                      GOVERNMENT TECHNOLOGY SERVICES, INC.

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

               Pursuant to Section 151 of the General Corporation
                          Law of the State of Delaware

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


         GOVERNMENT TECHNOLOGY SERVICES, INC., a Delaware corporation (the
"Corporation"), certifies that, pursuant to the authority contained in Article
FOURTH of its Amended Certificate of Incorporation, and in accordance with the
provisions of Section 151 of the General Corporation Law of the State of
Delaware, the Corporation's board of directors (the "Board") duly adopted the
following resolution creating a series of preferred stock of the Corporation
designated as "Series C 8% Cumulative Redeemable Convertible Preferred Stock."

         RESOLVED, that pursuant to the authority vested in the Board in
accordance with the provisions of the Corporation's Amended Certificate of
Incorporation, a series of preferred stock of the Corporation designated as
"Series C 8% Redeemable Convertible Cumulative Preferred Stock" be, and hereby
is, created, and that the designation and amount thereof and the voting powers,
preferences and relative, participating, optional and the special rights of the
shares of such series, and the qualifications, limitations or restrictions
thereof, are as follows:

         1. Designation and Amount. The series of preferred stock established
hereby shall be designated the "Series C 8% Cumulative Redeemable Convertible
Preferred Stock," with a par value of $0.25 per share (the "Series C Preferred
Stock"), and the authorized number of shares of Series C Preferred Stock shall
be 100,000.

         2. Rank. The Series C Preferred Stock shall, with respect to dividend
distributions and distributions upon the voluntary or involuntary liquidation,
dissolution and winding-up of the Corporation, rank (i) senior to all classes
of Common Stock and each other class of Capital Stock of the Corporation or
series of preferred stock of the Corporation hereafter created which is not
Senior Stock or Parity Stock ("Junior Stock"), (ii) pari passu with any Parity
Stock and (iii) junior to any Senior Stock. There is no Senior Stock or Parity
Stock outstanding on the date hereof and such stock may not be authorized or
issued except in accordance with Section 7(b).





                                       1
   2
         3. Dividends. (a) Dividend Rate.  Subject to the provisions of Section
3(c), commencing on the Dividend Commencement Date, the Holders shall be
entitled to receive, when, as and if declared by the Board, but only out of
funds legally available therefor, distributions in the form of cash dividends
on each share of Series C Preferred Stock at a rate of 8% per annum of the
Liquidation Preference and no more. All dividends (i) shall accrue and be
cumulative, whether or not declared by the Board, on a daily basis from (1) the
Dividend Commencement Date with respect to Initial Series C Preferred Stock and
(2) the Original Issuance Date with respect to Series C Preferred Stock the
Original Issuance Date of which is after the Initial Issue Date, and (ii) when,
as and if declared by the Board, shall be payable annually in arrears on each
Dividend Payment Date commencing with the first Dividend Payment Date after (1)
the Dividend Commencement Date with respect to Initial Series C Preferred Stock
and (2) the Original Issuance Date with respect to Series C Preferred Stock the
Original Issuance Date of which is after the Initial Issue Date.  If any
Dividend Payment Date occurs on a date that is not a Business Day, any accrued
dividends otherwise payable on such Dividend Payment Date shall be payable on
the next succeeding Business Day.  Each dividend shall be payable with respect
to Series C Preferred Stock held by Holders as they appear on the Corporation's
stock books on each Dividend Record Date. Dividends shall cease to accrue and
accumulate in respect of Series C Preferred Stock on any Redemption Date or
Conversion Date, as the case may be.

         (b) Dividend Payments.  Dividends on account of arrears for any past
Dividend Period and dividends in connection with any Redemption pursuant to
Section 5(a) may be declared and paid at any time, without reference to any
regular Dividend Payment Date, to Holders on such date as may be fixed by the
Board.

         (c) Dividends Paid in Series C Preferred Stock.  Notwithstanding
anything herein to the contrary, the Corporation shall, at its option, be
entitled in respect of any Dividend Period, in lieu of either paying any part
or all of a dividend in cash or permitting the unpaid dividend to accrue
additional dividends thereon, as provided in Section 3(f)(ii),  to declare and
pay any part or all of such dividend in additional fully paid and nonassessable
shares of Series C Preferred Stock with a Liquidation Preference equal to the
amount of the dividend payable in Series C Preferred Stock, with a fractional
number of shares to be issued in payment of any such dividend as the result
thereof to be rounded to the nearest 1/100th of share.  The Corporation shall
reserve 84,625 authorized but unissued shares of Series C Preferred Stock for
purposes of this Section 3(c) and not for any other purpose.  On or before the
15th Business Day after the Dividend Payment Date in respect of which shares of
Series C Preferred Stock will be issued as a dividend, the Corporation will
prepare and mail to each holder of Series C Preferred Stock a certificate
setting forth the determination of the number of shares of Series C Preferred
Stock issuable in payment of such dividend.  A dividend payment in Series C
Preferred Stock shall not be considered paid if the Corporation has not caused
share certificates representing such Series C Preferred Stock to be mailed or
delivered to the holders of the Series C Preferred Stock on which such dividend
is being paid on or before the 15th Business Day after the applicable Dividend
Payment Date.  If the above-mentioned share certificates are not mailed or
delivered on or before the 15th Business Day





                                       2
   3
after the applicable Dividend Payment Date, such unpaid dividends shall from
and after the applicable Dividend Payment Date accrue additional dividends in
respect thereof at the rate of 8% per annum as provided in Section 3(f)(ii),
until such accrued and unpaid dividends have been paid in full.

         (d) Junior Stock Dividends, Redemptions, etc.  So long as any Series C
Preferred Stock is outstanding, the Corporation shall not declare, pay or set
apart for payment any dividend on any Junior Stock or make any payment on
account of, or set apart for payment money for a sinking or other similar fund
for, the purchase, redemption or other retirement of, any Junior Stock, or any
warrants, rights, calls or options exercisable for any Junior Stock (except for
the purchase, redemption or other retirement of such securities which are debt
securities or Senior Stock or Parity Stock) or make any distribution in respect
thereof, either directly or indirectly, and whether in cash, obligations or
Capital Stock of the Corporation (or securities convertible or exchangeable for
obligations or Capital Stock of the Corporation) or other property (other than
dividends, payments, purchases, acquisitions, redemptions, retirements or
distributions in Junior Stock and cash in lieu of fractional shares) and shall
not permit any Subsidiary of the Corporation directly or indirectly to do any
of the same in respect of such Junior Stock (other than dividends, payments,
purchases, acquisitions, redemptions, retirements or distributions in Junior
Stock and cash in lieu of fractional shares) unless and until all dividend
arrearages on the Series C Preferred Stock have been paid in full (whether in
cash or in additional Series C Preferred Stock as provided in Section 3(c)) or
declared and a sum of money or a number of shares of additional Series C
Preferred Stock sufficient for the payment thereof has been set apart.

         (e) Pro Rata Dividend Payments.  Unless and until all dividend
arrearages on the Series C Preferred Stock have been paid in full (whether in
cash or in additional Series C Preferred Stock as provided in Section 3(c)),
all dividends declared by the Board upon Series C Preferred Stock or Parity
Stock, if any, shall be declared pro rata with respect to all Series C
Preferred Stock and Parity Stock then outstanding so that the amounts of any
dividends declared per share on the Series C Preferred Stock and such Parity
Stock bear the same ratio to each other at the time of declaration as all
accrued and unpaid dividends on the Series C Preferred Stock and the Parity
Stock bear to each other.

         (f) Dividend Computations.  (i) Dividends payable on the Series C
Preferred Stock shall be computed by multiplying 8% by the Liquidation
Preference and multiplying the result by a fraction, the numerator of which
shall be the number of days in the particular Dividend Period or, as the case
may be, the actual number of days lapsed in the Dividend Period for which
payable, and the denominator of which shall be 365.

         (ii) For any Dividend Period in which dividends are not paid in full
(whether in cash or in additional Series C Preferred Stock as provided in
Section 3(c)) on the Dividend Payment Date next succeeding the end of such
Dividend Period, then on such Dividend Payment Date such accrued and unpaid
dividends shall be added, solely for the purpose of calculating





                                       3
   4
dividends payable on the Series C Preferred Stock outstanding immediately prior
to such Dividend Payment Date, to the Liquidation Preference at the beginning
of the Dividend Period succeeding the Dividend Period as to which such
dividends were not paid and shall thereafter accrue additional dividends in
respect thereof at the rate of 8% per annum until such accrued and unpaid
dividends have been paid in full.

         (iii) The holders of Series C Preferred Stock shall not be entitled to
any dividends whether payable in cash, property or stock in excess of the full
cumulative dividends, as provided in Section 3 on the Series C Preferred Stock.

         4. Liquidation Preference. (a) Liquidation, Dissolution or Winding-Up.
In the event of any voluntary or involuntary liquidation, dissolution or
winding-up of the affairs of the Corporation, the Holders shall be entitled to
be paid out of the assets of the Corporation available for distribution to its
stockholders an amount equal to the Liquidation Preference for each share
outstanding plus all accrued but unpaid dividends thereon (which accrued but
unpaid dividends shall only be paid in the form of cash) to the date of such
liquidation, dissolution or winding-up, before any payment shall be made or any
assets distributed to the holders of any Junior Stock. If, however, the assets
of the Corporation are not sufficient to pay in full the liquidation payments
payable to the Holders and the holders of any outstanding Parity Stock, then
the holders of all such shares shall share ratably in such distribution of
assets in accordance with the amounts which would be payable on such
distribution if the amount to which the Holders and the holders of any
outstanding Parity Stock are entitled were paid in full.  Except as provided in
this Section 4(a), Holders shall not be entitled to any distribution in the
event of liquidation, dissolution or winding-up of the affairs of the
Corporation.

         (b) Asset Transfers, Mergers and Consolidations.  For the purposes of
this Section 4, neither the sale, conveyance, exchange or transfer (for cash,
stock, securities or other consideration) of all or substantially all of the
property or assets of the Corporation nor the consolidation or merger of the
Corporation with or into one or more corporations shall be deemed to be a
voluntary or involuntary liquidation, dissolution or winding-up of the affairs
of the Corporation.

         5. Redemption. (a) The Corporation (or any Subsidiary thereof) may, at
the Corporation's option redeem at any time on or after the Dividend
Commencement Date, from any source of funds legally available therefor, in
whole but not in part, as provided in Section 5(b), all of the Series C
Preferred Stock, at a redemption price payable in cash equal to (i) in respect
of a Redemption Date (as defined below) during the period from the Dividend
Commencement Date to, but not including, the date on which the Second Meeting
is held, at the Initial Redemption Price and (ii) in respect of a Redemption
Date on or after the Adjustment Date, at the Adjusted Redemption Price.





                                       4
   5
         (b) Redemption Procedure.  At least 10 Business Days and not more than
60 days prior to the date fixed by the Board for any redemption of the Series C
Preferred Stock (the "Redemption Date"), written notice (the "Redemption
Notice") shall be given by first class mail, postage prepaid, to each Holder on
the record date fixed for such redemption of the Series C Preferred Stock at
such Holder's address as the same appears on the Corporation's stock books.
The Redemption Notice shall state:

         (1) that such notice constitutes a Redemption Notice pursuant to
Section 5(a);

         (2) the Redemption Price;

         (3) the Redemption Date;

         (4) that the Holder is to surrender to the Corporation his certificate
or certificates representing the Series C Preferred Stock to be redeemed,
specifying the place or places where, and the manner in which, certificates for
Series C Preferred Stock are to be surrendered for redemption;

         (5) that dividends on the Series C Preferred Stock to be redeemed
shall cease to accumulate on the Redemption Date, unless the Corporation
defaults in the payment of the amounts necessary for such redemption, in which
case, dividends shall continue to accumulate from the Redemption Date until
such payment is made; and

         (6) all funds necessary for such redemption shall, as of the
Redemption Date, have been set aside by the Corporation separate and apart from
its other funds, in trust for the benefit of the Holders pursuant this Section
5.

         (ii) Each Holder shall surrender the certificate or certificates
representing such Series C Preferred Stock to the Corporation, duly endorsed,
in the manner and at the place designated in the Redemption Notice, and on the
Redemption Date the full Redemption Price for such shares so surrendered shall
be payable in cash to the Person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
cancelled and retired.

         (iii) If, on or before the Redemption Date, all funds necessary for
such redemption shall have been set aside by the Corporation, separate and
apart from its other funds, in trust for the pro rata benefit of the Holders of
the shares so called for redemption, so as to be and continue to be available
therefor, then, notwithstanding that any certificate for shares so called for
redemption shall not have been surrendered for cancellation, all shares so
called for redemption shall no longer be deemed outstanding on and after such
Redemption Date, and all rights with respect to such shares shall forthwith on
such Redemption Date cease and terminate, except only the right of the Holders
thereof to receive the amount payable on





                                       5
   6
redemption thereof, without interest. Any interest accrued on such funds shall
be paid to the Corporation from time to time, as it may request.

         (iv)  Any funds so set aside or deposited, as the case may be, by the
Corporation and unclaimed as of 90 days after such Redemption Date shall be
released or repaid to the Corporation, after which the Holders of the shares so
called for redemption shall look only to the Corporation for payment thereof.

         6.  Automatic Conversion. (a) Conversion and Effectiveness.  As of the
Conversion Date, the Series C Preferred Stock shall automatically be
reclassified as, and converted into, Common Stock, without any action of the
Holder, as follows (the "Conversion"):

         (i) Each share of Series C Preferred Stock shall be converted into
such number of fully paid and nonassessable shares of Common Stock that equals
the Liquidation Preference of the share of Series C Preferred Stock plus all
accrued but unpaid dividends thereon to, but not including, the Conversion Date
divided by the Conversion Price, provided, however, that if the Conversion Date
occurs after the Dividend Commencement Date, the Corporation shall be entitled,
in lieu of issuing Common Stock in respect of all or any part of the accrued
but unpaid dividends, to pay in cash all or any part of such unpaid dividends
(the "Cash Election").

         (ii) If the Corporation elects to exercise the Cash Election, it shall
do so on a pro rata basis in respect of the outstanding Series C Preferred
Stock; and

         (iii) Within 10 Business Days after the Conversion Date, written
notice of the Conversion and, if applicable, of the Cash Election shall be
given by first class mail, postage prepaid, to each Holder at such Holder's
address as the same appears on the Corporation's stock books, which notice
shall state (1) the number of shares of Common Stock into which the Series C
Preferred Stock has been converted and, if the Cash Election has been
exercised, that all or, as the case may be, that a specified part of the
accrued but unpaid dividends will be paid in cash pursuant to the Cash
Election, (2) the Conversion Date and (3) that the Holder is to surrender to
the Corporation his certificate or certificates formerly representing the
Series C Preferred Stock that has been converted into Common Stock and, if the
Cash Election has been exercised, the right to receive cash in an amount equal
to all or such portion of the accrued but unpaid dividends, as the case may be,
for which the Cash Election was exercised (the "Cash Portion").

         (b) Conversion Procedures. The Holder of any Series C Preferred Stock
converted shall surrender the certificate representing such Series C Preferred
Stock (the "Series C Preferred Stock Certificate") at the office or agency then
maintained by the Corporation for the transfer of the Series C Preferred Stock.
Such Holder shall state in the notice tendered with the Series C Stock
Certificate the name or names (with addresses) in which the certificate or
certificates for Common Stock which shall be issuable upon such conversion
shall be issued, and such





                                       6
   7
notice shall be accompanied by transfer taxes, if required. Each Series C
Preferred Stock Certificate surrendered for conversion shall, unless the shares
issuable on conversion are to be issued in the same name as the registration of
such Series C Preferred Stock Certificate, be duly endorsed by, or be
accompanied by instruments of transfer in form satisfactory to the Corporation
duly executed by, the Holder or such Holder's duly authorized attorney.

         As promptly as practicable, but in no event later than 10 Business
Days, after the surrender of such Series C Preferred Stock Certificate and the
receipt of such notice and funds, if any, as aforesaid, the Corporation shall
issue and shall simultaneously deliver at such office or agency to such Holder,
or on his written order, a certificate or certificates for the number of shares
of Common Stock issuable upon the conversion of such Series C Preferred Stock
represented by the Series C Preferred Stock Certificate so surrendered or
portion thereof in accordance with the provisions of this Section 6. If less
than all of the Series C Preferred Stock represented by a Series C Preferred
Stock Certificate surrendered for conversion is to be converted into Common
Stock as a result of the exercise of the Cash Election, the Corporation shall
simultaneously deliver to or upon the written order of the Holder of such
Series C Preferred Stock Certificate a check in an amount equal to the Cash
Portion.

         Upon the Conversion Date, (i) all Series C Preferred Stock shall no
longer be deemed to be outstanding and all rights with respect to such shares,
including the rights, if any, to receive notices and to vote, shall forthwith
cease, except only the right of the Holders thereof, subject to the provisions
of this Section 6, to receive Common Stock in exchange therefor and, if the
Cash Election has been exercised, the Cash Portion, and (ii) the person or
persons entitled to receive the Common Stock into which their Series C
Preferred Stock has been converted shall be treated for all purposes, including
dividends and other distributions thereafter in respect of Common Stock, as
having become the owners of such Common Stock.

         If any Series C Preferred Stock shall be called for redemption
pursuant to Section 5, such shares shall no longer be subject to conversion
into Common Stock under this Section 6.

         (c) The Conversion Price at which Series C Preferred Stock is
convertible into Common Stock shall be subject to adjustment from time to time
as provided in this Section 6(c) (unless otherwise indicated, all calculations
under this Section 6(c) shall be made to the nearest $0.01):

         (i) In case the Corporation shall (A) declare a dividend or make a
distribution on the outstanding Common Stock in Capital Stock of the
Corporation, (B) subdivide or reclassify the outstanding Common Stock into a
greater number of shares (or into other securities or property), or (C) combine
or reclassify the outstanding Common Stock into a smaller number of shares (or
into other securities or property), the Conversion Price in effect at the close
of business on the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution, or to be affected by such
subdivision, combination or other reclassification, shall be adjusted by
multiplying such Conversion Price by a fraction, the





                                       7
   8
numerator of which shall be the total number of outstanding shares of Common
Stock immediately prior to such event, and the denominator of which shall be
the total number of outstanding shares of Common Stock immediately after such
event. An adjustment made pursuant to this subparagraph (i) shall become
effective immediately after the record date for such event, or, if there is no
record date, upon the effective date for such event. Any Common Stock issuable
in payment of a dividend shall be deemed to have been issued immediately prior
to the time of the record date for such dividend for purposes of calculating
the number of outstanding shares of Common Stock under subparagraphs (ii) and
(iii) below. Adjustments pursuant to this subparagraph shall be made
successively whenever any event specified above shall occur.

         (ii) In case the Corporation shall fix a record date for the issuance
of rights, options or warrants to all holders of Common Stock entitling them
for a specified period not to exceed 21 days from the date of such issuance to
subscribe for or purchase Common Stock (or securities convertible into or
exchangeable for Common Stock) at a price per share (or having a conversion
price or exchange price per share, subject to normal antidilution adjustments)
less than the Current Market Price (as defined in subparagraph (vii) below) of
Common Stock on such record date, the Conversion Price in effect at the close
of business on such record date shall be reduced by multiplying such Conversion
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding on the date of issuance of such rights, options or
warrants plus the number of shares of Common Stock which the aggregate offering
exercise price for the total number of shares of Common Stock covered by such
rights, options or warrants would purchase at the Current Market Price as of
such record date, and the denominator of which shall be the number of shares of
Common Stock outstanding on the date of issuance of such rights, options or
warrants plus the number of additional shares of Common Stock offered for
subscription or purchase in connection with such rights, options or warrants.
Such adjustment shall be made whenever such rights, options or warrants are
issued, and shall become effective immediately after the record date for the
determination of stockholders entitled to receive such rights, options or
warrants. In case any rights, options or warrants referred to in this
subparagraph (ii) in respect of which an adjustment shall have been made shall
expire unexercised the Conversion Price shall be readjusted at the time of such
expiration to the Conversion Price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights, options or warrants.

         (iii) In case the Corporation shall fix a record date for the making
of a distribution to all holders of Common Stock (A) of shares of any class
other than Common Stock, (B) of evidences of indebtedness of the Corporation or
any Subsidiary, (C) of assets or other property or (D) of rights, options or
warrants (excluding those rights, options or warrants resulting in an
adjustment pursuant to subparagraph (ii) above), then in each such case the
Conversion Price shall be reduced so that such price shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (iii) by a fraction, the numerator of which shall be the Current
Market Price per share of Common Stock as of the record date for such





                                       8
   9
distribution, less the then fair market value (as determined by the Board,
whose reasonable determination shall be described in a resolution certified by
the Secretary or an Assistant Secretary of the Company to have been duly
adopted by the Board and to be in full force and effect on the date of such
certification (a "Board Resolution")) of the portion of the securities,
evidences of indebtedness, assets, property or rights, options or warrants so
distributed, as the case may be, which is applicable to one share of Common
Stock, and the denominator of which shall be the Current Market Price per share
of Common Stock as of the record date for such distribution. Such adjustment
shall be made successively whenever such a record date is fixed.

         (iv) In case the Corporation shall issue Common Stock for a
consideration per share less than the Current Market Price per share on the
date the Corporation fixes the offering price of such additional shares, the
Conversion Price shall be adjusted immediately thereafter so that it shall
equal the price determined by multiplying the Conversion Price in effect
immediately prior thereto by a fraction, of which the numerator shall be the
total number of shares of Common Stock outstanding immediately prior to the
issuance of such additional shares plus the number of shares of Common Stock
which the aggregate consideration received (determined as provided in
subparagraph (vi) below) for the issuance of such additional shares would
purchase at the Current Market Price per share and the denominator shall be the
number of shares of Common Stock outstanding immediately after the issuance of
such additional shares.  Such adjustment shall be made successively whenever
such an issuance is made.

         (v) In case the Corporation shall issue any securities convertible
into or exchangeable for Common Stock (excluding (A) securities issued in
transactions resulting in adjustment pursuant to subparagraphs (ii) and (iii)
above, (B) Series C Preferred Stock, and (C) upon conversion of any of such
securities) for a consideration per share of Common Stock deliverable upon
conversion or exchange of such securities (determined as provided in
subparagraph (vi) below and subject to normal antidilution adjustments) less
than the Current Market Price per share in effect immediately prior to the
issuance of such securities, the Conversion Price shall be adjusted immediately
thereafter so that it shall equal the price determined by multiplying the
Conversion Price in effect immediately prior thereto by a fraction, of which
the numerator shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of such securities plus the number of shares
of Common Stock which the aggregate consideration received (determined as
provided in subparagraph (vi) below) for such securities would purchase at the
Current Market Price per share and the denominator shall be the number of
shares of Common Stock outstanding immediately prior to such issuance plus the
maximum number of shares of Common Stock deliverable upon conversion of or in
exchange for such securities at the initial conversion or exchange price or
rate.  Such adjustment shall be made successively whenever such an issuance is
made.

         Upon the termination of the right to convert or exchange such
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustments made upon the
issuance of such convertible or exchangeable





                                       9
   10
securities been made upon the basis of the delivery of only the number of
shares of Common Stock actually delivered upon conversion or exchange of such
securities and upon the basis of the consideration actually received by the
Corporation (determined as provided in subparagraph (vi) below) for such
securities.

         (vi) For purposes of any computation pursuant to subparagraphs (iv) or
(v) above, the following shall apply:

         (A) notwithstanding the provisions of subparagraph (iv) or
subparagraph (v), no adjustment to the Conversion Price will be made (1) upon
the exercise of any of the options outstanding on the date hereof under the
Corporation's existing stock option plans or stock option agreements or upon
the exercise of any warrants of the Corporation outstanding on the date hereof;
(2) upon the issuance or exercise of options or warrants which may hereafter be
granted with the Board's approval, or exercised, under any employee benefit
plan of the Corporation to officers, directors, employees or consultants, but
only with respect to such options or warrants as are exercisable at prices no
lower than the Closing Price of the Common Stock as of the date of grant
thereof; (3) upon the sale of Common Stock pursuant to stock purchase or
similar plans of the Corporation to officers, directors, employees or
consultants, but only with respect to such sales at prices no lower than 85% of
the Closing Price of the Common Stock as of the date provided in the respective
plan; or (4) upon the sale of any Common Stock, warrants to purchase Common
Stock or convertible securities in a firm commitment underwritten public
offering, including shares sold upon the exercise of any overallotment option
granted to the underwriters in connection with such offering; or (5) with
respect to the issuance of Common Stock upon conversion of the Series C
Preferred Stock, adjusted as appropriate in each case in connection with any
stock split, merger, recapitalization or similar transaction;

         (B) in the case of the issuance of Common Stock for cash, the
consideration shall be the amount of such cash, provided that in no case shall
any deductions be made for any commissions, discounts, placement fees or other
expenses incurred by the Corporation for any underwriting or placement of the
issue or otherwise in connection therewith;

         (C) in the case of the issuance of Common Stock for a consideration in
whole or in part other than cash, the consideration other than cash shall be
deemed to be the fair market value thereof as determined by the Board, whose
reasonable determination shall be described in a Board Resolution; and

         (D) in the case of the issuance of securities convertible into or
exchangeable for Common Stock, the aggregate consideration received therefor
shall be deemed to be the consideration received by the Corporation for the
issuance of such securities plus the additional minimum consideration, if any,
to be received by the Corporation upon the conversion or exchange thereof (the
consideration in each case to be determined in the same manner as provided in
clauses (A) and (B) of this subparagraph (vi)).





                                       10
   11
         (vii) For the purpose of any computation under this Certificate of
Designation, (A) the "Current Market Price" per share at any date shall be
deemed to be the average of the daily Closing Price for the Common Stock for
the 10 consecutive Trading Days commencing 14 Trading Days before such date,
and (B) the "Closing Price" of the Common Stock means the last reported sale
price regular way reported on the NASDAQ Stock Market or its successor, or, if
not listed or admitted to trading on the NASDAQ Stock Market or its successor,
the last reported sale price regular way reported on any other stock exchange
or market on which the Common Stock is then listed or eligible to be quoted for
trading, or as reported by the National Quotation Bureau Incorporated.

         (viii) In any case in which this Section shall require that an
adjustment shall become effective immediately after a record date for an event,
the Corporation may defer until the occurrence of such event (A) issuing to the
Holder of any Series C Preferred Stock converted after such record date and
before the occurrence of such event the Common Stock issuable upon such
conversion by reason of the adjustment required by such event over and above
the Common Stock issuable upon such conversion before giving effect to such
adjustment and (B) paying to such Holder an amount in cash in lieu of a
fractional share of Common Stock pursuant to Section 6(h); provided, however,
that the Corporation shall deliver to such Holder a due bill or other
appropriate instrument evidencing such Holder's rights to receive such
additional Common Stock, and such cash, upon the occurrence of the event
requiring such adjustment.

         (ix) The Corporation may make such reductions in the Conversion Price,
in addition to those required pursuant to other subparagraphs of this Section
6, as it considers to be advisable so that any event treated for federal income
tax purposes as a dividend of stock or stock rights shall not be taxable to the
recipients.

         (x) In case of any consolidation with or merger of the Corporation
into another corporation, or in case of any sale or conveyance of assets to
another corporation of the assets of the Corporation as an entirety or
substantially as an entirety, lawful and adequate provisions shall be made
whereby each Holder of Series C Preferred Stock shall have the right to
receive, from such successor or purchasing corporation, as the case may be,
upon the basis and upon the terms and conditions specified herein, in lieu of
the Common Stock immediately theretofore receivable upon the conversion of such
Series C Preferred Stock, the kind and amount of shares of stock, other
securities, property or cash or any combination thereof receivable upon such
consolidation, merger, sale or conveyance by a holder of the number of shares
of Common Stock into which such Series C Preferred Stock might have been
converted immediately prior to such consolidation, merger, sale or conveyance.
In the case of any such consolidation, merger or sale of substantially all the
assets, appropriate provision shall be made with respect to the rights and
interests of the Holders to the end that the provisions hereof (including
provisions for adjustment of the Conversion Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of any conversion rights
hereunder.





                                       11
   12
         (xi) In case of any reclassification or change of the Common Stock
issuable upon conversion of Series C Preferred Stock (other than a change in
par value, or from par value to no par value, or as a result of a subdivision
or combination, but including any change in the Common Stock into two or more
classes or series of shares), or in case of any consolidation or merger of
another corporation into the Corporation in which the Corporation is the
continuing corporation and in which there is a reclassification or change
(including a change to the right to receive cash or other property) of the
Common Stock (other than a change in par value, or from par value to no par
value, or as a result of a subdivision or combination, but including any change
in the Common Stock into two or more classes or series of shares), lawful and
adequate provisions shall be made whereby each Holder of Series C Preferred
Stock shall have the right to receive, upon the basis and upon the terms and
conditions specified herein, in lieu of the Common Stock immediately
theretofore receivable upon the conversion of such Series C Preferred Stock,
the kind and amount of shares of stock, other securities, property or cash or
any combination thereof receivable upon such reclassification, change,
consolidation or merger, by a holder of the number of shares of Common Stock
into which such Series C Preferred Stock might have been converted immediately
prior to such reclassification, change, consolidation or merger.

         (xii) If the Corporation repurchases (by way of tender offer, exchange
offer or otherwise) any Common Stock for a per share consideration which
exceeds the Current Market Price of a share of Common Stock on the date
immediately prior to such repurchase, the Conversion Price shall be reduced so
that such price shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the effectiveness of the Conversion Price
reduction contemplated by this subparagraph (xii) by a fraction, the numerator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such acquisition multiplied by the Current Market Price per share of
the Common Stock on the immediately preceding Trading Day, and the denominator
shall be the sum of (A) the fair market value (as determined in good faith by
the Board) of the aggregate consideration payable to stockholders as a result
of such acquisition, and (B) the product of the number of shares of Common
Stock outstanding immediately following such acquisition and the Current Market
Price per share of the Common Stock on such immediately preceding Trading Day,
such reduction to become effective immediately prior to the opening of business
on the day following such acquisition.

         (xiii) If any event occurs as to which the foregoing provisions of
this Section 6(c) are not strictly applicable or, if strictly applicable, would
not, in the good faith judgment of the Board, fairly protect the conversion
rights of the Series C Preferred Stock in accordance with the essential intent
and principles of such provisions, then the Board shall make such adjustments
in the application of such provisions, in accordance with such essential intent
and principles, as shall be reasonably necessary, in the good faith opinion of
the Board, to protect such conversion rights as aforesaid, but in no event
shall any such adjustment have the effect of increasing the Conversion Price,
or otherwise adversely affect the Holders.





                                       12
   13

         (xiv) For purposes of Section 6(c), Common Stock owned or held at any
relevant time by, or for the account of, the Corporation in its treasury or
otherwise, shall not be deemed to be outstanding for purposes of the
calculation and adjustments described therein.

         (xv) Nothing in this Section 6 shall in any way affect the
Corporation's right to redeem the Series C Preferred Stock as provided in
Section 5, including redemptions in contemplation of transactions referred to
in the foregoing provisions of this Section 6(c).

         (d) Conversion Price Adjustment Deferred. Notwithstanding the
foregoing provisions of this Section 6, (i) no adjustment in the number of
shares of Common Stock into which any Series C Preferred Stock is convertible
shall be required unless such adjustment would require an increase or decrease
in such number of shares of at least 1% and (ii) no adjustment in the
Conversion Price shall be required unless such adjustment would require an
increase or decrease in the Conversion Price of at least $.01 per share;
provided, however, that any adjustments which by reason of this paragraph (d)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section 6 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be.

         (e) Adjustment Report. Whenever any adjustment is required in the
shares into which any Series C Preferred Stock is convertible, the Corporation
shall forthwith cause a notice of such adjustment, setting forth the adjusted
Conversion Price and the calculation thereof to be mailed to the Holders at
their respective addresses as shown on the Corporation's stock books.

         (f) Common Stock. For the purposes of this Section 6, the term "Common
Stock" shall mean (i) the Common Stock or (ii) any other class of stock
resulting from successive changes or reclassifications of such Common Stock
consisting solely of changes in par value or from no par value to par value, or
from par value to no par value. If at any time as a result of an adjustment
made pursuant to the provisions of Section 6(c), the Holder of any Series C
Preferred Stock thereafter surrendered for conversion shall become entitled to
receive any other class of stock such other shares so receivable upon
conversion of any Series C Preferred Stock shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to
the provisions with respect to the Common Stock contained in Section 6(c), and
the other provisions of this Section 6 with respect to the Common Stock shall
apply on like terms to any such other shares.

         (g) Fractional Shares. The Corporation shall not be required to issue
fractional shares of Common Stock upon the conversion of any Series C Preferred
Stock. If more than one share of Series C Preferred Stock shall be surrendered
for conversion at one time by the same Holder, the number of full shares of
Common Stock issuable upon conversion thereof shall be computed on the basis of
the aggregate number of shares so surrendered. If any fractional interest in a
share of Common Stock would be deliverable upon the conversion of any Series C





                                       13
   14
Preferred Stock, the Corporation may pay, in lieu thereof, in cash the
appropriate amount based on the Conversion Price.

         7. Voting Rights. The Series C Preferred Stock shall have only the 
following voting rights:

         (a) Series C Director; Joint Director.

         (i)     The number of directors of the Corporation shall be as from
time to time fixed by, or determined in the manner provided in, the Charter
and the Corporation's bylaws.  One such director shall be designated as a
"Series C Director" and shall be elected by the Majority Holders voting
together as a single class and one such director shall be designated as "Joint
Director" and shall be an Independent director nominated by the Majority
Holders and approved by the Board in its sole discretion. The rights of the
Holders with respect to the Joint Director shall automatically terminate if
the total Liquidation Preference with respect to the Series C Preferred Stock
owned by the Initial Purchaser plus all accrued and unpaid dividends thereon
falls below 66 2/3% of the total Liquidation Preference of the then outstanding
Series C Preferred Stock plus all accrued and unpaid dividends thereon. The
Majority Holders shall have the exclusive right to remove such Series C
Director without cause at any time and to designate another individual as the
Series C Director.  The term of office of the first Series C Director shall
commence upon the nomination and election of such Director, at the option of
the Majority Holders at any time after the Initial Issue Date, to expire at the
annual meeting of stockholders held in 1998.  The Series C Director shall be
elected annually at the time of each annual meeting of stockholders for a term
of office to expire at the first succeeding annual meeting of stockholders
after his election and until his successor is duly elected and has qualified
or until his earlier resignation or removal.  Such election may be effected
by written consent executed by the Majority Holders.

         (ii)    With respect to filling the vacancy on the Board with respect
to the initial Joint Director, the Holders shall give written notice to the
Secretary of the Corporation of the identity of the person nominated by such
holders.  Such written notice shall be executed, manually, or by photocopy or
facsimile, by the Majority Holders.  The person so nominated shall be
Independent. Upon receipt of such written notice, the Board shall have 17
Business Days in which to approve or disapprove such nominee.  If the Board
approves such nominee, such nominee shall immediately fill such vacancy.  If
the Board disapproves such nominee, the Secretary of the Corporation shall
immediately give written notice thereof to all Holders. If such a written
notice from the Secretary has not been received by such Holders 17 business
days after the receipt by the Corporation of such written notice of nomination,
the Board shall be conclusively deemed to have approved such nominee and such
nominee shall immediately fill such vacancy.  If such written notice from the
Secretary has been so received within such 17 Business Days, such Holders may
nominate another Independent person by written notice to the Secretary, subject
to the same approval process as herein above provided.  Such process of
nomination and approval or disapproval shall continue until an Independent
person is nominated who is approved or





                                       14
   15
deemed to be approved by the Board.  No nominations for such director shall be
made or received other than as described in this Section 7(a)(ii).

         (iii)   With respect to the nomination and election of succeeding
Joint Directors, the Holders shall give timely written notice to the Secretary
of the Corporation of the identity of the person nominated by such Holders.
Such written notice shall be executed, manually, or by photocopy or facsimile,
by the Majority Holders.  Such written notice shall be timely if received at
the Corporation's principal executive office not fewer than 90 days nor more
than 120 days before the meeting of stockholders at which such director is to
be elected.  The person so nominated shall be Independent. Upon receipt of such
written notice, the Board shall have 17 Business Days in which to approve or
disapprove such nominee.  If the Board disapproves such nominee, the Secretary
of the Corporation shall immediately give written notice thereof to all
Holders. If such a written notice from the Secretary has not been received by
such Holders 17 Business Days after the receipt by the Corporation of such
written notice of nomination, the Board shall be conclusively deemed to have
approved such nominee. If such written notice from the Secretary has been so
received within such 17 Business Days, such Holders may nominate another
Independent person by written notice to the Secretary, subject to the same
approval process as herein above provided.  Such process of nomination and
approval or disapproval shall continue until an Independent person is nominated
who is approved or deemed to be approved by the Board.  No nominations for such
director shall be made or received other than as described in this Section
7(a)(iii).  Election of such person shall be by the holders of Common Stock.

         (iv)    A vacancy of the Series C Director position shall be filled
only by a majority vote of or written consent of the Majority Holders. A
vacancy of the position of Joint Director shall be filled only by the Board,
following nomination by the Majority Holders, pursuant to the procedure
described in Section 7(a)(ii).  Directors chosen pursuant to any of the
foregoing provisions shall hold office for a term expiring at the next annual
meeting of stockholders and until their successors are duly elected and have
qualified or until their earlier resignation or removal.  If none of the Series
C Preferred Stock remains outstanding, the Series C Director shall be deemed to
have resigned immediately as of such date.

         (b) Issuance of Senior or Parity Stock.  So long as any Series C
Preferred Stock is outstanding, without the affirmative vote or consent of the
Majority Holders, voting or consenting, as the case may be, as one class, given
in person or by proxy, either in writing or by resolution adopted at an annual
or special meeting, the Corporation shall not (i) issue, or reclassify any
authorized stock of the Corporation into, or issue any obligation or security
convertible into or evidencing a right to purchase, any Senior Stock or Parity
Stock or any preferred stock having voting rights senior or equal to those of
the Series C Preferred Stock, (ii) reclassify the Series C Preferred Stock, or
(iii) amend its Charter or this Certificate of Designation for the Series C
Preferred Stock so as to affect adversely the specified rights, preferences,
privileges or voting rights of Holders or to increase or decrease the
authorized number of shares of Series C Preferred Stock.  Nothing in the
immediately preceding sentence





                                       15
   16
shall prohibit or otherwise restrict the Company from issuing Series C
Preferred Stock pursuant to Section 3(c).

         (c) Number of Votes.  In any case in which the Holders shall be
entitled to vote as a separate class pursuant to this Section 7 or pursuant to
Delaware law, each Holder shall be entitled to one vote for each share of
Series C Preferred Stock then held.

         (d) No Vote on Other Matters.  Except as provided above or as may be
required by Delaware law, the Holders shall not be entitled to vote on any
matters submitted to holders of the Corporation's Capital Stock.

         8. Exclusion of Other Rights.  Except as may otherwise be required by
Delaware law, the Series C Preferred Stock shall not have any voting powers,
preferences and relative, participating, optional or other special rights,
other than those specifically set forth in this Certificate of Designation.

         9. Reissuances.  Series C Preferred Stock that has been issued and
reacquired by the Corporation (or any Subsidiary thereof) in any manner,
including shares surrendered to the Corporation upon conversion, and shares
purchased or redeemed, shall (upon compliance with any applicable provisions of
the laws of Delaware) have the status of authorized and unissued preferred
stock undesignated as to series of preferred stock and may be re-designated and
reissued as part of any series of preferred stock.

         10. Business Day. If any payment or redemption shall be required by
the terms hereof to be made on a day that is not a Business Day, such payment
or redemption shall be made on the immediately succeeding Business Day.

         11. Headings of Sections. The headings of the various Sections hereof
are for convenience of reference only and shall not affect the interpretation
of any of the provisions hereof.

         12. Severability of Provisions. If any right, preference or limitation
of the Series C Preferred Stock set forth in this Certificate of Designation
(as it may be amended from time to time) is invalid, unlawful or incapable of
being enforced by reason of any rule or law or public policy, all other rights,
preferences and limitations set forth in this Certificate of Designation (as so
amended) which can be given effect without the invalid, unlawful or
unenforceable right, preference or limitation shall, nevertheless, remain in
full force and effect, and no right, preference or limitation herein set forth
shall be deemed dependent upon any other such right, preference or limitation
unless so expressed herein.

         13.  Record Holders.  The Corporation and the transfer agent, if any,
for the Series C Preferred Stock may deem and treat the record holder of any
Series C Preferred Stock as the





                                       16
   17
true and lawful owner thereof for all purposes, and neither the Corporation nor
