due, Ecesis shall pay the cost of such examination plus a penalty equal to
twenty-five percent (25%) of the underpayment. Any payment not made on or before
the due date shall accrue interest at a rate equal to one percent (1%) per
calendar month or, if less, the maximum rate permitted under applicable law.

and all comments to the Proxy Statement received from the SEC upon receipt
thereof. As promptly as practicable after the filing of the final Proxy
Statement with the SEC, Polychem and Shareholder shall use their reasonable
efforts to cause the Proxy Statement to be disseminated to the stockholders of
Shareholder.

     6.6 Shareholders' Meeting. Shareholder shall take all necessary steps in
accordance with its articles of incorporation and by-laws to call, give notice
of, convene and hold the Shareholders' Meeting as soon as practicable after the
final Proxy Statement is filed and disseminated to the stockholders of
Shareholder for the purpose of approving this Agreement and the sale of the
Assets and for such other purposes as may be necessary. Unless this Agreement
shall have been validly terminated as provided herein, the Board of Directors of
Shareholder will (i) recommend to its stockholders the approval of this
Agreement, the sale of the Assets and the transactions contemplated thereby and
any other matters to be submitted to the stockholders of Shareholder in
connection therewith, to the extent that such approval is required by applicable
law in order to consummate such transactions, and (ii) use its reasonable, good
faith efforts to obtain the approval of its stockholders of this Agreement, the
sale of the Assets and the transactions contemplated thereby and to solicit from
its stockholders proxies in favor of such matters.

     6.7 Fiduciary Duty. Notwithstanding any other provision of this Agreement,
if the Board of Directors of Shareholder determines in good faith that it is
required to do so in order to comply with its fiduciary duties, the Board of
Directors may withdraw or modify its recommendation to the stockholders of
Shareholder and cause Shareholder or Polychem to take such action with respect
to the matters set forth in Sections 6.5 and 6.6 hereof as the Board of
Directors shall in good faith deem reasonably necessary or appropriate in
connection with such determination.

                                       10

     6.8 Use of Name. At the Closing, Polychem shall cause an amendment to its
certificate of incorporation to be filed with the Secretary of State of the
Commonwealth of Pennsylvania changing its name to a name bearing no resemblance
and that is not confusingly similar to "Polychem." After the Closing, neither
Polychem nor Shareholder shall use or permit any of its or their Affiliates to
use such name or any variants or derivatives thereof or any other name that is
confusingly similar. Polychem shall execute and deliver to Ecesis, at or before
the Closing, all consents requested by Ecesis to enable Ecesis to use such name
and shall otherwise cooperate with Ecesis in connection therewith.

     6.9 Commercially Reasonable Efforts. Between the date of this Agreement and
the Closing Date, Ecesis, Polychem and Shareholder will use commercially
reasonable efforts to cause the conditions in Articles VII and VIII to be
satisfied.

                ARTICLE VII. CONDITIONS TO OBLIGATIONS OF ECESIS

     The obligations of Ecesis to purchase the Assets are subject to the
satisfaction, at or before the Closing, of each of the following conditions:

     7.1 Representations and Warranties. The representations and warranties of
Polychem and Shareholder contained herein, and the statements contained in any
schedule, instrument, list, certificate or writing delivered by Polychem and
Shareholder pursuant to this Agreement shall be true, complete and accurate in
all material respects as of the date when made and, as of the Closing Date as
though such representations and warranties were made at and as of such dates,
except for any changes expressly permitted by this Agreement.

     7.2 Performance. Polychem and Shareholder shall have performed and complied
in all material respects with all covenants, agreements, obligations and
conditions required by this Agreement to be performed or complied with by
Polychem and Shareholder at or prior to the Closing. Polychem and Shareholder
agree that the Assets are unique and that damages would not be an adequate
remedy for their breach of this Agreement. Therefore, in the event that Polychem
and/or Shareholder fail to refuse to satisfy conditions to Closing, or to
otherwise perform their obligations hereunder, Polychem and Shareholder agree
that Ecesis may enforce specific performance of this Agreement by appropriate
proceedings in any court.

     7.3 No Proceeding or Litigation. There shall not be threatened, instituted
or pending any suit, action, investigation, inquiry or other proceeding by or
before any court or governmental or other regulatory or administrative agency or
commission requesting or looking toward an order, judgment or decree that (a)
restrains or prohibits the consummation of the transactions contemplated hereby,
(b) could have a material adverse effect on Ecesis' ability to exercise control
over or manage the Assets after the Closing or (c) could have a Material Adverse
Effect.

                                       11
<PAGE>

     7.4 Officers' Certificate. Polychem shall have delivered to Ecesis a
certificate, dated as of the Closing Date, executed by its Chief Executive
Officer and Chief Financial Officer certifying the fulfillment of the conditions
specified in Sections 7.1, 7.2, and 7.3.

     7.5 Secretary's Certificates. Each of Polychem and Shareholder shall have
delivered to Ecesis a certificate, dated as of the Closing Date, executed by its
Secretary, certifying as to its certificate of incorporation, bylaws, or other
governing documents and resolutions adopted by its board of directors with
respect to the transactions contemplated hereby.

     7.6 Documents. The Related Instruments and all other documents to be
delivered by Polychem and Shareholder to Ecesis at the Closing shall have been
so delivered and shall be satisfactory in form and substance to Ecesis.

     7.7 Consents and Approvals. All licenses, permits, consents, approvals and
authorizations of all third parties and governmental bodies and agencies shall
have been obtained that are necessary in connection with (a) the execution and
delivery of this Agreement or the Related Instruments, (b) the consummation of
the transactions contemplated hereby or thereby or (c) the ownership and
operation by Ecesis of the Assets, and copies of all such licenses, permits,
consents, approvals and authorizations shall have been delivered to Ecesis.

     7.8 Shareholder Approval. The stockholders of Shareholder shall have
approved this Agreement, the sale of the Assets to Ecesis and the transactions
contemplated thereby.

                    ARTICLE VIII. CONDITIONS TO OBLIGATIONS
                           OF POLYCHEM AND SHAREHOLDER

     The obligations of Polychem and Shareholder under this Agreement are
subject to the satisfaction, at or before the Closing, of each of the following
conditions:

     8.1 Representations and Warranties. The representations and warranties of
Ecesis contained herein shall be true, complete and accurate in all material
respects as of the date when made and at and as of the Closing Date as though
such representations and warranties were made at and as of such date, except for
any changes expressly permitted by this Agreement. Notwithstanding anything to
the contrary set forth herein, if as of the Closing Date either party knew, or
through the exercise of reasonable diligence should have known, of any breach by
the other party of a representation or warranty and proceeds with Closing, such
breach shall be deemed waived.

     8.2 Performance. Ecesis shall have performed and complied in all material
respects with all covenants, agreements, obligations and conditions required by
this Agreement to be so performed or complied with by it at or prior to the
Closing, including without limitation timely payment of royalties.

     8.3 No Injunction. On the Closing Date, there shall be no effective
injunction, writ, preliminary restraining order or other order issued by a court
of competent jurisdiction restraining or prohibiting the consummation of the
transactions contemplated hereby.

                                       12
<PAGE>

     8.4 Shareholder Approval. The stockholders of Shareholder shall have
approved this Agreement, the sale of the Assets to Ecesis and the transactions
contemplated thereby.

                            ARTICLE IX. TERMINATION

     9.1 Termination Events. This Agreement may, by notice given prior to or at
the Closing, be terminated:

     (a) By either Ecesis or Polychem if a material breach of any provision of
this Agreement has been committed by the other party and such breach has not
been waived;

     (b) By either Ecesis or Polychem if the Board of Directors of Shareholder
determines in good faith that its fiduciary duties require that it refrain from
recommending (or withdraw or modify adversely to Ecesis its prior
recommendation) that the stockholders of Shareholder approve the transactions
contemplated by this Agreement;

     (c) (i) by Ecesis if any of the conditions in Article VI or VII has not
been satisfied as of the Closing Date or if satisfaction of such a condition is
or becomes impossible (other than through the failure of Ecesis to comply with
its obligations under this Agreement) and Ecesis has not waived such condition
on or before the Closing Date; or (ii) by Polychem, if any of the conditions in
Article VIII has not been satisfied of the Closing Date or if satisfaction of
such a condition is or becomes impossible (other than through the failure of
Polychem or Shareholder to comply with its obligations under this Agreement) and
Polychem has not waived such condition on or before the Closing Date;

     (d) By mutual consent of Ecesis and Polychem; or

     (e) By either Ecesis or Polychem if the Closing has not occurred (other
than through the failure of any party seeking to terminate this Agreement to
comply fully with its obligations under this Agreement) on or before 120 days
from the date hereof or such later date as the parties may agree upon.

     9.2 Effect of Termination. Each party's right of termination under Section
9.1 is in addition to any other rights it may have under this Agreement or
otherwise, and the exercise of a right of termination will not be an election of
remedies. If this Agreement is terminated pursuant to Section 9.1, all further
obligations of the parties under this Agreement will terminate, except that the
obligations in Section 11.2 will survive; provided, however, that if this
Agreement is terminated by a party because of the breach of the Agreement by the
other party or because one or more of the conditions to the terminating party's
obligations under this Agreement is not satisfied as a result of the other
party's failure to comply with its obligations under this Agreement, the
terminating party's right to pursue all legal remedies will survive such
termination unimpaired. If the Closing does not occur (a) Ecesis' aggregate
liability for damages to Polychem or Shareholder for any breach of this
Agreement shall be limited to the amount of the Deposit plus reasonable
attorneys fees and costs and (b) the aggregate liability of Polychem and
Shareholder to Ecesis for damages for any breach of this Agreement shall be
limited to $150,000 plus reasonable attorneys fees and costs.

                  ARTICLE X. INDEMNIFICATION AND CONTRIBUTION

     10.1 Survival of Representations and Covenants. All representations and
warranties made by any party to this Agreement or pursuant hereto shall survive
the Closing hereunder and any investigation made by or on behalf of any party
hereto for a period of two years following the Closing Date; provided, however,
that in the case of fraud, all such representations and warranties shall survive
indefinitely and provided that the representations and warranties under Sections
4.1, 4.2, 4.3(i) and (iii), 4.8, 5.1, 5.2, 5.3(i) and (iii) and 5.6 shall
survive indefinitely. Subject to Section 9.2, the Closing shall not have the
effect of terminating any covenant or obligations of the parties hereto which
are applicable after the Closing.

     10.2 Indemnification.

     (a) Subject to the terms and conditions of this Article X, Polychem and
Shareholder shall indemnify, defend and hold harmless Ecesis from and against
all demands, claims, actions or causes of action, assessments, losses, damages,
liabilities, costs and expenses, including interest, penalties and reasonable
attorneys' fees and expenses (collectively, "Damages"), asserted against,
resulting to, imposed upon or incurred by Ecesis, directly or indirectly, by
reason of or resulting from (i) other than the Assumed Liabilities, any
liabilities or obligations of Polychem (whether absolute, accrued, contingent or
otherwise) existing as of the Closing or arising out of facts, conditions or
circumstances existing at or prior thereto, whether or not such liabilities,
obligations or claims were known at the time of the Closing, including without
limitation, any liability or obligation arising out of the ownership of the
Assets or the conduct of the Business prior to the Closing; (ii) a breach of any
representation, warranty, covenant or agreement of Polychem contained in or made
pursuant to this Agreement or any Related Instrument; and (iii) any claim
asserted against Ecesis or any of its Affiliates with respect to any taxes
relating to Polychem's operations or properties (collectively, "Ecesis'
Claims").

     (b) Subject to the terms and conditions of this Article X, Ecesis shall
indemnify, defend and hold harmless Polychem and Shareholder from and against
all Damages asserted against, resulting to, imposed upon or incurred by
Polychem, directly or indirectly, by reason of or resulting from (i) the Assumed
Liabilities; and (ii) a breach of any representation, warranty, covenant or
agreement of Ecesis contained in or made pursuant to this Agreement
(collectively, "Polychem's Claims") (Ecesis' Claims and Polychem's Claims
collectively referred to as "Claims," each, a "Claim").

     (c) Notwithstanding any provision in this Article X to the contrary, no
party hereto shall be required to indemnify any Person pursuant to this Article
X unless and until the aggregate amount of Claims as to which indemnification
would be required from such party (but for the provisions of this Section
10.2(c)) exceeds $25,000 (the "Indemnity Threshold"), and thereafter such party
shall be required in the manner and to the extent otherwise provided in this
Article X, to indemnify any Person and to pay all amounts required to be paid by
such party in respect of such Claims, irrespective of the Indemnity Threshold.
The amount of each Claim shall be adjusted to provide the Indemnifying Party (as
defined below) the benefit of (i) any insurance coverage provided with respect
to a Claim and (ii) any tax benefit realized by the Indemnified Party (as
defined below) with respect to a Claim.

                                       14
<PAGE>

     10.3 Third Party Claims. The obligations and liabilities of Ecesis, on the
one hand, and Polychem and Shareholder, on the other hand, as indemnifying
parties (each, an "Indemnifying Party") to indemnify Polychem and the
Shareholders and Ecesis, respectively (each, an "Indemnified Party"), under
Section 10.2 with respect to Claims made by third parties shall be subject to
the terms and conditions set forth in this Section 10.3. The Indemnified Party
shall give written notice to the Indemnifying Party of any Claim with respect to
which it seeks indemnification promptly after the discovery by such party of any
matters giving rise to such Claim for indemnification; provided that the failure
of any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under Section 10.2 unless it shall have
been prejudiced by the omission to provide such notice. In case any action,
suit, claim or proceeding is brought against an Indemnified Party, the
Indemnifying Party shall be entitled to participate in the defense thereof and,
to the extent that it may wish, to assume the defense thereof, with counsel
reasonably satisfactory to the Indemnified Party. After notice from the
Indemnifying Party of its election so to assume the defense thereof, the
Indemnifying Party will not be liable to the Indemnified Party under Section
10.2 for any legal or other expense subsequently incurred by the Indemnified
Party in connection with the defense thereof; provided, however, that (a) if the
Indemnifying Party shall elect not to assume the defense of such claim or action
or (b) if the Indemnified Party reasonably determines that there may be a
conflict between the positions of the Indemnifying Party and the Indemnified
Party in defending such claim or action, then separate counsel shall be entitled
to participate in and conduct such defense, and the Indemnifying Party shall be
liable for any reasonable legal or other expenses incurred by the Indemnified
Party in connection with such defense. The Indemnifying Party shall not be
liable for any settlement of any action, suit, claim or proceeding effected
without its written consent, which consent shall not be unreasonably withheld or
delayed. The Indemnifying Party shall not, without the Indemnified Party's prior
written consent, settle or compromise any action, suit, claim or proceeding to
which the Indemnified Party is a party or consent to entry of any judgment in
respect thereof, unless the Indemnifying Party discharges or assumes any and all
liabilities or obligations in connection with such settlement and the settlement
(i) includes an unconditional release of the Indemnified Party from all
liability, (ii) requires only the payment of money and (iii) does not include an
admission of guilt.

     10.4 Contribution. In the event that the foregoing indemnity is unavailable
to an Indemnified Party for any reason, the Indemnifying Party shall contribute
to any such Damages and shall do so in such proportion as is appropriate to
reflect the relative fault of each party in connection with the conduct that
resulted in the Damages. The parties agree that it would not be just or
equitable if contributions were determined by pro rata allocation or by any
other method of allocation that does not take account of relative fault and
other equitable considerations.

     10.5 Remedies Cumulative. Except as expressly provided in this Agreement,
the remedies provided herein shall be cumulative and shall not preclude
assertion by any party hereto of any other rights or the seeking of any other
remedies against any other party hereto.

                    ARTICLE XI. NONCOMPETE AND NONDISCLOSURE

     11.1 Noncompetition. Polychem and the Shareholder covenant and agree that,
for a period of five (5) years after the Closing Date, Polychem and the
Shareholder shall not, anywhere in the world, directly or indirectly engage in,
assist or have an interest in (whether as

                                       15
<PAGE>

proprietor, partner, investor, lender, shareholder, member, officer, director or
any other type of owner or principal whatsoever), or enter into the employment
of or act as an agent for, or advisor or consultant to, any Person engaged in
the business of manufacturing, marketing and distributing products which compete
with the Products. For purposes hereof, the term "shareholder" shall not include
beneficial ownership of less than three percent (3%) of the combined voting
power of all issued and outstanding voting securities of a publicly-held
corporation whose stock is, or at the time of acquisition of such securities
was, traded on a major stock exchange or quoted on NASDAQ.

     11.2 Nondisclosure. Polychem and the Shareholder covenant and agree that
they will not at any time following disclose, directly or indirectly, or make
available to any Person, or in any manner use for their own benefit, any
Confidential Information or trade secrets relating to the Products or the
Business, including, without limitation, business strategies, operating plans,
acquisition strategies (including the identities of (and any other information
concerning) possible acquisition candidates), pro forma financial information,
market analysis, acquisition terms and conditions, personnel information,
product information (whether existing, former, or proposed), trade secrets,
sources of leads and methods of obtaining new business, know-how, customer lists
and relationships, supplier lists and relationships, manufacturing and
distribution methods or any other methods of doing and operating the Business,
or other non-public proprietary and confidential information relating to the
Business, except to the extent that such information (i) is obtained from a
third party whom the disclosing party has no reason to believe is bound by a
duty of confidentiality, (ii) relates to information that is or becomes
generally known to the public other than as a result of a breach of this
Agreement, or (iii) is required to be disclosed by law or judicial
administrative process (in which case prior to such disclosure the disclosing
party shall promptly provide prior written notice of such required disclosure to
Ecesis in order to afford Ecesis the opportunity to seek an appropriate
protective order preventing such disclosure).

     11.3 Injunctive Relief. Polychem and the Shareholder agree that any breach
of this Article XI by them will cause irreparable damage to the business of
Ecesis and that in the event of such breach Ecesis shall have, in addition to
any and all remedies of law, the right to an injunction, specific performance or
other equitable relief in any court of competent jurisdiction to prevent the
violation of his obligations hereunder. Nothing herein contained shall be
construed as prohibiting Ecesis from pursuing any other remedy available for
such breach or threatened breach. The prevailing party in any litigation arising
under this Article XI shall be entitled to recover his or its attorneys' fees
and expenses in addition to all other available remedies.

                           ARTICLE XII. MISCELLANEOUS

     12.1 Press Releases and Public Announcements. The parties shall cooperate
in the preparation of a joint press release to be issued following the Closing.
Unless required by law, Ecesis, on the one hand, nor Polychem or Shareholder, on
the other hand, shall issue any press release or make any public announcement
relating to the subject matter of this Agreement prior to the Closing without
the prior written approval of the other party.

     12.2 Confidentiality. Polychem, Shareholder and Ecesis shall hold, and
shall cause their respective members, employees, consultants and advisors to
hold, in strict confidence, unless compelled to disclose by judicial or
administrative process or by other requirements of

                                       16
<PAGE>

law, all documents and information concerning the other parties furnished to it
by any other party or its representatives in connection with the transactions
contemplated by this Agreement (except to the extent that such information shall
be shown to have been (a) previously known by the party to which it was
furnished, (b) in the public domain through no fault of such party or (c) later
lawfully acquired from other sources by the party to which it was furnished),
and each party shall not release or disclose such information to any other
person, except its auditors, attorneys, financial advisors, bankers and other
consultants and advisors in connection with the transactions contemplated by
this Agreement. Each party shall be deemed to have satisfied its obligation to
hold confidential information concerning or supplied by the other party if it
exercises the same care as it takes to preserve confidentiality for its own
similar information.

     12.3 Further Assurances. From time to time, at the request of Ecesis and
without further consideration, Polychem and Shareholder shall execute and
deliver to Ecesis such documents and take such other action as Ecesis may
reasonably request in order to consummate the transactions contemplated hereby
and to vest in Ecesis good and valid title to the Assets.

     12.4 Parties in Interest. This Agreement shall be binding upon, inure to
the benefit of, and be enforceable by the respective successors and permitted
assigns of the parties hereto. Except as otherwise expressly provided herein,
the rights and obligations of Ecesis hereunder may not be assigned without the
prior written consent of Polychem and Shareholder, and the rights and
obligations of Polychem and Shareholder hereunder may not be assigned without
the prior written consent of Ecesis.

     12.5 Entire Agreement. This Agreement, the exhibits, the schedules and
other writings among the parties hereto contain the entire understanding of the
parties with respect to the subject matter hereof and thereof and supersede all
prior understandings and agreements with respect to the subject matter hereof
and thereof, including without limitation, any and all term sheets between the
parties hereto.

     12.6 Amendments and Waivers. No consent hereunder may be given and no
provision hereof may be waived except by a written instrument signed by the
party to be charged with such consent or waiver. This Agreement may not be
amended except by a written instrument duly executed by all of the parties
hereto. Any amendment or waiver effected in accordance with this Section 12.6
shall be binding upon all of the parties hereto.

     12.7 Headings. The Article and Section headings contained in this Agreement
are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     12.8 Notices. All notices, claims, certificates, requests, demands and
other communications hereunder shall be in writing and shall be deemed to have
been duly given if delivered personally, mailed (registered or certified mail,
postage prepaid, return receipt requested) or by facsimile transmission with

     12.9 Governing Law; Jurisdiction. This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Pennsylvania,
without regard to its or any other jurisdiction's conflicts of laws principles.
Any legal action or proceeding with respect to this Agreement or for recognition
and enforcement of any judgment in respect hereof brought by any party hereto or
its successors or assigns shall be brought and determined in the federal or
state courts located in Philadelphia, Pennsylvania, and each party hereto
submits with regard to any such action or proceeding for itself and in respect
to its property, generally and unconditionally, to the exclusive jurisdiction of
such courts, and agrees that service of process in any such action or proceeding
shall be effective if mailed to such party at the address specified herein. To
the fullest extent permitted by law, each party hereto irrevocably waives, and
agrees not to assert, by way of motion, as a defense, counterclaim or otherwise,
in any action or proceeding with respect to this Agreement any claim that (a) it
is not personally subject to the jurisdiction of such courts for any reason, (b)
that it or its property is exempt or immune from jurisdiction of any court or
from any legal process commenced in such courts (whether through service of
notice, attachment prior to judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (c) the suit, action or
