pursuant to the Merger shall be a number of shares of FiberChem common stock
equal to (a) the number of Intrex common shares owned by Pandel at the time of
closing under this Agreement multiplied by the Intrex Exchange Ratio plus (b)
9,450,000 shares.

     The Intrex Exchange Ratio shall mean the ratio of (x) the aggregate number
of Intrex Class B shares deliverable to Intrex Participating Shareholders
pursuant to Section 3.8 of the Amended Arrangement Agreement including Intrex
Class B shares required to be deposited under the Pooling Agreement pursuant to
Section 3.8 of the Arrangement Agreement to (y) the aggregate number of Intrex
common shares held by Participating Intrex Shareholders immediately prior to the
Closing of the Arrangement pursuant to the Arrangement Agreement.

         Upon delivery of the merger consideration to the Pandel Shareholders,
the Pandel Shareholders shall deposit under an escrow agreement (the "Merger
Consideration Escrow Agreement") among FiberChem, each Pandel Shareholder and an
escrow agent to be agreed upon by them a number of shares of FiberChem Common
Stock equal to the sum of (i) a portion of the merger consideration delivered to
the Pandel Shareholders pursuant to clause (a) of the first paragraph of this
Section 2.1 that bears the same ratio to the number of shares of FiberChem

number of Intrex Class B Shares deliverable to Intrex Participating Shareholders
pursuant to Section 3.8 of the Amended Arrangement Agreement including the
Intrex Class B Shares required to be deposited under the Pooling Agreement
pursuant to Section 3.8 of the Amended Arrangement Agreement, plus (ii) all of
the 9,450,000 shares of FiberChem Common Stock payable to the Pandel
Shareholders pursuant to clause (b) of the first paragraph of Section 2.1. The
shares of FiberChem Common Stock deposited under the Merger Consideration Escrow
Agreement are herein sometimes called the Merger Consideration Escrow Shares.
The Merger Consideration Escrow Agreement shall be in form and substance
satisfactory to the Pandel Shareholders, FiberChem and the escrow agent
thereunder and shall provide for the exercise of the voting rights of the Merger
Consideration Escrow Shares and the receipt of dividends and other distributions
thereon by the by the Pandel Shareholders so long as such shares remain on
deposit.


2.2  RELEASE OF THE MERGER CONSIDERATION.

     Upon each release of Pooled Shares pursuant to the Pooling Agreement, the
escrow agent under the Merger Consideration Escrow Agreement will release
therefrom to the former Pandel shareholders a number of shares of FiberChem
Common Stock equal to the sum of (a) a number of



shares of FiberChem Common Stock that bears the same ratio to the merger
consideration delivered pursuant to clause (a) of the first paragraph of Section
2.1 as the aggregate number of Pooled Shares so released pursuant to the Pooling
Agreement bears to the aggregate number of Intrex Class B Shares delivered to
Participating Intrex Shareholders pursuant to Section 3.8 of the Arrangement
Agreement including Intrex Class B shares required to be deposited under the
Pooling Agreement, plus (b) upon each such release, 3,150,000 shares of
FiberChem Common Stock.

     If FiberChem does not have sufficient authorized shares of its Common Stock
at any time when it is required to deliver Common Stock as merger consideration,
FiberChem may deliver or cause to be delivered one one hundredth of a FiberChem
Participating Convertible Share, Pandel Series ("FiberChem Pandel Series Stock")
in lieu of each share of FiberChem Common Stock which it was obligated to
deliver. The FiberChem Pandel Series Stock shall be designated by FiberChem's
Board of Directors from FiberChem's authorized, undesignated shares of preferred
stock and the Certificate of Designation therefor shall be in the form
heretofore furnished to Pandel and the Principal Shareholder.

2.3  COMPUTATION AND DELIVERY OF THE INITIAL MERGER CONSIDERATION.

     The Acquired Company owns on the date hereof and will own at all times
through the Closing 2,089,000 Intrex Common Shares. The initial merger

Shares.


2.4  OPEN ISSUES ESCROW SHARES.

     The Shareholders shall set-aside from the Merger Consideration for the
benefit of FiberChem and Pandel Mergerco such number of shares of FiberChem
Common Stock for such periods to be mutually negotiated specifically based upon
FiberChem determining during its due diligence prior to the Closing that there
are open issues for which an escrow needs to be created (the "Open Issues"; such
shares so set aside being called the "Open Issues Escrow Shares"). The Open
Issues Escrow Shares shall be held for the purpose of satisfying the Open Issues
(and for no other purpose). The Open Issues Escrow Shares delivered to in
satisfaction of any Open Issues shall be valued (for the purpose of satisfying
such Open Issues) at the greater of $_____ per share or the average selling
price per share for the ten trading days ending on the last trading day
preceding the date of delivery of such shares in satisfaction of the Open
Issues. The escrow of the Open Issues Escrow Shares shall terminate (and any or
property remaining therein shall be paid or distributed to the Shareholders)
following mutual resolution and satisfaction of the Open Issue or Issues with
respect to which the escrow was established.


2.5  CONVERSION OF SHARES; PAYMENT OF MERGER CONSIDERATION.

          (i)  All of the Merger Consideration shall be exchanged for all of the
validly issued, fully paid and non-assessable shares of common stock of the
Acquired Company. At the Effective Time, by virtue of the Merger and without any
action the part of any party hereto, each share of common stock of the Acquired
Company issued and outstanding immediately prior to the Effective Time shall be
converted into and shall represent the right to receive, upon surrender of the
certificate representing such shares, the proportion of the Merger Consideration
allocable to it.

          (ii) Each share of the common stock of Pandel Mergerco issued and
outstanding immediately prior to the Effective Time shall continue to be issued
and outstanding.

          (iii) Until surrendered, each outstanding certificate which prior to
the Effective Time




represented one or more shares of common stock of the Acquired Company shall be
deemed upon the Effective Time for all purposes to represent only the right to
receive the Merger Consideration. No interest will be paid or accrued on the
Merger Consideration upon the surrender of the certificate or certificate
representing such shares, except as specifically provided herein. With respect
to any certificate for common stock of the Acquired Company that has been lost
or destroyed, FiberChem shall direct distribution of the Merger Consideration
attributable to such certificate upon receipt of a surety bond or other adequate
indemnity as required in accordance with FiberChem's standard policy, and
evidence reasonably satisfactory to FiberChem of ownership of the shares
represented thereby. After the Effective Time, no transfer of the shares of
common stock of the Acquired Company outstanding immediately prior to the
Effective Time shall be made on the stock transfer books of the Surviving
Corporation.

          (iv) At least ten days prior to the Effective Time, FiberChem shall
cause to be delivered or mailed to each Shareholder a form of letter of
transmittal and instructions for use in effecting the surrender of the
certificates which, immediately prior to the Effective Time, represented shares
of common stock of the Acquired Company in exchange for the Merger
Consideration. Upon surrender at or after the Effective Time of such
certificates, together with such letter of transmittal duly executed and
completed in accordance with the instructions thereto, and such other documents
as may be reasonably requested, FiberChem shall direct that the Merger
Consideration be transferred to the persons entitled thereto as provided herein.

          (v)  In the event FiberChem changes the number of shares of FiberChem
Common Stock issued and outstanding prior to the Effective Time as a result of a
stock split, stock dividend or other similar recapitalization, and the record
date thereof (in the case of a stock dividend) or the effective date thereof (in
the case of a stock split or similar recapitalization for which a record date is
not established) shall be prior to the Effective Time, the amount of the Merger
Consideration shall be proportionately adjusted.

          (vi) Any Shareholder who shall have dissented from the Merger in
accordance with applicable state law, and who has properly exercised such
Shareholder's right to demand payment of the value of the Shareholder's shares
of the Acquired Company (the "Dissenting Shares") shall thereafter have only
such rights, if any, as are provided a dissenting shareholder under applicable
state law and shall have no rights under this SECTION 2.5; provided, however,
that if such Shareholder shall withdraw the demand for such appraisal or shall
become ineligible for such appraisal, then such Shareholder's Dissenting Shares
automatically shall cease to be Dissenting Shares and shall be converted into
and represent only the right to receive the Merger Consideration provided for in
this Section upon surrender of the certificate representing the Dissenting
Shares.

2.6  LOCK-UP OF FIBERCHEM COMMON STOCK.

     On or before the Closing the Lock-Up Agreement contemplated by Section 3.4
of the Arrangement Agreement shall have been executed and delivered.

2.7  REGISTRATION RIGHTS.

     (i)  If any or all of the shares of FiberChem Common Stock issued to the
former Pandel shareholders pursuant to the Merger (collectively the "REGISTERED
SHARES") are not eligible for sale in accordance with the volume and manner of
sale requirements of Rule 144 without registration, FiberChem shall file a
registration statement (the "REGISTRATION STATEMENT"), on Form S-4 or such




other appropriate form not later than 90 days after the Effective Time to
register the Registered Shares.


     (ii) In the event that any of the Registered Shares cannot be sold pursuant
to the Registration Statement or are not eligible for sale pursuant to Rule 144,
subject to the volume and manner of sale requirements of Rule 144, commencing
one year from the Closing Date (the "REGISTRATION CONDITIONS"), the
Shareholders, acting together with the Participating Intrex Shareholders
pursuant to Section 3.6 of the Arrangement Agreement, shall have the demand
registration rights provided in this Section 2.7. If at any time during the
period commencing upon the expiration of the No-Sale Period (as such term is
defined in the Lock-Up Agreement attached as Exhibit 3.4 to the Arrangement
Agreement) and ending two years thereafter, Registration Conditions exist,
FiberChem covenants and agrees with the Shareholders that, upon written request
of the then holder(s) of at least 25% of the remaining shares of FiberChem
Common Shares, FiberChem will file with the SEC as promptly as practicable and,
in any event, within 45 days after receipt of such written request, on one
occasion at FiberChem's sole expense, a registration statement (the "DEMAND
REGISTRATION STATEMENT") and, together with the Registration Statement, on a
form which would be available for the resale of the FiberChem Common Shares by
the Shareholders under the Securities Act, registering or qualifying the
FiberChem Common Shares requested to be so registered for sale. Such request
shall specify the shares of FiberChem Common Shares intended to be sold and the
intended method of disposition. FiberChem shall not, without the consent of the
Principal Shareholder, grant to any person registration rights that would
entitle such holders to include any securities of FiberChem in the Demand
Registration Statement.

     (iii) FiberChem will use its best efforts, through its officers, directors,
auditors and counsel in all matters necessary or advisable, to file and cause to
become effective the Registration Statements as promptly as practicable and to
maintain the effectiveness of the Registration Statements for a period of two
years thereafter, subject to subparagraph (v) below.

     (iv) FiberChem shall notify each Shareholder upon discovery that, or upon
the happening of any event as a result of which, the prospectus included in any
of the Registration Statements includes an untrue statement of a material fact
or omits to state any material fact required to be stated therein or necessary
to make the statements therein not misleading in the light of the circumstances
under which they were made; and, at the request of any Shareholder, FiberChem
shall promptly prepare and furnish to each Shareholder a reasonable number of
copies of a supplement or an amendment to such prospectus as may be necessary.

     (v)  FiberChem shall prepare and file with the SEC such amendments and
supplements to the Registration Statements and the prospectuses contained
therein as may be necessary to keep the Registration Statements effective and to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by the Registration Statements until such time as all
shares of FiberChem Common Stock have been disposed of in accordance with the
intended methods of disposition by the Shareholders set forth in such
Registration Statements; provided, that FiberChem shall not be required to
maintain the effectiveness of any Registration Statement as to any shares of
FiberChem Common Stock that may then be sold by a Shareholder in accordance with
Rule 144.

     (vi) FiberChem shall furnish to each Shareholder such number of preliminary
and final prospectuses included in any of the Registration Statements and of
each such amendment and supplement thereto as such Shareholder may reasonably
request.

     (vii) FiberChem shall use its best efforts to file in a timely manner all
reports required to be



filed with the SEC pursuant to Section 13 of the SECURITIES EXCHANGE ACT OF
1934, as amended, and shall otherwise maintain its eligibility (at all times
when it is eligible) to use Form S-3 and comply with the public information
requirements of paragraph (c) of Rule 144.

     (viii) FiberChem shall indemnify and hold harmless the Shareholders against
any losses, claims, damages, liabilities, costs (including, without limitation,
the reasonable cost of preparation and attorney's fees) and reasonable expenses
(collectively, "Losses") arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any of the Registration
Statements or any prospectus or preliminary prospectus included therein or
arising out of or based upon 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 based solely upon information
furnished in writing to FiberChem by such Shareholders expressly for use
therein.

     (ix) In connection with any registration in which a Shareholder is
participating personally, and not in their capacity as an employee, officer or
director of FiberChem, such Shareholder shall furnish to FiberChem in writing
such information as FiberChem reasonably requests for use in connection
therewith and agrees to indemnify and hold harmless FiberChem, its directors,
officers, agents and employees and each person who controls FiberChem (within
the meaning of Section 15 of the Securities Act or Section 20 of the Securities
Exchange Act of 1934) from and against all losses arising out of or based upon
any untrue statement of a material fact contained in any of the Registration
Statements or any prospectus or preliminary prospectus included therein or
arising out of or based upon any omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, to
the extent, but only to the extent, that such untrue statement or omission is
contained in any information so furnished in writing by such Shareholder to
FiberChem expressly for use in such Registration Statement, prospectus or
preliminary prospectus and that such information was solely relied upon by
FiberChem in preparation of such Registration Statement, prospectus or
preliminary prospectus. In no event shall the liability of any Shareholder
hereunder be greater in amount than the dollar amount of the proceeds (net of
the payment of all expenses) received by such Shareholder upon the sale of
shares of FiberChem Common Stock giving rise to such indemnification obligation.

     (x)  FiberChem will pay all expenses of FiberChem and the Shareholders in
connection with the Registration Statement described in Section 2.7(i) and one
Demand Registration Statement described in Section 2.7(ii) above, in each
instance exclusive of any underwriting discount or commission and the fees and
expenses of Shareholders' legal counsel in connection with the sale of shares by
the Shareholders pursuant to such registration.

     (xi) FiberChem acknowledges that the registration rights provided in
this Section 2.7 are also for the benefit of any of the Shareholders'
permitted transferees.

     (xii) If after December 31, 2000, FiberChem does not deliver FiberChem
Common Shares upon conversion of FiberChem Pandel Series Stock issued pursuant
to this Agreement in lieu of shares of FiberChem Common Stock due to the failure
of FiberChem to have sufficient authorized common share capital to permit such
conversion, FiberChem shall file a registration statement (the "Pandel Series
Stock Registration Statement) on Form S-4 or such other appropriate form to
register the FiberChem Pandel Series Stock held by the Shareholders. Such Pandel
Series Stock Registration Statement shall be filed not later than 90 days after
the failure of FiberChem to issue FiberChem Common Shares upon such conversion.
The Shareholders shall have the same rights with respect to the Pandel Series
Stock Registration Statement as apply to the Registration Statement under
sections 2.7(ii) through (xi) above.




2.8  ABANDONED PROPERTY LAWS.

     Payment or delivery of any shares of FiberChem Common Stock shall be
subject to applicable abandoned property, escheat and similar laws and neither
FiberChem nor the Surviving Corporation shall be liable to any holder of shares

distributions with respect thereto or for any cash in lieu of fractional shares
which may be delivered to any public official pursuant to any abandoned
property, escheat or similar laws.

pending or, to the best of FiberChem's or Pandel Mergerco's knowledge, is
contemplated. Each of FiberChem and Pandel Mergerco has been duly organized and
is validly existing under the laws of the State of Delaware, has full corporate
power and authority to conduct its business as it is now being conducted and is
duly qualified to do business in each jurisdiction where the nature of the
property owned or leased, or the nature of the business conducted by it requires
such qualification.

activities and will have no subsidiaries and will conduct its operations only as

     ARTICLE 6 - SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

6.1  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

     All representations and warranties made by the Acquired Company, the
Principal Shareholder, FiberChem or Pandel Mergerco in this Agreement,
including without limitation all representations and warranties made in any
Exhibit or Schedule hereto or certificate delivered hereunder, shall survive
the Closing until            , 2001 (the "Survival Date"); provided, however,
that all representations and warranties made by the Acquired Company and the
Principal Shareholder in SECTIONS 4.1, 4.10 and 4.18, hereof shall survive
the Closing until and through three months after the expiration of the
applicable statute of limitations (the "Extended Survival Date").

6.2  INDEMNIFICATION BY PRINCIPAL SHAREHOLDER.

     As an inducement to FiberChem to enter into this Agreement, provided that
the Merger contemplated by this Agreement is closed, the Principal Shareholder
hereby agrees to indemnify, defend and hold harmless FiberChem and Pandel
Mergerco from and against all liabilities, losses, costs or damages whatsoever,
both monetary and non-monetary (including reasonable expenses and reasonable
fees of legal counsel) ("Claims") made prior to the Survival Date or the
Extended Survival Date, if applicable, arising out of or based upon the
inaccuracy in any material respect of any representation, warranty, covenant or
any other agreement or obligation, of the Acquired Company set forth in this
Agreement (except to the extent of any inaccuracy disclosed in writing to
FiberChem and Pandel Mergerco prior to the Closing Date), to the extent of the
Merger Consideration paid or payable to the Principal Shareholder. The Principal
Shareholder hereby waives any rights of contribution and/or indemnification from
the Acquired Company and/or the Surviving Corporation.

          Prior to the Closing, the foregoing indemnity shall be provided solely
by the Acquired Company and not the Principal Shareholder. However, once the
Closing has occurred, the Principal Shareholder shall not seek contribution from
the Acquired Company. The principal Shareholder shall have the right to pay
FiberChem, at his election, in cash or Escrow Shares or other shares of
FiberChem Common Stock, valued at $ per share for any payment made to FiberChem
under this ARTICLE 6.

6.3  INDEMNIFICATION BY FIBERCHEM AND PANDEL MERGERCO.

     Provided that the Merger contemplated by this Agreement is closed,
FiberChem and Pandel Mergerco hereby agree to indemnify, defend and hold
harmless the Shareholders from and against all Claims made prior to the Survival
Date arising out of or from or based upon the inaccuracy in any material respect
of any representation or warranty contained in Article 5 by FiberChem and Pandel
Mergerco, the non-performance by FiberChem and Pandel Mergerco in any material
respect of any covenant, agreement or obligation to be performed by FiberChem
and Pandel Mergerco under this Agreement, or any liabilities arising out of the
operation of the business of the Acquired Company by FiberChem and Pandel
Mergerco after the Closing Date.



6.4  DEFENSE OF CLAIMS.

     (i) Whenever any Claim shall arise for indemnification hereunder, the party
entitled to indemnification (the "Indemnitee") shall notify the indemnifying
party (the "Indemnitor") in writing within 30 days after the Indemnitee has
actual knowledge that it is entitled to indemnification of such Claim
constituting the basis for such Claim (the "Notice of Claim"). The Notice of
Claim shall specify all facts known to the Indemnitee giving rise to such
indemnification claim and the amount or an estimate of the amount of the
liability arising therefrom.

     (ii) If the facts giving rise to any such indemnification shall involve any
actual, threatened or possible Claim or demand by any person against the
Indemnitee, the Indemnitor shall be entitled (without prejudice to the right of
the Indemnitee to participate at its expense through co-counsel of its own
choosing) to contest or defend such Claim at its expense and through counsel of
its own choosing if it gives written notice of the intention to do so to the
Indemnitee within 10 days after receipt of the Notice of Claim; provided that
Indemnitor diligently prosecutes or defends such Claim.

     (iii) The Indemnitee shall not settle any claim which would give rise to
liability on the part of the Indemnitor under the indemnity contained in this
Section without the written consent of the Indemnitor, which consent shall not
unreasonably be withheld, conditioned or delayed. If a firm offer is made to
settle a Claim or litigation defended by the Indemnitee and the Indemnitor
refuses to accept such offer within 20 days after receipt of written notice from
the Indemnitee of the terms of such offer, then, in such event, the Indemnitee
shall continue to contest or defend such claim and shall be indemnified pursuant
to the terms hereof. If a firm offer is made to settle a Claim or litigation and
the Indemnitor notifies the Indemnitee in writing that the Indemnitor desires to
accept and agree to such settlement, but the Indemnitee elects not to accept or
agree to it, the Indemnitee may continue to contest or defend such Claim and, in
such event, the total maximum liability of the Indemnitor to indemnify or
otherwise reimburse the Indemnitee hereunder with respect to such Claim shall be
limited to and shall not exceed the amount of such settlement offer, plus
reasonable out-of-pocket costs and expenses (including reasonable attorneys'
fees and disbursements) to the date of notice that the Indemnitor desires to
accept such settlement.
