                                  COVENANTS

      Section 4.1 Covenants of Seller.  Seller covenants to Buyer as follows:
                  -------------------

      (a) Corporate Action. As soon as practicable, but in any event prior to
                      ----------------
Closing, Seller shall approve the acquisition of the Stock by Buyer under
Section 203 of the Delaware General Corporation Law.  Seller agrees that it
will not adopt any amendments to its Corporate Documents or take or recommend
to its stockholders any action which would (i) impose limitations on the legal
rights of Buyer including, without limitation, any action which would impose
restrictions: (A) based upon the size of security holding, the business in
which Buyer is engaged or other considerations applicable to Buyer and not to
stockholders generally; (B) with reference to the Common Stock generally, by
means of the issuance (other than pursuant to Options outstanding as of the
date of this Agreement) or proposal to issue any other class of securities
having voting power disproportionately greater than the equity investment in
the Seller represented by the Common Stock; (ii) deny any benefit to Buyer as
a holder of Common Stock that is made available to other holders of Common
Stock generally; or (iii) alter voting or other rights of the holders of
Common Stock so that such rights (or the vote required with respect to any
matter) are determined in reference to the amount of Common Stock held by Buyer.

      (b)   Marketing Position.  Within six (6) months after Closing, Seller
            ------------------
shall create a Vice President of Marketing position for the purpose of
commercialization of the Seller's technology.

      (c) Restrictions. For so long as Buyer and its Affiliates Beneficially
          ------------
Own an aggregate of more than Five Percent (5%) of Seller Stock:

            (i) without Buyer's prior written consent, Seller shall not,
      directly or indirectly issue more than Nine and Nine Tenths Percent
      (9.9%) of the Seller Stock (or Options or Warrants or other securities
      convertible into Seller Stock) to any other Person in one or a series
      of related transactions;

            (ii) if  Seller determines to pursue a merger, consolidation or
      sale of all or substantially all of its assets (a "Business Combination")
      (other than pursuant to an unsolicited proposal in which case Section
      4.1 (c) (iii) below will govern), it will not initiate such a Business
      Combination, until Forty-Five Business (45) Days after it has given
      prior written notice of its intent to pursue such transaction (a
      "Business Combination Notice") to Buyer. During such Forty-Five Business
      Day period Seller shall negotiate in good faith such a Business
      Combination with the Buyer.  If Buyer and Seller are unable to enter
      into a definitive agreement with respect to a Business Combination
      within that period, then, subject to Section 4.1 (c) (iii) below,
      Seller shall be free to initiate such discussions with other parties; and



                                      15




<PAGE>




            (iii) Seller will not enter into a binding agreement with any Person
      relating to a Business Combination, whether pursuant to an unsolicited
      proposal from any other Person or initiated by the Seller, unless it has
      provided Buyer with a Business Combination Notice at least Ten (10)
      Business Days prior to entering in to such an agreement. Such business
      Combination Notice shall set forth in reasonable detail the terms and
      conditions of the proposed Business Combination, including the fair market
      value of the consideration to be received by Seller or its stockholders.
      The Business Combination Notice will include a copy of any written offer,
      term sheet or similar document received by Seller in connection with the
      proposed transaction. If Buyer, within Ten (10) Business Days after the
      delivery of the Business Combination Notice by Seller, notifies Seller of
      its intention to enter into a Business Combination with Seller on the
      terms and conditions set forth in the Business Combination Notice, then
      Seller and Buyer will act promptly and in good faith to negotiate a
      definitive agreement reflecting such terms and conditions. If the parties,
      so acting, are unable to negotiate and execute such definitive agreement
      within a period of Ten (10) Business Days after the date Buyer's notice is
      given to Seller, then Seller, by delivery of written notice to Buyer, may
      discontinue such negotiations. Seller may, within 120 days after the
      delivery of notice discontinuing such negotiations, enter into a
      definitive agreement providing for a Business Combination upon terms and
      conditions not materially less favorable, in the aggregate, to Seller and
      its stockholders than the terms and conditions set forth in the Business
      Combination Notice.

Stock, if the Seller shall issue any Seller Stock, Buyer shall have the right to
purchase an amount of Seller Stock so that, after the issuance of all such
Seller Stock, Buyer would, in the aggregate, hold the same proportionate
interest in such Seller Stock as is held by it prior to the issuance of any such
additional Seller Stock. If such Seller Stock is Common Stock, the purchase
price thereof shall be calculated as provided in Section 2.3 hereof utilizing
the five days preceding the first announcement of the relevant transaction. If
such Seller Stock is not Common Stock, the purchase price shall be the issue
price of such security. In connection with any issuance by Seller subject to the
provisions of this Section 4.1(d), Seller shall promptly deliver a notice (a
"Preemptive Rights Notice") of such issuance to the Buyer, provided that if such
issuance is pursuant to the exercise of Options or Warrants or other convertible
Seller Stock and represents less than 20,000 shares, Seller may aggregate such
requests and deliver a Preemptive Rights Notice to Buyer relative thereto at the
end of the fiscal quarter in which the issuance is made. Buyer's right to
purchase securities under this Section 4.1(d) with respect to any issuance of
securities shall terminate fifteen (15) Business Days after the delivery of the
Preemptive Rights Notice.

      combination or other similar transaction involving Seller or any of its
      Affiliates (it is agreed that this restriction relates to proposals for
      all or substantially all of Sellers business and in no way limits the
      ability of the Buyer to propose joint ventures or other arrangements to
      develop and commercialize Sellers technologies similar to those
      contemplated in Section 4.3(e)); (B) make or in any way participate in any
      "solicitation" of "proxies" (as such terms are used in the proxy rules of

      respect to the voting of any voting securities of Seller or any of its
      Affiliates; (C) form, join or in any way participate in a "group" (within
      the meaning of Section 13(d)(3) of the Securities Act) with respect to any
      voting securities of Seller or any of its Affiliates; (D) disclose any
      intention, plan or arrangement inconsistent with the foregoing; or (E)
      advise, assist or encourage any other Persons (including specifically
      Seller's shareholders) in connection with any of the foregoing. Buyer

      of its Affiliate to take any action which might require Seller or any of
      its Affiliates to make a public announcement regarding the possibility of
      a merger, consolidation, business combination or other similar
      transaction.

      Section 4.3 Covenants of Seller and Buyer.  Seller and Buyer covenant to
                  -----------------------------
each other as follows:

      (a) Compliance with Conditions Precedent. Seller and Buyer shall each use
          ------------------------------------
its best efforts to cause the conditions precedent set forth in Part Six, as
applicable to such Party, to be fulfilled and satisfied as soon as practicable.

      (b) Brokers. Each Party shall have sole responsibility for the fees and
          -------
expenses of any financial or other advisor retained by it with respect to the
transactions contemplated hereby and neither Party shall have responsibility for
the fees and expenses of any advisors retained by the other.

      (c) Press Release. The Parties agree to consult with each other before
          -------------
issuing any press release or making any public statement with respect to this
Agreement and the transactions contemplated hereby. Neither Party shall make any
press release or other announcement respecting this Agreement without the
consent of the other unless a Party refuses to consent and the Party desiring to
make the release or other announcement is advised by its counsel that the
release or other announcement is required to comply with any statute, law or
regulation.

      (d)   Board of Directors.  With respect to the Board of Directors of the
            ------------------
Seller:

            (i) Buyer shall be entitled to designate nominees for director of
      Seller's Board of Directors. For so long as Buyer and its Affiliates
      Beneficially Own an aggregate of more than Five Percent (5%) of Sellers
      Stock, Buyer shall be entitled to designate one nominee; to the extent
      Buyer and its Affiliates Beneficially Own an aggregate of more than Ten
      Percent (10%) of Seller Stock, then Buyer may designate two nominees or
      one-fifth of the number of directors then serving, whichever is greater.
      Seller agrees to appoint two nominees designated by Buyer to the Board of
      Directors of Seller as soon as practical after Closing and in any event at
      the next regular meeting of the Board of Directors. Subsequently, Seller
      agrees to use its best efforts to take all actions necessary to have
      Buyer's nominees elected to the Board of Director and Committees,
      including without limitation, the nominee in the Seller's proxy statement,
      recommending a vote for such nominee and casting proxies given to Seller
      in the favor of such nominee. The directors nominated pursuant to this
      Section 4.3(d) shall be entitled to receive the same compensation and
      benefits that are provided to the other non-executive members of the Board
      of Directors.

            (ii) For so long as Buyer and its Affiliates Beneficially Own an
      aggregate of more than Five Percent (5%) of Seller's Stock, Buyer shall
      also be entitled to have one of its designee's serve on appropriate
      committees of the Board of Directors, including the Audit Committee and
      any committee established for the purpose of succession planning.

                                      18





<PAGE>



            (i) Seller and Buyer intend, as soon as practicable after Closing,
      to enter into joint ventures to promote the development and
      commercialization of Ovonic Solid Hydrogen Storage Systems and Ovonic
      Regenerative Fuel Cell technology. In concept Seller would provide each
      venture with a license of Seller's Intellectual Property relating to the
      respective field and Buyer would provide funding to some agreed level. The
      agreements for each joint venture will provide for a set term during which
      definable progress must be identified or the joint ventures will
      terminate, in which event the right to control the Intellectual Property
      will revert to Seller. The Parties also acknowledge that it may be
      appropriate to include third parties in either or both of these joint
      ventures and the Parties will work together to identify potential
      co-venturers. Both Buyer and Seller shall have the right to nominate their
      employees for secondment to these joint ventures, subject to the
      concurrence of the other Party.

            (ii) The joint venture agreements referred to in Section 4.3 (e) (i)
      will provide that Seller shall give Buyer the first opportunity to
      participate in new or existing initiatives before commencing discussions
      with third parties relating to development and commercialization
      initiatives in the fields of hydrogen storage systems and Ovonic
      Regenerative Fuel Cell technology. If one of the ventures described in
      Section 4.3(e) (i) has been terminated because of the failure of Buyer to
      diligently pursue the development of the technology, then Seller shall not
      be obligated to provide Buyer the first opportunity to participate in
      subsequent initiatives utilizing that technology.

      (f)   Transfer Rights/Right of First Refusal.  Buyer and Seller agree:
            --------------------------------------

            (i) Buyer shall not sell, hypothecate, or otherwise transfer the
      Stock prior to the first anniversary of the Closing Date. On any sale of
      the Stock by Buyer to a single purchaser or a "group" (within the meaning
      of Section 13(d)(3) of the Securities Act) which represents more than Five
      Percent (5%) in the Seller Stock then outstanding, Buyer agrees to make
      the sale of the Stock by it subject to the agreement of the purchaser to
      be bound by the restrictions set forth in Section 4.2 (a) and (b).

            (ii) If there is a Change of Control or if, after the first
      anniversary of the Closing Date, Buyer desires to sell any the Stock, then
      Seller shall have a right to purchase the Stock. If Buyer intends to sell
      the Stock then it shall deliver a written notice to the Seller setting
      forth the proposed sale price and other proposed terms of sale, including
      the identity of any proposed transferee. If Seller intends to purchase the
      Stock, Seller shall notify Buyer in writing within Forty Five (45)
      Business Days of receipt of the Buyer's notice of intent to sell or a
      notice of Change of Control. In the case of a Change of Control, the price
      will be calculated on the same basis as the Purchase Price. In the case of
      an intent to sell, the acceptance will be on the specified terms and
      conditions specified in the notice. In either case, if Buyer does not
      receive Seller's acceptance within Forty Five (45) Business Days of
      Buyer's notice, Seller will have waived its right to purchase pursuant to
      this Section 4.3(f)(ii).




                                      19


<PAGE>




            (iii) Notwithstanding Section 4.3(f)(ii), prior to the completion of
      a sale of the Stock to a Person, Buyer shall grant Seller a right of first
      refusal with respect to the specific terms offered by a Person. Buyer
      shall notify Seller in writing of the terms and conditions upon which the
      Person is willing to purchase the Stock. Seller shall have the right to
      purchase the Stock on the terms and conditions set forth in such notice.
      If Buyer does not receive Seller's acceptance within ten (10) Business
      Days of Buyer's notice Seller shall have waived its right to purchase and
      Buyer may sell the Stock on terms and conditions no less favorable to the
      proposed purchaser than specified in its notice.

      (c)   Certain Filings and Consents.  With respect to certain filings and
            ----------------------------
consents, the Parties agree that:

            (i) Buyer and Seller shall promptly make all required submissions
      under the Hart Scott Rodino Antitrust Improvements Act of 1976 as amended
      ("HSR Act");

            (ii) Buyer and Seller shall cooperate with one another in (x)
      determining whether any filings are required to be made or consents,
      approvals, permits or authorizations are required to be obtained under
      any Laws of the United States or any other country in which Seller has
      business activities, and (y) making any such filings, furnishing
      information required in connection therewith and seeking timely to
      obtain any such consents, permits, authorizations, approvals or waivers;
      and (iii) Buyer shall promptly endeavor to obtain, and Seller shall
      reasonably cooperate in connection with such endeavors, each consent set
      forth on Schedules 3.1(e), 3.2(e) and 4.3(g), and (iv) Seller shall
      promptly endeavor to obtain, and Buyer shall reasonably cooperate in
      connection with such endeavors, each consent set forth on Schedules
      3.1(e), 3.2(e) and 4.3(g).

                              PART FIVE

Securities Act, of all or at least 250,000 shares of the Stock.

      Section 5.2 Expenses. The expenses of the holders of the Stock (other than
                  --------
underwriting discounts and commission applicable to the Stock of the Buyer to be
sold) shall be paid by the Seller in connection with the Registration.

      Section 5.3 Other Seller Stock. The Seller shall not include in the Stock
                  ------------------
Registration any securities which are not Stock, without the prior written
consent of the Buyer. If the Stock Registration is an underwritten offering and
the managing underwriters advise Seller that in their opinion the number of
shares of the Stock and, if permitted hereunder, other Seller Stock requested to
be included in such offering, exceeds the number of shares of the Stock and
other Stock which can be sold in an orderly manner in such offering within a
price range acceptable to



                                      20




<PAGE>



the Buyer, the Seller shall include in such registration prior to the inclusion
of any Seller Stock, which is not Stock, the Stock requested to be included,
which in the opinion of such underwriters can be sold in an orderly manner
within the price range of such offering.

      Section 5.4 Postponement. The Seller may postpone for up to One Hundred
                  ------------
Eighty (180 days) the filing or the effectiveness of a registration statement
for the Stock Registration if the Seller determines in good faith that such
Stock Registration would reasonably be expected to have an adverse effect on any
proposal or plan by the Seller to engage in any acquisition of assets (other
than in the ordinary course of business), merger, consolidation or tender offer
or to enter into any material license agreement, joint venture arrangement or
similar transaction; provided that in such event, the holders of the Stock shall
be entitled to withdraw such request and if such request is withdrawn, such
Stock Registration shall not count as the permitted Stock Registration hereunder
and the Seller shall pay all expenses in connection with such registration.

      Section 5.5 Piggyback Registration. Whenever the Seller proposes to
                  ----------------------
register any of its securities under the Securities Act (other than pursuant to
a Stock Registration and other than registrations on Form S-4, Form S-8 or any
similar or successor registration forms) and the registration form to be used
may be used for the registration of the Seller Stock (a "Piggyback
Registration"), the Seller shall give prompt written notice to the Buyer of its
intention to effect such a registration and shall include in such registration
all Seller Stock with respect to which the Seller has received written requests
for inclusion therein within 15 days after the giving of the Seller's notice.
The expenses of the holders of the Seller Stock (other than underwriting
discounts and commissions applicable to the Stock of Buyer) shall be paid by the
Seller in connection with all Piggyback Registrations.

      Section 5.6 Primary Piggyback Registration. If a Piggyback Registration is
                  ------------------------------
an underwritten primary registration on behalf of the Seller, and the managing
underwriters advise the Seller in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Seller, the Seller shall include in such registration (i)
first, the securities the Seller proposes to sell, (ii) second, the Stock and
any other securities requested to be included in such registration by holders
entitled to registration rights in connection therewith, pro rata among such
holders based on the number of shares requested to be included in such

registration.

      Section 5.7 Secondary Piggyback Registration If a Piggyback Registration
                  --------------------------------
is an underwritten secondary registration on behalf of holders of the Seller's
securities, and the managing underwriters advise the Sellers in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders initially requesting
such registration, the Seller will include in such registration (i) first, the
securities requested to be included therein by the holders requesting such
registration, (ii) second, the Stock and any other securities requested to be
included in such registration by holders entitled to registration rights in



                                      21




<PAGE>



connection therewith, pro rata among such holders based on the number of shares
requested to be included in such registration, and (iii) third, other securities
requested to be included in such registration.

      Section 5.8 Efforts. Whenever the holders of Stock have requested that any
                  -------
Stock be registered pursuant to this Agreement, the Seller shall use its
reasonable best efforts to effect the registration and the sale of such Stock in
accordance with the intended method of disposition.

      Section 5.9 Seller Indemnity. The Seller shall indemnify, to the extent
                  ----------------
permitted by Law, Buyer and the permitted assigns of the Stock , its officers
and directors and each Person who controls such holder (within the meaning of
the Securities Act) against all Losses 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 the
Seller by such holder expressly for use therein or by such holder's failure to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Seller has furnished such holder with a sufficient
number of copies of the same. In connection with an underwritten offering, the
Seller shall indemnify such underwriters, their officers and directors and each
Person who controls such underwriters (within the meaning of the Securities Act)
to the same extent as provided above with respect to the indemnification of the
holders of the Stock.

      Section 5.10 Information and Buyer Indemnity. In connection with any
                   -------------------------------
registration statement in which a holder is participating, Buyer shall furnish
and shall cause each such holder to furnish to the Seller in writing such
information and affidavits as the Seller reasonably requests for use in
connection with any such registration statement or prospectus and, to the extent
permitted by Law. Buyer shall indemnify the Seller, its directors and officers
and each Person who controls the Seller (within the meaning of the Securities
Act) against any Losses, 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 any information or
affidavit so furnished in writing by Buyer or the other holders, if any;
provided that the obligation to indemnify shall be limited to the net amount of
proceeds received by such holder from the sale of Stock pursuant to such
registration statement.

      Section 5.11(a) Third Party. In the event that any claim for which a Party
                      -----------
providing indemnification hereunder (the "Indemnitor") would be liable to a
Party entitled to indemnification hereunder (the "Indemnitee") is asserted
against or sought to be collected from Indemnitee by a third party, Indemnitee
shall promptly notify Indemnitor of such claim, specifying the nature of such
claim and the amount or the estimated amount thereof to the extent then feasible
(which estimate shall not be conclusive of the final amount of such claim) (the
"Claim Notice"). Indemnitor shall have fifteen (15) days from its receipt of the
Claim Notice



                                      22




<PAGE>



(the "Notice Period") to notify Indemnitee (i) whether or not it disputes its
liability to Indemnitee hereunder with respect to such claim, and (ii) if it
does not dispute such liability, whether or not it desires, at its sole cost and
expense, to defend Indemnitee against such claim; provided, however, that
Indemnitee is hereby authorized prior to and during the Notice Period to file
any motion, answer or other pleading which it shall deem necessary or
appropriate to protect its interests. In the event that Indemnitor notifies
Indemnitee within the Notice Period that it does not dispute such liability and
desires to defend against such claim or demand, then, except as hereinafter
provided, Indemnitor shall have the right to defend by appropriate proceedings,
which proceedings shall be promptly settled or prosecuted to a final conclusion
in such a manner as to avoid any risk of Indemnitee becoming subject to
liability. If Indemnitee desires to participate in, but not control, any defense
or settlement, it may do so at its own cost and expense. If Indemnitor disputes
its liability with respect to such claim, or elects not to defend against such
claim, whether by not giving timely notice as provided above or otherwise,
Indemnitee shall have the right but not the obligation to defend against such
claim, and the amount of any such claim, or if the same be contested by
Indemnitor or by Indemnitee, then that portion thereof as to which such defense
is unsuccessful, shall be conclusively deemed to be a liability of Indemnitor
hereunder (subject, if it has timely disputed liability, to a determination as
provided in Sections 5.11 and 7.12 that the disputed liability is covered by
these indemnification provisions).

      (b) Party's Claim. In the event that Indemnitee shall have a claim against
          -------------
Indemnitor hereunder which does not involve a claim or demand being asserted
against or sought to be collected from it by a third party, Indemnitee shall
promptly send a Claim Notice with respect to such claim to Indemnitor. If
Indemnitor does not notify Indemnitee within the Notice Period that it disputes
such claim, the amount of such claim shall be conclusively deemed a liability of
Indemnitor hereunder.

      (c) Disputed Claim. If Indemnitor shall notify Indemnitee during the
          --------------
Notice Period that it disputes any claim (the "Disputed Claim"), then the
Disputed Claim shall be submitted to arbitration pursuant to the provisions of
Section 7.12 of this Agreement.

          -----------------------
Buyer dated the Closing Date certifying to the incumbency of the officers of
Buyer signing for it and as to the authenticity of their signatures.

      (e) Opinion of Counsel. Buyer shall have delivered to Seller the opinion
          ------------------
of Leocadie A. Robertson , or such other counsel designated by Buyer, dated the
Closing Date, to the effect that:

            (1) Buyer has been duly organized and is validly existing and in
      good standing under the laws of Delaware.

            (2) Buyer has the corporate power and authority to enter into and
      perform this Agreement and to consummate the transactions contemplated
      hereby. The execution, delivery and performance of this Agreement and the
      consummation of the transactions contemplated hereby by Buyer have been
      duly authorized by all requisite corporate action and this Agreement has
      been duly executed and delivered by Buyer.

            (3) This Agreement is the legal, valid and binding obligation of
      Buyer and is enforceable against Buyer in accordance with its terms,
      except as may be limited by bankruptcy, insolvency, reorganization or
      other similar laws affecting the enforcement of creditors' rights in
      general. The enforceability of Buyer's obligations under this Agreement is
      subject to general principles of equity (regardless of whether enforcement
      is considered in a proceeding in equity or at law).

            (4) The execution and delivery by Buyer of this Agreement and the
      performance by Buyer of its terms does not (a) conflict with or result in
      a violation of the Corporate Documents of Buyer or any statute, law, writ,
      regulation, rule, order, judgment or decree of any court or Governmental
      Entity, known to me as counsel, to which Buyer or any of its assets may be
      subject, or (b) violate, conflict with, constitute a Default under, permit
      the termination of, or require the consent or approval of any Person
      (other than consents or approvals already obtained) under, any Contract
      known to me to which Buyer is a Party, or by which Buyer (or its assets or
      properties) is bound.

      In rendering the foregoing opinion, counsel may rely upon certificates of
officers of Buyer as to factual matters.

      (f) Consents; No Obstructive Proceedings. All government consents,
          ------------------------------------
registrations, declarations or filings with, or expiration of waiting periods
imposed by or agreed with any

governmental entity necessary for the purchase and sale of the Stock, including
