               CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS

                                       of

                            SERIES A PREFERRED STOCK

                                       of

                            WIRELESS FACILITIES, INC.

     I, Masood K. Tayebi, Chief Executive Officer of WIRELESS FACILITIES, INC.,
a corporation organized and existing under the laws of the State of Delaware
(the "Corporation"), in accordance with the provisions of Section 151 of the
Delaware General Corporation Law, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors of the
Corporation (the "Board of Directors") by the Certificate of Incorporation of
the Corporation and by Section 151(g) of the Delaware General Corporation Law,
on October 9, 2001, the Board of Directors adopted the following resolution,
creating a series of shares of convertible preferred stock, Series A, designated
as "Series A Preferred Stock":

     "RESOLVED, that pursuant to the authority vested in the Board of Directors
     (the "Board of Directors") of WIRELESS FACILITIES, INC., a corporation
     organized and existing under the laws of the State of Delaware (the
     "Corporation"), by the Certificate of Incorporation of the Corporation (the
     "Certificate of Incorporation"), the Board of Directors does hereby provide
     for the authorization and issuance of a series of convertible preferred
     stock, Series A, par value U.S.$0.001 per share, of the Corporation, to be
     designated "Series A Preferred Stock," initially consisting of 63,637
     shares, and to the extent that the designations, powers, preferences, and
     relative participating, optional, or other special rights, and the
     qualifications, limitations, and restrictions of the Series A Preferred
     Stock are not stated and expressed in the Certificate of Incorporation, the
     Board of Directors does hereby fix and herein state and express such
     designations, powers, preferences, and relative participating, optional, or
     other special rights, and the qualifications, limitations, and restrictions
     thereof, as follows:

1.   Designation and Rank.

     (a)  Sixty-three thousand six hundred thirty-seven (63,637) shares of the
preferred stock of the Corporation, par value $0.001 per share, shall be
designated and known as the "Series A Preferred Stock."

     (b)  The Series A Preferred Stock shall rank senior and prior to the common
stock, par value U.S.$0.001 per share, of the Corporation (the "Common Stock"),
and all other classes or series of the capital stock (other than preferred
stock) of the Corporation (now or hereafter authorized or issued), with respect
to the payment of any dividends, the conversion rights set forth herein and any
payment upon liquidation or redemption. The Corporation may not issue any
additional classes or series of preferred stock with liquidation, redemption or
conversion rights or right of payment of any kind that is senior to the Series A
Preferred Stock, except pursuant to Section 12.


                                       1.





2.   Dividend Rights.

     From and after the date hereof, when and if the Board of Directors declares
a dividend or distribution payable with respect to the then-outstanding shares
of Common Stock (other than in additional shares of Common Stock or Common Stock
Equivalents (as defined in Section 4(e)(i) below), the holders of the Series A
Preferred Stock shall be entitled to the amount of dividends per share in the
same form as such Common Stock dividends that would be payable on the largest
number of whole shares of Common Stock into which a holder's aggregate shares of
Series A Preferred Stock could then be converted pursuant to Section 4 hereof
(such number to be determined as of the record date for the determination of
holders of Common Stock entitled to receive such dividend).

3.   Liquidation Rights.

     (a)  Liquidation Events. The occurrence of any of the following events
shall be deemed a "Liquidation": (i) any liquidation, dissolution, or winding-up
of the affairs of the Corporation; (ii) any transaction or series of related
transactions in which securities of the Corporation representing 50% or more of
the combined voting power of the Corporation's then outstanding voting
securities are acquired by a person, entity or group of related persons or
entities, excluding any consolidation or merger effected exclusively to change
the domicile of the Corporation; (iii) any consolidation, merger or
reorganization of the Corporation with or into any other corporation or other
entity or person pursuant to which the holders of the Corporation's outstanding
securities receive, pursuant to such transaction, securities in the surviving
entity that represent less than 50% of the voting power of such surviving
entity; or (iv) any sale, lease, exclusive license or other disposition of all
or substantially all of the assets of the Corporation.

     (b)  Liquidation Preference.

          (i) In the event of any Liquidation, whether voluntary or involuntary,
before any payment of cash or distribution of other property shall be made to
the holders of Common Stock, or any other class or series of stock subordinate
in liquidation preference to the Series A Preferred Stock, the holders of the
Series A Preferred Stock shall be entitled to receive out of the assets of the
Corporation legally available for distribution to its stockholders, on behalf of
each share of Series A Preferred Stock held by such holder, U.S.$550.00 (the
"Original Issue Price") (as appropriately adjusted for any combinations,
divisions, or similar recapitalizations affecting the Series A Preferred Stock
after issuance) and all accumulated or accrued and unpaid dividends thereon
(collectively, the "Series A Liquidation Preference").

          (ii) If, upon any Liquidation, the assets of the Corporation available
for distribution to its stockholders are insufficient to pay the holders of the
Series A Preferred Stock the full amounts to which they are entitled pursuant to
clause (b)(i) above, the holders of the Series A Preferred Stock shall share pro
rata in any distribution of assets in proportion to the respective amounts which
would be payable to the holders of the Series A Preferred Stock and any other
class or series of capital stock of the Corporation ranking on par with the
Series A Preferred Stock in respect of the shares held by them if all amounts
payable to them in respect of such were paid in full pursuant to clause (b)(i)
above.


                                       2.





          (iii)  After the distributions described in clause (b)(i) or (b)(ii)
above have been paid, subject to the rights of any other class or series of
capital stock of the Corporation that may from time to time come into existence,
the remaining assets of the Corporation available for distribution to
stockholders shall be distributed among the holders of Common Stock pro rata
based on the number of shares of Common Stock held by each.

     (c)  Non-Cash Distributions. If any distribution to be made pursuant to
this Section 3 is to be paid other than in cash or Common Stock or Common Stock
Equivalents, the value of such distribution will be deemed its fair market value
as determined in good faith by the Board of Directors. Any securities shall be
valued as follows:

          (i)  Securities not subject to investment letter or other similar
restrictions on free marketability covered by clause (ii) below:

               (1)  if traded on a securities exchange or through the Nasdaq
National Market, the value shall be deemed to be the average of the closing
prices of the securities on such quotation system over the thirty (30) trading
day period ending three (3) trading days prior to the occurrence of the
Liquidation;

               (2)  if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty (30) trading day period ending three (3) trading
days prior to the occurrence of the Liquidation; and

               (3)  if there is no active public market, the value shall be the
fair market value thereof, as determined by the Board of Directors.

          (ii) The method of valuation of securities subject to investment
letter or other restrictions on free marketability (other than restrictions
arising solely by virtue of a stockholder's status as an affiliate or former
affiliate) shall be to effectuate an appropriate discount from the market value,
as determined by clause (i)(1), (2) or (3) of this Section 3(c), so as to
reflect the approximate fair market value thereof, as determined by the Board of
Directors.

          (iii) The holders of at least a majority of the outstanding Series A
Preferred Stock shall have the right to challenge any determination by the Board
of Directors of fair market value pursuant to this Section 3(c), in which case
the determination of fair market value shall be made by an independent appraiser
selected jointly by the Board of Directors and the challenging parties, the cost
of such appraisal to be borne equally by the Corporation and the challenging
parties.

4.   Conversion Rights.

     The holders of the Series A Preferred Stock shall have conversion rights as
follows (the "Conversion Right"):

     (a)  Conversion Price. The "Conversion Price" shall, initially, be U.S.
$5.50 per share and shall be subject to adjustment as set forth below in
Sections 4(e) and 4(f).


                                       3.





     (b)  Automatic Conversion. If the closing price for the shares of the
Corporation's Common Stock (trading on a securities exchange or through Nasdaq
National Market or other national exchange or market) exceeds $11.00 per share
(as adjusted for events described in Section 4(e)(ii) and 4(e)(iii) below) for
any thirty consecutive trading day period that begins after July 29, 2004, then,
upon such occurrence, each share of Series A Preferred Stock shall be
automatically converted into such number of fully paid and non-assessable shares
of Common Stock as is determined by dividing (x) the Original Issue Price of
such share of Series A Preferred Stock (including any accumulated or accrued but
unpaid dividends thereon) by (y) the Conversion Price. The date of such
conversion is herein referred to as the "Conversion Date."

     (c)  Optional Conversion. The holders of the Series A Preferred Stock shall
have the right, at any time, to convert the shares of Series A Preferred Stock
held by such holder into that number of shares of Common Stock into which such
shares are convertible pursuant to Section 4(b) ("Optional Conversion"). In the
event of any Optional Conversion, the date of the such conversion shall be
referred to as the "Optional Conversion Date."

     (d)  Mechanics of Conversion. On the Conversion Date or Optional Conversion
Date, as the case may be, (x) each holder shall tender such holder's shares of
Series A Preferred Stock to the Corporation for cancellation, free and clear of
encumbrances of any type or nature, and (y) the Corporation shall cause to be
delivered to such holder a number of shares of Common Stock as calculated
pursuant to Section 4(b) above, free and clear of encumbrances of any type or
nature. Each holder and the Corporation shall take all other necessary or
appropriate actions in connection with or to effect such closing.

     (e)  Certain Adjustments. To the extent that the holders of Series A
Preferred Stock do not participate fully with other stockholders of the
Corporation with respect to dividends paid pursuant to Section 2 hereof, the
following adjustments shall be made to the Conversion Price:

          (i) Adjustment for Common Stock Dividends and Distributions. If, at
any time after the original issue date of the Series A Preferred Stock (the
"Original Issue Date"), the Corporation makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in additional shares of Common Stock or Common Stock
Equivalents, in each such event the Conversion Price that is then in effect
shall be decreased as of the time of such issuance or, in the event such record
date is fixed, as of the close of business on such record date, by multiplying
the Conversion Price then in effect by a fraction (i) the numerator of which is
the total number of shares of Common Stock and Common Stock Equivalents issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (ii) the denominator of which is the total
number of shares of Common Stock and Common Stock Equivalents issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date plus the number of shares of Common Stock or Common
Stock Equivalents issuable in payment of such dividend or distribution;
provided, however, that if such record date is fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor,
the Conversion Price shall be recomputed accordingly as of the close of business
on such record date and thereafter the Conversion Price shall be adjusted
pursuant to this Section 4(e)(i) to reflect the actual payment of such dividend
or distribution.


                                       4.





                A "Common Stock Equivalent" shall mean each share of Common
Stock into which securities or property or rights are convertible, exchangeable
or exercisable for or into shares of Common Stock, or otherwise entitle the
holder thereof to receive directly or indirectly, any of the foregoing.

          (ii)  Adjustments for Stock Splits, Stock Subdivisions and
Combinations. If, at any time after the Original Issue Date, the Corporation
subdivides or combines the Common Stock without making a corresponding
subdivision or combination of the Series A Preferred Stock, (A) in the case of a
subdivision (including a stock split), the Conversion Price in effect
immediately prior to such event shall be proportionately decreased and the
number of shares of Common Stock purchasable thereunder shall be proportionately
increased, and (B) in the case of a combination (including a reverse stock
split), the Conversion Price in effect immediately prior to such event shall be
proportionately increased and the number of shares of Common Stock purchasable
thereunder shall be proportionately decreased. Any adjustment under this Section
4(e)(ii) shall become effective at the close of business on the date the
subdivision or combination becomes effective.

          (iii) Adjustments for Reclassification, Reorganization and
Consolidation. In case of (A) any reclassification, reorganization, change or
conversion of securities of the class issuable upon conversion of the Series A
Preferred Stock (other than a change in par value, or from par value to no par
value) into other shares or securities of the Corporation, or (B) any merger or
consolidation of the Corporation with or into another entity (other than a
Liquidation or a merger or consolidation with another entity in which the
Corporation is the acquiring and the surviving entity and that does not result
in any reclassification or change of outstanding securities issuable upon
conversion of the Series A Preferred Stock) each holder of shares of Series A
Preferred Stock shall have the right to receive, in lieu of the shares of Common
Stock otherwise issuable upon the conversion of its shares of Series A Preferred
Stock (and accumulated or accrued and unpaid dividends then-outstanding
thereunder) in accordance with Section 4(b), the kind and amount of shares of
stock and other securities, money and property receivable upon such
reclassification, reorganization, change, merger or consolidation upon
conversion by a holder of the maximum number of shares of Common Stock into
which such shares of Series A Preferred Stock could have been converted
immediately prior to such reclassification, reorganization, change, merger or
consolidation, all subject to further adjustment as provided herein or with
respect to such other securities or property by the terms thereof. The
provisions of this clause (iii) shall similarly attach to successive
reclassifications, reorganizations, changes, mergers and consolidations.

     (f)  Antidilution Adjustments. To the extent that (i) the Corporation
issues after the Original Issue Date and before April 29, 2003, Additional
Shares of Common Stock (as defined below) (in one or more transactions, whether
or not related), (ii) each such issuance is at an Effective Price (as defined
below) per share less than Conversion Price then in effect and (iii) the
aggregate gross proceeds of such issuances exceed $15 million, then the
Conversion Price shall be adjusted to equal the lowest Effective Price received
by the Corporation pursuant to any such issuance. The previous sentence will
apply to any issuances of Additional Shares of Common Stock after the $15
million threshold has been met (provided any such issuance is below the
Conversion Price then in effect) but will not apply to any issuance of
Additional Shares of


                                       5.



Common Stock occurring after April 29, 2003. Notwithstanding the foregoing, the
Conversion Price shall in no event be lower than U.S.$3.77.

          (i)   For the purpose of making any adjustment required under Section
4(f), the consideration received by the Company for any issue or sale of
securities shall (A) to the extent it consists of cash, be computed at the net
amount of cash received by the Company after deduction of any underwriting or
similar commissions, compensation or concessions paid or allowed by the Company
in connection with such issue or sale but without deduction of any expenses
payable by the Company (except for purposes of determining if the $15 million
threshold referred to above has been met, in which case the consideration
received will be deemed to be the aggregate gross proceeds received by the
Company), (B) to the extent it consists of property other than cash, be computed
at the fair value of that property as determined in good faith by the Board of
Directors, and (C) if Additional Shares of Common Stock, Convertible Securities
(as defined below) or rights or options to purchase either Additional Shares of
Common Stock or Convertible Securities are issued or sold together with other
stock or securities or other assets of the Company for a consideration which
covers both, be computed as the portion of the consideration so received that
may be reasonably determined in good faith by the Board of Directors to be
allocable to such Additional Shares of Common Stock, Convertible Securities or
rights or options; provided, however, that the holders of at least a majority of
the outstanding Series A Preferred Stock shall have the right to challenge any
determination by the Board of Directors of fair market value pursuant to this
Section 4(f)(i), in which case the determination of fair market value shall be
made by an independent appraiser selected jointly by the Board of Directors and
the challenging parties, the cost of such appraisal to be borne equally by the
Corporation and the challenging parties.

          (ii)  For the purpose of the adjustment required under this Section
4(f), if the Company issues or sells (A) stock or other securities convertible
into, Additional Shares of Common Stock (such convertible stock or securities
being herein referred to as "Convertible Securities") or (B) rights or options
for the purchase of Additional Shares of Common Stock or Convertible Securities
and if the Effective Price of such Additional Shares of Common Stock is less
than the Conversion Price, in each case the Company shall be deemed to have
issued at the time of the issuance of such rights or options or Convertible
Securities the maximum number of Additional Shares of Common Stock issuable upon
exercise or conversion thereof and to have received as consideration for the
issuance of such shares an amount equal to the total amount of the
consideration, if any, received by the Company for the issuance of such rights
or options or Convertible Securities, plus, in the case of such rights or
options, the minimum amounts of consideration, if any, payable to the Company
upon the exercise of such rights or options, plus, in the case of Convertible
Securities, the minimum amounts of consideration, if any, payable to the Company
(other than by cancellation of liabilities or obligations evidenced by such
Convertible Securities) upon the conversion thereof; provided that if in the
case of Convertible Securities the minimum amounts of such consideration cannot
be ascertained, but are a function of antidilution or similar protective
clauses, the Company shall be deemed to have received the minimum amounts of
consideration without reference to such clauses; provided further that if the
minimum amount of consideration payable to the Company upon the exercise or
conversion of rights, options or Convertible Securities is reduced over time or
on the occurrence or non-occurrence of specified events other than by reason of
antidilution adjustments, the Effective Price shall be recalculated using the
figure to which such minimum amount of consideration is


                                       6.



reduced; provided further that if the minimum amount of consideration payable to
the Company upon the exercise or conversion of such rights, options or
Convertible Securities is subsequently increased, the Effective Price shall be
again recalculated using the increased minimum amount of consideration payable
to the Company upon the exercise or conversion of such rights, options or
Convertible Securities. No further adjustment of the Conversion Price, as
adjusted upon the issuance of such rights, options or Convertible Securities,
shall be made as a result of the actual issuance of Additional Shares of Common
Stock on the exercise of any such rights or options or the conversion of any
such Convertible Securities. If any such rights or options or the conversion
privilege represented by any such Convertible Securities shall expire without
having been exercised, the Conversion Price, as adjusted upon the issuance of
such rights, options or Convertible Securities, shall be readjusted to the
Conversion Price which would have been in effect had an adjustment been made on
the basis that the only Additional Shares of Common Stock so issued were the
Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such rights or options or rights of conversion of such Convertible
Securities, and such Additional Shares of Common Stock, if any, were issued or
sold for the consideration actually received by the Company upon such exercise,
plus the consideration, if any, actually received by the Company for the
granting of all such rights or options, whether or not exercised, plus the
consideration received for issuing or selling the Convertible Securities
actually converted, plus the consideration, if any, actually received by the
Company (other than by cancellation of liabilities or obligations evidenced by
such Convertible Securities) on the conversion of such Convertible Securities.

     "Additional Shares of Common Stock" shall mean all shares of Common Stock
issued by the Company or deemed to be issued pursuant to this Section 4(f),
whether or not subsequently reacquired or retired by the Company other than (A)
shares of Common Stock and/or options, warrants or other Common Stock purchase
rights, and the Common Stock issued or issuable pursuant to such options,
warrants or other rights to employees, officers or directors of, or consultants
or advisors to the Company or any subsidiary pursuant to stock purchase or stock
option plans or other arrangements that are approved by the Board; (B) shares of
Common Stock issued or issuable pursuant to any equipment loan or leasing
arrangement, or debt financing from a bank or similar financial institution; (C)
shares of Common Stock issued or issuable in connection with licensing
transactions involving the Company and other entities, including (1) joint
ventures, manufacturing, marketing or distribution arrangements or (2)
technology transfer or development arrangements; provided that such transactions
in (1) and (2) and the issuance of shares therein has been approved by a
majority of the members of the Company's Board of Directors and the aggregate
number of shares so issued does not exceed four million (4,000,000)(as adjusted
for stock splits, stock dividends, stock combinations, recapitalizatons and the
like); and (D) any other issuances approved by the holders of a majority of the
Series A Preferred Stock then outstanding.

     The "Effective Price" of Additional Shares of Common Stock shall mean the
quotient determined by dividing the total number of Additional Shares of Common
Stock issued or sold, or deemed to have been issued or sold by the Company under
this Section 4(f), into the aggregate consideration received, or deemed to have
been received by the Company for such issue under this Section 4(f), for such
Additional Shares of Common Stock.

                                       7.



5.   Other Distributions.

     In the event the Corporation provides the holders of its Common Stock with
consideration that is not otherwise addressed in Section 4 (including, without
limitation, declaring a distribution payable in securities, assets, cash or
evidences of indebtedness issued by other persons or the Corporation (excluding
cash dividends declared and paid by the Corporation out of retained earnings)),
then, in each such case, the holders of the Series A Preferred Stock shall be
entitled to a pro rata share of any such distribution as though such holders
were holders of the number of shares of Common Stock of the Corporation as
though the Series A Preferred Stock had been converted in whole as of the record
date fixed for the determination of the holders of Common Stock of the
Corporation entitled to receive such distribution.

6.   Recapitalizations.

     If at any time there occurs a recapitalization of the Common Stock (other
than a subdivision, combination, or merger or sale of assets provided for in
Section 4 hereof), the holders of the Series A Preferred Stock shall be entitled
to receive upon conversion of the Series A Preferred Stock the number of shares
of capital stock or other securities or property of the Corporation or otherwise
to which a holder of the Common Stock deliverable upon conversion would have
been entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of Section 4 hereof with
respect to the rights of the holders of the Series A Preferred Stock after the
recapitalization to the end that the provisions of Section 4 hereof (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series A Preferred Stock) shall be applicable
after that event as nearly equivalent as may be practicable.

7.   No Impairment.

     The Corporation will not, by amendment of the Certificate of Incorporation
or through any reorganization, recapitalization, transfer of assets,
consolidation, merger, dissolution, issuance or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions hereof
and in the taking of all such action as may be necessary or appropriate in order
to protect the Conversion Right of the holders of the Series A Preferred Stock
against impairment.

8.   No Fractional Shares and Certificate as to Adjustments.

     (a) No fractional shares of Common Stock will be issued upon the conversion
of any share or shares of the Series A Preferred Stock. All shares of Common
Stock (including fractions thereof) issuable upon conversion of more than one
share of Series A Preferred Stock by a holder shall be aggregated for purposes
of determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of a fraction of a share of Common Stock, the Corporation
shall, in lieu of issuing any fractional share, pay the holder otherwise
entitled to such fraction a sum in cash equal to such fraction multiplied by the
closing price of the Corporation's Common Stock on the Nasdaq National Market
(or any other national securities exchange on which the Common

                                       8.



Stock is then traded) on the day immediately preceding the conversion. All
calculations under Section 4 hereof and this Section 8(a) shall be made to the
nearest cent or to the nearest share, as the case may be.

     (b) Upon the occurrence of each adjustment or readjustment of the
Conversion Price pursuant to Section 4 hereof, the Corporation, at its expense,
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to each holder of shares of Series A
Preferred Stock a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Series A Preferred Stock, use its reasonable best efforts to furnish or cause to
be furnished to such holder a like certificate setting forth (i) such adjustment
or readjustment, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of a share of Series A
Preferred Stock.

9.   Reservation of Stock Issuable Upon Conversion.

     The Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the shares of the Series A Preferred Stock, such
number of its shares of Common Stock that shall from time to time be sufficient
to effect the conversion of all outstanding shares of the Series A Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock not otherwise reserved for issuance shall not be sufficient to effect the
conversion of all then outstanding shares of the Series A Preferred Stock, the
Corporation shall take such corporate action that may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes,
including, without limitation, engaging in best efforts to obtain the requisite
stockholder approval of any necessary amendment to its Certificate of
Incorporation.

10.  Notices.

     Any notice required by the provisions hereof to be given to the holders of
shares of Series A Preferred Stock shall be given in writing and shall be deemed
to have been given (i) in the case of personal or hand delivery, on the date of
such delivery, (ii) in the case of an internationally-recognized overnight
delivery courier, on the second business day after the date when sent, (iii) in
the case of mailing, on the fifth business day following that day on which the
piece of mail containing such communication is posted and (iv) in the case of
facsimile transmission, the date of telephone confirmation of receipt.

11.  Voting Rights.

     Holders of Series A Preferred Stock shall be entitled to vote on all
matters submitted to a vote of the holders of the Corporation's Common Stock,
including with respect to the election of directors of the Corporation, on an as
if converted to Common Stock basis; provided, however, that the number of votes
to which the Series A Preferred Stock is entitled shall be based on a conversion
price of $5.50 per share, giving effect to any future adjustments pursuant to
Section

                                       9.



4(e) above, but without giving any effect to any future adjustments pursuant to
Section 4(f) above.

12.  Protective Provisions.

Subject to the rights of any series of preferred stock that may from time to
time come into existence, so long as any shares of Series A Preferred Stock are
outstanding, the Corporation shall not without first obtaining the approval (by
vote or written consent, as provided by law) of the holders of at least a
majority of the then-outstanding shares of Series A Preferred Stock, voting
separately as a series:

     (a) amend its Certificate of Incorporation (including the filing of a
Certificate of Designations) so as to (i) increase the number of authorized
shares of the Corporation's preferred stock or (ii) affect adversely the shares
of Series A Preferred Stock or any holder thereof, including, without
limitation, by creating any additional series of preferred stock (or issuing
shares under any such series) that is senior or pari passu in liquidation
preference, redemption right, conversion rights or right of payment to the
Series A Preferred Stock;

     (b) after the date of this Certificate of Designation, create any new debt
instrument or create or increase any new or existing bank line (or similar
