                     NOTES TO UNAUDITED FINANCIAL STATEMENTS

Note 1. BASIS OF PRESENTATION
In the opinion of the management of Quantech, the accompanying unaudited
financial statements contain all adjustments (consisting of only normal,
recurring adjustments) necessary to present fairly the financial position of
Quantech as of September 30, 1999 and the results of operations and its cash
flows for the three month periods ended September 30, 1999 and 1998. The results
of operations for any interim period are not necessarily indicative of the
results for the year. These interim financial statements should be read in
conjunction with Quantech's annual financial statements and related notes in
Quantech's Annual Report on Form 10-KSB for the year ended June 30, 1999.

Note 2. LICENSE AGREEMENT

Quantech has a license agreement with Ares-Serono for certain patents,
proprietary information and associated hardware related to SPR technology. The
license calls for an ongoing royalty of 6 percent on all products utilizing the
SPR technology which are sold by Quantech. In addition, if Quantech sublicenses
the technology, Quantech will pay a royalty of 15 percent of all revenues
received by Quantech under any sublicense. As of December 31, 1998, Quantech had
paid $1,150,000 of cumulative royalty payments. In order to maintain its
exclusive rights under the license agreement, Quantech must make a final
$150,000 payment by December 31, 1999. Quantech accrues quarterly a pro-rata
portion of the $150,000 annual payment, and will continue to do so until royalty
accruals based on revenues exceed such minimum annual payment amount.

Note 3. SERIES A CONVERTIBLE PREFERRED STOCK

In November 1998, Quantech established an additional class of shares as Series A
convertible preferred stock (the "Series A Preferred Stock"), and designated
2,500,000 of its authorized shares as Series A Preferred Stock. As of November
10, 1999 there were 1,620,547 shares of Series A Preferred Stock issued and
outstanding.

ITEM 2                     MANAGEMENT'S DISCUSSION AND ANALYSIS
                                   OR PLAN OF OPERATION

History

         Quantech Ltd. is a Minnesota company originally founded in 1991.
Quantech is completing development of its Hospital Emergency Department Patient
Treatment Information Platform. We refer to this platform as the PTIP. The PTIP
is expected to run tests for a number of different medical conditions and
deliver that test information by wireless communication devices to the Emergency
Department ("ED") staff treating a patient.

         The PTIP consists of an instrument that sits on the top of a counter or
cart and reads disposable test cartridges developed by Quantech. Each Quantech
test cartridge will contain from one to four different medical tests such as
those for a heart attack or pregnancy. The instrument produces test results in a
manner different than other testing systems because it uses Quantech's
proprietary technology based on the scientific phenomenon known as surface
plasmon resonance ("SPR"), which involves the interaction of light with
electrons. Quantech's technology creates SPR in a controlled environment which
enables its instrument to detect and transmit information concerning the
presence and quantity of certain native and foreign molecules in blood, urine or
other fluids which may be associated with specific diseases or medical
conditions. Transmission of this test information to the ED treatment staff will
be performed though the use of a wireless local area network communications
system and handheld receiving devices similar to a pager.

         We are designing the PTIP for the emergency department. It is expected
to have the range of available tests and quality performance of hospitals'
central and STAT labs, but with test time turnaround of 10 to 20 minutes. The
system will analyze both whole blood and urine without preparation or addition
of other substances or removal of the sample from the collection device. We
believe this ease of use and the ability to locate the PTIP in the ED will
economically provide physicians with faster test results than hospital central
or STAT laboratories.

         We expect our system to include an initial menu of more than 20 STAT
tests grouped in patient diagnosis-related panels such as cardiac enzymes (heart
attack), pregnancy, red and white blood cell counts, blood coagulation, kidney
function, pancreas function and electrolytes. Tests for liver functions, drugs
of abuse, therapeutic drugs and additional STAT tests will also be made
available on the system. Quantech's cardiac markers for myoglobin and CK-MB have
received FDA 510(k) approval. A test for pregnancy is being reviewed by the FDA.
The final heart attack marker for Troponin I meets clinical requirements and the
remaining launch menu of tests are in various stages of development.

         The ED is a significant and consolidated market. Current processes for
providing test information to the ED staff are complicated and require a
multitude of steps that greatly increase patient treatment turnaround time. The
challenge is to increase efficiency and decrease costs. Time delays and
interruption of batch testing in the central lab, and the cost of tests run in
STAT labs, have caused both to fall well short of meeting the burden of
providing fast and economic STAT test results. Although there are some
point-of-care STAT testing products available for the ED, they do not have the
required test menu, ease of use, communication capability or quality of results
necessary to streamline the entire ED testing process. The solution is seven day
a week, 24 hour a day disintermediation of the process for providing ED
treatment information. We believe our product will provide this capability.

         Quantech and The Perkin-Elmer Corporation, a leading supplier of life
science systems and analytical instruments, are parties to a technology and
development agreement. This agreement provides Perkin-Elmer with exclusive
licenses to some of our technology for use outside of our core area of medical
diagnostics. We have licensed back from Perkin-Elmer

                                       9
<PAGE>

technology that provides a large density, high throughput diagnostic testing
capacity for our SPR technology. We believe this capability will allow us to
expand our digital SPR technology into central lab, ICU/CCU, surgical suites,
doctor office and home testing markets.

         Quantech is a development stage company which has suffered significant
losses from operations, requires immediate additional financing, and ultimately
needs to complete development of its product, generate revenues, and
successfully attain profitable operations to realize the value of its license
agreement. These factors raise substantial doubt about Quantech's ability to
continue as a going concern.

Results of Operations

         Quantech has incurred a net loss of $23,585,378 from September 30, 1991
(date of inception) through September 30, 1999 due to expenses related to
formation and operation of Quantech's predecessor, Spectrum Diagnostics Inc.
("SDS") in Italy, continuing costs of raising capital, normal expenses of
operating over an extended period of time, funds applied to research and
development, royalty payments related to the SPR technology, losses due to
expenses of SDS and interest on borrowed funds. In addition, an investment of
$3,356,629 was made when Quantech purchased the exclusive rights to the SPR
technology.

         General and administration expenses increased to $601,335 for the three
months ended September 30, 1999 from $306,828 for the same period in 1998
primarily due to market research expenses including fees paid to consultants and
research firms and costs to attend industry trade shows. We expect general and
administrative expenses to increase in the future as we complete development of
our system, prepare for market launch and begin to manufacture and distribute
our products. Quantech will also begin to incur increasing sales and marketing
expenses.

         Research and development costs increased to $591,454 for the three
months ended September 30, 1999 from $528,111 for the same period in 1998
primarily due to increased internal development work. We expect R&D spending to
significantly increase as we complete the commercial development of our system,
conduct additional FDA work, and begin to establish higher volume manufacturing
capabilities.

         Minimum royalty expense of $37,500 was unchanged for the three months
ended September 30, 1999 compared to the same period in 1998. We will continue
to accrue royalty expense of $37,500 per quarter until the final minimum payment
is made in December 1999. In the future we expect to incur additional royalty
expense when royalties based on revenues exceed minimum payments (see Notes to
Financial Statements, Note 2 - License Agreement).

         Interest expense decreased to $9,608 for the quarter ended September
30, 1999 from $671,532 in the same period in 1998 as a result of reduced debt.
Interest expense is expected to remain flat for the remainder of the fiscal year
as Quantech does not anticipate any debt other than borrowing up to $750,000
from its bank credit facility.

         For the three months ended September 30, 1999 Quantech had a loss of
$1,238,514 as compared to $1,543,318 for the same period in 1998 primarily due
to lower interest expense partially offset by higher operating expenses.

         The timetable for submitting additional tests to the FDA and
introduction of Quantech's system to the market will be influenced by Quantech's
ability to obtain further funding, enter into strategic relationships, complete
commercial prototype development of its system and develop further tests, and
delays it may encounter with the FDA in its review of Quantech's tests and
system. There can be no assurance that Quantech will be able to obtain the
required funding, enter into any strategic agreements or ultimately complete its
commercial system.

                                       10

Liquidity and Capital Resources

         From inception to September 30, 1999, Quantech has raised approximately
$22,200,000 through a combination of public stock sales, private stock sales and
debt obligations. Quantech began offering for sale shares of Series B Preferred
Stock in May 1999, and amended the provisions of such stock in October 1999. The
shares are priced at $1.00 per share and each share is convertible into one
share of common stock. In September 1999, Quantech received $500,000 pursuant to
the exercise of a warrant for 454,545 shares of common stock.

         Quantech has minimal cash on hand and requires immediate proceeds from
the sale of additional Series B Preferred Stock to allow it to maintain
operations. Quantech is currently trying to raise $1 million through the sale of
Series B Preferred Stock, which funds if raised in total will allow it to
operate through February 2000. Additional financing of approximately $10 million
will be needed to develop and submit to the FDA additional tests, complete
clinical evaluation of the system, establish manufacturing capabilities and
prepare for sales of the system. Quantech is currently reviewing multiple
avenues of future funding including private sale of equity or debt with equity
features or arrangements with strategic partners. Quantech does not have any
commitments for any such financing and there can be no assurance that Quantech
will obtain additional capital when needed or that additional capital will not
have a dilutive effect on current stockholders. See "Cautionary Statements -- We
need additional cash and will require at least $10 million in additional
financing to complete commercial development of our system and have no
commitment to receive any additional significant funding." Although Quantech has
a limited lending arrangement with its bank to a maximum of $750,000, all of
which credit line will be used by the end of calendar 1999, it does not
anticipate receiving any additional significant funding from commercial lenders.

         Quantech incurred capital expenditures of $31,766 in the three month
period ended September 30, 1999. Quantech anticipates significant capital
expenditures in the future for laboratory and production equipment and office
expansion as Quantech nears product introduction. The timing and amount of such
expenditures will be governed by Quantech's development and market introduction
schedules which are subject to change due to a number of factors including
development delays, FDA approval and availability of future financing.

         As of November 10, 1999 Quantech had 3,538,052 shares of common stock
outstanding. It also had options and warrants outstanding to purchase an
additional 5,372,445 shares at exercise prices from $0.75 to $14.40, and Series
A and B Preferred Stock convertible into 7,863,855 shares of common stock.

Cautionary Statements

         Quantech wishes to caution investors that the following important
factors, among others, in some cases have affected, and in the future could
affect, Quantech's actual results of operations and cause such results to differ
materially from those anticipated in forward-looking statements made in this
document and elsewhere by or on behalf of Quantech.

         We immediately need additional cash and will require at least $10
million in additional financing to complete commercial development of our system
and have no commitment to receive any additional significant funding.

         Quantech does not have sufficient funds to remain in operation, or
complete commercial development or commence production and sales of its system.
Quantech has minimal cash on hand and no more availability on its bank credit
facility. Quantech must immediately complete the sale of its Series B
convertible preferred stock offering for $1 million to maintain current
operations and continue operations through February 2000. Additional financing
of at least $10 million of investment capital, funding by strategic partner(s)
or licensing revenues will be needed for the following: to develop and submit to
the FDA additional tests, complete clinical evaluation of the system, establish
manufacturing capabilities and prepare for sales of the system. Quantech does
not have any commitments for any such additional financing and does not
anticipate receiving any additional significant funding from commercial lenders.


                                       11
<PAGE>

There can be no assurance that any such additional financing can be obtained on
favorable terms, if at all. Any additional equity financing will result in
dilution to Quantech stockholders.

"Going concern" statement in auditor's report may make it difficult to raise new
capital.

         Quantech has not had any significant revenues to date. As of June 30,
1999 and September 30, 1999, we had accumulated deficits of $22,727,284 and
$24,090,269, respectively. The report of the independent auditors on Quantech's
financial statements for the year ended June 30, 1999, includes an explanatory
paragraph relating to the uncertainty of Quantech's ability to continue as a
going concern, which may make it more difficult for Quantech to raise additional
capital.

Failure to complete development of the system on the current timetable and
budget would increase the amount of additional financing required and might make
it impossible for Quantech to continue operations.

         Components of the system are under various stages of development. Until
system development is completed and cleared through the FDA, there can be no
assurance that the system will be finished according to our current development
timetable and budget. Failure to timely finish on budget will require Quantech
to seek funding greater than currently anticipated and make it more difficult to
raise the additional funding. Additionally, the final price that we will need to
charge to cover the costs of the instrument and the test cartridges cannot be
determined until development is complete and FDA clearances have been obtained.
If Quantech cannot receive FDA approval and offer the system with certain
required features at a cost acceptable to potential customers, it will be
impossible for Quantech to continue operations.

Year 2000 Compliance

         We believe our internal information and non-information systems are
year 2000 compliant. Quantech is in a stage of development of its products at a
time when awareness of year 2000 issues allows it to build year 2000 compliance
into its products and operations. We believe that any existing suppliers to
Quantech who are lost due to year 2000 problems could be replaced at our current
stage of development without any serious interruption to our business or any
material adverse effect on our operations or financial condition. We are
diligently ascertaining at each step of development that our products are
compliant and are in the process of contacting key suppliers to address their
exposure to year 2000 related risks. We have, therefore, not developed any
contingency plans relating to year 2000 issues and have not budgeted any funds
for year 2000 issues. Although we believe that our systems are year 2000
compliant, unanticipated year 2000 problems may arise which, depending on the
nature and magnitude of the problem, could adversely affect our business.
Furthermore, year 2000 problems involving third parties may have a negative
impact on our suppliers and potential customers, the general economy or the
ability of businesses to receive essential services such as telecommunications
and banking. Any such occurrence could adversely affect our business.

Other Factors

         As described in Quantech's Form 10-KSB for the year ended June 30, 1999
under Cautionary Statements, there are additional factors concerning the Company
that should be considered including: uncertainty of market acceptance of
Quantech's product once introduced, inability or delay in obtaining FDA product
approval, competition, lack of marketing and manufacturing experience,
technological obsolescence, ability to maintain patent protection on the
Company's technology and not violate others' rights, effects of government
regulation on Quantech's product and its sale, ability to manufacture its
product, dependence on key personnel, exposure to the risk of product liability
and the limited market for the Company's shares.

                            ARTICLES OF AMENDMENT OF
                            ARTICLES OF INCORPORATION
                                OF QUANTECH LTD.

         The undersigned, being the Secretary of Quantech Ltd., a Minnesota

certify that the following recitals and resolutions were adopted at a duly
called special meeting of the directors, pursuant to Minnesota Statutes,
Sections 302A.135 and 302A.139.

         The Board discussed and determined that it was in the interest of
Quantech to effect the reverse split of its Capital Stock to conform its capital
structure to companies in Quantech's industry, so as to attract potential
financing and strategic partners and to position Quantech for filing on NASDAQ
when it meets such organization's listing requirements. It was determined that
the timing of the split should be coordinated with the release of information
concerning Quantech's filing with the FDA of its test for myoglobin.

         A MOTION was made by Mr. Lyons that the directors hereby adopt the
following plan of recapitalization in order to effect a 1-for-20 reverse stock
split effective on the date on which the Amendment of Articles hereinafter
adopted is filed with the Minnesota Secretary of State (the "Effective Date"):

         1.     One (1) share of Common Stock of the Company shall be issued in
                exchange for every twenty (20) shares of Common Stock
                outstanding on the Effective Date.
         2.     Fractional shares resulting on account of such reverse split
                shall be rounded down.
         3.     Promptly following the Effective Date, shareholders shall
                exchange certificates representing shares of Common Stock
                outstanding on the Effective Date for certificates representing
                the appropriate number of shares of Common Stock to reflect the
                reverse stock split.
         4.     On the Effective Date, the number of shares of the Company's
                Common Stock reserved for issuance under, or covered by, any
                outstanding option or warrant shall be decreased by twenty times
                and the per share exercise price shall be increased by such
                amount as may be necessary so that the aggregate purchase price
                of each outstanding option or warrant after adjustment is equal
                to the aggregate purchase price of such option or warrant before
                adjustment.

         FURTHER RESOLVED, that Section 3.1 of Article 3 of the Articles of
Incorporation is amended to read as follows:

                           "ARTICLE 3 - CAPITAL STOCK

                  3.1) Authorized Shares; Establishment of Classes and Series.

                  to issue shall be 12,500,000 shares, which shall have a par
                  value of $.01 per share solely for the purpose of a statute or
                  regulation imposing a tax or fee based upon the capitalization
                  of the corporation, and which shall consist of 10,000,000

<PAGE>

                  Common Shares (hereinafter referred to as "Common Stock") and
                  2,500,000 undesignated shares. Except as otherwise provided by
                  these Articles of Incorporation or in a contractual obligation
                  of the corporation, the Board of Directors of the corporation
                  is authorized to establish from the undesignated shares, by
                  resolution adopted and filed in the manner provided by law,
                  one or more classes or series of shares, to designate each
                  such class or series (which may include but is not limited to
                  designation as additional shares of Common Stock), and to fix
                  the relative rights and preferences of each such class or
                  series, which rights and preferences may be superior to those
                  of any of the shares of Common Stock."

         FURTHER RESOLVED, that any officer of the Company be and he hereby is
authorized to execute Articles of Amendment of the Articles of Incorporation of
the Company and to cause such Articles of Amendment to be filed with the
Minnesota Secretary of State.

         FURTHER RESOLVED, that the form of stock certificate reviewed this date
be and it hereby is adopted to represent the Company's Common Stock from and
after the Effective Date.

         FURTHER RESOLVED, that the officers of the Company are hereby
authorized and directed to take all such further action and execute and deliver
all such further documents and instruments as may be necessary or advisable to
effectuate such reverse stock split.

         Mr. Perkins seconded the motion and the motion was unanimously approved
by the directors.

                     Designation of Series A Preferred Stock

         WHEREAS, the corporation's current authorized capitalization consists
of 10,000,000 authorized shares of Common Stock and 2,500,000 authorized but
undesignated shares; and

         WHEREAS, the Board of Directors deems it advisable to establish an
additional class of shares from the 2,500,000 authorized but undesignated
shares;

         NOW, THEREFORE, RESOLVED, that of the 2,500,000 undesignated shares
which the corporation is authorized to issue under its Articles of
Incorporation, 2,500,000 are hereby designated as shares of Series A Preferred
Stock (the "Series A Stock"), with a par value of $0.01 per share solely for

         FURTHER RESOLVED, that the rights and preferences of the Series A Stock
shall be as follows:

         1. Dividends. In the event that the corporation declares and pays any
dividends in cash with respect to Common Stock, the holder of a share of Series

that would have been otherwise payable with respect to such share if it had been
converted into shares of Common Stock prior to the record date of such dividend.

         2. Voting. Each outstanding share of Series A Stock shall entitle its
holder to that number of votes on all matters submitted to the stockholders that
is equal to the number of shares of Common Stock into which such holder's shares
of Series A Stock are then convertible, as hereinafter provided (except that
shares of Series A Stock shall have class voting rights as provided in paragraph
3 below and as otherwise now or hereafter required by agreement or law).

         3. Additional Class Votes by Series A Stock. Without the affirmative
vote or written consent of the holders (acting together as a class) of at least
a majority of the shares of Series A Stock at the time outstanding, the
corporation shall not:

                  a. amend the Articles of Incorporation of the corporation in
         any respect, including without limitation any certificate or
         designation relating to the Series A Stock, so as to alter any existing
         provision relating to Series A Stock or the holders thereof or waive
         any of the rights granted to the holders of the Series A Stock by the
         Articles of Incorporation of the corporation; or

                  b. increase the authorized number of shares of Series A
         Stock; or

                  c. authorize or issue any shares of capital stock having
         priority or preference over, or on parity with, Series A Stock as to

<PAGE>

         dividends or distributions in the event of the liquidation, dissolution
         or winding up of the corporation, provided that such prohibition shall
         not prevent the corporation from issuing any shares which may receive
         distributions in such events on a pari passu basis prorated, in the
         event assets are insufficient to pay the original purchase price of all
         such securities, to the original purchase price of each; or

                  d. declare or pay any dividend or make any other distribution
         on any shares of capital stock of the corporation at any time created
         and issued ranking junior to Series A Stock with respect to the rights
         to the distribution of assets upon liquidation, dissolution or winding
         up of the corporation, other than distributions payable solely in
         shares of junior stock.

         4.       Liquidation.

                  a. In the event of the liquidation, dissolution or winding up
         of the corporation, whether voluntary or involuntary, the holders of
         the shares of Series A Stock shall be entitled, subject to the
         participation right of certain lenders/guarantors as provided in
         subparagraph (d) below, to receive in cash, out of the assets of the
         corporation, before any payment shall be made or any assets distributed
         to the holders of Common Stock with respect to the payment of dividends
         or upon dissolution or liquidation of the corporation, an amount equal
         to the sum of (i) $3.00 per share ("Original Purchase Price")
         (appropriately adjusted to reflect stock splits, stock dividends,
         reorganizations, consolidations and similar changes hereafter
         effected), (ii) all dividends unpaid and accumulated or accrued thereon
         to the date of such distribution, if any, and (iii) an amount equal to
         a return on investment at the rate of 10% per annum, compounded
         annually, over the period commencing on the date of original issuance
         of the Series A Stock by the corporation and ending on the date of
         distribution of assets as specified by the corporation's Board of
         Directors. If, upon any liquidation or dissolution of this corporation,
         the assets of the corporation shall be insufficient to pay such amount,
         the holders of such shares shall share pro rata in any such
         distribution in proportion to the full amounts to which they would
         otherwise be respectively entitled.

                  b. After the payment of all preferential amounts required to
         be paid pursuant to subparagraph a above, any remaining assets and
         funds of the corporation available for distribution to its stockholders
         upon the liquidation, dissolution or winding up of the corporation
         shall be distributed ratably among the holders of Common Stock.
         Thereafter, any such remaining assets and funds shall be distributed.

                  c. The merger or consolidation of the corporation into or with
         another corporation 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 such other corporation or an
         affiliate thereof (except if such merger or consolidation does not
         result in the transfer of more than 60% of the voting securities of the
         corporation), change in control of more than 60% of the voting
         securities of the corporation or the sale of all or substantially all
         the assets of the corporation, shall be deemed to be a liquidation,
         dissolution or winding up of the corporation for purposes of this
         paragraph, unless the holders of a majority of the Series A Stock then
         outstanding vote otherwise. The amount deemed distributed to the

<PAGE>

         holders of Series A Stock upon any such merger or consolidation shall
         be the cash or the value of the property, rights and/or securities
         distributed to such holders by the acquiring person, firm or other
         entity. The value of such property, rights or other securities shall be
         determined in good faith by the Board of Directors of the corporation.

                  d. The corporation and one of its current directors are
         parties to that certain Agreement dated November 5, 1998, which
         agreement provides that if the director is required to make any payment
         pursuant to that certain Guaranty and Collateral Pledge Agreement, each
         dated August 7, 1998, between such director and Norwest Bank Minnesota,
         National Association, which has provided the corporation a bank credit
         facility in the aggregate principal amount of $750,000, such director
         waives any right of recovery of such payment from the corporation
         except in the event of a liquidation by the corporation in which event
         such director shall be entitled to participate in the distribution of
         the corporation's assets in liquidation on a pro rata basis with
         holders of Series A Stock pursuant to subparagraph a above as if such
         director held an amount of Series A Stock equal to the amount of such
         director's payment under the Guaranty and Collateral Pledge Agreement
         divided by $3.00.

         5. Conversion Right. At the option of the holders thereof, the shares
of Series A Stock shall be convertible, at the office of the corporation (or at
such other office or offices, if any, as the Board of Directors may designate),
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100th of a share) of Common Stock of the corporation, at the
conversion price, determined as hereinafter provided, in effect at the time of
conversion, each share of Series A Stock being deemed to have a value of $3.00
for the purpose of such conversion. The price at which shares of Common Stock
shall be delivered upon conversion of shares of Series A Stock (herein called
the "conversion price") shall be initially $0.75 per share of Common Stock
(i.e., at an initial conversion rate of four shares of Common Stock for each
share of Series A Stock), provided, however, that such initial conversion price
shall be subject to adjustment from time to time in certain instances as
hereinafter provided. The following provisions shall govern such right of
conversion:

                  a. In order to convert shares of Series A Stock into shares of
         Common Stock of the corporation, the holder thereof shall surrender at
         any office hereinabove mentioned the certificate or certificates
         therefor, duly endorsed to the corporation or in blank, and give
         written notice to the corporation at such office that such holder
         elects to convert such shares. Shares of Series A Stock shall be deemed
         to have been converted immediately prior to the close of business on
         the day of the surrender of such shares for conversion as herein
         provided, and the person entitled to receive the shares of Common Stock
         of the corporation issuable upon such conversion shall be treated for
         all purposes as the record holder of such shares of Common Stock at
         such time. As promptly as practicable on or after the conversion date,
         the corporation shall issue and deliver or cause to be issued and
         delivered at such office a certificate or certificates for the number
         of shares of Common Stock of the corporation issuable upon such
         conversion.

                  b. The conversion price shall be subject to adjustment from
         time to time as hereinafter provided. Upon each adjustment of the

<PAGE>

         conversion price each holder of shares of Series A Stock shall
         thereafter be entitled to receive the number of shares of Common Stock
         of the corporation obtained by multiplying the conversion price in
         effect immediately prior to such adjustment by the number of shares
         issuable pursuant to conversion immediately prior to such adjustment
         and dividing the product thereof by the conversion price resulting from
         such adjustment.

                  c. If and whenever the corporation shall issue or sell any
         shares of its Common Stock for a consideration per share less than the
         conversion price in effect immediately prior to the time of such issue
         or sale of the Common Stock, then, forthwith upon such issue or sale,
         the conversion price shall be reduced to such lower price.

         No adjustment of the conversion price of the Series A Stock, however,
shall be made in an amount less than 2% of such conversion price in effect on
the date of such adjustment, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any such adjustment so carried forward, shall be
an amount equal to or greater than 4% of the conversion price of the Series A
Stock then in effect.

         The holders of at least a majority of the Series A Stock then
outstanding may elect to waive the application of the provisions of this
paragraph 5 with respect to any issue or sale by the corporation of shares of
its Common Stock for a consideration per share less than the conversion price of
the Series A Stock in effect immediately prior to the time of such issue or
sale.

         For the purposes of this paragraph 5, the following provisions (i) to
(v), inclusive, shall also be applicable:

                  (i) In the event the corporation shall grant (whether directly
         or by assumption in a merger or otherwise) any rights to subscribe for
         or to purchase, or any options for the purchase of, (a) Common Stock or
         (b) any obligations or any shares of stock of the corporation which are
         convertible into, or exchangeable for, Common Stock (any of such
         obligations or shares of stock being hereinafter called "Convertible
         Securities") whether or not such rights or 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 rights or options or upon conversion or
         exchange of such Convertible Securities (determined by dividing (x) the
         total amount, if any, received or receivable by the corporation as
         consideration for the granting of such rights or options, plus the
         minimum aggregate amount of additional consideration payable to the
         corporation upon the exercise of such rights or options, plus, in the
         case of such rights or options which relate to Convertible Securities,
         the minimum aggregate amount of additional consideration, if any,
         payable upon the issue of such Convertible Securities and upon the
         conversion or exchange thereof, by (y) the total maximum number of
         shares of Common Stock issuable upon the exercise of such rights or
         options or upon the conversion or exchange of all such Convertible
         Securities issuable upon the exercise of such rights or options) shall
         be less than the conversion price of the Series A Stock in effect
         immediately prior to the time of the granting of such rights or
         options, then the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon conversion
         or exchange of the total maximum amount of such Convertible Securities
         issuable upon the exercise of such rights or options shall (as of the

<PAGE>

         date of granting of such rights or options) be deemed to have been
         issued for such price per share. Except as provided in subparagraph d
         below, no further adjustments of the conversion price of the Series A
         Stock shall be made upon the actual issue of such Common Stock or of
         such Convertible Securities upon exercise of such rights or options or
         upon the actual issue of such Common Stock upon conversion or exchange
         of such Convertible Securities.

                  (ii) In case the corporation shall issue or sell (whether
         directly or by assumption in a merger or otherwise) any Convertible
         Securities, whether or not the rights to exchange or convert thereunder
         are immediately exercisable, and the price per share for which Common
         Stock is issuable upon such conversion or exchange (determined by
         dividing (x) 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
         (y) 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 conversion price of the Series A Stock in effect
         immediately prior to the time of such issue or at 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 (as of the date of the issue or sale of such Convertible
         Securities) be deemed to be outstanding and to have been issued for
         such price per share, provided that (a) except as provided in
         subparagraph d below, no further adjustments of the 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 rights to subscribe for or to purchase or any option to purchase
         any such Convertible Securities for which adjustments of the conversion
         price of the Series A Stock have been or are to be made pursuant to
         other provisions of this paragraph 5, no further adjustment of the
         conversion price shall be made by reason of such issue or sale.

                  (iii) In case any shares of Common Stock or Convertible
         Securities or any rights or options to purchase any such Common Stock
         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 deducting therefrom any
         expenses incurred or any underwriting commissions, discounts or
         concessions paid or allowed by the corporation in connection therewith.
         In case any shares of Common Stock or Convertible Securities or any
         rights or options to purchase any such Common Stock 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 by the Board of Directors of the corporation, without
         deducting therefrom any expenses incurred or any underwriting
         commissions, discounts or concessions paid or allowed by the
         corporation in connection therewith. In case any shares of Common Stock
         or Convertible Securities or any rights or options to purchase such

<PAGE>
         Common Stock or Convertible Securities shall be issued in connection
         with any merger or consolidation in which the corporation is the
         surviving corporation, the amount of consideration therefor shall be
         deemed to be the fair value as determined by the Board of Directors of
         the corporation of such portion of the assets and business of the
         non-surviving corporation or corporations as such Board shall determine
         to be attributable to such Common Stock, Convertible Securities, rights
         or options, as the case may be. In the event of any consolidation or
         merger of the corporation in which the corporation is not the surviving
         corporation or in the event of any sale of all or substantially all of
         the assets of the corporation for stock or other securities of any
         other corporation, the corporation shall be deemed to have issued a
         number of shares of its Common Stock for stock or securities of the
         other corporation computed on the basis of the actual exchange ratio on
         which the transaction was predicated and for a consideration equal to
         the fair market value on the date of such transaction of such stock or
         securities of the other corporation, and if any such calculation
         results in adjustment of the conversion price of the Series A Stock,
         the determination of the number of shares of Common Stock issuable upon
         conversion immediately prior to such merger, conversion or sale, for
         purposes of subparagraph d below, shall be made after giving effect to
         such adjustment of the conversion price.

                  (iv) In case the corporation shall take a record of the
         holders of its Common Stock for the purpose of entitling them (a) to
         receive a dividend or other distribution payable in Common Stock or in
         Convertible Securities, or in any rights or options to purchase any
         Common Stock or Convertible Securities, or (b) to subscribe for or
         purchase Common Stock 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 rights of subscription or purchase, as the case
         may be.

                  b. In case the corporation shall (i) declare a dividend upon
         the Common Stock payable in Common Stock (other than a dividend
         declared to effect a subdivision of the outstanding shares of Common
         Stock, as described in subparagraph e below) or Convertible Securities,
         or in any rights or options to purchase Common Stock or Convertible
         Securities, or (ii) declare any other dividend or make any other
         distribution upon the Common Stock payable otherwise than out of
         earnings or earned surplus, then thereafter each holder of shares of
         Series A Stock upon the conversion thereof will be entitled to receive
         the number of shares of Common Stock into which such shares of Series A
         Stock have been converted, and, in addition and without payment
         therefor, each dividend described in clause (i) above and each dividend
         or distribution described in clause (ii) above which such holder would
         have received by way of dividends or distributions if continuously held
         since such holder became the record holder of such shares of Series A
         Stock such holder (i) had been the record holder of the number of
         shares of Common Stock then received, and (ii) had retained all
         dividends or distributions in stock or securities (including Common
         Stock or Convertible Securities, and any rights or options to purchase
         any Common Stock or Convertible Securities) payable in respect of such
         Common Stock or in respect of any stock or securities paid as dividends
         or distributions and originating directly or indirectly from such
         Common Stock. For the purposes of the foregoing, a dividend or
         distribution other than in cash shall be considered payable out of
         earnings or earned surplus only to the extent that such earnings or
         earned surplus are charged an amount equal to the fair value of such
         dividend or distribution as determined by the Board of Directors of the
         corporation.

<PAGE>

                  c. In case the corporation shall at any time split or
         subdivide its outstanding shares of Common Stock into a greater number
         of shares, the conversion price of Series A Stock in effect immediately
         prior to such subdivision shall be proportionately reduced, and
         conversely, in case the outstanding shares of Common Stock of the
         corporation shall be combined into a smaller number of shares, the
         conversion price of Series A Stock in effect immediately prior to such
         combination shall be proportionately increased.

                  d. If (i) the purchase price provided for in any right or
         option referred to in clause (i) of subparagraph a, or (ii) the
         additional consideration, if any, payable upon the conversion or
         exchange of Convertible Securities referred to in clause (i) or clause
         (ii) of subparagraph a, or (iii) the rate at which any Convertible
         Securities referred to in clause (i) or clause (ii) of subparagraph a
         are convertible into or exchangeable for Common Stock, shall change at
         any time (other than under or by reason of provisions designed to
         protect against dilution), the conversion price of the Series A Stock
         then in effect hereunder shall forthwith be increased or decreased to
         such conversion price as would have obtained had the adjustments made
         upon the issuance of such rights, options or Convertible Securities
         been made upon the basis of (a) the issuance of the number of shares of
         Common Stock theretofore actually delivered upon the exercise of such
         options or rights or upon the conversion or exchange of such
         Convertible Securities, and the total consideration received therefor,
         and (b) the issuance at the time of such change of any such options,
         rights, or Convertible Securities then still outstanding for the
         consideration, if any, received by the corporation therefor and to be
         received on the basis of such changed price; and on the expiration of
         any such option or right or the termination of any such right to
         convert or exchange such Convertible Securities, the conversion price
         of the Series A Stock then in effect hereunder shall forthwith be
         increased to such conversion price as would have obtained had the
         adjustments made upon the issuance of such rights or options or
         Convertible Securities been made upon the basis of the issuance of the
         shares of Common Stock theretofore actually delivered (and the total
         consideration received therefor) upon the exercise of such rights or
         options or upon the conversion or exchange of such Convertible
         Securities. If the purchase price provided for in any right or option
         referred to in clause (i) of subparagraph a, or the rate at which any
         Convertible Securities referred to in clause (i) or clause (ii) of
         subparagraph a are convertible into or exchangeable for Common Stock,
         shall decrease at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible Security,
         the conversion price of the Series A Stock then in effect hereunder
         shall forthwith be decreased to such conversion price as would have
         obtained had the adjustments made upon the issuance of such right,
         option or Convertible Security been made upon the basis of the issuance
         of (and the total consideration received for) the shares of Common
         Stock delivered as aforesaid.

                  e. The corporation shall at all times insure and keep
         available out of its authorized but unissued shares of Common Stock,
         for the purpose of effecting the conversion of Series A Stock, the full
         number of shares of Common Stock then deliverable upon the conversion
         of all shares of Series A Stock then outstanding.

<PAGE>

                  f. No fractional shares shall be issued upon conversion of the
         Series A Stock, and the number of shares of Common Stock to be issued
         shall be rounded to the nearest whole share (with one-half being
         rounded to the upward). Such conversion shall be determined on the
         basis of the total number of shares of Series A Stock the holder is at
         the time converting into Common Stock and the aggregate number of
         shares of Common Stock issuable upon such conversion.

         6. Mandatory Conversion. The Series A Stock shall automatically be
converted into shares of Common Stock of the corporation, without any act by the
corporation or the holders of the Series A Stock, (i) concurrently with the
closing of an offering of the corporation's equity in which the aggregate
offering price of the securities sold for cash by the corporation in the
offering is at least $5,000,000, or such lower amount as may be approved by the
holders of at least a majority of the shares of Series A Stock then outstanding,
voting separately as a class or (ii) at such time as at least 50% of the number
of shares of Series A Stock that were outstanding as of November 30, 1998 have
been converted or redeemed. As used herein, the term "closing" shall mean the
delivery by the corporation of certificates representing the securities of the
corporation offered against delivery to the corporation of payment therefor. Any
conversion of Series A Stock occurring on the date of the closing of a financing
by the corporation satisfying the conditions set forth above shall be deemed to
be a conversion pursuant to the terms of this paragraph 6.

         Each holder of a share of Series A Stock converted pursuant to the
preceding paragraph shall be entitled to receive the full number of shares of
Common Stock into which such share of Series A Stock held by such holder could
be converted if such holder had exercised its conversion right at the time of
closing of such financing.

         7.       Redemption of Series A Stock.

                  a. If any time after November 5, 2003 the corporation receives
         a written request of the holders of not less than fifty percent (50%)
         of the then outstanding shares of Series A Stock, voting together as a
         single class and on an as-converted basis, (collectively, the
         "Initiating Holders"), the corporation shall within thirty (30) days
         after the receipt of such notice redeem all of the then outstanding
         shares of Series A Stock (or, if less, the maximum amount it may
         lawfully redeem) by paying in cash therefor an amount equal to the sum
         of the Original Purchase Price and an amount equal to a return on
         investment at the rate of 10% per annum, compounded annually, over the
         period commencing on the date of original issuance of the Series A
         Stock by the corporation and ending on the Redemption Date (defined
         below). The aggregate amounts payable with respect to Series A Stock
         are hereinafter collectively referred to as the "Redemption Price."

                  b. At least twenty (20) days prior to the date fixed for any
         redemption of any Series A Stock (the "Redemption Date"), written
         notice shall be mailed, first class postage prepaid, to each holder of
         record (at the close of business on the business day next preceding the
         day on which notice is given) of the Series A Stock to be redeemed, at
         the address last shown on the records of the corporation for such

<PAGE>

         holder or given by the holder to the corporation for the purpose of
         notice or if no such address appears or is given at the principal
         executive office of the corporation, notifying such holder of the
         redemption to be effected, specifying the number of shares to be
         redeemed from such holder, the Redemption Date, the Redemption Price,
         the place at which payment may be obtained, and the date on which such
         holder's conversion rights (as set forth in paragraph 5 above) as to
         such shares terminate, and calling upon such holder to surrender to the
         corporation, in the manner and at the place designated, the certificate
         or certificates representing the shares to be redeemed (the "Redemption
         Notice"). On or after the Redemption Date, each holder of Series A
         Stock to be redeemed shall surrender to the corporation the certificate
         or certificates representing such shares, in the manner and at the
         place designated in the Redemption Notice, and thereupon the Redemption
         Price of such shares shall be payable to the order of the person whose
         name appears on such certificate or certificates as the owner thereof
         and each surrendered certificate shall be canceled. In the event less
         than all the shares represented by any such certificate are redeemed, a
         new certificate shall be issued representing the unredeemed shares.

                  c. From and after the Redemption Date, unless there shall have
         been a default in payment of the Redemption Price, all rights of the
         holders of Series A Stock, as holders of such shares (except the right
         to receive the Redemption Price without interest upon surrender of
         their certificate or certificates) shall cease with respect to such
         shares which such holders elected to have redeemed, 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 Series A
         Stock on any Redemption Date are insufficient to redeem the total
         number of shares of Series A Stock to be redeemed on such date, those
         funds that are legally available will be used to redeem shares of
         Series A Stock such that each holder of Series A Stock receives the
         same percentage of the aggregate Series A Stock Redemption Price, as
         applicable, as such holder would otherwise receive if the corporation
         could legally redeem all of the shares put for redemption on such date.
         The shares of Series A Stock not redeemed shall remain outstanding and
         entitled to all the rights and preferences provided herein. At any time
         thereafter when additional funds of the corporation are legally
         available for the redemption of shares of Series A Stock, such funds
         will immediately be used to redeem the balance of the shares that the
         corporation has become obligated to redeem on any Redemption Date but
         that it has not redeemed.

                  d. On or prior to the Redemption Date, the corporation shall
         deposit the Redemption Price of all shares of Series A Stock designated
         for redemption in the Redemption Notice, and not yet redeemed or
         converted, with a bank or trust corporation having aggregate capital
         and surplus in excess of $100,000,000 as a trust fund for the benefit
         of the respective holders of the shares designated by holders of Series
         A Stock for redemption and not yet redeemed, with irrevocable
         instructions and authority to the bank or trust corporation to publish
         the notice of redemption thereof and pay the Redemption Price for such
         shares to their respective holders on or after the Redemption Date,
         upon receipt of notification from the corporation that such holder has
         surrendered its share certificate to the corporation pursuant to

<PAGE>

         subparagraph 7(b) above. As of the date of such deposit, the deposit
         shall constitute full payment of the shares to their holders, and from
         and after the date of the deposit the shares so called for redemption
         shall be redeemed and shall be deemed to be no longer outstanding, and
         the holders thereof shall cease to be shareholders with respect to such
         shares and shall have no rights with respect thereto except the rights
         to receive from the bank or trust corporation payment of the Redemption
         Price of the shares, without interest, upon surrender of their
         certificates therefor, and the right to convert such shares as provided
         in paragraph 5 above. Such instructions shall also provide that any
         moneys deposited by the corporation pursuant to this subparagraph 7(d)
         for the redemption of shares thereafter converted into shares of the
         corporation's Common Stock pursuant to paragraph 6 above prior to the
         Redemption Date shall be returned to the corporation forthwith upon
         such conversion. The balance of any moneys deposited by the corporation
         pursuant to this subparagraph 7(d) remaining unclaimed at the
         expiration of two (2) years following the Redemption Date shall
         thereafter be returned to the corporation upon its request expressed in
         a resolution of its Board of Directors.

         8. Status of Converted or Redeemed Stock. In the event any shares of
Series A Stock shall be converted or redeemed by the corporation, the shares so
converted or redeemed shall not be reissuable by the corporation as Series A
Stock but shall be designated authorized shares of Common Stock and available
for issuance by the corporation as Common Stock. At such time as all outstanding
shares of Series A Stock have been converted or redeemed, (i) any theretofore
authorized but unissued shares of such series shall return to the status of
undesignated shares of the corporation, (ii) this Statement of Designation shall
be deemed amended to eliminate all authorized Series A Stock and the terms and
provisions thereof, and (iii) the Board of Directors and officers of the
corporation are authorized to take such action and execute and file such
instruments as may be necessary or appropriate to effect such amendment.

               Designation of Series B Convertible Preferred Stock

         WHEREAS, the corporation's current authorized capitalization consists
of 50,000,000 authorized shares of Common Stock, 2,500,000 authorized shares of
Series A Preferred Stock and 22,500,000 authorized but undesignated shares; and

         WHEREAS, the Board of Directors deems it advisable to establish an
additional class of shares from the 22,500,000 authorized but undesignated
shares;

         NOW, THEREFORE, RESOLVED, that of the 22,500,000 undesignated shares
which the corporation is authorized to issue under its Articles of
Incorporation, 2,000,000 are hereby designated as shares of Series B Convertible
Preferred Stock (the "Series B Stock"), with a par value of $0.01 per share
solely for purposes of a statute or regulation imposing a tax or fee based upon
the capitalization of the corporation.

         FURTHER RESOLVED, that the rights and preferences of the Series B Stock
shall be as follows:

         1. Dividends. In the event that the corporation declares and pays any
dividends in cash with respect to Common Stock, the holder of a share of Series
B Stock will be entitled to receive a dividend per share equal to the dividend
that would have been otherwise payable with respect to such share if it had been
converted into shares of Common Stock prior to the record date of such dividend.

         2. Voting. Each outstanding share of Series B Stock shall entitle its
holder to that number of votes on all matters submitted to the stockholders that
is equal to the number of shares of Common Stock into which such holder's shares
of Series B Stock are then convertible, as hereinafter provided (except that
shares of Series B Stock shall have class voting rights as provided in paragraph
3 below and as otherwise now or hereafter required by agreement or law).

         3. Additional Class Votes by Series B Stock. Without the affirmative
vote or written consent of the holders (acting together as a class) of at least
a majority of the shares of Series B Stock at the time outstanding, the
corporation shall not:

                  a. amend the Articles of Incorporation of the corporation in
         any respect, including without limitation any certificate or
         designation relating to the Series B Stock, so as to alter any existing
         provision relating to Series B Stock or the holders thereof or waive
         any of the rights granted to the holders of the Series B Stock by the
         Articles of Incorporation of the corporation; or

                  b. increase the authorized number of shares of Series B
         Stock; or

                  c. authorize or issue any shares of capital stock having
         priority or preference over, or on parity with, Series B Stock as to
         dividends or distributions in the event of the liquidation, dissolution

<PAGE>

         or winding up of the corporation, provided that such prohibition shall
         not prevent the corporation from issuing any shares which may receive
         distributions in such events on a pari passu basis prorated, in the
         event assets are insufficient to pay the original purchase price of all
         such securities, to the original purchase price of each; or

                  d. declare or pay any dividend or make any other distribution
         on any shares of capital stock of the corporation at any time created
         and issued ranking junior to Series B Stock with respect to the rights
         to the distribution of assets upon liquidation, dissolution or winding
         up of the corporation, other than distributions payable solely in
         shares of junior stock.

         4.       Liquidation.

                  a. In the event of the liquidation, dissolution or winding up
         of the corporation, whether voluntary or involuntary, the holders of
         the shares of Series B Stock shall be entitled, after the payment of
         the preferential amount required to be paid to the Series A Preferred
         Stock, including the participation right of certain lenders/guarantors
         as provided in subparagraph (d) of the Designation of Series A
         Preferred Stock of this corporation, to receive in cash, out of the
         assets of the corporation, before any payment shall be made or any
         assets distributed to the holders of Common Stock with respect to the
         payment of dividends or upon dissolution or liquidation of the
         corporation, an amount equal to the sum of (i) $1.50 per share
         ("Original Purchase Price") (appropriately adjusted to reflect stock
         splits, stock dividends, reorganizations, consolidations and similar
         changes hereafter effected), and (ii) all dividends unpaid and
         accumulated or accrued thereon to the date of such distribution, if
         any. If, upon any liquidation or dissolution of this corporation, the
         assets of the corporation shall be insufficient to pay such amount, the
         holders of such shares shall share pro rata in any such distribution in
         proportion to the full amounts to which they would otherwise be
         respectively entitled.

                  b. After the payment of all preferential amounts required to
         be paid pursuant to subparagraph a above, any remaining assets and
         funds of the corporation available for distribution to its stockholders
         upon the liquidation, dissolution or winding up of the corporation
         shall be distributed ratably among the holders of Common Stock.

                  c. The merger or consolidation of the corporation into or with
         another corporation 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 such other corporation or an
         affiliate thereof (except if such merger or consolidation does not
         result in the transfer of more than 60% of the voting securities of the
         corporation), change in control of more than 60% of the voting
         securities of the corporation or the sale of all or substantially all
         the assets of the corporation, shall be deemed to be a liquidation,
         dissolution or winding up of the corporation for purposes of this
         paragraph, unless the holders of a majority of the Series B Stock then
         outstanding vote otherwise. The amount deemed distributed to the
         holders of Series B Stock upon any such merger or consolidation shall
         be the cash or the value of the property, rights and/or securities
         distributed to such holders by the acquiring person, firm or other
         entity. The value of such property, rights or other securities shall be
         determined in good faith by the Board of Directors of the corporation.

<PAGE>

         5. Conversion Right. At the option of the holders thereof, the shares
of Series B Stock shall be convertible, at the office of the corporation (or at
such other office or offices, if any, as the Board of Directors may designate),
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100th of a share) of Common Stock of the corporation, at the
conversion price, determined as hereinafter provided, in effect at the time of
conversion. The price at which shares of Common Stock shall be delivered upon
conversion of shares of Series B Stock (herein called the "conversion price")
shall be initially $1.50 per share of Common Stock (i.e., at an initial
conversion rate of one share of Common Stock for each share of Series B Stock),
provided, however, that such initial conversion price shall be subject to
adjustment from time to time in certain instances as hereinafter provided. The
following provisions shall govern such right of conversion:

                  a. In order to convert shares of Series B Stock into shares of
         Common Stock of the corporation, the holder thereof shall surrender at
         any office hereinabove mentioned the certificate or certificates
         therefor, duly endorsed to the corporation or in blank, and give
         written notice to the corporation at such office that such holder
         elects to convert such shares. Shares of Series B Stock shall be deemed
         to have been converted immediately prior to the close of business on
         the day of the surrender of such shares for conversion as herein
         provided, and the person entitled to receive the shares of Common Stock
         of the corporation issuable upon such conversion shall be treated for
         all purposes as the record holder of such shares of Common Stock at
         such time. As promptly as practicable on or after the conversion date,
         the corporation shall issue and deliver or cause to be issued and
         delivered at such office a certificate or certificates for the number
         of shares of Common Stock of the corporation issuable upon such
         conversion.

                  b. The conversion price shall be subject to adjustment from
         time to time as hereinafter provided. Upon each adjustment of the
         conversion price each holder of shares of Series B Stock shall
         thereafter be entitled to receive the number of shares of Common Stock
         of the corporation obtained by multiplying the conversion price in
         effect immediately prior to such adjustment by the number of shares
         issuable pursuant to conversion immediately prior to such adjustment
         and dividing the product thereof by the conversion price resulting from
         such adjustment.

                  c. If in the next sale of securities by this corporation after
         the adoption of this Designation, excluding any sale pursuant to
         options, warrants or conversion rights outstanding as the date of
         adoption of this Designation, the price per share of Common Stock sold
         is less than $1.875, or if the security sold is not Common Stock but is
         convertible into or exercisable to purchase Common Stock at a
         conversion or exercise price of less than $1.875 per share, then the
         conversion price shall be reduced an amount equal to 80% of the price
         per share at which such security is sold, convertible or exercisable.

         No adjustment of the conversion price of the Series B Stock, however,
shall be made in an amount less than 2% of such conversion price in effect on
the date of such adjustment, but any such lesser adjustment shall be carried

<PAGE>

forward and shall be made at the time and together with the next subsequent
adjustment which, together with any such adjustment so carried forward, shall be
an amount equal to or greater than 4% of the conversion price of the Series B
Stock then in effect.

         The holders of at least a majority of the Series B Stock then
outstanding may elect to waive the application of the provisions of this
paragraph 5 with respect to any issue or sale by the corporation of shares of
its Common Stock for a consideration per share less than the conversion price of
the Series B Stock in effect immediately prior to the time of such issue or
sale.

         For the purposes of this paragraph 5, the following provisions (i) to
(v), inclusive, shall also be applicable:

                  (i) In the event the corporation shall grant (whether directly
         or by assumption in a merger or otherwise) any rights to subscribe for
         or to purchase, or any options for the purchase of, (a) Common Stock or
         (b) any obligations or any shares of stock of the corporation which are
         convertible into, or exchangeable for, Common Stock (any of such
         obligations or shares of stock being hereinafter called "Convertible
         Securities") whether or not such rights or 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 rights or options or upon conversion or
         exchange of such Convertible Securities (determined by dividing (x) the
         total amount, if any, received or receivable by the corporation as
         consideration for the granting of such rights or options, plus the
         minimum aggregate amount of additional consideration payable to the
         corporation upon the exercise of such rights or options, plus, in the
         case of such rights or options which relate to Convertible Securities,
         the minimum aggregate amount of additional consideration, if any,
         payable upon the issue of such Convertible Securities and upon the
         conversion or exchange thereof, by (y) the total maximum number of
         shares of Common Stock issuable upon the exercise of such rights or
         options or upon the conversion or exchange of all such Convertible
         Securities issuable upon the exercise of such rights or options) shall
         be less than the conversion price of the Series B Stock in effect
         immediately prior to the time of the granting of such rights or
         options, then the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon conversion
         or exchange of the total maximum amount of such Convertible Securities
         issuable upon the exercise of such rights or options shall (as of the
         date of granting of such rights or options) be deemed to have been
         issued for such price per share. Except as provided in subparagraph d
         below, no further adjustments of the conversion price of the Series B
         Stock shall be made upon the actual issue of such Common Stock or of
         such Convertible Securities upon exercise of such rights or options or
         upon the actual issue of such Common Stock upon conversion or exchange
         of such Convertible Securities.

                  (ii) In case the corporation shall issue or sell (whether
         directly or by assumption in a merger or otherwise) any Convertible
         Securities, whether or not the rights to exchange or convert thereunder
         are immediately exercisable, and the price per share for which Common
         Stock is issuable upon such conversion or exchange (determined by
         dividing (x) the total amount received or receivable by the corporation
         as consideration for the issue or sale of such Convertible Securities,

<PAGE>

         plus the minimum aggregate amount of additional consideration, if any,
         payable to the corporation upon the conversion or exchange thereof, by
         (y) 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 conversion price of the Series B Stock in effect
         immediately prior to the time of such issue or at 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 (as of the date of the issue or sale of such Convertible
         Securities) be deemed to be outstanding and to have been issued for
         such price per share, provided that (a) except as provided in
         subparagraph d below, no further adjustments of the 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 rights to subscribe for or to purchase or any option to purchase
         any such Convertible Securities for which adjustments of the conversion
         price of the Series B Stock have been or are to be made pursuant to
         other provisions of this paragraph 5, no further adjustment of the
         conversion price shall be made by reason of such issue or sale.

                  (iii) In case any shares of Common Stock or Convertible
         Securities or any rights or options to purchase any such Common Stock
         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 deducting therefrom any
         expenses incurred or any underwriting commissions, discounts or
         concessions paid or allowed by the corporation in connection therewith.
         In case any shares of Common Stock or Convertible Securities or any
         rights or options to purchase any such Common Stock 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 by the Board of Directors of the corporation, without
         deducting therefrom any expenses incurred or any underwriting
         commissions, discounts or concessions paid or allowed by the
         corporation in connection therewith. In case any shares of Common Stock
         or Convertible Securities or any rights or options to purchase such
         Common Stock or Convertible Securities shall be issued in connection
         with any merger or consolidation in which the corporation is the
         surviving corporation, the amount of consideration therefor shall be
         deemed to be the fair value as determined by the Board of Directors of
         the corporation of such portion of the assets and business of the
         non-surviving corporation or corporations as such Board shall determine
         to be attributable to such Common Stock, Convertible Securities, rights
         or options, as the case may be. In the event of any consolidation or
         merger of the corporation in which the corporation is not the surviving
         corporation or in the event of any sale of all or substantially all of
         the assets of the corporation for stock or other securities of any
         other corporation, the corporation shall be deemed to have issued a
         number of shares of its Common Stock for stock or securities of the
         other corporation computed on the basis of the actual exchange ratio on
         which the transaction was predicated and for a consideration equal to
         the fair market value on the date of such transaction of such stock or
         securities of the other corporation, and if any such calculation
         results in adjustment of the conversion price of the Series B Stock,
         the determination of the number of shares of Common Stock issuable upon
         conversion immediately prior to such merger, conversion or sale, for
         purposes of subparagraph d below, shall be made after giving effect to
         such adjustment of the conversion price.

<PAGE>

                  (iv) In case the corporation shall take a record of the
         holders of its Common Stock for the purpose of entitling them (a) to
         receive a dividend or other distribution payable in Common Stock or in
         Convertible Securities, or in any rights or options to purchase any
         Common Stock or Convertible Securities, or (b) to subscribe for or
         purchase Common Stock 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 rights of subscription or purchase, as the case
         may be.

                  b. In case the corporation shall (i) declare a dividend upon
         the Common Stock payable in Common Stock (other than a dividend
         declared to effect a subdivision of the outstanding shares of Common
         Stock, as described in subparagraph e below) or Convertible Securities,
         or in any rights or options to purchase Common Stock or Convertible
         Securities, or (ii) declare any other dividend or make any other
         distribution upon the Common Stock payable otherwise than out of
         earnings or earned surplus, then thereafter each holder of shares of
         Series B Stock upon the conversion thereof will be entitled to receive
         the number of shares of Common Stock into which such shares of Series B
         Stock have been converted, and, in addition and without payment
         therefor, each dividend described in clause (i) above and each dividend
         or distribution described in clause (ii) above which such holder would
         have received by way of dividends or distributions if continuously held
         since such holder became the record holder of such shares of Series B
         Stock such holder (i) had been the record holder of the number of
         shares of Common Stock then received, and (ii) had retained all
         dividends or distributions in stock or securities (including Common
         Stock or Convertible Securities, and any rights or options to purchase
         any Common Stock or Convertible Securities) payable in respect of such
         Common Stock or in respect of any stock or securities paid as dividends
         or distributions and originating directly or indirectly from such
         Common Stock. For the purposes of the foregoing, a dividend or
         distribution other than in cash shall be considered payable out of
         earnings or earned surplus only to the extent that such earnings or
         earned surplus are charged an amount equal to the fair value of such
         dividend or distribution as determined by the Board of Directors of the
         corporation.

                  c. In case the corporation shall at any time split or
         subdivide its outstanding shares of Common Stock into a greater number
         of shares, the conversion price of Series B Stock in effect immediately
         prior to such subdivision shall be proportionately reduced, and
         conversely, in case the outstanding shares of Common Stock of the
         corporation shall be combined into a smaller number of shares, the
         conversion price of Series B Stock in effect immediately prior to such
         combination shall be proportionately increased.

                  d. If (i) the purchase price provided for in any right or
         option referred to in clause (i) of subparagraph a, or (ii) the
         additional consideration, if any, payable upon the conversion or
         exchange of Convertible Securities referred to in clause (i) or clause
         (ii) of subparagraph a, or (iii) the rate at which any Convertible
         Securities referred to in clause (i) or clause (ii) of subparagraph a
         are convertible into or exchangeable for Common Stock, shall change at
         any time (other than under or by reason of provisions designed to

<PAGE>

         protect against dilution), the conversion price of the Series B Stock
         then in effect hereunder shall forthwith be increased or decreased to
         such conversion price as would have obtained had the adjustments made
         upon the issuance of such rights, options or Convertible Securities
         been made upon the basis of (a) the issuance of the number of shares of
         Common Stock theretofore actually delivered upon the exercise of such
         options or rights or upon the conversion or exchange of such
         Convertible Securities, and the total consideration received therefor,
         and (b) the issuance at the time of such change of any such options,
         rights, or Convertible Securities then still outstanding for the
         consideration, if any, received by the corporation therefor and to be
         received on the basis of such changed price; and on the expiration of
         any such option or right or the termination of any such right to
         convert or exchange such Convertible Securities, the conversion price
         of the Series B Stock then in effect hereunder shall forthwith be
         increased to such conversion price as would have obtained had the
         adjustments made upon the issuance of such rights or options or
         Convertible Securities been made upon the basis of the issuance of the
         shares of Common Stock theretofore actually delivered (and the total
         consideration received therefor) upon the exercise of such rights or
         options or upon the conversion or exchange of such Convertible
         Securities. If the purchase price provided for in any right or option
         referred to in clause (i) of subparagraph a, or the rate at which any
         Convertible Securities referred to in clause (i) or clause (ii) of
         subparagraph a are convertible into or exchangeable for Common Stock,
         shall decrease at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible Security,
         the conversion price of the Series B Stock then in effect hereunder
         shall forthwith be decreased to such conversion price as would have
         obtained had the adjustments made upon the issuance of such right,
         option or Convertible Security been made upon the basis of the issuance
         of (and the total consideration received for) the shares of Common
         Stock delivered as aforesaid.

                  e. The corporation shall at all times insure and keep
         available out of its authorized but unissued shares of Common Stock,
         for the purpose of effecting the conversion of Series B Stock, the full
         number of shares of Common Stock then deliverable upon the conversion
         of all shares of Series B Stock then outstanding.

                  f. No fractional shares shall be issued upon conversion of the
         Series B Stock, and the number of shares of Common Stock to be issued
         shall be rounded to the nearest whole share (with one-half being
         rounded to the upward). Such conversion shall be determined on the
         basis of the total number of shares of Series B Stock the holder is at
         the time converting into Common Stock and the aggregate number of
         shares of Common Stock issuable upon such conversion.

         6. Mandatory Conversion. The Series B Stock shall automatically be
converted into shares of Common Stock of the corporation, without any act by the
corporation or the holders of the Series B Stock, (i) concurrently with the
closing of an offering of the corporation's equity in which the aggregate
offering price of the securities sold for cash by the corporation in the
offering is at least $5,000,000, or (ii) at such time as at least 50% of the
number of shares of Series B Stock have been converted into Common Stock. As
used herein, the term "closing" shall mean the delivery by the corporation of
certificates representing the securities of the corporation offered against
delivery to the corporation of payment therefor. Any conversion of Series B

<PAGE>

Stock occurring on the date of the closing of a financing by the corporation
satisfying the conditions set forth above shall be deemed to be a conversion
pursuant to the terms of this paragraph 6.

         Each holder of a share of Series B Stock converted pursuant to the
preceding paragraph shall be entitled to receive the full number of shares of
Common Stock into which such share of Series B Stock held by such holder could
be converted if such holder had exercised its conversion right at the time of
closing of such financing.

         7. Status of Converted Stock. In the event any shares of Series B Stock
shall be converted by the corporation, the shares so converted shall not be
reissuable by the corporation as Series B Stock but shall be designated
authorized shares of Common Stock and available for issuance by the corporation
as Common Stock. At such time as all outstanding shares of Series B Stock have
been converted, (i) any theretofore authorized but unissued shares of such
series shall return to the status of undesignated shares of the corporation,
(ii) this Statement of Designation shall be deemed amended to eliminate all
authorized Series B Stock and the terms and provisions thereof, and (iii) the
Board of Directors and officers of the corporation are authorized to take such
action and execute and file such instruments as may be necessary or appropriate
to effect such amendment.

                            STATEMENT OF DESIGNATION
                                       OF
                      SERIES B CONVERTIBLE PREFERRED STOCK

         WHEREAS, the corporation's current authorized capitalization consists
of 50,000,000 authorized shares of Common Stock, 2,500,000 authorized shares of
Series A Preferred Stock and 22,500,000 authorized but undesignated shares; and

         WHEREAS, the Board of Directors deems it advisable to establish an
additional class of shares from the 22,500,000 authorized but undesignated
shares;

         NOW, THEREFORE, RESOLVED, that of the 22,500,000 undesignated shares
which the corporation is authorized to issue under its Articles of
Incorporation, 3,000,000 are hereby designated as shares of Series B Convertible
Preferred Stock (the "Series B Stock"), with a par value of $0.01 per share
solely for purposes of a statute or regulation imposing a tax or fee based upon
the capitalization of the corporation.

         FURTHER RESOLVED, that the rights and preferences of the Series B Stock
shall be as follows:

         1. Dividends. In the event that the corporation declares and pays any
dividends in cash with respect to Common Stock, the holder of a share of Series
B Stock will be entitled to receive a dividend per share equal to the dividend
that would have been otherwise payable with respect to such share if it had been
converted into shares of Common Stock prior to the record date of such dividend.

         2. Voting. Each outstanding share of Series B Stock shall entitle its
holder to that number of votes on all matters submitted to the stockholders that
is equal to the number of shares of Common Stock into which such holder's shares
of Series B Stock are then convertible, as hereinafter provided (except that
shares of Series B Stock shall have class voting rights as provided in paragraph
3 below and as otherwise now or hereafter required by agreement or law).

         3. Additional Class Votes by Series B Stock. Without the affirmative
vote or written consent of the holders (acting together as a class) of at least
a majority of the shares of Series B Stock at the time outstanding, the
corporation shall not:

                  a. amend the Articles of Incorporation of the corporation in
         any respect, including without limitation any certificate or
         designation relating to the Series B Stock, so as to alter any existing
         provision relating to Series B Stock or the holders thereof or waive
         any of the rights granted to the holders of the Series B Stock by the
         Articles of Incorporation of the corporation; or


<PAGE>

                  b. increase the authorized number of shares of Series B
         Stock; or

                  c. authorize or issue any shares of capital stock having
         priority or preference over, or on parity with, Series B Stock as to
         dividends or distributions in the event of the liquidation, dissolution
         or winding up of the corporation, provided that such prohibition shall
         not prevent the corporation from issuing any shares which may receive
         distributions in such events on a pari passu basis prorated, in the
         event assets are insufficient to pay the original purchase price of all
         such securities, to the original purchase price of each; or

                  d. declare or pay any dividend or make any other distribution
         on any shares of capital stock of the corporation at any time created
         and issued ranking junior to Series B Stock with respect to the rights
         to the distribution of assets upon liquidation, dissolution or winding
         up of the corporation, other than distributions payable solely in
         shares of junior stock.

         4.       Liquidation.

                  a. In the event of the liquidation, dissolution or winding up
         of the corporation, whether voluntary or involuntary, the holders of
         the shares of Series B Stock shall be entitled, after the payment of
         the preferential amount required to be paid to the Series A Preferred
         Stock, including the participation right of certain lenders/guarantors
         as provided in subparagraph (d) of the Designation of Series A
         Preferred Stock of this corporation, to receive in cash, out of the
         assets of the corporation, before any payment shall be made or any
         assets distributed to the holders of Common Stock with respect to the
         payment of dividends or upon dissolution or liquidation of the
         corporation, an amount equal to the sum of (i) $1.00 per share
         ("Original Purchase Price") (appropriately adjusted to reflect stock
         splits, stock dividends, reorganizations, consolidations and similar
         changes hereafter effected), and (ii) all dividends unpaid and
         accumulated or accrued thereon to the date of such distribution, if
         any. If, upon any liquidation or dissolution of this corporation, the
         assets of the corporation shall be insufficient to pay such amount, the
         holders of such shares shall share pro rata in any such distribution in
         proportion to the full amounts to which they would otherwise be
         respectively entitled.

                  b. After the payment of all preferential amounts required to
         be paid pursuant to subparagraph a above, any remaining assets and
         funds of the corporation available for distribution to its stockholders
         upon the liquidation, dissolution or winding up of the corporation
         shall be distributed ratably among the holders of Common Stock.

                  c. The merger or consolidation of the corporation into or with
         another corporation 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 such other corporation or an
         affiliate thereof (except if such merger or consolidation does not
         result in the transfer of more than 60% of the voting securities of the
         corporation), change in control of more than 60% of the voting

<PAGE>

         securities of the corporation or the sale of all or substantially all
         the assets of the corporation, shall be deemed to be a liquidation,
         dissolution or winding up of the corporation for purposes of this
         paragraph, unless the holders of a majority of the Series B Stock then
         outstanding vote otherwise. The amount deemed distributed to the
         holders of Series B Stock upon any such merger or consolidation shall
         be the cash or the value of the property, rights and/or securities
         distributed to such holders by the acquiring person, firm or other
         entity. The value of such property, rights or other securities shall be
         determined in good faith by the Board of Directors of the corporation.

         5. Conversion Right. At the option of the holders thereof, the shares
of Series B Stock shall be convertible, at the office of the corporation (or at
such other office or offices, if any, as the Board of Directors may designate),
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100th of a share) of Common Stock of the corporation, at the
conversion price, determined as hereinafter provided, in effect at the time of
conversion. The price at which shares of Common Stock shall be delivered upon
conversion of shares of Series B Stock (herein called the "conversion price")
shall be initially $1.00 per share of Common Stock (i.e., at an initial
conversion rate of one share of Common Stock for each share of Series B Stock),
provided, however, that such initial conversion price shall be subject to
adjustment from time to time in certain instances as hereinafter provided. The
following provisions shall govern such right of conversion:

                  a. In order to convert shares of Series B Stock into shares of
         Common Stock of the corporation, the holder thereof shall surrender at
         any office hereinabove mentioned the certificate or certificates
         therefor, duly endorsed to the corporation or in blank, and give
         written notice to the corporation at such office that such holder
         elects to convert such shares. Shares of Series B Stock shall be deemed
         to have been converted immediately prior to the close of business on
         the day of the surrender of such shares for conversion as herein
         provided, and the person entitled to receive the shares of Common Stock
         of the corporation issuable upon such conversion shall be treated for
         all purposes as the record holder of such shares of Common Stock at
         such time. As promptly as practicable on or after the conversion date,
         the corporation shall issue and deliver or cause to be issued and
         delivered at such office a certificate or certificates for the number
         of shares of Common Stock of the corporation issuable upon such
         conversion.

                  b. The conversion price shall be subject to adjustment from
         time to time as hereinafter provided. Upon each adjustment of the
         conversion price each holder of shares of Series B Stock shall
         thereafter be entitled to receive the number of shares of Common Stock
         of the corporation obtained by multiplying the conversion price in
         effect immediately prior to such adjustment by the number of shares
         issuable pursuant to conversion immediately prior to such adjustment
         and dividing the product thereof by the conversion price resulting from
         such adjustment.

                  c. If in the next sale of securities by this corporation after
         the adoption of this Designation, excluding any sale pursuant to
         options, warrants or conversion rights outstanding as of the date of
         adoption of this Designation, the price per share of Common Stock sold
         is less than $1.00, or if the security sold is not Common Stock but is
         convertible into or exercisable to purchase Common Stock at a
         conversion or exercise price of less than $1.00 per share, then the

<PAGE>

         conversion price shall be reduced to an amount equal to the price per
         share at which such security is sold, convertible or exercisable.

         No adjustment of the conversion price of the Series B Stock, however,
shall be made in an amount less than 2% of such conversion price in effect on
the date of such adjustment, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any such adjustment so carried forward, shall be
an amount equal to or greater than 4% of the conversion price of the Series B
Stock then in effect.

         The holders of at least a majority of the Series B Stock then
outstanding may elect to waive the application of the provisions of this
paragraph 5 with respect to any issue or sale by the corporation of shares of
its Common Stock for a consideration per share less than the conversion price of
the Series B Stock in effect immediately prior to the time of such issue or
sale.

         For the purposes of this paragraph 5, the following provisions (i) to
(v), inclusive, shall also be applicable:

                  (i) In the event the corporation shall grant (whether directly
         or by assumption in a merger or otherwise) any rights to subscribe for
         or to purchase, or any options for the purchase of, (a) Common Stock or
         (b) any obligations or any shares of stock of the corporation which are
         convertible into, or exchangeable for, Common Stock (any of such
         obligations or shares of stock being hereinafter called "Convertible
         Securities") whether or not such rights or 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 rights or options or upon conversion or
         exchange of such Convertible Securities (determined by dividing (x) the
         total amount, if any, received or receivable by the corporation as
         consideration for the granting of such rights or options, plus the
         minimum aggregate amount of additional consideration payable to the
         corporation upon the exercise of such rights or options, plus, in the
         case of such rights or options which relate to Convertible Securities,
         the minimum aggregate amount of additional consideration, if any,
         payable upon the issue of such Convertible Securities and upon the
         conversion or exchange thereof, by (y) the total maximum number of
         shares of Common Stock issuable upon the exercise of such rights or
         options or upon the conversion or exchange of all such Convertible
         Securities issuable upon the exercise of such rights or options) shall
         be less than the conversion price of the Series B Stock in effect
         immediately prior to the time of the granting of such rights or
         options, then the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon conversion
         or exchange of the total maximum amount of such Convertible Securities
         issuable upon the exercise of such rights or options shall (as of the
         date of granting of such rights or options) be deemed to have been
         issued for such price per share. Except as provided in subparagraph (d)
         below, no further adjustments of the conversion price of the Series B
         Stock shall be made upon the actual issue of such Common Stock or of
         such Convertible Securities upon exercise of such rights or options or
         upon the actual issue of such Common Stock upon conversion or exchange
         of such Convertible Securities.

<PAGE>

                  (ii) In case the corporation shall issue or sell (whether
         directly or by assumption in a merger or otherwise) any Convertible
         Securities, whether or not the rights to exchange or convert thereunder
         are immediately exercisable, and the price per share for which Common
         Stock is issuable upon such conversion or exchange (determined by
         dividing (x) 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
         (y) 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 conversion price of the Series B Stock in effect
         immediately prior to the time of such issue or at 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 (as of the date of the issue or sale of such Convertible
         Securities) be deemed to be outstanding and to have been issued for
         such price per share, provided that (a) except as provided in
         subparagraph d below, no further adjustments of the 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 rights to subscribe for or to purchase or any option to purchase
         any such Convertible Securities for which adjustments of the conversion
         price of the Series B Stock have been or are to be made pursuant to
         other provisions of this paragraph 5, no further adjustment of the
         conversion price shall be made by reason of such issue or sale.

                  (iii) In case any shares of Common Stock or Convertible
         Securities or any rights or options to purchase any such Common Stock
         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 deducting therefrom any
         expenses incurred or any underwriting commissions, discounts or
         concessions paid or allowed by the corporation in connection therewith.
         In case any shares of Common Stock or Convertible Securities or any
         rights or options to purchase any such Common Stock 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 by the Board of Directors of the corporation, without
         deducting therefrom any expenses incurred or any underwriting
         commissions, discounts or concessions paid or allowed by the
         corporation in connection therewith. In case any shares of Common Stock
         or Convertible Securities or any rights or options to purchase such
         Common Stock or Convertible Securities shall be issued in connection
         with any merger or consolidation in which the corporation is the
         surviving corporation, the amount of consideration therefor shall be
         deemed to be the fair value as determined by the Board of Directors of
         the corporation of such portion of the assets and business of the
         non-surviving corporation or corporations as such Board shall determine
         to be attributable to such Common Stock, Convertible Securities, rights
         or options, as the case may be. In the event of any consolidation or
         merger of the corporation in which the corporation is not the surviving
         corporation or in the event of any sale of all or substantially all of
         the assets of the corporation for stock or other securities of any
         other corporation, the corporation shall be deemed to have issued a
         number of shares of its Common Stock for stock or securities of the
         other corporation computed on the basis of the actual exchange ratio on
         which the transaction was predicated and for a consideration equal to

<PAGE>
         the fair market value on the date of such transaction of such stock or
         securities of the other corporation, and if any such calculation
         results in adjustment of the conversion price of the Series B Stock,
         the determination of the number of shares of Common Stock issuable upon
         conversion immediately prior to such merger, conversion or sale, for
         purposes of subparagraph d below, shall be made after giving effect to
         such adjustment of the conversion price.

                  (iv) In case the corporation shall take a record of the
         holders of its Common Stock for the purpose of entitling them (a) to
         receive a dividend or other distribution payable in Common Stock or in
         Convertible Securities, or in any rights or options to purchase any
         Common Stock or Convertible Securities, or (b) to subscribe for or
         purchase Common Stock 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 rights of subscription or purchase, as the case
         may be.

                  b. In case the corporation shall (i) declare a dividend upon
         the Common Stock payable in Common Stock (other than a dividend
         declared to effect a subdivision of the outstanding shares of Common
         Stock, as described in subparagraph e below) or Convertible Securities,
         or in any rights or options to purchase Common Stock or Convertible
         Securities, or (ii) declare any other dividend or make any other
         distribution upon the Common Stock payable otherwise than out of
         earnings or earned surplus, then thereafter each holder of shares of
         Series B Stock upon the conversion thereof will be entitled to receive
         the number of shares of Common Stock into which such shares of Series B
         Stock have been converted, and, in addition and without payment
         therefor, each dividend described in clause (i) above and each dividend
         or distribution described in clause (ii) above which such holder would
         have received by way of dividends or distributions if continuously held
         since such holder became the record holder of such shares of Series B
         Stock such holder (i) had been the record holder of the number of
         shares of Common Stock then received, and (ii) had retained all
         dividends or distributions in stock or securities (including Common
         Stock or Convertible Securities, and any rights or options to purchase
         any Common Stock or Convertible Securities) payable in respect of such
         Common Stock or in respect of any stock or securities paid as dividends
         or distributions and originating directly or indirectly from such
         Common Stock. For the purposes of the foregoing, a dividend or
         distribution other than in cash shall be considered payable out of
         earnings or earned surplus only to the extent that such earnings or
         earned surplus are charged an amount equal to the fair value of such
         dividend or distribution as determined by the Board of Directors of the
         corporation.

                  c. In case the corporation shall at any time split or
         subdivide its outstanding shares of Common Stock into a greater number
         of shares, the conversion price of Series B Stock in effect immediately
         prior to such subdivision shall be proportionately reduced, and
         conversely, in case the outstanding shares of Common Stock of the
         corporation shall be combined into a smaller number of shares, the
         conversion price of Series B Stock in effect immediately prior to such
         combination shall be proportionately increased.

<PAGE>

                  d. If (i) the purchase price provided for in any right or
         option referred to in clause (i) of subparagraph a, or (ii) the
         additional consideration, if any, payable upon the conversion or
         exchange of Convertible Securities referred to in clause (i) or clause
         (ii) of subparagraph a, or (iii) the rate at which any Convertible
         Securities referred to in clause (i) or clause (ii) of subparagraph a
         are convertible into or exchangeable for Common Stock, shall change at
         any time (other than under or by reason of provisions designed to
         protect against dilution), the conversion price of the Series B Stock
         then in effect hereunder shall forthwith be increased or decreased to
         such conversion price as would have obtained had the adjustments made
         upon the issuance of such rights, options or Convertible Securities
         been made upon the basis of (a) the issuance of the number of shares of
         Common Stock theretofore actually delivered upon the exercise of such
         options or rights or upon the conversion or exchange of such
         Convertible Securities, and the total consideration received therefor,
         and (b) the issuance at the time of such change of any such options,
         rights, or Convertible Securities then still outstanding for the
         consideration, if any, received by the corporation therefor and to be
         received on the basis of such changed price; and on the expiration of
         any such option or right or the termination of any such right to
         convert or exchange such Convertible Securities, the conversion price
         of the Series B Stock then in effect hereunder shall forthwith be
         increased to such conversion price as would have obtained had the
         adjustments made upon the issuance of such rights or options or
         Convertible Securities been made upon the basis of the issuance of the
         shares of Common Stock theretofore actually delivered (and the total
         consideration received therefor) upon the exercise of such rights or
         options or upon the conversion or exchange of such Convertible
         Securities. If the purchase price provided for in any right or option
         referred to in clause (i) of subparagraph a, or the rate at which any
         Convertible Securities referred to in clause (i) or clause (ii) of
         subparagraph a are convertible into or exchangeable for Common Stock,
         shall decrease at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible Security,
         the conversion price of the Series B Stock then in effect hereunder
         shall forthwith be decreased to such conversion price as would have
         obtained had the adjustments made upon the issuance of such right,
         option or Convertible Security been made upon the basis of the issuance
         of (and the total consideration received for) the shares of Common
         Stock delivered as aforesaid.

                  e. The corporation shall at all times insure and keep
         available out of its authorized but unissued shares of Common Stock,
         for the purpose of effecting the conversion of Series B Stock, the full
         number of shares of Common Stock then deliverable upon the conversion
         of all shares of Series B Stock then outstanding.

                  f. No fractional shares shall be issued upon conversion of the
         Series B Stock, and the number of shares of Common Stock to be issued
         shall be rounded to the nearest whole share (with one-half being
         rounded to the upward). Such conversion shall be determined on the
         basis of the total number of shares of Series B Stock the holder is at
         the time converting into Common Stock and the aggregate number of
         shares of Common Stock issuable upon such conversion.

<PAGE>

         6. Mandatory Conversion. The Series B Stock shall automatically be
converted into shares of Common Stock of the corporation, without any act by the
corporation or the holders of the Series B Stock, (i) concurrently with the
closing of an offering of the corporation's equity in which the aggregate
offering price of the securities sold for cash by the corporation in the
offering is at least $5,000,000, or (ii) at such time as at least 50% of the
number of shares of Series B Stock have been converted into Common Stock. As
used herein, the term "closing" shall mean the delivery by the corporation of
certificates representing the securities of the corporation offered against
delivery to the corporation of payment therefor. Any conversion of Series B
Stock occurring on the date of the closing of a financing by the corporation
satisfying the conditions set forth above shall be deemed to be a conversion
pursuant to the terms of this paragraph 6.

         Each holder of a share of Series B Stock converted pursuant to the
preceding paragraph shall be entitled to receive the full number of shares of
Common Stock into which such share of Series B Stock held by such holder could
be converted if such holder had exercised its conversion right at the time of
closing of such financing.

         7. Status of Converted Stock. In the event any shares of Series B Stock
shall be converted by the corporation, the shares so converted shall not be
reissuable by the corporation as Series B Stock but shall be designated
authorized shares of Common Stock and available for issuance by the corporation
as Common Stock. At such time as all outstanding shares of Series B Stock have
been converted, (i) any theretofore authorized but unissued shares of such
series shall return to the status of undesignated shares of the corporation,
(ii) this Statement of Designation shall be deemed amended to eliminate all
authorized Series B Stock and the terms and provisions thereof, and (iii) the
Board of Directors and officers of the corporation are authorized to take such
action and execute and file such instruments as may be necessary or appropriate
to effect such amendment.
