                           SYQUEST TECHNOLOGY, INC.


     SyQuest Technology, Inc. (the "Company"), a corporation organized and

existing under the General Corporation Law of the State of Delaware, does hereby

certify that, pursuant to authority conferred on the Board of Directors of the

Company by the Certificate of Incorporation, as amended, of the Company, and

pursuant to Section 151 of the General Corporation Law of the State of Delaware,

the Board of Directors of the Company at a meeting duly held, adopted

resolutions providing for the designations, preferences and relative,

participating, optional or other rights, and the qualifications, limitations or

restrictions thereof, of four hundred thousand (400,000) shares of 5% Cumulative

Convertible Preferred Stock, Series 4, of the Company, as follows:

     RESOLVED, that the Company is authorized to issue 400,000 shares of 5%
Cumulative Convertible Preferred Stock, Series 4, $.001 par value (the "Series 4
Preferred Shares"), which shall have the following powers, designations,
preferences and other special rights:

     1.  Dividends.  The holders of the Series 4 Preferred Shares shall be
         ---------
entitled to a cash dividend of five percent per annum of the Stated Value (as
defined below), on a cumulative basis (prorated for any portion of the
applicable period during which the Series 4 Preferred Shares are outstanding).
Dividends shall accrue from the date of issuance of the Series 4 Preferred
Shares and shall be payable on the last day of each calendar quarter, commencing
June 30, 1997, through and including the date on which the Series 4 Preferred
Shares are converted.  Dividends may be paid at the Company's option in cash or,
on not less than ninety days' notice from the Company to each holder of Series 4
Preferred Shares; in additional Series 4 Preferred Shares, provided that the
Company may not elect to pay dividends in additional Series 4 Preferred Shares
to the extent that the number of authorized and unissued Series 4 Preferred
Shares is insufficient to make such payment or the ability of the holders of the
Series 4 Preferred
<PAGE>
 
Shares to convert Series 4 Preferred Shares or to exercise the Warrant (as
hereinafter defined) is restricted by Section 2(h) below. If the Company elects
to pay to any holder of Series 4 Preferred Shares any such dividend in
additional Series 4 Preferred Shares, the number of such additional Series 4
Preferred Shares shall be determined by dividing the aggregate amount of such
dividend payable to such holder by 100; provided that no fraction of a Series 4
Preferred Share shall be issued, but in lieu thereof, the Company shall pay in
cash an amount equal to such fraction multiplied by $100.

     2.  Conversion of Series 4 Preferred Shares.  The holders of the Series 4
         ---------------------------------------
Preferred Shares shall have the right, at their option, but subject to the terms
of any purchase agreement which the Company may enter into (the "Purchase
Agreement"), to convert the Series 4 Preferred Shares into shares of the common
stock of the Company, $.001 par value, as such stock now exists or may be
changed from time to time hereafter ("Common Stock"), on the following terms and
conditions:

          (a) Conversion Right. Any or all of the Series 4 Preferred Shares
              ----------------
shall be convertible at any time into whole, fully paid and nonassessable shares
of Common Stock, at the conversion price (the "Conversion Price") in effect at
the time of conversion determined as hereinafter provided. Each Series 4
Preferred Share shall have a stated value of $100 (the "Stated Value") for the
purpose of such conversion and the number of shares of Common Stock issuable on
conversion of each Series 4 Preferred Share shall be determined by dividing the
Stated Value thereof by the Conversion Price then in effect. In the event of a
conversion of Series 4 Preferred Shares for which there are accrued and unpaid
dividends, the amount of the accrued and unpaid dividends shall be paid at the
time and in the manner provided in section 1.

          (b) Conversion Price. The Conversion Price shall be the greater of (1)
              ----------------
the arithmetical average of the closing sale prices per share of Common Stock on
the five consecutive trading days preceding the delivery of any Conversion
Notice (as that term is hereinafter defined), as reported by the Nasdaq National
Market (the "NNM"), or, if the NNM is not then the principal trading market for
the Common Stock, on the principal trading market for the Common Stock at that
time, or, if there is then no such principal trading market, the fair market
value per share of Common Stock during such period as determined in good faith
by the Board of Directors of the Company, and (2) ninety percent of such closing
sale price on the day immediately preceding the delivery of the Conversion
Notice (as that term is hereinafter defined); provided that the Conversion Price
shall not be greater than the closing sale price per share of Common Stock as
reported by the NNM on the first day that any Series 4 Preferred Shares are
issued. If the value of the Common Stock is so to be determined by the Board of
Directors of the Company and the holders of the Series 4 Preferred Shares
disagree with said valuation, the value of the Common Stock will be determined
by binding arbitration in accordance with the Commercial Arbitration Rules then
prevailing of the American Arbitration Association, and such arbitration shall
proceed in San Francisco, California, 

                                       2
<PAGE>
 
or at such other place as agreed to in writing by the Company and the holders of
the Series 4 Preferred Shares.

          (c) Adjustment to Conversion Price. In the event that the Company
              ------------------------------
shall declare a dividend or make a distribution on or with respect to the
outstanding shares of its Common Stock in shares of its Common Stock, subdivide
its outstanding shares of Common Stock into a greater number of shares, or
combine its outstanding shares of Common Stock into a smaller number of shares,
then, in each such event, the Conversion Price in effect at the time of the
record date for such dividend or distribution or the effective date of such
subdivision or combination shall be proportionately adjusted, if necessary, as
determined in good faith by the Board of Directors of the Company, so that the
holder of any Series 4 Preferred Shares surrendered for conversion after such
time shall be entitled to receive the aggregate number of shares of Common Stock
that the holder would have owned or been entitled to receive had such Series 4
Preferred Shares been converted immediately prior to such record date or
effective date and the resulting Common Stock had been subject to such dividend,
distribution, subdivision or combination. Such adjustment shall be made
successively whenever any event specified above shall occur.

          (d) Conversion Notice. On presentation and surrender to the Company
              -----------------
(or at any office or agency maintained for the transfer of the Series 4
Preferred Shares) of the certificate(s) ("Preferred Stock Certificate(s)") for
Series 4 Preferred Shares so to be converted, duly endorsed in blank for
transfer or accompanied by proper instruments of assignment or transfer in blank
and written notice of conversion (a "Conversion Notice"), the holder of such
Series 4 Preferred Shares shall be entitled, subject to the limitations herein
contained, to receive in exchange therefor a certificate or certificates for
whole, fully paid and nonassessable shares of Common Stock, which certificates
shall be delivered by the fourth trading day after the date of delivery of the
Conversion Notice and Preferred Stock Certificates for the Series 4 Preferred
Shares being converted, and cash for any fractional share of Common Stock on the
foregoing basis. If the Common Stock can be issued without a restrictive legend
pursuant to the Purchase Agreement, on request made by the holders of the Series
4 Preferred Shares in the Conversion Notice, the Company will authorize and
instruct its transfer agent to issue the Common Stock electronically. The
Conversion Notice shall be deemed delivered and received on the business day
when it is transmitted by facsimile if so transmitted by 5:00 p.m. California
time and the Company receives the Preferred Stock Certificate(s) by 10:00 a.m.
California time the following business day, or on the next business day after it
is deposited for next day delivery with a nationally recognized overnight
delivery service. The Series 4 Preferred Shares shall be deemed to have been
converted, and the person converting the same to have become the holder of 
record of Common Stock, for all purposes as of the date of delivery of the
Conversion Notice.

          (e) Reservation of Shares. The Company shall, as soon as practicable
              ---------------------
hereafter and then for so long as any of the Series 4 Preferred Shares are
outstanding, 

                                       3
<PAGE>
 
reserve and keep available out of its authorized and unissued
Common Stock, solely for the purpose of effecting the conversion of the Series 4
Preferred Shares, such number of shares of Common Stock as shall from time to
time be sufficient to effect the conversion of all of the Series 4 Preferred
Shares then outstanding.

          (f) Fractional Shares. The Company shall not issue any fraction of a
              -----------------
share of Common Stock on any conversion, but shall pay in cash therefor at the
Conversion Price then in effect multiplied by such fraction.

          (g) Taxes. The Company shall pay any and all taxes that may be imposed
              -----
on it with respect to the issuance and delivery of Common Stock on the
conversion of Series 4 Preferred Shares as herein provided. The Company shall
not be required in any event to pay any transfer or other taxes by reason of the
issuance of such Common Stock in names other than those in which the Series 4
Preferred Shares surrendered for conversion are registered on the Company's
records, and no such conversion or issuance of Common Stock shall be made unless
and until the person requesting such issuance shall have paid to the Company the
amount of any such tax, or shall have established to the satisfaction of the
Company and its transfer agent, if any, that such tax has been paid.

          (h) The 19.9% Limit. If at the time that the Company receives a
              ---------------
Conversion Notice, the aggregate number of shares of Common Stock issuable
pursuant to such Conversion Notice and all other Conversion Notices received at
that time (the "Subject Conversion Notices"), when added to the aggregate number
of shares of Common Stock (1) previously issued on conversion of Series 4
Preferred Shares and the exercise of that certain Warrant to purchase Common
Stock (the "Warrant") issued by the Company to Fletcher pursuant to the
Subscription Agreement on the date of initial issuance of the Series 4 Preferred
Shares and (2) issuable on conversion of all remaining outstanding Series 4
Preferred Shares (determining such number as if such Series 4 Preferred Shares
were converted as of the Conversion Date relating to such Conversion Notice) and
(3) issuable on exercise of the Warrant (determined based on the Exercise Price
then in effect, as defined in the Warrant) would exceed nineteen and nine-tenths
percent of the total number of shares of Common Stock outstanding (adjusted to
reflect any split, subdivision, combination or consolidation of the Common
Stock, whether by reclassification, distribution of a dividend with respect to
the outstanding Common Stock payable in shares of Common Stock, or otherwise, or
any recapitalization of the Common Stock) on the date of the first issuance of
Series 4 Preferred Shares (the "19.9% Limit") and such circumstance would
require the approval of the holders of the Common Stock pursuant to the listing
requirements of the Nasdaq Stock Market or the rules of the National Association
of Securities Dealers, Inc. (or such stock exchange or other interdealer
quotation system that is then the Principal Market), the number of Series 4
Preferred Shares identified in the Subject Conversion Notices that, if converted
into shares of Common Stock, would equal or exceed the 19.9% Limit (the "Excess
Preferred Shares"), shall not be converted unless and until the stockholder
approval 

                                       4
<PAGE>
 
referred to in section (2)(j) (the "Stockholder Consent") is obtained or is no
longer required. The Excess Preferred Shares will be allocated among the holders
delivering Subject Conversion Notices on a pro rata basis based on the relative
number of Series 4 Preferred Shares identified in each such Subject Conversion
Notice. Any Excess Preferred shares shall not be converted into shares of Common
Stock until the later of the date on which the Stockholder Consent is obtained
and the Company receives a subsequent Conversion Notice with respect thereto. If
the Company is not otherwise notified by the Nasdaq Stock Market or the National
Association of Securities Dealers, Inc. that Stockholder Consent is necessary,
the Company will issue Common Stock to the holders of the Series 4 Preferred
Shares in excess of the 19.9% Limit.

          (i)  Stockholder Approval.  If there are Excess Preferred Shares as
               --------------------
described in section (2)(i), the Company shall promptly use its best efforts to
obtain the Stockholder Consent, including, without limitation, causing its Board
of Directors to call a special meeting of stockholders and recommend such
approval.

     3.  Voting Rights.  Holders of Series 4 Preferred Shares shall have no
         -------------                                                     
voting rights, except as required by law.

     4.  Liquidation, Dissolution, Winding Up. In the event of any voluntary or
         ------------------------------------
involuntary liquidation, dissolution or winding up of the Company, the holders
of the Series 4 Preferred Shares shall be entitled to receive in cash out of the
assets of the Company, whether from capital or from earnings available for
distribution to its stockholders (the "Preferred Funds"), before any amount
shall be paid to the holders of the Common Stock, an amount equal to the Stated
Value per Preferred Share plus any accrued and unpaid dividends; provided that,
if the Preferred Funds are insufficient to pay the full amount due to the
holders of Series 4 Preferred Shares and holders of shares of other classes or
series of preferred stock of the Company that are of equal rank with the Series
4 Preferred Shares as to payments of Preferred Funds (the "Pari Passu Shares"),
then each holder of Series 4 Preferred Shares and Pari Passu Shares shall
receive a percentage of the Preferred Funds equal to the full amount of
Preferred Funds payable to such holder as a percentage of the full amount of
Preferred Funds payable to all holders of Series 4 Preferred Shares and Pari
Passu Shares. The purchase or redemption by the Company of stock of any class,
in any manner permitted by law, shall not, for the purposes hereof, be regarded
as a liquidation, dissolution or winding up of the Company. Neither the
consolidation or merger of the Company with or into any other corporation or
corporations, nor the sale or transfer by the Company of less than substantially
all of its assets, shall, for the purposes hereof, be deemed to be a
liquidation, dissolution or winding up of the Company. No holder of Series 4
Preferred Shares shall be entitled to receive any amounts with respect thereto
on any liquidation, dissolution or winding up of the Company other than the
amounts provided for herein.

     5.  Preferred Rank.  With respect to preferences as to dividends and
         --------------                                                  
distributions and payments on the liquidation, dissolution or winding up of the
Company, 

                                       5
<PAGE>
 
the Series 4 Preferred Shares shall rank (1) senior to the Common Stock, (2)
with respect to all other existing capital stock of the Company, senior to such
capital stock if permitted by the terms of such capital stock or, if not so
permitted, on a parity with such capital stock if permitted by the terms of such
capital stock or, if not so permitted, junior to such capital stock, and (3)
senior to all series of any class of the Company's capital stock issued after
the date of the filing of this Certificate. So long as any of the Series 4
Preferred Shares are outstanding, no Common Stock and no other capital stock of
the Company ranking junior to the Series 4 Preferred Shares will be redeemed,
purchased or otherwise acquired for any consideration by the Company (except by
conversion into or exchange for stock of the Company ranking junior to the
Series 4 Preferred Shares) unless in each case the Company offers to redeem the
Series 4 Preferred Shares on substantially the same terms (provided that the
redemption price shall not be less than $100 per share). Notwithstanding any
provision hereof to the contrary, the Company may hereafter authorize additional
or other capital stock for issuance to Beijing Legend Group Ltd. and its
affiliates that is senior, equal or junior to the Series 4 Preferred Shares, in
respect of the preferences as to dividends and distributions and payments on the
liquidation, dissolution and winding up of the Company, but the Company may not
otherwise hereafter, for so long as any Series 4 Preferred Shares are
outstanding, authorize additional or other capital stock that is of senior or
equal rank to the Series 4 Preferred Shares, in respect of the preferences as to
dividends and distributions and payments on the liquidation, dissolution and
winding up of the Company. In the event of the merger or consolidation of the
Company with or into another corporation, the Series 4 Preferred Shares shall
maintain their relative powers, designations and preferences provided herein.

     6.  Lost or Stolen Certificates.  On receipt by the Company of evidence of
         ---------------------------                                           
the loss, theft, destruction or mutilation of any Preferred Stock Certificate,
and (in the case of loss, theft or destruction) of any indemnification
undertaking by the holder to the Company that is reasonably satisfactory to the
Company, and on surrender and cancellation of such Preferred Stock Certificate,
if mutilated, the Company shall execute and deliver a new Preferred Stock
Certificate of like tenor and date; provided that the

                                       6
<PAGE>
 
Company shall not be obligated to re-issue any lost, stolen or destroyed
Preferred Stock Certificate if the holder thereof contemporaneously requests the
Company to convert such Series 4 Preferred Shares into Common Stock.

     7.  Amendment.  So long as any Series 4 Preferred Shares are outstanding,
         ---------                                                            
the Company shall not, without first obtaining the approval by vote or written
consent, in the manner provided by law, of the holders of at least a majority of
the total number of Series 4 Preferred shares outstanding, voting separately as
a class, amend or repeal any provision of, or add any provision to, the
Company's Certificate of Incorporation, if such action would alter or change the
preferences, rights, privileges or powers of, or the restrictions provided for
the benefit of, the Series 4 Preferred Shares.

     IN WITNESS WHEREOF, the Company has caused this certificate to be signed by
Henry Montgomery, its Chief Financial Officer, as of April 28, 1997.
