EXHIBIT A

The corporation hereby creates a new series of preferred stock consisting of 1,000,000 shares of its “Series A Convertible Preferred Stock” having the preferences, limitations and relative rights set forth below:

(1) Designation and Rank. The series of Preferred Stock shall be designated the “Series A Convertible Preferred Stock” (“Series A Preferred”) and shall consist of 1,000,000 shares. The Series A Preferred and any other series of Preferred Stock authorized by the Board of Directors of this Corporation are hereinafter referred to as “Preferred Stock” or “Preferred” The Series A Preferred shall be senior to the common stock and all other shares of Preferred Stock that may be later authorized.

(2) Dividend Rate and Rights. The holders of the Series A Preferred shall be entitled to receive Common Stock dividends or other distributions when, as, and if declared by the directors of the Corporation, with the holders of the Common Stock on an as converted basis.

(3) Conversion into Common Stock.

(a) Right to Convert. Each share of Series A Preferred shall be convertible, at the option of the holder thereof, at any time after one year from the date of issuance (the “Conversion Date”) into then (10) shares of fully paid and non-assessable shares of Common Stock (the “Conversion Ratio”).

(b) Mechanics of Conversion. Before any holder shall be entitled to convert, he shall surrender the certificate of certificates representing Series A Preferred to be converted, representing Series A Preferred to be converted, duly endorsed or accompanied by proper instruments of transfer, at the office of the Corporation or of any transfer agent, and shall give written notice to the Corporation at such office that he elects to convert the same. The Corporation shall, as soon as practicable thereafter, issue a certificate or certificates for the number of shares of Common Stock to which the holder shall be entitled. The Corporation shall, as soon as practicable after delivery of such certificates, or such agreement and indemnification in the case of lost, stolen or destroyed certificate, issue and deliver to such holder of Series A Preferred a certificate or certificates for the number of shares of Common Stock to which the such holder is entitled as aforesaid and a check payable to the holder in the amount of any cash amounts payable as a result of the conversion into fractional shares of Common Stock. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series A Preferred to be converted.

(c) Adjustments to Conversion Ratio.

(1) Merger or Reorganization. In case of any consolidation or merger of the Corporation as a result of which holders of Common Stock become entitled to receive other stock or securities or property, or in case of any conveyance of all or substantially all of the assets of the Corporation to another corporation, the Corporation shall mail to each holder of Series A Preferred at least thirty (30) days prior to the consummation of such event a notice thereof, and each such holder shall have the option to either (i) convert such holder’s shares of Series A Preferred into the shares of Common Stock pursuant to this Section3 and thereafter receive the number of shares of stock or other securities or property to which a holder of the number of shares of Common Stock of the Corporation deliverable upon conversion of such Series A Preferred would have been entitled upon such consolidation, merger or conveyance, or (ii) exercise such holder’s rights pursuant to Section 4(a). Unless otherwise set forth by the Board of Directors, the Conversion Ratio shall not be affected by a stock split)-- or stock consolidation by reclassification of the Common Stock. However, once the Series A Preferred has been converted to Common Stock, it shall be subject to all corporate actions that affect or modify the common stock.

	 
	 	 	 
	

	 

 

(d) No Impairment. The Corporation will not, by amendment of the Articles of Incorporation, this Certificate of Designation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue 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 of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred against impairment.

(e) Certificate as to Adjustment. Upon the occurrence of each adjustment or readjustment of the Conversion Ratio of the Series A Preferred pursuant to this Section 3, the Corporation at its expense shall promptly compute each adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series A Preferred a certificate setting forth such adjustment or readjustment and the calculation on which such adjustment or readjustment is based. The Corporation shall, upon written request at any time of any holder of Series A Preferred, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversation Ratio for the Series A Preferred 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 the Series A Preferred.

(f) Notices of Record Date. In the event of any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarter) or other distribution, the Corporation shall mail to each holder of Series A Preferred at least ten (10) days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution.

	 
	 	2	 
	

	 

 

(g) Common Stock Reserved. The Corporation shall reserve and keep available out of its authorized but unissued Common Stock such number of shares of Common Stock as shall from time to time be sufficient to effect conversion of the Series A Preferred.

 

(4) Liquidation Preference. (a) In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary (a “Liquidation”), the assets of the Corporation available for distribution to its stockholders shall be distributed as follows:

(1) The holders of the Series A Preferred shall be entitled to receive, prior to the holders of the other series of Preferred Stock and prior and in preference to any distribution of the assets or surplus funds of the Corporation to the holders of any other shares of stock of the corporation by reason of their ownership of such stock, an amount equal to $1.00 per share with respect to each share of Series A Preferred, plus all declared but unpaid dividends with respect to such share.

(2) If upon occurrence of a Liquidation the assets and funds thus distributed among the holders of the Series A Preferred shall be insufficient to permit the payment to such holders of the full preferential amount, then the entire assets and funds of the Corporation legally available for distribution shall be distributed among the holders of the Series A Preferred ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

(3) After payment of the full amounts to the holders of Series A Preferred as set forth above in paragraph (1), any remaining assets of the Corporation shall be distributed pro rata to the holders of the Preferred Stock and Common Stock (in the case of the Preferred Stock, on as “as converted” basis into Common Stock).

(b) For purposes of this Section 4, and unless a majority of the holders of the Series A Preferred affirmatively vote or agree by written consent to the contrary, a Liquidation shall be deemed to include (i) the acquisition of the Corporation by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) and (ii) a sale of all or substantially all of the assets of the Corporation, unless the Corporation’s stockholders of record as constituted immediately prior to such acquisition or sale will, immediately after such acquisition or sale (by virtue of securities issued as consideration for the Corporation’s acquisition or sale or otherwise) hold at least fifty perfect (50%) of the voting power of the surviving or acquiring entity. 

(c) If any of the assets of the Corporation are to be distributed other than in cash under this Section 4, then the board of directors of the Corporation shall promptly engage independent competent appraisers to determine the value of the assets to be distributed to the holders of Preferred Stock or Common Stock. The Corporation shall, upon receipt of such appraiser’s valuation, give prompt written notice to each holder of shares of Preferred Stock or Common Stock of the appraiser’s valuation.

	 
	 	3	 
	

	 

 

(5) Voting Rights. Except as otherwise required by law, the holders of Series A Preferred and the holders of Common Stock shall be entitled to notice of any stockholders’ meeting and to vote as a single class upon and matter submitted to the stockholders for a vote as follows: (i) the holders of each series of Preferred Stock shall have one vote for each full share of Common Stock into which a share of such series would be convertible on the record date for the vote, or, if no such record date is established, at the date such vote is taken or any written consent of stockholders is solicited; and (ii) the holders of Common Stock shall have one vote per share of Common Stock held as of such date.

(6) Covenants. (a) In addition to any other rights provided by law, the Corporation shall not, without first obtaining the affirmative vote or written consent of the holders of a majority of the outstanding shares or Series A Preferred, do any of the following:

(1) Take any action which would either alter, change or affect the rights, preferences, privileges or restrictions of the Series A Preferred or increase the number of shares of such series authorized hereby or designate any other series of Preferred Stock;

(2) increase the size of ant equity incentive plan(s) or arrangements;

(3) make fundamental changes to the business of the Corporation;

(5) create any new class of shares having preferences over or being on a parity with the Series A Preferred as to dividends or assets, unless the purpose of creation of such class is, and the proceeds to be derived from the sale and issuance thereof are to be used for, the retirement of all Series A Preferred the outstanding;

(6) accrue any indebtedness in excess of $1,000,000;

(7) make any change in the size or number of authorized directors;

(8) repurchase any of the Corporation’s Common Stock;

covered by such registration statement);

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus(es) used in
connection therewith as may be necessary to keep such registration statement
effective for a period of not less than one (1) year or such shorter period
until such Registrable Shares are no longer Registrable Shares and comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

                  (c) furnish to each seller of Registrable Shares such number

the prospectus(es) included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Shares owned
by such seller;

                  (d) use its reasonable best efforts to register or qualify
such Registrable Shares under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable Shares
owned by such seller (provided that Tegal will not be required to (i) qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subparagraph or (ii) consent to general service
of process in any such jurisdiction);

                  (e) notify each seller of such Registrable Shares, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, Tegal will prepare a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Shares, such prospectus will not contain any
untrue statement of a material fact or omit to state any fact necessary to make
the statements therein not misleading;

                  (f) cause all such Registrable Shares to be listed on each
securities exchange on which similar securities issued by Tegal are then listed
or if no such securities are then listed, such securities exchange as the
holders of a majority of the Registrable Shares included in such registration
may reasonably request;
<PAGE>

                  (g) make available for inspection by any seller of Registrable
Shares and any attorney, accountant or other agent retained by any such seller,
all financial and other records, pertinent corporate documents and properties of
Tegal, and cause Tegal's officers, directors, employees and independent
accountants to supply all information reasonably requested by any such seller,
attorney, accountant or agent in connection with such registration statement;
and

                  (h) advise each seller of such Registrable Shares, promptly
after it shall receive notice or obtain knowledge thereof, of the issuance of
any stop order by the SEC suspending the effectiveness of such registration
statement or the initiation or threatening of any proceeding for such purpose
and promptly use all reasonable efforts to prevent the issuance of any stop
order or to obtain its withdrawal if such stop order should be issued.

      4. Registration Expenses. All expenses incident to Tegal's performance of
or compliance with this Agreement, including, but not limited to, all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws, printing expenses, messenger and delivery expenses, and fees and
disbursements of counsel for Tegal and all independent certified public
accountants and other Persons retained by Tegal (all such expenses being herein
called "Registration Expenses"), will be borne by Tegal, provided that Tegal
shall not be required to pay sales commissions, discounts or transfer taxes. In
addition, Tegal will pay its internal expenses (including, but not limited to,
all salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit or quarterly review, the
expense of any liability insurance obtained by Tegal and the expenses and fees
for listing the securities to be registered on each securities exchange.

      5. Indemnification.

            5.1 By Tegal. Tegal agrees to indemnify, to the extent permitted by
law, each holder of Registrable Shares, its officers, employees and directors
and each Person who controls such holder (within the meaning of the Securities
Act) against all losses, claims, damages, liabilities and expenses (including,
but not limited to, attorneys' fees and expenses) caused by any untrue or
alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus, or any amendment thereof or
supplement thereto, or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are caused by or contained in any
information furnished in writing to Tegal by such holder expressly for use
therein or by such holder's failure to deliver a copy of the prospectus or any
amendments or supplements thereto after Tegal has furnished such holder with a
sufficient number of copies of the same. The payments required by this Section
5.1 will be made periodically during the course of the investigation or defense,
as and when bills are received or expenses incurred.

            5.2 By Each Holder. In connection with any registration statement in
which a holder of Registrable Shares is participating, each such holder will
furnish to Tegal in writing such information as Tegal reasonably requests for
use in connection with any such registration statement or prospectus and, to the
extent permitted by law, will indemnify Tegal, its directors, employees and
officers and each Person who controls Tegal (within the meaning of the
Securities Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement of material fact contained
in the registration statement, prospectus or preliminary prospectus, or any
amendment thereof or supplement thereto, or any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in or omitted from any information so
furnished in writing by such holder for the acknowledged purpose of inclusion in
such registration statement, prospectus or preliminary prospectus; provided that
the obligation to indemnify will be several, not joint and several, among such
holders of Registrable Shares and the liability of each such holder of
Registrable Shares will be in proportion to and limited in all events to the net
amount received by such holder from the sale of Registrable Shares pursuant to
such registration statement.
<PAGE>

            5.3 Procedure. Any Person entitled to indemnification hereunder will
(a) give prompt written notice to the indemnifying Person of any claim with
respect to which it seeks indemnification and (b) unless in such indemnified
Person's reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying Person to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified Person. If such defense is assumed, the
indemnifying Person will not be subject to any liability for any settlement made
by the indemnified Person without its consent (but such consent will not be
unreasonably withheld). An indemnifying Person who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying Person with respect to such claim, unless in the reasonable
judgment of any indemnified Person a conflict of interest may exist between such
indemnified Person and any other of such indemnified parties with respect to
such claim.

            5.4 Survival. The indemnification provided for under this Agreement
will remain in full force and effect regardless of any investigation made by or
on behalf of the indemnified Person or any officer, director or controlling
Person of such indemnified Person and will survive the transfer of securities.
Tegal also agrees to make such provisions as are reasonably requested by any
indemnified Person for contribution to such Person in the event Tegal's
indemnification is unavailable for any reason.

      6. Compliance with Rule 144 and Rule 144A. So long as Tegal files reports
under Section 13 or 15(d) of the Exchange Act, then at the request of any holder
of Registrable Shares who proposes to sell securities in compliance with Rule
144 of the Securities Act, Tegal will (a) forthwith furnish to such holder a
written statement of compliance with the filing requirements of the Securities
Act as set forth in Rule 144, as such rule may be amended from time to time and
(b) make available to the public and such holders such information as will
enable the holders of Registrable Shares to make sales pursuant to Rule 144. At
any time that Tegal is not subject to Section 13 or 15(d) of the Exchange Act,
Tegal will provide to the holder of Registrable Shares and to any prospective
purchaser of Registrable Shares under Rule 144A of the Securities Act, the
information described in Rule 144A(d)(4) of the Securities Act.
<PAGE>

      7. Miscellaneous.

            7.1 No Inconsistent Agreements. Tegal will not hereafter enter into
any agreement with respect to its securities which is inconsistent with or which
otherwise materially limits, restricts or interferes with the rights granted to
the holders of Registrable Shares in this Agreement.

            7.2 Amendments and Waivers. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended or waived at any time

and shareholders, in which case FDSI need not approve the amendment or waiver);
provided, however, that the provisions of this Agreement may not be amended or
waived without the consent of the holders of all the Registrable Shares
adversely affected by such amendment or waiver if such amendment or waiver
adversely affects a portion of the Registrable Shares but does not so adversely
affect all of the Registrable Shares. Any waiver, permit, consent or approval of
any kind or character on the part of any such holders of any provision or
condition of this Agreement must be made in writing and shall be effective only
to the extent specifically set forth in writing. Any amendment or waiver
effected in accordance with this paragraph shall be binding upon each holder of
Registrable Shares and Tegal.

            7.3 Successors and Assigns. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto will bind and inure to the benefit of the
respective successors and assigns of the parties hereto, whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for the benefit of FDSI, the shareholders
of FDSI or holders of Registrable Shares are also for the benefit of, and
enforceable by, any subsequent holders of such Registrable Shares.

            7.4 Descriptive Headings. The descriptive headings of this Agreement
are inserted for convenience of reference only and do not constitute a part of
and shall not be utilized in interpreting this Agreement.

            7.5 Notices. Any notices required or permitted to be sent hereunder
shall be delivered personally or mailed, certified mail, return receipt
requested, or delivered by overnight courier service to the following addresses,
or such other address as any party hereto designates by written notice to Tegal,
