Item 5.  Other Events.

Transactions with Commodore Environmental Services, Inc.

      On March 5, 1998, Lanxide Corporation ("Lanxide") entered into a
series of transactions with Commodore Environmental Services, Inc.
("Commodore") and certain of its subsidiaries pursuant to which, among
other things, Commodore paid $500,000 cash and its subsidiaries agreed to
cancel $4,500,000 in indebtedness to subsidiaries of Lanxide (which was
guaranteed by Lanxide) in exchange for the issuance of a royalty-bearing
license to use CERASET(TM) on a worldwide basis, excluding Japan (the
"License"). The License, which was issued pursuant to the terms of a
Settlement and Release Agreement (the "Release Agreement"), grants
Commodore certain business and technology rights that do not conflict with
the rights of Lanxide's other licenses or future licenses in the fields for
metal matrix composites and ceramic matrix composites.

      In connection with the issuance of the License, Lanxide and Commodore
amended the Securities Purchase Agreement, dated July 3, 1997 (the
"Purchase Agreement" and, as amended, the "Amended Purchase Agreement").
Pursuant to the Amended Purchase Agreement, among other things, (i) Lanxide
and Commodore each agreed to exchange all of the issued and outstanding
shares of Series G Preferred Stock of Lanxide ("Series G Preferred Stock"),
which are held by Commodore, for an equal number of Series H Preferred
Stock of Lanxide (the "Series H Preferred Stock"), (ii) Commodore's right
to purchase additional shares of Series G Preferred Stock pursuant to the
terms of the original Purchase Agreement was cancelled; (iii) Lanxide
issued a Warrant (the "Warrant") to Commodore for the purchase of up to
270,000 shares of Lanxide's common stock, at an exercise price of $7.41 per
share; and (iv) Commodore's right to purchase 250,000 shares of Series F
Preferred Stock of Lanxide ("Series F Preferred Stock") pursuant to a
Warrant issued to Commodore on July, 3, 1997 (the "1997 Warrant") was
cancelled.

      The above description of the transactions contemplated set forth
above is only a summary and is qualified in its entirety by reference to
the full text of the Release Agreement, the Amended Purchase Agreement, the
Warrant and the Certificate of Stock Designation of the Series H Preferred
Stock, which are attached hereto and incorporated by reference herein.
Reference is also made to Lanxide's Current Report on Form 8-K, filed on
July 18, 1997, and the exhibits thereto, for a description of the Purchase
Agreement, the Series F Preferred Stock, the Series G Preferred Stock and
the 1997 Warrant.

Authorization of Employee Stock Option Plan.

      In connection with the restructuring of Lanxide's operations,
Lanxide's Board of Directors authorized the adoption of a stock option plan
(the "Option Plan") pursuant to which certain employees of Lanxide will be
granted five year options to acquire shares of common stock of Lanxide for
an exercise price anticipated to be $1.00. The aggregate number of shares
to be reserved for issuance under the Option Plan will not exceed
twenty-five percent (25%) of the issued and outstanding shares of common
stock of Lanxide as of March 5, 1998, on a fully diluted basis.

Appointment of Director

      On March 5, 1998, Michael J. Hollins was elected to fill a vacancy on
Lanxide's Board of Directors and to serve as Vice President - Operations of
Lanxide.

Recommencement of Operations

      Lanxide announced in a press release issued on March 6, 1998, that
although it has commenced limited operations with reduced debt and some
limited working capital, Lanxide continues to work on additional
restructuring measures necessary to improve its working capital position.

                 AMENDMENT TO SECURITIES PURCHASE AGREEMENT


            This Amended Securities Purchase Agreement (this "Agreement")
is entered into this 5th day of March, 1998, by and between LANXIDE
CORPORATION, a Delaware corporation ("Lanxide") and COMMODORE ENVIRONMENTAL

                                 RECITALS:

            WHEREAS, Lanxide's subsidiary, Lanxide Performance, is a party

as the "Lanxide Performance $1.5 Million Loan Documents");

            WHEREAS, Lanxide and COES are parties to a Securities Purchase

into a "Voting Agreement" with Bentley J. Blum ("Blum"), Paul E. Hannesson
("Hannesson"), David Mitchell ("Mitchell"), Herbert Cohen ("Cohen") and
Kenneth Adelman ("Adelman") (collectively the "Proxy Holders") pursuant to

            NOW, THEREFORE, in consideration of the foregoing Recitals and
other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, and intending to be legally bound, it is hereby
agreed as follows:

            1.          Definitions.  "Common Stock Warrant" shall
                  mean the three (3) year warrant issued to COES on the
                  execution and delivery date hereof entitling the
                  holder to purchase up to 270,000 shares of Lanxide
                  common stock, at an exercise price of $7.41 per
                  warrant share, in substantially the form of Exhibit
                  "A" annexed hereto.

            2.          Cancellation of Share Purchase Right.  The
                  parties hereto acknowledge and agree that COES's
                  right to purchase any additional shares of Series G
                  Preferred Stock of Lanxide (the "Series G Preferred
                  Stock"), as provided in Section 2.2(c) and (d) of the
                  Securities Purchase Agreement is hereby cancelled.

            3.          Cancellation of Warrant.  The parties hereto
                  hereby agree that the Warrant which Lanxide issued to
                  COES for the right to purchase any shares of
                  preferred stock, as set forth in Section 2.3 of the
                  Securities Purchase Agreement, is hereby cancelled.

            4.          Board Action for Series F Preferred Stock;
                  Consent to Employee Stock Option Plan; Consent to
                  Landlord Warrant Modifications. Lanxide hereby
                  covenants and agrees not to issue any shares of
                  Series F Preferred Stock and shall take all necessary
                  action as soon as practicable to cancel all Series F
                  Preferred Stock, and COES hereby consents to such
                  cancellation.

            COES hereby consents to the adoption by Lanxide of a stock
option plan anticipated to be approved by Lanxide on or before March 31,
1998 (i) pursuant to which certain employees of Lanxide will be given five
year options to acquire shares of Common Stock for an exercise price
anticipated to be $1.00 per share and (ii) under which the aggregate number
of shares to be reserved for issuance is not to exceed twenty-five percent
(25%) of the issued and outstanding shares of Common Stock as of the date
hereof on a fully diluted basis, including shares of Common Stock issuable
under the Common Stock Warrant.

            COES hereby consents to Lanxide's modifications to an
outstanding Warrant to acquire shares of Common Stock registered in the
name of W.P. Carey & Co., Inc., or an affiliate thereof, which entity is
Lanxide's landlord for its principal place of business, provided that such
modifications do not (i) reduce the exercise price under such modified
Warrant below $1.00 per share of Common Stock issuable upon exercise of
such Warrant or (ii) increase the maximum number of shares of Common Stock
issuable upon a exercise of such modified Warrant to a number that is
greater than 31,000 shares.

            5.          Post-Closing Financing and Consummation. 
                  The parties hereto hereby acknowledge and agree that
                  COES's duty to seek or obtain post-closing financing
                  and/or to consummate any of the transactions
                  contemplated in the Securities Purchase Agreement
                  not already consummated prior to the execution date
                  hereof are hereby cancelled.

            6.          Exchange of Shares of Series G Preferred 
                  Stock; Board Action for Series G Preferred Stock;
                  Common Stock Warrant. Lanxide, in consideration for
                  (a) the terms and conditions of this Agreement, (b)
                  other good and valuable consideration, the receipt
                  and sufficiency of which are hereby acknowledged,
                  shall (i) upon surrender to Lanxide of the share
                  certificates representing COES' ownership of all
                  shares of Series G Preferred Stock, issue share
                  certificate(s), in such denominations and registered
                  in such names as COES may reasonably request,
                  representing ownership of a like number of shares of
                  Lanxide's Preferred Stock, Series H, having terms
                  and conditions set forth on Exhibit B hereto (the
                  "Series H Preferred Stock"), (ii) following COES'
                  surrender of the certificates representing its
                  ownership of Series G Preferred Stock, cause its
                  Board to cancel all Series G Preferred Stock, and
                  COES hereby consents to such cancellation; and (iii)
                  issue to COES (in such denominations as may
                  reasonably be requested by COES) the Common Stock
                  Warrant.

            7.          Registration Rights.  The following
                  provisions replace the provisions set forth in
                  Section 11 of the Securities Purchase Agreement:

            7.1 Piggyback Rights. If at any time following the date hereof,
Lanxide shall file a registration statement (other than a registration
statement on Form S-4, Form S-8, or any successor form) with the SEC while
any Registrable Securities (as hereinafter defined) are outstanding,
Lanxide shall give all the then holders of any Registrable Securities or
securities which are convertible into or exercisable for Registrable
Securities, including for this purpose, holders of the Registrable
Securities (the "Eligible Holders") at least 30 days prior written notice
of the filing of such registration statement. If requested by any Eligible
Holder in writing within 15 days after receipt of any such notice, Lanxide
shall, at Lanxide's sole expense (other than the fees and disbursements of
counsel for the Eligible Holders and the underwriting discounts or
commissions, if any, payable in respect of the Registrable Securities sold
by any Eligible Holder), register or qualify all or, at each Eligible
Holder's option, any portion of the Registrable Securities of any Eligible
Holders who shall have made such request, concurrently with the
registration of such other securities, all to the extent requisite to
permit the public offering and sale of the Registrable Securities through
the facilities of all appropriate securities exchanges and the
over-the-counter market, and will use its best efforts through its
officers, directors, auditors, and counsel to cause such registration
statement to become effective as promptly as practicable. Notwithstanding
the foregoing, if the managing underwriter of any such offering shall
advise Lanxide in writing that, in its opinion, the distribution of all or
a portion of the Registrable Securities requested to be included in the
registration concurrently with the securities being registered by Lanxide
would adversely affect the distribution of such securities by Lanxide for
its own account, then the underwriters shall have the right to exclude any
or all of the securities that the Eligible Holders or other prospective
seller requested to be included in such public offering; provided, however,
that such exclusion shall be made pro rata among the Eligible Holders and
the other stockholders of Lanxide that have registration rights or have
otherwise requested to participate on a piggyback basis in such public
offering in proportion to the respective number of shares of securities
which were requested to be included in such public offering. As used
herein, "Registrable Securities" shall mean the shares of Lanxide Common
Stock issuable upon full or partial exercise of the Warrant, which have not
been previously sold pursuant to a registration statement or Rule 144
promulgated under the 1933 Act.

            7.2  If at any time following COES's completion of its purchase
and payment for any of the 270,000 Shares of Common Stock, Lanxide shall
receive a written request, from Eligible Holders who in the aggregate own
(or upon exercise of all Warrants then outstanding or issuable would own)
at least 50% of the Registrable Securities then included (or upon such
exercises would be included) in the Registrable Securities (the "Majority
Holders"), to register the sale of all or part of such Registrable
Securities, Lanxide shall, as soon as reasonably practicable, but in any
event within 180 days of Lanxide's receipt of a written request from the
Eligible Holders, prepare and file with the SEC a registration statement
sufficient to permit the public offering and sale of the Registrable
Securities through the facilities of all appropriate securities exchanges
and the over-the-counter market, and will use its best efforts through its
officers, directors, auditors and counsel to cause such registration
statement to become effective within such 180 day time period; provided,
however, that the Eligible Holders shall bear all expenses, fees (including
Lanxide's reasonable attorney's fees) and disbursements incurred in
connection with such registration. Lanxide shall not be obligated to effect
any registration of its securities pursuant to this Section 7.2 within six
months after the effective date of a previous registration statement
prepared and filed in accordance with Sections 7.1 or 7.2. Within seven (7)
business days after receiving any request contemplated by this Section 7.2,
Lanxide shall give written notice to all the other Eligible Holders,
advising each of them that Lanxide is proceeding with such registration and
offering to include therein all or any portion of any such other Eligible
Holder's Registrable Securities, provided that Lanxide receives a written
request to do so from such Eligible Holder within fifteen (15) days after
receipt by him or it of Lanxide's notice. Provided, however, that the
Eligible Holders may not make such a request or demand provided for in this
Section 7.2 before January 1, 2000.

            7.3 Blue Sky Matters. In the event of a registration pursuant
to the provisions of this Section 7, Lanxide shall use its best efforts to
cause the Registrable Securities so registered to be registered or
qualified for sale under the securities or blue sky laws of such
jurisdictions as the Eligible Holder or such holders may reasonably
request; provided, however, that Lanxide shall not be required to qualify
to do business in any state by reason of this Section 7.3 in which it is
not otherwise required to qualify to do business.

            7.4 Period During Which Registration Statement to Remain
Effective. Lanxide shall keep effective any registration or qualification
contemplated by this Section 7 and shall from time to time amend or
supplement each applicable registration statement, preliminary prospectus,
final prospectus, application, document, and communication for such period
of time as shall be required to permit the Eligible Holders to complete the
offer and sale of the Registrable Securities covered thereby. Lanxide shall
in no event be required to keep any such registration or qualification in
effect for a period in excess of nine months from the date on which the
Eligible Holders are first free to sell such Registrable Securities;
provided, however, that, if Lanxide is required to keep any such
registration or qualification in effect with respect to securities other
than the Registrable Securities beyond such period, Lanxide shall keep such
registration or qualification in effect as it relates to the Registrable
Securities for so long as such registration or qualification remains or is
required to remain in effect in respect of such other securities.

            7.5 Copies of Documents. In the event of a registration
pursuant to the provisions of this Section 7, Lanxide shall furnish to each
Eligible Holder such number of copies of the registration statement and of
each amendment and supplement thereto (in each case, including all
exhibits), such reasonable number of copies of each prospectus contained in
such registration statement and each supplement or amendment thereto
(including each preliminary prospectus), all of which shall conform to the
requirements of the 1933 Act and the rules and regulations thereunder, and
such other documents, as any Eligible Holder may reasonably request to
facilitate the disposition of the Registrable Securities included in such
registration.

            7.6 Opinion of Counsel to Lanxide. In the event of a
registration pursuant to the provisions of this Section 7, Lanxide shall
furnish each Eligible Holder of any Registrable Securities so registered
with an opinion of its counsel (reasonably acceptable to the Eligible
Holders) to the general effect that (i) the registration statement has
become effective under the 1933 Act and no order suspending the
effectiveness of the registration statement, preventing or suspending the
use of the registration statement, any preliminary prospectus, any final
prospectus, or any amendment or supplement thereto has been issued nor has
the SEC or any securities or blue sky authority of any jurisdiction
instituted or threatened to institute any proceedings with respect to such
an order, (ii) the registration statement and each prospectus forming a
part thereof (including each preliminary prospectus), and any amendment or
supplement thereto, complies as to form with the 1933 Act and the rules and
regulations thereunder, and (iii) such counsel has no knowledge of any
material misstatement or omission in such registration statement or any
prospectus, as amended or supplemented.

            7.7 Terms of Underwriting Agreement. In the event of a
registration pursuant to the provision of this Section 7, Lanxide shall
enter into a cross-indemnity agreement and a contribution agreement, each
in customary form, with each underwriter, if any, and, if requested, enter
into an underwriting agreement containing conventional representations,
warranties, allocation of expenses, and customary closing conditions,
including, but not limited to, opinions of counsel and accountants' cold
comfort letters, with any underwriter who acquires any Registrable
Securities.

            7.8 Undertakings of Eligible Holders. In the event of a
registration pursuant to the provisions of this Section 7:

                  (a) each Eligible Holder shall furnish to Lanxide in
            writing such appropriate information (relating to such Eligible
            Holder and the intention of such Eligible Holder as to proposed
            methods of sale or other disposition of their Shares) and the
            identity of and compensation to be paid to any proposed
            underwriters to be employed in connection therewith as Lanxide,
            any underwriter, or the SEC or any other regulatory authority
            may request;

                  (b) the Eligible Holders shall enter into the usual and
            customary form of underwriting agreement agreed to by Lanxide
            and any underwriter with respect to any such offering, if
            required, and such underwriting agreement shall contain the
            customary rights of indemnity between Lanxide, the
            underwriters, and such Eligible Holders;

                  (c) each Eligible Holder shall agree that he shall
            execute, deliver and/or file with or supply Lanxide, any
            underwriters, the SEC and/or any state or other regulatory

                  (e) in the event that all the Registrable Securities have
            not been sold on or prior to the expiration of the period

            Lanxide which must be accompanied by such prospectus, (ii)
            return all such prospectuses in such Eligible Holder's hands to
            Lanxide, and (iii) not offer or sell any securities of Lanxide

            and Lanxide has given such Eligible Holder notification
            permitting such Eligible Holder to resume offers and sales.

            7.9 Covenant Regarding Current Information. Lanxide agrees that
until all the Registrable Securities have been sold under a registration
statement or pursuant to Rule 144 under the 1933 Act, it shall use its best
efforts to keep current in filing all reports, statements and other
materials required to be filed with the SEC to permit holders of the
Registrable Securities to sell such securities under Rule 144.

                              EXHIBIT "A"


      NEITHER THE WARRANTS REPRESENTED BY THIS CERTIFICATE NOR THE
      SHARES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED. NEITHER THE WARRANTS NOR
      SUCH SHARES MAY BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT, OR AN EXEMP
      TION FROM REGISTRATION UNDER SUCH ACT.

                          LANXIDE CORPORATION

         WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

No. ___
                                                        270,000 Shares


      THIS CERTIFIES that, for value received, Commodore Environmental
Services, Inc. (the "Holder"), is entitled to subscribe for and purchase
from Lanxide Corporation, a Delaware corporation (the "Company"), upon the
terms and conditions set forth herein, at any time and from time to time
after December 31, 1998 and before 5:00 P.M. (New York City time) on March
1, 2001, New York time (the "Exercise Period"), Two Hundred and Seventy
Thousand (270,000) shares of common stock, par value .01 per share, of the
Company (the "Common Stock"), at an exercise price of $7.41 per share (the
"Exercise Price"). This Warrant is issued in connection with the sale to
the Holder of 20,000 shares of the Company's non-voting, non-convertible
Series G Preferred Stock, $.01 par value per share, of the Company (the
"Series G Preferred Stock") pursuant to a Securities Purchase Agreement,
dated July 3, 1997 (the "Securities Purchase Agreement"), as amended by an
Amendment to Securities Purchase Agreement dated March 5, 1998 (the
"Amendment"), by and between the Holder and the Company, the sale of which
has already occurred. In accordance with the Amendment, the Company and the
Holder have exchanged all of the shares of Series G Preferred Stock
purchased by the Holder pursuant to the Securities Purchase Agreement for a
like number of shares of the Company's Preferred Stock, Series H (the
"Series H Preferred Stock"). This Warrant is issued in substitution of the
Warrant issued on July 3, 1997 which July 3, 1997 Warrant has been
cancelled. As used herein the term "this Warrant" shall mean and include
this Warrant and any Warrant or Warrants hereafter issued as a consequence
of the exercise or transfer of this Warrant in whole or in part.

      The number of shares of Common Stock issuable upon exercise of the
Warrants (the "Warrant Shares") and the Exercise Price may be adjusted from
time to time as hereinafter set forth.

      1.          This Warrant may be exercised during the Exercise
            Period, as to the whole or any lesser number of the respective
            whole Warrant Shares, by the surrender of this Warrant (with
            the election at the end hereof duly executed) to the Company at
            its office as set forth in the form of election attached
            hereto, or at such other place as is designated in writing by
            the Company, together with a certified or bank cashier's check
            payable to the order of the Company in an amount equal to the
            Exercise Price multi plied by the number of respective Warrant
            Shares for which this Warrant is being exercised.
            Notwithstanding the foregoing, or any other provision of this
            Warrant to the contrary, to the extent that the Holder shall
            have acquired shares of Series H Preferred Stock of the
            Company, this Warrant may be exercised by the Holder during the
            Exercise Period and the Exercise Price for one or more Warrant
            Shares may be paid by the Holder's surrender for cancellation
            of one or more shares of Series H Preferred Stock. Upon such
            Holder's delivery of such share(s) of Series H Preferred Stock,
            duly endorsed in blank for transfer, the Company shall
            simultaneously deliver to the Holder of this Warrant that
            number of Warrant Shares equal to the quotient obtained by
            dividing (a) the product of (i) the number of shares of Series
            H Preferred Stock so surrendered for cancellation and (ii)
            $100.00 by (b) $7.41. Upon issuance of such Warrant Shares, the
            Corporation shall cancel the shares of Series H Preferred Stock
            so surrendered by the Holder. In the event and to the extent
            that all shares of Series H Preferred Stock acquired by the
            Holder pursuant to the Amendment shall have been so surrendered
            for cancellation and Warrant Shares issued therefor, the
            Exercise Price for all remaining Warrant Shares issuable
            pursuant to this Warrant shall be paid in accordance with the
            first sentence of this Section 1.

      2.          Upon each exercise of the Holder's rights to
            purchase Warrant Shares and payment of the Exercise Price, the
            Holder shall be deemed to be the holder of record of the
            Warrant Shares issuable upon such exercise, notwithstanding
            that the transfer books of the Company shall then be closed or
            certificates representing such Warrant Shares shall not then
            have been actually delivered to the Holder. As soon as
            practicable after each such exercise of this Warrant and
            payment by the Holder, the Company shall issue and cause to be
            delivered a certificate or certificates for the Warrant Shares
            issuable upon such exercise, registered in the name of the
            Holder or its designee. If the Warrant should be exercised in
            part only, the Company shall, upon surrender of this Warrant
            for cancellation, execute and deliver a new Warrant evidencing
            the right of the Holder to purchase the balance of the Warrant
            Shares (or portions thereof) subject to purchase hereunder.

      3.          Any Warrants issued upon the transfer or exercise
            in part of this Warrant shall be numbered and shall be
            registered in a Warrant Register as they are issued. The
            Company shall be entitled to treat the registered holder of any
            Warrant on the Warrant Register as the Owner in fact thereof
            for all purposes and shall not be bound to recognize any
            equitable or other claim to or interest in such Warrant on the
            part of any other person, and shall not be liable for any
            registration or transfer of Warrants which are registered or to
            be registered in the name of a fiduciary or the nominee of a
            fiduciary unless made with the actual knowledge that a
            fiduciary or nominee is committing a breach of trust in
            requesting such registration or transfer, or with the knowledge
            of such facts that its participation therein amounts to bad
            faith. This Warrant shall be transferable only on the books of
            the Company upon delivery thereof duly endorsed by the Holder
            or by his duly authorized attorney or representative, or
            accompanied by proper evidence of succession, assignment, or
            authority to transfer. In all cases of transfer by an attorney,
            executor, administrator, guardian, or other legal
            representative, duly authenticated evidence of his or its
            authority shall be produced. Upon any registration of transfer,
            the Company shall deliver a new Warrant or Warrants to the
            person entitled thereto. This Warrant may be exchanged, at the
            option of the Holder thereof, for another Warrant, or other
            Warrants of different denominations, of like tenor and
            representing in the aggregate the right to purchase a like
            number of Warrant Shares (or portions thereof), upon surrender
            to the Company or its duly authorized agent. Notwithstanding
            the foregoing, the Company shall have no obligation to cause
            Warrants to be transferred on its books to any person if, in
            the opinion of counsel to the Company, such transfer does not
            comply with the provisions of the Securities Act of 1933, as
            amended (the "Act"), and the rules and regulations
            promulgated thereunder.

      4.          The Company shall at all times reserve and keep
            available out of its authorized and unissued Common Stock,
            solely for the purpose of providing for the exercise of the
            rights to purchase all Warrant Shares granted pursuant to the
            Warrants, such number of shares of Common Stock as shall, from
            time to time, be sufficient therefor. The Company covenants
            that all shares of Common Stock issuable upon exercise of this
            Warrant, upon receipt by the Company of the full Exercise Price
            therefor, shall be validly issued, fully paid, nonassessable,
            and free of preemptive rights.

      5.          (a) In case the Company shall at any time after
            the date the Warrants were first issued (i) declare a dividend
            on the outstanding Common Stock payable in shares of its
            capital stock, (ii) subdivide the outstanding Common Stock,
            (iii) combine the outstanding Common Stock into a smaller
            number of shares, or (iv) issue any shares of its capital stock
            by reclassification of the Common Stock (including any such
            reclassification in connection with a consolidation or merger
            in which the Company is the continuing corporation), then, in
            each case, the Exercise Price, and the number of Warrant Shares
            issuable upon exercise of this Warrant, in effect at the time
            of the record date for such dividend or of the effective date
            of such subdivision, combination, or reclassification, shall be
            proportionately adjusted so that the Holder after such time
            shall be entitled to receive the aggregate number and kind of
            shares which, if such Warrant had been exercised immediately
            prior to such time, he or it would have owned upon such
            exercise and been entitled to receive by virtue of such
            dividend, subdivision, combination, or reclassification. Such
            adjustment shall be made successively whenever any event listed
            above shall occur.

                  (b) In case the Company shall issue or fix a record
            date for the issuance to all holders of Common Stock of
            rights, options, or warrants 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 or exchange price per share, if a
            security convertible into or exchangeable for Common
            Stock) less than the Exercise Price per share of Common
            Stock on such record date, then, in each case, the
            Exercise Price shall be adjusted by multiplying the
            Exercise Price in effect immediately prior to such record
            date by a fraction, the numerator of which shall be the
            number of shares of Common Stock outstanding on such
            record date plus the number of shares of Common Stock
            which the aggregate offering price of the total number of
            shares of Common Stock so to be offered (or the aggregate
            initial conversion or exchange price of the convertible or
            exchangeable securities so to be offered) would purchase
            at such current Exercise Price and the denominator of
            which shall be the number of shares of Common Stock
            outstanding on such record date plus the number of
            additional shares of Common Stock to be offered for
            subscription or purchase (or into which the convertible or
            exchangeable securities so to be offered are initially
            convertible or exchangeable). Such adjustment shall become
            effective at the close of business on such record date;
            provided, however, that, to the extent the shares of
            Common Stock (or securities convertible into or
            exchangeable for shares of Common Stock) are not
            delivered, the Exercise Price shall be readjusted after
            the expiration of such rights, options, or warrants (but
            only with respect to Warrants exercised after such
            expiration), to the Exercise Price which would then be in
            effect had the adjustments made upon the issuance of such
            rights, options, or warrants been made upon the basis of
            delivery of only the number of shares of Common Stock (or
            securities convertible into or exchangeable for shares of
            Common Stock) actually issued. In case any subscription
            price may be paid in a consideration part or all of which
            shall be in a form other than cash, the value of such
            consideration shall be as determined in good faith by the
            board of directors of the Company, whose determination
            shall be conclusive absent manifest error. Shares of
            Common Stock owned by or held for the account of the
            Company or any majority-owned subsidiary shall not be
            deemed outstanding for the purpose of any such
            computation.

                  (c) In case the Company shall distribute to all
            holders of Common Stock (including any such distribution made
            to the stockholders of the Company in connection with a
            consolidation or merger in which the Company is the continuing
            corporation) evidences of its indebtedness or assets (other
            than cash dividends or distributions and dividends payable in
            shares of Common Stock), or rights, options, or warrants to
            subscribe for or purchase Common Stock, or securities
            convertible into or exchangeable for shares of Common Stock
            (excluding those with respect to the issuance of which an
            adjustment of the Exercise Price is provided pursuant to
            Section 5(b) hereof), then, in each case, the Exercise Price
            shall be adjusted by multiplying the Exercise Price in effect
            immediately prior to the record date for the determination of
            stockholders entitled to receive such distribution by a
            fraction, the numerator of which shall be the Exercise Price
            per share of Common Stock on such record date, less the fair
            market value (as determined in good faith by the board of
            directors of the Company, whose determination shall be
            conclusive absent manifest error) of the portion of the
            evidences of indebtedness or assets so to be distributed, or of
            such rights, options, or warrants or convertible or
            exchangeable securities, applicable to one share, and the
            denominator of which shall be such current Exercise Price per
            share of Common Stock. Such adjustment shall be made whenever
            any such distribution is made, and shall become effective on
            the record date for the determination of shareholders entitled
            to receive such distribution.

                  (d) In case the Company shall issue shares of Common
            Stock or rights, options, or warrants to subscribe for or
            purchase Common Stock, or securities convertible into or
            exchangeable for Common Stock (excluding only shares, rights,
            options, warrants, or convertible or exchangeable securities
            issued or issuable (i) in any of the transactions with respect
            to which an adjustment of the Exercise Price is provided
            pursuant to Sections 5(a), 5(b) or 5(c) above, (ii) upon
            exercise, in whole or in part, of the Warrants or (iii) to
            management or employees of the Company of authorized shares of
            Common Stock), at a price per share (determined, in the case of
            such rights, options, warrants, or convertible or exchangeable
            securities, by dividing (x) the total amount received or
            receivable by the Company in consideration of the sale and
            issuance of such rights, options, warrants, or convertible or
            exchangeable securities, plus the minimum aggregate
            consideration payable to the Company upon exercise, conversion,
            or exchange thereof, by (y) the maximum number of shares
            covered by such rights, options, warrants, or convertible or
            exchangeable securities) lower than the Exercise Price per
            share of Common Stock in effect immediately prior to such
            issuance, then the Exercise Price shall be reduced on the date
            of such issuance to a price (calculated to the nearest cent)
            determined by multiplying the Exercise Price in effect
            immediately prior to such issuance by a fraction, (i) the
            numerator of which shall be an amount equal to the sum of (A)
            the number of shares of Common Stock outstanding immediately
            prior to such issuance plus (B) the quotient obtained by
            dividing the consider ation received by the Company upon such
            issuance by such current Exercise Price, and (ii) the
            denominator of which shall be the total number of shares of
            Common Stock outstanding immediately after such issuance. For
            the purposes of such adjustments, the maximum number of shares
            which the holders of any such rights, options, warrants, or
            convertible or exchangeable securities shall be entitled to
            initially subscribe for or purchase or convert or exchange such
            securities into shall be deemed to be issued and outstanding as
            of the date of such issuance, and the consideration received by
            the Company therefor shall be deemed to be the consideration
            received by the Company for such rights, options, warrants, or
            convertible or exchangeable securities, plus the minimum
            aggregate consideration or premiums stated in such rights,
            options, warrants, or convertible or exchangeable securities to
            be paid for the shares covered thereby. No further adjustment
            of the Exercise Price shall be made as a result of the actual
            issuance of shares of Common Stock on exercise of such rights,
            options, or warrants or on conversion or exchange of such
            convertible or exchangeable securities. On the expiration or
            the termination of such rights, options, or warrants, or the
            termination of such right to convert or exchange, the Exercise
            Price shall be readjusted (but only with respect to Warrants
            exercised after such expiration or termination) to such
            Exercise Price as would have obtained had the adjustments made
            upon the issuance of such rights, options, warrants, or
            convertible or exchangeable securities been made upon the basis
            of the delivery of only the number of shares of Common Stock
            actually delivered upon the exercise of such rights, options,
            or warrants or upon the conversion or exchange of any such
            securities; and on any change of the number of shares of Common
            Stock deliverable upon the exercise of any such rights,
            options, or warrants or conversion or exchange of such
            convertible or exchangeable securities or any change in the
            consideration to be received by the Company upon such exercise,
            conversion, or exchange, including, but not limited to, a
            change resulting from the antidilution provisions thereof, the
            Exercise Price, as then in effect, shall forthwith be
            readjusted (but only with respect to Warrants exercised after
            such change) to such Exercise Price as would have been obtained
            had an adjustment been made upon the issuance of such rights,
            options, or warrants not exercised prior to such change, or
            securities not converted or exchanged prior to such change, on
            the basis of such change. In case the Company shall issue
            shares of Common Stock or any such rights, options, warrants,
            or convertible or exchangeable securities for a consideration
            consisting, in whole or in part, of property other than cash or
            its equivalent, then the "price per share" and the
            "consideration received by the Company" for purposes of the
            first sentence of this Section 5(d) shall be as determined in
            good faith by the board of directors of the Company, whose
            determination shall be conclusive absent manifest error. Shares
            of Common Stock owned by or held for the account of the Company
            or any majority-owned subsidiary shall not be deemed
            outstanding for the purpose of any such computation.

                  (e) No adjustment in the Exercise Price shall be
            required if such adjustment is less than $0.10; provided,
            however, that any adjustments which by reason of this
            Section 5 are not required to be made shall be carried
            forward and taken into account in any subsequent
            adjustment. All calculations under this Section 5 shall be
            made to the nearest cent or to the nearest one-thousandth
            of a share, as the case may be.

                  (f) In any case in which this Section 5 shall
            require that an adjustment in the Exercise Price be made
            effective as of a record date for a specified event, the
            Company may elect to defer, until the occurrence of such
            event, issuing to the Holder, if the Holder exercised this
            Warrant after such record date, the shares of Common
            Stock, if any, issuable upon such exercise over and above
            the shares of Common Stock, if any, issuable upon such
            exercise on the basis of the Exercise Price in effect
            prior to such adjustment; provided, however, that the
            Company shall deliver to the Holder a due bill or other
            appropriate instrument evidencing the Holder's right to
            receive such additional shares upon the occurrence of the
            event requiring such adjustment.

                  (g) Upon each adjustment of the Exercise Price as a
            result of the calculations made in Sections 5(b), 5(c) or
            5(d) hereof, this Warrant shall thereafter evidence the
            right to purchase, at the adjusted Exercise Price, that
            number of shares (calculated to the nearest thousandth)
            obtained by dividing (A) the product obtained by
            multiplying the number of shares purchasable upon exercise
            of this Warrant prior to adjustment of the number of
            shares by the Exercise Price in effect prior to adjustment
            of the Exercise Price by (B) the Exercise Price in effect
            after such adjustment of the Exercise Price.

                  (h) Whenever there shall be an adjustment as
            provided in this Section 5, the Company shall promptly
            cause written notice thereof to be sent by registered
            mail, postage prepaid, to the Holder, at its address as it
            shall appear in the Warrant Register, which notice shall
            be accompanied by an officer's certificate setting forth
            the number of Warrant Shares purchasable upon the exercise
            of this Warrant and the Exercise Price after such
            adjustment and setting forth a brief statement of the
            facts requiring such adjustment and the computation
            thereof, which officer's certificate shall be conclusive
            evidence of the correctness of any such adjustment absent
            manifest error.

                  (i) The foregoing provisions of this Section 5
            notwithstanding, no adjustments shall be made under this
            Section 5 in respect of any shares of Common Stock issued
            or issuable pursuant to a stock option plan anticipated to
            be approved by Lanxide on or before March 31, 1998 (i)
            pursuant to which certain employees of Lanxide will be
            given five year options to acquire shares of Common Stock
            for an exercise price anticipated to be $1.00 per share
            and (ii) under which the aggregate number of shares to be
            reserved for issuance is not to exceed twenty-five percent
            (25%)of the issued and outstanding shares of Common Stock
            as of the date hereof on a fully diluted basis, including
            the Warrant Shares.

      6.          (a) In case of any consolidation with or merger of
            the Company with or into another corporation (other than a
            merger or consolidation in which the Company is the surviving
            or continuing corporation), or in case of any sale, lease, or
            conveyance to another corporation of the property and assets of
            any nature of the Company as an entirety or substantially as an
            entirety, such successor, leasing, or purchasing corporation,
            as the case may be, shall (i) execute with the Holder an
            agreement providing that the Holder shall have the right
            thereafter to receive upon exercise of this Warrant solely the
            kind and amount of shares of stock and other securities,
            property, cash, or any combination thereof receivable upon such
            consolidation, merger, sale, lease, or conveyance by a holder
            of the number of shares of Common Stock for which this Warrant
            might have been exercised immediately prior to such
            consolidation, merger, sale, lease, or conveyance and (ii) make
            effective provision in its certificate of incorporation or
            otherwise, if necessary, to effect such agreement. Such
            agreement shall provide for adjustments which shall be as
            nearly equivalent as practicable to the adjustments in Section
            5.

                  (b) In case of any reclassification or change of the
            shares of Common Stock issuable upon exercise of this
            Warrant (other than a change in par value or from no par
            value to a specified par value, or as a result of a
            subdivision or combination, but including any change in
            the shares into two or more classes or series of shares),
            or in case of any consolidation or merger of another
            corporation into the Company in which the Company is the
            surviving or 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 shares of
            Common Stock (other than a change in par value, or from no
            par value to a specified par value, or as a result of a
            subdivision or combination, but including any change in
            the shares into two or more classes or series of shares),
            the Holder shall have the right thereafter to receive upon
            exercise of this Warrant solely the kind and amount of
            shares of stock and other securities, property, cash, or
            any combination thereof receivable upon such
            reclassification, change, consolidation, or merger by a
            holder of the number of shares of Common Stock for which
            this Warrant might have been exercised immediately prior
            to such reclassification, change, consolidation, or
            merger. Thereafter, appropriate provision shall be made
            for adjustments which shall be as nearly equivalent as
            practicable to the adjustments in Section 5.

                  (c) The above provisions of this Section 6 shall
            similarly apply to successive reclassifications and
            changes of shares of Common Stock and to successive
            consolidations, mergers, sales,
            leases, or conveyances.

      7.          In case at any time the Company shall propose

                  (a) to pay any dividend or make any distribution on
            shares of Common Stock in shares of Common Stock or make
            any other distribution (other than regularly scheduled
            cash dividends which are not in a greater amount per share
            than the most recent such cash dividend) to all holders of
            Common Stock; or

                  (b) to issue any rights, warrants, or other
            securities to all holders of Common Stock entitling them
            to purchase any additional shares of Common Stock or any
            other rights, warrants, or other securities; or

                  (c) to effect any reclassification or change of
            outstanding shares of Common Stock, or any consolidation,
            merger, sale, lease, or conveyance of property, described
            in Section 6; or

                  (d) to effect any liquidation, dissolution, or
            winding-up of the Company; or

                  (e) to take any other action which would cause an
            adjustment to the Exercise Price;

then, and in any one or more of such cases, the Company shall give
written notice thereof, by registered mail, postage prepaid, to the
Holder at the Holder's address as it shall appear in the Warrant
Register, mailed at least 10 days prior to (i) the date as of which
the holders of record of shares of Common Stock to be entitled to
receive any such dividend, distribution, rights, warrants, or other
securities are to be determined, (ii) the date on which any such
reclassification, change of outstanding shares of Common Stock,
consolidation, merger, sale, lease, conveyance of property,
liquidation, dissolution, or winding-up is expected to become
effective, and the date as of which it is expected that holders of
record of shares of Common Stock shall be entitled to exchange their
shares for securities or other property, if any, deliverable upon such
reclassification, change of outstanding shares, consolidation, merger,
sale, lease, conveyance of property, liquidation, dissolution, or
winding-up, or (iii) the date of such action which would require an
adjustment to the Exercise Price.

      8.          The issuance of any shares or other securities
            upon the exercise of this Warrant, and the delivery of
            certificates or other instruments representing such shares or
            other securities, shall be made without charge to the Holder
            for any tax or other charge in respect of such issuance. The
            Company shall not, however, be required to pay any tax which
            may be payable in respect of any transfer involved in the issue
            and delivery of any certificate in a name other than that of
            the Holder and the Company shall not be required to issue or
            deliver any such certificate unless and until the person or
            persons requesting the issue thereof shall have paid to the
            Company the amount of such tax or shall have established to
            the satisfaction of the Company that such tax has been paid.

      9.          Certificates evidencing the Warrant Shares issued upon
            exercise of the Warrants shall bear the following legend:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
            SHARES MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
            EFFECTIVE REGISTRATION STATE MENT UNDER SUCH ACT, OR AN
            EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

      10.         Upon receipt of evidence satisfactory to the
            Company of the loss, theft, destruction, or mutilation of any
            Warrant (and upon surrender of any Warrant if mutilated) and a
            certificate executed by the Holder and provided by the Company
            pursuant to which the Holder agrees to indemnify the Company
            for any claims, losses or liability the Company may suffer on
            account of the issuance of a new certificate, and upon
            reimbursement of the Company's reasonable incidental expenses,
            the Company shall execute and deliver to the Holder thereof a
            new Warrant of like date, tenor and denomination.

      11.         The Holder of any Warrant shall not have, solely
            on account of such status, any rights of a stockholder of the
            Company, either at law or in equity, or to any notice of
            meetings of stockholders or of any other proceedings of the
            Company, except as provided in this Warrant.

      12.         Any notice or other communication required or
            permitted to be given hereunder shall be in writing and shall
            be mailed by certified mail, return receipt requested or sent
            by Federal Express, Express Mail, or similar overnight delivery
            or courier service or delivered (in person or by telecopy,
            telex, or similar telecommunications equipment) against receipt

                                EXHIBIT "B"


                      CERTIFICATE OF STOCK DESIGNATION

                                     OF

                            LANXIDE CORPORATION

                PERTAINING TO ITS PREFERRED STOCK, SERIES H


      It is hereby certified that:

      1.    The name of the corporation (hereinafter called the
"Corporation") is LANXIDE CORPORATION.

      2. The certificate of incorporation of the Corporation authorizes the
issuance of 15,000,000 shares of preferred stock of the Corporation having
a par value of $.01 per share (the "Preferred Stock"), and expressly vests
in the Board of Directors of the Corporation the authority provided therein
to fix by resolution or resolutions the designation, number, preferences
and relative, participating, optional and other special rights and the
qualifications, limitations, restrictions and other distinguishing
characteristics of each series of Preferred Stock to be issued.

      3. The Board of Directors of the Corporation, pursuant to the
authority expressly vested in it as aforesaid, has adopted the following
resolutions creating a Series H issue of the Preferred Stock of the
Corporation as follows:

            RESOLVED: That there shall be created a series of the Preferred
            Stock of the Corporation, to be designated as "Series H" of
            such Preferred Stock and to consist of 20,000 shares of such
            Preferred Stock (each a "Share" and collectively the "Shares"),
            which will have relative rights, preferences and limitations as
            follows:

                          Series H Preferred Stock

      Section 1. Dividends. The Series H Preferred Stock will not entitle
the holders thereof to receive any dividends in respect of such Series H
Preferred Stock; provided, however, that this Section 1 shall not prohibit
or impair payments to the holders of the Series H Preferred Stock upon
liquidation, dissolution or winding up of the Corporation in accordance
with Section 2 below.

      Section 2. Liquidation. Upon any liquidation, dissolution or winding
up of the Corporation, each holder of Series H Preferred Stock will be
entitled to be paid, out of the net assets of the Corporation available for
distribution to stockholders of the Corporation, and before any
distribution or payment is made upon any Junior Securities, an amount in
cash equal to the aggregate Liquidation Value of all Shares held by such
holder, and the holders of Series H Preferred Stock will not be entitled to
any further payment. If upon any such liquidation, dissolution or winding
up of the Corporation, the Corporation's assets to be distributed among the
holders of the Series H Preferred Stock and the holders of all outstanding
shares of any other series or class of preferred stock that are not Junior
Securities and which rank on a parity as to liquidation with the Series H
Preferred Stock are insufficient to permit payment to such holders of the
aggregate amounts which they are entitled to be paid, then the entire
assets to be distributed will be distributed ratably among such holders
based upon the aggregate Liquidation Value of the Series H Preferred Stock
and such other preferred stock held by each such holder. The Corporation
will mail written notice of such liquidation, dissolution or winding up,
not less than thirty (30) days prior to the payment date stated therein, to
each record holder of Series H Preferred Stock. Neither the consolidation
or merger of the Corporation into or with any other entity or entities, nor
the sale or transfer by the Corporation of all or any part of its assets,
nor the reduction of the capital stock of the Corporation, will be deemed
to be a liquidation, dissolution or winding up of the Corporation within
the meaning of this Section 2.

      Section 3. Priority of Series H Preferred Stock. The Series H
Preferred Stock shall rank junior to the Corporation's issued and
outstanding Series A Preferred Stock, and shall rank senior to the
Corporation's Series E Preferred Stock. So long as any of the Series H
Preferred Stock remains outstanding, neither the Corporation nor any
Subsidiary will:

            3.1 authorize or issue any class of preferred stock or other 
equity securities which shall rank senior to the Series H Preferred Stock;

            3.2 redeem, purchase or otherwise acquire directly or
indirectly any securities ranking on a parity with the Series H Preferred
Stock, unless the Corporation shall first offer to the holder(s) of the
Series H Preferred Stock, pursuant to written notice given not more than
sixty (60) and not less than (30) days' prior to the date fixed for such
redemption, purchase or acquisition, an opportunity to participate with the
holders of such other parity securities in such redemption, purchase or
acquisition on a ratable basis with such holders of such other parity
securities, based upon the aggregate Liquidation Value of the Series H
Preferred Stock and such other parity securities held by each such holder;
or

            3.3 redeem, purchase or otherwise acquire directly or
indirectly any Junior Securities (other than shares of Series E Preferred
Stock pursuant to the terms of its certificate of designations), or
directly or indirectly pay or declare any dividend or make any distribution
upon any Junior Securities, other than dividends payable solely in Junior
Securities.

      Section 4. Redemptions.

            4.1 Mandatory Redemption. The Series H Preferred Stock shall
not be subject to mandatory redemption by the holder; provided, however,
that to the extent that (i) any holder of Series H Preferred Stock is also
the registered owner of a Warrant of the Corporation, (ii) such holder has
determined to exercise such Warrant for shares of Common Stock of the
Corporation and (iii) such holder has elected to pay all or any portion of
the exercise price for such shares of Common Stock by the tender of one or
more shares of Series H Preferred Stock in accordance with the terms of
such Warrant, then the Corporation shall redeem and cancel such number of
Shares of Series H Preferred Stock as so tendered.

            4.2 Optional Redemption. The Series H Preferred Stock may not
be redeemed at the option of the Corporation prior to December 31, 1998. At
any time, or from time to time, from and after December 31, 1998, the
Series H Preferred Stock may be redeemed at the Liquidation Value per
Share, at the sole option of the Corporation. Any optional redemption by
the Corporation hereunder will be made upon not less than thirty (30) days'
prior written notice and not more than sixty (60) days' prior written
notice to the holders of the outstanding Series H Preferred Stock. The
holders of the Series H Preferred Stock shall have the right, exercisable
in their sole discretion at any time prior to the date fixed for
redemption, to utilize all or any portion of such Series H Preferred Stock
to exercise the Warrant and pay the exercise price therefore in such shares
of Series H Preferred Stock in accordance with Section 4.1 above and the
terms of such Warrant. Subject to the foregoing, on the date fixed for
redemption, the Corporation shall pay to the holders thereof the applicable
redemption price for all other shares of Series H Preferred Stock called
for redemption (such payment to be made, at the Corporation's option, by
wire transfer of immediately available funds or by certified or bank
cashier's check). Each date fixed for any such optional redemption is
herein referred to as an "Optional Redemption Date."

            4.3 Redemption Procedure. For each Share of Series H Preferred
Stock which is to be redeemed, the Corporation will be obligated on the
subject Optional Redemption Date to pay to the holder thereof (upon
surrender by such holder at the Corporation's principal office of the
certificate representing such Share) an amount in immediately available
funds equal to applicable redemption price therefor at the Liquidation
Value per Share.

            4.4 Reissuance of Certificates. In case fewer than the total
number of Shares represented by any stock certificate are redeemed or
converted, a new certificate representing the number of unredeemed and
unconverted Shares will be issued to the holder thereof without cost to
such holder within five (5) business days after surrender of the
certificate representing the redeemed Shares.

            4.5 Redeemed or Otherwise Acquired Shares. Any Shares which are
redeemed or otherwise acquired by the Corporation will be canceled and, so
long as any Series H Preferred Stock remains outstanding, such Shares may
thereafter be reissued as such Series H Preferred Stock or as a part of a
new series of Preferred Stock of the Corporation to be created by
resolution or resolutions of the Board of Directors of the Corporation.

      Section 5. Conversion. Except as otherwise provided in any Warrant to
acquire Shares of Common Stock pursuant to Section 4.1 above, the Series H
Preferred Stock shall not be convertible into Common Stock or any other
securities of the Corporation.

      Section 6. Voting Rights and Consent.

            6.1 General. Except for any matters for which separate class
voting is provided in Section 6.2 below, the Shares of Series H Preferred
Stock shall not be entitled to vote on any matter requiring the affirmative
vote or ratification by stockholders of the Corporation.

            6.2 Separate Class Voting. The holders of the outstanding
Shares shall be entitled, voting as a separate class, to vote with respect
only to any change in the preferences, rights or limitations of the Series
H Preferred Stock (with the affirmative vote of the holders of a majority
of the Shares then outstanding being required for the adoption or approval
of any such matter).

      Section 7. Costs. The Corporation shall pay all documentary, stamp,
transfer or other transactional taxes attributable to the issuance or
delivery of shares of Common Stock upon exercise of the Warrant and
exchange of any shares of the Series H Preferred Stock; provided, however,
that the Corporation shall not be required to pay any federal or state
income taxes or other taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificate for such shares in
a name other than that of the holder of the shares of the Series H
Preferred Stock in respect of which such shares are being issued.

      Section 8. Consolidation, Merger, Sale, Lease or Conveyance. In case
of any consolidation with or merger of the Corporation with or into another
corporation or other Person who is not an Affiliate of the Corporation, or
in case of any sale, lease or conveyance to another corporation or other
Person who is not an Affiliate of the Corporation of the assets of the
Corporation as an entirety or substantially as an entirety (a "Sale of
Control"), each outstanding Share of the Series H Preferred Stock shall, on
or within five (5) business days after the date of such Sale of Control, be
redeemed by the successor-in-interest to the Corporation for cash at the

principal office a register for the registration of Series H Preferred
Stock. Upon the surrender of any certificate representing Series H
Preferred Stock at such place, the Corporation will, at the written request
of the record holder of such certificate, execute and deliver (at the
Corporation's expense) a new certificate or certificates in exchange
therefor representing in the aggregate the number of Shares represented by
the surrendered certificate. Each such new certificate will be registered

      NEWARK, DELAWARE. . .March 6, 1998   Lanxide Corporation (OTC Bulletin
 Board:  LNXI), today announced that it has issued a royalty-bearing license
 to Commodore Environmental Services, Inc. (OTC Bulletin Board:  COES) to
 use CERASET  on a worldwide basis, excluding Japan.  The license gives
 Commodore certain business and technology rights that do not conflict with
 the rights of Lanxide's other 13 licensees or future licensees in the
 fields for metal matrix composites and ceramic matrix composites. 
  
      Payment for the license included cash, and in addition, cancellation
 of loans from Commodore to a Lanxide subsidiary in the amount of $4.5
 million plus accrued interest.  This license transaction was accompanied by
 a restructuring of various agreements between Lanxide and Commodore. 
  
      Lanxide appointed Michael J. Hollins to its Board of Directors and to
 serve as Vice President, Operations for the Company.  In addition, the
 Company recommenced operations with a smaller employee base. 
  
      Last month Lanxide had laid off all its employees and sought to
 restructure its operations.  In that connection it sold two of its
 subsidiaries to DHB Capital Group Inc.  While the Company has commenced
 operations with reduced debt and some additional working capital, it is
 still working on additional restructuring measures necessary to improve the
 Company's working capital position. 
  
      Any questions can be directed to the spokesman for the Company:
