the Class B Convertible Preferred Stock, Class C Convertible Preferred Stock,
the Class D Convertible Preferred Stock and at least forty percent (40%) of each
of the Class E Convertible Preferred Stock and the Class F Convertible Preferred

   8



Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible

                           5B. Notwithstanding any other provisions herein,

Preferred Stock, the Class C Convertible Preferred Stock, the Class D
Convertible Preferred Stock, the Class E Convertible Preferred Stock and the
Class F Convertible Preferred Stock, calculated on a class by class basis. As

securities. For any publicly traded securities, the value shall be deemed to be
the average of the closing prices or closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing of the Liquidity Event. If there is no active public market for the
securities, the value shall be the fair market value of such securities as
mutually determined by the Corporation and the holders of at least a majority of
the voting power of each class of the then outstanding shares of Convertible
Preferred Stock, voting on a class by class basis. In the event that no
agreement can be reached by the parties as to valuation of such consideration,
each of the Corporation and the holders of Convertible Preferred Stock shall
have three (3) days to designate in writing one person or entity, and such
designated persons shall have five (5) days to choose an independent appraiser,
who shall then, within five (5) days, make a determination as to the valuation
of consideration that shall be final and binding upon all parties. All costs
incurred as a result of such appraisal shall be borne by the Corporation;

                           5C. Amend, alter or repeal its Certificate of
Incorporation or By-Laws if the effect would be materially detrimental or
adverse in any manner with respect to the rights of the holders of the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock, the Class
D Convertible Preferred Stock, the Class E Convertible Preferred Stock and/or
the Class F Convertible Preferred Stock;

                           5D. Purchase or set aside any sums for the purchase
of, or pay any dividend or make any distribution on, any shares of stock other
than the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock, the Class E Convertible
Preferred Stock and the Class F Convertible Preferred Stock, except for (i)
Class A Accruing Dividends, (ii) dividends or other distributions payable on the
Common Stock solely in the form of additional shares of Common Stock, and (iii)
the purchase of shares of Common Stock from former employees of the Corporation
who acquired such shares directly from the Corporation, 



   9


if each such purchase is made pursuant to contractual rights held by the
Corporation relating to the termination of employment of such former employee
and the purchase price (except in the case of agreements executed prior to July
12, 1996) does not exceed the original issue price paid by such former employee
to the Corporation for such shares; or

                           5E. Redeem or otherwise acquire any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock, Class E Convertible Preferred Stock and Class F

holders of the shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock, Class E
Convertible Preferred Stock and Class F Convertible Preferred Stock.

                  VI. Conversions. The holders of shares of Preferred Stock
shall have the following conversion rights:

                           6A. Right to Convert. Subject to the terms and
conditions of this paragraph 6, the holder of any share or shares of Preferred
Stock shall have the right, at its option at any time, to convert any such
shares of Preferred Stock into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Preferred Stock so to be converted by the Original Purchase Price of such share
(which shall be $0.32 in the case of the Class A Convertible Preferred Stock,
$.76 in the case of Class B Convertible Preferred Stock, $1.44 in the case of
Class C Convertible Preferred Stock, $3.57 in the case of Class D Convertible
Preferred Stock, $4.93 in the case of Class E Convertible Preferred Stock and
$5.45 in the case of Class F Convertible Preferred Stock) and (ii) dividing the
result by the Original Purchase Price of such share or, in case an adjustment of
such price has taken place pursuant to the further provisions of this paragraph
6, then by the conversion price as last adjusted and in effect at the date any
share or shares of Preferred Stock are surrendered for conversion (such price,
or such price as last adjusted, being referred to as the "Conversion Price,"
with respect to the Class B Convertible Preferred Stock, the "Class B Conversion
Price," with respect to the Class C Convertible Preferred Stock, the "Class C
Conversion Price," with respect to the Class D Convertible Preferred Stock, the
"Class D Conversion Price," with respect to the Class E Convertible Preferred
Stock, the "Class E Conversion Price" and with respect to the Class F
Convertible Preferred Stock, the "Class F Conversion Price"). Such rights of
conversion shall be exercised by the holder thereof by giving written notice
that the holder elects to convert a stated number of shares of Preferred Stock
into Common Stock and by surrender of a certificate or certificates for the
shares so to be converted to the Corporation at its principal office (or such
other office or agency of the Corporation as the Corporation may designate by
notice in writing to the holders of the Preferred Stock) at any time during its
usual business hours on the date set forth in such notice, together with a
statement of the name or names (with address) in which the certificate or
certificates for shares of Common Stock shall be issued.




   10



                           6B. Issuance of Certificates; Time Conversion
Effected. Promptly after the receipt of the written notice referred to in
subparagraph 6A and surrender of the certificate or certificates for the share
or shares of Preferred Stock to be converted, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Preferred Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected and the Conversion Price shall
be determined as of the close of business on the date on which such written
notice shall have been received by the Corporation and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Preferred
Stock shall cease, and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

                           6C. Fractional Shares; Dividends; Partial Conversion.
No fractional shares shall be issued upon conversion of Preferred Stock into
Common Stock. No payment or adjustment shall be made for any cash dividends upon
the Common Stock issued as a result of a conversion. At the time of each
conversion, the Corporation shall pay in cash an amount equal to all dividends,
excluding Accruing Dividends, accrued and unpaid on the shares of Preferred
Stock surrendered for conversion to the date upon which such conversion is
deemed to take place as provided in subparagraph 6B. In case the number of
shares of Preferred Stock represented by the certificate or certificates
surrendered pursuant to subparagraph 6A exceeds the number of shares converted,
the Corporation shall, upon such conversion, execute and deliver to the holder,
at the expense of the Corporation, a new certificate or certificates for the
number of shares of Preferred Stock represented by the certificate or
certificates surrendered which are not to be converted. If any fractional share
of Common Stock would, except for the provisions of the first sentence of this
subparagraph 6C, be delivered upon such conversion, the Corporation, in lieu of
delivering such fractional share, shall pay to the holder surrendering the
Preferred Stock for conversion an amount in cash equal to the current market
price of such fractional share as determined in good faith by the Board of
Directors of the Corporation.

                           6D. Adjustment of Price Upon Issuance of Common
Stock. Except as provided in subparagraph 6E, if and whenever the Corporation
shall issue or sell, or is, in accordance with subparagraphs 6D(1) through
6D(7), deemed to have issued or sold, any shares of Common Stock for a
consideration per share less than (i) the Class B Conversion Price in effect
immediately prior to the time of such issue or sale, (ii) the Class C Conversion
Price in effect immediately prior to the time of such issue or sale, (iii) the
Class D Conversion Price in effect immediately prior to the time of such issue
or sale, (iv) the Class E Conversion Price in effect immediately prior to the
time of such issue or sale or (v) the Class F Conversion Price in effect
immediately prior to the time of such issue or sale, then, forthwith upon such
issue or sale, the Class B Conversion Price, the Class C Conversion Price, the
Class D Conversion Price, the Class E

   11



Conversion Price and/or the Class F Conversion Price, as the case may be, shall
be reduced to the price determined by dividing (i) an amount equal to the sum of
(a) the number of shares of Common Stock outstanding or deemed outstanding
immediately prior to such issue or sale multiplied by the then existing Class B
Conversion Price, the then existing Class C Conversion Price, the then existing
Class D Conversion Price, the then existing Class E Conversion Price or the then
existing Class F Conversion Price, as the case may be, and (b) the
consideration, if any, received by the Corporation upon such issue or sale, by
(ii) the total number of shares of Common Stock outstanding or deemed
outstanding immediately after such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                           6D(1) Issuance of Rights or Options. In case at any
time the Corporation shall in any manner grant (whether directly or by
assumption in a merger or otherwise) any warrants or other rights to subscribe
for or to purchase, or any options for the purchase of, Common Stock or any
stock or security convertible into or exchangeable for Common Stock (such
warrants, rights or options being called "Options" and such convertible or
exchangeable stock or securities being called "Convertible Securities") whether
or not such Options or the right to convert or exchange any such Convertible
Securities are immediately exercisable, and the price per share for which Common
Stock is issuable upon the exercise of such Options or upon the conversion or
exchange of such Convertible Securities (determined by dividing (i) the total
amount, if any, received or receivable by the Corporation as consideration for
the granting of such Options, plus the minimum aggregate amount of additional
consideration payable to the Corporation upon the exercise of all such Options,
plus, in the case of such Options which relate to Convertible Securities, the
minimum aggregate amount of additional consideration, if any, payable to the
Corporation upon the issue or sale of such Convertible Securities and upon the
conversion or exchange thereof, by (ii) the total maximum number of shares of
Common Stock issuable upon the exercise of such Options or upon the conversion
or exchange of all such Convertible Securities issuable upon the exercise of
such Options) shall be less than the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price, the Class E Conversion Price
and/or the Class F Conversion Price in effect immediately prior to the time of
the granting of such Options, then the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon conversion or exchange
of the total maximum amount of such Convertible Securities issuable upon the
exercise of such Options shall be deemed to have been issued for such price per
share as of the date of granting of such Options or the issuance of such
Convertible Securities and thereafter shall be deemed to be outstanding. Except
as otherwise provided in this subparagraph or in subparagraph 6D(3), no
adjustment of the Class B Conversion Price, the Class C Conversion Price, the
Class D Conversion Price, the Class E Conversion Price and/or the Class F
Conversion Price shall be made upon the actual issue of such Common Stock or of
such Convertible Securities upon exercise of such Options or upon the actual
issue of such Common Stock upon conversion or exchange of such Convertible
Securities.


   12



                           6D(2) Issuance of Convertible Securities. In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or other-wise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon
such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (ii) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the Class B Conversion Price, the Class C Conversion Price,
the Class D Conversion Price, the Class E Conversion Price and/or the Class F
Conversion Price in effect immediately prior to the time of such issue or sale,
then the total maximum number of shares of Common Stock issuable upon conversion
or exchange of all such Convertible Securities shall be deemed to have been
issued for such price per share as of the date of the issue or sale of such
Convertible Securities and thereafter shall be deemed to be outstanding,
provided that (a) except as otherwise provided in subparagraph 6D(3), no
adjustment of the Class B Conversion Price, the Class C Conversion Price, the
Class D Conversion Price, the Class E Conversion Price and/or the Class F
Conversion Price shall be made upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities and (b) if any such issue
or sale of such Convertible Securities is made upon exercise of any Options to
purchase any such Convertible Securities for which adjustments of the Class B
Conversion Price and/or the Class C Conversion Price and/or the Class D
Conversion Price and/or the Class E Conversion Price and/or the Class F
Conversion Price have been or are to be made pursuant to other provisions of
this subparagraph or subparagraph 6D, no further adjustment of the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price,
the Class E Conversion Price and/or the Class F Conversion Price shall be made
by reason of such issue or sale.

                           6D(3) Change in Option Price or Conversion Rate. Upon
the happening of any of the following events, namely, if the purchase price
provided for in any Option referred to in subparagraph 6D(1), the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate
at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are
convertible into or exchangeable for Common Stock shall change at any time
(other than changes under or by reason of provisions designed to protect against
dilution), the Class B Conversion Price, the Class C Conversion Price, the Class
D Conversion Price, the Class E Conversion Price and/or the Class F Conversion
Price in effect at the time of such event shall forthwith be readjusted to the
Class B Conversion Price, Class C Conversion Price, the Class D Conversion
Price, the Class E Conversion Price or the Class F Conversion Price, as the case
may be, which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold, but only if as a result of such
adjustment the Class B Conversion Price, the Class C Conversion 


   13



Price, the Class D Conversion Price, the Class E Conversion Price and/or the
Class F Conversion Price then in effect hereunder is thereby reduced; and on the
termination or expiration of any such Option or any such right to convert or
exchange such Convertible Securities, the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price, the Class E Conversion Price
and/or the Class F Conversion Price then in effect hereunder shall forthwith be
increased to the Class B Conversion Price, Class C Conversion Price, the Class D
Conversion Price, the Class E Conversion Price or Class F Conversion Price, as
the case may be, which would have been in effect at the time of such termination
or expiration had such Option or Convertible Securities, to the extent
outstanding immediately prior to such termination or expiration, never been
issued.

                           6D(4) Stock Dividends. In case the Corporation shall
declare a dividend or make any other distribution upon any stock of the
Corporation (other than the Common Stock) payable in Common Stock, Options or
Convertible Securities, then any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

                           6D(5) Consideration for Stock. In case any shares of
Common Stock, Options or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount
received by the Corporation therefor, without deduction therefrom of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Corporation in connection therewith. In case any shares of Common Stock,
Options or Convertible Securities shall be issued or sold for a consideration
other than cash, the amount of the consideration other than cash received by the
Corporation shall be deemed to be the fair value of such consideration as
determined in good faith by the Board of Directors of the Corporation, without
deduction of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case
any Options shall be issued in connection with the issue and sale of other
securities of the Corporation, together comprising one integral transaction in
which no specific consideration is allocated to such Options by the parties
thereto, such Options shall be deemed to have been issued for such consideration
as determined in good faith by the Board of Directors of the Corporation.

                           6D(6) Record Date. In case the Corporation shall take
a record of the holders of its Common Stock for the purpose of entitling them
(i) to receive a dividend or other distribution payable in Common Stock, Options
or Convertible Securities or (ii) to subscribe for or purchase Common Stock,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                           6D(7) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the


   14


account of the Corporation, and the disposition of any such shares shall be
considered an issue or sale of Common Stock for the purpose of this subparagraph
6D.

                           6E. Certain Issues of Common Stock Excepted. Anything
herein to the contrary notwithstanding, the Corporation shall not be required to
make any adjustment of the Class B Conversion Price, the Class C Conversion
Price, the Class D Conversion Price, the Class E Conversion Price or the Class F
Conversion Price in the case of the issuance from and after the date of filing
of these terms of the Preferred Stock of up to an aggregate of 2,100,000 shares
(appropriately adjusted to reflect the occurrence of any event described in
subparagraphs 6F or 6G) (the "Reserved Shares") of Common Stock to directors,
officers, employees or consultants of the Corporation in connection with their
service as directors of the Corporation, less the number of shares issued
pursuant to subscriptions, warrants, options, convertible securities, or other
rights outstanding on the date hereof, their employment by the Corporation or
their retention as consultants by the Corporation (provided that the number of
Reserved Shares may be increased with the approval of a majority of the Board of
Directors.

                           6F. Subdivision or Combination of Common Stock. In
case the Corporation shall at any time subdivide (by any stock split, stock
dividend, recapitalization or otherwise) its outstanding shares of Common Stock
into a greater number of shares, the Conversion Price in effect immediately
prior to such subdivision shall be proportionately reduced, and, conversely, in
case the outstanding shares of Common Stock shall be combined into a smaller
number of shares (by reverse stock split or otherwise), the Conversion Price in
effect immediately prior to such combination shall be proportionately increased.
In the case of any such subdivision, no further adjustment shall be made
pursuant to subparagraph 6D by reason thereof.

                           6G. Reorganization or Reclassification. If any
capital reorganization or reclassification of the capital stock of the
Corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a condition of such reorganization or
reclassification, lawful and adequate provisions shall be made whereby each
holder of a share or shares of Preferred Stock shall thereupon have the right to
receive, upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of Common Stock immediately theretofore receivable upon
the conversion of such share or shares of Preferred Stock, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of such Common Stock equal to the number of
shares of such Common Stock immediately theretofore receivable upon such
conversion had such reorganization or reclassification not taken place, and in
any such case appropriate provisions shall be made with respect to the rights
and interests of such holder to the end that the provisions hereof (including
without limitation provisions for adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise of such
conversion rights.



   15



                           6H. Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by delivery in person, certified or registered mail, return
receipt requested, telecopier or telex, addressed to each holder of shares of
Preferred Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the Conversion Price resulting from such
adjustment, setting forth in reasonable detail the method upon which such
calculation is based.

                           6I. Other Notices. In case at any time:

                                            (1) the Corporation shall declare
any dividend upon its Common Stock payable in cash or stock or make any other
distribution to the holders of its Common Stock;

                                            (2) the Corporation shall offer for
subscription pro rata to the holders of its Common Stock any additional shares
of stock of any class or other rights;

                                            (3) there shall be any capital
reorganization or reclassification of the capital stock of the Corporation, or a
consolidation or merger of the Corporation with or into another entity or
entities, or a sale, lease, abandonment, transfer or other disposition of all or
substantially all its assets; or

                                            (4) there shall be a voluntary or
involuntary dissolution, liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by delivery
in person, certified or registered mail, return receipt requested, telecopier or
telex, addressed to each holder of any shares of Preferred Stock at the address
of such holder as shown on the books of the Corporation, (a) at least 20 days'
prior written notice of the date on which the books of the Corporation shall
close or a record shall be taken for such dividend, distribution or subscription
rights or for deter-mining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, disposition, dissolution, liquidation or winding up, at
least 20 days' prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause (a) shall also specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto and such notice in
accordance with the foregoing clause (b) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up, as the case may be.

                           6J. Stock to be Reserved. The Corporation will at all
times reserve and keep available out of its authorized Common Stock, solely for
the purpose of issuance upon the conversion of Preferred Stock as herein
provided, such number of 


   16



shares of Common Stock as shall then be issuable upon the conversion of all
outstanding shares of Preferred Stock. The Corporation covenants that all shares
of Common Stock which shall be so issued shall be duly and validly issued and
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issue thereof, and, without limiting the generality of the
foregoing, the Corporation covenants that it will from time to time take all
such action as may be required to assure that the par value per share of the
Common Stock is at all times equal to or less than the Conversion Price in
effect at the time. The Corporation will take all such action as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Preferred Stock would exceed
the total number of shares of Common Stock then authorized by the Certificate of
Incorporation.

                           6K. Non-reissuance of Preferred Stock. Shares of
Preferred Stock which are converted into shares of Common Stock as provided
herein shall not be reissued.

                           6L. Issue Tax. The issuance of certificates for
shares of Common Stock upon conversion of Preferred Stock shall be made without
charge to the holders thereof for any issuance tax in respect thereof, provided
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Preferred Stock which
is being converted.

                           6M. Closing of Books. The Corporation will at no time
close its transfer books against the transfer of any Preferred Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Preferred Stock in any manner which interferes with the timely conversion of
such Preferred Stock, except as may otherwise be required to comply with
applicable securities laws.

                           6N. Definition of Common Stock. As used in this
paragraph 6, the term "Common Stock" shall mean and include the Corporation's
authorized Common Stock, par value $.001 per share, as constituted on the date
of filing of these terms of the Preferred Stock, and shall also include any
capital stock of any class of the Corporation thereafter authorized which shall
not be limited to a fixed sum or percentage in respect of the rights of the
holders thereof to participate in dividends or in the distribution of assets
upon the voluntary or involuntary liquidation, dissolution or winding up of the
Corporation; provided that the shares of Common Stock receivable upon conversion
of shares of Preferred Stock shall include only shares designated as Common
Stock of the Corporation on the date of filing of this instrument, or in case of
any reorganization or reclassification of the outstanding shares thereof, the
stock, securities or assets provided for in subparagraph 6G.


   17




                           6O. Mandatory Conversion. If at any time (i) the
Corporation shall effect a firm commitment underwritten public offering of
shares of Common Stock in which (A) the aggregate price paid for such shares by
the public shall be at least $30,000,000 and (B) the price paid by the public
for such shares shall be at least $7.00 per share (appropriately adjusted to
reflect the occurrence of any event described in subparagraph 6F), or (ii) a
Liquidity Event shall occur in which (a) the holders of shares of any class of
Preferred Stock would receive consideration for all of such shares (as if
converted to Common Stock) of at least $1.28 for (i) each share of Class A
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class A Convertible Preferred Stock is convertible; at least $3.04 for
(i) each share of Class B Convertible Preferred Stock or (ii) all shares of
Common Stock into which such share of Class B Convertible Preferred Stock is
convertible; at least $5.76 for (i) each share of Class C Convertible Preferred
Stock or (ii) all shares of Common Stock into which such share of Class C
Convertible Preferred Stock is convertible; at least $6.03 per share for (i)
each share of Class D Convertible Preferred Stock or (ii) all shares of Common
Stock into which such share of Class D Convertible Preferred Stock is
convertible; or at least $6.03 per share for (i) each share of Class E
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class E Convertible Preferred Stock is convertible; at least $6.03 per
share for (i) each share of Class F Convertible Preferred Stock or (ii) all
shares of Common Stock into which such share of Class F Convertible Preferred
Stock is convertible, then effective upon the closing of the sale of such shares
by the Corporation pursuant to such public offering or immediately prior to the
occurrence of such Liquidity Event, as the case may be, all outstanding shares
of Preferred Stock (in the case of a public offering) or such class of Preferred
Stock (in the case of a Liquidity Event) shall automatically convert to shares
of Common Stock on the basis set forth in this paragraph 6. Holders of shares of
Preferred Stock so converted may deliver to the Corporation at its principal
office (or such other office or agency of the Corporation as the Corporation may
designate by notice in writing to such holders) during its usual business hours,
the certificate or certificates for the shares so converted. As promptly as
practicable thereafter, the Corporation shall issue and deliver to such holder a
certificate or certificates for the number of whole shares of Common Stock to
which such holder is entitled, together with any cash dividends and payment in
lieu of fractional shares to which such holder may be entitled pursuant to
subparagraph 6C. Until such time as a holder of shares of Preferred Stock shall
surrender his or its certificates therefor as provided above, such certificates
shall be deemed to represent the shares of Common Stock to which such holder
shall be entitled upon the surrender thereof.

                  VII. Redemption. The shares of Class B Convertible Preferred
Stock, the Class C Convertible Preferred Stock, the Class D Convertible
Preferred Stock, the Class E Convertible Preferred Stock and the Class F
Convertible Preferred Stock shall be redeemed as follows:

                           7A. Mandatory Redemption. On September 11, 2002, and
on each of the next two anniversaries thereafter (the "Redemption Dates," and
each a "Redemption Date"), the Corporation shall redeem any outstanding shares

                                               11, 2004


                           7B. Redemption Price and Payment. The shares of Class
B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock, Class E Convertible Preferred Stock and Class F
Convertible Preferred Stock to be redeemed on any Redemption Date shall be
redeemed by paying for each share in cash an amount equal to $0.76, $1.44,
$3.57, $4.93 and $5.45 per share (appropriately adjusted to reflect the
occurrence of any event described in subparagraphs 6F or 6G), respectively,
plus, in the case of each share, an amount equal to all dividends, excluding
Accruing Dividends, declared but unpaid thereon, computed to such Redemption
Date, such amount being referred to as the "Redemption Price." Such payment
shall be made in full on the applicable Redemption Date to the holders entitled
thereto.

                           7C. Redemption Mechanics. At least 20 but not more
than 30 days prior to each Redemption Date, written notice (the "Redemption
Notice") shall be given by the Corporation by delivery in person, certified or
registered mail, return receipt requested, telecopier or telex, to each holder
of record (at the close of business on the business day next preceding the day
on which the Redemption Notice is given) of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock, Class E Convertible Preferred Stock and Class F Convertible
Preferred Stock notifying such holder of the redemption and specifying the
Redemption Price, such Redemption Date, the number of shares of Class B
Convertible 



   19



Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock, Class E Convertible Preferred Stock and/or Class F Convertible
Preferred Stock to be redeemed from such holder (computed on a pro rata basis in
accordance with the number of such shares held by all holders thereof) and the
place where said Redemption Price shall be payable. The Redemption Notice shall
be addressed to each holder at his address as shown by the records of the
Corporation. From and after the close of business on a Redemption Date, unless
there shall have been a default in the payment of the Redemption Price, all
rights of holders of shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock, Class E
Convertible Preferred Stock and Class F Convertible Preferred Stock (except the
right to receive the Redemption Price) shall cease with respect to the shares to
be redeemed on such Redemption Date, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever. If the funds of the Corporation legally available for
redemption of shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock, Class D Convertible Preferred Stock, Class E Convertible
Preferred Stock and Class F Convertible Preferred Stock on a Redemption Date are
insufficient to redeem the total number of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock, Class E Convertible Preferred Stock and Class F Convertible
Preferred Stock to be redeemed on such Redemption Date, the holders of such
shares shall share ratably in any funds legally available for redemption of such
shares according to the respective amounts which would be payable to them if the
full number of shares to be redeemed on such Redemption Date were actually
redeemed. The shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock, Class D Convertible Preferred Stock, Class E Convertible
Preferred Stock and Class F Convertible Preferred Stock required to be redeemed
but not so redeemed shall remain outstanding and entitled to all rights and
preferences provided herein. At any time thereafter when additional funds of the
Corporation are legally available for the redemption of such shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock, Class E Convertible Preferred Stock and Class F
Convertible Preferred Stock, such funds will be used, at the end of the next
succeeding fiscal quarter, to redeem the balance of such shares, or such portion
thereof for which funds are then legally available, on the basis set forth
above.

                           7D. Redeemed or Otherwise Acquired Shares to be
Retired. Any shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock, Class D Convertible Preferred Stock, Class E Convertible
Preferred Stock and Class F Convertible Preferred Stock redeemed pursuant to
this paragraph 7 or otherwise acquired by the Corporation in any manner
whatsoever shall be canceled and shall not under any circumstances be reissued;
and the Corporation may from time to time take such appropriate corporate action
as may be necessary to reduce accordingly the number of authorized shares of
Class B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class
D Convertible Preferred Stock, Class E Convertible Preferred Stock and Class F
Convertible Preferred Stock.



   20




                           7E. Delay of Redemption. Notwithstanding paragraph 7A
hereof, the Corporation shall not be required to redeem any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock, Class E Convertible Preferred Stock and Class F
Convertible Preferred Stock on any Redemption Date if the cost to the
Corporation of such redemption would be greater than one-half of the
Corporation's available average cash (including cash equivalents and to the
extent not prohibited by the Delaware General Corporate Law, marketable
securities) working capital balance for the quarter immediately preceding such
Redemption Date. If a redemption is delayed pursuant to this Paragraph 7E, the
Corporation shall redeem the shares to be so redeemed within 120 days of such
Redemption Date.

                  VIII Amendments. No provision of these terms of the Preferred
Stock may be amended, modified or waived without the written consent or
affirmative vote of the holders of at least two-thirds of the then outstanding
shares of Class B Convertible Preferred Stock and Class C Convertible Preferred
Stock and at least a majority of the then outstanding shares of Class D
Convertible Preferred Stock and at least forty percent (40%) of each of the
Class E Convertible Preferred Stock and the Class F Convertible Preferred Stock
then outstanding; provided, however, that so long as TTC Ventures holds at least
two percent (2%) of the outstanding shares of Common Stock of the
Corporation(assuming the conversion of all outstanding Preferred Stock), no
amendment shall be made to the provisions of Section 2C relating to the
representation of the holders of Class D Convertible Preferred Stock without the
consent of TTC Ventures and that so long as ADP holds at least two percent (2%)
of the outstanding shares of Common Stock of the Corporation (assuming the
conversion of all outstanding Preferred Stock), no amendment shall be made to
the provisions of the sixth sentence of Section 2C relating to the
representation of the holders of Class D Convertible Preferred Stock without the
consent of ADP; provided further, however, that so long as FBR holds at least
two percent (2%) of the outstanding shares of Common Stock of the Corporation
(assuming the conversion of all outstanding Preferred Stock), no amendment shall
be made to the provisions of Section 2D relating to the board observer rights of
the holders of Class E Convertible Preferred Stock without the consent of FBR
and, that so long as GECE and/or GEPT together or individually hold, in the
aggregate, at least 250,000 shares of the Class F Convertible Preferred Stock or
the amount of Common Stock into which such shares of Class F Convertible
Preferred Stock is convertible, no amendment shall be made to the provisions of
Section 2D relating to the board observer rights of the holders of Class F
Convertible Preferred Stock without the consent of GECE and GEPT.

Preferred Stock shall be insufficient to permit payment in full to the holders
of Class B Convertible Preferred Stock, Class C Convertible Preferred Stock,
Class D Convertible Preferred Stock and Class E Convertible Preferred Stock of
the Classes B, C, D and E Liquidation Preference Payments, then the entire
assets of the Corporation to be so distributed shall be distributed ratably, on

Class E Convertible Preferred Stock.

                           4B. Upon any liquidation, dissolution or winding up

stock ranking on liquidation junior to the Class A Convertible Preferred Stock,
to be paid an amount equal to $.32 per share plus, in the case of each share, an
amount equal to all Class A Accruing Dividends unpaid thereon (whether or not

payable with respect to one share of Class A Convertible Preferred Stock being

referred to as the "Class A Liquidation Preference Payments." The Class A

winding up of the Corporation, whether voluntary or involuntary, the assets to
be distributed among the holders of Class A Convertible Preferred Stock shall be
insufficient to permit payment in full to the holders of Class A Convertible
Preferred Stock of the Class A Liquidation Preference Payments, then the entire
remaining assets of the Corporation to be so distributed shall be distributed
ratably among the holders of Class A Convertible Preferred Stock.

                           4C. Upon any such liquidation, dissolution or winding

Preference Payments, the remaining net assets of the Corporation available for
distribution shall be distributed ratably among the holders of Preferred Stock
and Common Stock (with each share of Preferred Stock being deemed, for such
purpose, to be equal to the number of shares of Common Stock (including
fractions of a share) into which such share of Preferred Stock is convertible
immediately prior to the close of business on the business day fixed for such
distribution). Unless otherwise agreed by holders of at least two-thirds of the
Class B Convertible Preferred Stock and the Class C Convertible Preferred Stock,
each acting as a separate class, and a majority of the Class D Convertible
Preferred Stock and at least forty 


   26



percent (40%) of the Class E Convertible Preferred Stock then outstanding, each
acting as a separate class, the consolidation or merger of the Corporation into
or with any other entity or entities which results in the exchange of
outstanding shares of the Corporation for securities or other consideration
issued or paid or caused to be issued or paid by any such entity or affiliate
thereof (other than a merger to reincorporate the Corporation in a different
jurisdiction), and the sale, lease, abandonment, transfer or other disposition
by the Corporation of all or substantially all its assets (each such event a
"Liquidity Event"), shall be deemed to be a liquidation, dissolution or winding
up of the Corporation within the meaning of the provisions of this paragraph 4.

                           4D. Written notice of such liquidation, dissolution
or winding up, stating a payment date, the amount of the Liquidation Preference
Payments and the place where said Liquidation Preference Payments shall be
payable, shall be delivered in person, mailed by certified or registered mail,
return receipt requested, or sent by telecopier or telex, not less than 20 days
prior to the payment date stated therein, to the holders of record of Preferred
Stock, such notice to be addressed to each such holder at its address as shown
by the records of the Corporation. For purposes hereof, the Common Stock shall
rank on liquidation junior to the Class A Convertible Preferred Stock, the Class
B Convertible Preferred Stock, the Class C Convertible Preferred Stock, the
Class D Convertible Preferred Stock and the Class E Convertible Preferred Stock.

                  V. Restrictions. At any time when shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock are
outstanding, except where the vote or written consent of the holders of a
greater number of shares of the Corporation is required by law or by the
Certificate of Incorporation, and in addition to any other vote required by law
or the Certificate of Incorporation, without the approval of the holders of at
least a majority of the then outstanding shares of the Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, the Class D Convertible
Preferred Stock and at least forty percent (40%) of the Class E Convertible
Preferred Stock then outstanding, consenting or voting (as the case may be) as
separate classes, given in writing or by vote at a meeting, the Corporation will
not:

                           5A. Create or authorize the creation of any
additional class or series of shares of stock unless the same ranks junior to
the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible Stock
as to the distribution of assets on the liquidation, dissolution or winding up
of the Corporation, redemption and the payment of dividends, or increase the
authorized amount of the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock, the Class D Convertible Preferred Stock or the
Class E Convertible Preferred Stock or increase the authorized amount of any
additional class or series of shares of stock unless the same ranks junior to
the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible
Preferred Stock as to the distribution of assets on the liquidation, dissolution
or winding up of the Corporation, redemption and the payment of dividends, or
create or authorize any obligation or security convertible into shares of Class
B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock or the Class E Convertible Preferred Stock or into
shares of any 



   27



other class or series of stock unless the same ranks junior to the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock, the Class
D Convertible Preferred Stock and the Class E Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, whether any such creation,
authorization or increase shall be by means of amendment to the Certificate of
Incorporation or by merger, consolidation or otherwise; provided, that such
consent shall not be unreasonably withheld for the creation or issuance of an
additional class or series of shares ranking senior to the Class B Convertible
Preferred Stock, the Class C Convertible Preferred Stock, the Class D
Convertible Preferred Stock and the Class E Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends (a "Senior Security"), but
provided further, that if, within a reasonable time of the submission of a
proposal for the issuance of a Senior Security, information comes to light
indicating that such consent was withheld solely or primarily for the purpose of
negotiating the price of an additional investment by the holders of the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock, the Class
D Convertible Preferred Stock and/or the Class E Convertible Preferred Stock,
then such consent shall be deemed to have been unreasonably withheld for
purposes of this subparagraph 5A.

                           5B. Consent to any liquidation, dissolution or
winding up of the Corporation or consolidate or merge into or with any other
entity or entities or sell, lease, abandon, transfer or otherwise dispose of all
or substantially all its assets, unless such action would result in an
annualized return to the holders of the Class B Convertible Preferred Stock, the
Class C Convertible Preferred Stock, the Class D Convertible Preferred Stock and
the Class E Convertible Preferred Stock of at least 30%;

                           5C. Amend, alter or repeal its Certificate of
Incorporation or By-Laws if the effect would be materially detrimental or
adverse in any manner with respect to the rights of the holders of the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock, the Class
D Convertible Preferred Stock and/or the Class E Convertible Preferred Stock;

                           5D. Purchase or set aside any sums for the purchase
of, or pay any dividend or make any distribution on, any shares of stock other
than the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible
Preferred Stock, except for (i) Class A Accruing Dividends, (ii) dividends or
other distributions payable on the Common Stock solely in the form of additional
shares of Common Stock, and (iii) the purchase of shares of Common Stock from
former employees of the Corporation who acquired such shares directly from the
Corporation, if each such purchase is made pursuant to contractual rights held
by the Corporation relating to the termination of employment of such former
employee and the purchase price (except in the case of agreements executed prior
to July 12, 1996) does not exceed the original issue price paid by such former
employee to the Corporation for such shares; or

                           5E. Redeem or otherwise acquire any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock except as
expressly authorized in paragraph 7 hereof or pursuant to a purchase offer made
pro rata to all holders of the shares of Class B Convertible 



   28


Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock and Class E Convertible Preferred Stock on the basis of the
aggregate number of outstanding shares of Class B Convertible Preferred Stock,
Class C Convertible Preferred Stock, Class D Convertible Preferred Stock and/or
Class E Convertible Preferred Stock then held by each such holder.

                  VI. Conversions. The holders of shares of Preferred Stock
shall have the following conversion rights:

                           6A. Right to Convert. Subject to the terms and
conditions of this paragraph 6, the holder of any share or shares of Preferred
Stock shall have the right, at its option at any time, to convert any such
shares of Preferred Stock into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Preferred Stock so to be converted by the Original Purchase Price of such share
(which shall be $0.32 in the case of the Class A Convertible Preferred Stock,
$.76 in the case of Class B Convertible Preferred Stock, $1.44 in the case of
Class C Convertible Preferred Stock, $3.57 in the case of Class D Convertible
Preferred Stock and $4.93 in the case of Class E Convertible Preferred Stock)
and (ii) dividing the result by the conversion price of the Original Purchase
Price of such share or, in case an adjustment of such price has taken place
pursuant to the further provisions of this paragraph 6, then by the conversion
price as last adjusted and in effect at the date any share or shares of
Preferred Stock are surrendered for conversion (such price, or such price as
last adjusted, being referred to as the "Conversion Price," with respect to the
Class B Convertible Preferred Stock, the "Class B Conversion Price," with
respect to the Class C Convertible Preferred Stock, the "Class C Conversion
Price", with respect to the Class D Convertible Preferred Stock, the "Class D
Conversion Price" and with respect to the Class E Convertible Preferred Stock,
the "Class E Conversion Price"). Such rights of conversion shall be exercised by
the holder thereof by giving written notice that the holder elects to convert a
stated number of shares of Preferred Stock into Common Stock and by surrender of
a certificate or certificates for the shares so to be converted to the
Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holders
of the Preferred Stock) at any time during its usual business hours on the date
set forth in such notice, together with a statement of the name or names (with
address) in which the certificate or certificates for shares of Common Stock
shall be issued.

                           6B. Issuance of Certificates; Time Conversion
Effected. Promptly after the receipt of the written notice referred to in
subparagraph 6A and surrender of the certificate or certificates for the share
or shares of Preferred Stock to be converted, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Preferred Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected and the Conversion Price shall
be determined as of the close of business on the date on which such written
notice shall have been received by the Corporation and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Preferred
Stock shall cease, and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon


   29



such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

                           6C. Fractional Shares; Dividends; Partial Conversion.
No fractional shares shall be issued upon conversion of Preferred Stock into
Common Stock and no payment or adjustment shall be made upon any conversion on
account of any cash dividends on the Common Stock issued upon such conversion.
At the time of each conversion, the Corporation shall pay in cash an amount
equal to all dividends, excluding Accruing Dividends, accrued and unpaid on the
shares of Preferred Stock surrendered for conversion to the date upon which such
conversion is deemed to take place as provided in subparagraph 6B. In case the
number of shares of Preferred Stock represented by the certificate or
certificates surrendered pursuant to subparagraph 6A exceeds the number of
shares converted, the Corporation shall, upon such conversion, execute and
deliver to the holder, at the expense of the Corporation, a new certificate or
certificates for the number of shares of Preferred Stock represented by the
certificate or certificates surrendered which are not to be converted. If any
fractional share of Common Stock would, except for the provisions of the first
sentence of this subparagraph 6C, be delivered upon such conversion, the
Corporation, in lieu of delivering such fractional share, shall pay to the
holder surrendering the Preferred Stock for conversion an amount in cash equal
to the current market price of such fractional share as determined in good faith
by the Board of Directors of the Corporation.

                           6D. Adjustment of Price Upon Issuance of Common
Stock. Except as provided in subparagraph 6E, if and whenever the Corporation
shall issue or sell, or is, in accordance with subparagraphs 6D(1) through
6D(7), deemed to have issued or sold, any shares of Common Stock for a
consideration per share less than (i) the Class B Conversion Price in effect
immediately prior to the time of such issue or sale, (ii) the Class C Conversion
Price in effect immediately prior to the time of such issue or sale, (iii) the
Class D Conversion Price in effect immediately prior to the time of such issue
or sale, or (iv) the Class E Conversion Price in effect immediately prior to the
time of such issue or sale, then, forthwith upon such issue or sale, the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price, as the case may be, shall be reduced to the
price determined by dividing (i) an amount equal to the sum of (a) the number of
shares of Common Stock outstanding immediately prior to such issue or sale
multiplied by the then existing Class B Conversion Price, the then existing
Class C Conversion Price, the then existing Class D Conversion Price or the then
existing Class E Conversion Price, as the case may be, and (b) the
consideration, if any, received by the Corporation upon such issue or sale, by
(ii) the total number of shares of Common Stock outstanding immediately after
such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                           6D(1) Issuance of Rights or Options. In case at any
time the Corporation shall in any manner grant (whether directly or by
assumption in a merger or otherwise) any warrants or other rights to subscribe
for or to purchase, or any options for the purchase of, Common Stock or any
stock or security convertible into or exchangeable for Common Stock (such
warrants, rights or options being called "Options" and such convertible or



   30



exchangeable stock or securities being called "Convertible Securities") whether
or not such Options or the right to convert or exchange any such Convertible
Securities are immediately exercisable, and the price per share for which Common
Stock is issuable upon the exercise of such Options or upon the conversion or
exchange of such Convertible Securities (determined by dividing (i) the total
amount, if any, received or receivable by the Corporation as consideration for
the granting of such Options, plus the minimum aggregate amount of additional
consideration payable to the Corporation upon the exercise of all such Options,
plus, in the case of such Options which relate to Convertible Securities, the
minimum aggregate amount of additional consideration, if any, payable upon the
issue or sale of such Convertible Securities and upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Class B Conversion Price, the Class C Conversion Price, the Class D
Conversion Price and/or the Class E Conversion Price in effect immediately prior
to the time of the granting of such Options, then the total maximum number of
shares of Common Stock issuable upon the exercise of such Options or upon
conversion or exchange of the total maximum amount of such Convertible
Securities issuable upon the exercise of such Options shall be deemed to have
been issued for such price per share as of the date of granting of such Options
or the issuance of such Convertible Securities and thereafter shall be deemed to
be outstanding. Except as otherwise provided in subparagraph 6D(3), no
adjustment of the Class B Conversion Price, the Class C Conversion Price, the
Class D Conversion Price and/or the Class E Conversion Price shall be made upon
the actual issue of such Common Stock or of such Convertible Securities upon
exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

                           6D(2) Issuance of Convertible Securities. In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or other-wise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon
such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (ii) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the Class B Conversion Price, the Class C Conversion Price,
the Class D Conversion Price and/or the Class E Conversion Price in effect
immediately prior to the time of such issue or sale, then the total maxi-mum
number of shares of Common Stock issuable upon conversion or exchange of all
such Convertible Securities shall be deemed to have been issued for such price
per share as of the date of the issue or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding, provided that (a) except as
otherwise provided in subparagraph 6D(3), no adjustment of the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Convertible Securities and (b)
if any such issue or sale of such Convertible Securities is made upon exercise
of any Options to purchase any such Convertible Securities for which adjustments
of the Class B Conversion Price and/or the Class C Conversion Price and/or the
Class D Conversion Price 



   31



and/or the Class E Conversion Price have been or are to be made pursuant to
other provisions of this subparagraph 6D, no further adjustment of the Class B
Conversion Price, the Class C Conversion Price, The Class D Conversion Price
and/or the Class E Conversion Price shall be made by reason of such issue or
sale.

                           6D(3) Change in Option Price or Conversion Rate. Upon
the happening of any of the following events, namely, if the purchase price
provided for in any Option referred to in subparagraph 6D(1), the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate
at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are
convertible into or exchangeable for Common Stock shall change at any time
(including, but not limited to, changes under or by reason of provisions
designed to protect against dilution), the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price and/or the Class E Conversion
Price in effect at the time of such event shall forthwith be readjusted to the
Class B Conversion Price, Class C Conversion Price, the Class D Conversion Price
or the Class E Conversion Price, as the case may be, which would have been in
effect at such time had such Options or Convertible Securities still outstanding
provided for such changed purchase price, additional consideration or conversion
rate, as the case may be, at the time initially granted, issued or sold, but
only if as a result of such adjustment the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price and/or the Class E Conversion
Price then in effect hereunder is thereby reduced; and on the termination or
expiration of any such Option or any such right to convert or exchange such
Convertible Securities, the Class B Conversion Price, the Class C Conversion
Price, the Class D Conversion Price and/or the Class E Conversion Price then in
effect hereunder shall forthwith be increased to the Class B Conversion Price,
Class C Conversion Price, the Class D Conversion Price or Class E Conversion
Price, as the case may be, which would have been in effect at the time of such
termination or expiration had such Option or Convertible Securities, to the
extent outstanding immediately prior to such termination or expiration, never
been issued.

                           6D(4) Stock Dividends. In case the Corporation shall
declare a dividend or make any other distribution upon any stock of the
Corporation (other than the Common Stock) payable in Common Stock, Options or
Convertible Securities, then any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

                           6D(5) Consideration for Stock. In case any shares of
Common Stock, Options or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount
received by the Corporation therefor, without deduction therefrom of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Corporation in connection therewith. In case any shares of Common Stock,
Options or Convertible Securities shall be issued or sold for a consideration
other than cash, the amount of the consideration other than cash received by the
Corporation shall be deemed to be the fair value of such consideration as
determined in good faith by the Board of Directors of the Corporation, without
deduction of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case
any Options shall be issued in connection with the issue and sale of other
securities of the 




   32


Corporation, together comprising one integral transaction in which no specific
consideration is allocated to such Options by the parties thereto, such Options
shall be deemed to have been issued for such consideration as determined in good
faith by the Board of Directors of the Corporation.

                           6D(6) Record Date. In case the Corporation shall take
a record of the holders of its Common Stock for the purpose of entitling them
(i) to receive a dividend or other distribution payable in Common Stock, Options
or Convertible Securities or (ii) to subscribe for or purchase Common Stock,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                           6D(7) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Corporation, and the disposition of any such shares shall
be considered an issue or sale of Common Stock for the purpose of this
subparagraph 6D.

                           6E. Certain Issues of Common Stock Excepted. Anything
herein to the contrary notwithstanding, the Corporation shall not be required to
make any adjustment of the Class B Conversion Price, the Class C Conversion
Price, the Class D Conversion Price or the Class E Conversion Price in the case
of the issuance from and after the date of filing of these terms of the
Preferred Stock of up to an aggregate of 1,950,000 shares (appropriately
adjusted to reflect the occurrence of any event described in subparagraphs 6F or
6G) (the "Reserved Shares") of Common Stock to directors, officers, employees or
consultants of the Corporation in connection with their service as directors of
the Corporation, their employment by the Corporation or their retention as
consultants by the Corporation (provided that the number of Reserved Shares may
be increased (a) prior to December 31, 1998, with the approval of a majority of
the Board of Directors including the Class B Director, the Class C Director and
the Class D Directors and [(b) after December 31, 1998, with the approval of
either (i) a majority of the Board of Directors including the Class B Director,
the Class C Director and the Class D Directors or (ii) all directors other than
the Class B Director, the Class C Director and the Class D Directors), plus such
number of shares of Common Stock which are repurchased by the Corporation from
such persons after such date pursuant to contractual rights held by the
Corporation and at repurchase prices not exceeding the respective original
purchase prices paid by such persons to the Corporation therefor.

                           6F. Subdivision or Combination of Common Stock. In
case the Corporation shall at any time subdivide (by any stock split, stock
dividend or otherwise) its outstanding shares of Common Stock into a greater
number of shares, the Conversion Price in effect immediately prior to such
subdivision shall be proportionately reduced, and, conversely, in case the
outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased. In the case of any such subdivision, no
further adjustment shall be made pursuant to subparagraph 6D by reason thereof.



   33




                           6G. Reorganization or Reclassification. If any
capital reorganization or reclassification of the capital stock of the
Corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a condition of such reorganization or
reclassification, lawful and adequate provisions shall be made whereby each
holder of a share or shares of Preferred Stock shall thereupon have the right to
receive, upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of Common Stock immediately theretofore receivable upon
the conversion of such share or shares of Preferred Stock, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of such Common Stock equal to the number of
shares of such Common Stock immediately theretofore receivable upon such
conversion had such reorganization or reclassification not taken place, and in
any such case appropriate provisions shall be made with respect to the rights
and interests of such holder to the end that the provisions hereof (including
without limitation provisions for adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise of such
conversion rights.

                           6H. Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by delivery in person, certified or registered mail, return
receipt requested, telecopier or telex, addressed to each holder of shares of
Preferred Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the Conversion Price resulting from such
adjustment, setting forth in reasonable detail the method upon which such
calculation is based.

                           6I. Other Notices. In case at any time:

                                            (1) the Corporation shall declare
any dividend upon its Common Stock payable in cash or stock or make any other
distribution to the holders of its Common Stock;

                                            (2) the Corporation shall offer for
subscription pro rata to the holders of its Common Stock any additional shares
of stock of any class or other rights;

                                            (3) there shall be any capital
reorganization or reclassification of the capital stock of the Corporation, or a
consolidation or merger of the Corporation with or into another entity or
entities, or a sale, lease, abandonment, transfer or other disposition of all or
substantially all its assets; or

                                            (4) there shall be a voluntary or
involuntary dissolution, liquidation or winding up of the Corporation;

                           then, in any one or more of said cases, the
Corporation shall give, by delivery in person, certified or registered mail,
return receipt requested, telecopier or telex, addressed to each holder of any
shares of Preferred Stock at the address of such holder as shown on the books of
the Corporation, (a) at least 20 days' prior written notice of the date on which
the books of the Corporation shall close or a record shall be taken for such
dividend, distribution 



   34



or subscription rights or for deter-mining rights to vote in respect of any such
reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding up and (b) in the case of any such
reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding up, at least 20 days' prior written notice
of the date when the same shall take place. Such notice in accordance with the
foregoing clause (a) shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto and such notice in accordance with the foregoing
clause (b) shall also specify the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, disposition, dissolution, liquidation or winding up, as the case may be.

                           6J. Stock to be Reserved. The Corporation will at all
times reserve and keep available out of its authorized Common Stock, solely for
the purpose of issuance upon the conversion of Preferred Stock as herein
provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of all outstanding shares of Preferred Stock. The Corporation
covenants that all shares of Common Stock which shall be so issued shall be duly
and validly issued and fully paid and nonassessable and free from all taxes,
liens and charges with respect to the issue thereof, and, without limiting the
generality of the foregoing, the Corporation covenants that it will from time to
time take all such action as may be requisite to assure that the par value per
share of the Common Stock is at all times equal to or less than the Conversion
Price in effect at the time. The Corporation will take all such action as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Preferred Stock would exceed
the total number of shares of Common Stock then authorized by the Certificate of
Incorporation.

                           6K. Non-reissuance of Preferred Stock. Shares of
Preferred Stock which are converted into shares of Common Stock as provided
herein shall not be reissued.

                           6L. Issue Tax. The issuance of certificates for
shares of Common Stock upon conversion of Preferred Stock shall be made without
charge to the holders thereof for any issuance tax in respect thereof, provided
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Preferred Stock which
is being converted.

                           6M. Closing of Books. The Corporation will at no time
close its transfer books against the transfer of any Preferred Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Preferred Stock in any manner which interferes with the timely conversion of
such Preferred Stock, except as may otherwise be required to comply with
applicable securities laws.

                           6N. Definition of Common Stock. As used in this
paragraph 6, the term "Common Stock" shall mean and include the Corporation's
authorized Common Stock, par value


   35




$.001 per share, as constituted on the date of filing of these terms of the
Preferred Stock, and shall also include any capital stock of any class of the
Corporation thereafter authorized which shall not be limited to a fixed sum or
percentage in respect of the rights of the holders thereof to participate in
dividends or in the distribution of assets upon the voluntary or involuntary
liquidation, dissolution or winding up of the Corporation; provided that the
shares of Common Stock receivable upon conversion of shares of Preferred Stock
shall include only shares designated as Common Stock of the Corporation on the
date of filing of this instrument, or in case of any reorganization or
reclassification of the outstanding shares thereof, the stock, securities or
assets provided for in subparagraph 6G.

                           6O. Mandatory Conversion. If at any time (i) the
Corporation shall effect a firm commitment underwritten public offering of
shares of Common Stock in which (A) the aggregate price paid for such shares by
the public shall be at least $15,000,000 and (B) the price paid by the public
for such shares shall be at least $4.32 per share (appropriately adjusted to
reflect the occurrence of any event described in subparagraph 6F), or (ii) a
Liquidity Event shall occur in which (a) the holders of shares of any class of
Preferred Stock would receive consideration for all of such shares (as if
converted to Common Stock) of at least $1.28 for (i) each share of Class A
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class A Convertible Preferred Stock is convertible; at least $3.04 for
(i) each share of Class B Convertible Preferred Stock or (ii) all shares of
Common Stock into which such share of Class B Convertible Preferred Stock is
convertible; at least $5.76 for (i) each share of Class C Convertible Preferred
Stock or (ii) all shares of Common Stock into which such share of Class C
Convertible Preferred Stock is convertible; at least $6.03 per share for (i)
each share of Class D Convertible Preferred Stock or (ii) all shares of Common
Stock into which such share of Class D Convertible Preferred Stock is
convertible; or at least $6.03 per share for (i) each share of Class E
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class E Convertible Preferred Stock is convertible, then effective upon
the closing of the sale of such shares by the Corporation pursuant to such
public offering or immediately prior to the occurrence of such Liquidity Event,
as the case may be, all outstanding shares of Preferred Stock (in the case of a
public offering) or such class of Preferred Stock (in the case of a Liquidity
Event) shall automatically convert to shares of Common Stock on the basis set
forth in this paragraph 6. Holders of shares of Preferred Stock so converted may
deliver to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to such holders) during its usual business hours, the certificate or
certificates for the shares so converted. As promptly as practicable thereafter,
the Corporation shall issue and deliver to such holder a certificate or
certificates for the number of whole shares of Common Stock to which such holder
is entitled, together with any cash dividends and payment in lieu of fractional
shares to which such holder may be entitled pursuant to subparagraph 6C. Until
such time as a holder of shares of Preferred Stock shall surrender his or its
certificates therefor as provided above, such certificates shall be deemed to
represent the shares of Common Stock to which such holder shall be entitled upon
the surrender thereof.

                           VII. Redemption. The shares of Class B Convertible
Preferred Stock, the Class C Convertible Preferred Stock, the Class D
Convertible Preferred Stock and the Class E Convertible Preferred Stock shall be
redeemed as follows:



   36



                           7A. Mandatory Redemption. On September 11, 2002, and
on each of the next two anniversaries thereafter (the "Redemption Dates," and
each a "Redemption Date"), the Corporation shall redeem any outstanding shares
of Class B Convertible Preferred Stock, the Class C Convertible Preferred Stock,
the Class D Convertible Preferred Stock and the Class E Convertible Preferred

                           7B. Redemption Price and Payment. The shares of Class
B Convertible Preferred Stock, Class C Convertible Preferred Stock, the Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock to be
redeemed on any Redemption Date shall be redeemed by paying for each share in
cash an amount equal to $0.76, $1.44, $3.57 and $4.93 per share (appropriately
adjusted to reflect the occurrence of any event described in subparagraphs 6F or
6G), respectively, plus, in the case of each share, an amount equal to all
dividends, excluding Accruing Dividends, declared but unpaid thereon, computed
to such Redemption Date, such amount being referred to as the "Redemption
Price". Such payment shall be made in full on the applicable Redemption Date to
the holders entitled thereto.

                           7C. Redemption Mechanics. At least 20 but not more
than 30 days prior to each Redemption Date, written notice (the "Redemption
Notice") shall be given by the Corporation by delivery in person, certified or
registered mail, return receipt requested, telecopier or telex, to each holder
of record (at the close of business on the business day next preceding the day
on which the Redemption Notice is given) of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock and Class E Convertible Preferred Stock notifying such holder of
the redemption and specifying the Redemption Price, such Redemption Date, the
number of shares of Class B Convertible Preferred Stock, 



   37



Class C Convertible Preferred Stock, Class D Convertible Preferred Stock and/or
Class E Convertible Preferred Stock to be re-deemed from such holder (computed
on a pro rata basis in accordance with the number of such shares held by all
holders thereof) and the place where said Redemption Price shall be payable. The
Redemption Notice shall be addressed to each holder at his address as shown by
the records of the Corporation. From and after the close of business on a
Redemption Date, unless there shall have been a default in the payment of the
Redemption Price, all rights of holders of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, Class D Convertible
Preferred Stock and Class E Convertible Preferred Stock (except the right to
receive the Redemption Price) shall cease with respect to the shares to be
redeemed on such Redemption Date, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever. If the funds of the Corporation legally available for
redemption of shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock, Class D Convertible Preferred Stock and Class E Convertible
Preferred Stock on a Redemption Date are insufficient to redeem the total number
of shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock, Class D Convertible Preferred Stock and Class E Convertible Preferred
Stock to be redeemed on such Redemption Date, the holders of such shares shall
share ratably in any funds legally available for redemption of such shares
according to the respective amounts which would be payable to them if the full
number of shares to be redeemed on such Redemption Date were actually redeemed.
The shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock, Class D Convertible Preferred Stock and Class E Convertible Preferred
Stock required to be redeemed but not so redeemed shall remain outstanding and
entitled to all rights and preferences provided herein. At any time thereafter
when additional funds of the Corporation are legally available for the
redemption of such shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock and Class E
Convertible Preferred Stock, such funds will be used, at the end of the next
succeeding fiscal quarter, to redeem the balance of such shares, or such portion
thereof for which funds are then legally available, on the basis set forth
above.

                           7D. Redeemed or Otherwise Acquired Shares to be
Retired. Any shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock, Class D Convertible Preferred Stock and Class E Convertible
Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by
the Corporation in any manner whatsoever shall be canceled and shall not under
any circumstances be reissued; and the Corporation may from time to time take
such appropriate corporate action as may be necessary to reduce accordingly the
number of authorized shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock and Class E
Convertible Preferred Stock.

                           7E. Delay of Redemption. Notwithstanding paragraph 7A
hereof, the Corporation shall not be required to redeem any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock on any
Redemption Date if the cost to the Corporation of such redemption would be
greater than one-half of the Corporation's available average cash working



   38


capital balance for the quarter immediately preceding such Redemption Date. If a
redemption is delayed pursuant to this Paragraph 7E, the Corporation shall
redeem the shares to be so redeemed within 120 days of such Redemption Date.

                           VIII Amendments. No provision of these terms of the
Preferred Stock may be amended, modified or waived without the written consent
or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Class B Convertible Preferred Stock and Class C
Convertible Preferred Stock and at least a majority of the then outstanding
shares of Class D Convertible Preferred Stock and at least forty percent (40%)
of the Class E Convertible Preferred Stock then outstanding; provided, however,
that so long as TTC Ventures holds at least two percent (2%) of the outstanding
shares of Common Stock of the Corporation(assuming the conversion of all
outstanding Preferred Stock), no amendment shall be made to the provisions of
Section 2C relating to the representation of the holders of Class D Convertible
Preferred Stock without the consent of TTC Ventures and that so long as ADP
holds at least two percent (2%) of the outstanding shares of Common Stock of the
Corporation (assuming the conversion of all outstanding Preferred Stock), no
amendment shall be made to the provisions of the sixth sentence of Section 2C
relating to the representation of the holders of Class D Convertible Preferred
Stock without the consent of APD; PROVIDED FURTHER, HOWEVER, THAT SO LONG AS FBR
HOLDS AT LEAST TWO PERCENT (2%) OF THE OUTSTANDING SHARES OF COMMON STOCK OF THE
CORPORATION (ASSUMING THE CONVERSION OF ALL OUTSTANDING PREFERRED STOCK), NO
AMENDMENT SHALL BE MADE TO THE PROVISIONS OF SECTION 2C RELATING TO THE BOARD
OBSERVER RIGHTS OF THE HOLDERS OF CLASS E CONVERTIBLE PREFERRED STOCK WITHOUT
THE CONSENT OF FBR.

Preferred Stock shall have been paid in full their respective Liquidation
Preference Payments, the remaining net assets of the Corporation available for
distribution shall be distributed ratably among the holders of Preferred Stock
and Common Stock (with each share of Preferred Stock being deemed, for such
purpose, to be equal to the number of shares of Common Stock (including
fractions of a share) into which such share of Preferred Stock is convertible
immediately prior to the close of business on the business day fixed for such
distribution). Unless otherwise agreed by holders of at least two-thirds of the
Class B Convertible Preferred Stock and the Class C Convertible Preferred Stock,
each acting as a



   45



separate class, and a majority of the Class D Convertible Preferred Stock and at
least forty percent (40%) of the Class E Convertible Preferred Stock then
outstanding, each acting as a separate class, the consolidation or merger of the
Corporation into or with any other entity or entities which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by any such entity
or affiliate thereof (other than a merger to reincorporate the Corporation in a
different jurisdiction), and the sale, lease, abandonment, transfer or other
disposition by the Corporation of all or substantially all its assets (each such
event a "Liquidity Event"), shall be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of the provisions of this
paragraph 4.

                           4D. Written notice of such liquidation, dissolution
or winding up, stating a payment date, the amount of the Liquidation Preference
Payments and the place where said Liquidation Preference Payments shall be
payable, shall be delivered in person, mailed by certified or registered mail,
return receipt requested, or sent by telecopier or telex, not less than 20 days
prior to the payment date stated therein, to the holders of record of Preferred
Stock, such notice to be addressed to each such holder at its address as shown
by the records of the Corporation. For purposes hereof, the Common Stock shall
rank on liquidation junior to the Class A Convertible Preferred Stock, the Class
B Convertible Preferred Stock, the Class C Convertible Preferred Stock, the
Class D Convertible Preferred Stock and the Class E Convertible Preferred Stock.

                  V. Restrictions. At any time when shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock are
outstanding, except where the vote or written consent of the holders of a
greater number of shares of the Corporation is required by law or by the
Certificate of Incorporation, and in addition to any other vote required by law
or the Certificate of Incorporation, without the approval of the holders of at
least a majority of the then outstanding shares of the Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock, the Class D Convertible
Preferred Stock and at least forty percent (40%) of the Class E Convertible
Preferred Stock then outstanding, consenting or voting (as the case may be) as
separate classes, given in writing or by vote at a meeting, the Corporation will
not:

                           5A. Create or authorize the creation of any
additional class or series of shares of stock unless the same ranks junior to
the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible Stock
as to the distribution of assets on the liquidation, dissolution or winding up
of the Corporation, redemption and the payment of dividends, or increase the
authorized amount of the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock, the Class D Convertible Preferred Stock or the
Class E Convertible Preferred Stock or increase the authorized amount of any
additional class or series of shares of stock unless the same ranks junior to
the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible
Preferred Stock as to the distribution of assets on the liquidation, dissolution
or winding up of the Corporation, redemption and the payment of dividends, or
create or authorize any obligation or security convertible into shares of Class
B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D



   46



Convertible Preferred Stock or the Class E Convertible Preferred Stock or into
shares of any other class or series of stock unless the same ranks junior to the
Class B Convertible Preferred Stock, the Class C Convertible Preferred Stock,
the Class D Convertible Preferred Stock and the Class E Convertible Preferred
Stock as to the distribution of assets on the liquidation, dissolution or
winding up of the Corporation, redemption and the payment of dividends, whether
any such creation, authorization or increase shall be by means of amendment to
the Certificate of Incorporation or by merger, consolidation or otherwise;
provided, that such consent shall not be unreasonably withheld for the creation
or issuance of an additional class or series of shares ranking senior to the
Class B Convertible Preferred Stock, the Class C Convertible Preferred Stock,
the Class D Convertible Preferred Stock and the Class E Convertible Preferred
Stock as to the distribution of assets on the liquidation, dissolution or
winding up of the Corporation, redemption and the payment of dividends (a
"Senior Security"), but provided further, that if, within a reasonable time of
the submission of a proposal for the issuance of a Senior Security, information
comes to light indicating that such consent was withheld solely or primarily for
the purpose of negotiating the price of an additional investment by the holders
of the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and/or the Class E Convertible
Preferred Stock, then such consent shall be deemed to have been unreasonably
withheld for purposes of this subparagraph 5A.

                           5B. Consent to any liquidation, dissolution or
winding up of the Corporation or consolidate or merge into or with any other
entity or entities or sell, lease, abandon, transfer or otherwise dispose of all
or substantially all its assets, unless such action would result in an
annualized return to the holders of the Class B Convertible Preferred Stock, the
Class C Convertible Preferred Stock, the Class D Convertible Preferred Stock and
the Class E Convertible Preferred Stock of at least 30%;

                           5C. Amend, alter or repeal its Certificate of
Incorporation or By-Laws if the effect would be materially detrimental or
adverse in any manner with respect to the rights of the holders of the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock, the Class
D Convertible Preferred Stock and/or the Class E Convertible Preferred Stock;

                           5D. Purchase or set aside any sums for the purchase
of, or pay any dividend or make any distribution on, any shares of stock other
than the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock, the Class D Convertible Preferred Stock and the Class E Convertible
Preferred Stock, except for (i) Class A Accruing Dividends, (ii) dividends or
other distributions payable on the Common Stock solely in the form of additional
shares of Common Stock, and (iii) the purchase of shares of Common Stock from
former employees of the Corporation who acquired such shares directly from the
Corporation, if each such purchase is made pursuant to contractual rights held
by the Corporation relating to the termination of employment of such former
employee and the purchase price (except in the case of agreements executed prior
to July 12, 1996) does not exceed the original issue price paid by such former
employee to the Corporation for such shares; or

                           5E. Redeem or otherwise acquire any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock except as
expressly authorized in paragraph 7 hereof or 


   47


pursuant to a purchase offer made pro rata to all holders of the shares of Class
B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock on the basis
of the aggregate number of outstanding shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock, Class D Convertible Preferred Stock
and/or Class E Convertible Preferred Stock then held by each such holder.

                  VI. Conversions. The holders of shares of Preferred Stock
shall have the following conversion rights:

                           6A. Right to Convert. Subject to the terms and
conditions of this paragraph 6, the holder of any share or shares of Preferred
Stock shall have the right, at its option at any time, to convert any such
shares of Preferred Stock into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Preferred Stock so to be converted by the Original Purchase Price of such share
(which shall be $0.32 in the case of the Class A Convertible Preferred Stock,
$.76 in the case of Class B Convertible Preferred Stock, $1.44 in the case of
Class C Convertible Preferred Stock, $3.57 in the case of Class D Convertible
Preferred Stock and $4.93 in the case of Class E Convertible Preferred Stock)
and (ii) dividing the result by the conversion price of the Original Purchase
Price of such share or, in case an adjustment of such price has taken place
pursuant to the further provisions of this paragraph 6, then by the conversion
price as last adjusted and in effect at the date any share or shares of
Preferred Stock are surrendered for conversion (such price, or such price as
last adjusted, being referred to as the "Conversion Price," with respect to the
Class B Convertible Preferred Stock, the "Class B Conversion Price," with
respect to the Class C Convertible Preferred Stock, the "Class C Conversion
Price", with respect to the Class D Convertible Preferred Stock, the "Class D
Conversion Price" and with respect to the Class E Convertible Preferred Stock,
the "Class E Conversion Price"). Such rights of conversion shall be exercised by
the holder thereof by giving written notice that the holder elects to convert a
stated number of shares of Preferred Stock into Common Stock and by surrender of
a certificate or certificates for the shares so to be converted to the
Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holders
of the Preferred Stock) at any time during its usual business hours on the date
set forth in such notice, together with a statement of the name or names (with
address) in which the certificate or certificates for shares of Common Stock
shall be issued.

                           6B. Issuance of Certificates; Time Conversion
Effected. Promptly after the receipt of the written notice referred to in
subparagraph 6A and surrender of the certificate or certificates for the share
or shares of Preferred Stock to be converted, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Preferred Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected and the Conversion Price shall
be determined as of the close of business on the date on which such written
notice shall have been received by the Corporation and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Preferred
Stock shall cease, and the person or persons in whose 



   48



name or names any certificate or certificates for shares of Common Stock shall
be issuable upon such conversion shall be deemed to have become the holder or
holders of record of the shares represented thereby.

                           6C. Fractional Shares; Dividends; Partial Conversion.
No fractional shares shall be issued upon conversion of Preferred Stock into
Common Stock and no payment or adjustment shall be made upon any conversion on
account of any cash dividends on the Common Stock issued upon such conversion.
At the time of each conversion, the Corporation shall pay in cash an amount
equal to all dividends, excluding Accruing Dividends, accrued and unpaid on the
shares of Preferred Stock surrendered for conversion to the date upon which such
conversion is deemed to take place as provided in subparagraph 6B. In case the
number of shares of Preferred Stock represented by the certificate or
certificates surrendered pursuant to subparagraph 6A exceeds the number of
shares converted, the Corporation shall, upon such conversion, execute and
deliver to the holder, at the expense of the Corporation, a new certificate or
certificates for the number of shares of Preferred Stock represented by the
certificate or certificates surrendered which are not to be converted. If any
fractional share of Common Stock would, except for the provisions of the first
sentence of this subparagraph 6C, be delivered upon such conversion, the
Corporation, in lieu of delivering such fractional share, shall pay to the
holder surrendering the Preferred Stock for conversion an amount in cash equal
to the current market price of such fractional share as determined in good faith
by the Board of Directors of the Corporation.

                           6D. Adjustment of Price Upon Issuance of Common
Stock. Except as provided in subparagraph 6E, if and whenever the Corporation
shall issue or sell, or is, in accordance with subparagraphs 6D(1) through
6D(7), deemed to have issued or sold, any shares of Common Stock for a
consideration per share less than (i) the Class B Conversion Price in effect
immediately prior to the time of such issue or sale, (ii) the Class C Conversion
Price in effect immediately prior to the time of such issue or sale, (iii) the
Class D Conversion Price in effect immediately prior to the time of such issue
or sale, or (iv) the Class E Conversion Price in effect immediately prior to the
time of such issue or sale, then, forthwith upon such issue or sale, the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price, as the case may be, shall be reduced to the
price determined by dividing (i) an amount equal to the sum of (a) the number of
shares of Common Stock outstanding immediately prior to such issue or sale
multiplied by the then existing Class B Conversion Price, the then existing
Class C Conversion Price, the then existing Class D Conversion Price or the then
existing Class E Conversion Price, as the case may be, and (b) the
consideration, if any, received by the Corporation upon such issue or sale, by
(ii) the total number of shares of Common Stock outstanding immediately after
such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                           6D(1) Issuance of Rights or Options. In case at any
time the Corporation shall in any manner grant (whether directly or by
assumption in a merger or otherwise) any warrants or other rights to subscribe
for or to purchase, or any options for the purchase of, Common Stock or any
stock or security convertible into or exchangeable for 



   49



Common Stock (such warrants, rights or options being called "Options" and such
convertible or exchangeable stock or securities being called "Convertible
Securities") whether or not such Options or the right to convert or exchange any
such Convertible Securities are immediately exercisable, and the price per share
for which Common Stock is issuable upon the exercise of such Options or upon the
conversion or exchange of such Convertible Securities (determined by dividing
(i) the total amount, if any, received or receivable by the Corporation as
consideration for the granting of such Options, plus the minimum aggregate
amount of additional consideration payable to the Corporation upon the exercise
of all such Options, plus, in the case of such Options which relate to
Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof, by (ii) the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon the conversion or exchange of all such Convertible Securities
issuable upon the exercise of such Options) shall be less than the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price in effect immediately prior to the time of
the granting of such Options, then the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon conversion or exchange
of the total maximum amount of such Convertible Securities issuable upon the
exercise of such Options shall be deemed to have been issued for such price per
share as of the date of granting of such Options or the issuance of such
Convertible Securities and thereafter shall be deemed to be outstanding. Except
as otherwise provided in subparagraph 6D(3), no adjustment of the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price shall be made upon the actual issue of such
Common Stock or of such Convertible Securities upon exercise of such Options or
upon the actual issue of such Common Stock upon conversion or exchange of such
Convertible Securities.

                           6D(2) Issuance of Convertible Securities. In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or other-wise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon
such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (ii) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the Class B Conversion Price, the Class C Conversion Price,
the Class D Conversion Price and/or the Class E Conversion Price in effect
immediately prior to the time of such issue or sale, then the total maxi-mum
number of shares of Common Stock issuable upon conversion or exchange of all
such Convertible Securities shall be deemed to have been issued for such price
per share as of the date of the issue or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding, provided that (a) except as
otherwise provided in subparagraph 6D(3), no adjustment of the Class B
Conversion Price, the Class C Conversion Price, the Class D Conversion Price
and/or the Class E Conversion Price shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Convertible Securities and (b)
if any such issue or sale of such Convertible Securities is made upon exercise
of any Options to purchase any such Convertible Securities for which adjustments
of the Class B


   50



Conversion Price and/or the Class C Conversion Price and/or the Class D
Conversion Price and/or the Class E Conversion Price have been or are to be made
pursuant to other provisions of this subparagraph 6D, no further adjustment of
the Class B Conversion Price, the Class C Conversion Price, The Class D
Conversion Price and/or the Class E Conversion Price shall be made by reason of
such issue or sale.

                           6D(3) Change in Option Price or Conversion Rate. Upon
the happening of any of the following events, namely, if the purchase price
provided for in any Option referred to in subparagraph 6D(1), the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate
at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are
convertible into or exchangeable for Common Stock shall change at any time
(including, but not limited to, changes under or by reason of provisions
designed to protect against dilution), the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price and/or the Class E Conversion
Price in effect at the time of such event shall forthwith be readjusted to the
Class B Conversion Price, Class C Conversion Price, the Class D Conversion Price
or the Class E Conversion Price, as the case may be, which would have been in
effect at such time had such Options or Convertible Securities still outstanding
provided for such changed purchase price, additional consideration or conversion
rate, as the case may be, at the time initially granted, issued or sold, but
only if as a result of such adjustment the Class B Conversion Price, the Class C
Conversion Price, the Class D Conversion Price and/or the Class E Conversion
Price then in effect hereunder is thereby reduced; and on the termination or
expiration of any such Option or any such right to convert or exchange such
Convertible Securities, the Class B Conversion Price, the Class C Conversion
Price, the Class D Conversion Price and/or the Class E Conversion Price then in
effect hereunder shall forthwith be increased to the Class B Conversion Price,
Class C Conversion Price, the Class D Conversion Price or Class E Conversion
Price, as the case may be, which would have been in effect at the time of such
termination or expiration had such Option or Convertible Securities, to the
extent outstanding immediately prior to such termination or expiration, never
been issued.

                           6D(4) Stock Dividends. In case the Corporation shall
declare a dividend or make any other distribution upon any stock of the
Corporation (other than the Common Stock) payable in Common Stock, Options or
Convertible Securities, then any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

                           6D(5) Consideration for Stock. In case any shares of
Common Stock, Options or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount
received by the Corporation therefor, without deduction therefrom of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Corporation in connection therewith. In case any shares of Common Stock,
Options or Convertible Securities shall be issued or sold for a consideration
other than cash, the amount of the consideration other than cash received by the
Corporation shall be deemed to be the fair value of such consideration as
determined in good faith by the Board of Directors of the Corporation, without
deduction of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case



   51



any Options shall be issued in connection with the issue and sale of other
securities of the Corporation, together comprising one integral transaction in
which no specific consideration is allocated to such Options by the parties
thereto, such Options shall be deemed to have been issued for such consideration
as determined in good faith by the Board of Directors of the Corporation.

                           6D(6) Record Date. In case the Corporation shall take
a record of the holders of its Common Stock for the purpose of entitling them
(i) to receive a dividend or other distribution payable in Common Stock, Options
or Convertible Securities or (ii) to subscribe for or purchase Common Stock,
Options or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                           6D(7) Treasury Shares. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Corporation, and the disposition of any such shares shall
be considered an issue or sale of Common Stock for the purpose of this
subparagraph 6D.

                      6E. Certain Issues of Common Stock Excepted. Anything
herein to the contrary notwithstanding, the Corporation shall not be required to
make any adjustment of the Class B Conversion Price, the Class C Conversion
Price, the Class D Conversion Price or the Class E Conversion Price in the case
of the issuance from and after the date of filing of these terms of the
Preferred Stock of up to an aggregate of 1,950,000 shares (appropriately
adjusted to reflect the occurrence of any event described in subparagraphs 6F or
6G) (the "Reserved Shares") of Common Stock to directors, officers, employees or
consultants of the Corporation in connection with their service as directors of
the Corporation, their employment by the Corporation or their retention as
consultants by the Corporation (provided that the number of Reserved Shares may
be increased (a) prior to December 31, 1998, with the approval of a majority of
the Board of Directors including the Class B Director, the Class C Director and
the Class D Directors and [(b) after December 31, 1998,


   52



with the approval of either (i) a majority of the Board of Directors including
the Class B Director, the Class C Director and the Class D Directors or (ii) all
directors other than the Class B Director, the Class C Director and the Class D
Directors), plus such number of shares of Common Stock which are repurchased by
the Corporation from such persons after such date pursuant to contractual rights
held by the Corporation and at repurchase prices not exceeding the respective
original purchase prices paid by such persons to the Corporation therefor.

                      6F. Subdivision or Combination of Common Stock. In case
the Corporation shall at any time subdivide (by any stock split, stock dividend
or otherwise) its outstanding shares of Common Stock into a greater number of
shares, the Conversion Price in effect immediately prior to such subdivision
shall be proportionately reduced, and, conversely, in case the outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be


   53



proportionately increased. In the case of any such subdivision, no further
adjustment shall be made pursuant to subparagraph 6D by reason thereof.

                      6G. Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provisions shall be made whereby each holder of a share or shares
of Preferred Stock shall thereupon have the right to receive, upon the basis and
upon the terms and conditions specified herein and in lieu of the shares of
Common Stock immediately theretofore receivable upon the conversion of such
share or shares of Preferred Stock, such shares of stock, securities or assets
as may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
Common Stock immediately theretofore receivable upon such conversion had such
reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
such holder to the end that the provisions hereof (including without limitation
provisions for adjustments of the Conversion Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of such conversion rights.

                      6H. Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by delivery in person, certified or registered mail, return
receipt requested, telecopier or telex, addressed to each holder of shares of
Preferred Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the Conversion Price resulting from such
adjustment, setting forth in reasonable detail the method upon which such
calculation is based.

                      6I. Other Notices. In case at any time:

                                            (1) the Corporation shall declare
any dividend upon its Common Stock payable in cash or stock or make any other
distribution to the holders of its Common Stock;

                                            (2) the Corporation shall offer for
subscription pro rata to the holders of its Common Stock any additional shares
of stock of any class or other rights;

                                            (3) there shall be any capital
reorganization or reclassification of the capital stock of the Corporation, or a
consolidation or merger of the Corporation with or into another entity or
entities, or a sale, lease, abandonment, transfer or other disposition of all or
substantially all its assets; or

                                            (4) there shall be a voluntary or
involuntary dissolution, liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by delivery
in person, certified or registered mail, return receipt requested, telecopier or
telex, addressed to each holder


   54



of any shares of Preferred Stock at the address of such holder as shown on the
books of the Corporation, (a) at least 20 days' prior written notice of the date
on which the books of the Corporation shall close or a record shall be taken for
such dividend, distribution or subscription rights or for deter-mining rights to
vote in respect of any such reorganization, reclassification, consolidation,
merger, disposition, dissolution, liquidation or winding up and (b) in the case
of any such reorganization, reclassification, consolidation, merger,
disposition, dissolution, liquidation or winding up, at least 20 days' prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause (a) shall also specify, in the case of any
such dividend, distribution or subscription rights, the date on which the
holders of Common Stock shall be entitled thereto and such notice in accordance
with the foregoing clause (b) shall also specify the date on which the holders
of Common Stock shall be entitled to exchange their Common Stock for securities
or other property deliverable upon such reorganization, reclassification,
consolidation, merger, disposition, dissolution, liquidation or winding up, as
the case may be.

                      6J. Stock to be Reserved. The Corporation will at all
times reserve and keep available out of its authorized Common Stock, solely for
the purpose of issuance upon the conversion of Preferred Stock as herein
provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of all outstanding shares of Preferred Stock. The Corporation
covenants that all shares of Common Stock which shall be so issued shall be duly
and validly issued and fully paid and nonassessable and free from all taxes,
liens and charges with respect to the issue thereof, and, without limiting the
generality of the foregoing, the Corporation covenants that it will from time to
time take all such action as may be requisite to assure that the par value per
share of the Common Stock is at all times equal to or less than the Conversion
Price in effect at the time. The Corporation will take all such action as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Preferred Stock would exceed
the total number of shares of Common Stock then authorized by the Certificate of
Incorporation.

                      6K. Non-reissuance of Preferred Stock. Shares of Preferred
Stock which are converted into shares of Common Stock as provided herein shall
not be reissued.

                      6L. Issue Tax. The issuance of certificates for shares of
Common Stock upon conversion of Preferred Stock shall be made without charge to
the holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder of the Preferred Stock which is being
converted.

                      6M. Closing of Books. The Corporation will at no time
close its transfer books against the transfer of any Preferred Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Preferred Stock in any manner which interferes 


   55



with the timely conversion of such Preferred Stock, except as may otherwise be
required to comply with applicable securities laws.

                      6N. Definition of Common Stock. As used in this paragraph
6, the term "Common Stock" shall mean and include the Corporation's authorized
Common Stock, par value $.001 per share, as constituted on the date of filing of
these terms of the Preferred Stock, and shall also include any capital stock of
any class of the Corporation thereafter authorized which shall not be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends or in the distribution of assets upon the voluntary or
involuntary liquidation, dissolution or winding up of the Corporation; provided
that the shares of Common Stock receivable upon conversion of shares of
Preferred Stock shall include only shares designated as Common Stock of the
Corporation on the date of filing of this instrument, or in case of any
reorganization or reclassification of the outstanding shares thereof, the stock,
securities or assets provided for in subparagraph 6G.

                      6O. Mandatory Conversion. If at any time (i) the
Corporation shall effect a firm commitment underwritten public offering of
shares of Common Stock in which (A) the aggregate price paid for such shares by
the public shall be at least $15,000,000 and (B) the price paid by the public
for such shares shall be at least $4.32 per share (appropriately adjusted to
reflect the occurrence of any event described in subparagraph 6F), or (ii) a
Liquidity Event shall occur in which (a) the holders of shares of any class of
Preferred Stock would receive consideration for all of such shares (as if
converted to Common Stock) of at least $1.28 for (i) each share of Class A
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class A Convertible Preferred Stock is convertible; at least $3.04 for
(i) each share of Class B Convertible Preferred Stock or (ii) all shares of

convertible; or at least $6.03 per share for (i) each share of Class E
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class E Convertible Preferred Stock is convertible, then effective upon
the closing of the sale of such shares by the Corporation pursuant to such
public offering or immediately prior to the occurrence of such Liquidity Event,
as the case may be, all outstanding shares of Preferred Stock (in the case of a
public offering) or such class of Preferred Stock (in the case of a Liquidity
Event) shall automatically convert to shares of Common Stock on the basis set
forth in this paragraph 6. Holders of shares of Preferred Stock so converted may
deliver to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to such holders) during its usual business hours, the certificate or
certificates for the shares so converted. As promptly as practicable thereafter,
the Corporation shall issue and deliver to such holder a certificate or
certificates for the number of whole shares of Common Stock to which such holder
is entitled, together with any cash dividends and payment in lieu of fractional
shares to which such holder may be entitled pursuant to subparagraph 6C. Until
such time as a holder of shares of Preferred Stock shall surrender his or its
certificates therefor as provided above, such certificates shall be deemed to
represent the shares of Common Stock to which such holder shall be entitled upon
the surrender thereof.

                                               Stock, Class C Convertible Preferred Stock, Class D
                                               Convertible Preferred and Class E Convertible Preferred
                                               Stock outstanding on September 11, 2004


                      7B. Redemption Price and Payment. The shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, the Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock to be
redeemed on any Redemption Date shall be redeemed by paying for each share in
cash an amount equal to $0.76, $1.44, $3.57 and $4.93 per share (appropriately
adjusted to reflect the occurrence of any event described in subparagraphs 6F or
6G), respectively, plus, in the case of each share, an amount equal to all
dividends, excluding Accruing Dividends, declared but unpaid thereon, computed
to such Redemption Date, such amount being referred to as the "Redemption
Price". Such payment shall be made in full on the applicable Redemption Date to
the holders entitled thereto.

                      7C. Redemption Mechanics. At least 20 but not more than 30
days prior to each Redemption Date, written notice (the "Redemption Notice")
shall be given by the Corporation by delivery in person, certified or registered
mail, return receipt requested, telecopier or telex, to each holder of record
(at the close of business on the business day next preceding the day on which
the Redemption Notice is given) of shares of Class B Convertible Preferred


   57



Stock, Class C Convertible Preferred Stock, Class D Convertible Preferred Stock
and Class E Convertible Preferred Stock notifying such holder of the redemption
and specifying the Redemption Price, such Redemption Date, the number of shares
of Class B Convertible Preferred Stock, Class C Convertible Preferred Stock,
Class D Convertible Preferred Stock and/or Class E Convertible Preferred Stock
to be re-deemed from such holder (computed on a pro rata basis in accordance
with the number of such shares held by all holders thereof) and the place where
said Redemption Price shall be payable. The Redemption Notice shall be addressed
to each holder at his address as shown by the records of the Corporation. From
and after the close of business on a Redemption Date, unless there shall have
been a default in the payment of the Redemption Price, all rights of holders of
shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock, Class D Convertible Preferred Stock and Class E Convertible Preferred
Stock (except the right to receive the Redemption Price) shall cease with
respect to the shares to be redeemed on such Redemption Date, and such shares
shall not thereafter be transferred on the books of the Corporation or be deemed
to be outstanding for any purpose whatsoever. If the funds of the Corporation
legally available for redemption of shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock, Class D Convertible Preferred Stock
and Class E Convertible Preferred Stock on a Redemption Date are insufficient to
redeem the total number of shares of Class B Convertible Preferred Stock, Class
C Convertible Preferred Stock, Class D Convertible Preferred Stock and Class E
Convertible Preferred Stock to be redeemed on such Redemption Date, the holders
of such shares shall share ratably in any funds legally available for redemption
of such shares according to the respective amounts which would be payable to
them if the full number of shares to be redeemed on such Redemption Date were
actually redeemed. The shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock and Class E
Convertible Preferred Stock required to be redeemed but not so redeemed shall
remain outstanding and entitled to all rights and preferences provided herein.
At any time thereafter when additional funds of the Corporation are legally
available for the redemption of such shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock, Class D Convertible Preferred Stock
and Class E Convertible Preferred Stock, such funds will be used, at the end of
the next succeeding fiscal quarter, to redeem the balance of such shares, or
such portion thereof for which funds are then legally available, on the basis
set forth above.

                      7D. Redeemed or Otherwise Acquired Shares to be Retired.
Any shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock, Class D Convertible Preferred Stock and Class E Convertible Preferred
Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the
Corporation in any manner whatsoever shall be canceled and shall not under any
circumstances be reissued; and the Corporation may from time to time take such
appropriate corporate action as may be necessary to reduce accordingly the
number of authorized shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock, Class D Convertible Preferred Stock and Class E
Convertible Preferred Stock.

                      7E. Delay of Redemption. Notwithstanding paragraph 7A
hereof, the Corporation shall not be required to redeem any shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock, Class D
Convertible Preferred Stock and Class E Convertible Preferred Stock on any
Redemption Date if the cost to the Corporation of such redemption would be
greater than one-half of the Corporation's available average cash working


   58




capital balance for the quarter immediately preceding such Redemption Date. If a
redemption is delayed pursuant to this Paragraph 7E, the Corporation shall
redeem the shares to be so redeemed within 120 days of such Redemption Date.

                  VIII Amendments. No provision of these terms of the Preferred
Stock may be amended, modified or waived without the written consent or
affirmative vote of the holders of at least two-thirds of the then outstanding
shares of Class B Convertible Preferred Stock and Class C Convertible Preferred
Stock and at least a majority of the then outstanding shares of Class D
Convertible Preferred Stock and at least forty percent (40%) of the Class E
Convertible Preferred Stock then outstanding; provided, however, that so long as
TTC Ventures holds at least two percent (2%) of the outstanding shares of Common
Stock of the Corporation(assuming the conversion of all outstanding Preferred
Stock), no amendment shall be made to the provisions of Section 2C relating to
the representation of the holders of Class D Convertible Preferred Stock without
the consent of TTC Ventures and that so long as ADP holds at least two percent
(2%) of the outstanding shares of common stock of the corporation (assuming the
conversion of all outstanding preferred stock), no amendment shall be made to
the provisions of the sixth sentence of section 2c relating to the
representation of the holders of class d convertible preferred stock without the
consent of apd; PROVIDED FURTHER, HOWEVER, THAT SO LONG AS FBR HOLDS AT LEAST
TWO PERCENT (2%) OF THE OUTSTANDING SHARES OF COMMON STOCK OF THE CORPORATION
(ASSUMING THE CONVERSION OF ALL OUTSTANDING PREFERRED STOCK), NO AMENDMENT SHALL
BE MADE TO THE PROVISIONS OF SECTION 2C RELATING TO THE BOARD OBSERVER RIGHTS OF
THE HOLDERS OF CLASS E CONVERTIBLE PREFERRED STOCK WITHOUT THE CONSENT OF FBR.

as a single class on all actions to be taken by the stockholders of the
Corporation, including, but not limited to actions amending the Certificate of

Preferred Stock is then convertible.

                             b.     2B. Board Size.  The Corporation shall not,

majority of the shares of Class D Convertible Preferred Stock then outstanding
shall constitute a quorum of the Class D Convertible Preferred Stock for the
election of the director or directors to be elected solely by the holders of the
Class D Convertible Preferred Stock, the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Class C
Convertible Preferred Stock then outstanding shall constitute a quorum of the
Class C Convertible Preferred Stock for the election of the director to be

presence in person or by proxy (or the written consent) of the holders of a

         per share (the 'Class C Accruing Dividends"). The holders of the Class
         D Convertible Preferred Stock shall be entitled to receive, out of
         funds legally available therefor, (i) when and if declared by at least
         four members of the Board of Directors, or (ii) upon any liquidation,
         dissolution or winding up of the Corporation, quarterly dividends at
         the rate per annum of $0.2499 per share (the "Class D Accruing
         Dividends"). The Class A Accruing Dividends, the Class B Accruing
         Dividends, and the Class C Accruing Dividends and the Class D Accruing
         Dividends are sometimes referred to herein collectively as the
         "Accruing Dividends." Accruing Dividends shall accrue from day to day,
         whether or not earned or declared, and shall be cumulative. No dividend
         shall be paid on the Preferred Stock, other than Accruing Dividends, or
         on the Common Stock.



4.     Liquidation.



                             a.     4A.     Upon any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the holders of
the shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock shall first be entitled, before
any distribution or payment is made upon any stock ranking on liquidation junior
to the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock and the Class D Convertible Preferred Stock, to be paid an amount equal to
$0.76, $1.44 and $3.57 per share, respectively, plus, in the case of each share
of Class B Convertible Preferred Stock, an amount equal to all Class B Accruing
Dividends unpaid thereon (whether or not declared) and any other dividends
declared but unpaid thereon, in the case of each share of Class C convertible
Preferred Stock, an amount equal to all Class C Accruing Dividends unpaid
thereon (whether or not declared) and in the case of each share of Class D
Convertible Preferred Stock, an amount equal to all Class D Accruing Dividends
paid thereon (whether or not declared), and any other dividends declared but
unpaid thereon, computed to the date payment thereof is made available, such
amount payable with respect to one share of Class B Convertible Preferred Stock
being sometimes referred to as the "Class B 



   66


Liquidation Preference Payment," such amount payable with respect to one share
of Class C Convertible Preferred Stock being sometimes referred to as the "Class
C Liquidation Preference Payment," such amount payable with respect to one share
of Class D Convertible Preferred Stock being sometimes referred to as the "Class
D Liquidation Preference Payment", and with respect to all shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock and Class D
Convertible Preferred Stock being sometimes referred to as the "Class B, C and D
Liquidation Preference Payments." If upon such liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the assets to
be distributed among the holders of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock and Class D Convertible Preferred Stock shall be
insufficient to permit payment in full to the holders of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock of the Classes B, C and D Liquidation Preference Payments, then
the entire assets of the Corporation to be so distributed shall be distributed
ratably, on an as-converted basis, among the holders of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock.

                           b.       4B.     Upon any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, after the
holders of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock shall have been paid in full the
amounts to which they shall be entitled pursuant to paragraph 4A, the holders of
the shares of Class A. Convertible Preferred Stock shall then be entitled,
before any distribution or payment is made upon any stock ranking on liquidation
junior to the Class A Convertible Preferred Stock, to be paid an amount equal to
$.32 per share plus, in the case of each share, an amount equal to all Class A
Accruing Dividends unpaid thereon (whether or not declared) computed to the date
payment thereof is made available, such amount payable with respect to one share
of Class A convertible Preferred Stock being sometimes referred to as the "Class
A Liquidation Preference Payment" and with respect to all shares of Class A
Convertible Preferred Stock being sometimes referred to as the "Class A
Liquidation Preference Payments." The Class A Liquidation Preference Payments
and the Classes B, C and D Liquidation Preference Payments are sometimes
referred to herein collectively as the "Liquidation Preference Payments." If
upon such liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed among the holders of
Class A Convertible Preferred Stock shall be insufficient to permit payment in
full to the holders of Class A Convertible Preferred Stock of the Class A
Liquidation Preference Payments, then the entire remaining assets of the
Corporation to be so distributed shall be distributed ratably among the holders
of Class A Convertible Preferred Stock.

                           c.       4C.     Upon any such liquidation, 
dissolution or winding up of the corporation, immediately after the holders of
Class B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class
D Convertible Preferred Stock and Class A Convertible Preferred Stock shall have
been paid in full their respective Liquidation Preference Payments, the
remaining net assets of the Corporation available for 



   67



distribution shall be distributed ratably among the holders of Preferred Stock
and Common Stock (with each share of Preferred Stock being deemed, for such
purpose, to be equal to the number of shares of common Stock (including
fractions of a share) into which such share of Preferred Stock is convertible
immediately prior to the close of business on the business day fixed for such
distribution). Unless otherwise agreed by holders of at least two-thirds of the
Class B Convertible Preferred Stock and the Class C Convertible Preferred Stock,
each acting as a separate class, and a majority of the Class D Convertible
Preferred Stock, acting as a separate class, the consolidation or merger of the
Corporation into or with any other entity or entities which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by any such entity
or affiliate thereof (other than a merger to reincorporate the Corporation in a
different jurisdiction), and the sale, lease, abandonment, transfer or other
disposition by the Corporation of all or substantially all its assets (each such
event a "Liquidity Event"), shall be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of the provisions of this
paragraph 4.

                           d.       4D.     Written notice of such liquidation,
dissolution or winding up, stating a payment date, the amount of the Liquidation
preference Payments and the place where said Liquidation Preference Payments
shall be payable, shall be delivered in person, mailed by certified or
registered mail, return receipt requested, or sent by telecopier or telex, not
less than 20 days prior to the payment date stated therein, to the holders of
record of Preferred Stock, such notice to be addressed to each such holder at
its address as shown by the records of the Corporation. For purposes hereof, the
Common Stock shall rank on liquidation junior to the Class A Convertible
Preferred Stock, the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock.

  5.     Registrations.  At any time when shares of Class B Convertible 
         Preferred Stock, Class C Convertible Preferred Stock and Class D
         Convertible Preferred Stock are outstanding, except where the vote or
         written consent of the holders of a greater number of shares of the
         Corporation is required by law or by the Certificate of Incorporation,
         and in addition to any other vote required by law or the Certificate of
         Incorporation, without the approval of the holders of at least a
         majority of the then outstanding shares of the Class B Convertible
         Preferred Stock, Class C Convertible Preferred Stock and the Class D
         Convertible Preferred Stock, consenting or voting (as the case may be)
         as separate classes, given in writing or by vote at a meeting, the
         corporation will not:

                           a.       5A.     Create or authorize the creation of
any additional class or series of shares of stock unless the same ranks junior
to the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock and the Class D Convertible Preferred Stock as to the distribution of
assets on the liquidation, dissolution or winding up of the Corporation,
redemption and the payment of dividends, or increase the authorized amount of
the Class B Convertible Preferred Stock, the Class C Convertible 




   68


Preferred Stock or the Class D Convertible Preferred Stock or increase the
authorized amount of any additional class or series of shares of stock unless
the same ranks junior to the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, or create or authorize any
obligation or security convertible into shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock or Class D Convertible Preferred
Stock or into shares of any other class or series of stock unless the same ranks
junior to the Class B Convertible Preferred Stock, the Class C Convertible
Preferred Stock and the Class D Convertible Preferred Stock as to the
distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, whether any such creation,
authorization or increase shall be by means of amendment to the Certificate of
Incorporation or by merger, consolidation or otherwise; provided, that such
consent shall not be unreasonably withheld for the creation or issuance of an
additional class or series of shares ranking senior to the Class B Convertible
Preferred Stock, the Class C Convertible Preferred Stock and the Class D
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, redemption and the payment of
dividends (a "Senior Security"), but provided further, that if, within a
reasonable time of the submission of a proposal for the issuance of a Senior
Security, information comes to light indicating that such consent was withheld
solely or primarily for the purpose of negotiating the price of an additional
investment by the holders of the Class B Convertible Preferred Stock, the Class
C Convertible Preferred Stock and/or the Class D Convertible Preferred Stock,
then such consent shall be deemed to have been unreasonably withheld for
purposes of this subparagraph 5A.

                           b.       5B.     Consent to any liquidation, 
         dissolution or winding up of the Corporation or consolidate or merge
         into or with any other entity or entities or sell, lease, abandon,
         transfer or otherwise dispose of all or substantially all its assets,
         unless such action would result in an annualized return to the holders
         of the Class B Convertible Preferred Stock, the Class C Convertible
         Preferred Stock and the Class D Convertible Preferred Stock of at least
         30%;

                           c.       5C.     Amend, alter or repeal its 
Certificate of Incorporation or By-Laws if the effect would be materially
detrimental or adverse in any manner with respect to the rights of the holders
of the Class B convertible Preferred Stock, the Class C Convertible Preferred
Stock and/or the Class D Convertible Preferred Stock;

                           d.       5D.     Purchase or set aside any sums for 
the purchase of, or pay any dividend or make any distribution on, any shares of
stock other than the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock, except
for (i) Class A Accruing Dividends, (ii) dividends or other distributions
payable on the Common Stock solely in the form of additional shares of Common
Stock, and (iii) the purchase of shares of Common Stock from former employees of
the Corporation who acquired such shares directly from the Corporation, 


   69



if each such purchase is made pursuant to contractual rights held by the
Corporation relating to the termination of employment of such former employee
and the purchase price (except in the case of agreements executed prior to July
12, 1996) does not exceed the original issue price paid by such former employee
to the Corporation for such shares; or

                           e.       5E.     Redeem or otherwise acquire any 
shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock except as expressly authorized in
paragraph 7 hereof or pursuant to a purchase offer made pro rata to all holders
of the shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock on the basis of the
aggregate number of outstanding shares of Class B Convertible Preferred Stock,
Class C Convertible Preferred Stock and/or Class D Convertible Preferred Stock
then held by each such holder.

         Prior to the completion of the sale of up to 2,045,785 shares of Class
D Convertible Preferred Stock as set forth in the Class D Convertible Preferred
Stock Purchase Agreement, dated as of September 11, 1997, as amended, if a vote
concerning any of the matters set forth in this Section 5 results in a tie and
the results of such vote would equally affect each of the Class B Convertible
Preferred Stock, the Class C Convertible Preferred Stock and the Class D
Convertible Preferred Stock, the tie-breaking vote shall be cast by the Chief
Executive Officer of the Company. Upon the completion of such sale of the Class
D Convertible Preferred Stock, the provisions of this paragraph shall no longer
remain in effect.

6.     Conversions.  The holders of shares of Preferred Stock shall have the 
       following conversion rights:

                           a.       6A.     Right to Convert.  Subject to the 
terms and conditions of this paragraph 6, the holder of any share or shares of
Preferred Stock shall have the right, at its option at any time, to convert any
such shares of Preferred Stock into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Preferred Stock so to be converted by the Original Purchase Price of such share
(which shall be $0.32 in the case of the Class A convertible Preferred Stock,
$.76 in the case of Class B Convertible Preferred Stock, $1.44 in the case of
Class C Convertible Preferred Stock and $3.57 in the case of Class D Convertible
Preferred Stock) and (ii) dividing the result by the conversion price equal to
the Original Purchase Price of such share or, in case an adjustment of such
price has taken place pursuant to the further provisions of this paragraph 6,
then by the conversion price as last adjusted and in effect at the date any
share or shares of Preferred Stock are surrendered for conversion (such price,
or such price as last adjusted, being referred to as the "Conversion Price,"
with respect to the Class B Convertible Preferred Stock, the "Class B Conversion
Price," with respect to the Class C Convertible Preferred Stock, the "Class C
Conversion Price" and, with respect to the Class D Convertible Preferred Stock,
the "Class D Conversion Price"). Such rights of conversion shall be exercised by
the 


   70



holder thereof by giving written notice that the holder elects to convert a
stated number of shares of Preferred Stock into Common Stock and by surrender of
a certificate or certificates for the shares so to be converted to the
corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holders
of the Preferred Stock) at any time during its usual business hours on the date
set forth in such notice, together with a statement of the name or names (with
address) in which the certificate or certificates for shares of Common Stock
shall be issued.

                           b.       6B.     Issuance of Certificates; Time 
Conversion Effected. Promptly after the receipt of the written notice referred
to in subparagraph 6A and surrender of the certificate or certificates for the
share or shares of Preferred Stock to be converted, the Corporation shall issue
and deliver, or cause to be issued and delivered, to the holder, registered in
such name or names as such holder may direct, a certificate or certificates for
the number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Preferred Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected and the Conversion Price shall
be determined as of the close of business on the date on which such written
notice shall have been received by the Corporation and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Preferred
Stock shall cease, and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

                           c.       6C.     Fractional Shares; Dividends; 
Partial Conversion. No fractional shares shall be issued upon conversion of
Preferred Stock into Common Stock and no payment or adjustment shall be made
upon any conversion on account of any cash dividends on the Common Stock issued
upon such conversion. At the time of each conversion, the Corporation shall pay
in cash an amount equal to all dividends, excluding Accruing Dividends, accrued
and unpaid on the shares of Preferred Stock surrendered for conversion to the
date upon which such conversion is deemed to take place as provided in
subparagraph 6B. In case the number of shares of Preferred Stock represented by
the certificate or certificates surrendered pursuant to subparagraph 6A exceeds
the number of shares converted, the Corporation shall, upon such conversion,
execute and deliver to the holder, at the expense of the Corporation, a new
certificate or certificates for the number of shares of Preferred Stock
represented by the certificate or certificates surrendered which are not to be
converted. If any fractional share of Common Stock would, except for the
provisions of the first sentence of this subparagraph 6C, be delivered upon such
conversion, the Corporation, in lieu of delivering such fractional share, shall
pay to the holder surrendering the Preferred Stock for conversion an amount in
cash equal to the current market price of such fractional share as determined in
good faith by the Board of Directors of the Corporation.


   71




                           d.       6D.     Adjustment of Price Upon Issuance of
Common Stock. Except as provided in subparagraph 6E, if and whenever the
Corporation shall issue or sell, or is, in accordance with subparagraphs 6D(1)
through 6D(7), deemed to have issued or sold, any shares or Common Stock for a
consideration per share less than (i) the Class B Conversion Price in effect
immediately prior to the time of such issue or sale, (ii) the Class C Conversion
Price in effect immediately prior to the time of such issue or sale, or (iii)
the Class D Conversion Price in effect immediately prior to the time of such
issue or sale, then, forthwith upon such issue or sale, the Class B Conversion
Price, the Class C Conversion Price and/or the Class D Conversion Price, as the
case may be, shall be reduced to the price determined by dividing (i) an amount
equal to the sum of (a) the number of shares of Common Stock outstanding
immediately prior to such issue or sale multiplied by the then existing Class B
Conversion Price, the then existing Class C Conversion Price or the then
existing Class D Conversion Price, as the case may be, and (b) the
consideration, if any, received by the Corporation upon such issue or sale, by
(ii) the total number of shares of Common Stock outstanding immediately after
such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                                    i)      6D(1)    Issuance of Rights or 
Options. In case at any time the Corporation shall in any manner grant (whether
directly or by assumption in a merger or otherwise) any warrants or other rights
to subscribe for or to purchase, or any options for the purchase of, Common
Stock or any stock or security convertible into or exchangeable for Common Stock
(such warrants, rights or options being called "Options" and such convertible or
exchangeable stock or securities being called "Convertible Securities") whether
or not such Options or the right to convert or exchange any such Convertible
Securities are immediately exercisable, and the price per share for which Common
Stock is issuable upon the exercise of such Options or upon the conversion or
exchange of such Convertible Securities (determined by dividing (i) the total
amount, if any, received or receivable by the Corporation as consideration for
the granting of such Options, plus the minimum aggregate amount of additional
consideration payable to the Corporation upon the exercise of all such Options,
plus, in the case of such Options which relate to Convertible Securities, the
minimum aggregate amount of additional consideration, if any, payable upon the
issue or sale of such Convertible Securities and upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Class B Conversion Price, the Class C Conversion Price and/or the Class
D Conversion Price in effect immediately prior to the time of the granting of
such Options, then the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon conversion or exchange of the total
maximum amount of such Convertible Securities issuable upon the exercise of such
Options shall be deemed to have been for such price per share as of the date of
granting of such Options or the issuance of such Convertible Securities and
thereafter shall be deemed to be outstanding. Except as otherwise provided in
subparagraph 6D(3), no adjustment of the Class B Conversion Price, the Class C



   72




Conversion Price and/or the Class D Conversion Price shall be made upon the
actual issue of such Common Stock or of such Convertible Securities upon
exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

                                    ii)     6D(2)    Issuance of Convertible 
Securities. In case the Corporation shall in any manner issue (whether directly
or by assumption in a merger or otherwise) or sell any Convertible Securities,
whether or not the rights to exchange or convert any such Convertible Securities
are immediately exercisable, and the price per share for which Common Stock is
issuable upon such conversion or exchange (determined by dividing (i) the total
amount received or receivable by the Corporation as consideration for which the
issue or sale of such Convertible Securities, plus the minimum aggregate amount
of additional consideration, if any, payable to the Corporation upon the
conversion or exchange thereof, by (ii) the total maximum number of shares of
Common Stock issuable upon the conversion or exchange thereof, by (ii) the total
maximum number of shares of Common Stock issuable upon the conversion or
exchange of all such Convertible Securities) shall be less than the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price in effect immediately prior to the time of such issue or sale, then the
total maximum number of shares of Common Stock issuable upon conversion or
exchange of all such Convertible Securities shall be deemed to have been issued
for such price per share as of the date of the issue or sale of such Convertible
Securities and thereafter shall be deemed to be outstanding, provided that (a)
except as otherwise provided in subparagraph 6D(3), no adjustment of the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price shall be made upon the actual issue of such Common Stock upon conversion
or exchange of such Convertible Securities and (b) if any such issue or sale of
such Convertible Securities is made upon exercise of any Options to purchase any
such Convertible Securities for which adjustments of the Class B Conversion
Price and/or the Class C Conversion Price and/or the Class D Conversion Price
have been or are to be made pursuant to other provisions of this subparagraph
6D, no further adjustment of the Class B Conversion Price, the Class C
Conversion Price and/or the Class D Conversion Price shall be made by reason of
such issue or sale.

                                    iii)    6D(3)    Change in Option Price or 
Conversion Rate. Upon the happening of any of the following events, namely, if
the purchase price provided for in any Option referred to in subparagraph 6D(1),
the additional consideration, if any, payable upon the conversion or exchange of
any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the
rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2)
are convertible into or exchangeable for Common Stock shall change at any time
(including, but not limited to, changes under or by reason of provisions
designed to protect against dilution), the Class B Conversion Price, the Class C
Conversion Price and/or the Class D Conversion Price in effect at the time of
such event shall forthwith be readjusted to the Class B Conversion Price, Class
C Conversion Price or the Class D Conversion Price, as the case may be, which
would have been in effect at such time had such Options or Convertible
Securities still outstanding provided for such changed purchase price,
additional consideration or 



   73



conversion rate, as the case may be, at the time initially granted, issued or
sold, but only if as a result of such adjustment the Class B Conversion Price,
the Class C Conversion Price and/or the Class D Conversion Price then in effect
hereunder is thereby reduced; and on the termination or expiration of any such
Option or any such right to convert or exchange such Convertible Securities, the
Class B Conversion Price, the Class C Conversion Price and/or the Class D
Conversion Price then in effect hereunder shall forthwith be increased to the
Class B Conversion Price, Class C Conversion Price or Class D Conversion Price,
as the case may be, which would have been in effect at the time of such
termination or expiration had such Option or Convertible Securities, to the
extent outstanding immediately prior to such termination or expiration, never
been issued.

                                    iv)     6D(4)    Stock Dividends.  In case 
the Corporation shall declare a dividend or make any other distribution upon any
stock of the Corporation (other than the Common Stock) payable in Common Stock,
Options or Convertible Securities, then any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

                                    v)      6D(5) Consideration of Stock.  In 
case any shares of Common Stock, Options or Convertible Securities shall be
issued or sold for cash, the consideration received therefor shall be deemed to
be the amount received by the Corporation therefor, without deduction therefrom
of any expenses incurred or any underwriting commissions or concessions paid or
allowed by the Corporation in connection therewith. In case any shares of Common
Stock Options or Convertible Securities shall be issued or sold for a
consideration other than cash, the amount of the consideration other than cash
received by the Corporation shall be deemed to be the fair value of such
consideration as determined in good faith by the Board of Directors of the
Corporation, without deduction of any expenses incurred or any underwriting
commissions or concessions paid or allowed by the Corporation in connection
therewith. In case any Options shall be issued in connection with the issue and
sale of other securities of the Corporation, together comprising one integral
transaction in which no specific consideration is allocated to such Options by
the parties thereto, such Options shall be deemed to have been issued for such
consideration as determined in good faith by the Board of Directors of the
Corporation.

                                    vi)     6D(6)  Record Date.   In case the 
Corporation shall take a record of the holders of its Common Stock for the
purpose of entitling them (i) to receive a dividend or other distribution
payable in Common Stock, Options or Convertible Securities or (ii) to subscribe
for or purchase Common Stock, Options or Convertible Securities, then such
record date shall be deemed to be the date of the issue or sale of the shares of
Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of
such right of subscription or purchase, as the case may be.



   74




                                    vii)    6D(7)  Treasury Shares.  The number 
of shares of Common Stock outstanding at any given time shall not include shares
owned or held by or for the account of the Corporation, and the disposition of
any such shares shall be considered an issue or sale or Common Stock for the
purpose of this subparagraph 6D.

                           e.       6E.     Certain Issues of Common Stock 
Excepted. Anything herein to the contrary notwithstanding, the Corporation shall
not be required to make any adjustment of the Class B Conversion Price, the
Class C Conversion Price or the Class D Conversion Price in the case of the
issuance from and after the date of filing of these terms of the Preferred Stock
of up to an aggregate of 1,950,000 shares (appropriately adjusted to reflect the
occurrence of any event described in subparagraphs 6F or 6G) (the "Reserved
Shares") of Common Stock to directors, officers, employees or consultants of the
Corporation in connection with their service as directors of the Corporation,
their employment by the Corporation or their retention as consultants by the
Corporation (provided that the numbers of Reserved Shares may be increased (a)
prior to December 31, 1998, with the approval of a majority of the Board of
Directors including the Class B Director, the Class C Director, the Class D
Director and the Other Class D Director and (b) after December 31, 1998, with
the approval of either (i) a majority of the Board of Directors including the
Class B Director, the Class C Director, the Class D Director and the Other Class
D Director or (ii) all directors other than the Class B Director, the Class C
Director, the Class D Director and the Other Class D Director), plus such number
of shares of Common Stock which are repurchased by the Corporation from such
persons after such date pursuant to contractual rights held by the Corporation
and at repurchase prices not exceeding the respective original purchase price
paid by such persons to the Corporation therefor.

                           f.       6F.     Subdivision or Combination of Common
Stock. In case the corporation shall at any time subdivide (by any stock split,
stock dividend or otherwise) its outstanding shares of Common Stock into a
greater number of shares, the Conversion Price in effect immediately prior to
such subdivision shall be proportionately reduced, and, conversely, in case the
outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased. In the case of any such subdivision, no
further adjustment shall be made pursuant to subparagraph 6D by reason thereof.

                           g.       6G.     Reorganization or Reclassification. 
If any capital reorganization or reclassification of the capital stock of the
Corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then as a condition of such reorganization or
reclassification, lawful and adequate provisions shall be made whereby each
holder of a share or shares of Preferred Stock shall thereupon have the right to
receive, upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of common Stock immediately theretofore receivable upon
the conversion of such share or shares of Preferred Stock, such shares of stock,
securities or assets as 


   75



may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
Common Stock immediately theretofore receivable upon such conversion had such
reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
such holder to the end that the provisions hereof (including without limitation
provisions for adjustments of the Conversions Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of such conversion rights.

                           h.       6H.     Notice of Adjustment.  Upon any 
adjustment of the Conversion Price, then and in each such case the Corporation
shall give written notice thereof, by delivery in person, certified or
registered mail, return receipt requested, telecopier or telex, addressed to
each holder of shares or Preferred Stock at the address of such holder as shown
on the books of the Corporation, which notice shall state the Conversion Price
resulting from such adjustment, setting forth in reasonable detail the method
upon which such calculation is based.

                           i.       6I.     Other Notices.  In case at any time:

                                            (1)      the Corporation shall 
declare any dividend upon its Common Stock payable in cash or stock or make any
other distribution to the holders of its Common Stock;

                                            (2)      the Corporation shall offer
for subscription pro rata to the holders of its Common Stock any additional
shares for stock of any class or other rights;

                                            (3)      there shall be any equal 
reorganization or reclassification of the capital stock of the Corporation, or a
consideration or merger of the Corporation with or into another equity or
entities; or a sale, lease, abandonment, transfer or other disposition of all or
substantially all its assets; or

                                            (4)      there shall be a voluntary 
or involuntary dissolution, liquidation or winding up of the Corporation;

 then, in any one or more of said cases, the Corporation shall give, by delivery
in person, certified or registered mail, return receipt requested, telecopier or
telex, addressed to each holder or any shares of Preferred Stock at the address
of such holder as shown on the books of the Corporation, (a) at least 20 days'
prior written notice of the date on which the books of the Corporation shall
close or record shall be taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, disposition, dissolution, liquidation or winding



   76



up, at least 20 days' prior written notice of the date when the same shall take
place. Such notice in accordance with the foregoing clause (a) shall also
specify, in the case of any such dividend, distribution or subscription rights,
the date on which the holders of Common Stock shall be entitled thereto and such
notice in accordance with the foregoing clause (b) shall also specify the date
on which the holders of Common Stock shall be entitled to exchange their Common
Stock for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up, as the case may be.

                           J.       6J.     Stock to be Reserved.  The 
Corporation will at all times reserve and keep available out of its authorized
Common Stock, solely for the purpose of issuance upon the conversion of
Preferred Stock as herein provided, such number of shares of Common Stock as
shall then be issuable upon the conversion of all outstanding shares of
Preferred Stock. The Corporation covenants that all shares of Common Stock which
shall be so issued shall be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and without limiting the generality of the foregoing, the
Corporation covenants that it will from time to time take all such action as may
be requisite to assure that the par value per share of the Common Stock is at
all times equal to or less than the Conversion Price in effect at the time. The
Corporation will take all such action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable
law or regulation, or of any requirement of any national securities exchange
upon which the Common Stock may be listed. The Corporation will not take any
action which results in any adjustment of the Conversion Price if the total
number of shares of Common Stock issued and issuable after such action upon
conversion of the Preferred Stock would exceed the total number of shares of
Common Stock then authorized by the Certificate of Incorporation.

                           K.       6K.     Non Reissuance of Preferred Stock. 
Shares of Preferred Stock which are converted into shares of Common Stock as
provided herein shall not be reissued.

                           L.       6L.     Issue Tax.  The issuance of 
certificates for shares of Common Stock upon conversion of Preferred Stock shall
be made without charge to the holders thereof for any issuance tax in respect
thereof, provided that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance and
delivery of any certificate in a name other than that of the holder of the
Preferred Stock which is being converted.

                           M.       6M.     Closing of Books.  The Corporation 
will at no time close its transfer books against the transfer of any Preferred
Stock or of any shares of Common Stock issued or issuable upon the conversion of
any shares of Preferred Stock in any manner which interferes with the timely
conversion of such Preferred Stock, except as may otherwise be required to
comply with applicable securities laws.


   77




                           N.       6N.     Definition of Common Stock.  As used
in this paragraph 6, the term Common Stock" shall mean and include the
Corporation's authorized Common Stock, par value $.001 per share, as constituted
on the date of filing of these terms of the Preferred Stock, and shall also
include any capital stock of any class of the Corporation thereafter authorized
which shall not be limited to a fixed sum or percentage in respect of the rights
of the holders thereof to participate in dividends or in the distribution of
assets upon the voluntary or involuntary liquidation, dissolution or winding up
of the Corporation; provided that the shares of Common Stock receivable upon
conversion of shares of Preferred Stock shall include only shares designated as
Common Stock of the Corporation on the date of filing of this instrument, or in
case of any reorganization of reclassification of the outstanding shares
thereof, the stock, securities or assets provided for in subparagraph 6G.

                           O.       6O.     Mandatory Conversion.  If at any 
time (i) the Corporation shall effect a firm commitment underwritten public
offering of shares of Common Stock in which (A) the aggregate price paid for
such shares by the public shall be at least $15,000,000 and (B) the price paid
by the public for such shares shall be at least $4.32 per share (appropriately
adjusted to reflect the occurrence of any event described in subparagraph 6F),
or (ii) a Liquidity Event shall occur in which (a) the holders of shares of any
class of Preferred Stock would receive consideration for all of such shares (as
if converted to Common Stock) of at least $1.28 for (i) each share of Class A
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class A Convertible Preferred Stock is convertible; at least $3.04 for
(i) each share of Class B Convertible Preferred Stock is convertible; at least
$5.76 for (i) each share of Class C Convertible Preferred Stock or (ii) all
shares of Common Stock into which such share of Class C Convertible Preferred
Stock is convertible; or at least $6.03 per share for (i) each share of Class D
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class D Convertible Preferred Stock is convertible, then effective upon
the closing of the sale of such shares by the Corporation pursuant to such
public offering or immediately prior to the occurrence of such Liquidity Event,
as the case may be, all outstanding shares of Preferred Stock (in the case of a
public offering) or such class of Preferred Stock (in the case of a Liquidity
Event) shall automatically convert to shares of Common Stock on the basis set
forth in this paragraph 6. Holders of shares of Preferred Stock so converted may
deliver to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to such holders) during its usual business hours, the certificate or
certificates for the shares so converted. As promptly as practicable thereafter,
the Corporation shall issue and deliver to such holder a certificate or
certificates for the number of whole shares of Common Stock to which such holder
is entitled, together with any cash dividends and payment in lieu of fractional
shares to which such holder may be entitled pursuant to subparagraph 6C. Until
such time as a holder of shares of Preferred Stock shall surrender his or its
certificates therefor as provided above, such certificates shall be deemed to
represent the shares of Common Stock to which such holder shall be entitled upon
the surrender thereof.



   78



  VII.   Redemption. The shares of Class B Convertible Preferred Stock, the
         Class C Convertible Preferred Stock and the Class D Convertible
         Preferred Stock shall be redeemed as follows:

                           A.       7A.     Mandatory Redemption.  On September
11, 2002, and on each of the next two anniversaries thereafter (the "Redemption
Dates," and each a "Redemption Date"), the Corporation shall redeem any

according to the percentages listed below:

Date of Redemption         Percentage of Shares of Class B Convertible Preferred
                           Stock, Class C Conver tible Preferred Stock and
                           Class D Conver tible Preferr ed Stock then Outsta
                           nding to be Redeemed

September 11, 2002              33-1/3% of all the shares of Class B Convertible
                                Preferred Stock, Class C Convertible Preferred
                                Stock and Class D Convertible Preferred Stock
                                outstanding on September 11, 2002.

September 11, 2003              50% of all the shares of Class B Convertible 
                                Preferred Stock, Class C Convertible Preferred
                                Stock and Class D Convertible Preferred Stock
                                outstanding on September 11, 2003

September 11, 2004              100% of all the shares of Class B Convertible 
                                Preferred Stock, Class C Convertible Preferred
                                Stock and Class D Convertible Preferred Stock
                                outstanding on September 11, 2004

                           B.       7B.     Redemption Price and Payment.  The 
shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock to be redeemed on any Redemption
Date shall be redeemed by paying for each share in cash an amount equal to
$0.76, $1.44 and $3.57 per share (appropriately adjusted to reflect the
occurrence of any event described in subparagraphs 6F or 6G), respectively,
plus, in the case of each share, an amount equal to all dividends, excluding
Accruing Dividends, declared but upon thereon, computed to such Redemption Date,
such amount being referred to as the "Redemption Price." Such payment shall be
made in full on the applicable Redemption Date to the holders entitled thereto.

                           C.       7C.     Redemption Mechanics.  At least 20 
but not more than 30 days prior to each Redemption Date, written notice (the
"Redemption Notice") shall be given by the Corporation by delivery in person,
certified or registered mail, return receipt requested, telecopier or telex, to
each holder of record (at the close of business on the business day next
preceding the day on which the Redemption Notice is given) 



   79


of shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock notifying such holder of the
redemption and specifying the Redemption Price, such Redemption Date, the number
of shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and/or Class D Convertible Preferred Stock to be redeemed from such holder
(computed on a pro rata basis in accordance with the number of such shares held
by all holders thereof) and the place where said Redemption Price shall be
payable. The Redemption Notice shall be addressed to each holder at his address
as shown by the records of the Corporation. From and after the close of business
on a Redemption Date, unless there shall have been a default in the payment of
the Redemption Price, all rights of holder of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock (except the right to receive the Redemption Price) shall cease
with respect to the shares to be redeemed on such Redemption Date, and such
shares shall not thereafter be transferred on the books of the Corporation or be
deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock on a Redemption Date are insufficient to redeem the total number
of shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock to be redeemed on such Redemption
Date, the holders of such shares shall share ratably in any funds legally
available for redemption of such shares according to the respective amounts
which would be payable to them if the full number of shares to be redeemed on
such Redemption Date were actually redeemed. The shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock required to be redeemed but not so redeemed shall remain
outstanding and entitled to all rights and preferences provided herein. At any
time thereafter when additional funds of the Corporation are legally available
for the redemption of such shares of Class B Convertible Preferred Stock, Class
C Convertible Preferred Stock and Class D Convertible Preferred Stock, such
funds will be used, at the end of the next succeeding fiscal quarter, to redeem
the balance of such shares, or such portion thereof for which funds are then
legally available, on the basis set forth above.

                           D.       7D.     Redeemed or Otherwise Acquired 
Shares to be Retired. Any shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock and Class D Convertible Preferred Stock redeemed
pursuant to this paragraph 7 or otherwise acquired by the Corporation in any
manner whatsoever shall be canceled and shall not under any circumstances be
reissued; and the Corporation may from time to time take such appropriate
corporate action as may be necessary to reduce accordingly the number of
authorized shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock.

                           E.       7E.     Delay of Redemption.  
Notwithstanding paragraph 7A hereof, the Corporation shall not be required to
redeem any shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock on any Redemption Date
if the cost to the Corporation of such redemption would be greater than one-half
of the Corporation's available average 


   80



cash working capital balance for the quarter immediately preceding such
Redemption Date. If a redemption is delayed pursuant to this Paragraph 7E, the
Corporation shall redeem the shares to be so redeemed within 120 days of such
Redemption Date.

  VIII.  Amendments.  No provision of these terms of the Preferred Stock may be 
         amended, modified or waived without the written consent or affirmative
         vote of the holders of at least two-thirds of the then outstanding
         shares of Class D Convertible Preferred Stock and Class C Convertible
         Preferred Stock and at least a majority of the then outstanding shares
         of Class D Convertible Preferred Stock; provided, however, that so long
         as TTC Ventures holds at least two percent (2%) of the outstanding
         shares of Common Stock of the Corporation (assuming the conversion of
         all outstanding Preferred Stock), no amendment shall be made to the
         provisions of Section 2C relating to the representation of the holders
         of Class D Convertible Preferred Stock without the consent of TTC
         Ventures and that so long as ADP holds at least two percent (2%) of the
         outstanding shares of Common Stock of the Corporation (assuming
         the conversion of all outstanding Preferred Stock), no amendment shall
         be made to the provisions of the sixth sentence of Section 2C relating
         to the representation of the holders of Class D Convertible Preferred
         Stock without the consent of ADP.

                            TERMS OF PREFERRED STOCK







                           I.     Number of Shares. There shall be four classes 
of Preferred Stock. The Class A Convertible Preferred Stock shall consist of
1,562,500 shares, the Class B Convertible Preferred Stock shall consist of
2,151,420 shares, the Class C Convertible Preferred Stock shall consist of
3,188,889 shares and the Class D Convertible Preferred Stock shall consist of
2,045,785 shares. The Class A Convertible Preferred Stock, the Class B
Convertible Preferred Stock, the Class C Convertible Preferred Stock and the
Class D Convertible Preferred Stock shall sometimes be referred to herein
collectively as the "Preferred Stock."

                           II.    Voting.

                                    A.      2A.      General.  Except as may be
otherwise provided in these terms of the Preferred Stock or by law, the
Preferred Stock shall vote together with all other classes and class of stock of
the Corporation as a single class on all actions to be taken by the stockholders
of the Corporation, including, but not limited to actions amending the
Certificate of Incorporation of the Corporation to increase the number of
authorized shares of Common Stock. Each share of Preferred Stock shall entitle
the holder thereof to such number of votes per share on each such action as
shall equal the number of shares of Common Stock (including fractions of a
share) into which each share of Preferred Stock is then convertible.

                                    B.      2B.      Board Size.  The 
Corporation shall not, without the written consent or affirmative vote of the
holders of at least two-thirds of the then outstanding shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock and Class D
Convertible Preferred Stock consenting or voting (as the case may be) as a
single class, given in writing or by vote at a meeting, increase the maximum
number of directors constituting the Board of Directors to a number in excess of
seven.

                                    C.      2C.      Board Seats.  So long as 
the outstanding Class A Convertible Preferred Stock represents at least 10% of
the outstanding Common Stock of the Corporation (assuming the conversion of all
outstanding Preferred Stock), the holders of the Class A Convertible Preferred
Stock, acting as a separate class, shall be entitled to elect one director of
the Corporation. So long as the outstanding Class B Convertible Preferred Stock
represents at least 5% of the outstanding Common Stock of the Corporation
(assuming the conversion of all outstanding Preferred Stock), the holders of the
Class B Convertible Preferred Stock, acting as a separate class, shall be
entitled to elect one director of the Corporation (the "Class B Director"). So
long as the outstanding Class C Convertible Preferred Stock represents at least
5% of the outstanding Common Stock of the Corporation (assuming the conversion
of all outstanding Preferred Stock), the holders of the Class C Convertible
Preferred Stock, acting as a separate class, shall be entitled to elect one
director of the Corporation (the "Class C Director"). The holders 


   84



of the Common Stock, acting as a separate class, shall be entitled to elect two
directors of the Corporation. So long as Thomson U.S. Inc. ("TTC Ventures")
owns, beneficially or of record, at least two percent (2%) of the outstanding
Common Stock of the Corporation (assuming the conversion of all outstanding
Preferred Stock), the holders of the Class D Convertible Preferred Stock (as
adjusted in accordance with subparagraph 6F or 6G), acting as a separate class,
shall be entitled to appoint one director of the Corporation (the "Class D
Director") and such Class D Director shall be nominated and appointed by TTC
Ventures on behalf of the holders of Class D Convertible Preferred Stock. A
seventh director of the Corporation shall be such person, if any, who has
received a majority vote of the holders of each of the Class B Convertible
Preferred Stock, the Class C Convertible Preferred Stock and the Class D
Convertible Preferred Stock, each acting as a separate class, and a majority
vote of the holders of the Common Stock, acting as a separate class. At any
meeting (or in a written consent in lieu thereof) held for the purpose of
electing directors, the presence in person or by proxy (or the written consent)
of the holders of a majority of the shares of Class D Convertible Preferred
Stock then outstanding shall constitute a quorum of the Class D Convertible
Preferred Stock for the election of the director to be elected solely by the
holders of the Class D Convertible Preferred Stock, the presence in person or by
proxy (or the written consent) of the holders of a majority of the shares of
Class C Convertible Preferred Stock then outstanding shall constitute a quorum
of the Class C Convertible Preferred Stock for the election of the director to
be elected solely by the holders of the Class C Convertible Preferred Stock, the
presence in person or by proxy (or the written consent) of the holders of a
majority of the shares of Class B Convertible Preferred Stock then outstanding

election of the director to be elected solely by the holders of the Class B
Convertible Preferred Stock, and the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Class A
Convertible Preferred Stock then outstanding shall constitute a quorum of the
Class A Convertible Preferred Stock for the election of the director to be
elected solely by the holders of the Class A Convertible Preferred Stock. A
vacancy in any directorship elected by the holders of the Class A Convertible
Preferred Stock, Class B Convertible Preferred Stock or Class C Convertible

of the Class A Convertible Preferred Stock, Class B Convertible Preferred Stock
or Class C Convertible Preferred Stock respectively; a vacancy in the

Stock.

                           III.     Dividends.  The holders of the Class A 
Convertible Preferred Stock shall be entitled to receive, out of funds legally
available therefor, (i) when and if declared by at least four members of the
Board of Directors, or (ii) upon any liquidation, dissolution or winding up of
the Corporation, quarterly dividends at the rate per annum of $0.0224 per share
(the "Class A Accruing Dividends"). The holders of the Class B Convertible
Preferred Stock shall be entitled to receive, out of funds legally available

quarterly dividends at the rate per annum of $0.0532 per share (the "Class B

dividend shall be paid on the Preferred Stock, other than Accruing Dividends, or
on the Common Stock.

                           IV.      Liquidation.

                                    A.      4A.      Upon any liquidation, 
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of the shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock and Class D Convertible Preferred Stock shall first
be entitled, before any distribution or payment is made upon any stock ranking
on liquidation junior to the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock, to be
paid an amount equal to $0.76, $1.44 and $3.57 per share, respectively, plus, in
the case of each share of Class B Convertible Preferred Stock, an amount equal
to all Class B Accruing Dividends unpaid thereon (whether or not declared) and
any other dividends declared but unpaid thereon, in the case of each share of
Class C Convertible Preferred Stock, an amount equal to all Class C Accruing
Dividends unpaid thereon (whether or not declared) and in the case of each share
of Class D Convertible Preferred Stock, an amount equal to all Class D Accruing
Dividends paid thereon (whether or not declared), and any other dividends
declared but unpaid thereon, computed to the date payment thereof is made
available, such amount payable with respect to one share of Class B Convertible
Preferred Stock being sometimes referred to as the "Class B Liquidation
Preference Payment," such amount payable with respect to one share of Class C
Convertible Preferred Stock being sometimes referred to as the "Class C
Liquidation Preference Payment," such amount payable with respect to one share
of Class D Convertible Preferred Stock being sometimes referred to as the "Class
D Liquidation Preference Payment", and with respect to all shares of Class B
Convertible Preferred Stock, Class C Convertible Preferred Stock and Class D
Convertible Preferred Stock being sometimes referred to as the "Classes B, C and
D Liquidation Preference Payments." If upon such liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the assets to
be distributed among the holders of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock and Class D Convertible Preferred Stock shall be
insufficient to permit payment in full to the holders 



   86


of Class B Convertible Preferred Stock, Class C Convertible Preferred Stock and
Class D Convertible Preferred Stock of the Classes B, C and D Liquidation
Preference Payments, then the entire assets of the Corporation to be so
distributed shall be distributed ratably, on an as-converted basis, among the
holders of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock.

                                    B.      4B.      Upon any liquidation, 
dissolution or winding up of the Corporation, whether voluntary or involuntary,
after the holders of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock shall have been paid in
full the amounts to which they shall be entitled pursuant to paragraph 4A, the
holders of the shares of Class A Convertible Preferred Stock shall then be
entitled, before any distribution or payment is made upon any stock ranking on
liquidation junior to the Class A Convertible Preferred Stock, to be paid an
amount equal to $.32 per share plus, in the case of each share, an amount equal
to all Class A Accruing Dividends unpaid thereon (whether or not declared)
computed to the date payment thereof is made available, such amount payable with
respect to one share of Class A Convertible Preferred Stock being sometimes
referred to as the "Class A Liquidation Preference Payment" and with respect to
all shares of Class A Convertible Preferred Stock being sometimes referred to as
the "Class A Liquidation Preference Payments." The Class A Liquidation
Preference Payments and the Classes B, C and D Liquidation Preference Payments
are sometimes referred to herein collectively as the "Liquidation Preference
Payments." If upon such liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the assets to be distributed
among the holders of Class A Convertible Preferred Stock shall be insufficient
to permit payment in full to the holders of Class A Convertible Preferred Stock
of the Class A Liquidation Preference Payments, then the entire remaining assets
of the Corporation to be so distributed shall be distributed ratably among the
holders of Class A Convertible Preferred Stock.

                                    C.      4C.      Upon any such liquidation, 
dissolution or winding up of the Corporation, immediately after the holders of
Class B Convertible Preferred Stock, Class C Convertible Preferred Stock, Class
D Convertible Preferred Stock and Class A Convertible Preferred Stock shall have
been paid in full their respective Liquidation Preference Payments, the
remaining net assets of the Corporation available for distribution shall be
distributed ratably among the holders of Preferred Stock and Common Stock (with
each share of Preferred Stock being deemed, for such purpose, to be equal to the
number of shares of Common Stock (including fractions of a share) into which
such share of Preferred Stock is convertible immediately prior to the close of
business on the business day fixed for such distribution). Unless otherwise
agreed by holders of at least two-thirds of the Class B Convertible Preferred
Stock and the Class C Convertible Preferred Stock, each acting as a separate
class, and a majority of the Class D Convertible Preferred Stock, acting as a
separate class, the consolidation or merger of the Corporation into or with any
other entity or entities which results in the exchange of outstanding shares of
the Corporation for securities or other consideration issued or paid or caused
to be issued or paid by any such entity or affiliate thereof (other than a
merger to reincorporate the Corporation in a different jurisdiction), and the
sale, lease,



   87



abandonment, transfer or other disposition by the Corporation of all or
substantially all its assets (each such event a "Liquidity Event"), shall be
deemed to be a liquidation, dissolution or winding up of the Corporation within
the meaning of the provisions of this paragraph 4.

                                    D.      4D.      Written notice of such 
liquidation, dissolution or winding up, stating a payment date, the amount of
the Liquidation Preference Payments and the place where said Liquidation
Preference Payments shall be payable, shall be delivered in person, mailed by
certified or registered mail, return receipt requested, or sent by telecopier or
telex, not less than 20 days prior to the payment date stated therein, to the
holders of record of Preferred Stock, such notice to be addressed to each such
holder at its address as shown by the records of the Corporation. For purposes
hereof, the Common Stock shall rank on liquidation junior to the Class A
Convertible Preferred Stock, the Class B Convertible Preferred Stock, the Class
C Convertible Preferred Stock and the Class D Convertible Preferred Stock.

                           V.       Restrictions.  At any time when shares of 
Class B Convertible Preferred Stock, Class C Convertible Preferred Stock and
Class D Convertible Preferred Stock are outstanding, except where the vote or
written consent of the holders of a greater number of shares of the Corporation
is required by law or by the Certificate of Incorporation, and in addition to
any other vote required by law or the Certificate of Incorporation, without the
approval of the holders of at least a majority of the then outstanding shares of
the Class B Convertible Preferred Stock, Class C Convertible Preferred Stock and
the Class D Convertible Preferred Stock, consenting or voting (as the case may
be) as separate classes, given in writing or by vote at a meeting, the
Corporation will not:

                                    A.      5A.      Create or authorize the 
creation of any additional class or series of shares of stock unless the same
ranks junior to the Class B Convertible Preferred Stock, the Class C Convertible
Preferred Stock and the Class D Convertible Preferred Stock as to the
distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, or increase the authorized
amount of the Class B Convertible Preferred Stock, the Class C Convertible
Preferred Stock or the Class D Convertible Preferred Stock or increase the
authorized amount of any additional class or series of shares of stock unless
the same ranks junior to the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, or create or authorize any
obligation or security convertible into shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock or Class D Convertible Preferred
Stock or into shares of any other class or series of stock unless the same ranks
junior to the Class B Convertible Preferred Stock, the Class C Convertible
Preferred Stock and the Class D Convertible Preferred Stock as to the
distribution of assets on the liquidation, dissolution or winding up of the
Corporation, redemption and the payment of dividends, whether any such creation,
authorization or increase shall be



   88


by means of amendment to the Certificate of Incorporation or by merger,
consolidation or otherwise; provided, that such consent shall not be
unreasonably withheld for the creation or issuance of an additional class or
series of shares ranking senior to the Class B Convertible Preferred Stock, the
Class C Convertible Preferred Stock and the Class D Convertible Preferred Stock
as to the distribution of assets on the liquidation, dissolution or winding up
of the Corporation, redemption and the payment of dividends (a "Senior
Security"), but provided further, that if, within a reasonable time of the
submission of a proposal for the issuance of a Senior Security, information
comes to light indicating that such consent was withheld solely or primarily for
the purpose of negotiating the price of an additional investment by the holders
of the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock and/or the Class D Convertible Preferred Stock, then such consent shall be
deemed to have been unreasonably withheld for purposes of this subparagraph 5A.

                                    B.      5B.      Consent to any liquidation,
dissolution or winding up of the Corporation or consolidate or merge into or
with any other entity or entities or sell, lease, abandon, transfer or otherwise
dispose of all or substantially all its assets, unless such action would result
in an annualized return to the holders of the Class B Convertible Preferred
Stock, the Class C Convertible Preferred Stock and the Class D Convertible
Preferred Stock of at least 30%;

                                    C.      5C.      Amend, alter or repeal its
Certificate of Incorporation or By-Laws if the effect would be materially
detrimental or adverse in any manner with respect to the rights of the holders
of the Class B Convertible Preferred Stock, the Class C Convertible Preferred
Stock and/or the Class D Convertible Preferred Stock;

                                    D.      5D.      Purchase or set aside any 
sums for the purchase of, or pay any dividend or make any distribution on, any
shares of stock other than the Class B Convertible Preferred Stock, the Class C
Convertible Preferred Stock and the Class D Convertible Preferred Stock, except
for (i) Class A Accruing Dividends, (ii) dividends or other distributions
payable on the Common Stock solely in the form of additional shares of Common
Stock, and (iii) the purchase of shares of Common Stock from former employees of
the Corporation who acquired such shares directly from the Corporation, if each
such purchase is made pursuant to contractual rights held by the Corporation
relating to the termination of employment of such former employee and the
purchase price (except in the case of agreements executed prior to July 12,
1996) does not exceed the original issue price paid by such former employee to
the Corporation for such shares; or

                                    E.      5E.      Redeem or otherwise acquire
any shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock except as expressly authorized in
paragraph 7 hereof or pursuant to a purchase offer made pro rata to all holders
of the shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D 


   89



Convertible Preferred Stock on the basis of the aggregate number of outstanding
shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and/or Class D Convertible Preferred Stock then held by each such holder.

         Prior to the completion of the sale of up to 2,045,785 shares of Class
D Convertible Preferred Stock as set forth in the Class D Convertible Preferred
Stock Purchase Agreement, dated as of September 11, 1997, if a vote concerning
any of the matters set forth in this Section 5 results in a tie and the results
of such vote would equally affect each of the Class B Convertible Preferred
Stock, the Class C Convertible Preferred Stock and the Class D Convertible
Preferred Stock, the tie- breaking vote shall be cast by the Chief Executive
Officer of the Company. Upon the completion of such sale of the Class D
Convertible Preferred Stock, the provisions of this paragraph shall no longer
remain in effect.

                           VI.      Conversions.  The holders of shares of 
Preferred Stock shall have the following conversion rights:

                                    A.      6A.      Right to Convert.  Subject 
to the terms and conditions of this paragraph 6, the holder of any share or
shares of Preferred Stock shall have the right, at its option at any time, to
convert any such shares of Preferred Stock into such number of fully paid and
nonassessable shares of Common Stock as is obtained by (i) multiplying the
number of shares of Preferred Stock so to be converted by the Original Purchase
Price of such share (which shall be $0.32 in the case of the Class A Convertible
Preferred Stock, $.76 in the case of Class B Convertible Preferred Stock, $1.44
in the case of Class C Convertible Preferred Stock and $3.57 in the case of
Class D Convertible Preferred Stock) and (ii) dividing the result by the
conversion price of the Original Purchase Price of such share or, in case an
adjustment of such price has taken place pursuant to the further provisions of
this paragraph 6, then by the conversion price as last adjusted and in effect at
the date any share or shares of Preferred Stock are surrendered for conversion
(such price, or such price as last adjusted, being referred to as the
"Conversion Price," with respect to the Class B Convertible Preferred Stock, the
"Class B Conversion Price," with respect to the Class C Convertible Preferred
Stock, the "Class C Conversion Price" and, with respect to the Class D
Convertible Preferred Stock, the "Class D Conversion Price"). Such rights of
conversion shall be exercised by the holder thereof by giving written notice
that the holder elects to convert a stated number of shares of Preferred Stock
into Common Stock and by surrender of a certificate or certificates for the
shares so to be converted to the Corporation at its principal office (or such
other office or agency of the Corporation as the Corporation may designate by
notice in writing to the holders of the Preferred Stock) at any time during its
usual business hours on the date set forth in such notice, together with
a statement of the name or names (with address) in which the certificate or
certificates for shares of Common Stock shall be issued.

                                    B.      6B.      Issuance of Certificates;
Time Conversion Effected. Promptly after the receipt of the written notice
referred to in subparagraph 6A 


   90



and surrender of the certificate or certificates for the share or shares of
Preferred Stock to be converted, the Corporation shall issue and deliver, or
cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, a certificate or certificates for the number of
whole shares of Common Stock issuable upon the conversion of such share or
shares of Preferred Stock. To the extent permitted by law, such conversion shall
be deemed to have been effected and the Conversion Price shall be determined as
of the close of business on the date on which such written notice shall have
been received by the Corporation and the certificate or certificates for such
share or shares shall have been surrendered as aforesaid, and at such time the
rights of the holder of such share or shares of Preferred Stock shall cease, and
the person or persons in whose name or names any certificate or certificates for
shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become the holder or holders of record of the shares represented thereby.

                                    C.      6C.      Fractional Shares; 
Dividends; Partial Conversion. No fractional shares shall be issued upon
conversion of Preferred Stock into Common Stock and no payment or adjustment
shall be made upon any conversion on account of any cash dividends on the Common
Stock issued upon such conversion. At the time of each conversion, the
Corporation shall pay in cash an amount equal to all dividends, excluding
Accruing Dividends, accrued and unpaid on the shares of Preferred Stock
surrendered for conversion to the date upon which such conversion is deemed to
take place as provided in subparagraph 6B. In case the number of shares of
Preferred Stock represented by the certificate or certificates surrendered
pursuant to subparagraph 6A exceeds the number of shares converted, the
Corporation shall, upon such conversion, execute and deliver to the holder, at
the expense of the Corporation, a new certificate or certificates for the number
of shares of Preferred Stock represented by the certificate or certificates
surrendered which are not to be converted. If any fractional share of Common
Stock would, except for the provisions of the first sentence of this
subparagraph 6C, be delivered upon such conversion, the Corporation, in lieu of
delivering such fractional share, shall pay to the holder surrendering the
Preferred Stock for conversion an amount in cash equal to the current market
price of such fractional share as determined in good faith by the Board of
Directors of the Corporation.

                                    D.      6D.      Adjustment of Price Upon
Issuance of Common Stock. Except as provided in subparagraph 6E, if and whenever
the Corporation shall issue or sell, or is, in accordance with subparagraphs
6D(1) through 6D(7), deemed to have issued or sold, any shares of Common Stock
for a consideration per share less than (i) the Class B Conversion Price in
effect immediately prior to the time of such issue or sale, (ii) the Class C
Conversion Price in effect immediately prior to the time of such issue or sale,
or (iii) the Class D Conversion Price in effect immediately prior to the time of
such issue or sale, then, forthwith upon such issue or sale, the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price, as the case may be, shall be reduced to the price determined by dividing
(i) an amount equal to the sum of (a) the number of shares of Common Stock
outstanding immediately prior to such issue or sale multiplied by the then
existing Class B Conversion Price, the then existing Class C Conversion Price or
the then existing Class D Conversion Price, as the 



   91


case may be, and (b) the consideration, if any, received by the Corporation upon
such issue or sale, by (ii) the total number of shares of Common Stock
outstanding immediately after such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                                            1.       6D(1)    Issuance of Rights
or Options. In case at any time the Corporation shall in any manner grant
(whether directly or by assumption in a merger or otherwise) any warrants or
other rights to subscribe for or to purchase, or any options for the purchase
of, Common Stock or any stock or security convertible into or exchangeable for
Common Stock (such warrants, rights or options being called "Options" and such
convertible or exchangeable stock or securities being called "Convertible
Securities") whether or not such Options or the right to convert or exchange any
such Convertible Securities are immediately exercisable, and the price per share
for which Common Stock is issuable upon the exercise of such Options or upon the
conversion or exchange of such Convertible Securities (determined by dividing
(i) the total amount, if any, received or receivable by the Corporation as
consideration for the granting of such Options, plus the minimum aggregate
amount of additional consideration payable to the Corporation upon the exercise
of all such Options, plus, in the case of such Options which relate to
Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof, by (ii) the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon the conversion or exchange of all such Convertible Securities
issuable upon the exercise of such Options) shall be less than the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price in effect immediately prior to the time of the granting of such Options,
then the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon conversion or exchange of the total maximum
amount of such Convertible Securities issuable upon the exercise of such Options
shall be deemed to have been issued for such price per share as of the date of
granting of such Options or the issuance of such Convertible Securities and
thereafter shall be deemed to be outstanding. Except as otherwise provided in
subparagraph 6D(3), no adjustment of the Class B Conversion Price, the Class C
Conversion Price and/or the Class D Conversion Price shall be made upon the
actual issue of such Common Stock or of such Convertible Securities upon
exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

                                            2.       6D(2)    Issuance of 
Convertible Securities. In case the Corporation shall in any manner issue
(whether directly or by assumption in a merger or otherwise) or sell any
Convertible Securities, whether or not the rights to exchange or convert any
such Convertible Securities are immediately exercisable, and the price per share
for which Common Stock is issuable upon such conversion or exchange (determined
by dividing (i) the total amount received or receivable by the 



   92



Corporation as consideration for the issue or sale of such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (ii)
the total maximum number of shares of Common Stock issuable upon the conversion
or exchange of all such Convertible Securities) shall be less than the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price in effect immediately prior to the time of such issue or sale, then the
total maximum number of shares of Common Stock issuable upon conversion or
exchange of all such Convertible Securities shall be deemed to have been issued
for such price per share as of the date of the issue or sale of such Convertible
Securities and thereafter shall be deemed to be outstanding, provided that (a)
except as otherwise provided in subparagraph 6D(3), no adjustment of the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price shall be made upon the actual issue of such Common Stock upon conversion
or exchange of such Convertible Securities and (b) if any such issue or sale of
such Convertible Securities is made upon exercise of any Options to purchase any
such Convertible Securities for which adjustments of the Class B Conversion
Price and/or the Class C Conversion Price and/or the Class D Conversion Price
have been or are to be made pursuant to other provisions of this subparagraph
6D, no further adjustment of the Class B Conversion Price, the Class C
Conversion Price and/or the Class D Conversion Price shall be made by reason of
such issue or sale.

                                            3.       6D(3)    Change in Option 
Price or Conversion Rate. Upon the happening of any of the following events,
namely, if the purchase price provided for in any Option referred to in
subparagraph 6D(1), the additional consideration, if any, payable upon the
conversion or exchange of any Convertible Securities referred to in subparagraph
6D(1) or 6D(2), or the rate at which Convertible Securities referred to in
subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common
Stock shall change at any time (including, but not limited to, changes under or
by reason of provisions designed to protect against dilution), the Class B
Conversion Price, the Class C Conversion Price and/or the Class D Conversion
Price in effect at the time of such event shall forthwith be readjusted to the
Class B Conversion Price, Class C Conversion Price or the Class D Conversion
Price, as the case may be, which would have been in effect at such time had such
Options or Convertible Securities still outstanding provided for such changed
purchase price, additional consideration or conversion rate, as the case may be,
at the time initially granted, issued or sold, but only if as a result of such
adjustment the Class B Conversion Price, the Class C Conversion Price and/or the
Class D Conversion Price then in effect hereunder is thereby reduced; and on the
termination or expiration of any such Option or any such right to convert or
exchange such Convertible Securities, the Class B Conversion Price, the Class C
Conversion Price and/or the Class D Conversion Price then in effect hereunder
shall forthwith be increased to the Class B Conversion Price, Class C Conversion
Price or Class D Conversion Price, as the case may be, which would have
been in effect at the time of such termination or expiration had such Option or
Convertible Securities, to the extent outstanding immediately prior to such
termination or expiration, never been issued.



   93





                                            4.       6D(4)    Stock Dividends. 
In case the Corporation shall declare a dividend or make any other distribution
upon any stock of the Corporation (other than the Common Stock) payable in
Common Stock, Options or Convertible Securities, then any Common Stock, Options
or Convertible Securities, as the case may be, issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold without
consideration.

                                            5.       6D(5)    Consideration for
Stock. In case any shares of Common Stock, Options or Convertible Securities
shall be issued or sold for cash, the consideration received therefor shall be
deemed to be the amount received by the Corporation therefor, without deduction
therefrom of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case
any shares of Common Stock, Options or Convertible Securities shall be issued or
sold for a consideration other than cash, the amount of the consideration other
than cash received by the Corporation shall be deemed to be the fair value of
such consideration as determined in good faith by the Board of Directors of the
Corporation, without deduction of any expenses incurred or any underwriting
commissions or concessions paid or allowed by the Corporation in connection
therewith. In case any Options shall be issued in connection with the issue and
sale of other securities of the Corporation, together comprising one integral
transaction in which no specific consideration is allocated to such Options by
the parties thereto, such Options shall be deemed to have been issued for such
consideration as determined in good faith by the Board of Directors of the
Corporation.

                                            6.       6D(6)    Record Date.  In 
case the Corporation shall take a record of the holders of its Common Stock for
the purpose of entitling them (i) to receive a dividend or other distribution
payable in Common Stock, Options or Convertible Securities or (ii) to subscribe
for or purchase Common Stock, Options or Convertible Securities, then such
record date shall be deemed to be the date of the issue or sale of the shares of
Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of
such right of subscription or purchase, as the case may be.

                                            7.       6D(7)    Treasury Shares. 
The number of shares of Common Stock outstanding at any given time shall not
include shares owned or held by or for the account of the Corporation, and the
disposition of any such shares shall be considered an issue or sale of Common
Stock for the purpose of this subparagraph 6D.

                                    E.      6E.      Certain Issues of Common 
Stock Excepted. Anything herein to the contrary notwithstanding, the Corporation
shall not be required to make any adjustment of the Class B Conversion Price,
the Class C Conversion Price or the Class D Conversion Price in the case of the
issuance from and after the date of filing of these terms of the Preferred Stock
of up to an aggregate of 1,950,000 shares (appropriately adjusted to reflect the
occurrence of any event described in subparagraphs 6F or 6G) (the "Reserved
Shares") of Common Stock to directors, officers, 



   94



employees or consultants of the Corporation in connection with their service as
directors of the Corporation, their employment by the Corporation or their
retention as consultants by the Corporation (provided that the number of
Reserved Shares may be increased (a) prior to December 31, 1998, with the
approval of a majority of the Board of Directors including the Class B Director,
the Class C Director and the Class D Director and (b) after December 31, 1998,
with the approval of either (i) a majority of the Board of Directors including
the Class B Director, the Class C Director and the Class D Director or (ii) all
directors other than the Class B Director, the Class C Director and the Class D
Director), plus such number of shares of Common Stock which are repurchased by
the Corporation from such persons after such date pursuant to contractual rights
held by the Corporation and at repurchase prices not exceeding the respective
original purchase prices paid by such persons to the Corporation therefor.

                                    F.      6F.      Subdivision or Combination
of Common Stock. In case the Corporation shall at any time subdivide (by any
stock split, stock dividend or otherwise) its outstanding shares of Common Stock
into a greater number of shares, the Conversion Price in effect immediately
prior to such subdivision shall be proportionately reduced, and, conversely, in
case the outstanding shares of Common Stock shall be combined into a smaller
number of shares, the Conversion Price in effect immediately prior to such
combination shall be proportionately increased. In the case of any such
subdivision, no further adjustment shall be made pursuant to subparagraph 6D by
reason thereof.

                                    G.      6G.      Reorganization or 
Reclassification. If any capital reorganization or reclassification of the
capital stock of the Corporation shall be effected in such a way that holders of
Common Stock shall be entitled to receive stock, securities or assets with
respect to or in exchange for Common Stock, then, as a condition of such
reorganization or reclassification, lawful and adequate provisions shall be made
whereby each holder of a share or shares of Preferred Stock shall thereupon have
the right to receive, upon the basis and upon the terms and conditions specified
herein and in lieu of the shares of Common Stock immediately theretofore
receivable upon the conversion of such share or shares of Preferred Stock, such
shares of stock, securities or assets as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such Common Stock immediately theretofore receivable
upon such conversion had such reorganization or reclassification not taken
place, and in any such case appropriate provisions shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including without limitation provisions for adjustments of the Conversion
Price) shall thereafter be applicable, as nearly as may be, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
of such conversion rights.

                                    H.      6H.      Notice of Adjustment.  Upon
any adjustment of the Conversion Price, then and in each such case the
Corporation shall give written notice thereof, by delivery in person, certified
or registered mail, return receipt 


   95



requested, telecopier or telex, addressed to each holder of shares of Preferred
Stock at the address of such holder as shown on the books of the Corporation,
which notice shall state the Conversion Price resulting from such adjustment,
setting forth in reasonable detail the method upon which such calculation is
based.

                                    I.      6I.      Other Notices.  In case at
any time:

                                                     (1)      the Corporation
shall declare any dividend upon its Common Stock payable in cash or stock or
make any other distribution to the holders of its Common Stock;

                                                     (2)      the Corporation 
shall offer for subscription pro rata to the holders of its Common Stock any
additional shares of stock of any class or other rights;

                                                     (3)      there shall be any
capital reorganization or reclassification of the capital stock of the
Corporation, or a consolidation or merger of the Corpo ration with or into
another entity or entities, or a sale, lease, abandonment, transfer or other
dispo sition of all or substantially all its assets; or

                                                     (4)      there shall be a 
voluntary or involuntary dissolution, liquidation or winding up of the
Corporation; then, in any one or more of said cases, the Corporation shall give,
by delivery in person, certified or registered mail, return receipt requested,
telecopier or telex, addressed to each holder of any shares of Preferred Stock
at the address of such holder as shown on the books of the Corporation, (a) at
least 20 days' prior written notice of the date on which the books of the
Corporation shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of any such reorganization, reclassification, consolidation, merger,
disposition, dissolution, liquidation or winding up and (b) in the case of any
such reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding up, at least 20 days' prior written notice
of the date when the same shall take place. Such notice in accordance with the
foregoing clause (a) shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto and such notice in accordance with the foregoing
clause (b) shall also specify the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, disposition, dissolution, liquidation or winding up, as the case may be.

                                    J.      6J.      Stock to be Reserved.  The
Corporation will at all times reserve and keep available out of its authorized
Common Stock, solely for the purpose of issuance upon the conversion of
Preferred Stock as herein provided, such number of shares of Common Stock as
shall then be issuable upon the conversion of all outstanding shares of
Preferred Stock. The Corporation covenants that all shares of 


   96



Common Stock which shall be so issued shall be duly and validly issued and fully
paid and nonassessable and free from all taxes, liens and charges with respect
to the issue thereof, and, without limiting the generality of the foregoing, the
Corporation covenants that it will from time to time take all such action as may
be requisite to assure that the par value per share of the Common Stock is at
all times equal to or less than the Conversion Price in effect at the time. The
Corporation will take all such action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable
law or regulation, or of any requirement of any national securities exchange
upon which the Common Stock may be listed. The Corporation will not take any
action which results in any adjustment of the Conversion Price if the total
number of shares of Common Stock issued and issuable after such action upon
conversion of the Preferred Stock would exceed the total number of shares of
Common Stock then authorized by the Certificate of Incorporation.

                                    K.      6K.      No Reissuance of Preferred
Stock. Shares of Preferred Stock which are converted into shares of Common Stock
as provided herein shall not be reissued.

                                    L.      6L.      Issue Tax.  The issuance of
certificates for shares of Common Stock upon conversion of Preferred Stock shall
be made without charge to the holders thereof for any issuance tax in respect
thereof, provided that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance and
delivery of any certificate in a name other than that of the holder of the
Preferred Stock which is being converted.

                                    M.      6M.      Closing of Books.  The
Corporation will at no time close its transfer books against the transfer of any
Preferred Stock or of any shares of Common Stock issued or issuable upon the
conversion of any shares of Preferred Stock in any manner which
interferes with the timely conversion of such Preferred Stock, except as may
otherwise be required to comply with applicable securities laws.

                                    N.      6N.      Definition of Common Stock.
As used in this paragraph 6, the term "Common Stock" shall mean and include the
Corporation's authorized Common Stock, par value $.001 per share, as constituted
on the date of filing of these terms of the Preferred Stock, and shall also
include any capital stock of any class of the Corporation thereafter authorized
which shall not be limited to a fixed sum or percentage in respect of the rights
of the holders thereof to participate in dividends or in the distribution of
assets upon the voluntary or involuntary liquidation, dissolution or winding up
of the Corporation; provided that the shares of Common Stock receivable upon
conversion of shares of Preferred Stock shall include only shares designated as
Common Stock of the Corporation on the date of filing of this instrument, or in
case of any reorganization or reclassification of the outstanding shares
thereof, the stock, securities or assets provided for in subparagraph 6G.





   97


                                    O.      6O.      Mandatory Conversion.  If 
at any time (i) the Corpo ration shall effect a firm commitment underwritten
public offering of shares of Common Stock in which (A) the aggregate price paid
for such shares by the public shall be at least $15,000,000 and (B) the price
paid by the public for such shares shall be at least $4.32 per share
(appropriately adjusted to reflect the occurrence of any event described in
subparagraph 6F), or (ii) a Liquidity Event shall occur in which (a) the holders
of shares of any class of Preferred Stock would receive consideration for all of
such shares (as if converted to Common Stock) of at least $1.28 for (i) each
share of Class A Convertible Preferred Stock or (ii) all shares of Common Stock
into which such share of Class A Convertible Preferred Stock is convertible; at
least $3.04 for (i) each share of Class B Convertible Preferred Stock or (ii)
all shares of Common Stock into which such share of Class B Convertible
Preferred Stock is convertible; at least $5.76 for (i) each share of Class C
Convertible Preferred Stock or (ii) all shares of Common Stock into which such
share of Class C Convertible Preferred Stock is convertible; or at least $6.03
per share for (i) each share of Class D Convertible Preferred Stock or (ii) all
shares of Common Stock into which such share of Class D Convertible Preferred
Stock is convertible, then effective upon the closing of the sale of such shares
by the Corporation pursuant to such public offering or immediately prior to the
occurrence of such Liquidity Event, as the case may be, all outstanding shares
of Preferred Stock (in the case of a public offering) or such class of Preferred
Stock (in the case of a Liquidity Event) shall automatically convert to shares
of Common Stock on the basis set forth in this paragraph 6. Holders of shares of
Preferred Stock so converted may deliver to the Corporation at its principal
office (or such other office or agency of the Corporation as the Corporation may
designate by notice in writing to such holders) during its usual business hours,
the certificate or certificates for the shares so converted. As promptly as
practicable thereafter, the Corporation shall issue and deliver to such holder a
certificate or certificates for the number of whole shares of Common Stock to
which such holder is entitled, together with any cash dividends and payment in
lieu of fractional shares to which such holder may be entitled pursuant to
subparagraph 6C. Until such time as a holder of shares of Preferred Stock shall
surrender his or its certificates therefor as provided above, such certificates
shall be deemed to represent the shares of Common Stock to which such holder
shall be entitled upon the surrender thereof.

                           VII.     Redemption.  The shares of Class B 
Convertible Preferred Stock, the Class C Convertible Preferred Stock and the
Class D Convertible Preferred Stock shall be redeemed as follows:

                                    A.      7A.      Mandatory Redemption.  On 
September 11, 2002, and on each of the next two anniversaries thereafter (the
"Redemption Dates," and each a "Redemption Date"), the Corporation shall redeem

Convertible Preferred Stock and the Class D Convertible Preferred Stock
according to the percentages listed below:


  Date of Redemption                Percentage of Shares of Class B Convertible

   98



                                    Stock, Class C Convertible Preferred Stock
                                    and Class D Convertible Preferred Stock then
                                    Outstanding to be Redeemed

  September 11, 2002                       33-1/3% of all the shares of Class B 
                                           Convert ible Preferred Stock, Class C
                                           Convertible Preferred Stock and Class
                                           D Convertible Preferred Stock
                                           outstanding on September 11, 2002

  September 11, 2003                       50% of all the shares of Class B
                                           Convertible Preferred Stock, Class C
                                           Convertible Preferred Stock and Class
                                           D Convertible Preferred Stock
                                           outstanding on September 11, 2003

  September 11, 2004                       100% of all the shares of Class B
                                           Convertible Preferred Stock, Class C
                                           Convertible Preferred Stock and Class
                                           D Convertible Preferred Stock
                                           outstanding on September 11, 2004

                                    B.      7B.      Redemption Price and 
Payment. The shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock to be redeemed on any
Redemption Date shall be redeemed by paying for each share in cash an amount
equal to $0.76, $1.44 and $3.57 per share (appropriately adjusted to reflect the
occurrence of any event described in subparagraphs 6F or 6G), respectively,
plus, in the case of each share, an amount equal to all dividends, excluding
Accruing Dividends, declared but unpaid thereon, computed to such Redemption
Date, such amount being referred to as the "Redemption Price". Such payment
shall be made in full on the applicable Redemption Date to the holders entitled
thereto.

                                    C.      7C.      Redemption Mechanics.  At
least 20 but not more than 30 days prior to each Redemption Date, written notice
(the "Redemption Notice") shall be given by the Corporation by delivery in
person, certified or registered mail, return receipt requested, telecopier or
telex, to each holder of record (at the close of business on the business day
next preceding the day on which the Redemption Notice is given) of shares of
Class B Convertible Preferred Stock, Class C Convertible Preferred Stock and
Class D Convertible Preferred Stock notifying such holder of the redemption and
specifying the Redemption Price, such Redemption Date, the number of shares of





   99



Class B Convertible Preferred Stock, Class C Convertible Preferred Stock and/or
Class D Convertible Preferred Stock to be redeemed from such holder (computed on
a pro rata basis in accordance with the number of such shares held by all
holders thereof) and the place where said Redemption Price shall be payable. The
Redemption Notice shall be addressed to each holder at his address as shown by
the records of the Corporation. From and after the close of business on a
Redemption Date, unless there shall have been a default in the payment of the
Redemption Price, all rights of holders of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock (except the right to receive the Redemption Price) shall cease
with respect to the shares to be redeemed on such Redemption Date, and such
shares shall not thereafter be transferred on the books of the Corporation or be
deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock on a Redemption Date are insufficient to redeem the total number
of shares of Class B Convertible Preferred Stock, Class C Convertible Preferred
Stock and Class D Convertible Preferred Stock to be redeemed on such Redemption
Date, the holders of such shares shall share ratably in any funds legally
available for redemption of such shares according to the respective amounts
which would be payable to them if the full number of shares to be redeemed on
such Redemption Date were actually redeemed. The shares of Class B Convertible
Preferred Stock, Class C Convertible Preferred Stock and Class D Convertible
Preferred Stock required to be redeemed but not so redeemed shall remain
outstanding and entitled to all rights and preferences provided herein. At any
time thereafter when additional funds of the Corporation are legally available
for the redemption of such shares of Class B Convertible Preferred Stock, Class
C Convertible Preferred Stock and Class D Convertible Preferred Stock, such
funds will be used, at the end of the next succeeding fiscal quarter, to redeem
the balance of such shares, or such portion thereof for which funds are then
legally available, on the basis set forth above.

                                    D.      7D.      Redeemed or Otherwise 
Acquired Shares to be Retired. Any shares of Class B Convertible Preferred
Stock, Class C Convertible Preferred Stock and Class D Convertible Preferred
Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the
Corporation in any manner whatsoever shall be canceled and shall not under any
circumstances be reissued; and the Corporation may from time to time take such
appropriate corporate action as may be necessary to reduce accordingly the
number of authorized shares of Class B Convertible Preferred Stock, Class C
Convertible Preferred Stock and Class D Convertible Preferred Stock.

                                    E.      7E.      Delay of Redemption.  
Notwithstanding paragraph 7A hereof, the Corporation shall not be required to
redeem any shares of Class B Convertible Preferred Stock, Class C Convertible
Preferred Stock and Class D Convertible Preferred Stock on any Redemption Date
if the cost to the Corporation of such redemption would be greater than one-half
of the Corporation's available average cash working capital balance for the
quarter immediately preceding such Redemption 



   100



Date. If a redemption is delayed pursuant to this Paragraph 7E, the Corporation
shall redeem the shares to be so redeemed within 120 days of such Redemption
Date.

                           VIII.    Amendments.  No provision of these terms of
the Preferred Stock may be amended, modified or waived without the written
consent or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Class B Convertible Preferred Stock and Class C
Convertible Preferred Stock and at least a majority of the then outstanding
shares of Class D Convertible Preferred Stock; provided, however, that so long
as TTC Ventures holds at least two percent (2%) of the outstanding shares of
Common Stock of the Corporation (assuming the conversion of all outstanding
Preferred Stock), no amendment shall be made to the provisions of Section 2C
relating to the representation of the holders of Class D Convertible Preferred
Stock without the consent of TTC Ventures.

                  1. Number of Shares. There shall be three classes of Preferred

shares, the Class B Convertible Preferred Stock shall consist of 2,151,420
shares, and the Class C Convertible Preferred Stock shall consist of 3,188,889
shares. The Class A Convertible Preferred Stock, the Class B Convertible

including, but not limited to actions amending the Certificate of Incorporation
of the Corporation to increase the number of authorized shares of Common Stock.
Each share of Preferred Stock shall entitle the holder thereof to such number of
votes per share on each such action as shall equal the number of shares of
Common Stock (including fractions of a share) into which each share of Preferred
Stock is then convertible.

                           B. 2B. Board Size. The Corporation shall not, without
         the written consent or affirmative vote of the holders of at least
         two-thirds of the then outstanding shares of Class B Convertible
         Preferred Stock and Class C Convertible Preferred Stock, consenting or
         voting (as the case may be) as a single class, given in writing or by
         vote at a meeting, increase the maximum number of directors
         constituting the Board of Directors to a number in excess of six.

                           C. 2C. Board Seats. So long as the outstanding Class
         A Convertible Preferred Stock represents at least 10% of the
         outstanding Common Stock of the Corporation (assuming the conversion of
         all outstanding Preferred Stock), the holders of the Class A
         Convertible Preferred Stock, voting as a separate class, shall be
         entitled to elect one director of the Corporation. So long as the
         outstanding Class B Convertible Preferred Stock represents at least 5%
         of the outstanding Common Stock of the Corporation (assuming the

         be entitled to elect one director of the Corporation (the "Class B
         Director"). So long as the outstanding Class C Convertible Preferred
         Stock represents at least 5% of the outstanding Common Stock of the
         Corporation (assuming the conversion of all outstanding Preferred
         Stock), the holders of the Class C Convertible Preferred Stock, voting
         as a separate class, shall be entitled to elect one director of the
         Corporation (the "Class C Director"). The holders of the Common Stock,

         Preferred Stock, voting as separate classes, and a majority vote of the

         Stock or jointly by the holders of the Class C Convertible Preferred
         Stock, the Class B Convertible Preferred Stock, and the Common Stock,
         the presence in person or by proxy (or the written consent) of the

         Stock, or Class C Convertible Preferred Stock shall be filled only by
         vote or written consent of the holders of the Class A Convertible

         Convertible Preferred Stock, respectively; a vacancy in any
         directorship elected by the holders of the Common Stock shall be filled
         only by vote or written consent of the holders of the Common Stock; and

                           A. 4A. Upon any liquidation, dissolution or winding
         up of the Corporation, whether voluntary or involuntary, the holders of
         the shares of Class B Convertible Preferred Stock and Class C
         Convertible Preferred Stock shall first be entitled, before any
         distribution or payment is made upon any stock ranking on liquidation
         junior to the Class B Convertible Preferred Stock and the Class C
         Convertible Preferred Stock, to be paid an amount equal to $0.76 and
         $1.44 per share, respectively, plus, in the case of each share of Class
         B Convertible Preferred Stock, an amount equal to all Class B Accruing
         Dividends unpaid thereon (whether or not declared) and any other
         dividends declared but unpaid thereon, and in the case of each share of
         Class C Convertible Preferred Stock, an amount equal to all Class C
         Accruing Dividends unpaid thereon (whether or not declared) and any
         other dividends declared but unpaid thereon, computed to the date
         payment thereof is made available, such amount payable with respect to
         one share of Class B Convertible Preferred Stock being sometimes
         referred to as the "Class B Liquidation Preference Payment," such
         amount payable with respect to one share of Class C Convertible
         Preferred Stock being sometimes referred to as the "Class C Liquidation
         Preference Payment," and with respect to all shares of Class B
         Convertible Preferred Stock and Class C Convertible Preferred Stock
         being sometimes referred to as the "Class B and Class C Liquidation

         up of the Corporation, whether voluntary or involuntary, the assets to
         be distributed among the holders of Class B Convertible Preferred Stock
         and Class C Convertible Preferred Stock shall be insufficient to permit
         payment in full to the holders of Class B Convertible Preferred Stock
         and Class C Convertible Preferred Stock of the Liquidation Preference
         Payments, then the entire assets of the Corporation to be so
         distributed shall be distributed ratably, on an as-converted basis,
         among the holders of Class B Convertible Preferred Stock and Class C
         Convertible Stock.

                           B. 4B. Upon any liquidation, dissolution or winding
         up of the Corporation, whether voluntary or involuntary, after the
         holders of Class B Convertible Preferred Stock and Class C Convertible
         Preferred Stock shall have been paid in full the amounts to which they
         shall be entitled pursuant to paragraph 4A, the holders of the shares
         of Class A Convertible Preferred Stock shall then be entitled, before
         any distribution or payment is made upon any stock ranking on
         liquidation junior to the Class A Convertible Preferred Stock, to be
         paid an amount equal to $.32 per share plus, in the case of each share,
         an amount equal to all Class A Accruing Dividends unpaid thereon

         Convertible Preferred Stock being sometimes referred to as the "Class A
         Liquidation Preference Payment" and with respect to all shares of Class

         Payments and the Class B and Class C Liquidation Preference Payments
         are sometimes referred to herein collectively as the "Liquidation
         Preference Payments." If upon such liquidation, dissolution or winding
         up of the Corporation, whether voluntary or involuntary, the assets to
         be distributed among the holders of Class A Convertible 



   106



         Preferred Stock shall be insufficient to permit payment in full to the
         holders of Class A Convertible Preferred Stock of the Class A
         Liquidation Preference Payments, then the entire remaining assets of
         the Corporation to be so distributed shall be distributed ratably among
         the holders of Class A Convertible Preferred Stock.

                           C. 4C. Upon any such liquidation, dissolution or
         winding up of the Corporation, immediately after the holders of Class B
         Convertible Preferred Stock, Class C Convertible Preferred Stock, and
         Class A Convertible Preferred Stock shall have been paid in full their
         respective Liquidation Preference Payments, the remaining net assets of
         the Corporation available for distribution shall be distributed ratably
         among the holders of Preferred Stock and Common Stock (with each share
         of Preferred Stock being deemed, for such purpose, to be equal to the
         number of shares of Common Stock (including fractions of a share) into
         which such share of Preferred Stock is convertible immediately prior to
         the close of business on the business day fixed for such distribution).
         Unless otherwise agreed by holders of at least two-thirds of the Class
         B Convertible Preferred Stock and Class C Convertible Preferred Stock,
         voting as separate classes, the consolidation or merger of the
         Corporation into or with any other entity or entities which results in
         the exchange of outstanding shares of the Corporation for securities or
         other consideration issued or paid or caused to be issued or paid by
         any such entity or affiliate thereof (other than a merger to
         reincorporate the Corporation in a different jurisdiction), and the
         sale, lease, abandonment, transfer or other disposition by the
         Corporation of all or substantially all its assets (each such event a
         "Liquidity Event"), shall be deemed to be a liquidation, dissolution or
         winding up of the Corporation within the meaning of the provisions of
         this paragraph 4.

                           D. 4D. Written notice of such liquidation,
         dissolution or winding up, stating a payment date, the amount of the
         Liquidation Preference Payments and the place where said Liquidation
         Preference Payments shall be payable, shall be delivered in person,
         mailed by certified or registered mail, return receipt requested, or
         sent by telecopier or telex, not less than 20 days prior to the payment
         date stated therein, to the holders of record of Preferred Stock, such
         notice to be addressed to each such holder at its address as shown by
         the records of the Corporation. For purposes hereof, the Common Stock
         shall rank on liquidation junior to the Class A Convertible Preferred
         Stock, the Class B Convertible Preferred Stock, and the Class C
         Convertible Preferred Stock.

                  5. Restrictions. At any time when shares of Class B
Convertible Preferred Stock or Class C Convertible Preferred Stock are
outstanding, except where the vote or written consent of the holders of a
greater number of shares of the Corporation is required by law or by the
Certificate of Incorporation, and in addition to any other vote required by law
or the Certificate of Incorporation, without the approval of the holders of at
least a majority of the then outstanding shares of both the Class B Convertible
Preferred Stock and Class C Preferred Stock, consenting or voting (as the case
may be) as separate classes, given in writing or by vote at a meeting, the
Corporation will not:



   107




                           A. 5A. Create or authorize the creation of any
         additional class or series of shares of stock unless the same ranks
         junior to the Class B Convertible Preferred Stock and the Class C
         Convertible Preferred Stock as to the distribution of assets on the
         liquidation, dissolution or winding up of the Corporation, redemption
         and the payment of dividends, or increase the authorized amount of the
         Class B Convertible Preferred Stock or the Class C Convertible
         Preferred Stock or increase the authorized amount of any additional
         class or series of shares of stock unless the same ranks junior to the
         Class B Convertible Preferred Stock and the Class C Convertible
         Preferred Stock as to the distribution of assets on the liquidation,
         dissolution or winding up of the Corporation, redemption and the
         payment of dividends, or create or authorize any obligation or security
         convertible into shares of Class B Convertible Preferred Stock or Class
         C Convertible Preferred Stock or into shares of any other class or
         series of stock unless the same ranks junior to the Class B Convertible
         Preferred Stock and the Class C Convertible Preferred Stock as to the
         distribution of assets on the liquidation, dissolution or winding up of
         the Corporation, redemption and the payment of dividends, whether any
         such creation, authorization or increase shall be by means of amendment
         to the Certificate of Incorporation or by merger, consolidation or
         otherwise; provided, that such consent shall not be unreasonably
         withheld for the creation or issuance of an additional class or series
         of shares ranking senior to the Class B Convertible Preferred Stock and
         the Class C Convertible Preferred Stock as to the distribution of
         assets on the liquidation, dissolution or winding up of the
         Corporation, redemption and the payment of dividends (a "Senior
         Security"), but provided further, that if, within a reasonable time of
         the submission of a proposal for the issuance of a Senior Security,
         information comes to light indicating that such consent was withheld
         solely or primarily for the purpose of negotiating the price of an
         additional investment by the holders of the Class B Convertible
         Preferred Stock and/or the Class C Convertible Preferred Stock, then
         such consent shall be deemed to have been unreasonably withheld for
         purposes of this subparagraph 5A.

                           B. 5B. Consent to any liquidation, dissolution or
         winding up of the Corporation or consolidate or merge into or with any
         other entity or entities or sell, lease, abandon, transfer or otherwise
         dispose of all or substantially all its assets, unless such action
         would result in an annualized return to the holders of the Class B
         Convertible Preferred Stock and the Class C Convertible Preferred Stock
         of at least 30%;

                           C. 5C. Amend, alter or repeal its Certificate of
         Incorporation or ByLaws if the effect would be materially detrimental
         or adverse in any manner with respect to the rights of the holders of
         the Class B Convertible Preferred Stock and/or the Class C Convertible
         Preferred Stock;

                           D. 5D. Purchase or set aside any sums for the
         purchase of, or pay any dividend or make any distribution on, any
         shares of stock other than the Class B Convertible Preferred Stock and
         the Class C Convertible Preferred Stock, except for (i) Class A
         Accruing Dividends, (ii) dividends or other distributions payable on
         the Common Stock solely in the form of additional shares of Common
         Stock, and (iii) the purchase of shares of Common Stock from former
         employees of the Corporation who acquired such 



   108



         shares directly from the Corporation, if each such purchase is made
         pursuant to contractual rights held by the Corporation relating to the
         termination of employment of such former employee and the purchase
         price (except in the case of agreements executed prior to July 12,
         1996) does not exceed the original issue price paid by such former
         employee to the Corporation for such shares; or

                           E.       5E.     Redeem or otherwise acquire any
         shares of Class B Convertible Preferred Stock or Class C Convertible
         Preferred Stock except as expressly authorized in paragraph 7 hereof or
         pursuant to a purchase offer made pro rata to all holders of the shares
         of Class B Convertible Preferred Stock and Class C Convertible
         Preferred Stock on the basis of the aggregate number of outstanding
         shares of Class B Convertible Preferred Stock and/or Class C
         Convertible Preferred Stock then held by each such holder.

                  6.       Conversions.  The holders of shares of Preferred 
Stock shall have the following conversion rights:

                           A. 6A. Right to Convert. Subject to the terms and
         conditions of this paragraph 6, the holder of any share or shares of
         Preferred Stock shall have the right, at its option at any time, to
         convert any such shares of Preferred Stock into such number of fully
         paid and nonassessable shares of Common Stock as is obtained by (i)
         multiplying the number of shares of Preferred Stock so to be converted
         by the Original Purchase Price of such share (which shall be $0.32 in
         the case of the Class A Convertible Preferred Stock, $.76 in the case
         of Class B Convertible Preferred Stock, and $1.44 in the case of Class
         C Convertible Preferred Stock) and (ii) dividing the result by the
         conversion price of the Original Purchase Price of such share or, in
         case an adjustment of such price has taken place pursuant to the
         further provisions of this paragraph 6, then by the conversion price as
         last adjusted and in effect at the date any share or shares of
         Preferred Stock are surrendered for conversion (such price, or such
         price as last adjusted, being referred to as the "Conversion Price,"
         with respect to the Class B Convertible Preferred Stock, the "Class B
         Conversion Price," and, with respect to the Class C Convertible
         Preferred Stock, the "Class C Conversion Price"). Such rights of
         conversion shall be exercised by the holder thereof by giving written
         notice that the holder elects to convert a stated number of shares of
         Preferred Stock into Common Stock and by surrender of a certificate or
         certificates for the shares so to be converted to the Corporation at
         its principal office (or such other office or agency of the Corporation
         as the Corporation may designate by notice in writing to the holders of
         the Preferred Stock) at any time during its usual business hours on the
         date set forth in such notice, together with a statement of the name or
         names (with address) in which the certificate or certificates for
         shares of Common Stock shall be issued.

                           B. 6B. Issuance of Certificates; Time Conversion
         Effected. Promptly after the receipt of the written notice referred to
         in subparagraph 6A and surrender of the certificate or certificates for
         the share or shares of Preferred Stock to be converted, the Corporation
         shall issue and deliver, or cause to be issued and delivered, to the
         holder, registered in such name or names as such holder may direct, a
         certificate




   109


         or certificates for the number of whole shares of Common Stock issuable
         upon the conversion of such share or shares of Preferred Stock. To the
         extent permitted by law, such conversion shall be deemed to have been
         effected and the Conversion Price shall be determined as of the close
         of business on the date on which such written notice shall have been
         received by the Corporation and the certificate or certificates for
         such share or shares shall have been surrendered as aforesaid, and at
         such time the rights of the holder of such share or shares of Preferred
         Stock shall cease, and the person or persons in whose name or names any
         certificate or certificates for shares of Common Stock shall be
         issuable upon such conversion shall be deemed to have become the holder
         or holders of record of the shares represented thereby.

                           C. 6C. Fractional Shares; Dividends; Partial
         Conversion. No fractional shares shall be issued upon conversion of
         Preferred Stock into Common Stock and no payment or adjustment shall be
         made upon any conversion on account of any cash dividends on the Common
         Stock issued upon such conversion. At the time of each conversion, the
         Corporation shall pay in cash an amount equal to all dividends,
         excluding Accruing Dividends, accrued and unpaid on the shares of
         Preferred Stock surrendered for conversion to the date upon which such
         conversion is deemed to take place as provided in subparagraph 6B. In
         case the number of shares of Preferred Stock represented by the
         certificate or certificates surrendered pursuant to subparagraph 6A
         exceeds the number of shares converted, the Corporation shall, upon
         such conversion, execute and deliver to the holder, at the expense of
         the Corporation, a new certificate or certificates for the number of
         shares of Preferred Stock represented by the certificate or
         certificates surrendered which are not to be converted. If any
         fractional share of Common Stock would, except for the provisions of
         the first sentence of this subparagraph 6C, be delivered upon such
         conversion, the Corporation, in lieu of delivering such fractional
         share, shall pay to the holder surrendering the Preferred Stock for
         conversion an amount in cash equal to the current market price of such
         fractional share as determined in good faith by the Board of Directors
         of the Corporation.

                           D. 6D. Adjustment of Price Upon Issuance of Common
         Stock. Except as provided in subparagraph 6E, if and whenever the
         Corporation shall issue or sell, or is, in accordance with
         subparagraphs 6D(1) through 6D(7), deemed to have issued or sold, any
         shares of Common Stock for a consideration per share less than (i) the
         Class B Conversion Price in effect immediately prior to the time of
         such issue or sale, or (ii) the Class C Conversion Price in effect
         immediately prior to the time of such issue or sale, then, forthwith
         upon such issue or sale, the Class B Conversion Price and/or the Class
         C Conversion Price, as the case may be, shall be reduced to the price
         determined by dividing (i) an amount equal to the sum of (a) the number
         of shares of Common Stock outstanding immediately prior to such issue
         or sale multiplied by the then existing Class B Conversion Price or the
         then existing Class C Conversion Price, as the case may be, and (b) the
         consideration, if any, received by the Corporation upon such issue or
         sale, by (ii) the total number of shares of Common Stock outstanding
         immediately after such issue or sale.



   110



                  For purposes of this subparagraph 6D, the following
subparagraphs 6D(1) to 6D(7) shall also be applicable:

                           1. 6D(1) Issuance of Rights or Options. In case at
         any time the Corporation shall in any manner grant (whether directly or
         by assumption in a merger or otherwise) any warrants or other rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or security convertible into or exchangeable
         for Common Stock (such warrants, rights or options being called
         "Options" and such convertible or exchangeable stock or securities
         being called "Convertible Securities") whether or not such Options or
         the right to convert or exchange any such Convertible Securities are
         immediately exercisable, and the price per share for which Common Stock
         is issuable upon the exercise of such Options or upon the conversion or
         exchange of such Convertible Securities (determined by dividing (i) the
         total amount, if any, received or receivable by the Corporation
         as consideration for the granting of such Options, plus the minimum
         aggregate amount of additional consideration payable to the Corporation
         upon the exercise of all such Options, plus, in the case of such
         Options which relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (ii) the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such Options) shall be less than the Class B Conversion Price and/or
         the Class C Conversion Price in effect immediately prior to the time of
         the granting of such Options, then the total maximum number of shares
         of Common Stock issuable upon the exercise of such Options or upon
         conversion or exchange of the total maximum amount of such Convertible
         Securities issuable upon the exercise of such Options shall be deemed
         to have been issued for such price per share as of the date of granting
         of such Options or the issuance of such Convertible Securities and
         thereafter shall be deemed to be outstanding. Except as otherwise
         provided in subparagraph 6D(3), no adjustment of the Class B Conversion
         Price and/or the Class C Conversion Price shall be made upon the actual
         issue of such Common Stock or of such Convertible Securities upon
         exercise of such Options or upon the actual issue of such Common Stock
         upon conversion or exchange of such Convertible Securities.

                           2. 6D(2) Issuance of Convertible Securities. In case
         the Corporation shall in any manner issue (whether directly or by
         assumption in a merger or otherwise) or sell any Convertible
         Securities, whether or not the rights to exchange or convert any such
         Convertible Securities are immediately exercisable, and the price per
         share for which Common Stock is issuable upon such conversion or
         exchange (determined by dividing (i) the total amount received or
         receivable by the Corporation as consideration for the issue or sale of
         such Convertible Securities, plus the minimum aggregate amount of
         additional consideration, if any, payable to the Corporation upon the
         conversion or exchange thereof, by (ii) the total maximum number of
         shares of Common Stock issuable upon the conversion or exchange of all
         such Convertible Securities) shall be less than the Class B Conversion
         Price and/or the Class C Conversion Price in effect immediately prior
         to the time of such issue or sale, then the total maximum number of
         shares of Common 


   111



         Stock issuable upon conversion or exchange of all such Convertible
         Securities shall be deemed to have been issued for such price per share
         as of the date of the issue or sale of such Convertible Securities and
         thereafter shall be deemed to be outstanding, provided that (a) except
         as otherwise provided in subparagraph 6D(3), no adjustment of the Class
         B Conversion Price and/or the Class C Conversion Price shall be made
         upon the actual issue of such Common Stock upon conversion or exchange
         of such Convertible Securities and (b) if any such issue or sale of
         such Convertible Securities is made upon exercise of any Options to
         purchase any such Convertible Securities for which adjustments of the
         Class B Conversion Price and/or the Class C Conversion Price have been
         or are to be made pursuant to other provisions of this subparagraph 6D,
         no further adjustment of the Class B Conversion Price and/or the Class
         C Conversion Price shall be made by reason of such issue or sale.

                           3.       6D(3)   Change in Option Price or Conversion
         Rate. Upon the happening of any of the following events, namely, if the
         purchase price provided for in any Option referred to in subparagraph
         6D(1), the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         subparagraph 6D(1) or 6D(2), or the rate at which Convertible
         Securities referred to in subparagraph 6D(1) or 6D(2) are convertible
         into or exchangeable for Common Stock shall change at any time
         (including, but not limited to, changes under or by reason of
         provisions designed to protect against dilution), the Class B
         Conversion Price and/or the Class C Conversion Price in effect at the
         time of such event shall forthwith be readjusted to the Class B
         Conversion Price or Class C Conversion Price, as the case may be, which
         would have been in effect at such time had such Options or Convertible
         Securities still outstanding provided for such changed purchase price,
         additional consideration or conversion rate, as the case may be, at the
         time initially granted, issued or sold, but only if as a result of such
         adjustment the Class B Conversion Price and/or the Class C Conversion
         Price then in effect hereunder is thereby reduced; and on the
         termination or expiration of any such Option or any such right to
         convert or exchange such Convertible Securities, the Class B Conversion
         Price and/or the Class C Conversion Price then in effect hereunder
         shall forthwith be increased to the Class B Conversion Price or Class C
         Conversion Price, as the case may be, which would have been in effect
         at the time of such termination or expiration had such Option or
         Convertible Securities, to the extent outstanding immediately prior to
         such termination or expiration, never been issued.

                           4. 6D(4) Stock Dividends. In case the Corporation
         shall declare a dividend or make any other distribution upon any stock
         of the Corporation (other than the Common Stock) payable in Common
         Stock, Options or Convertible Securities, then any Common Stock,
         Options or Convertible Securities, as the case may be, issuable in
         payment of such dividend or distribution shall be deemed to have been
         issued or sold without consideration.

                           5. 6D(5) Consideration for Stock. In case any shares
         of Common Stock, Options or Convertible Securities shall be issued or
         sold for cash, the consideration received therefor shall be deemed to
         be the amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions 



   112



         or concessions paid or allowed by the Corporation in connection
         therewith. In case any shares of Common Stock, Options or Convertible
         Securities shall be issued or sold for a consideration other than cash,
         the amount of the consideration other than cash received by the
         Corporation shall be deemed to be the fair value of such consideration
         as determined in good faith by the Board of Directors of the
         Corporation, without deduction of any expenses incurred or any
         underwriting commissions or concessions paid or allowed by the
         Corporation in connection therewith. In case any Options shall be
         issued in connection with the issue and sale of other securities of the
         Corporation, together comprising one integral transaction in which no
         specific consideration is allocated to such Options by the parties
         thereto, such Options shall be deemed to have been issued for such
         consideration as determined in good faith by the Board of Directors of
         the Corporation.

                           6. 6D(6) Record Date. In case the Corporation shall
         take a record of the holders of its Common Stock for the purpose of
         entitling them (i) to receive a dividend or other distribution payable
         in Common Stock, Options or Convertible Securities or (ii) to
         subscribe for or purchase Common Stock, Options or Convertible
         Securities, then such record date shall be deemed to be the date of the
         issue or sale of the shares of Common Stock deemed to have been issued
         or sold upon the declaration of such dividend or the making of such
         other distribution or the date of the granting of such right of
         subscription or purchase, as the case may be.

                           7. 6D(7) Treasury Shares. The number of shares of
         Common Stock outstanding at any given time shall not include shares
         owned or held by or for the account of the Corporation, and the
         disposition of any such shares shall be considered an issue or sale of
         Common Stock for the purpose of this subparagraph 6D.

                           E. 6E. Certain Issues of Common Stock Excepted.
         Anything herein to the contrary notwithstanding, the Corporation shall
         not be required to make any adjustment of the Class B Conversion Price
         or the Class C Conversion Price in the case of the issuance from and
         after the date of filing of these terms of the Preferred Stock of up to
         an aggregate of 1,540,000 shares (appropriately adjusted to reflect the
         occurrence of any event described in subparagraphs 6E or 6F) (the
         "Reserved Shares") of Common Stock to directors, officers, employees or
         consultants of the Corporation in connection with their service as
         directors of the Corporation, their employment by the Corporation or
         their retention as consultants by the Corporation (provided that the
         number of Reserved Shares may be increased (a) prior to July 12, 1997,
         with the approval of a majority of the Board of Directors including the
         Class B Director and the Class C Director and (b) after July 12, 1997,
         with the approval of either (i) a majority of the Board of Directors
         including the Class B Director and the Class C Director or (ii) all
         directors other than the Class B Director or the Class C Director),
         plus such number of shares of Common Stock which are repurchased by the
         Corporation from such persons after such date pursuant to contractual
         rights held by the Corporation and at repurchase prices not exceeding
         the respective original purchase prices paid by such persons to the
         Corporation therefor.

                           F. 6F. Subdivision or Combination of Common Stock. In
         case the Corporation shall at any time subdivide (by any stock split,
         stock dividend or otherwise) 



   113



         its outstanding shares of Common Stock into a greater number of shares,
         the Conversion Price in effect immediately prior to such subdivision
         shall be proportionately reduced, and, conversely, in case the
         outstanding shares of Common Stock shall be combined into a smaller
         number of shares, the Conversion Price in effect immediately prior to
         such combination shall be proportionately increased. In the case of any
         such subdivision, no further adjustment shall be made pursuant to
         subparagraph 6D by reason thereof.

                           G. 6G. Reorganization or Reclassification. If any
         capital reorganization or reclassification of the capital stock of the
         Corporation shall be effected in such a way that holders of Common
         Stock shall be entitled to receive stock, securities or assets with
         respect to or in exchange for Common Stock, then, as a condition of
         such reorganization or reclassification, lawful and adequate provisions
         shall be made whereby each holder of a share or shares of Preferred
         Stock shall thereupon have the right to receive, upon the basis and
         upon the terms and conditions specified herein and in lieu of the
         shares of Common Stock immediately theretofore receivable upon the
         conversion of such share or shares of Preferred Stock, such shares of
         stock, securities or assets as may be issued or payable with respect to
         or in exchange for a number of outstanding shares of such Common Stock
         equal to the number of shares of such Common Stock immediately
         theretofore receivable upon such conversion had such reorganization or
         reclassification not taken place, and in any such case appropriate
         provisions shall be made with respect to the rights and interests of
         such holder to the end that the provisions hereof (including without
         limitation provisions for adjustments of the Conversion Price) shall
         thereafter be applicable, as nearly as may be, in relation to any
         shares of stock, securities or assets thereafter deliverable upon the
         exercise of such conversion rights.

                           H. 6H. Notice of Adjustment. Upon any adjustment of
         the Conversion Price, then and in each such case the Corporation shall
         give written notice thereof, by delivery in person, certified or
         registered mail, return receipt requested, telecopier or telex,
         addressed to each holder of shares of Preferred Stock at the address of
         such holder as shown on the books of the Corporation, which notice
         shall state the Conversion Price resulting from such adjustment,
         setting forth in reasonable detail the method upon which such
         calculation is based.

                           I.       6I.     Other Notices.  In case at any time:

                                             (1)     the Corporation shall 
         declare any dividend upon its Common Stock payable in cash or stock or
         make any other distribution to the holders of its Common Stock;

                                             (2)     the Corporation shall offer
         for subscription pro rata to the holders of its Common Stock any
         additional shares of stock of any class or other rights;

                                             (3)     there shall be any capital
         reorganization or reclassification of the capital stock of the
         Corporation, or a consolidation or merger of the 



   114



         Corporation with or into another entity or entities, or a sale, lease,
         abandonment, transfer or other disposition of all or substantially all
         its assets; or

                                             (4)     there shall be a voluntary
         or involuntary dissolution, liquidation or winding up of the
         Corporation;

  then, in any one or more of said cases, the Corporation shall give, by
delivery in person, certified or registered mail, return receipt requested,
telecopier or telex, addressed to each holder of any shares of Preferred Stock
at the address of such holder as shown on the books of the Corporation, (a) at
least 20 days' prior written notice of the date on which the books of the
Corporation shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of any such reorganization, reclassification, consolidation, merger,
disposition, dissolution, liquidation or winding up and (b) in the case of any
such reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding up, at least 20 days' prior written notice
of the date when the same shall take place. Such notice in accordance with the
foregoing clause (a) shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto and such notice in accordance with the foregoing
clause (b) shall also specify the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, disposition, dissolution, liquidation or winding up, as the case may be.

                           J. 6J. Stock to be Reserved. The Corporation will at
         all times reserve and keep available out of its authorized Common
         Stock, solely for the purpose of issuance upon the conversion of
         Preferred Stock as herein provided, such number of shares of Common
         Stock as shall then be issuable upon the conversion of all outstanding
         shares of Preferred Stock. The Corporation covenants that all shares of
         Common Stock which shall be so issued shall be duly and validly issued
         and fully paid and nonassessable and free from all taxes, liens and
         charges with respect to the issue thereof, and, without limiting the
         generality of the foregoing, the Corporation covenants that it will
         from time to time take all such action as may be requisite to assure
         that the par value per share of the Common Stock is at all times equal
         to or less than the Conversion Price in effect at the time. The
         Corporation will take all such action as may be necessary to assure
         that all such shares of Common Stock may be so issued without violation
         of any applicable law or regulation, or of any requirement of any
         national securities exchange upon which the Common Stock may be listed.
         The Corporation will not take any action which results in any
         adjustment of the Conversion Price if the total number of shares of
         Common Stock issued and issuable after such action upon conversion of
         the Preferred Stock would exceed the total number of shares of Common
         Stock then authorized by the Certificate of Incorporation.

                           K.       6K.     No Reissuance of Preferred Stock. 
         Shares of Preferred Stock which are converted into shares of Common
         Stock as provided herein shall not be reissued.



   115




                           L. 6L. Issue Tax. The issuance of certificates for
         shares of Common Stock upon conversion of Preferred Stock shall be made
         without charge to the holders thereof for any issuance tax in respect
         thereof, provided that the Corporation shall not be required to pay any
         tax which may be payable in respect of any transfer involved in the
         issuance and delivery of any certificate in a name other than that of
         the holder of the Preferred Stock which is being converted.

                           M. 6M. Closing of Books. The Corporation will at no
         time close its transfer books against the transfer of any Preferred
         Stock or of any shares of Common Stock issued or issuable upon the
         conversion of any shares of Preferred Stock in any manner which
         interferes with the timely conversion of such Preferred Stock, except
         as may otherwise be required to comply with applicable securities laws.

                           N. 6N. Definition of Common Stock. As used in this
         paragraph 6, the term "Common Stock" shall mean and include the
         Corporation's authorized Common Stock, par value $.001 per share, as
         constituted on the date of filing of these terms of the Preferred
         Stock, and shall also include any capital stock of any class of the
         Corporation thereafter authorized which shall not be limited to a fixed
         sum or percentage in respect of the rights of the holders thereof to
         participate in dividends or in the distribution of assets upon the
         voluntary or involuntary liquidation, dissolution or winding up of the
         Corporation; provided that the shares of Common Stock receivable upon
         conversion of shares of Preferred Stock shall include only shares
         designated as Common Stock of the Corporation on the date of filing of
         this instrument, or in case of any reorganization or reclassification
         of the outstanding shares thereof, the stock, securities or assets
         provided for in subparagraph 6G.

                           O. 6O. Mandatory Conversion. If at any time (i) the
         Corporation shall effect a firm commitment underwritten public offering
         of shares of Common Stock in which (A) the aggregate price paid for
         such shares by the public shall be at least $15,000,000 and (B) the
         price paid by the public for such shares shall be at least $4.32 per
         share (appropriately adjusted to reflect the occurrence of any event
         described in subparagraph 6F), or (ii) a Liquidity Event shall occur in
         which (a) the holders of shares of any class of Preferred Stock would
         receive consideration for all of such shares (as if converted to Common
         Stock) of at least four (4) times the original purchase price of such
         shares (for example, at least $1.28 for (i) each share of Class A
         Convertible Preferred Stock or (ii) all shares of Common Stock into
         which such share of Class A Convertible Preferred Stock is convertible;
         at least $3.04 for (i) each share of Class B Convertible Preferred
         Stock or (ii) all shares of Common Stock into which such share of Class
         B Convertible Preferred Stock is convertible; or at least $5.76 for (i)
         each share of Class C Convertible Preferred Stock or (ii) all shares of
         Common Stock into which such share of Class C Convertible Preferred
         Stock is convertible), then effective upon the closing of the sale of
         such shares by the Corporation pursuant to such public offering or
         immediately prior to the occurrence of such Liquidity Event, as the
         case may be, all outstanding shares of Preferred Stock (in the case of
         a public offering) or such class of Preferred Stock (in the case of a
         Liquidity Event) shall automatically convert to shares of Common Stock
         on 



   116



         the basis set forth in this paragraph 6. Holders of shares of Preferred
         Stock so converted may deliver to the Corporation at its principal
         office (or such other office or agency of the Corporation as the
         Corporation may designate by notice in writing to such holders) during
         its usual business hours, the certificate or certificates for the
         shares so converted. As promptly as practicable thereafter, the
         Corporation shall issue and deliver to such holder a certificate or
         certificates for the number of whole shares of Common Stock to which
         such holder is entitled, together with any cash dividends and payment
         in lieu of fractional shares to which such holder may be entitled
         pursuant to subparagraph 6C. Until such time as a holder of shares of
         Preferred Stock shall surrender his or its certificates therefor as
         provided above, such certificates shall be deemed to represent the
         shares of Common Stock to which such holder shall be entitled upon the
         surrender thereof.

                  7.       Redemption.  The shares of Class B and Class C 
Convertible Preferred Stock shall be redeemed as follows:

                           A. 7A. Mandatory Redemption. On June 30, 2001, and on
         each of the next two anniversaries thereafter (the "Redemption Dates,"
         and each a "Redemption Date"), the Corporation shall redeem any
         outstanding shares of Class B and Class C Convertible Preferred Stock
         according to the percentages listed below:



   117






                                  Percentage of Shares of
                                Class B and Class C Convertible
                                Preferred Stock then
Date of Redemption              Outstanding to be Redeemed

  June 30, 2001                   33-1/3% of all the shares of Class B and Class
                                C Convertible Preferred Stock Outstanding on 
                                June 30, 2001

  June 30, 2002                   50% of all the shares of Class B and Class C
                                Convertible Preferred Stock outstanding on June
                                30, 2002

  June 30, 2003                   100% of all the shares of Class B and Class C

                                30, 2003

                           B. 7B. Redemption Price and Payment. The shares of
         Class B and Class C Convertible Preferred Stock to be redeemed on any
         Redemption Date shall be redeemed by paying for each share in cash an
         amount equal to $0.76 and $1.44 per share, respectively, plus, in the
         case of each share, an amount equal to all dividends, excluding
         Accruing Dividends, declared but unpaid thereon, computed to such
         Redemption Date, such amount being referred to as the "Redemption
         Price". Such payment shall be made in full on the applicable Redemption
         Date to the holders entitled thereto.

                           C. 7C. Redemption Mechanics. At least 20 but not more
         than 30 days prior to each Redemption Date, written notice (the
         "Redemption Notice") shall be given by the Corporation by delivery in
         person, certified or registered mail, return receipt requested,
         telecopier or telex, to each holder of record (at the close of business
         on the business day next preceding the day on which the Redemption
         Notice is given) of shares of Class B Convertible Preferred Stock and
         Class C Convertible Preferred Stock notifying such holder of the
         redemption and specifying the Redemption Price, such Redemption Date,
         the number of shares of Class B Convertible Preferred Stock and/or
         Class C Convertible Preferred Stock to be redeemed from such holder
         (computed on a pro rata basis in accordance with the number of such
         shares held by all holders thereof) and the place where said Redemption
         Price shall be payable. The Redemption Notice shall be addressed to
         each holder at his address as shown by the records of the Corporation.
         From and after the close of business on a Redemption Date, unless there
         shall have been a default in the payment of the Redemption Price, all
         rights of holders of shares of Class B Convertible Preferred Stock and
         Class C Convertible Preferred Stock (except the right to receive the
         Redemption Price) shall cease with respect to the shares to be redeemed
         on such Redemption Date, and such shares shall not thereafter be
         transferred on the books 



   118



         of the Corporation or be deemed to be outstanding for any purpose
         whatsoever. If the funds of the Corporation legally available for
         redemption of shares of Class B Convertible Preferred Stock and Class C
         Convertible Preferred Stock on a Redemption Date are insufficient to
         redeem the total number of shares of Class B Convertible Preferred
         Stock and Class C Convertible Preferred Stock to be redeemed on such
         Redemption Date, the holders of such shares shall share ratably in any
         funds legally available for redemption of such shares according to the
         respective amounts which would be payable to them if the full number of
         shares to be redeemed on such Redemption Date were actually redeemed.
         The shares of Class B Convertible Preferred Stock and Class C
         Convertible Preferred Stock required to be redeemed but not so redeemed
         shall remain outstanding and entitled to all rights and preferences
         provided herein. At any time thereafter when additional funds of the
         Corporation are legally available for the redemption of such shares of
         Class B Convertible Preferred Stock and Class C Convertible Preferred
         Stock, such funds will be used, at the end of the next succeeding
         fiscal quarter, to redeem the balance of such shares, or such portion
         thereof for which funds are then legally available, on the basis set
         forth above.

                           D. 7D. Redeemed or Otherwise Acquired Shares to be
         Retired. Any shares of Class B Convertible Preferred Stock and Class C
         Convertible Preferred Stock redeemed pursuant to this paragraph 7 or
         otherwise acquired by the Corporation in any manner whatsoever shall be
         canceled and shall not under any circumstances be reissued; and the
         Corporation may from time to time take such appropriate corporate
         action as may be necessary to reduce accordingly the number of
         authorized shares of Class B Convertible Preferred Stock and Class C
         Convertible Preferred Stock.

                           E. 7E. Delay of Redemption. Notwithstanding paragraph
         7A hereof, the Corporation shall not be required to redeem any shares
         of Class B Convertible Preferred Stock and Class C Convertible
         Preferred Stock on any Redemption Date if the cost to the Corporation
         of such redemption would be greater than one-half of the Corporation's
         available average cash working capital balance for the quarter
         immediately preceding such Redemption Date. If a redemption is delayed
         pursuant to this Paragraph 7E, the Corporation shall redeem the shares
         to be so redeemed within 120 days of such Redemption Date.

                  8. Amendments. No provision of these terms of the Preferred
Stock may be amended, modified or waived without the written consent or
affirmative vote of the holders of at least two-thirds of the then outstanding
shares of Preferred Stock.

   121








               CLASS A PREFERRED STOCK AND CLASS B PREFERRED STOCK

         1. Number of Shares. There shall be two classes of Preferred Stock. The
Class A Convertible Preferred Stock shall consist of 1,562,500 shares, and the
Class B Convertible Preferred Stock shall consist of 2,151,420 shares. The Class
A Convertible Preferred Stock and the Class B Convertible Preferred Stock shall
sometimes be referred to herein collectively as the "Preferred Stock."

         2.       Voting.

                  2A. General. Except as may be otherwise provided in these
terms of the Preferred Stock or by law, the Preferred Stock shall vote together
with all other classes and class of stock of the Corporation as a single class
on all actions to be taken by the stockholders of the Corporation, including,
but not limited to actions amending the Certificate of Incorporation of the
Corporation to increase the number of authorized shares of Common Stock. Each
share of Preferred Stock shall entitle the holder thereof to such number of
votes per share on each such action as shall equal the number of shares of
Common Stock (including fractions of a share) into which each share of Preferred
Stock is then convertible.

                  2B. Board Size. The Corporation shall not, without the written
consent or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Class B Convertible Preferred Stock, given in writing or
by vote at a meeting, consenting or voting (as the case may be) separately as a
class, increase the maximum number of directors constituting the Board of
Directors to a number in excess of five.

                  2C. Board Seats. So long as the outstanding Class A
Convertible Preferred Stock represents at least 10% of the outstanding Common
Stock of the Corporation (assuming the conversion of all outstanding Preferred
Stock), the holders of the Class A Convertible Preferred Stock, voting as a
separate class, shall be entitled to elect one director of the Corporation. So
long as the outstanding Class B Convertible Preferred Stock represents at least
5% of the outstanding Common Stock of the Corporation (assuming the conversion
of all outstanding Preferred Stock), the holders of the Class B Convertible
Preferred Stock, voting as a separate class, shall be entitled to elect one
director of the Corporation (the "Class B Director"). The holders of the Common
Stock, voting as a separate class, shall be entitled to elect two directors of
the Corporation. A fifth director of the Corporation shall be such person, if
any, who has received a majority vote of the holders of the Class B Convertible
Preferred Stock, voting as a separate class, and a majority vote of the holders
of the Common Stock, voting as a separate class. At any meeting (or in a written
consent in lieu thereof) held for the purpose of electing directors, the
presence in person or by proxy (or the written consent) of the holders of a
majority of the shares of Class B Convertible Preferred Stock then outstanding
shall constitute a quorum of the Class B Convertible Preferred Stock for the
election of the director to be elected solely by the holders of the Class B
Convertible Preferred Stock or jointly by the holders of the Class B



   122




Convertible Preferred Stock and the Common Stock, and the
presence in person or by proxy (or the written consent) of the holders of a
majority of the shares of Class A Convertible Preferred Stock then outstanding
shall constitute a quorum of the Class A Convertible Preferred Stock for the
election of the director to be elected solely by the holders of the Class A
Convertible Preferred Stock. A vacancy in an directorship elected by the holders
of the Class A Convertible Preferred Stock or Class B Convertible Preferred
Stock shall be filled only by vote or written consent of the holders of the
Class A Convertible Preferred Stock or Class B Convertible Preferred Stock,
respectively; a vacancy in any directorship elected by the holders of the Common
Stock shall be filled only by vote or written consent of the holders of the
Common Stock; and a vacancy in the directorship elected jointly by the holders
of the Class B Convertible Preferred Stock and the Common Stock shall be filled
only by vote or written consent of the Class B Convertible Preferred Stock and
the Common Stock as provided above.

         3. Dividends. The holders of the Class A Convertible Preferred Stock
shall be entitled to receive, out of funds legally available therefor, (i) when
and if declared by at least four members of the Board of Directors, or (ii) upon
any liquidation, dissolution or winding up of the Corporation, quarterly
dividends at the rate per annum of $0.0224 per share (the "Class A Accruing
Dividends"). The holders of the Class B Convertible Preferred Stock shall be
entitled to receive, out of funds legally available therefor, (i) when and if
declared by at least four members of the Board of Directors, or (ii) upon any
liquidation, dissolution or winding up of the Corporation, quarterly dividends
at the rate per annum of $0.0532 per share (the "Class B Accruing Dividends").
The Class A Accruing Dividends and the Class B Accruing Dividends are sometimes
referred to herein collectively as the "Accruing Dividends." Accruing Dividends
shall accrue from day to day, whether or not earned or declared, and shall be
cumulative. No dividend shall be paid on the Preferred Stock, other than
Accruing Dividends, or on the Common Stock.

         4.       Liquidation.

                  4A. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Class B Convertible Preferred Stock shall first be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Class B Convertible Preferred Stock, to be paid an amount equal to $0.76 per
share plus, in the case of each share, an amount equal to all Class B Accruing
Dividends unpaid thereon (whether or not declared) and any other dividends
declared but unpaid thereon, computed to the date payment thereof is made
available, such amount payable with respect to one share of Class B Convertible
Preferred Stock being sometimes referred to as the "Class B Liquidation
Preference Payment" and with respect to all shares of Class B Convertible
Preferred Stock being sometimes referred to as the "Class B Liquidation
Preference Payments." If upon such liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the assets to be distributed
among the holders of Class B Convertible Preferred Stock shall be insufficient
to permit payment in full to the holders of Class B Convertible Preferred Stock
of the Class B Liquidation Preference Payments, then the entire assets of the
Corporation to be so distributed shall be distributed ratably among the holders
of Class B Convertible Preferred Stock.


   123




                  4B. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, after the holders of Class B
Convertible Preferred Stock shall have been paid in full the amounts to which
they shall be entitled pursuant to paragraph 4A, the holders of the shares of
Class A Convertible Preferred Stock shall then be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Class A Convertible Preferred Stock, to b paid an amount equal to $.32 per
share plus, in the case of each share, an amount equal to all Class A Accruing
Dividends unpaid thereon (whether or not declared) computed to the date payment
thereof is made available, such amount payable with respect to one share of
Class A Convertible Preferred Stock being sometimes referred to as the "Class A
Liquidation Preference Payment" and with respect to all shares of Class A
Convertible Preferred Stock being sometimes referred to as the "Class A
Liquidation Preference Payments." The Class A Liquidation Preference Payments
and the Class B Liquidation Preference Payments are sometimes referred to herein
collectively as the "Liquidation Preference Payments." If upon such liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed among the holders of Class A Convertible Preferred
Stock shall be insufficient to permit payment in full to the holders of Class A
Convertible Preferred Stock of the Class A Liquidation Preference Payments, then
the entire remaining assets of the Corporation to be so distributed shall be
distributed ratably among the holders of Class A Convertible Preferred Stock.

                  4C. Upon any such liquidation, dissolution or winding up of
the Corporation, immediately after the holders of Class B Convertible Preferred
Stock and Class A Convertible Preferred Stock shall have been paid in full their
respective Liquidation Preference Payments, the remaining net assets of the
Corporation available for distribution shall be distributed ratably among the
holders of Preferred Stock and Common Stock (with each share of Preferred Stock
being deemed, for such purpose, to b equal to the number of shares of Common
Stock (including fractions of a share) into which such share of Preferred Stock
is convertible immediately prior to the close of business on the business day
fixed for such distribution). The consolidation or merger of the Corporation
into or with any other entity or entities which results in the exchange of
outstanding shares of the Corporation for securities or other consideration
issued or paid or caused to be issued or paid by any such entity or affiliate
thereof (other than a merger to reincorporate the Corporation in a different
jurisdiction), and the sale, lease, abandonment, transfer or other disposition
by the Corporation of all or substantially all its assets (each such event a
"Liquidity Event"), shall be deemed to be a liquidation, dissolution or winding
up of the Corporation within the meaning of the provisions of this paragraph 4.

                  4D. Written notice of such liquidation, dissolution or winding
up, stating a payment date, the amount of the Liquidation Preference Payments
and the place where said Liquidation Preference Payments shall be payable, shall
be delivered in person, mailed by certified or registered mail, return receipt
requested, or sent by telecopier or telex, not less than 20 days prior to the
payment date stated therein, to the holders of record of Preferred Stock, such
notice to be addressed to each such holder at its address as shown by the
records of the Corporation. For purposes hereof, the Common Stock shall rank on
liquidation junior to the Class B Convertible Preferred Stock and Class A
Convertible Preferred Stock.




   124



         5. Restrictions. At any time when shares of Class B Convertible
Preferred Stock are outstanding, except where the vote or written consent of the
holders of a greater number of shares of the Corporation is required by law or
by the Certificate of Incorporation, and in addition to any other vote required
by law or the Certificate of Incorporation, without the approval of the holders
of at least two-thirds of the then outstanding shares of Class B Convertible
Preferred Stock, given in writing or by vote at a meeting, consenting or voting
(as the case may be) separately as a class, the Corporation will not:

                  5A. Create or authorize the creation of any additional class
or series of shares of stock unless the same ranks junior to the Class B
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, redemption and the payment of
dividends, or increase the authorized amount of the Class B Convertible
Preferred Stock or increase the authorized amount of any additional class or
series of shares of stock unless the same ranks junior to the Class B
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, redemption and the payment of
dividends, or create or authorize any obligation or security convertible into
shares of Class B Convertible Preferred Stock or into shares of any other class
or series of stock unless the same ranks junior to the Class B Convertible
Preferred Stock as to the distribution of assets on the liquidation, dissolution
or winding up of the Corporation, redemption and the payment of dividends,
whether any such creation, authorization or increase shall be by means of
amendment to the Certificate of Incorporation or by merger, consolidation or
otherwise; provided, that such consent shall not be unreasonably withheld for
the creation or issuance of an additional class or series of shares ranking
senior to the Class B Convertible Preferred Stock as to the distribution of
assets on the liquidation, dissolution or winding up of the Corporation
redemption and the payment of dividends (a "Senior Security"), but provided
further, that if, within a reasonable time of the submission of a proposal for
the issuance of a Senior Security, information comes to light indicating that
such consent was withheld solely or primarily for the purpose of negotiating the
price of an additional investment by the holders of the Class B Convertible
Preferred Stock, then such consent shall be deemed to have been unreasonably
withheld for purposes of this subparagraph 5A.

                  5B. Consent to any liquidation, dissolution or winding up of
the Corporation or consolidate or merge into or with any other entity or
entities or sell, lease, abandon, transfer or otherwise dispose of all or
substantially all its assets, unless such action would result in an annualized
return to the holders of the Class B Convertible Preferred Stock of at least
30%;
                  
                  5C. Amend, alter or repeal its Certificate of Incorporation or
By-Laws if the effect would be materially detrimental or adverse in any manner
with respect to the rights of the holders of the Class B Convertible Preferred
Stock;

                  5D. Purchase or set aside any sums for the purchase of, or pay
any dividend or make any distribution on, any shares of stock other than the
Class B Convertible Preferred Stock, except for (i) Class A Accruing Dividends,
(ii) dividends or other distributions payable on the Common Stock solely in the
form of additional shares of Common Stock, and (iii) the purchase 


   125



of shares of Common Stock from former employees of the Corporation who acquired
such shares directly from the Corporation if each such purchase is made pursuant
to contractual rights held by the Corporation relating to the termination of
employment of such former employee and the purchase price (except in the case of
agreements executed prior to July 12, 1996) does not exceed the original issue
price paid by such former employee to the Corporation for such shares; or

                  5E. Redeem or otherwise acquire any shares of Class B
Convertible Preferred Stock except as expressly authorized in paragraph 7 hereof
or pursuant to a purchase offer made pro rata to all holders of the shares of
Class B Convertible Preferred Stock on the basis of the aggregate number of
outstanding shares of Class B Convertible Preferred Stock then held by each such
holder.

         6. Conversions. The holders of shares of Preferred Stock shall have the
following conversion rights:

                  6A. Right to Convert. Subject to the terms and conditions of
this paragraph 6, the holder of any share or shares of Preferred Stock shall
have the right, at its option at any time, to convert any such shares of
Preferred Stock into such number of fully paid and nonassessable shares of
Common Stock as is obtained by (i) multiplying the number of shares of Preferred
Stock so to be converted by the Original Purchase Price of such share (which
shall be $0.32 in the case of the Class A Convertible Preferred Stock and $.76
in the case of Class B Convertible Preferred Stock) and (ii) dividing the result
by the conversion price of the Original Purchase Price of such share or, in case
an adjustment of such price has taken place pursuant to the further provisions
of this paragraph 6, then by the conversion price as last adjusted and in effect
at the date any share or shares of Preferred Stock are surrendered for
conversion (such price, or such price as last adjusted, being referred to as the
"Conversion Price" and, with respect to the Class B Convertible Preferred Stock,
the "Class B Conversion Price"). Such rights of conversion shall be exercised by
the holder thereof by giving written notice that the holder elects to convert a
stated number of shares of Preferred Stock into Common Stock and by surrender of
a certificate or certificates for the shares so to be converted to the
Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holders
of the Preferred Stock) at any time during its usual business hours on the date
set forth in such notice, together with a statement of the name or names (with
address) in which the certificate or certificates for shares of Common Stock
shall be issued.

                  6B. Issuance of Certificates; Time Conversion Effected.
Promptly after the receipt of the written notice referred to in subparagraph 6A
and surrender of the certificate or certificates for the share or shares of
Preferred Stock to be converted, the Corporation shall issue and deliver, or
cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, a certificate or certificates for the number of
whole shares of Common Stock issuable upon the conversion of such share or
shares of Preferred Stock. To the extent permitted by law, such conversion shall
be deemed to have been effected and the Conversion Price shall be determined as
of the close of business on the date on which such written notice shall have
been received by the Corporation and the certificate or certificates for such
share or shares shall have been surrendered as aforesaid, and at such time the
rights of the holder of such 



   126



share or shares of Preferred Stock shall cease, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.

                  6C. Fractional Shares; Dividends; Partial Conversion. No
fractional shares shall be issued upon conversion of Preferred Stock into Common
Stock and no payment or adjustment shall be made upon any conversion on account
of any cash dividends on the Common Stock issued upon such conversion. At the
time of each conversion, the Corporation shall pay in cash an amount equal to
all dividends, excluding Accruing Dividends, accrued and unpaid on the shares of
Preferred Stock surrendered fo conversion to the date upon which such conversion
is deemed to take place as provided in subparagraph 6B. In case the number of
shares of Preferred Stock represented by the certificate or certificates
surrendered pursuant to subparagraph 6A exceeds the number of shares converted,
the Corporation shall, upon such conversion, execute and deliver to the holder,
at the expense of the Corporation, a new certificate or certificates for the
number of shares of Preferred Stock represented by the certificate or
certificates surrendered which are not to be converted. If any fractional share
of Common Stock would, except for the provisions of the first sentence of this
subparagraph 6C, be delivered upon such conversion, the Corporation, in lieu of
delivering such fractional share, shall pay to the holder surrendering the
Preferred Stock for conversion an amount in cash equal to the current market
price of such fractional share as determined in good faith by the Board of
Directors of the Corporation.

                  6D. Adjustment of Price Upon Issuance of Common Stock. Except
as provided in subparagraph 6E, if and whenever the Corporation shall issue or
sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to
have issued or sold, any shares of Common Stock for a consideration per share
less than the Class B Conversion Price in effect immediately prior to the time
of such issue or sale, then, forthwith upon such issue or sale, the Class B
Conversion Price shall be reduced t the price determined by dividing (i) an
amount equal to the sum of (a) the number of shares of Common Stock outstanding
immediately prior to such issue or sale multiplied by the then existing Class B
Conversion Price and (b) the consideration, if any, received by the Corporation
upon such issue or sale, by (ii) the total number of shares of Common Stock
outstanding immediately after such issue or sale.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                  6D(1) Issuance of Rights or Options. In case at any time the
         Corporation shall in any manner grant (whether directly or by
         assumption in a merger or otherwise) any warrants or other rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or security convertible into or exchangeable
         for Common Stock (such warrants, rights or options being called
         "Options" and such convertible or exchangeable stock or securities
         being called "Convertible Securities") whether or not such Options or
         the right to convert or exchange any such Convertible Securities are
         immediately exercisable, and the price per share for which Common Stock
         is issuable upon the exercise of such Options or upon the conversion or
         exchange of such Convertible Securities (determined by dividing (i) the
         total amount, if any, received or 



   127



         receivable by the Corporation as consideration for the granting of such
         Options, plus the minimum aggregate amount of additional consideration
         payable to the Corporation upon the exercise of all such Options, plus,
         in the case of such Options which relate to Convertible Securities, the
         minimum aggregate amount of additional consideration, if any, payable
         upon the issue or sale of such Convertible Securities and upon the
         conversion or exchange thereof, by (ii) the total maximum number of
         shares of Common Stock issuable upon the exercise of such Options or
         upon the conversion or exchange of all such Convertible Securities
         issuable upon the exercise of such Options) shall be less than the
         Class B Conversion Price in effect immediately prior to the time of the
         granting of such Options, then the total maximum number of shares of
         Common Stock issuable upon the exercise of such Options or upon
         conversion or exchange of the total maximum amount of such Convertible
         Securities issuable upon the exercise of such Options shall be deemed
         to have been issued for such price per share as of the date of granting
         of such Options or the issuance of such Convertible Securities and
         thereafter shall be deemed to be outstanding. Except as otherwise
         provided in subparagraph 6D(3), no adjustment of the Class B Conversion
         Price shall be made upon the actual issue of such Common Stock or of
         such Convertible Securities upon exercise of such Options or upon the
         actual issue of such Common Stock upon conversion or exchange of such
         Convertible Securities.

                  6D(2) Issuance of Convertible Securities. In case the
         Corporation shall in any manner issue (whether directly or by
         assumption in a merger or otherwise) or sell any Convertible
         Securities, whether or not the rights to exchange or convert any such
         Convertible Securities are immediately exercisable, and the price per
         share for which Common Stock is issuable upon such conversion or
         exchange (determined by dividing (i) the total amount received or
         receivable by the Corporation as consideration for the issue or sale of
         such Convertible Securities, plus the minimum aggregate amount of
         additional consideration, if any, payable to the Corporation upon the
         conversion or exchange thereof, by (ii) the total maximum number of
         shares of Common Stock issuable upon the conversion or exchange of all
         such Convertible Securities) shall be less than the Class B Conversion
         Price in effect immediately prior to the time of such issue or sale,
         then the total maximum number of shares of Common Stock issuable upon
         conversion or exchange of all such Convertible Securities shall be
         deemed to have been issued for such price per share as of the date of
         the issue or sale of such Convertible Securities and thereafter shall
         be deemed to be outstanding, provided that (a) except as otherwise
         provided in subparagraph 6D(3), no adjustment of the Class B Conversion
         Price shall be made upon the actual issue of such Common Stock upon
         conversion or exchange of such Convertible Securities and (b if any
         such issue or sale of such Convertible Securities is made upon exercise
         of any Options to purchase any such Convertible Securities for which
         adjustments of the Class B Conversion Price have been or are to be made
         pursuant to other provisions of this subparagraph 6D, no further
         adjustment of the Class B Conversion Price shall be made by reason of
         such issue or sale.

                  6D(3) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any Option referred to in subparagraph 6D(1), the
         additional consideration, if any, payable upon the conversion 




   128



         or exchange of any Convertible Securities referred to in subparagraph
         6D(1) or 6D(2), or the rate at which Convertible Securities referred to
         in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for
         Common Stock shall change at any time (including, but not limited to,
         changes under or by reason of provisions designed to protect against
         dilution), the Class B Conversion Price in effect at the time of such
         event shall forthwith be readjusted to the Class B Conversion Price
         which would have been in effect at such time had such Options or
         Convertible Securities still outstanding provided for such changed
         purchase price, additional consideration or conversion rate, as the
         case may be, at the time initially granted, issued or sold, but only if
         as a result of such adjustment the Class B Conversion Price then in
         effect hereunder is thereby reduced; and on the termination of any such
         Option or any such right to convert or exchange such Convertible
         Securities, the Class B Conversion Price then in effect hereunder shall
         forthwith be increased to the Class B Conversion Price which would have
         been in effect at the time of such termination had such Option or
         Convertible Securities, to the extent outstanding immediately prior to
         such termination, never been issued.

                  6D(4) Stock Dividends. In case the Corporation shall declare a
         dividend or make any other distribution upon any stock of the
         Corporation (other than the Common Stock) payable in Common Stock,
         Options or Convertible Securities, then any Common Stock, Options or
         Convertible Securities, as the case may be, issuable in payment of such
         dividend or distribution shall be deemed to have been issued or sold
         without consideration.


                  6D(5) Consideration for Stock. In case any shares of Common
         Stock, Options or Convertible Securities shall be issued or sold for
         cash, the consideration received therefor shall be deemed to be the
         amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any shares of Common Stock, Options or Convertible Securities
         shall be issued o sold for a consideration other than cash, the amount
         of the consideration other than cash received by the Corporation shall
         be deemed to be the fair value of such consideration as determined in
         good faith by the Board of Directors of the Corporation, without
         deduction of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any Options shall be issued in connection with the issue and
         sale of other securities of th Corporation, together comprising one
         integral transaction in which no specific consideration is allocated to
         such Options by the parties thereto, such Options shall be deemed to
         have been issued for such consideration as determined in good faith by
         the Board of Directors of the Corporation.

                  6D(6) Record Date. In case the Corporation shall take a record
         of the holders of its Common Stock for the purpose of entitling them
         (i) to receive a dividend or other distribution payable in Common
         Stock, Options or Convertible Securities or (ii) to subscribe for or
         purchase Common Stock, Options or Convertible Securities, then such
         record date shall be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the 


   129



         making of such other distribution or the date of the granting of such
         right of subscription or purchase, as the case may be.

                  6D(7) Treasury Shares. The number of shares of Common Stock
         outstanding at any given time shall not include shares owned or held by
         or for the account of the Corporation, and the disposition of any such
         shares shall be considered an issue or sale of Common Stock for the
         purpose of this subparagraph 6D.


                  6E. Certain Issues of Common Stock Excepted. Anything herein
to the contrary notwithstanding, the Corporation shall not be required to make
any adjustment of the Class B Conversion Price in the case of the issuance from
and after the date of filing of these terms of the Preferred Stock of up to an
aggregate of 925,000 shares (appropriately adjusted to reflect the occurrence of
any event described in subparagraphs 6E or 6F) (the "Reserved Shares") of Common
Stock to directors, officers, employees or consultants of the Corporation in
connection with their service as directors of the Corporation, their employment
by the Corporation or their retention as consultants by the Corporation
(provided that the number of Reserved Shares may be increased (a) prior to July
12, 1997, with the approval of a majority of the Board of Directors including
the Class B Director and (b) after July 12, 1997, with the approval of either
(i) a majority of the Board of Directors including the Class B Director or (ii)
all directors other than the Class B Director), plus such number of shares of
Common Stock which are repurchased by the Corporation from such persons after
such date pursuant to contractual rights held by the Corporation and at
repurchase prices not exceeding the respective original purchase prices paid by
such persons to the Corporation therefor.

                  6F. Subdivision or Combination of Common Stock. In case the
Corporation shall at any time subdivide (by any stock split, stock dividend or
otherwise) its outstanding shares of Common Stock into a greater number of
shares, the Conversion Price in effect immediately prior to such subdivision
shall be proportionately reduced, and, conversely, in case the outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be
proportionately increased. In the case of any such subdivision, no further
adjustment shall be made pursuant to subparagraph 6D(4) by reason thereof.

                  6G. Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provisions shall be made whereby each holder of a share or shares
of Preferred Stock shall thereupon hav the right to receive, upon the basis and
upon the terms and conditions specified herein and in lieu of the shares of
Common Stock immediately theretofore receivable upon the conversion of such
share or shares of Preferred Stock, such shares of stock, securities or assets
as may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
Common Stock immediately theretofore receivable upon such conversion had such
reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with 



   130



respect to the rights and interests of such holder to the end that the
provisions hereof (including without limitation provisions for adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights.

                  6H. Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by delivery in person, certified or registered mail, return
receipt requested, telecopier or telex, addressed to each holder of shares of
Preferred Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the Conversion Price resulting from such
adjustment, setting forth in reasonable detai the method upon which such
calculation is based.

                  6I.      Other Notices.  In case at any time:   

                  (1) the Corporation shall declare any dividend upon its Common
Stock payable in cash or stock or make any other distribution to the holders of
its Common Stock;

                  (2) the Corporation shall offer for subscription pro rata to
the holders of its Common Stock any additional shares of stock of any class or
other rights; 

                  (3) there shall be any capital reorganization or
reclassification of the capital stock of the Corporation, or a consolidation or
merger of the Corporation with or into another entity or entities, or a sale,
lease, abandonment, transfer or other disposition of all or substantially all
its assets; or

                  (4) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by delivery
in person, certified or registered mail, return receipt requested, telecopier or
telex, addressed to each holder of any shares of Preferred Stock at the address
of such holder as shown on the books of the Corporation, (a) at least 20 days'
prior written notice of the date on which the books of the Corporation shall
close or a record shall be taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, disposition, dissolution, liquidation or winding up, at
least 20 days' prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause (a) shall also specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto and such notice in
accordance with the foregoing clause (b) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding up, as the case may be.



   131




                  6J. Stock to be Reserved. The Corporation will at all times
reserve and keep available out of its authorized Common Stock, solely for the
purpose of issuance upon the conversion of Preferred Stock as herein provided,
such number of shares of Common Stock as shall then be issuable upon the
conversion of all outstanding shares of Preferred Stock. The Corporation
covenants that all shares of Common Stock which shall be so issued shall be duly
and validly issued and fully paid and nonassessable and free from all taxes,
liens and charges with respect to the issue thereof, and, without limiting the
generality of the foregoing, the Corporation covenants that it will from time to
time take all such action as may be requisite to assure that the par value per
share of the Common Stock is at all times equal to or less than the Conversion
Price in effect at the time. The Corporation will take all such action as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Preferred Stock would exceed
the total number of shares of Common Stock then authorized by the Certificate of
Incorporation.

                  6K. No Reissuance of Preferred Stock. Shares of Preferred
Stock which are converted into shares of Common Stock as provided herein shall
not be reissued.

                  6L. Issue Tax. The issuance of certificates for shares of
Common Stock upon conversion of Preferred Stock shall be made without charge to
the holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder of the Preferred Stock which is being
converted.

                  6M. Closing of Books. The Corporation will at no time close
its transfer books against the transfer of any Preferred Stock or of any shares
of Common Stock issued or issuable upon the conversion of any shares of
Preferred Stock in any manner which interferes with the timely conversion of
such Preferred Stock, except as may otherwise be required to comply with
applicable securities laws.


                  6N. Definition of Common Stock. As used in this paragraph 6,
the term "Common Stock" shall mean and include the Corporation's authorized
Common Stock, par value $.001 per share, as constituted on the date of filing of
these terms of the Preferred Stock, and shall also include any capital stock of
any class of the Corporation thereafter authorized which shall not be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends or in the distribution of assets upon the voluntary or
involuntary liquidation, dissolution or winding up of the Corporation; provided
that the shares of Common Stock receivable upon conversion of shares of
Preferred Stock shall include only shares designated as Common Stock of the
Corporation on the date of filing of this instrument, or in case of any
reorganization or reclassification of the outstanding shares thereof, the stock,
securities or assets provided for in subparagraph 6G.


   132




                  6O. Mandatory Conversion. If at any time (i) the Corporation
shall effect a firm commitment underwritten public offering of shares of Common
Stock in which (A) the aggregate price paid for such shares by the public shall
be at least $15,000,000 and (B) the price paid by the public for such shares
shall be at least $3.80 per share (appropriately adjusted to reflect the
occurrence of any event described in subparagraph 6F), or (ii) a Liquidity Event
shall occur in which (a) the holders o shares of any class of Preferred Stock
would receive consideration for all of such shares (as if converted to Common
Stock) of at least four (4) times the original purchase price of such shares
(for example, at least $3.04 for (i) each share of Class B Convertible Preferred
Stock or (ii) all shares of Common Stock into which such share of Class B
Convertible Preferred Stock is convertible), then effective upon the closing of
the sale of such shares by the Corporation pursuant to such public offering or
immediately prior to the occurrence of such Liquidity Event, as the case may be,
all outstanding shares of Preferred Stock (in the case of a public offering) or
such class of Preferred Stock (in the case of a Liquidity Event) shall
automatically convert to shares of Common Stock on the basis set forth in this
paragraph 6. Holders of shares of Preferred Stock so converted may deliver to
the Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to such
holders) during its usual business hours, the certificate or certificates for
the shares so converted. As promptly as practicable thereafter, the Corporation
shall issue and deliver to such holder a certificate or certificates for the
number of whole shares of Common Stock to which such holder is entitled,
together with any cash dividends and payment in lieu of fractional shares to
which such holder may be entitled pursuant to subparagraph 6C. Until such time
as a holder of shares of Preferred Stock shall surrender his or its certificates
therefor as provided above, such certificates shall be deemed to represent the
shares of Common Stock to which such holder shall be entitled upon the surrender
thereof.

         7. Redemption. The shares of Class B Convertible Preferred Stock shall
be redeemed as follows:

                  7A. Mandatory Redemption. On June 30, 2001, and on each of the
next two anniversaries thereafter (the "Redemption Dates," and each a
"Redemption Date"), the Corporation shall redeem any outstanding shares of Class
B Convertible Preferred Stock according to the percentages listed below:


                                                  Percentage of Shares of 
                                                  Class B Convertible     
                                                  Preferred Stock then    
Date of Redemption                                Outstanding to be Redeemed 

June 30, 2001                                     33-1/3% of all the shares of 
                                                  Class B Convertible Preferred 
                                                  Stock Outstanding on June 30,
                                                  2001   

June 30, 2002                                     50% of all the shares of Class
                                                  B Convertible Preferred Stock
                                                  outstanding on June 30, 2002



   133



June 30, 2003                                     100% of all the shares of 
                                                  Class B Convertible Preferred
                                                  Stock outstanding on June 30,
                                                  2003

                  7B.      Redemption Price and Payment.  The shares of Class B 
Convertible Preferred Stock to be redeemed on any Redemption Date shall be
redeemed by paying for each share in cash an amount equal to $0.76 per share
plus, in the case of each share, an amount equal to all dividends, excluding
Accruing Dividends, declared but unpaid thereon, computed to such Redemption
Date, such amount being referred to as the "Redemption Price". Such payment
shall be made in full on the applicable Redemption Date to the holders entitled
thereto.

                  7C.      Redemption Mechanics. At least 20 but not more than
30 days prior to each Redemption Date, written notice (the "Redemption Notice")
shall be given by the Corporation by delivery in person, certified or registered
mail, return receipt requested, telecopier or telex, to each holder of record
(at the close of business on the business day next preceding the day on which
the Redemption Notice is given) of shares of Class B Convertible Preferred Stock
notifying such holder of the redemption and specifying the Redemption Price,
such Redemption Date, the number of shares of Class B Convertible Preferred
Stock to be redeemed from such holder (computed on a pro rata basis in
accordance with the number of such shares held by all holders thereof) and the
place where said Redemption Price shall be payable. The Redemption Notice shall
be addressed to each holder at his address as shown by the records of the
Corporation. From and after the close of business on a Redemption Date, unless
there shall have been a default in the payment of the Redemption Price, all
rights of holders of shares of Class B Convertible Preferred Stock (except the
right to receive the Redemption Price) shall cease with respect to the shares to
be redeemed on such Redemption Date, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever. If the funds of the Corporation legally available for
redemption of shares of Class B Convertible Preferred Stock on a Redemption Date
are insufficient to redeem the total number of shares of Class B Convertible
Preferred Stock to be redeemed on such Redemption Date, the holders of such
shares shall share ratably in any funds legally available for redemption of such
shares according to the respective amounts which would be payable to them if the
full number of shares to be redeemed on such Redemption Date were actually
redeemed. The shares of Class B Convertible Preferred Stock required t be
redeemed but not so redeemed shall remain outstanding and entitled to all rights
and preferences provided herein. At any time thereafter when additional funds of
the Corporation are legally available for the redemption of such shares of Class
B Convertible Preferred Stock, such funds will be used, at the end of the next
succeeding fiscal quarter, to redeem the balance of such shares, or such portion
thereof for which funds are then legally available, on the basis set forth
above.

                  7D.      Redeemed or Otherwise Acquired Shares to be Retired. 
Any shares of Class B Convertible Preferred Stock redeemed pursuant to this
paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever
shall be canceled and shall not under any circumstances be reissued; and the
Corporation may from time to time take such appropriate corporate action as may
be necessary to reduce accordingly the number of authorized shares of Class B
Convertible Preferred Stock.





                  7E.      Delay of Redemption. Notwithstanding paragraph 7A 
hereof, the Corporation shall not be required to redeem any shares of Class B
Convertible Preferred Stock on any Redemption Date if the cost to the
Corporation of such redemption would be greater than one-half of the
Corporation's available average cash working capital balance for the quarter
immediately preceding such Redemption Date. If a redemption is delayed pursuant
to this Paragraph 7E, the Corporation shall redeem the shares to be so redeemed
within 120 days of such Redemption Date.

         8.       Amendments.  No provision of these terms of the Preferred 
Stock may be amended, modified or waived without the written consent or
affirmative vote of the holders of at least two-thirds of the then outstanding
shares of Preferred Stock.
