appraisal to be borne by the Company.

         C. "Conversion Date" means, for any Optional Conversion, the date
specified in the notice of conversion substantially in the form of EXHIBIT A

Conversion is faxed (or delivered by other means) to the Company before 11:59

has not received at least $3.0 million in investments from a "strategic
investor" group; (ii) on March 31, 2001, the Company has less than $6.0 million

and (y) on every three-month anniversary thereafter (each a "Reset Date"), the
Conversion Price then in effect shall be reset, if lower, to the greater of (x)
the Market Price (as defined below) calculated on such Reset Date and (y) the
Floor Price (as defined below). The Conversion Price shall also be subject to
adjustment for any stock splits, combinations, stock dividends,
reclassifications or other events as provided in Article XI hereof and as
otherwise provided in this Certificate of Designation. For purposes of
clarification, a "month anniversary" shall mean, in cases where there is no
exact anniversary date, the final day of the month in question; for example, the
three-month anniversary of November 30, 2001 shall be February 28, 2002.

         E. "Floor Price" means One Dollar and Thirty Seven and One-Half Cents
($1.375); provided, however, that if an Adjustment has occurred which reduces
the Conversion Price, the Floor Price shall be reduced by ten percent (10%) for
each such Adjustment. The Floor Price shall be subject to equitable adjustment
for any stock splits, combinations, stock dividends, reclassifications or
similar events.

         F. "Liquidity Conditions" means that (A) all shares of the Company's
common stock, $0.001 par value per share ("Common Stock") issuable upon

then authorized and reserved for issuance, (ii) have been registered for resale
in an appropriate and effective registration statement under the Securities Act

are listed for trading on any of the Nasdaq National Market, the Nasdaq SmallCap
Market, the New York Stock Exchange or the American Stock Exchange; (B) there

<PAGE>   4

         G. "Market Price" means, as of any date, the average of the five (5)
lowest Volume Weighted Average Prices ("VWAPs"), as reported by Bloomberg for
the fifteen (15) consecutive trading days immediately preceding, but not
including, such determination date.

         H. "Premium" with respect to each share of Preferred Stock means 2,750
x (N/365) x (.06), where

            N=    the number of days from the most recent Premium Payment Date
                  (as defined below) on which Premium has been paid, or if no
                  Premium Payment Date has occurred, the day after the original
                  issuance date of the share of Preferred Stock, to and
                  including the date of determination.

Premium is payable semi-annually on the last business day of each June and
December (each, a "Premium Payment Date") with respect to each share of
Preferred Stock then outstanding and shall be paid, at the option of the
Company, (i) in cash or (ii) if and so long as the Liquidity Conditions are
satisfied as of the last business day of such quarter, in additional shares of
Preferred Stock of Face Amount equal to the Premium.

         I. "Securities Purchase Agreements" means the Securities Purchase
Agreements dated February 2, 2001 by and between the Company and the purchasers
of Preferred Stock and Warrants thereunder.

                                 IV. CONVERSION

         A. Conversion at the Option of the Holder. Subject to the limitations
on conversions contained in Section IV.G, each Holder may, at any time
immediately following the First Closing (as defined in the Securities Purchase
Agreements) and from time to time thereafter convert (an "Optional Conversion")
any or all of its shares of Preferred Stock into a number of fully paid and
non-assessable shares of Common Stock determined, for each share of Preferred
Stock so to be converted, in accordance with the following formula:

                      (Accrued but unpaid Premium + $2,750)
                      -------------------------------------
                                Conversion Price

         Notwithstanding the foregoing, if on the Conversion Date, the Liquidity
Conditions are not satisfied, then (x) the number of shares of Common Stock into
which each share of Preferred Stock shall be converted shall instead be equal to
$2,750/Conversion Price and (y) the Company shall pay the converting Holder an
amount in cash equal to the accrued but unpaid Premium on each share of
Preferred Stock so converted.

         B. Mechanics of Conversion. In order to effect an Optional Conversion,
a Holder shall fax (or otherwise deliver) a copy of the fully executed Notice of
Conversion to the Company. Upon receipt by the Company of the fax copy of a
Notice of Conversion from a Holder, the Company shall immediately send, via fax,
a confirmation to such Holder stating that

                                      -4-
<PAGE>   5

the Notice of Conversion has been received, the date upon which the Company
expects to deliver the Common Stock issuable upon such conversion and the name
and telephone number of a contact person at the Company regarding the
conversion. Promptly after receipt of such confirmation of receipt of Notice of
Conversion the Holder shall surrender or cause to be surrendered personally or
via a reputable overnight courier for next business day delivery to the Company
the certificates representing the Preferred Stock being converted (the
"Preferred Stock Certificates") accompanied by duly executed stock powers and a
copy of the Notice of Conversion (or, in lieu thereof, materials contemplated by
Section XIV.B., if applicable).

         C. Delivery of Common Stock Upon Conversion. Subject to Section IV. F
hereof, upon the delivery of a Notice of Conversion, the Company shall as soon
as practicable, but in no event later than the later of (a) the third (3rd)
business day following the Conversion Date and (b) the day that is the first
business day following the date of surrender of the Preferred Stock Certificates
(or satisfaction of the provisions of Section XIV.B, if applicable) (the
"Delivery Period"), deliver to the Holder (or at its direction) (x) that number
of shares of Common Stock issuable upon conversion of such shares of Preferred
Stock being converted and (y) a certificate representing the number of shares of
Preferred Stock not being converted, if any. Delivery under this Section IV. C.
as to shares of Common Stock being so delivered shall be made by electronically
transmitting the Common Stock issuable upon conversion to the Holder by
crediting the account of Holder's prime broker with DTC through its Deposit
Withdrawal Agent Commission ("DWAC") system or other electronic delivery system
selected by Holder, or, if the Holder so requests as to such Common Stock and as
to the certificate with respect to Preferred Stock pursuant to clause (y) above,
such delivery shall be made personally or by reputable overnight courier. The
person or persons entitled to receive shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder of such shares
at the beginning of business on the Conversion Date and such shares shall be
issued and outstanding as of such date.

         D. Taxes. The Company shall pay any and all taxes (other than transfer
taxes or income taxes, if any, payable by the Purchaser) which may be imposed
with respect to the issuance and delivery of the shares of Common Stock pursuant
to conversion of the Preferred Stock.

         E. No Fractional Shares. No fractional shares of Common Stock are to be
issued upon the conversion of Preferred Stock, but the Company shall instead pay
a cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Market Price of a share
of Common Stock on the date of such conversion.

         F. Conversion Disputes. In the case of any dispute with respect to a
conversion, the Company shall promptly issue such number of shares of Common
Stock as are not disputed in accordance with Sections IV.A and IV.C hereof. If
such dispute involves the calculation of the Conversion Price, the Company shall
submit the disputed calculations to an independent accounting firm of national
standing, acceptable to Holder, via facsimile within two (2) business days of
receipt of the Notice of Conversion. The accounting firm shall audit the
calculations and notify the Company and the Holder of the results no later than
two (2) business days from the date it receives the disputed calculations. The
accounting firm's calculation shall be deemed conclusive, absent manifest error.
As soon as possible thereafter, the Company shall then issue

                                      -5-
<PAGE>   6

the appropriate number of shares of Common Stock in accordance with Sections
IV.A and IV.C hereof.

         G. Limitation on Conversions. The conversion of shares of Preferred
Stock shall be subject to the following limitations (each of which limitations
shall be applied independently):

               (i) Cap Amount. Prior to Stockholder Approval and regardless of
whether shares of the Company's Common Stock are listed for trading on the
Nasdaq National Market, the Nasdaq SmallCap Market or the OTC Bulletin Board, in
no event shall the total number of shares of Common Stock issued upon conversion
of the Preferred Stock and exercise of the Warrants (if required) exceed the
maximum number of shares of Common Stock that the Company can issue without
stockholder approval pursuant to Nasdaq Rule 4350 (or any successor rule) (the
"Cap Amount") which, as of the date of initial issuance of shares of Preferred
Stock and the Warrants, shall be 19.99% of the total number of shares of Common
Stock outstanding immediately prior to the First Closing (or any such higher
number as the rules permit). A portion of the Cap Amount shall be applicable to
a Holder as provided in Section XIV.C. The foregoing restriction shall not apply
to the extent waived, modified or otherwise permitted by the Nasdaq National
Market System or the Nasdaq SmallCap Market, as applicable to the Common Stock.

               (ii) Five Percent Holdings. Notwithstanding anything to the
contrary contained herein, the Preferred Stock shall not be convertible by a
Holder to the extent (but only to the extent) that, if convertible by such
Holder, such Holder would beneficially own in excess of 4.9% of the shares of
Common Stock. To the extent the foregoing limitation applies, the determination
of whether Preferred Stock shall be convertible (vis-a-vis other convertible,
exercisable or exchangeable securities owned by such Holder) and of which
Preferred Stock shall be convertible (as among shares of Preferred Stock) shall,
subject to such aggregate percentage limitation, be determined on the basis of
first submission to the Company for conversion or exercise or exchange, as the
case may be. No prior inability to convert Preferred Stock pursuant to this
Section shall have any effect on the applicability of the provisions of this
Section with respect to any subsequent determination of convertibility. For the
purposes of this Section, beneficial ownership and all determinations and
calculations, including without limitation, with respect to calculations of
percentage ownership, shall be made in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and Regulation 13D and G
thereunder. The provisions of this Section shall be implemented in a manner
otherwise than in strict conformity with the terms of this Section: (i) to
correct this subsection (or any portion thereof) which may be defective or
inconsistent with the intended 4.9% beneficial ownership limitation herein
contained or to make changes or supplements necessary or desirable to properly
give effect to such 4.9% limitation; and (ii) with respect to any other matter,
with the consent of the holders of majority of the then outstanding shares of
Common Stock. The limitations contained in this Section shall apply to a
successor Holder of Preferred Stock.

         H. Required Conversion at Maturity. Subject to the limitations set
forth in Section IV.G. and provided the Liquidity Conditions are satisfied, each
share of Preferred Stock outstanding on the third (3rd) anniversary of the First
Closing (the "Maturity Date") (and any accrued and unpaid Conversion Default
Payments (as defined herein)), automatically shall be converted into shares of
Common Stock on such date in accordance with the conversion formula

                                      -6-
<PAGE>   7

set forth in Section IV.A (the "Required Conversion at Maturity"). If a Required
Conversion at Maturity occurs, the Company and the Holders shall follow the
applicable conversion procedures set forth in this Article IV; provided,
however, that a Notice of Conversion shall be deemed to be delivered to the
Company on the Maturity Date.

         I. Optional Company Conversion. So long as the Common Stock underlying
the Preferred Stock is then registered pursuant to an effective registration
statement, upon the earlier of: (i) the business day immediately following the
final day of the first period of twenty (20) consecutive trading days beginning
after the first anniversary of the First Closing during which the Closing Bid
Price for the Company's Common Stock is greater than $5.50 per share (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) on each such trading date or (ii) the closing of an underwritten public
offering of the Company's Common Stock at a public offering price (prior to
underwriters' discounts and expenses) equal to or exceeding $5.50 per share of
Common Stock (as adjusted for any stock dividends, combinations or splits with
respect to such shares) resulting in gross proceeds of at least $30 million
(each a "Optional Conversion Trigger Event"), the Company shall have the option
upon twenty (20) business days written notice to the Holders to convert the
outstanding shares of Preferred Stock into Common Stock at the then effective
Conversion Price.

              V. RESERVATION OF AUTHORIZED SHARES OF COMMON STOCK

         The Company shall initially have authorized and reserved and keep
available for issuance not less than 19,879,334 shares of Common Stock (such
number to be subject to equitable adjustment for any stock splits, stock
dividends, reclassification or similar events) (the "Reserved Amount") solely
for the purpose of effecting the conversion of the Preferred Stock and the
exercise of the Warrants issued pursuant to the Securities Purchase Agreements
without giving effect to any limitations on the conversion thereof. Without
limiting the foregoing, the Company shall increase the Reserved Amount so that
at all times there are reserved and kept available out of its authorized but
unissued shares of Common Stock a sufficient number of shares of Common Stock to
provide for the full conversion of all outstanding Preferred Stock and exercise
of the Warrants and issuance of the shares of Common Stock in connection
therewith, without giving effect to any limitations on the conversion or
exercise thereof. A portion of the Reserved Amount shall be allocated to a
Holder as provided in Section XIV.C.

                  VI. COMPLIANCE WITH CAP AMOUNT RESTRICTIONS

         Share Authorization. The Company shall, in the Proxy Statement
circulated by the Company in connection with the Company's next annual meeting
of stockholders, but in no event later than May 31, 2001, solicit by proxy the
authorization (the "Stockholder Approval") (a) by the required vote under Nasdaq
Rule 4350 of the stockholders of the Company of (i) the issuance of shares of
Common Stock upon conversion of shares of Preferred Stock pursuant to the terms
hereof and the exercise of the Warrants pursuant to the terms thereof in the
aggregate in excess of 19.99% of the outstanding shares of Common Stock, and
(ii) the issuance of Preferred Stock and warrants with an aggregate purchase
price of at least $745,000 to certain officers of the Company, and (b) if
necessary and to the extent effected by stockholder vote, to

                                      -7-
<PAGE>   8

eliminate any prohibitions (including pursuant to Nasdaq Rule 4350) under the
rules or regulations of any stock exchange, interdealer quotation system or
other self-regulatory organization with jurisdiction over the Company or any of
its securities on the Company's ability to issue shares of Common Stock in
excess of the Cap Amount. The Company shall use its best efforts to obtain the
Stockholder Approval no later than May 31, 2000.

                      VII. FAILURE TO SATISFY CONVERSIONS

         A. Conversion Default Payments. If, at any time, (x) a Holder submits a
Notice of Conversion (or is deemed to submit such notice pursuant to Section
IV.H) and the Company fails for any reason (other than because such issuance
would exceed such Holder's allocated portion of the Cap Amount, for which
failure the Holders shall have the remedies set forth elsewhere herein) to
deliver, on or prior to the expiration of the Delivery Period for such
conversion, such number of shares of Common Stock to which such Holder is
entitled upon such conversion, or (y) the Company provides notice (including by
way of public announcement) to any Holder at any time of its intention not to
issue shares of Common Stock upon exercise by any Holder of its conversion
rights in accordance with the terms of this Certificate of Designation (other
than because such issuance would exceed such Holder's allocated portion of the
Cap Amount) (each of (x) and (y) being a "Conversion Default"), then the Company
shall pay to the affected Holder, in the case of a Conversion Default described
in clause (x) above, and to all Holders, in the case of a Conversion Default
described in clause (y) above, an amount in cash equal to (i) one percent (1%)
of the Face Amount of the Preferred Stock with respect to which the Conversion
Default exists (which amount shall be deemed to be the aggregate Face Amount of
all outstanding Preferred Stock in the case of a Conversion Default described in
clause (y) above) for each day such Conversion Default exists, not to exceed
fifteen percent (15%) of the Face Amount of the affected Preferred Stock in the
aggregate, (ii) plus any accrued but unpaid Premium with respect thereto. The
payments to which a Holder shall be entitled pursuant to this Article VII. are
referred to herein as "Conversion Default Payments." Conversion Default Payments
shall be made no later than the fifth (5th) business day following written
demand by a Holder for payment therefor and otherwise in accordance with and
subject to the provisions of Section XIV.E. Notwithstanding the foregoing, the
Company shall not be obligated to make Conversion Default Payments if the
applicable Conversion Default results solely from the Company's failure to
obtain Stockholder Approval or failure to have authorized under its Certificate
of Incorporation and available for issuance a sufficient number of shares of
Common Stock to permit the conversion of Preferred Stock subject to a Notice of
Conversion.

         B. Adjustment to Conversion Price. If a Holder has not received
certificates for all shares of Common Stock prior to the tenth (10th) day after
the expiration of the Delivery Period with respect to a conversion of Preferred
Stock for any reason (other than because such issuance would exceed such
Holder's allocated portion of the Cap Amount, for which failure the Holders
shall have the remedies set forth elsewhere herein), then the Conversion Price
in respect of any shares of Preferred Stock held by the affected Holder, in the
case of a Conversion Default of the type described in clause (x) of Section
VII.A, or by all Holders, in the case of a Conversion Default of the type
described in clause (y) of Section VII.A, shall thereafter be reduced by five
percent (5%) per month (prorated for days less than a month) during the period
beginning on, and including, such date of Conversion Default through and
including the day on which such

                                      -8-
<PAGE>   9

Conversion Default is cured; provided that (i) such Conversion Price shall not
be adjusted to less than $1.00 per share pursuant to this Section VII.B unless
the fifteen percent limitation in Section VII.A above is applicable to
Conversion Default Payments and the Closing Bid Price is less than $1.00 for any
day on which a Conversion Default exists, in which case there shall be no such
limitation on such Conversion Price. Notwithstanding the foregoing, the
Conversion Price shall not be adjusted pursuant to this Section VII.B if the
applicable Conversion Default results solely from the Company's failure to
obtain Stockholder Approval or failure to have authorized under its Certificate
of Incorporation and available for issuance a sufficient number of shares of
Common Stock to permit the conversion of Preferred Stock subject to a Notice of
Conversion.

                     VIII. REDEMPTION DUE TO CERTAIN EVENTS

         A. Redemption Events. A "Redemption Event" means any one of the
following:

               (i) the Company fails, and any such failure continues uncured for
ten (10) days after the Company has been notified thereof in writing by the
Holder, to remove any restrictive legend on any certificate or any shares of
Common Stock issued to the Holders of Preferred Stock or Warrants upon
conversion of the Preferred Stock or Warrants (as the case may be) as and when
required by this Certificate of Designation, the Securities Purchase Agreements,
or the Registration Rights Agreements, dated as of February 2, 2001, by and
between the Company and each purchaser of Preferred Stock (the "Registration
Rights Agreements");

               (ii) the Company's failure to deliver shares of Common Stock upon
the expiration of the Delivery Period for any reason; or

(iii) the Company fails to obtain the Stockholder Approval on or before May 31,
2001.

         B. Redemption By Holder. Upon the occurrence of a Redemption Event,
each Holder shall have the right to elect at any time and from time to time by
delivery of a Redemption Notice (as defined herein) to the Company to require
the Company to purchase for cash for an amount per share equal to the Redemption
Amount (as defined herein) any or all of the then outstanding shares of
Preferred Stock held by such Holder.

         C. Definition of Redemption Amount. The "Redemption Amount" with
respect to a share of Preferred Stock for which a demand is being made means (x)
in the case of a Redemption Event pursuant to either of clauses (i) or (ii) of
Section VIII.A above, an amount equal to the greater of (i) the Face Amount of
such Preferred Stock and (ii) an amount determined by the following formula:

         ((Face Amount + Premium)/CP) X Price;

         and (y) in the case of a Redemption Event pursuant to clause (iii) of
Section VIII.A above, an amount equal to the following formula:

         Face Amount + Premium;

                                      -9-
<PAGE>   10

         where;

         "CP" means the Conversion Price in effect on the date of the Redemption
Notice; and

         "Price" means the Closing Bid Price of the Company's Common Stock on
the date of the Redemption Notice.

         D. Redemption Defaults. The Company shall pay a Holder the Redemption
Amount, in cash, with respect to each share of Preferred Stock which is subject
to a written notice electing such redemption (a "Redemption Notice") within five
(5) business days of the Company's receipt of such Redemption Notice. In the
event the Company is not able to purchase all of the shares of Preferred Stock
subject to Redemption Notices, the Company shall redeem shares of Preferred
Stock from a Holder pro rata, based on the total number of shares of Preferred
Stock included by such Holder in its Redemption Notice relative to the total
number of shares of Preferred Stock in all Redemption Notices; provided the
foregoing shall not be deemed to limit the Company's obligation to purchase
shares of Preferred Stock hereunder.

         E. [INTENTIONALLY OMITTED.]

         F. Capital Impairment. In the event that Section 160 of the Delaware
General Corporation Law ("GCL"), would be violated by the redemption of any
shares of Preferred Stock that are otherwise subject to redemption pursuant to
this Article VIII, the Company: (i) will redeem the greatest number of shares of
Preferred Stock possible without violation of said Section; (ii) the Company
thereafter shall use its best efforts to take all necessary steps permitted
pursuant to this Certificate of Designation and the agreements entered into in
connection with the issuance of Preferred Stock pursuant thereto in order to
remedy its capital structure in order to allow further redemptions without
violation of said remaining Section (and not take any action inconsistent with
so remedying such capital structure); and (iii) from time to time thereafter as
promptly as possible the Company shall redeem remaining shares of Preferred
Stock at the request of the Holders to the greatest extent possible without
causing a violation of Section 160 of the GCL (such redemption to be at the
greater of the Redemption Price in effect at the time of the original Redemption
Event giving rise to such violation and the redemption price which would be
applicable for a Redemption Event at the time of such later election under this
clause (iii)). In the event the Company is not able to redeem all the shares of
the stock subject to Redemption Notices, the Company shall redeem shares of
Preferred Stock from a Holder pro rata, based on the total number of shares of
Preferred Stock included by such Holder in the Redemption Notice relative to the
total number of Preferred Stock in all Redemption Notices. In addition, and
notwithstanding anything to the contrary contained in this Section VIII.F, so
long as the Company is prevented from redeeming shares of Preferred Stock
pursuant to this Section VIII.F, the Company shall be (and shall be deemed to
be) in breach of the redemption obligations set forth in this Article VIII and a
Holder shall have all rights and remedies under this Certificate of Designations
or otherwise at law for damages, with respect to such breach.

                                      -10-
<PAGE>   11

                            IX. RANK; PARTICIPATION

         A. Rank. All shares of the Preferred Stock shall rank (i) prior to the
Common Stock; (ii) prior to any other class of capital stock of the Company now
outstanding and prior to any class or series of capital stock of the Company
hereafter created (unless, with the consent of the Holders obtained in
accordance with Article XIII hereof, such class or series of capital stock
specifically, by its terms, ranks senior to or pari passu with the Preferred
Stock) (collectively, with the Common Stock, "Junior Securities"); (iii) pari
passu with any class or series of capital stock of the Company hereafter created
(with the consent of the Holders obtained in accordance with Article XIII
hereof) specifically ranking, by its terms, on parity with the Preferred Stock
(the "Pari Passu Securities"); and (iv) junior to any class or series of capital
stock of the Company hereafter created (with the consent of the Holders obtained
in accordance with Article XIII hereof) specifically ranking, by its terms,
senior to the Preferred Stock (the "Senior Securities"), in each case as to
dividends or distribution of assets upon liquidation, dissolution or winding up
of the Company, whether voluntary or involuntary.

         B. Participation. Subject to the rights of the holders (if any) of Pari
Passu Securities and Senior Securities, the Holders shall, as Holders of
Preferred Stock, be entitled to such dividends paid and distributions made to
the holders of Common Stock to the same extent as if such Holders had converted
such Preferred Stock into Common Stock (without regard to any limitations on
conversion herein or elsewhere contained) and had such Common Stock been issued
and outstanding on the record date for said dividend or distribution. Payments
under the preceding sentence shall be made concurrently with the dividend or
distribution to the holders of Common Stock.

                           X. LIQUIDATION PREFERENCE

         A. Liquidation of the Company. If a Bankruptcy Event shall occur and,
on account of any such event, the Company shall liquidate, dissolve or wind up,
or if the Company shall otherwise liquidate, dissolve or wind up (a "Liquidation
Event"), no distribution shall be made to the holders of any shares of capital
stock of the Company (other than Senior Securities) upon liquidation,
dissolution or winding up unless prior thereto each holder shall have received
the Liquidation Preference (as herein defined) with respect to each share of
Preferred Stock. If, upon the occurrence of a Liquidation Event, the assets and
funds available for distribution among the Holders and holders of Pari Passu
Securities shall be insufficient to permit the payment to such Holders of the
preferential amounts payable thereon, then the entire assets and funds of the
Company legally available for distribution to the Preferred Stock and the Pari
Passu Securities shall be distributed ratably among such shares in proportion to
the ratio that the Liquidation Preference payable on each such share bears to
the aggregate Liquidation Preference payable on all such shares.

         B. Certain Acts Not a Liquidation. The purchase or redemption by the
Company of stock of any class, in any manner permitted by law, shall not, for
the purposes hereof, be regarded as a liquidation, dissolution or winding up of
the Company. Neither the consolidation or merger of the Company with or into any
other entity nor the sale or transfer by the Company

                                      -11-
<PAGE>   12

of less than substantially all of its assets shall, for the purposes hereof, be
deemed to be a liquidation, dissolution or winding up of the Company.

         C. Definition of Liquidation Preference. The "Liquidation Preference"
with respect to a share of Preferred Stock means an amount equal to the Face
Amount thereof plus the Premium with respect thereto plus any other amounts that
may be due from the Company with respect thereto through the date of final
distribution. The Liquidation Preference with respect to any Pari Passu
Securities shall be as set forth in the charter of the Company.

          XI. ADJUSTMENTS TO THE CONVERSION PRICE; CERTAIN PROTECTIONS

         The Conversion Price shall be subject to adjustment from time to time
as follows:

         A. Stock Splits, Stock Dividends, Etc. If at any time on or after the
First Closing, the number of outstanding shares of Common Stock is increased by
a stock split, stock dividend, combination, reclassification or other similar
event, the Conversion Price shall be proportionately reduced, or if the number
of outstanding shares of Common Stock is decreased by a reverse stock split,
combination or reclassification of shares, or other similar event, the
Conversion Price shall be proportionately increased.

         B. Major Transactions.

               (i) If the Company shall consolidate with or merge into any
corporation or reclassify its outstanding shares of Common Stock (other than by
way of subdivision or reduction of such shares) or if there shall occur any
share exchange pursuant to which all of the outstanding shares of Common Stock
are converted into other securities or property, then each Holder shall
thereafter be entitled to receive consideration, in exchange for each share of
Preferred Stock held by it, equal to the greater of, as determined in the sole
discretion of such Holder: (x) the number of shares of stock or securities or
property of the Company, or of the entity resulting from such transaction, to
which a Holder of the number of shares of Common Stock delivered upon conversion
of such shares of Preferred Stock would have been entitled upon such transaction
had the Holder exercised its right of conversion (without regard to any
limitations on conversion herein or elsewhere contained) on the trading date
immediately preceding the public announcement of such transaction and had such
Common Stock been issued and outstanding and had such Holder been the holder of
record of such Common Stock at the time of the consummation of such transaction,
and (y) 125% of the Face Amount of such shares of Preferred Stock in cash; and
the Company shall make lawful provision therefor as a part of such transaction.

               (ii) If, in connection with a business acquisition or a series of
business acquisitions occurring within any six (6) month period the Company
shall issue capital stock representing in excess of twenty percent (20%) of its
Common Stock outstanding immediately prior to such issuance (determined on a
fully-diluted basis), or if the Company shall sell all or substantially all of
its assets, then each Holder shall, at the option of each such Holder, be
entitled to receive consideration, in exchange for each share of Preferred Stock
held by it, in an

                                      -12-
<PAGE>   13

amount equal to 125% of the Face Amount of such shares of Preferred Stock in
cash, and the Company shall make lawful provision therefor as a part of such
transaction.

               (iii) No sooner than ten (10) business days nor later than five
(5) business days prior to the consummation of any transaction of a sort
described in paragraphs (i) or (ii) above, but not prior to the public
announcement of any such transaction, the Company shall deliver written notice
("Notice of Major Transaction") to each Holder, which Notice of Major
Transaction shall be deemed to have been delivered one (1) business day after
the Company's sending such notice by telecopy (provided that the Company sends a
confirming copy of such notice on the same day by overnight courier) of such
Notice of Major Transaction. Such Notice of Major Transaction shall indicate the
amount and type of the consideration which such Holder would receive under
clause (i) of this Section XI.B.

               (iv) Notwithstanding anything in this Section XI.B which may be
to the contrary, if following a transaction which triggers the applicability of
paragraphs (i) or (ii), the Common Stock remains outstanding or holders of
Common Stock receive any common stock or substantially similar equity interest,
in each of the foregoing cases which is publicly traded, each Holder may, at its
option in lieu of receiving the consideration set forth in paragraphs (i) or
(ii) above, as applicable, retain its Preferred Stock and such Preferred Stock
shall continue to apply to such Common Stock or shall apply, as nearly as
practicable, to such other common stock or equity interest, as the case may be.

         C. Adjustment of Conversion Price upon Dilutive Issuance.

               (i) Issuance of Common Stock at a Price below the Conversion
Price. Except as otherwise provided in Section A or B of this Article or in this
Section C, if, at any time after the First Closing, the Company issues or sells,
or in accordance with Section C(ii) hereof is deemed to have issued or sold
(except (a) upon the exercise of any warrants, options or convertible securities
granted, issued and outstanding on the date of issuance of this Preferred Stock;
(b) upon the grant, purchase or exercise of any stock or options which may
hereafter be granted, purchased or exercised under any stock option or employee
stock purchase plan of the Company now existing or to be implemented in the
future, so long as the issuance of such stock or options is approved by a
majority of the independent members of the board of directors of the Company or
a majority of the members of a committee of independent directors established
for such purpose; (c) upon the exercise of the Warrants pursuant to their terms
and the conversion of the Preferred Stock pursuant to this Certificate of
Designation; (d) upon the issuance of Common Stock pursuant to a bona fide, firm
commitment underwritten public offering registered under the Securities Act
pursuant to an effective registration statement; (e) upon the issuance of Common
Stock to independent contractors or consultants pursuant to written agreements
existing on the date of the First Closing and disclosed in the Schedule of
Exceptions to the Securities Purchase Agreements; (f) upon the issuance of
equity securities in connection with bank credit agreements and equipment lease
lines, the primary purpose of which is not to raise equity capital; (g) upon the
issuance of Common Stock pursuant to or in connection with a strategic alliance,
partnering relationship, or a bona fide business acquisition of or by the
Company, whether by merger, joint venture, consolidation, sale of assets, sale
or exchange of stock or otherwise, regarding which the Company has obtained a
fairness opinion from a nationally recognized investment banking firm or
regarding which an appropriate officer of the Company has certified to the
Holders that the

                                      -13-
<PAGE>   14

board of directors of the Company has determined in its reasonable business
judgment that the Company has received in such transaction the fair value for
the shares issued therefor, or (h) upon the issuance of securities otherwise to
the Holders pursuant to the Securities Purchase Agreements), any shares of
Common Stock for no consideration or for a consideration per share less than the
then current Conversion Price (a "Dilutive Issuance"), then effective
immediately upon the Dilutive Issuance, the Conversion Price will be adjusted in
accordance with the following formula:

         C' = (C)[(O + P/C) / (CSDO)]

         where:

         C'=       the adjusted Conversion Price

         C=        the Conversion Price in effect prior to the
                   Dilutive Issuance;

         O=        the number of shares of Common Stock outstanding
                   immediately prior to the Dilutive Issuance;

         P=        the aggregate consideration, calculated as set
                   forth in Section C(ii) hereof, received by the
                   Company upon such Dilutive Issuance; and

         CSDO=     the total number of shares of Common Stock Deemed
                   Outstanding (as herein defined) immediately after
                   the Dilutive Issuance.

         "Common Stock Deemed Outstanding" shall mean the number of shares of
     Common Stock actually outstanding (not including shares of Common Stock
     held in the treasury of the Company), plus (x) in case of any adjustment
     required by Section XI.C resulting from the issuance of any Options, the
     maximum total number of shares of Common Stock issuable upon the exercise
     of the Options for which the adjustment is required (including any Common
     Stock issuable upon the conversion of Convertible Securities issuable upon
     the exercise of such Options), and (y) in the case of any adjustment
     required by Section XI.C resulting from the issuance of any Convertible
     Securities, the maximum total number of shares of Common Stock issuable
     upon the exercise, conversion or exchange of the Convertible Securities for
     which the adjustment is required, as of the date of issuance of such
     Convertible Securities, if any.

               (ii) Effect on Conversion Price of Certain Events. For purposes
of determining the adjusted Conversion Price under Section C(i) hereof, the
following will be applicable:

                    (a) Issuance of Rights or Options. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities exercisable, convertible into or exchangeable for Common Stock
("Convertible Securities"), but not to include the grant or exercise of any
stock or options which may hereafter be granted or exercised under any of the
Company's stock option plan or employee stock purchase plan now existing or to
be implemented in the future (so long as the issuance of such stock or options
is approved by a committee of independent directors of the Company established
for this purpose) (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred

                                      -14-
<PAGE>   15

to as "Options"), and the price per share for which Common Stock is issuable
upon the exercise of such Options is less than the Conversion Price on the date
of issuance ("Below Market Options"), then the maximum total number of shares of
Common Stock issuable upon the exercise of all such Below Market Options
(assuming full exercise, conversion or exchange of Convertible Securities, if
applicable) will, as of the date of the issuance or grant of such Below Market
Options, be deemed to be outstanding and to have been issued and sold by the
Company for such price per share. For purposes of the preceding sentence, the
price per share for which Common Stock is issuable upon the exercise of such
Below Market Options is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or
granting of such Below Market Options, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the exercise of
all such Below Market Options, plus, in the case of Convertible Securities
issuable upon the exercise of such Below Market Options, the minimum aggregate
amount of additional consideration payable upon the exercise, conversion or
exchange thereof at the time such Convertible Securities first become
exercisable, convertible or exchangeable, by (ii) the maximum total number of
shares of Common Stock issuable upon the exercise of all such Below Market
Options (assuming full conversion of Convertible Securities, if applicable).
Except as contemplated hereinbelow, no further adjustment to the Conversion
Price will be made upon the actual issuance of such Common Stock upon the
exercise of such Below Market Options or upon the exercise, conversion or
exchange of Convertible Securities issuable upon exercise of such Below Market
Options.

                    (b) Issuance of Convertible Securities.

                    (1) If the Company in any manner issues or sells any
Convertible Securities, whether or not immediately convertible (other than where
the same are issuable upon the exercise of Options) and the price per share for
which Common Stock is issuable upon such exercise, conversion or exchange (as
determined pursuant to Section C(ii)(b)(2) if applicable) is less than the
Conversion Price on the date of issuance, then the maximum total number of
shares of Common Stock issuable upon the exercise, conversion or exchange of all
such Convertible Securities will, as of the date of the issuance of such
Convertible Securities, be deemed to be outstanding and to have been issued and
sold by the Company for such price per share. For the purposes of the preceding
sentence, the price per share for which Common Stock is issuable upon such
exercise, conversion or exchange is determined by dividing (i) the total amount,
if any, received or receivable by the Company as consideration for the issuance
or sale of all such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the exercise,
conversion or exchange thereof at the time such Convertible Securities first
become exercisable, convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or
exchange of all such Convertible Securities. Except as contemplated hereinbelow,
no further adjustment to the Conversion Price will be made upon the actual
issuances of such Common Stock upon exercise, conversion or exchange of such
Convertible Securities.

                    (2) If the Company in any manner issues or sells any
Convertible Securities with a conversion or exercise price or exchange ratio
which fluctuates on a daily basis (a "Floating Rate Convertible Security"), then
the price per share for which Common Stock is

                                      -15-
<PAGE>   16

issuable upon such exercise, conversion or exchange for purposes of the
calculation contemplated by Section C(ii)(b)(1) shall be deemed to be the
greater of (A) the lowest of (x) fifty percent (50%) of the Closing Bid Price on
the date of the such issuance; (y) the initial conversion or exercise price of
such Floating Rate Convertible Security on the date of such issuance, assuming
it is convertible or exercisable on the date of such issuance; and (z) eighty
five percent (85%) of the Conversion Price on the date of such issuance, and (B)
any minimum conversion or exercise price which is applicable to such Floating
Rate Convertible Security in all events (i.e., a Floor).

                    (c) Change in Option Price or Conversion Rate. Subject to
subsection (ii)(b)(2) above and except for the grant or exercise of any stock or
options which may hereafter be granted or exercised under any of the Company's
stock option plans or employee stock purchase plan now existing or to be
implemented in the future provided the issuance of such stock or options is
approved by a committee of independent directors of the Company, if there is a
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange or any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock
(other than under or by reason of provisions designed to protect against
dilution), the Conversion Price in effect at the time of such change will be
readjusted to the Conversion Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold.

                    (d) Treatment of Expired Options and Unexercised Convertible
Securities. If, in any case, the total number of shares of Common Stock issuable
upon exercise of any Options or upon exercise, conversion or exchange of any
Convertible Securities is not, in fact, issued and the rights to exercise such
option or to exercise, convert or exchange such Convertible Securities shall
have expired or terminated, the Conversion Price then in effect will be
readjusted to the Conversion Price which would have been in effect at the time
of such expiration or termination had such Options or Convertible Securities, to
the extent outstanding immediately prior to such expiration or termination
(other than in respect of the actual number of shares of Common Stock issued
upon exercise or conversion thereof), never been issued.

                    (e) Calculation of Consideration Received. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Certificate of
Designation will be the amount received by the Company therefor, before
deduction of reasonable commissions, underwriting discounts or allowances or
other reasonable expenses paid or incurred by the Company in connection with
such issuance, grant or sale. In case any Common Stock, Options or Convertible
Securities are issued or sold for a consideration part or all of which shall be
other than cash, the amount of the consideration other than cash received by the
Company will be the fair market value of such consideration except where such
consideration consists of freely-tradable securities, in which case the amount
of consideration received by the Company will be the fair market price thereof
as of the date of receipt. In case any Common Stock, Options or Convertible
Securities are issued in connection with any merger or consolidation in which
the Company is the surviving

                                      -16-
<PAGE>   17

corporation (or the parent thereof), the amount of consideration therefor will
be deemed to be the fair market value of such portion of the net assets and
business of the non-surviving corporation as is attributable to such Common
Stock, Options or Convertible Securities, as the case may be. The fair market
value of any consideration other than cash or securities will be determined in
the good faith reasonable business judgment of the Board of Directors.

         D. Purchase Rights. If at any time after the First Closing, the Company
issues any Convertible Securities or rights to purchase stock, warrants,
securities or other property (the "Purchase Rights") pro rata to the record
holders of any class of Common Stock, then the Holders will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which such Holder could have acquired if such Holder had held
the number of shares of Common Stock acquirable upon complete conversion of the
Preferred Stock (without regard to any limitations on conversion or exercise
herein or elsewhere contained) immediately before and on the date on which a
record is taken for the grant, issuance or sale of such Purchase Rights, or, if
no such record is taken, the date as of which the record holders of Common Stock
are to be determined for the grant, issue or sale of such Purchase Rights.

         E. Special Adjustment. If the Company takes any actions (including
under or by virtue of this Article XI) which would have a dilutive effect on the
Holder or which would materially and adversely affect the Holder with respect to
its investment in the Preferred Stock, and if the provisions of this Article XI
are not strictly applicable to such actions or, if applicable to such actions,
would not operate to equitably protect the Holder against such actions, then the
Company shall promptly upon notice from a Holder appoint its independent
certified public accountants to determine as promptly as practicable an
appropriate adjustment to the terms hereof or another appropriate action to so
equitably protect such Holder and prevent any such dilution and any such
material adverse effect, as the case may be. Following such determination, the
Company shall forthwith make the adjustments or take the other actions described
therein.

         F. Notice of Adjustments. Upon the occurrence of each adjustment or
readjustment pursuant to this Article XI, the Company, at its expense, shall
promptly compute such adjustment or readjustment and prepare and furnish to each
Holder a certificate setting forth such adjustment or readjustment and showing
in detail the facts upon which such adjustment or readjustment is based. The
Company shall, upon the written request at any time of any Holder, furnish to
such Holder a like certificate setting forth (i) such adjustment or
readjustment, (ii) the Conversion Price at the time in effect and (iii) the
number of shares of Common Stock and the amount, if any, of other securities or
property which at the time would be received upon conversion of a share of
Preferred Stock.

         G. Key Officer and Director Transfers. If any Key Officer (as defined
below) or director of the Company, during the period beginning on the Closing
and ending on the date that is six (6) months after the Registration Statement
required pursuant to Section 2.1 of the Registration Rights Agreements is
declared effective (provided that such period shall be extended to the extent of
any Registration Suspension and Listing Suspension (each as defined in the
Registration Rights Agreements)) (the "Transfer Period"), and while such person
is a Key Officer or director, directly or indirectly, offers, sells, transfers,
assigns, pledges, hedges or otherwise disposes of any shares of Common Stock, or
any Options to purchase or acquire shares

                                      -17-
<PAGE>   18

of Common Stock or enters into any agreement, contract, arrangement or
understanding with respect to any such offer, sale, transfer, assignment,
pledge, hedge or other disposition of any Common Stock or Options or provides or
files any public notice, including pursuant to Rule 144 of the Securities Act,
of a bona fide intent to dispose of a specified amount of Common Stock or
Options (an "Executive Transfer"), then the Conversion Price for Holders other
than Key Officers in effect at the time of each such Executive Transfer shall be
reduced by ten percent (10%) of that amount otherwise calculated pursuant hereto
provided, however that a Key Officer or director may sell in the aggregate
during the portion of the Transfer Period which portion commences on the date
which is three (3) months following the effectiveness of such Registration
Statement up to 10 percent (10%) of his or her total holdings of Common Stock on
a fully diluted basis as of the First Closing at prices not less than the
initial Conversion Price (subject to equitable adjustments for any stock split,
combinations, stock dividends, reclassifications or similar events) without
triggering the adjustments of this Section. Any of the foregoing transactions
entered into by any member of a director's or Key Officer's family or by any
trust or other entity for the benefit of any such director or Key Officer or any
member of his or her family or by any affiliate of such director or Key Officer
or any of the other foregoing persons, trusts or entities, shall be treated for
purposes of this section as a transaction by such director or Key Officer. For
purposes of this Section, Key Officers shall mean the individuals listed on
Schedule 3.18 of the Securities Purchase Agreements and any person who assumes
or performs the duties of any Key Officer. For purposes of clarification, and
without implication that the contrary would otherwise be true, each such
Executive Transfer during the Transfer Period shall result in a reduction of the
Conversion Price by 10% and such reductions, in addition to any other
adjustments to the Conversion Price pursuant to this Certificate of Designation,
shall be cumulative. For example, if a Key Officer makes an Executive Transfer
when the Conversion Price is $10.00, the Conversion Price for Holders other than
Key Officers would be reduced to $9.00. If the Common Stock subsequently
undergoes a two-for-one split, the Conversion Price would be reduced to $4.50.
If, subsequent to the split, the same or another Key Officer makes an Executive
Transfer, the Conversion Price for Holders other than Key Officers would be
further reduced to $4.05. Notwithstanding the foregoing, any Key Officer or
director shall be entitled to make Permitted Transfers (as defined below)
without limitation and any Permitted Transfer shall not be included in any
computation of the 10% limitation set forth in this paragraph. The term
"Permitted Transfer" shall mean any assignment, gift or other transfer to any
child, spouse or other family member or trust for the benefit of any family
member, provided that further transfers by any such transferees shall continue
to be subject to this Section XI.G; or (ii) any bona fide gift to any charitable
organization.

                               XII. VOTING RIGHTS

         The holders of Preferred Stock shall have no voting power whatsoever,
except as otherwise provided by applicable law.

         Notwithstanding the above, the Company shall provide each Holder with
prior notification of any meeting of the stockholders (and copies of proxy
materials and all other information sent to stockholders). If the Company takes
a record of its stockholders for the purpose of determining stockholders
entitled to (a) receive payment of any dividend or other distribution, any right
to subscribe for, purchase or otherwise acquire (including by way of

                                      -18-
<PAGE>   19

merger, consolidation or recapitalization) any share of any class or any other
securities or property, or to receive any other right, or (b) to vote in
connection with any proposed sale, lease or conveyance of all or substantially
all of the assets of the Company, or any proposed merger, consolidation,
liquidation, dissolution or winding up of the Company, the Company shall mail a
notice to each Holder, at least twenty (20) days prior to the record date
specified therein (or thirty (30) days prior to the consummation of the
transaction or event, whichever is earlier, but in no event earlier than public
announcement of such proposed transaction), of the date on which any such record
is to be taken for the purpose of such vote, dividend, distribution, right or
other event, and a brief statement regarding the amount and character of such
vote, dividend, distribution, right or other event to the extent known at such
time.

         To the extent that under applicable law the vote of the holders of the
Preferred Stock, voting separately as a class or series, as applicable, is
required to authorize a given action of the Company, the affirmative vote or
consent of the Holders of at least a majority of the shares of the Preferred
Stock represented at a duly held meeting at which a quorum is present or by
written consent of a majority in interest of the Preferred Stock then
outstanding (except as otherwise may be required by applicable law) shall
constitute the approval of such action by the class. To the extent that under
applicable law Holders are entitled to vote on a matter with holders of Common
Stock, voting together as one class, each share of Preferred Stock shall be
entitled to a number of votes equal to the number of shares of Common Stock into
which it is then convertible (without giving effect to any limitation on
conversion with respect thereto) using the record date for the taking of such
vote of stockholders as the date as of which the Conversion Price is calculated.

                          XIII. PROTECTION PROVISIONS

         The Company shall not, without first obtaining the approval of Holders
of two-thirds of the outstanding Preferred Stock: (a) alter or change the
rights, preferences or privileges of the Preferred Stock; (b) alter or change
the rights, preferences or privileges of any capital stock of the Company so as
to affect adversely the Preferred Stock; (c) create any Senior Securities; (d)
create any Pari Passu Securities; (e) increase the authorized number of shares
of Preferred Stock; (f) redeem, or declare or pay any cash dividend or
distribution on, any Junior Securities; or (g) do any act or thing not
authorized or contemplated by this Certificate of Designations which would
result in any taxation with respect to the Preferred Stock under Section 305 of
the Internal Revenue Code of 1986, as amended, or any comparable provision of
the Internal Revenue Code as hereafter from time to time amended (or otherwise
suffer to exist any such taxation as a result of said Section or comparable
provisions). The Company shall not issue additional shares of Preferred Stock
except to effect the purchase and sale to the Holders in accordance with the
Securities Purchase Agreements and as contemplated by this Certificate of
Designation.

                               XIV. MISCELLANEOUS

         A. Cancellation of Preferred Stock. If any shares of Preferred Stock
are converted pursuant to Article IV, the shares so converted shall be canceled,
shall return to the status of

                                      -19-
<PAGE>   20

authorized but unissued preferred stock of no designated series, and shall not
be issuable by the Company as Preferred Stock.

         B. Lost or Stolen Certificates. Upon receipt by the Company of (i)
evidence of the loss, theft, destruction or mutilation of any Preferred Stock
Certificate(s) and (ii) (x) in the case of loss, theft or destruction, of
indemnity reasonably satisfactory to the Company, or (y) in the case of
mutilation, upon surrender and cancellation of the Preferred Stock
Certificate(s), the Company shall execute and deliver new Preferred Stock
Certificate(s) of like tenor and date. However, the Company shall not be
obligated to reissue such lost or stolen Preferred Stock Certificate(s) if the
Holder contemporaneously requests the Company to convert such Preferred Stock.

         C. Allocation of Cap Amount and Reserved Amount. A portion of the
initial Reserved Amount and the initial Cap Amount shall be allocated to a
Holder in the same proportion as the number of shares of Preferred Stock issued
to such Holder bears to the aggregate number of outstanding shares of Preferred
Stock. A portion of each increase to the Reserved Amount or the Cap Amount and a
portion of the Reserved Amount or the Cap Amount which remains allocated to any
person or entity which does not hold any Preferred Stock shall be allocated pro
rata to each Holder based on the number of shares of Preferred Stock held by
such Holder in relation to all outstanding shares of Preferred Stock at the time
of the increase in or reallocation of the Reserved Amount or the Cap Amount. In
the event a Holder shall sell or otherwise transfer any of such Holder's shares
of Preferred Stock, each transferee shall be allocated a pro rata portion of
such transferor's Reserved Amount and Cap Amount.

         D. Statements of Available Shares. Upon request of a Holder, the
Company shall deliver to such Holder a written report notifying the Holder (i)
of any occurrence which prohibits the Company from issuing Common Stock upon any
such conversion, (ii) the total number of shares of Preferred Stock outstanding
as of the date of the request, (iii) the total number of shares of Common Stock
issued upon all conversions of Preferred Stock through the date of the request,
(iv) the total number of shares of Common Stock which are reserved for issuance
upon conversion of the Preferred Stock as of the date of the request, and (v)
the total number of shares of Common Stock which may thereafter be issued by the
Company upon conversion of the Preferred Stock before the Company would exceed
the Reserved Amount and the Cap Amount. The Company shall, within ten (10) days
after delivery to the Company of a written request by any Holder, provide all of
the information and make simultaneous public disclosure thereof.

         E. Payment of Cash; Defaults. Whenever the Company is required to make
any cash payment to a Holder under this Certificate of Designation, such cash
payment shall be made to the Holder by the method (by certified or cashier's
check or wire transfer of immediately available funds) elected by such Holder.
If such payment is not delivered when due such Holder shall thereafter be
entitled to interest on the unpaid amount at a per annum rate equal to the lower
of twenty-four percent (24%) or the highest interest rate permitted by
applicable law until such amount is paid in full to the Holder.

         F. Status as Stockholder. Upon submission of a Notice of Conversion by
a Holder of Preferred Stock, the shares covered thereby shall be deemed
converted into shares of Common Stock in accordance with the terms hereof and
the Holder's rights as a Holder of such converted

                                      -20-
<PAGE>   21

shares of Preferred Stock shall cease and terminate, excepting only the right to
receive certificates for such shares of Common Stock and to any rights and
remedies provided herein or otherwise available at law or in equity to such
Holder because of a failure by the Company to comply with the terms of this
Certificate of Designation, whether prior to or in connection with such
conversion.

         G. Remedies, Characterizations, Other Obligations, Breaches and
Injunctive Relief. The remedies provided in this Certificate of Designation
shall be cumulative and in addition to all other remedies available under this
Certificate of Designation, at law or in equity (including a decree of specific
performance and/or other injunctive relief), no remedy contained herein shall be
deemed a waiver of compliance with the provisions giving rise to such remedy and
nothing herein shall limit a Holder's right to actual damages for any failure by
the Company to comply with the terms of this Certificate of Designation
(including, without limitation, damages incurred to effect "cover" of shares of
Common Stock anticipated to be received upon a conversion hereunder but not
received in accordance with the terms hereof). The Company covenants to Holder
that there shall be no characterization concerning this instrument other than as
consistent with the express terms provided herein. Amounts set forth or provided
for herein with respect to payments, conversion and the like (and the
computation thereof) shall be the amounts to be received by the Holder and shall
not, except as expressly provided herein, be subject to any other obligation of
the Company (or the performance thereof). The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the holders of
Preferred Stock and that the remedy at law for any such breach may he
inadequate. The Company therefore agrees that, in the event of any such breach
or threatened breach, the Holders shall be entitled, in addition to all other
available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being
required.

         H. Specific Shall Not Limit General; Construction. No specific
provision contained in this Certificate of Designation shall limit or modify any
more general provision contained herein. This Certificate of Designation shall
be deemed to be jointly drafted by the Company and all Holders and shall not be
construed against any person as the drafter hereof.

         I. Failure or Indulgence Not Waiver. No failure or delay on the part of
a Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, not shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.
