termination, the parties acknowledge the following:

                                       1

   4

                  (2)      Revenge is simultaneously issuing to BYC 1,206 shares
                           of its Series B Cumulative Convertible Preferred
                           Stock pursuant to a separate stock purchase
                           agreement.

                  (3)      Revenge is simultaneously issuing to BYC a warrant
                           (the "Warrant") to purchase up to 1,500,000 shares
                           (subject to adjustment) of Revenge's Common Stock,
                           par value $0.001 per share (the "Common Stock"), at
                           an exercise price of $0.37 per share (subject to
                           adjustment).

2. WARRANT. This section describes certain provisions specific to the Warrant
and the shares of Common Stock that BYC may from time to time acquire upon
exercise of the Warrant (the "Warrant Shares"):

         (a) DEMAND REGISTRATION. Upon BYC's written request in accordance with
Section 2(c) any time on or after the first anniversary of the first exercise of
the Warrant Shares but before the fourth anniversary of such exercise, Revenge
will use reasonable efforts to register under the Securities Act any Warrant
Shares, as soon as reasonably practicable following such request so as to permit
the sale of such shares. Revenge will be entitled to postpone for a reasonable
period of time, the filing of any registration statement otherwise required to
be prepared and filed by it with respect to such registration if, at the time it
receives such request, Revenge (i) in its reasonable judgment and based on the
advice of counsel, determines that such registration and sale would materially
interfere with any financing, acquisition, corporate reorganization or other
material transaction and promptly gives BYC written notice of such
determination, or (ii) has filed or is about to file a registration statement
relating to Revenge's securities and the managing underwriters of such offering
have advised in writing that the filing of a registration statement would
materially and adversely affect Revenge's offering. If Revenge so postpones a
registration statement filing, then BYC may withdraw the request for
registration by giving Revenge written notice within 30 calendar days after
receipt of the notice of postponement. Revenge will have no further obligation
to register any Warrant Shares under this Section 2(a) after it has filed two
separate registration statements that have become effective pursuant to requests
by BYC under this Section 2(a).

         (b) PIGGYBACK REGISTRATION. At any time after an initial public
offering of shares, if Revenge proposes to register under the Securities Act any
of its Common Stock or other securities convertible into Common Stock relating
to an underwritten public sale of such securities, it will at each such time
give written notice to BYC of its intention to do so, together with reasonable
details regarding such proposed registration and sale. Upon BYC's written
request in accordance with Section 2(c) made within 15 days after the receipt of
any such notice, Revenge will use reasonable efforts to include in such
registration the number of Warrant Shares requested by BYC. Notwithstanding the
foregoing, Revenge will not be required to provide BYC notice of, and BYC will
not have any right to have Warrant Shares included in, (i) a registration of
securities solely in connection with any plan for the acquisition of securities
by employees of Revenge or any dividend reinvestment plan, (ii) a registration
on Form S-4 or similar form or (iii) a registration of securities solely in
connection with the acquisition of a business. Revenge's obligations under this
Section 2(b) are subject to the following conditions:



                                       2

   5

         (1)      If at any time after giving written notice of its intention to
                  register any securities under this Section 2(b) and prior to
                  the effective date of the registration statement filed in
                  connection with such registration, Revenge determines for any
                  reason not to register such securities, Revenge will give BYC
                  written notice of such determination and, thereupon, will be
                  relieved from its obligation to proceed with such
                  registration.

         (2)      If the managing underwriter advises Revenge in writing that,
                  in its opinion, the amount of securities to be offered should
                  be limited in order to assure a successful offering, the
                  amount of Warrant Shares to be included in such registration
                  will be limited and will be allocated among the persons
                  selling such securities in the following order of priority:
                  (i) first to be registered will be the securities Revenge
                  proposes to sell, and (ii) next to be registered will be the
                  Warrant Shares and any other Common Stock subject to similar
                  piggyback registration rights granted by Revenge, in
                  proportion, as nearly as practicable, to the number of Common
                  Stock desired and eligible to be sold by each holder of such
                  Common Stock.

         (c) FORM OF BYC REQUEST. Each BYC request for registration under
Section 2(a) or (b) will (i) specify the number of Warrant Shares intended to be
offered and sold, and (ii) describe the intended method of disposition of such
Warrant Shares.

         (d) REGISTRATION EXPENSES. Revenge will pay all registration expenses
in connection with any registration of Warrant Shares under Section 2(a) or (b).
The registration expenses referred to in the preceding sentence include, without
limitation, the fees and expenses of Revenge's counsel and accountants, the
costs and expenses incident to the preparation, printing and filing by Revenge
of the registration statement (including the financial statements included in,
and all amendments and exhibits to, the registration statement), the preliminary
prospectus and the final prospectus and any amendment or supplement to any of
the foregoing, the filing fees of the Securities and Exchange Commission (the
"SEC"), the National Association of Securities Dealers, Inc., and of any state
securities or blue sky authorities, the fees and expenses of counsel in
connection with the qualification of the securities under state securities or
blue sky laws, the costs of printing and copying the various underwriting and
blue sky documents, any fees relating to the listing of the securities on the
National Association of Securities Dealers, Inc. Automated Quotation System or
in any other market in which Revenge's securities are traded, the cost of
printing certificates representing the securities being offered, any fees of the
transfer agent, the cost of preparing and publishing advertisements, including
"tombstone" advertisements, relating to the offering, and the cost of preparing
bound volumes relating to the offering; provided, however, that BYC and Revenge
shall share equally all costs of printing and delivering preliminary and final
prospectuses in connection with any registration of Warrant Shares under Section
2(a). BYC will be solely responsible for any underwriting discounts or
commissions applicable to its securities sold in the offering. Notwithstanding
the foregoing, Revenge and BYC will in good faith discuss BYC sharing a pro rata
portion of the offering expenses in connection with any registration of Warrant
Shares under Section 2(a) or (b) if such sharing is required to effect the
registration of securities in a particular jurisdiction and the managing
underwriter advises Revenge in writing that, in its opinion, the registration of
securities in that jurisdiction is necessary to assure a successful offering.

         (e) REGISTRATION PROCEDURES. If and whenever Revenge is required to use
reasonable efforts to effect the registration of any Warrant Shares under the
Securities Act as provided in Sections 2(a) and (b), Revenge will promptly:

         (1)      prepare and file with the SEC a registration statement with
                  respect to such Warrant Shares and use reasonable efforts to
                  cause such registration statement to become effective;

         (2)      prepare and file with the SEC such amendments and supplements
                  to such registration statement and the prospectus used in
                  connection therewith as may be necessary to keep such
                  registration statement effective for a period up to 180 days
                  and to comply with the provisions of the Securities Act with
                  respect to the disposition of all securities covered by such
                  registration statement until such time as all of such
                  securities have been disposed of in accordance with the
                  intended methods of disposition by BYC as set forth in such
                  registration statement;

         (3)      furnish to BYC such number of conformed copies of such
                  registration statement and of each such amendment and
                  supplement thereto (in each case including all exhibits), such
                  number of copies of the prospectus contained in such
                  registration statement (including each preliminary prospectus
                  and any summary prospectus), in conformity with the
                  requirements of the Securities Act, and such other documents,
                  as BYC may reasonably request in order to facilitate the
                  disposition of the Warrant Shares by BYC; provided, however,
                  that BYC and Revenge shall share equally all costs of printing
                  and delivering preliminary and final prospectuses in
                  connection with any registration of Warrant Shares under
                  Section 2(a);

         (4)      use its reasonable efforts to register or qualify such
                  securities covered by such registration statement under such
                  other securities or blue sky laws of such jurisdictions as BYC
                  may reasonably request, and do any and all other acts and
                  things which may be reasonably necessary or advisable to
                  enable BYC to consummate the disposition in such jurisdictions
                  of the Warrant Shares owned by BYC, except that Revenge will
                  not for any such purpose be required to qualify generally to
                  do business as a foreign corporation in any jurisdiction
                  wherein it is not so qualified, or to consent to general
                  service of process in any such jurisdiction;

         (5)      notify BYC at any time when a prospectus relating to its
                  Warrant Shares is required to be delivered under the
                  Securities Act of the happening or any event as a result of
                  which the prospectus included in such registration statement,
                  as then in effect, is known by Revenge to include an untrue
                  statement of material fact or to omit to state any material
                  fact required to be stated therein or necessary to make
                  statements therein not misleading in the light of the
                  circumstances then existing (provided that the period during
                  which such a condition may occur shall not be permitted by the
                  Company to persist for longer than 30 days nor shall two or
                  more



                                       4
   7

                  such periods be permitted by the Company to persist for an
                  aggregate of longer than 60 days during the term of such
                  registration), and promptly prepare, file and furnish to BYC a
                  reasonable number of copies of a supplement to, or an
                  amendment of, such prospectus as may be necessary so that, as
                  delivered to the purchasers of such securities, such
                  prospectus shall not include an untrue statement of a material
                  fact or omit to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading in the light of the circumstances then existing;
                  and

         (6)      advise BYC as to the time when such registration statement
                  becomes effective and as to the issuance by the SEC of any
                  stop order suspending the effectiveness of such registration
                  statement or the institution of any proceedings for that
                  purpose, and use reasonable efforts to prevent the issuance of
                  any such stop order and to obtain as soon as possible the
                  lifting thereof, if issued.

BYC will furnish to Revenge such information regarding BYC and the distribution
of the Warrant Shares as Revenge may from time to time reasonably request.

         (f) TAG-ALONG RIGHTS. If at any time Revenge proposes to sell
securities representing, or convertible into or exchangeable for, more than 20%
of its then outstanding Common Stock to a third party, other than pursuant to a
registered public offering under the Securities Act or a bona fide business
acquisition, then Revenge will give written notice to BYC. BYC may, upon giving
written notice to Revenge within 20 business days after receipt of Revenge's
notice, participate in such sale at the same price and upon the same terms and
conditions as are applicable to Revenge in such transaction. BYC may sell up to
the lesser of (i) one third of the total number of shares proposed to be sold by
Revenge, or (ii) all of the Warrant Shares. If BYC gives timely notice under
this Section 2(f), then Revenge will require as a condition precedent to
consummating the purchase of shares from Revenge, that the purchaser purchase
the Warrant Shares that BYC is entitled to sell under this Section 2(f), and
Revenge will not complete its sale to the purchaser if the purchaser fails to
satisfy such condition. The purchaser's purchase of the Warrant Shares be on
terms no less favorable than those set forth in Revenge's notice. referred to in
the second preceding sentence.

         (g) RESTRICTIONS ON BYC'S RIGHTS. Notwithstanding any provision of this
Section 3, BYC shall not have any demand registration rights under Section 3(a)
or tag-along rights under Section 2(f) at any time in which BYC could sell the
Warrant Shares it holds under Rule 144 or in another transaction exempt from
registration during the following 180 days.

3.       Fees.
         -----

         (a) Revenge will pay BYC a fee of 1% of its total revenues from all
Blackfin Sales sources for the period from April 1, 1999 to June 30, 1999 and 1%
of its total revenues from June 30, 1999 to April 30, 2002 Not to include the
sale of the assets listed in the security agreement with Finova Capital. The fee
will be due and payable quarterly by wire transfer to BYC's designated account
in United States dollars or acceptable securities within 30 days following each
calendar quarter during the applicable term, beginning with the year ending June



                                       5
   8

30, 1999. Revenge will simultaneously with each such payment furnish BYC the
quarterly financial statements described in Section 6(e), together with such
other information as BYC may from time to time reasonably request.

         (b) Revenge will maintain complete, clear and accurate records in
sufficient detail to enable the fees payable under this Section 3 to be
determined or audited, and Revenge will retain such records, and make them
available for inspection at any time, for a period of four years. BYC may
designate independent certified public accountants reasonably acceptable to
Revenge to audit, on a confidential basis, any fee certificates delivered or due
to BYC pursuant to this Section 3, provided that no more than two such audits
may be conducted during any 12-month period. Revenge will give the accountants
reasonable access to its facilities, as well as the opportunity to inspect at
such facilities all records that are reasonably necessary for the accountants to
determine if the fees have been properly calculated. The accountants will not
disclose any financial information but will only state that the calculated fees
were correct or that Revenge has correctly paid, overpaid or underpaid the fees.
If the accountants determine that Revenge has underpaid the fees, then Revenge
will promptly pay BYC the amount of the underpayment, together with interest
calculated from the date such amount was originally due at the rate of 12% per
annum or the maximum amount permitted by applicable law, if lower, by wire
transfer to BYC's designated account in United States dollars. If the accountant
determines that Revenge has overpaid the fees, then Revenge will receive a
credit in the amount of such overpayment on its next quarterly payment. BYC will
bear the costs of the audit unless the accountants determine that Revenge has
underpaid the fees by ten percent or more, in which case Revenge will bear such
costs.

4. REPRESENTATIONS AND WARRANTIES OF REVENGE. Revenge hereby represents and
warrants to BYC on the date hereof and on each Exercise Date (as defined in the
Warrant) as follows:

         (a) Revenge has been duly incorporated and is validly existing in good

         (c) Revenge has full corporate power and authority necessary to execute

                  notice or the lapse of time or both would be reasonably likely
                  to constitute a default) under (i) the Certificate of
                  Incorporation or by-laws of Revenge or any of its subsidiaries

                  determination of which Revenge is aware (after due inquiry) of
                  any court, governmental agency or body, or arbitrator having
                  jurisdiction over Revenge or any of its subsidiaries or any of
                  their respective properties or assets, (iii) the terms of any
                  bond, debenture, note or any other evidence of indebtedness,

                  indenture, lease, mortgage, deed of trust or other instrument
                  to which Revenge or any of its subsidiaries is a party, by
                  which Revenge or any of its subsidiaries is bound, or to which

         (2)      results in the creation or imposition of any lien, charge or
                  encumbrance upon (i) the Warrant or (ii) any of the properties
                  or assets of Revenge or any of its subsidiaries.

         (f) Revenge has authorized and reserved 1,500,000 shares of Common

adversely affect Revenge, or the execution or performance of its obligations
under this Agreement or the Warrant.

         (h) Revenge has timely filed all filings with the SEC under the
Securities Act or the Securities and Exchange Act of 1934, as amended (the

Revenge as a whole, contained any untrue statement of a material fact or omitted
to state any material fact

necessary in order to make the statements, in the light of the circumstances
under which they were made, not misleading.

5. REPRESENTATIONS AND WARRANTIES OF BYC. BYC hereby represents and warrants to
Revenge on the date hereof as follows:

         (a) BYC has been duly incorporated and is validly existing in good
standing under the laws of State of Delaware.

         (b) The execution, delivery and performance of this Agreement by BYC
have been duly authorized by all requisite corporate action; and no further
consent or authorization of BYC, its Board of Directors or its stockholders is
required. This Agreement has been duly executed and delivered by BYC and, when
duly authorized, executed and delivered by Revenge, will be a valid and binding
agreement, enforceable against BYC in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights generally and to
general principles of equity.

         (c) Subject to Section 2, BYC understands that the Warrant and the
Warrant Shares have not been registered under the Securities Act and may not be
re-offered or resold other than pursuant to such registration or an available
exemption therefrom.

         (d) BYC is an "accredited investor" as that term is defined in
Regulation D. BYC is acquiring the Warrant for its own account for investment
only and not with a view to, or for resale in connection with, the public sale
or distribution thereof except pursuant to sales registered under the Securities
Act or an exemption from registration thereunder.

6. COVENANTS. Revenge covenants and agrees with BYC as follows:

         (a) Following an initial public offering of Common Stock and for so
long as any portion of the Warrant remains outstanding, Revenge will use
reasonable efforts to (i) maintain the eligibility of the Common Stock for
quotation on NASDAQ National Market ("NASDAQ") or listing on a national or
regional securities exchange (as defined in the Exchange Act) and (ii) use
reasonable efforts to regain the eligibility of the Common Stock for quotation
on NASDAQ in the event that the Common Stock is delisted by NASDAQ or national
or regional securities exchange.

         (b) Revenge will (i) provide BYC with an opportunity to review and
comment on any public disclosure by Revenge of information regarding this
Agreement and the transactions contemplated hereby, (ii) promptly notify BYC if
there is any public disclosure by Revenge of material information regarding
Revenge or its financial condition, prospects or results of operation and (iii)
provide BYC with copies of all registration statements, annual reports,
quarterly reports, proxy materials and other filings with the SEC, NASDAQ and
any national or regional securities exchange on which the Common Stock is
listed.

         (c) Revenge will comply with the terms and conditions of the Warrant as
set forth in the Warrant (as duly amended from time to time by the parties
hereto).





                                       8
   11

         (d) For so long as any portion of the Warrant remains outstanding,
Revenge will at all times reserve and keep available, free from preemptive
rights, out of its authorized but unissued Common Stock, for issuance upon
exercise of such Warrant, the maximum number of Warrant Shares then so issuable.
If at any time the number of authorized but unissued shares of Common Stock is
not sufficient to effect the exercise of the Warrant for all the Warrant Shares
issuable thereunder, Revenge shall use reasonable efforts to increase its number
of authorized shares of Common Stock to such number of shares as shall be
sufficient to effect such exercise, including causing its Board of Directors to
call a meeting of stockholders and recommending such increase, and after
obtaining any such approval Revenge shall reserve for issuance to BYC the number
of shares of Common Stock required to effect such exercise.

         (e) Revenge will furnish BYC financial statements as follows: (i)
within 30 days after the end of each calendar quarter, financial statements
prepared and certified by management, and (ii) within 90 after the end of each
fiscal year, audited financial statements, prepared by certified public
accountants of national standing. The financial statements provided by Revenge
under this subsection (e) will be prepared in accordance with generally accepted
accounting principles, consistently applied, and will include all balance
sheets, cash flows and earnings statements, and other financial information
which BYC may from time to time reasonably request.

         (f) As long as the Warrant or any Warrant Shares are outstanding,
unless BYC otherwise consents in advance in writing:

         (1)      Revenge will continue to engage in business of the same
                  general type as conducted on the closing date and do or cause
                  to be done all things necessary to preserve, renew and keep in
                  full force and effect its legal existence and the rights,
                  licenses, permits, privileges and franchises material to the
                  conduct of its business.

         (2)      Revenge will not convey, sell, lease, assign, transfer or
                  otherwise dispose of any of its property, business or assets,
                  whether now owned or hereafter acquired, other than in the
                  ordinary course of business other than the manufacturing
                  assets know as Blackfin and Egret and Consolidated.

         (3)      Revenge will not enter into any transaction, including,
                  without limitation, any purchase, sale, lease or exchange of
                  property or the rendering of any service, with any affiliate
                  unless such transaction is (a) in the ordinary course of
                  Revenge's and such affiliate's business and (b) upon fair and
                  reasonable terms no less favorable to Revenge than it would
                  obtain in a comparable arm's length transaction with a person
                  which is not an affiliate.

7. LEGEND. BYC understands that the certificates or other instruments
representing the Warrant and, until such time as the Warrant Shares shall have
been sold pursuant to a registration under the Securities Act as contemplated by
this Agreement, the stock certificates representing the Warrant Shares shall
bear a restrictive legend in substantially the following form (and a
stop-transfer order may be placed against transfer of such certificates or other
instruments):




                                       9
   12

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
         SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
         MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
         ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
         SAID ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL
         IN FORM, SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE ISSUER THAT
         REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE
         SECURITIES LAWS.

The legend set forth above shall be removed and Revenge shall issue a
certificate without such legend to any holder of the Warrant Shares if, unless
otherwise required by state securities laws, (i) the same are sold pursuant to
an effective registration statement under the Securities Act, or (ii) in
connection with a sale transaction, such holder provides Revenge with an opinion
of counsel, in form, substance and scope reasonably acceptable to Revenge, to
the effect that a public sale, assignment or transfer thereof maybe lawfully
effected without registration under the Securities Act, or (iii) such holder
provides Revenge with assurances reasonably satisfactory to Revenge that the
same may be publicly sold pursuant to Rule 144 without restriction.

8. FEES AND EXPENSES. Except as otherwise provided in this Agreement or the
Warrant, each party will be bear its own legal fees and expenses incurred in
connection with preparing this Agreement and the related transactions.

9.       INDEMNIFICATION.

         (a) INDEMNIFICATION OF BYC. Revenge hereby agrees to indemnify BYC and
each of its officers, directors, employees, agents and affiliates and each
person that controls (within the meaning of Section 20 of the Exchange Act) any

         (2)      any material inaccuracy in or material breach of the
                  representations and warranties of Revenge made in this
                  Agreement or the Warrant; or

         (3)      any untrue statement or alleged untrue statement of any
                  material fact contained in any registration statement,
                  prospectus, or any amendment or supplement thereto, or any
                  related preliminary prospectus filed by or on behalf of
                  Revenge, or the omission or alleged omission to state therein
                  a material fact required to be stated therein or necessary to
                  make the statements therein not misleading; except to the
                  extent that any such claim, demand, action, liability,
                  damages, loss, cost, settlement, disposition or expense arises
                  out of or is based upon an untrue

                  omission made in any such document or amendment or supplement
                  thereto, in reliance upon and in conformity with written
                  information furnished to Revenge by, or on behalf of, BYC
                  specifically for use therein.

         (b) INDEMNIFICATION OF REVENGE. BYC hereby agrees to indemnify Revenge
and each of its officers, directors, employees, agents and affiliates and each
person that controls (within the meaning of Section 20 of the Exchange Act) any
of the foregoing persons against any claim, demand, action, liability, damages,
loss, cost, settlement, disposition or expense (including, without limitation,

         (2)      any material inaccuracy in or material breach of the
                  representations and warranties of BYC made in this Agreement
                  or the Warrant; or

         (3)      any untrue statement or alleged untrue statement of any
                  material fact contained in any registration statement,
                  prospectus, or any amendment or supplement thereto, or any
                  related preliminary prospectus filed by or on behalf of
                  Revenge, or the omission or alleged omission to state therein
                  a material fact required to be stated therein or necessary to
                  make the statements therein not misleading, but only to the to
                  the extent that any such claim, demand, action, liability,
                  damages, loss, cost, settlement, disposition or expense arises
                  out of or is based upon an untrue statement or alleged untrue
                  statement or omission or alleged omission made in any such
                  document or amendment or supplement thereto, in reliance upon
                  and in conformity with written information furnished to
                  Revenge by, or on behalf of, BYC specifically for use therein.

Party") will notify the party from whom such indemnification is sought (the
"Indemnifying Party") in writing of the relevant event or proceeding and the
facts constituting the basis for such claim in reasonable detail. Upon delivery
of such notice, such Indemnified Party will take all reasonable steps to

such event or proceeding. Such Indemnifying Party shall have the right to retain
counsel of its choice in connection with such event or proceeding and to
participate at its own expense in the defense of any such event or proceeding.
An Indemnifying Party will not, without the prior written consent of the
applicable Indemnified Parties (which consent may not be unreasonably withheld),
