then in 
effect immediately before that subdivision shall be proportionately 
decreased.  If the Corporation shall at any time or from time to time after 
the Original Issue Date combine the outstanding shares of Common Stock, the 
Conversion Price then in effect immediately before the combination shall be 
proportionately increased. Any adjustment under this paragraph shall become 
effective at the close of business on the date the subdivision or combination 
becomes effective.  

       (f)  ADJUSTMENT FOR CERTAIN DIVIDENDS AND DISTRIBUTIONS.  In the event 
the Corporation at any time, or from time to time after the Original Issue 
Date shall make or issue, or fix a record date for the determination of 
holders of Common Stock entitled to receive, a dividend or other distribution 
payable in additional shares of Common Stock, then and in each such event the 
Conversion Price for the Series C Preferred Stock then in effect shall be 
decreased as of the time of such issuance or, in the event such a record date 
shall have been fixed, as of the close of business on such record date, by 
multiplying the Conversion Price for the Series C Preferred Stock then in 
effect by a fraction:

            (1)  the numerator of which shall be the total number of shares 
       of Common Stock issued and outstanding immediately prior to the time 
       of such issuance or the close of business on such record date, and



                                  -11-




            (2)  the denominator of which shall be the total number of shares 
       of Common Stock issued and outstanding immediately prior to the time 
       of such issuance or the close of business on such record date plus the
       number of shares of Common Stock issuable in payment of such dividend
       or distribution;

provided, however, if such record date shall have been fixed and such 
dividend is not fully paid or if such distribution is not fully made on the 
date fixed therefor, the Conversion Price for the Series C Preferred Stock 
shall be recomputed accordingly as of the close of business on such record 
date and thereafter the Conversion Price for the Series C Preferred Stock 
shall be adjusted pursuant to this paragraph as of the time of actual payment 
of such dividends or distributions; and provided further, however, that no 
such adjustment shall be made if the holders of Series C Preferred Stock 
simultaneously receive a dividend or other distribution of shares of Common 
Stock in a number equal to the number of shares of Common Stock as they would 
have received if all outstanding shares of Series C Preferred Stock had been 
converted into Common Stock on the date of such event. 

       (g)  ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the event 
the Corporation at any time or from time to time after the Original Issue 
Date for the Series C Preferred Stock shall make or issue, or fix a record 
date for the determination of holders of Common Stock entitled to receive, a 
dividend or other distribution payable in securities of the Corporation other 
than shares of Common Stock, then and in each such event provision shall be 
made so that the holders of the Series C Preferred Stock shall receive upon 
conversion thereof in addition to the number of shares of Common Stock 
receivable thereupon, the amount of securities of the Corporation that they 
would have received had the Series C Preferred Stock been converted into 
Common Stock on the date of such event and had they thereafter, during the 
period from the date of such event to and including the conversion date, 
retained such securities receivable by them as aforesaid during such period, 
giving application to all adjustments called for during such period under 
this paragraph with respect to the rights of the holders of the Series C 
Preferred Stock; and provided further, however, that no such adjustment shall 
be made if the holders of Series C Preferred Stock simultaneously receive a 
dividend or other distribution of such securities in an amount equal to the 
amount of such securities as they would have received if all outstanding 
shares of Series C Preferred Stock had been converted into Common Stock on 
the date of such event. 



                                  -12-




       (h)  ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE, OR SUBSTITUTION.  If 
the Common Stock issuable upon the conversion of the Series C Preferred Stock 
shall be changed into the same or a different number of shares of any class 
or classes of stock, whether by capital reorganization, reclassification, or 
otherwise (other than a subdivision or combination of shares or stock 
dividend provided for above, or a reorganization, merger, consolidation, or 
sale of assets provided for below), then and in each such event the holder of 
each such share of Series C Preferred Stock shall have the right thereafter 
to convert such share into the kind and amount of shares of stock and other 
securities and property receivable, upon such reorganization, 
reclassification, or other change, by holders of the number of shares of 
Common Stock into which such shares of Series C Preferred Stock might have 
been converted immediately prior to such reorganization, reclassification, or 
change, all subject to further adjustment as provided herein.

       (i)  NO IMPAIRMENT.  The Corporation will not, by amendment of its 
Articles of Organization or through any reorganization, transfer of assets, 
consolidation, merger, dissolution, issue or sale of securities or any other 
voluntary action, avoid or seek to avoid the observance or performance of any 
of the terms to be observed or performed hereunder by the Corporation, but 
will at all times in good faith assist in the carrying out of all the 
provisions of this Section 5 and in the taking of all such action as may be 
necessary or appropriate in order to protect the Conversion Rights of the 
holders of the Series C Preferred Stock against impairment.

       (j)  CERTIFICATE AS TO ADJUSTMENTS.  Within 30 days after the 
occurrence of each adjustment or readjustment of the Conversion Price 
pursuant to this Section 5, the Corporation at its expense shall compute such 
adjustment or readjustment in accordance with the terms hereof and furnish to 
each holder of Series C Preferred Stock a certificate setting forth such 
adjustment or readjustment and showing in detail the facts upon which such 
adjustment or readjustment is based.  The Corporation shall, upon the written 
request at any time of any holder of Series C Preferred Stock, furnish or 
cause to be furnished to such holder a similar certificate setting forth (i) 
such adjustments and readjustments, (ii) the Conversion Price then in effect, 
and (iii) the number of shares of Common Stock and the amount, if any, of 
other property which then would be received upon the conversion of Series C 
Preferred Stock.



                                  -13-




        (k)  NOTICE OF RECORD DATE.  In the event:

             (i)  that the Corporation declares a dividend (or any other
        distribution) on its Common Stock payable in Common Stock or other
        securities of the Corporation;

             (ii) that the Corporation subdivides or combines its outstanding 
        shares of Common Stock;

             (iii) of any reclassification of the Common Stock of the 
       Corporation (other than a subdivision or combination of its outstanding 
       shares of Common Stock or a stock dividend or stock distribution 
       thereon), or of any consolidation or merger of the Corporation into or 
       with another corporation, or of the sale of all or substantially all 
       of the assets of the Corporation; or

             (iv) of the involuntary or voluntary dissolution, liquidation or 
       winding up of the Corporation;

then the Corporation shall mail to the holders of the Series C Preferred 
Stock at their last addresses as shown on the records of the Corporation, at 
least ten days prior to the date specified in (A) below or twenty days before 
the date specified in (B) below, a notice stating

       (A)  the record date of such dividend, distribution, subdivision or 
    combination, or, if a record is not to be taken, the date as of which the 
    holders of Common Stock of record to be entitled to such dividend,
    distribution, subdivision or combination are to be determined, or

       (B)  the date on which such reclassification, consolidation, merger, 
    sale, dissolution, liquidation or winding up is expected to become
    effective, and the date as of which it is expected that holders of Common
    Stock of record shall be entitled to exchange their shares of Common Stock
    for securities or other property deliverable upon



                                  -14-




    such reclassification, consolidation, merger, sale, dissolution or 
    winding up. 

    6. MANDATORY CONVERSION.

       (a)  Effective upon either of the following times (each a "Mandatory 
Conversion Time"), all outstanding shares of Series C Preferred Stock shall 
automatically be converted into shares of Common Stock, at the then effective 
conversion rate:

            (i)  Immediately prior to the consummation of any consolidation 
or merger of the Corporation with or into, or the sale of all or 
substantially all of the assets of the Corporation to, another corporation 
whose common stock is listed on the Nasdaq National Market or a national 
securities exchange; or

            (ii) Upon the close of business on the 20th trading day in any 
period of 20 consecutive trading days for which the volume-weighted average 
of the last reported sale prices per share of the Common Stock of the 
Corporation on the Nasdaq National Market, as reported by Nasdaq, is equal to 
or greater than $3.7317 (subject to appropriate adjustment for stock splits, 
stock dividends, combinations and other similar recapitalizations affecting 
such shares); provided that no such Mandatory Conversion Time shall be deemed 
to occur under this clause (ii) unless the Registration Statement (as defined 
in the Series C Preferred Stock Purchase Agreement between the Corporation 
and Lindner Investments dated October 14, 1996) is effective under the 
Securities Act of 1933, as amended, at all times during such 20-day period.   

       (b)  No later than 20 days prior to the Mandatory Conversion Time (in 
the case of a Mandatory Conversion Time under clause (i) above) or no later 
than 20 days after the Mandatory Conversion Time (in the case of a Mandatory 
Conversion Time under clause (ii) above), the Corporation shall deliver 
written notice of the Mandatory Conversion Time, and the conversion of the 
Series C Preferred Stock effected pursuant thereto, to all holders of record 
of shares of Series C Preferred Stock.  Such notice shall be sent by first 
class or registered mail, postage prepaid, to each record holder of Series C 
Preferred Stock at such holder's address last shown on the records of the 
transfer agent for the Series C Preferred Stock (or the records of the 
Corporation, if it serves as its own transfer agent).  Upon receipt of such 
notice, each holder of shares of Series C Preferred Stock shall promptly 
surrender his or its certificate or certificates for all such shares to the 
Corporation in



                                  -15-




accordance with the instructions set forth in such notice, and shall 
thereafter receive certificates for the number of shares of Common Stock to 
which such holder is entitled pursuant to this Section 6.  As of the 
Mandatory Conversion Time, all rights with respect to the Series C Preferred 
Stock so converted, including the rights, if any, to receive notices and vote 
(other than as a holder of Common Stock) will terminate, except only the 
rights of the holders thereof, upon surrender of their certificate or 
certificates therefor, to receive certificates for the number of shares of 
Common Stock into which such Series C Preferred Stock has been converted.  If 
so required by the Corporation, certificates surrendered for conversion shall 
be endorsed or accompanied by written instrument or instruments of transfer, 
in form satisfactory to the Corporation, duly executed by the registered 
holder or by his or its attorney duly authorized in writing.  As soon as 
practicable after the surrender of the certificate or certificates for Series 
C Preferred Stock, the Corporation shall cause to be issued and delivered to 
such holder, or on his or its written order, a certificate or certificates 
for the number of full shares of Common Stock issuable on such conversion in 
accordance with the provisions hereof and cash as provided in Subsection 5(b) 
in respect of any fraction of a share of Common Stock otherwise issuable upon 
such conversion.

       (c)  All certificates evidencing shares of Series C Preferred Stock 
which are required to be surrendered for conversion in accordance with the 
provisions hereof shall, from and after the Mandatory Conversion Time, be 
deemed to have been retired and cancelled and the shares of Series C 
Preferred Stock represented thereby converted into Common Stock for all 
purposes, notwithstanding the failure of the holder or holders thereof to 
surrender such certificates on or prior to such date.  Upon such mandatory 
conversion of the Series C Preferred Stock pursuant to this Section 6, all 
provisions hereof included under the caption "Series C Convertible Preferred 
Stock", and all references herein to the Series C Preferred Stock, shall be 
deleted and shall be of no further force or effect, and the Corporation may 
thereafter take such appropriate action (without the need for stockholder 
action) as may be necessary to give effect thereto.

    7. OPTIONAL REDEMPTION.

       (a)  At any time and from time to time on or after October 16, 1999, 
the Corporation may, at the option of its Board of Directors, redeem the 
Series C Preferred Stock, in whole or in part, for the following redemption 
prices per share (subject to



                                  -16-




appropriate adjustment for stock splits, stock dividends, combinations or 
other similar recapitalizations affecting such shares), plus any declared or 
accrued but unpaid dividends thereon to the Redemption Date (as defined 
below), which shall be payable in cash (hereinafter referred to as the 
"Redemption Price").

If the Redemption Date is

From October 16, 1999 through October 15, 2000     $12.43900
From October 16, 2000 through October 15, 2001     $11.94144
From October 16, 2001 through October 15, 2002     $11.44388
From October 16, 2002 through October 15, 2003     $10.94632
From October 16, 2003 through October 15, 2004     $10.44876
From and after October 16, 2004                    $ 9.9512

       (b)  In the event of any redemption of only a part of the then 
outstanding Series C Preferred Stock, the Corporation shall effect such 
redemption pro rata among the holders thereof based on the number of shares 
of Series C Preferred Stock held by such holders on the date of the 
Redemption Notice (as defined below).

       (c)  At least 30 days prior to the date fixed for any redemption of 
Series C Preferred Stock (hereinafter referred to as the "Redemption Date"), 
written notice shall be mailed, by first class or registered mail, postage 
prepaid, to each holder of record of Series C Preferred Stock to be redeemed, 
at his or its address last shown on the records of the transfer agent of the 
Series C Preferred Stock (or the records of the Corporation, if it serves as 
its own transfer agent), notifying such holder of the election of the 
Corporation to redeem such shares, specifying the Redemption Date and the 
time at which such holder's conversion rights (pursuant to Section 5 hereof) 
as to such shares terminate (which shall be the close of business on the 
fifth full day preceding the Redemption Date) and calling upon such holder to 
surrender to the Corporation, in the manner designated, his or its 
certificate or certificates representing the shares to be redeemed (such 
notice is hereinafter referred to as the "Redemption Notice").  On or prior 
to the Redemption Date, each holder of Series C Preferred Stock to be 
redeemed shall surrender his or its certificate or certificates representing 
such shares to the Corporation, in the manner designated in the Redemption 
Notice, and thereupon the Redemption Price of such shares shall be payable to 
the order of the person whose name appears on such certificate or 
certificates as the owner thereof and each surrendered certificate shall be 
cancelled.  In the



                                  -17-




event less than all the shares represented by any such certificate are 
redeemed, a new certificate shall be issued representing the unredeemed 
shares.  From and after the Redemption Date, unless there shall have been a 
default in payment of the Redemption Price, all rights of the holders of the 
Series C Preferred Stock designated for redemption in the Redemption Notice 
as holders of Series C Preferred Stock of the Corporation (except the right 
to receive the Redemption Price without interest upon surrender of their 
certificate or certificates) shall cease with respect to such shares, and 
such shares shall not thereafter be transferred on the books of the 
Corporation or be deemed to be outstanding for any purpose whatsoever.

       (d)  Any shares of Series C Preferred Stock so redeemed shall 
permanently be retired, shall no longer be deemed outstanding and shall not 
under any circumstances be reissued, and the Corporation may from time to 
time take such appropriate action as may be necessary to reduce the 
authorized Series C Preferred Stock accordingly.  Nothing herein contained 
shall prevent or restrict the purchase by the Corporation, from time to time 
either at public or private sale, of the whole or any part of the Series C 
Preferred Stock at such price or prices as the Corporation may determine, 
subject to the provisions of applicable law.

    8. WAIVER.  Any of the rights of the holders of Series C Preferred Stock 
set forth herein may be waived by the affirmative vote of the holders of more 
than fifty percent (50%) of the shares of Series C Preferred Stock then 
outstanding.
