                   Hudson Technologies, Inc. and subsidiaries
                   Notes to Consolidated Financial Statements
General

Hudson Technologies, Inc., incorporated under the laws of New York on January
11, 1991, together with its subsidiaries (collectively, "Hudson" or the
"Company"), sells refrigerants and provides refrigerant management services,
consisting primarily of recovery and reclamation of the refrigerants used in
commercial air conditioning and refrigeration systems, as well as
RefrigerantSide(TM) services, through which the Company performs decontamination
to remove moisture, oils and other contaminants in such systems. The Company
operates through its wholly owned subsidiaries Hudson Technologies Company and
Environmental Support Solutions, Inc. ("ESS").

The Company participates in an industry that is substantially regulated, changes
in which could affect operating results. Currently the Company purchases
unprocessed refrigerants from domestic suppliers. The Company's inability to
obtain refrigerants could cause delays in refrigerant processing, possible loss
of revenues, and resulting possible adverse affect on operating results.

Note 1-  Summary of Significant Accounting Policies

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial statements
and with the instructions of Regulation SB. Accordingly, they do not include all
the information and footnotes required by generally accepted accounting
principles for complete financial statements. The financial information included
in the quarterly report should be read in conjunction with the Company's audited
financial statements and related notes thereto for the year ended December 31,
1997.

In the opinion of management, all estimates and adjustments considered necessary
for a fair presentation have been included and all such adjustments were normal
and recurring.

Consolidation
The consolidated financial statements represent all companies of which Hudson
directly or indirectly has majority ownership or otherwise controls. Significant
inter-company accounts and transactions have been eliminated. The Company's
consolidated financial statements include the accounts of wholly owned
subsidiaries Hudson Holdings, Inc., Hudson Technologies Company, and ESS.

Fair value of financial instruments
The carrying values of financial instruments including trade accounts
receivable, and accounts payable approximate fair value at March 31, 1998 and
December 31, 1997, because of the relatively short maturity of these
instruments. The carrying value of short-and long-term debt approximates fair
value, based upon quoted market rates of similar debt issues.

Credit risk
Financial instruments, which potentially subject the Company to concentrations
of credit risk, consist principally of temporary cash investments and trade
accounts receivable. The Company maintains its temporary cash investments in
highly rated financial institutions. The Company's trade accounts receivables
are due from companies throughout the U.S. The Company reviews each customer's
credit history before extending credit.

The Company establishes an allowance for doubtful accounts based on factors
associated with the credit risk of specific accounts, historical trends, and
other information.

                   Hudson Technologies, Inc. and subsidiaries
                   Notes to Consolidated Financial Statements

Revenues and cost of sales
Revenues are recorded upon completion of service or product shipment or passage
of title to customers in accordance with contractual terms. Cost of sales is
recorded based on the cost of products shipped or services performed and related
direct operating costs of the Company's reclamation sites.

Cash and cash equivalents
Temporary investments with original maturities of ninety days or less are
included in cash and cash equivalents.

Inventories
Inventories, consisting primarily of reclaimed refrigerant products available
for sale, are stated at the lower of cost, on a first-in first-out basis, or
market.

Property, plant, and equipment
Property, plant, and equipment are stated at cost; including internally
manufactured equipment. Provisions for depreciation is recorded (for financial
reporting purposes) using the straight-line method over the useful lives of the
respective assets. Leasehold improvements are amortized on a straight-line basis
over the shorter of economic life or terms of the respective leases.

Due to the specialized nature of the Company's business, it is possible that the
Company's estimates of equipment useful life periods may change in the future.

Income taxes
The Company utilizes the asset and liability method for recording deferred
income taxes, which provides for the establishment of deferred tax asset or
liability accounts based on the difference between tax and financial reporting
bases of certain assets and liabilities.

Treasury stock
Common stock, acquired by the Company under a repurchase program authorized by
the Board of Directors is carried at acquisition cost (market price at
acquisition date).

Income (loss) per common and equivalent shares
Income (loss) per common share (Basic) is computed on the weighted average
number of shares, less treasury stock. If dilutive, common equivalent shares
(common shares assuming exercise of options and warrants) utilizing the treasury
stock method are considered in the presentation of dilutive earnings per share.

Recent accounting pronouncements
Statement of Financial Accounting Standard ("SFAS") No. 130, "Reporting
Comprehensive Income", established standards for reporting and display of
comprehensive income, its components and accumulated balances. Comprehensive
income is defined to include all changes in equity except those resulting from
investments by owners and distributions to owners. Among other disclosures, SFAS
No. 130 requires that all items that are required to be recognized under current
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements.

SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information", which supersedes SFAS No. 14, "Financial Reporting for Segments of
a Business Enterprise", establishes standards for the way that public
enterprises report information about operating segments in annual financial
statements and requires reporting of selected information about operating
segments in interim financial statements issued to the public. It also
establishes standards for disclosures regarding products and services,
geographic areas and


                                                                               6

major customers. SFAS No. 131 defines operating segments as components of an
enterprise about which separate financial information is available that is
evaluated regularly by Management in deciding how to allocate resources and in
assessing performance.

The Company adopted both SFAS Nos. 130 and 131, as of January 1, 1998.

Estimates and risks

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect reported amounts of certain assets and liabilities, the disclosure of
contingent assets and liabilities, and the results of operations during the
reporting period. Actual results could differ from these estimates.

The Company participates in an industry that is highly regulated, changes in
which could affect operating results. Currently, the Company purchases
unprocessed refrigerants from domestic suppliers and its customers. The
Company's inability to obtain refrigerants on commercially reasonable terms or a
decline in demand for refrigerant could cause delays in refrigerant processing,
possible loss of revenues, and could materially adversely affect operating
results.

Note 2 - Bank Credit Line

On April 28, 1998, the Company entered into a credit facility with CIT
Group/Credit Finance Group, Inc. ("CIT") which makes available borrowings to the
Company of up to $5,000,000 and increases to $6,500,000 in 1999. The facility
provides for a revolving line of credit and a six year term loan and expires in
April 2001. Advances under the revolving line of credit are limited to (i) 80%
of eligible trade accounts receivable and (ii) 50% of eligible inventory (which
inventory amount shall not exceed 200% of eligible trade accounts receivable or
$3,250,000). Advances, available to the Company, under the term loan (currently
approximately $1,000,000) are based on existing fixed asset valuations and
future advances under the term loan up to an additional $1,000,000 are based on
future capital expenditures. As of May 1, 1998 the Company had $1,250,000
outstanding under this facility. The facility bears interest at the prime rate
plus 1.5% and substantially all of the Company's assets are pledged as
collateral for obligations to CIT. This facility replaces the Company's previous
line of credit with MTB Bank ("MTB"). All obligations with MTB have been
satisfied subject to certain indemnification rights pursuant to an indemnity
agreement among CIT, MTB and the Company.

In connection with the loan agreements, the Company issued to CIT warrants to
purchase 30,000 shares of the Company's common stock at an exercise price equal
to 110% of the then fair market value of the stock which, on the date of
issuance was $4.33 per share and expires April 29, 2001. In addition, among
other things, the agreements restrict the Company's ability to declare or pay
any dividends on its capital stock.

                   Hudson Technologies, Inc. and subsidiaries
           Management's Discussion and Analysis of Financial Condition
                            and Results of Operations

The statements contained herein which are not historical facts are forward
looking statements that involve risks and uncertainties, including but not
limited to, changes in the markets for refrigerants (including unfavorable
market conditions adversely affecting the demand for, and the price of
refrigerants), regulatory and economic factors, increased competition, the
nature of supplier or customer arrangements which become available to the
Company in the future, adverse weather conditions, technological obsolescence
and potential environmental liability. The Company's actual results may differ
materially from the results discussed in any forward looking statement.

Results of Operations

Three months ended March 31, 1998 as compared to the three months ended March
31, 1997

Revenues for the three months ended March 31, 1998 were $6,705,000, a decrease
of $1,317,000 or 16% from the $8,022,000 reported during the comparable 1997
period. The decrease was attributable primarily to a lower volume of refrigerant
sales.

Cost of sales for the three months ended March 31, 1998 were $4,684,000, a
decrease of $2,150,000 or 31% from the $6,834,000 reported during the comparable
1997 period due mainly to a lower volume of refrigerant sales. As a percentage
of sales, cost of sales were 70% of revenues for the three month period ended
March 31, 1998, a decrease from the 85% reported for the comparable 1997 period.
The decrease in cost of sales as a percentage of revenues was primarily
attributable to a change in product mix with a higher volume of lower margin
refrigerant sales occurring during the 1997 period.

Operating expenses for the three months ended March 31, 1998 were $1,907,000, an
increase of $216,000 or 13% from the $1,691,000 reported during the comparable
1997 period. The increase was primarily attributable to an increase in payroll
and related expenses.

Net income for the three months ended March 31, 1998 was $55,000, an increase of
$713,000 from the net loss of $658,000 reported during the comparable 1997
period. The increase in net income was primarily attributable to higher gross
profits on refrigerant sales offset by an increase in operating expenses.

Liquidity and Capital Resources

At March 31, 1998, the Company had working capital of approximately $1,572,000.
A major component of current assets is inventory. The Company's ability to sell
its inventory and the prices at which it can be sold is subject to current
market conditions. The Company has historically financed its working capital
requirements through cash flows from operations, the issuance of debt and equity
securities, bank borrowings and loans from officers.

Net cash provided by operating activities was $69,000 for the three months ended
March 31, 1998 compared with net cash used by operating activities of $360,000
for the comparable 1997 period. Net cash provided by operating activities was
primarily attributable to the net income for the period.

Net cash used by investing activities was $109,000 for the three months ended
March 31, 1998 compared with net cash used by investing activities of $465,000
for the comparable 1997 period. The net cash usage consisted primarily of
equipment additions.

Net cash used by financing activities was $33,000 for the three months ended
March 31, 1998 compared with net cash provided by financing activities of
$880,000 for the comparable 1997 period. The net cash used by financing
activities in 1998 consisted of long-term debt repayment. Net cash provided by
financial activities in 1997 consisted of proceeds from the sale of stock offset
by repayment of debt.
                                                                               8

           Management's Discussion and Analysis of Financial Condition
                      and Results of Operations (continued)

At March 31, 1998, the Company had cash and equivalents of $553,000.

During 1996, the Company obtained financing from two lending institutions which
enabled it to rent an additional $1.7 million of equipment under terms of
operating leases. Hudson utilized these facilities to acquire automated aerosol
packaging equipment of approximately $1,000,000, ten refrigerant gas bulk-tank
storage units of approximately $400,000, and other industrial equipment of
$300,000.

On May 10, 1996, the Board of Directors authorized the Company to acquire, from
publicly traded markets, a maximum of 25,000 issued and outstanding shares of
its own Common Stock. As of December 31, 1996, the Company had repurchased
21,000 shares at an average price of $8.25 per share. No repurchases were made
subsequently.

On June 18, and September 30, 1996, the Company issued convertible debentures
with a combined face value of $5.3 million. These debentures were retired or
converted to common stock through January 1997.

In connection with its bankruptcy reorganization in June 1994, prior to its
acquisition by Hudson, Refrigerant Reclamation Corporation of America ("RRCA")
has obligations (as modified by a settlement during April 1996) totaling
$206,000 at March 31, 1998 payable in periodic payments to bankruptcy creditors
through July 2000.

On November 14, 1996, certain officers and stockholders of Hudson made unsecured
loans in the principal amount of $678,000 to the Company; repayable upon receipt
of proceeds from property mortgage discussed below or on subsequent demand. On
January 29, 1997, the Company repaid the officer loans together with accrued
interest outstanding.

During 1996, the Company mortgaged its property and building located in Ft.
Lauderdale, Florida with Turnberry Savings Bank, NA. The mortgage of $671,000 at
March 31, 1998 bears interest at a rate of 9.5% and is repayable over 20 years
through January 2017.

During January 1997, in connection with the execution of various agreements with
E.I. DuPont de Nemours ("DuPont'), the Company obtained additional equity funds
of $3,500,000 from an affiliate of DuPont. Proceeds were primarily utilized to
retire debt.

During January 1997, the Company entered into a commitment to purchase a 29,000
square foot facility on 5.15 acres in Congers, New York for about $1.4 million;
subject to approvals and ability to obtain financing. The Company is leasing the
facility in the interim period.

During May 1997, certain officers of Hudson made unsecured loans in the
aggregate principal amount of $585,000 to the Company. Such loans were due on
demand and bore interest from 8% to 8.88% per annum. On August 12, 1997, the
Company repaid the loans together with outstanding interest.

On April 28, 1998, the Company entered into a credit facility with CIT
Group/Credit Finance Group, Inc. ("CIT") which makes available borrowings to the
Company of up to $5,000,000 and increases to $6,500,000 in 1999. The facility
provides for a revolving line of credit and a six year term loan and expires in
April 2001. Advances under the revolving line of credit are limited to (i) 80%
of eligible trade accounts receivable and (ii) 50% of eligible inventory (which
inventory amount shall not exceed 200% of eligible trade accounts receivable or
$3,250,000). Advances, available to the Company, under the term loan (currently
approximately $1,000,000) are based on existing fixed asset valuations and
future advances under the term loan up to an additional $1,000,000 are based on
future capital expenditures. As of May 1, 1998 the Company had $1,250,000
outstanding under this facility. The facility bears interest at the prime rate
plus 1.5% and substantially all of the Company's assets are pledged as
collateral for obligations to CIT. This facility replaces the Company's previous
line of credit with MTB Bank ("MTB"). All obligations with MTB have

           Management's Discussion and Analysis of Financial Condition
                      and Results of Operations (continued)



been satisfied subject to certain indemnification rights pursuant to an
indemnity agreement among CIT, MTB and the Company.

In connection with the loan agreements, the Company issued to CIT warrants to
purchase 30,000 shares of the Company's common stock at an exercise price equal
to 110% of the then fair market value of the stock, which on the date of
issuance was $4.33 per share, and expires April 29, 2001. In addition, among
other things, the agreements restrict the Company's ability to declare or pay
any dividends on its capital stock.

The Company believes, based on current plans and assumptions, that its credit
facility will be sufficient to support its current operating requirements for
the foreseeable future. However, in the event that the Company's plans change or
its assumptions prove to be inaccurate or its credit facility is insufficient to
satisfy its cash requirements, the Company could be required to seek additional
financing. There can be no assurance that such additional financing will be
available.

Reliance on Suppliers

The Company's financial performance is in part dependent on its ability to
obtain sufficient quantities of domestic virgin and reclaimable refrigerants
from manufacturers, wholesalers, distributors, bulk gas brokers, and from other
sources; and on corresponding demand for reclaimed refrigerants. To the extent
that the Company is unable to obtain sufficient quantities of refrigerants in
the future, or resell reclaimed refrigerants at a profit, the Company's
financial condition and results of operations would be materially adversely
affected.

During January 1997, the Company entered into agreements with DuPont to market
DuPont's SUVA(TM) refrigerants. Under the agreement, 100% of virgin refrigerants
provided to specified market segment customers must be purchased from DuPont.


Seasonality and Fluctuations in Operating Results


The Company's operating results vary from period to period as a result of
weather conditions; requirements of potential customers; non-recurring
refrigerant sales and service; availability and price of refrigerant products
(virgin or reclaimable); changes in reclamation technology and regulations,
timing in introduction and/or retrofit or replacement of CFC-based refrigeration
equipment by domestic users of refrigerants, the rate of expansion of the
Company's operations; and by other factors. The Company's business has
historically been seasonal in nature with peak sales of refrigerants occurring
in the first half of each year. However, the second quarter of 1997 was
adversely impacted, in part, to the unseasonably cool weather. Delays in
securing adequate supplies of refrigerants at peak demand periods, lack of
refrigerant demand, increased expenses, and declining refrigerant prices have
resulted in significant losses. There can be no assurance that the foregoing
factors will not continue to result in a material adverse affect on the
Company's financial position and significant losses.


                                                                             10

                           PART II. OTHER INFORMATION
                   Hudson Technologies, Inc. and subsidiaries

Item 1.   Legal Proceedings

During June 1995, United Water of New York Inc. ("United") alleged that it
discovered that two of its wells within close proximity to the Company's
facility showed elevated levels of refrigerant contamination, specifically
trichlorofluoromethane (R-11). During June 1996, United notified the Company
that it was seeking indemnification by the Company for costs incurred to date as
well as costs expected to be incurred in connection with United taking remedial
action. During July 1996, United threatened to institute legal action in the
event that the Company declined to settle this matter.

During August 1996, the Company received a letter from the New York State
Department of Environmental Conservation ("DEC") which stated that, in the
opinion of DEC, the Company was the cause of the contamination of United's
wells. The DEC letter states that it is not aware of the extent of the
contamination or how the refrigerants entered the groundwater.

During December 1996, the Company and United entered into an interim settlement
agreement which provided for (a) reimbursement ($84,000) of United's operating
costs associated with certain wells through August 1996, (b) reimbursement,
subject to a dollar cap of $12,650 per month, of United's monthly operating
costs for certain wells from September 1996 through April 1997, and (c)
continued monitoring of R-11 refrigerant groundwater levels. Under the
agreement, United agreed not to commence legal action against the Company prior
to May 1, 1997. Neither party waived their rights as a result of the interim
agreement.

During August and September 1997, various proposals for possible further
remediation were discussed with the DEC and United in light of the reduction of
levels of R-11 in United's Wells. Since August 1997 the levels of R-11 have
remained nearly non-detectable and well under minimum contaminant levels
established by the State of New York. In January 1998, the Company agreed to
install a remediation system at the Company's facility to remove any remaining
R-11 levels in the groundwater under and around the Company's facility.

During December 1997, United Water alleged that it discovered levels of
Dichlorodifluoromethane (R-12) in two of its wells within close proximity to the
Company's facility, and has alleged that the Company is the source. Sampling by
the Company of various monitoring wells installed around the Company's
facilities have been taken on a monthly basis since August 1996 and have failed
to detect any levels of R-12 in the groundwater in and around the Company's
facility.

There can be no assurance that United will not commence legal action seeking
substantial damages and/or other relief, or that any legal action or settlement
will be resolved in a manner favorable to the Company, or that the ultimate
outcome of any legal action or settlement will not have a material adverse
effect on the Company's financial condition and results of operations.

In June 1997, an action was commenced against the Company in the 19th Judicial
District Court, Parish East Baton Rouge, State of Louisiana, by a former
salesperson and her spouse, who was terminated by the Company in June 1996,
alleging that the Company wrongfully terminated the employee, and is seeking
unspecified damages. This action was settled in April 1998.

During March and April, 1998, six (6) complaints, each alleging violations of
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, were filed by a
total of eight shareholders, on behalf of themselves and all others similarly
situated, against the Company and certain of its officers and directors in the
United States District Court for the Southern District of New York. Each of the
complaints alleges that the defendants, among other things, misrepresented
material information about the Company's financial results and prospects, and
its customer relationships. The complaints in five of these actions seek relief
on behalf of

11
<PAGE>

persons purchasing common stock between August 8, 1995 and August 15, 1997, and
the complaint in the sixth action seeks relief on behalf of persons purchasing
common stock between March 31, 1997 and August 15, 1997. The Company maintains
that the allegations of wrongdoing alleged in the complaints are without merit.
The Company intends to vigorously defend the claims brought against it and has
retained the law firm of Davis, Polk and Wardwell for that defense.

There can be no assurance that any of these actions, or the settlement thereof,
will be resolved in a manner favorable to the Company, or that the ultimate
outcome of any legal action or settlement will not have a material adverse
effect on the Company's financial condition and results of operations.

Hudson Technologies and its subsidiaries are subject to various claims and/or
lawsuits from both private and governmental parties arising from the ordinary
course of business; none of which are material.

Item 2. Changes in Securities and Use of Proceeds

During the three months ended March 31, 1998, the Company granted options to
purchase 4,300 shares of common stock to certain employees pursuant to its 1997
Stock Option Plan. The Company relied on Section 4(2) under the Securities Act
of 1933 as transactions by an issuer not involving a public offering.

Exhibit 10


                           LOAN AND SECURITY AGREEMENT


         This Agreement is between the undersigned Borrower and the undersigned
Lender concerning loans and other credit accommodations to be made by Lender to
Borrower.

SECTION 1.        PARTIES

         1.1 The "Affiliated Borrower" is ENVIRONMENTAL SUPPORT SOLUTIONS, INC.,
and its successors and assigns.

         1.2 The "Borrower" is the person, firm, corporation or other entity,
identified as the Borrower in Section 10.6(c) and its successors and assigns. If
more than one Borrower is specified in Section 10.6(c), all references to
Borrower shall mean each of them, jointly and severally, individually and
collectively, and the successors and assigns of each.

         1.3 The "Lender" is The CIT Group/Credit Finance, Inc. and its
successors and assigns.

SECTION 2.        LOANS AND OTHER CREDIT ACCOMMODATIONS

         2.1 Revolving Loans. Lender shall, subject to the terms and conditions
contained herein, make revolving loans to Borrower ("Revolving Loans") in
amounts requested by Borrower from time to time, but not in excess of the Net
Availability existing immediately prior to the making of the requested loan and
provided the requested loan would not cause the outstanding Obligations
hereunder plus the then outstanding "Obligations" under and as said quoted term
is defined in the Affiliate Loan Agreements (as defined in Section 10.8 below),
to exceed, in the aggregate, the Maximum Credit.

                  (a) The "Maximum Credit" is set forth in Section 10.1(a)
hereof.

                  (b) The "Gross Availability" shall be calculated at any time
as (i) the product obtained by multiplying the outstanding amount of Eligible
Accounts by the Eligible Accounts Percentage set forth in Section 10.1(b),
("Accounts Availability"),

                           plus: (ii) the product(s) obtained by multiplying the
                           applicable Eligible Inventory Percentage(s), if any,
                           set forth in Section 10.1(b) by the values (as
                           determined by Lender based on the lower of cost or
                           market and, in the case of Eligible L/C Inventory (as
                           defined below), net of all duty, freight, taxes,
                           costs, insurance and other charges and expenses which
                           may pertain to such Eligible L/C Inventory)) of
                           Eligible Inventory, but the amount so added shall not
                           exceed any sublimits set forth in Section 10.1(c)
                           ("Inventory Availability"),

                           minus (iii) Reserves, if any.

                  (c) The "Net Availability" shall be calculated at any time as
an amount equal to the Gross Availability minus the aggregate amount of all
then-outstanding Obligations to Lender other than the then outstanding principal
balance of the Term Loan and the Cap/Ex Loans, if any.

                                                                              14

                  (d) "Eligible Accounts" are accounts created by Borrower in
the ordinary course of its business which are and remain acceptable to Lender
for lending purposes. General criteria for Eligible Accounts are set forth below
but may be revised from time to time by Lender, in its sole judgment, on fifteen
(15) days' prior written notice to Borrower. Lender shall, in general, deem
accounts to be Eligible Accounts if: (1) such accounts arise from bona fide
completed transactions and have not remained unpaid for more than the earlier of
(A) the number of days after the invoice date set forth in Section 10.1(d)(i);
and (B) the number of days after the due date of such invoice set forth in
Section 10.1(d)(ii); (2) the amounts of the accounts reported to Lender are
absolutely owing to Borrower and do not arise from sales on consignment,
guaranteed sale or other terms under which payment by the account debtors may be
conditional or contingent; (3) (A) the account debtor's chief executive office
or principal place of business is located in the United States or Canada (other
than the Province of Quebec) or (B) the account debtor's chief executive office

otherwise not located in the United States or Canada ("Foreign Accounts") and
such Foreign Accounts are (x) insured by a credit insurance policy in form,
substance and amount satisfactory to Lender, which policy, together with the
proceeds thereof, shall be duly assigned to Lender, or (y) Borrower and/or such
account debtor has delivered an irrevocable letter of credit issued or confirmed
by a bank satisfactory to Lender, sufficient to cover such Account, in form and
substance satisfactory to Lender, and the original of such letter of credit has
been delivered to Lender or Lender's agent and the issuer thereof notified of
the assignment of the proceeds of such letter of credit to Lender; (4) such
accounts do not arise from progress billings retainages or bill and hold sales;
(5) there are no contra relationships, setoffs, counterclaims or disputes
existing with respect thereto and there are no other facts existing or
threatened which would impair or delay the collectibility of all or any portion
thereof; (6) the goods giving rise thereto were not at the time of the sale
subject to any liens except those permitted in this Agreement; (7) such accounts
are not accounts with respect to which the account debtor or any officer or
employee thereof is an officer, employee or agent of or is affiliated with
Borrower, directly or indirectly, whether by virtue of family membership,
ownership, control, management or otherwise; (8) such accounts are not accounts
with respect to which the account debtor is the United States or any State or
political subdivision thereof or any department, agency or instrumentality of
the United States, any State or political subdivision, unless there has been
compliance with the Assignment of Claims Act or any similar State or local law,
if applicable; (9) Borrower has delivered to Lender or Lender's representative
such documents as Lender may have reasonably requested pursuant to Section 5.8
hereof in connection with such accounts and Lender shall have received a
verification of such account, satisfactory to it, if sent to the account debtor

are no facts existing or threatened which might result in any adverse change in
the account debtor's financial condition; (11) such accounts owed by a single
account debtor or its affiliates do not represent more than twenty percent (20%)
of all otherwise Eligible Accounts except that notwithstanding anything to the
contrary contained herein, in the case of E.I. DuPont De Nemours and Company
such accounts do not represent more than the greater of (A) the lesser of (x)
sixty percent (60%) of all otherwise Eligible Accounts and (y) $1,000,000 and
(B) thirty percent (30%) of all otherwise Eligible Accounts (accounts excluded
from Eligible Accounts solely by reason of this subsection (11) shall
nevertheless be considered Eligible Accounts to the extent of the amount of such
accounts which does not exceed the applicable percentage stated above, as
applicable, of all otherwise Eligible Accounts); (12) such accounts are not owed
by an account debtor who is or whose affiliates are past due upon other accounts
owed to Borrower comprising more than fifty percent (50%) of the accounts of
such account debtor or its affiliates owed to Borrower; (13) such accounts are

Accounts solely by reason of this subsection (13) shall nevertheless be
considered Eligible Accounts to the extent the amount of such accounts does not
exceed such customer credit limit); and (14) such accounts are owed by account
debtors deemed creditworthy at all times by Lender.

                  (e) "Eligible Inventory" is (i) inventory consisting of
finished goods owned by Borrower which is and remains acceptable to Lender for
lending purposes and is located at one of the addresses set forth in Section
10.6(e), or at such other addresses as Borrower may from time to time notify
Lender in accordance with Section 6.4 below; and (ii) Eligible L/C Inventory (as
defined below). For the purposes hereof:

                           (1) "Eligible L/C Inventory" shall mean all finished
goods inventory owned, or which are being manufactured for and will be owned, by
Borrower and covered by an Accommodation (as defined below), which is in the
form of a documentary letter of credit and which finished goods are in transit
to one of the Borrower's addresses set forth in Section 10.6(e) and which
finished goods (A) as of the date such inventory are owned by Borrower (x) are
fully insured, (y) are subject to a first priority security interest in and lien
upon such goods in favor of Lender (except for any possessory lien upon such
goods in the possession of a freight carrier or shipping company securing only
the freight charges for the transportation of such goods to Borrower) and (z)
all documents, notices, instruments, statements and bills of lading relating
thereto, if any, which Lender may reasonably deem necessary or desirable to
evidence ownership by Borrower and/or to give effect to and protect the liens,
security interests and other rights of Lender in connection therewith, are
delivered to Lender; and (B) is and remains acceptable to Lender for lending
purposes; and

                  (f) (i) Lender shall have a continuing right to deduct
reserves in determining the Gross Availability ("Reserves"), and to increase and
decrease such Reserves from time to time, if and to the extent that, in Lender's
sole judgment, such Reserves are necessary to protect Lender against any state
of facts which does, or would, with notice or passage of time or both,
constitute an Event of Default or have an adverse effect on any Collateral.
Lender may, at its option, implement Reserves by designating as ineligible a
sufficient amount of accounts or inventory which would otherwise be Eligible
Accounts or Eligible Inventory so as to reduce Gross Availability by the amount
of the intended Reserve. The amount of any reduction in the lending formulas by
Lender shall have a reasonable relationship to the matter which is the basis for
such a reduction.

                           (ii) Without in any way limiting the foregoing,
Borrower hereby acknowledges and consents to the establishment, as of the date
hereof, of a reserve against Borrower's Gross Availability in the amount of
$500,000 (the "Contingent Liability Reserve"). The Contingent Liability Reserve
shall be released, if and only if, the Borrower's cumulative net income for 1998
(exclusive of any gains from extraordinary items, discontinued operations and
changes in accounting principles) as reflected in Hudson Technologies, Inc.'s
Form 10-Q Report or Form 10-K Report, as applicable, for any period indicated
below exceeds the respective amount indicated below for such period:

Period                                         Required Cumulative Net Income
- ------                                         ------------------------------
Six (6) months ending June 30, 1998                     $562,000
Nine (9) months ending September 30, 1998               $864,000
Twelve (12) months ending December 31, 1998             $628,000

provided that, there are then no outstanding factored accounts receivable
("Outstanding Factored Accounts") under that certain Letter of Indemnity dated
as of the date hereof by and between Lender and MTB Bank (the "MTB Indemnity
Letter"). If there are then any remaining Outstanding Factored Accounts, then
notwithstanding the foregoing, the Contingent Liability Reserve shall remain in
an amount equal to the lesser of: (A) the amount of such remaining Outstanding
Factored Accounts and (B) $500,000. The determination of any reduction in the
Outstanding Factored Accounts under the MTB Indemnity Letter shall be made
monthly by Lender based upon the written statements of MTB Bank delivered to
Lender.

                                                                              16
<PAGE>

                  (g) Subject to the terms and conditions hereof, including but
not limited to the existence of sufficient Gross Availability and Net
Availability, Borrower and Affiliated Borrower, jointly and severally, agree to
borrow sufficient amounts from time to time so that the outstanding Revolving
Loans hereunder plus the outstanding "Revolving Loans" under, and as said quoted
term defined in, the Affiliate Loan Agreements, shall at all times equal or
exceed the principal amount set forth in Section 10.1(e) as the Minimum
Borrowing; provided, that if Borrower and Affiliated Borrower fail to do so,
interest shall nevertheless accrue on the Obligations as if Borrower and
Affiliated Borrower had borrowed such amounts as would have been sufficient to
maintain the outstanding Revolving Loans hereunder and under the Affiliate Loan
Agreements at an amount equal to the Minimum Borrowing (and, on a monthly basis,
Lender shall have the right to charge Borrower's loan account for such
additional interest), and provided further that such accrual shall not impose
upon Lender any obligation to make loans to Borrower or Affiliated Borrower to
increase the outstanding Revolving Loans hereunder or the Affiliate Loan
Agreements to such Minimum Borrowing in the event that sufficient Net
Availability does not then exist.

         2.2      Term Loan and Cap/Ex Loans.

                  (a) Any term loan and the terms of such loan, made by Lender
to Borrower are set forth in Section 10.2 ("Term Loan").

                  (b) (i) In addition to all other loans, advances and other
financial accommodations to be made by Lender pursuant to this Agreement and
subject to the terms and conditions set forth herein, Lender agrees to make
additional loans to Borrower, upon Borrower's written request, for the purpose
of purchasing or acquiring Eligible Equipment (as defined below) or financing
capital expenditures (collectively, the "Cap/Ex Loans"). Each Cap/Ex Loan shall
be in an amount not to exceed eighty (80%) percent of the Equipment Purchase
Price (as defined below) in respect of the Eligible Equipment to be financed
thereby, provided, however, that after giving effect to a Cap/Ex Loan requested
by Borrower, the sum of (1) such requested Cap/Ex Loan and (2) the aggregate
original principal amount of all prior Cap/Ex Loans is not greater than
$1,000,000. Borrower shall provide Lender with not less than ten (10) days prior
written notice of each requested Cap/Ex Loan. Each Cap/Ex Loan shall bear
interest from the date such Cap/Ex Loan is made at the applicable rate set forth
in Section 10.4(a) and such interest shall be payable in accordance with Section
3.1.

                           (ii) The aggregate principal amount of each Cap/Ex
Loan shall be repaid in seventy-two (72) consecutive monthly principal
installments (or earlier as herein provided) commencing on the first day of the
first calendar month next following the date of each such Cap/Ex Loan and
monthly thereafter on the first day of each successive month until paid, of
which the first seventy-one (71) principal installments shall each be in a
minimum amount equal to the quotient of the principal amount of such Cap/Ex Loan
divided by seventy-two (72); and the last and seventy-second (72nd) principal
installment shall be in the amount of the entire unpaid balance of such Cap/Ex
Loan.

                           (iii) In addition to all other rights and remedies
under this Agreement, the Cap/Ex Loans, together with all accrued and unpaid
interest thereon and the early termination fee in respect thereof, shall, at
Lender's option, be immediately due and payable if this Agreement shall be
terminated or not renewed for any reason whatsoever, or upon the occurrence of
any Event of Default hereunder.



17
<PAGE>

                           (iv) Each Cap/Ex Loan shall be in an amount of not
less than $100,000.

                           (v) The making of any Cap/Ex Loans is further subject
to the satisfaction of each of the following conditions precedent in a manner
satisfactory to Lender:

                                    (1) no Event of Default shall have occurred
and be continuing and no event shall have occurred or condition be existing and

shall execute and perform additional agreements relating to the Accommodations
in form and substance acceptable to Lender and the issuer of any Accommodations,
all of which shall supplement the rights and remedies granted herein. Any
payments made by Lender or any affiliate of Lender in connection with the
Accommodations shall constitute additional Revolving Loans to Borrower.

                  (b) In addition to the fees and costs of any issuer in
connection with issuing or administering Accommodations, Borrower shall pay
monthly to Lender, on the first day of each month, a charge on open

"Accommodation Charges").

                  (c) No Accommodation will be issued unless the full amount of
the Accommodation requested, plus fees and costs for issuance, is less than the
Net Availability existing immediately prior to the issuance of the requested
Accommodation, or if the requested Accommodation would cause the outstanding
Obligations to exceed the Maximum Credit, or cause the open amount of
Accommodations hereunder, together with the open amount of "Accommodations"
under, and as said quoted term is defined in, the Affiliate Loan Agreements to
exceed, at any time, the Accommodation sublimit set forth in Section 10.3(b).

incurred in connection with any Accommodation shall be included in the term
"Obligations", as defined herein, and shall include, without limitation, (i) all
amounts due or which may become due under any Accommodation; (ii) all amounts
charged or chargeable to Borrower or to Lender on account of Borrower, the
Collateral, the Obligations or the Accommodations by any bank, other financial
institution or correspondent bank which opens, issues or is involved with such
Accommodations; (iii) Lender's Accommodation Charges and all fees, costs and
other charges of any issuer of any Accommodation; and (iv) all duties, freight,
taxes, costs, insurance and all such other charges and expenses which may
pertain directly or indirectly to any Obligations or Accommodations or to the
goods or documents relating thereto, unless and to the extent paid directly by
Borrower.

                  (e) Borrower unconditionally agrees to indemnify and hold
Lender harmless from any and all loss, claim or liability (including reasonable
attorneys' fees) arising from any transactions or occurrences relating to any
Accommodation established or opened for Borrower's account, the Collateral
relating thereto and any drafts or acceptances thereunder, including any such
loss or claim due to any action taken by an issuer of any Accommodation.
Borrower further agrees to indemnify and hold Lender harmless for any errors or
omissions in connection with the Accommodations, whether caused by Lender, by
the issuer of any Accommodation or otherwise. Borrower's unconditional
obligation to indemnify and hold Lender harmless under this provision shall not
be modified or diminished for any reason or in any manner whatsoever, except for
Lender's willful misconduct or gross negligence. Borrower agrees that any
charges made to Lender by any issuer of any Accommodation shall be conclusive on
Borrower and may be charged to Borrower's account.

                  (f) Lender shall not be responsible for: the conformity of any
goods to the documents presented; the validity or genuineness of any documents;
delay, default, or fraud by the Borrower or shipper and/or anyone else in
connection with the Accommodations or any underlying transaction.

<PAGE>

                  (g) Borrower agrees that any action taken by Lender, if taken
in good faith, or any action taken by an issuer of any Accommodation, under or
in connection with any Accommodation, shall be binding on Borrower and shall not
create any resulting liability to Lender. In furtherance thereof, Lender shall
have the full right and authority to clear and resolve any questions of
non-compliance of documents; to give any instructions as to acceptance or
rejection of any documents or goods; to execute for Borrower's account any and
all applications for steamship or airway guarantees, indemnities or delivery
orders; to grant any extensions of the maturity of, time of payment for, or time
of presentation of, any drafts, acceptances, or documents; and to agree to any
amendments, renewals, extensions, modifications, changes or cancellations of any
of the terms or conditions of any of the applications or Accommodations. All of
the foregoing actions may be taken in Lender's sole name, and the issuer thereof
shall be entitled to comply with and honor any and all such documents or
instruments executed by or received solely from Lender, all without any notice
to or any consent from Borrower. None of the foregoing actions described in this
subsection (g) may be taken by Borrower without Lender's express written
consent.

Borrower or the exercise of any other right or remedy by Lender), and all such
interest shall be payable on demand. Interest shall in no month be less than the
Interest Rate multiplied by the Minimum Borrowing. In no event shall charges
constituting interest exceed the rate permitted under any applicable law or
regulation, and if any provision of this Agreement is in contravention of any
such law or regulation, such provision shall be deemed amended to conform
thereto.

                  (b) The "Prime Rate" is the rate of interest publicly

Borrower, shall pay Lender at closing a Closing Fee in the amount set forth in

<PAGE>

         3.5 Unused Line Fee. Borrower, jointly and severally with Affiliated
Borrower, shall pay Lender monthly, on the first day of each month, in arrears,
an Unused Line Fee for each month during the initial and each renewal Term at
the rate per annum set forth in Section 10.4(f), calculated upon the amount, if
any, by which the Maximum Credit exceeds the average aggregate outstanding daily
principal balance during the preceding month of all Revolving Loans,
Accommodations, Cap/Ex Loans and any Term Loan hereunder and all Revolving Loans
under the Affiliate Loan Agreements.

         3.6 Charges to Loan Account. At Lender's option, all payments of
principal, interest, fees, costs, expenses and other charges provided for in

Lender based on a per annum rate shall be calculated on the basis of actual days
elapsed over a 360-day year.

in full of all Obligations, Borrower hereby grants to Lender a continuing

         5.1 Collections. Borrower shall, at Borrower's expense and in the
manner requested by Lender from time to time, direct that remittances and all
other proceeds of accounts and other Collateral be sent to a lock box designated
by and/or maintained in the name of Lender, and deposited into a bank account
now or hereafter selected by Lender and maintained in the name of Lender under
arrangements with the depository bank under which all funds deposited to such
bank account are required to be transferred solely to Lender. Borrower shall
bear all risk of loss of any funds deposited into such account. In connection
therewith, Borrower shall execute such lock box and bank account agreements as
Lender shall specify. Any collections or other proceeds received by Borrower
shall be held in trust for Lender and immediately remitted to Lender in kind.

         5.2 Payments. All Obligations shall be payable at Lender's office set
forth below or at Lender's bank designated in Section 10.6(a) or at such other
bank or place as Lender may expressly designate from time to time for purposes
of this Section. Lender shall apply all proceeds of accounts or other Collateral
received by Lender and all other payments in respect of the Obligations to the
Revolving Loans or to any other Obligations then due, in whatever order or
manner Lender shall determine. For purposes of determining Gross Availability
and Net Availability and for the calculation of the Minimum Borrowing,
remittances and other payments with respect to the Collateral and Obligations
will be treated as credited to the loan account of Borrower maintained by Lender
and Collateral balances to which they relate, upon the date of Lender's receipt
of advice from Lender's bank that such remittances or other payments have been
credited to Lender's account or in the case of remittances or other payments
received directly in kind by Lender, upon the date of Lender's deposit thereof
at Lender's bank, subject to final payment and collection. In computing interest
charges, the loan account of Borrower maintained by Lender will be credited with
remittances and other payments the number of days set forth in Section 10.4(b)
after the day Lender has received advice of receipt of remittances in Lender's
account at Lender's Bank. For purposes of this Agreement, "Business Day" shall
mean any day other than a Saturday, Sunday or any other day on which banks
located in states where Lender has its offices, are authorized to close.


                                                                              22
<PAGE>

         5.3 Loan Account Statements. Lender shall render to Borrower monthly a
loan account statement. Each statement shall be considered correct and binding
upon Borrower as an account stated, except to the extent that Lender receives,
within sixty (60) days after the mailing of such statement, written notice from
Borrower of any specific exceptions by Borrower to that statement.

         5.4 Direct Collections. Lender may, at any time, whether or not an
Event of Default has occurred, without notice to or assent of Borrower, (a)
notify any account debtor that the accounts and other Collateral which includes
a monetary obligation have been assigned to Lender by Borrower and that payment
thereof is to be made to the order of and directly to Lender, (b) send, or cause
to be sent by its designee, requests (which may identify the sender by a
pseudonym) for verification of accounts and other Collateral directly to any
account debtor or any other obligor or any bailee with respect thereto, and (c)
demand, collect or enforce payment of any accounts or such other Collateral, but
without any duty to do so, and Lender shall not be liable for any failure to
collect or enforce payment thereof; provided that, so long as no Event of
Default has occurred, Lender agrees to use its best efforts to provide Borrower
with notice of any demand, collection or enforcement of payment by Lender
pursuant to this Section 5.4(c). At Lender's request, all invoices and
statements sent to any account debtor, other obligor or bailee, shall state that
the accounts and such other Collateral have been assigned to Lender and are
payable directly and only to Lender.

         5.5 Attorney-in-Fact. Borrower hereby appoints Lender and any designee
of Lender as Borrower's attorney-in-fact and authorizes Lender or such designee,
at Borrower's sole expense, to exercise at any times in Lender's or such
designee's discretion all or any of the following powers, which powers of
attorney, being coupled with an interest, shall be irrevocable until all
Obligations have been paid in full: (a) receive, take, endorse, assign, deliver,
accept and deposit, in the name of Lender or Borrower, any and all cash, checks,
commercial paper, drafts, remittances and other instruments and documents
relating to the Collateral or the proceeds thereof, (b) transmit to account
debtors, other obligors or any bailees notice of the interest of Lender in the
Collateral or request from account debtors or such other obligors or bailees at
any time, in the name of Borrower or Lender or any designee of Lender,
information concerning the Collateral and any amounts owing with respect
thereto, (c) notify account debtors or other obligors to make payment directly
to Lender, or notify bailees as to the disposition of Collateral, (d) take or
bring, in the name of Lender or Borrower, all steps, actions, suits or
proceedings deemed by Lender necessary or desirable to effect collection of or
other realization upon the accounts and other Collateral, (e) after an Event of
Default, change the address for delivery of mail to Borrower and to receive and
open mail addressed to Borrower (Lender agrees to use its best efforts to
forward to Borrower any mail addressed to Borrower actually received by Lender
pursuant to this Section 5.5(e) which does not relate to the Obligations, the
Collateral, any transactions arising hereunder or related hereto), (f) after an
Event of Default, extend the time of payment of, compromise or settle for cash,
credit, return of merchandise, and upon any terms or conditions, any and all
accounts or other Collateral which includes a monetary obligation and discharge
or release the account debtor or other obligor, without affecting any of the
Obligations, and (g) execute in the name of Borrower and file against Borrower
in favor of Lender financing statements or amendments with respect to the
Collateral.

         5.6 Liability. Borrower hereby releases and exculpates Lender, its
officers, employees and designees, from any liability arising from any acts
under this Agreement or in furtherance thereof, whether as attorney-in-fact or
otherwise, whether of omission or commission, and whether based upon any error
of judgment or mistake of law or fact, except for willful misconduct or gross
negligence. In no event will Lender have any liability to Borrower for lost
profits or other special or consequential damages.

23
<PAGE>

         5.7 Administration of Accounts. After written notice by Lender to
Borrower and automatically, without notice, after an Event of Default, Borrower
shall not, without the prior written consent of Lender in each instance, (a)
grant any extension of time of payment of any of the accounts or any other
Collateral which includes a monetary obligation, (b) compromise or settle any of
the accounts or any such other Collateral for less than the full amount thereof,
(c) release in whole or in part any account debtor or other person liable for
the payment of any of the accounts or any such other Collateral, or (d) grant
any credits, discounts, allowances, deductions, return authorizations or the
like with respect to any of the accounts or any such other Collateral.

         5.8 Documents. At such times as Lender may request and in the manner
specified by Lender, Borrower shall deliver to Lender or Lender's
representative, as Lender shall designate, copies or original invoices,
agreements, proofs of rendition of services and delivery of goods and other
documents evidencing or relating to the transactions which gave rise to accounts
or other Collateral, together with customer statements, schedules describing the
accounts or other Collateral and/or statements of account and confirmatory
assignments to Lender of the accounts or other Collateral, in form and substance
satisfactory to Lender and duly executed by Borrower. Without limiting the
provisions of Section 5.7, Borrower's granting of credits, discounts,
allowances, deductions, return authorizations or the like will be promptly
reported to Lender in writing. In no event shall any such schedule or
confirmatory assignment (or the absence thereof or omission of any of the
accounts or other Collateral therefrom) limit or in any way be construed as a
waiver, limitation or modification of the security interests or rights of Lender
or the warranties, representations and covenants of Borrower under this
Agreement. Any documents, schedules, invoices or other paper delivered to Lender
by Borrower may be destroyed or otherwise disposed of by Lender six (6) months
after receipt by Lender, unless Borrower requests their return in writing in
advance and makes prior arrangements for their return at Borrower's expense.

         5.9 Access. From time to time as requested by Lender, at the sole
expense of Borrower, Lender or its designee shall have access, prior to an Event
of Default during reasonable business hours and on or after an Event of Default
at any time, to all of the premises where Collateral is located for the purposes
of inspecting the Collateral, and all Borrower's books and records, and Borrower
shall permit Lender or its designee to make such copies of such books and
records or extracts therefrom as Lender may request. Without expense to Lender,
Lender may use such of Borrower's personnel, equipment, including computer
equipment, programs, printed output and computer readable media, supplies and
premises for the collection of accounts and realization on other Collateral as
Lender, in its sole discretion, deems appropriate. Borrower hereby irrevocably
authorizes all accountants and third parties to disclose and deliver to Lender
at Borrower's expense all financial information, books and records, work papers,
management reports and other information in their possession regarding Borrower.

         5.10 Environmental Audits. From time to time, as reasonably requested
by Lender, at the sole expense of Borrower, Borrower shall provide Lender, or
its designee, complete access to all of Borrower's facilities for the purpose of
conducting an environmental audit of such facilities as Lender or its designees
may deem necessary. Borrower agrees to cooperate with Lender with respect to any
environmental audit conducted by Lender or its designee pursuant to this Section
5.10.

         5.11 Credit Balance. Borrower agrees that Lender shall hold as security
for the Obligations the amount of not less than $495,000 delivered by MTB Bank
to Lender (the "Indemnification Balance") pursuant to the MTB Indemnity Letter.
The Indemnification Balance shall constitute a part of the Collateral. So long
as no Event of Default then exists and is continuing, Lender shall on a monthly
basis release to Borrower a portion of the beginning Indemnification Balance
with such portion calculated as the beginning Indemnification Balance multiplied
by a fraction with the numerator of such fraction being the dollar amount of
factored accounts of Borrower which MTB Bank has reported to Lender in MTB
Bank's written monthly statements delivered to Lender as collected during the
immediately preceding month and the denominator being the amount of $1,726,000.


                                                                              24

books and records in accordance with generally accepted accounting principles,
consistently applied. Borrower shall, at its expense, deliver to Lender (a) on

Borrower's fiscal year. All of the foregoing shall be in such form and together
with such information with respect to the business of Borrower or any guarantor,
as Lender may in each case request.

         6.2 Trade Names. Borrower may from time to time render invoices to
account debtors under its trade names set forth in Section 10.6(g) after Lender
has received prior written notice from Borrower of the use of such trade names
and as to which, Borrower agrees that: (a) each trade name does not refer to
another corporation or other legal entity, (b) all accounts and proceeds thereof
(including any returned merchandise) invoiced under any such trade names are
owned exclusively by Borrower and are subject to the security interest of Lender
and the other terms of this Agreement, and (c) all schedules of accounts and
confirmatory assignments including any sales made or services rendered using the
trade name shall show Borrower's name as assignor and Lender is authorized to

Borrower representing payment with respect to such sales or services.

         6.3 Losses. Borrower shall promptly notify Lender in writing of any

otherwise.

and its chief executive office are and shall be maintained only at the address
set forth in Section 10.6(d). Borrower's only other places of business and the
only other locations of Collateral, if any, are and shall be the addresses set
forth in Section 10.6(e) and Section 10.6(f) hereof, except Borrower may change

written notice to Lender. Prior to any change in location or opening of any new
place of business, Borrower shall execute and deliver or cause to be executed
and delivered to Lender such financing statements, financing documents and
security and other agreements as Lender may reasonably require, including,
without limitation, those described in Section 6.14.

         6.5 Title. Borrower has and at all times will continue to have good and
marketable title to all of the Collateral, free and clear of all liens, security
interests, claims or encumbrances of any kind except in favor of Lender and
except, if any, those set forth on Schedule A hereto.

         6.6 Disposition of Assets. Borrower shall not directly or indirectly
without Lender's prior written consent: (a) sell, lease, transfer, assign,
abandon or otherwise dispose of any part of the Collateral or any material
portion of its other assets (other than sales of inventory to buyers in the
ordinary course of business) or (b) consolidate with or merge with or into any
other entity, or permit any other entity to consolidate with or merge with or
into Borrower or (c) form or acquire any interest in any firm, corporation or
other entity.

         6.7 Insurance. Borrower shall at all times maintain, with financially
sound and reputable insurers, insurance (including, without limitation, at the
option of Lender, earthquake and flood insurance) with respect to the Collateral
and other assets. All such insurance policies shall be in such form, substance,
amounts and coverage as may be satisfactory to Lender and shall provide for
thirty (30) days' prior written notice to Lender of cancellation or reduction of
coverage. Borrower hereby irrevocably appoints Lender and any designee of Lender
as attorney-in-fact for Borrower to obtain at Borrower's expense, any such
insurance should Borrower fail to do so and, after an Event of Default, to
adjust or settle any claim or other matter under or arising pursuant to such
insurance or to amend or cancel such insurance. Borrower shall deliver to Lender
evidence of such insurance and a lender's loss payable endorsement satisfactory
to Lender as to all existing and future insurance policies with respect to the
Collateral. Borrower shall deliver to Lender, in kind, all instruments
representing proceeds of insurance received by Borrower. Lender may apply any
insurance proceeds received at any time to the cost of repairs to or replacement
of any portion of the Collateral and/or, at Lender's option, to payment of or as
security for any of the Obligations in any order or manner as Lender determines.

         6.8 Compliance With Laws. Borrower is and at all times will continue to
be in compliance with the requirements of all material laws, rules, regulations
and orders of any governmental authority relating to its business (including
laws, rules, regulations and orders relating to taxes, payment and withholding
of payroll taxes, employer and employee contributions and similar items,
securities, employee retirement and welfare benefits, employee health and
safety, or environmental matters) and all material agreements or other
instruments binding on Borrower or its property. All of Borrower's inventory
shall be produced in accordance with the requirements of the Federal Fair Labor
Standards Act of 1938, as amended and all rules, regulations and orders related
thereto. Borrower shall pay and discharge all taxes, assessments and
governmental charges against Borrower or any Collateral prior to the date on
which penalties are imposed or liens attach with respect thereto, unless the
same are being contested in good faith and, at Lender's option, Reserves are
established for the amount contested and penalties which may accrue thereon.

         6.9 Accounts. With respect to each account deemed an Eligible Account,
except as reported in writing to Lender, Borrower has no knowledge that any of
the criteria for eligibility are not or are no longer satisfied. As to each
account, except as disclosed in writing to Lender at the time such account
arises (a) each is valid and legally enforceable and represents an undisputed
bona fide indebtedness incurred by the account debtor for the sum reported to
Lender, (b) each arises from an absolute and unconditional sale of goods,
without any right of return or consignment, or from a completed rendition of
services, (c) each is not, at the time such account arises, subject to any
defense, offset, dispute, contra relationship, counterclaim, or any given or
claimed credit, allowance or discount, and (d) all statements made and all
unpaid balances and other information appearing in the invoices, agreements,
proofs of rendition of services and delivery of goods and other documentation
relating to the accounts, and all confirmatory assignments, schedules,
statements of account and books and records with respect thereto, are true and
correct and in all respects what they purport to be.

                                                                              26

advances to any officer, director, employee, shareholder or affiliate of

ordinary course of Borrower's business as presently conducted; or (e) enter into
any sale, lease or other transaction with any officer, director, employee,
shareholder or affiliate of Borrower on terms that are less favorable to
Borrower than those which might be obtained at the time from persons who are not
an officer, director, employee, shareholder or affiliate of Borrower.

         6.13 Fees and Expenses. Borrower shall pay, on Lender's demand, all
costs, expenses, filing fees and taxes payable in connection with the
preparation, execution, delivery, recording, administration, collection,
liquidation, enforcement and defense of the Obligations, Lender's rights in the

Lender during the course of periodic field examinations of the Collateral and
Borrower's operations, plus a per diem charge at the rate set forth in Section
10.4(g) for Lender's examiners in the field and office, provided, however, that
notwithstanding anything to the contrary contained herein and so long as no
Event of Default has occurred, Borrower and Affiliated Borrower shall not be
liable for per diem charges for Lender's examiners (exclusive of out-of-pocket
expenses) pursuant to this Section 6.13(d) in any contract year (as measured
from the date hereof) in excess of $13,000 per annum; and (e) the costs, fees
and disbursements of in-house and outside counsel to Lender, including but not

time to time, at Borrower's sole expense, Borrower shall execute and deliver or
cause to be executed and delivered to Lender, such agreements, documents and
instruments, including waivers, consents and subordination agreements from
mortgagees or other holders of security interests or liens, landlords or
bailees, and do or cause to be done such further acts as Lender, in its
discretion, deems necessary or desirable to create, preserve, perfect or
validate any security interest of Lender or the priority thereof in the
Collateral and otherwise to effectuate the provisions and purposes of this
Agreement. Borrower hereby authorizes Lender to file financing statements or
amendments against Borrower in favor of Lender with respect to the Collateral,
without Borrower's signature and to file as financing statements any carbon,
photographic or other reproductions of this Agreement or any financing
statements signed by Borrower.

         6.15 Revolving Loans. The Revolving Loans plus Accommodations will not
at any time exceed the Gross Availability unless Lender has consented.

         6.16 Environmental Condition. None of Borrower's properties or assets
has ever been designated or identified in any manner pursuant to any
environmental protection statute as a hazardous waste or hazardous substance
disposal site, or a candidate for closure pursuant to any environmental
protection statute. No lien arising under any environmental protection statute
has attached to any revenues or to any real or personal property owned by
Borrower. Borrower has not received a summons, citation, notice, or directive
from the Environmental Protection Agency or any other federal or state
governmental agency any action or omission by Borrower resulting in the
releasing, or otherwise exposing of hazardous waste or hazardous substances into
the environment. Borrower is, and at all times will be, in compliance (in all
material respects) with all statutes, regulations, ordinances and other legal
requirements pertaining to the production, storage, handling, treatment,
release, transportation or disposal of any hazardous waste or hazardous
substance.

         6.17 Investment Property. Borrower will take any and all actions
reasonably required or requested by Lender, from time to time, to (a) cause
Lender to obtain exclusive control of any investment property in a manner
acceptable to Lender and (b) obtain from any issuers of investment property and

         7.2 Remedies. Upon the occurrence of an Event of Default and at any
time thereafter, Lender shall have all rights and remedies provided in this
Agreement, any other agreements between Borrower and Lender, the Uniform
Commercial Code and other applicable law, all of which rights and remedies may
be exercised without notice to Borrower, all such notices being hereby waived,
except such notice as is expressly provided for hereunder or is not waivable
under applicable law. All rights and remedies of Lender are cumulative and not
exclusive and are enforceable, in Lender's discretion, alternatively,
successively, or concurrently on any one or more occasions and in any order
Lender may determine. Without limiting the foregoing, Lender may (a) accelerate
the payment of all Obligations and demand immediate payment thereof to Lender,
(b) with or without judicial process or the aid or assistance of others, enter
upon any premises on or in which any of the Collateral may be located and take
possession of the Collateral or complete processing, manufacturing and repair of
all or any portion of the Collateral, (c) require Borrower, at Borrower's
expense, to assemble and make available to Lender any part or all of the
Collateral at any place and time designated by Lender, (d) collect, foreclose,
receive, appropriate, setoff and realize upon any and all Collateral, (e) extend
the time of payment of, compromise or settle for cash, credit, return of
merchandise, and upon any terms or conditions, any and all accounts or other
Collateral which includes a monetary obligation and discharge or release the
account debtor or other obligor, without affecting any of the Obligations, (f)
sell, lease, transfer, assign, deliver or otherwise dispose of any and all
Collateral (including, without limitation, entering into contracts with respect
thereto, by public or private sales at any exchange, broker's board, any office
of Lender or elsewhere) at such prices or terms as Lender may deem reasonable,
for cash, upon credit or for future delivery, with the Lender having the right
to purchase the whole or any part of the Collateral at any such public sale, all
of the foregoing being free from any right or equity of redemption of Borrower,
which right or equity of redemption is hereby expressly waived and released by
Borrower. If any of the Collateral is sold or leased by Lender upon credit terms
or for future delivery, the Obligations shall not be reduced as a result thereof
until payment therefor is finally collected by Lender. If notice of disposition
of Collateral is required by law, seven (7) days prior notice by Lender to
Borrower designating the time and place of any public sale or the time after
which any private sale or other intended disposition of Collateral is to be
made, shall be deemed to be reasonable notice thereof and Borrower waives any
other notice. In the event Lender institutes an action to recover any Collateral
or seeks recovery of any Collateral by way of prejudgment remedy, Borrower
waives the posting of any bond which might otherwise be required.

         7.3 Application of Proceeds. Lender may apply the cash proceeds of
Collateral actually received by Lender from any sale, lease, foreclosure or
other disposition of the Collateral to payment of any of the Obligations, in
whole or in part (including reasonable attorneys' fees and legal expenses
incurred by Lender with respect thereto or otherwise chargeable to Borrower) and
in such order as Lender may elect. Borrower shall remain liable to Lender for
the payment of any deficiency together with interest at the highest rate
provided for herein and all costs and expenses of collection or enforcement,
including reasonable attorneys' fees and legal expenses.

         7.4 Lender's Cure of Third Party Agreement Default. Lender may, at its
option, cure any default by Borrower under any agreement with a third party or
pay or bond on appeal any judgment entered against Borrower, discharge taxes,
liens, security interests or other encumbrances at any time levied on or
existing with respect to the Collateral and pay any amount, incur any expense or
perform any act which, in Lender's sole judgment, is necessary or appropriate to
preserve, protect, insure, maintain, or realize upon the Collateral. Lender may
charge Borrower's loan account for any amounts so expended, such amounts to be
repayable by Borrower on demand. Lender shall be under no obligation to effect
such cure, payment, bonding or discharge, and shall not, by doing so, be deemed
to have assumed any obligation or liability of Borrower.

                                                                              30
<PAGE>

SECTION 8.        JURY TRIAL WAIVER; CERTAIN OTHER WAIVERS AND CONSENTS

         8.1 JURY TRIAL WAIVER. BORROWER AND LENDER EACH WAIVE ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING INSTITUTED BY EITHER OF THEM AGAINST
THE OTHER WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE
OBLIGATIONS, THE COLLATERAL, ANY ALLEGED TORTIOUS CONDUCT BY BORROWER OR LENDER,
OR, IN ANY WAY, DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE
RELATIONSHIP BETWEEN BORROWER AND LENDER. IN NO EVENT WILL LENDER BE LIABLE FOR
LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES.

         8.2 Counterclaims. Borrower waives all rights to interpose any claims,
deductions, setoffs or counterclaims of any kind, nature or description in any
action or proceeding instituted by Lender with respect to this Agreement, the
Obligations, the Collateral or any matter arising therefrom or relating thereto,
except compulsory counterclaims.

         8.3 Jurisdiction. Borrower hereby irrevocably submits and consents to
the nonexclusive jurisdiction of the State and Federal Courts located in the
State in which the office of Lender designated in Section 10.6(a) is located and
any other State where any Collateral is located with respect to any action or
proceeding arising out of this Agreement, the Obligations, the Collateral or any
matter arising therefrom or relating thereto. In any such action or proceeding,
Borrower waives personal service of the summons and complaint or other process
and papers therein and agrees that the service thereof may be made by mail
directed to Borrower at its chief executive office set forth herein or other
address thereof of which Lender has received notice as provided herein, service
to be deemed complete five (5) days after mailing, or as permitted under the
rules of either of said Courts. Any such action or proceeding commenced by
Borrower against Lender will be litigated only in a Federal Court located in the
district, or a State Court in the State and County, in which the office of
Lender designated in Section 10.6(a) is located and Borrower waives any
objection based on forum non conveniens and any objection to venue in connection
therewith.

         8.4 No Waiver by Lender. Lender shall not, by any act, delay, omission
or otherwise be deemed to have expressly or impliedly waived any of its rights
or remedies unless such waiver shall be in writing and signed by an authorized
officer of Lender. A waiver by Lender of any right or remedy on any one occasion
shall not be construed as a bar to or waiver of any such right or remedy which
Lender would otherwise have on any future occasion, whether similar in kind or
otherwise.

SECTION 9.        TERM OF AGREEMENT; MISCELLANEOUS

         9.1 Term. This Agreement shall only become effective upon execution and
delivery by Borrower and Lender and shall continue in full force and effect for
a term set forth in Section 10.7 from the date hereof and shall be deemed
automatically renewed for successive terms of two (2) years thereafter unless
terminated as of the end of the initial or any renewal term (each a "Term") by
either party giving the other written notice at least sixty (60) days' prior to
the end of the then current Term.

         9.2 Early Termination. Borrower may also terminate this Agreement by
giving Lender at least thirty (30) days prior written notice (the "Early
Termination Notice") and payment in full of all of the Obligations as provided
herein, including the Early Termination Fee (as hereinafter defined), unpaid
Facility Fee and any other fees, provided that, the Affiliated Borrower
simultaneously terminates the Affiliate Loan Agreements contemporaneously
therewith. Borrower shall have no right to terminate this Agreement as aforesaid
if the Affiliate Loan Agreements are not being simultaneously terminated by the
Affiliated Borrower. Lender shall also have the right to terminate this
Agreement at any time upon or after the occurrence of an Event of Default. If
Lender terminates this Agreement upon or after the occurrence of an Event of
Default, Borrower shall pay Lender forthwith, in full, payment of all
Obligations, including Early Termination Fee, Facility Fee and any other fees.
In view of the impracticality and extreme difficulty of ascertaining actual
damages and by mutual agreement of the parties as to a reasonable calculation of
Lender's lost profits, the early termination fee (the "Early Termination Fee"),
which shall be the joint and several obligation of Borrower and Affiliated
Borrower, shall be equal to:

31
<PAGE>

                  (a)      If such termination occurs on or prior to the first
                           anniversary of this Agreement, three (3%) percent of
                           the Maximum Credit;

                  (b)      If such termination occurs after the first
                           anniversary of this Agreement, but on or prior to the
                           second anniversary of this Agreement, two (2%)
                           percent of the Maximum Credit; and

                  (c)      If such termination occurs after the second
                           anniversary of this Agreement, one (1%) percent of
                           the Maximum Credit.

         Notwithstanding anything to the contrary contained herein, Borrower
acknowledges, confirms and agrees that from and after the date which is thirty
(30) days after receipt by Lender of the Early Termination Notice, Lender shall
have no obligation to make any loans, advances or other financial accommodations
to or for the benefit of Borrower hereunder.

         9.3 Termination Indemnity Deposit. Upon termination of this Agreement
by Borrower, as permitted herein, in addition to payment of all Obligations
which are not contingent, Borrower shall deposit such amount of cash collateral
as Lender reasonably determines is necessary to secure Lender from loss, cost,
damage or expense, including reasonable attorneys' fees, in connection with any
open Accommodations or remittance items or other payments provisionally credited
to the Obligations and/or to which Lender has not yet received final and
indefeasible payment.

         9.4 Notices. Except as otherwise provided, all notices, requests and
demands hereunder shall be (a) made to Lender at its address set forth in
Section 10.6(a) and to Borrower at its chief executive office set forth in
Section 10.6(d), or to such other address as either party may designate by
written notice to the other in accordance with this provision, and (b) deemed to
have been given or made: if by hand, immediately upon delivery; if by telex,
telegram or telecopy (fax), immediately upon receipt; if by overnight delivery
service, one day after dispatch; and if by first class or certified mail, three
(3) days after mailing.

         9.5 Severability. If any provision of this Agreement is held to be
invalid or unenforceable, such provision shall not affect this Agreement as a
whole, but this Agreement shall be construed as though it did not contain the
particular provision held to be invalid or unenforceable.

         9.6 Entire Agreement; Amendments; Assignments. This Agreement contains
the entire agreement of the parties as to the subject matter hereof, all prior
commitments, proposals and negotiations concerning the subject matter hereof
being merged herein. Neither this Agreement nor any provision hereof shall be
amended, modified or discharged orally or by course of conduct, but only by a
written agreement signed by an authorized officer of Lender. This Agreement
shall be binding upon and inure to the benefit of each of the parties hereto and
their respective successors and assigns, except that any obligation of Lender
under this Agreement shall not be assignable nor inure to the successors and
assigns of Borrower.

                                                                              32

<PAGE>

         9.7 Discharge of Borrower. No termination of this Agreement shall
relieve or discharge Borrower of its Obligations, grants of Collateral, duties
and covenants hereunder or otherwise until such time as all Obligations to
Lender have been indefeasibly paid and satisfied in full, including, without
limitation, the continuation and survival in full force and effect of all
security interests and liens of Lender in and upon all then existing and
thereafter-arising or acquired Collateral and all warranties and waivers of
Borrower.

         9.8 Usage. All terms used herein which are defined in the Uniform
Commercial Code shall have the meanings given therein unless otherwise defined
in this Agreement and all references to the singular or plural herein shall also
mean the plural or singular, respectively.

         9.9 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State in which the office of Lender set forth in
Section 10.6(a) below is located.

                                    80%. If the aggregate amount of Borrower's
                                    credits, allowances, discounts, write-offs,
                                    contra-accounts, and other offsets which
                                    reduce the value of accounts, as determined

                                    reduced by the percentage point or points,

                                    Percentage will be subsequently increased by

                                    point that the Dilution Percentage
                                    decreases, but in no event shall the
                                    Eligible Accounts Percentage exceed 80%. The

Exhibit 10.1


                           LOAN AND SECURITY AGREEMENT


         This Agreement is between the undersigned Borrower and the undersigned
Lender concerning loans and other credit accommodations to be made by Lender to
Borrower.

SECTION 1.        PARTIES

         1.1 The "Affiliated Borrower" is HUDSON TECHNOLOGIES COMPANY, and its
successors and assigns.

         1.2 The "Borrower" is the person, firm, corporation or other entity,
identified as the Borrower in Section 10.6(c) and its successors and assigns. If
more than one Borrower is specified in Section 10.6(c), all references to
Borrower shall mean each of them, jointly and severally, individually and
collectively, and the successors and assigns of each.

         1.3 The "Lender" is The CIT Group/Credit Finance, Inc. and its
successors and assigns.

SECTION 2.        LOANS AND OTHER CREDIT ACCOMMODATIONS

         2.1 Revolving Loans. Lender shall, subject to the terms and conditions
contained herein, make revolving loans to Borrower ("Revolving Loans") in
amounts requested by Borrower from time to time, but not in excess of the Net
Availability existing immediately prior to the making of the requested loan and
provided the requested loan would not cause the outstanding Obligations
hereunder plus the then outstanding "Obligations" under and as said quoted term
is defined in the Affiliate Loan Agreements (as defined in Section 10.8 below),
to exceed, in the aggregate, the Maximum Credit.

                  (a)      The "Maximum Credit" is set forth in Section 10.1(a)
hereof.

                  (b) The "Gross Availability" shall be calculated at any time
as (i) the product obtained by multiplying the outstanding amount of Eligible
Accounts by the Eligible Accounts Percentage set forth in Section 10.1(b),
("Accounts Availability"),

                           minus (ii) Reserves, if any.

                  (c) The "Net Availability" shall be calculated at any time as
an amount equal to the Gross Availability minus the aggregate amount of all
then-outstanding Obligations to Lender other than the then outstanding principal
balance of the Term Loan and the Cap/Ex Loans, if any.



                                                                              40

<PAGE>

                  (d) "Eligible Accounts" are accounts created by Borrower in
the ordinary course of its business which are and remain acceptable to Lender
for lending purposes. General criteria for Eligible Accounts are set forth below
but may be revised from time to time by Lender, in its sole judgment, on fifteen
(15) days' prior written notice to Borrower. Lender shall, in general, deem
accounts to be Eligible Accounts if: (1) such accounts arise from bona fide
completed transactions and have not remained unpaid for more than the earlier of
(A) the number of days after the invoice date set forth in Section 10.1(d)(i);
and (B) the number of days after the due date of such invoice set forth in
Section 10.1(d)(ii); (2) the amounts of the accounts reported to Lender are
absolutely owing to Borrower and do not arise from sales on consignment,
guaranteed sale or other terms under which payment by the account debtors may be
conditional or contingent; (3) (A) the account debtor's chief executive office
or principal place of business is located in the United States or Canada (other
than the Province of Quebec) or (B) the account debtor's chief executive office
or principal place of business is located in the Province of Quebec or is
otherwise not located in the United States or Canada ("Foreign Accounts") and
such Foreign Accounts are (x) insured by a credit insurance policy in form,
substance and amount satisfactory to Lender, which policy, together with the
proceeds thereof, shall be duly assigned to Lender, or (y) Borrower and/or such
account debtor has delivered an irrevocable letter of credit issued or confirmed
by a bank satisfactory to Lender, sufficient to cover such Account, in form and
substance satisfactory to Lender, and the original of such letter of credit has
been delivered to Lender or Lender's agent and the issuer thereof notified of
the assignment of the proceeds of such letter of credit to Lender; (4) such
accounts do not arise from progress billings retainages or bill and hold sales;
(5) there are no contra relationships, setoffs, counterclaims or disputes
existing with respect thereto and there are no other facts existing or
threatened which would impair or delay the collectibility of all or any portion
thereof; (6) the goods giving rise thereto were not at the time of the sale
subject to any liens except those permitted in this Agreement; (7) such accounts
are not accounts with respect to which the account debtor or any officer or
employee thereof is an officer, employee or agent of or is affiliated with
Borrower, directly or indirectly, whether by virtue of family membership,
ownership, control, management or otherwise; (8) such accounts are not accounts
with respect to which the account debtor is the United States or any State or
political subdivision thereof or any department, agency or instrumentality of
the United States, any State or political subdivision, unless there has been
compliance with the Assignment of Claims Act or any similar State or local law,
if applicable; (9) Borrower has delivered to Lender or Lender's representative
such documents as Lender may have reasonably requested pursuant to Section 5.8
hereof in connection with such accounts and Lender shall have received a
verification of such account, satisfactory to it, if sent to the account debtor
or any other obligor or any bailee pursuant to Section 5.4 hereof; (10) there
are no facts existing or threatened which might result in any adverse change in
the account debtor's financial condition; (11) such accounts owed by a single
account debtor or its affiliates do not represent more than twenty percent (20%)
of all otherwise Eligible Accounts (accounts excluded from Eligible Accounts
solely by reason of this subsection (11) shall nevertheless be considered
Eligible Accounts to the extent of the amount of such accounts which does not
exceed the applicable percentage stated above, as applicable, of all otherwise
Eligible Accounts); (12) such accounts are not owed by an account debtor who is
or whose affiliates are past due upon other accounts owed to Borrower comprising
more than fifty percent (50%) of the accounts of such account debtor or its
affiliates owed to Borrower; (13) such accounts are owed by account debtors
whose total indebtedness to Borrower does not exceed the amount of any customer
credit limits as may be established, and changed, from time to time by Lender on
notice to Borrower (accounts excluded from Eligible Accounts solely by reason of
this subsection (13) shall nevertheless be considered Eligible Accounts to the
extent the amount of such accounts does not exceed such customer credit limit);
and (14) such accounts are owed by account debtors deemed creditworthy at all
times by Lender.

                  (e)      [Intentionally Omitted]

                  (f) Lender shall have a continuing right to deduct reserves in
determining the Gross Availability ("Reserves"), and to increase and decrease
such Reserves from time to time, if and to the extent that, in Lender's sole
judgment, such Reserves are necessary to protect Lender against any state of
facts which does, or would, with notice or passage of time or both, constitute
an Event of Default or have an adverse effect on any Collateral. Lender may, at
its option, implement Reserves by designating as ineligible a sufficient amount
of accounts or inventory which would otherwise be Eligible Accounts or Eligible
Inventory so as to reduce Gross Availability by the amount of the intended
Reserve. The amount of any reduction in the lending formulas by Lender shall
have a reasonable relationship to the matter which is the basis for such a
reduction.

<PAGE>

                  (g) Subject to the terms and conditions hereof, including but
not limited to the existence of sufficient Gross Availability and Net
Availability, Borrower and Affiliated Borrower, jointly and severally, agree to
borrow sufficient amounts from time to time so that the outstanding Revolving
Loans hereunder plus the outstanding "Revolving Loans" under, and as said quoted
term defined in, the Affiliate Loan Agreements, shall at all times equal or
exceed the principal amount set forth in Section 10.1(e) as the Minimum
Borrowing; provided, that if Borrower and Affiliated Borrower fail to do so,
interest shall nevertheless accrue on the Obligations as if Borrower and
Affiliated Borrower had borrowed such amounts as would have been sufficient to
maintain the outstanding Revolving Loans hereunder and under the Affiliate Loan
Agreements at an amount equal to the Minimum Borrowing (and, on a monthly basis,
Lender shall have the right to charge Borrower's loan account for such
additional interest), and provided further that such accrual shall not impose
upon Lender any obligation to make loans to Borrower or Affiliated Borrower to
increase the outstanding Revolving Loans hereunder or the Affiliate Loan
Agreements to such Minimum Borrowing in the event that sufficient Net
Availability does not then exist.

         2.2 Term Loan and Cap/Ex Loans. Any term loan and the terms of such
loan, made by Lender to Borrower are set forth in Section 10.2 ("Term Loan").

         2.3      Accommodations.

                  (a) Lender may, in its sole discretion, issue or cause to be
issued, from time to time at Borrower's request and on terms and conditions and
for purposes satisfactory to Lender, credit accommodations consisting of letters
of credit, bankers' acceptances, merchandise purchase guaranties or other
guaranties or indemnities for Borrower's account ("Accommodations"). Borrower
shall execute and perform additional agreements relating to the Accommodations
in form and substance acceptable to Lender and the issuer of any Accommodations,
all of which shall supplement the rights and remedies granted herein. Any
payments made by Lender or any affiliate of Lender in connection with the
Accommodations shall constitute additional Revolving Loans to Borrower.

                  (b) In addition to the fees and costs of any issuer in
connection with issuing or administering Accommodations, Borrower shall pay
monthly to Lender, on the first day of each month, a charge on open
Accommodations at the rate per annum set forth in Section 10.3(a) (the
"Accommodation Charges").

                  (c) No Accommodation will be issued unless the full amount of
the Accommodation requested, plus fees and costs for issuance, is less than the
Net Availability existing immediately prior to the issuance of the requested
Accommodation, or if the requested Accommodation would cause the outstanding
Obligations to exceed the Maximum Credit, or cause the open amount of
Accommodations hereunder, together with the open amount of "Accommodations"
under, and as said quoted term is defined in, the Affiliate Loan Agreements to
exceed, at any time, the Accommodation sublimit set forth in Section 10.3(b).

                  (d) All indebtedness, liabilities and obligations of any sort
whatsoever, however arising, whether present or future, fixed or contingent,
secured or unsecured, due or to become due, paid or incurred, arising or
incurred in connection with any Accommodation shall be included in the term
"Obligations", as defined herein, and shall include, without limitation, (i) all
amounts due or which may become due under any Accommodation; (ii) all amounts
charged or chargeable to Borrower or to Lender on account of Borrower, the
Collateral, the Obligations or the Accommodations by any bank, other financial
institution or correspondent bank which opens, issues or is involved with such
Accommodations; (iii) Lender's Accommodation Charges and all fees, costs and
other charges of any issuer of any Accommodation; and (iv) all duties, freight,
taxes, costs, insurance and all such other charges and expenses which may
pertain directly or indirectly to any Obligations or Accommodations or to the
goods or documents relating thereto, unless and to the extent paid directly by
Borrower.

                                                                              42
<PAGE>

                  (e) Borrower unconditionally agrees to indemnify and hold
Lender harmless from any and all loss, claim or liability (including reasonable
attorneys' fees) arising from any transactions or occurrences relating to any
Accommodation established or opened for Borrower's account, the Collateral
relating thereto and any drafts or acceptances thereunder, including any such
loss or claim due to any action taken by an issuer of any Accommodation.
Borrower further agrees to indemnify and hold Lender harmless for any errors or
omissions in connection with the Accommodations, whether caused by Lender, by
the issuer of any Accommodation or otherwise. Borrower's unconditional
obligation to indemnify and hold Lender harmless under this provision shall not
be modified or diminished for any reason or in any manner whatsoever, except for
Lender's willful misconduct or gross negligence. Borrower agrees that any
charges made to Lender by any issuer of any Accommodation shall be conclusive on
Borrower and may be charged to Borrower's account.

                  (f) Lender shall not be responsible for: the conformity of any
goods to the documents presented; the validity or genuineness of any documents;
delay, default, or fraud by the Borrower or shipper and/or anyone else in
connection with the Accommodations or any underlying transaction.

                  (g) Borrower agrees that any action taken by Lender, if taken
in good faith, or any action taken by an issuer of any Accommodation, under or
in connection with any Accommodation, shall be binding on Borrower and shall not
create any resulting liability to Lender. In furtherance thereof, Lender shall
have the full right and authority to clear and resolve any questions of
non-compliance of documents; to give any instructions as to acceptance or
rejection of any documents or goods; to execute for Borrower's account any and
all applications for steamship or airway guarantees, indemnities or delivery
orders; to grant any extensions of the maturity of, time of payment for, or time
of presentation of, any drafts, acceptances, or documents; and to agree to any
amendments, renewals, extensions, modifications, changes or cancellations of any
of the terms or conditions of any of the applications or Accommodations. All of
the foregoing actions may be taken in Lender's sole name, and the issuer thereof
shall be entitled to comply with and honor any and all such documents or
instruments executed by or received solely from Lender, all without any notice
to or any consent from Borrower. None of the foregoing actions described in this
subsection (g) may be taken by Borrower without Lender's express written
consent.

                  (h) Notwithstanding anything to the contrary contained herein,
Borrower shall have no right to request, and Lender shall have no obligation to
issue for Borrower's account any Accommodations.

SECTION 3.        INTEREST AND FEES

         3.1 Interest. (a) Interest on the Revolving Loans shall be payable by
Borrower on the first day of each month, calculated upon the closing daily
balances in the loan account of Borrower for each day during the immediately
preceding month, at the per annum rate set forth as the Interest Rate in Section
10.4(a). The Interest Rate shall increase or decrease by an amount equal to each
increase or decrease, respectively, in the Prime Rate (as defined below),
effective as of the date of each such change. On and after any Event of Default
or termination or non-renewal hereof, interest on all unpaid Obligations shall
accrue at a rate equal to two percent (2%) per annum in excess of the Interest
Rate otherwise payable until such time as all Obligations are indefeasibly paid
in full (notwithstanding entry of any judgment against Borrower or the exercise
of any other right or remedy by Lender), and all such interest shall be payable
on demand. Interest shall in no month be less than the Interest Rate multiplied
by the Minimum Borrowing. In no event shall charges constituting interest exceed
the rate permitted under any applicable law or regulation, and if any provision
of this Agreement is in contravention of any such law or regulation, such
provision shall be deemed amended to conform thereto.

                  (b) The "Prime Rate" is the rate of interest publicly
announced by The Chase Manhattan Bank in New York, New York, or its successors
and assigns from time to time as its prime rate (the Prime Rate is not intended
to be the lowest rate of interest charged by The Chase Manhattan Bank to its
borrowers).

         3.2 Closing Fee. Borrower, jointly and severally with Affiliated
Borrower, shall pay Lender at closing a Closing Fee in the amount set forth in
Section 10.4 (c).

Agreement shall be fully earned at closing and payable in the amounts and on the
dates indicated in Section 10.4(d)(i)(1) and (2), respectively, and which
Facility Fee for each renewal Term of this Agreement shall be fully earned on
the first day of each such renewal Term and payable as set forth in Section

         3.5 Unused Line Fee. Borrower, jointly and severally with Affiliated
Borrower, shall pay Lender monthly, on the first day of each month, in arrears,
an Unused Line Fee for each month during the initial and each renewal Term at
the rate per annum set forth in Section 10.4(f), calculated upon the amount, if
any, by which the Maximum Credit exceeds the average aggregate outstanding daily
principal balance during the preceding month of all Revolving Loans hereunder
and all Revolving Loans, Accommodations, Cap/Ex Loans and any Term Loan under
the Affiliate Loan Agreements.

         3.6 Charges to Loan Account. At Lender's option, all payments of
principal, interest, fees, costs, expenses and other charges provided for in
this Agreement, or in any other agreement now or hereafter existing between
Lender and Borrower, may be charged on the date when due, as principal to any
loan account of Borrower maintained by Lender. Interest, fees for
Accommodations, the Unused Line Fee and any other amounts payable by Borrower to
Lender based on a per annum rate shall be calculated on the basis of actual days
elapsed over a 360-day year.

SECTION 4.        GRANT OF SECURITY INTEREST

         4.1 Grant of Security Interest. To secure the payment and performance
in full of all Obligations, Borrower hereby grants to Lender a continuing
security interest in and lien upon, and a right of setoff against, and Borrower
hereby assigns and pledges to Lender, all of the Collateral, including any
Collateral not deemed eligible for lending purposes.

         4.2 "Obligations" shall mean any and all Revolving Loans and all other

<PAGE>


SECTION 5.        COLLECTION AND ADMINISTRATION

         5.1 Collections. Borrower shall, at Borrower's expense and in the
manner requested by Lender from time to time, direct that remittances and all
other proceeds of accounts and other Collateral be sent to a lock box designated
by and/or maintained in the name of Lender, and deposited into a bank account
now or hereafter selected by Lender and maintained in the name of Lender under
arrangements with the depository bank under which all funds deposited to such
bank account are required to be transferred solely to Lender. Borrower shall
bear all risk of loss of any funds deposited into such account. In connection
therewith, Borrower shall execute such lock box and bank account agreements as
Lender shall specify. Any collections or other proceeds received by Borrower
shall be held in trust for Lender and immediately remitted to Lender in kind.

         5.2 Payments. All Obligations shall be payable at Lender's office set
forth below or at Lender's bank designated in Section 10.6(a) or at such other
bank or place as Lender may expressly designate from time to time for purposes
of this Section. Lender shall apply all proceeds of accounts or other Collateral
received by Lender and all other payments in respect of the Obligations to the
Revolving Loans or to any other Obligations then due, in whatever order or
manner Lender shall determine. For purposes of determining Gross Availability
and Net Availability and for the calculation of the Minimum Borrowing,
remittances and other payments with respect to the Collateral and Obligations
will be treated as credited to the loan account of Borrower maintained by Lender
and Collateral balances to which they relate, upon the date of Lender's receipt
of advice from Lender's bank that such remittances or other payments have been
credited to Lender's account or in the case of remittances or other payments
received directly in kind by Lender, upon the date of Lender's deposit thereof
at Lender's bank, subject to final payment and collection. In computing interest
charges, the loan account of Borrower maintained by Lender will be credited with
remittances and other payments the number of days set forth in Section 10.4(b)
after the day Lender has received advice of receipt of remittances in Lender's
account at Lender's Bank. For purposes of this Agreement, "Business Day" shall
mean any day other than a Saturday, Sunday or any other day on which banks
located in states where Lender has its offices, are authorized to close.

         5.3 Loan Account Statements. Lender shall render to Borrower monthly a
loan account statement. Each statement shall be considered correct and binding
upon Borrower as an account stated, except to the extent that Lender receives,
within sixty (60) days after the mailing of such statement, written notice from
Borrower of any specific exceptions by Borrower to that statement.

         5.4 Direct Collections. Lender may, at any time, whether or not an
Event of Default has occurred, without notice to or assent of Borrower, (a)
notify any account debtor that the accounts and other Collateral which includes
a monetary obligation have been assigned to Lender by Borrower and that payment
thereof is to be made to the order of and directly to Lender, (b) send, or cause
to be sent by its designee, requests (which may identify the sender by a
pseudonym) for verification of accounts and other Collateral directly to any
account debtor or any other obligor or any bailee with respect thereto, and (c)
demand, collect or enforce payment of any accounts or such other Collateral, but
without any duty to do so, and Lender shall not be liable for any failure to
collect or enforce payment thereof; provided that, so long as no Event of
Default has occurred, Lender agrees to use its best efforts to provide Borrower
with notice of any demand, collection or enforcement of payment by Lender
pursuant to this Section 5.4(c). At Lender's request, all invoices and
statements sent to any account debtor, other obligor or bailee, shall state that
the accounts and such other Collateral have been assigned to Lender and are
payable directly and only to Lender.


                                                                              46
<PAGE>

         5.5 Attorney-in-Fact. Borrower hereby appoints Lender and any designee
of Lender as Borrower's attorney-in-fact and authorizes Lender or such designee,
at Borrower's sole expense, to exercise at any times in Lender's or such
designee's discretion all or any of the following powers, which powers of
attorney, being coupled with an interest, shall be irrevocable until all
Obligations have been paid in full: (a) receive, take, endorse, assign, deliver,
accept and deposit, in the name of Lender or Borrower, any and all cash, checks,
commercial paper, drafts, remittances and other instruments and documents
relating to the Collateral or the proceeds thereof, (b) transmit to account
debtors, other obligors or any bailees notice of the interest of Lender in the
Collateral or request from account debtors or such other obligors or bailees at
any time, in the name of Borrower or Lender or any designee of Lender,
information concerning the Collateral and any amounts owing with respect
thereto, (c) notify account debtors or other obligors to make payment directly
to Lender, or notify bailees as to the disposition of Collateral, (d) take or
bring, in the name of Lender or Borrower, all steps, actions, suits or
proceedings deemed by Lender necessary or desirable to effect collection of or
other realization upon the accounts and other Collateral, (e) after an Event of
Default, change the address for delivery of mail to Borrower and to receive and
open mail addressed to Borrower (Lender agrees to use its best efforts to
forward to Borrower any mail addressed to Borrower actually received by Lender
pursuant to this Section 5.5(e) which does not relate to the Obligations, the
Collateral, any transactions arising hereunder or related hereto), (f) after an
Event of Default, extend the time of payment of, compromise or settle for cash,
credit, return of merchandise, and upon any terms or conditions, any and all
accounts or other Collateral which includes a monetary obligation and discharge
or release the account debtor or other obligor, without affecting any of the
Obligations, and (g) execute in the name of Borrower and file against Borrower
in favor of Lender financing statements or amendments with respect to the
Collateral.

         5.6 Liability. Borrower hereby releases and exculpates Lender, its
officers, employees and designees, from any liability arising from any acts
under this Agreement or in furtherance thereof, whether as attorney-in-fact or
otherwise, whether of omission or commission, and whether based upon any error
of judgment or mistake of law or fact, except for willful misconduct or gross
negligence. In no event will Lender have any liability to Borrower for lost
profits or other special or consequential damages.

         5.7 Administration of Accounts. After written notice by Lender to
Borrower and automatically, without notice, after an Event of Default, Borrower
shall not, without the prior written consent of Lender in each instance, (a)
grant any extension of time of payment of any of the accounts or any other
Collateral which includes a monetary obligation, (b) compromise or settle any of
the accounts or any such other Collateral for less than the full amount thereof,
(c) release in whole or in part any account debtor or other person liable for
the payment of any of the accounts or any such other Collateral, or (d) grant

like with respect to any of the accounts or any such other Collateral.

         5.8 Documents. At such times as Lender may request and in the manner
specified by Lender, Borrower shall deliver to Lender or Lender's
representative, as Lender shall designate, copies or original invoices,
agreements, proofs of rendition of services and delivery of goods and other
documents evidencing or relating to the transactions which gave rise to accounts
or other Collateral, together with customer statements, schedules describing the
accounts or other Collateral and/or statements of account and confirmatory
assignments to Lender of the accounts or other Collateral, in form and substance
satisfactory to Lender and duly executed by Borrower. Without limiting the
provisions of Section 5.7, Borrower's granting of credits, discounts,
allowances, deductions, return authorizations or the like will be promptly
reported to Lender in writing. In no event shall any such schedule or
confirmatory assignment (or the absence thereof or omission of any of the
accounts or other Collateral therefrom) limit or in any way be construed as a
waiver, limitation or modification of the security interests or rights of Lender
or the warranties, representations and covenants of Borrower under this
Agreement. Any documents, schedules, invoices or other paper delivered to Lender
by Borrower may be destroyed or otherwise disposed of by Lender six (6) months
after receipt by Lender, unless Borrower requests their return in writing in
advance and makes prior arrangements for their return at Borrower's expense.

at any time, to all of the premises where Collateral is located for the purposes
of inspecting the Collateral, and all Borrower's books and records, and Borrower
shall permit Lender or its designee to make such copies of such books and
records or extracts therefrom as Lender may request. Without expense to Lender,
Lender may use such of Borrower's personnel, equipment, including computer
equipment, programs, printed output and computer readable media, supplies and
premises for the collection of accounts and realization on other Collateral as
Lender, in its sole discretion, deems appropriate. Borrower hereby irrevocably

         5.10 Environmental Audits. From time to time, as reasonably requested
by Lender, at the sole expense of Borrower, Borrower shall provide Lender, or
its designee, complete access to all of Borrower's facilities for the purpose of
conducting an environmental audit of such facilities as Lender or its designees
may deem necessary. Borrower agrees to cooperate with Lender with respect to any
environmental audit conducted by Lender or its designee pursuant to this Section
5.10.

         5.11 Appointment of Affiliated Borrower as Agent for Borrower. The
Borrower hereby irrevocably appoints Affiliated Borrower, and each officer
thereof, as its agent and attorney-in-fact to request Revolving Loans on its

behalf (which may be made to the same account of Affiliated Borrower to which
disbursements of loans to Affiliated Borrower are made), to receive notices and
statements of account from Lender, to take such other actions on its behalf as
is provided hereunder or under any of the other Financing Agreements and
generally to deal with Lender on its behalf, for all matters pertaining to the
financing arrangements under this Agreement.

continuing conditions of the making of loans or other credit accommodations by
Lender to Borrower:

         6.1 Financial and Other Reports. Borrower shall keep and maintain its

Borrower's fiscal year. All of the foregoing shall be in such form and together
with such information with respect to the business of Borrower or any guarantor,
as Lender may in each case request.

                                                                              48


<PAGE>

         6.2 Trade Names. Borrower may from time to time render invoices to
account debtors under its trade names set forth in Section 10.6(g) after Lender
has received prior written notice from Borrower of the use of such trade names
and as to which, Borrower agrees that: (a) each trade name does not refer to
another corporation or other legal entity, (b) all accounts and proceeds thereof
(including any returned merchandise) invoiced under any such trade names are
owned exclusively by Borrower and are subject to the security interest of Lender
and the other terms of this Agreement, and (c) all schedules of accounts and
confirmatory assignments including any sales made or services rendered using the
trade name shall show Borrower's name as assignor and Lender is authorized to
receive, endorse and deposit to any loan account of Borrower maintained by
Lender all checks or other remittances made payable to any trade name of
Borrower representing payment with respect to such sales or services.

         6.3 Losses. Borrower shall promptly notify Lender in writing of any
loss, damage, investigation, action, suit, proceeding or claim relating to a
material portion of the Collateral or which may result in any material adverse
change in Borrower's business, assets, liabilities or condition, financial or
otherwise.

         6.4 Books and Records. Borrower's books and records concerning accounts
and its chief executive office are and shall be maintained only at the address
set forth in Section 10.6(d). Borrower's only other places of business and the
only other locations of Collateral, if any, are and shall be the addresses set
forth in Section 10.6(e) and Section 10.6(f) hereof, except Borrower may change
such locations or open a new place of business after thirty (30) days prior
written notice to Lender. Prior to any change in location or opening of any new
place of business, Borrower shall execute and deliver or cause to be executed
and delivered to Lender such financing statements, financing documents and
security and other agreements as Lender may reasonably require, including,
without limitation, those described in Section 6.14.

         6.5 Title. Borrower has and at all times will continue to have good and
marketable title to all of the Collateral, free and clear of all liens, security
interests, claims or encumbrances of any kind except in favor of Lender and
except, if any, those set forth on Schedule A hereto.

         6.6 Disposition of Assets. Borrower shall not directly or indirectly
without Lender's prior written consent: (a) sell, lease, transfer, assign,
abandon or otherwise dispose of any part of the Collateral or any material
portion of its other assets (other than sales of inventory to buyers in the
ordinary course of business) or (b) consolidate with or merge with or into any
other entity, or permit any other entity to consolidate with or merge with or
into Borrower or (c) form or acquire any interest in any firm, corporation or
other entity.

         6.7 Insurance. Borrower shall at all times maintain, with financially
sound and reputable insurers, insurance (including, without limitation, at the
option of Lender, earthquake and flood insurance) with respect to the Collateral
and other assets. All such insurance policies shall be in such form, substance,
amounts and coverage as may be satisfactory to Lender and shall provide for
thirty (30) days' prior written notice to Lender of cancellation or reduction of
coverage. Borrower hereby irrevocably appoints Lender and any designee of Lender
as attorney-in-fact for Borrower to obtain at Borrower's expense, any such
insurance should Borrower fail to do so and, after an Event of Default, to
adjust or settle any claim or other matter under or arising pursuant to such
insurance or to amend or cancel such insurance. Borrower shall deliver to Lender
evidence of such insurance and a lender's loss payable endorsement satisfactory
to Lender as to all existing and future insurance policies with respect to the
Collateral. Borrower shall deliver to Lender, in kind, all instruments
representing proceeds of insurance received by Borrower. Lender may apply any
insurance proceeds received at any time to the cost of repairs to or replacement
of any portion of the Collateral and/or, at Lender's option, to payment of or as
security for any of the Obligations in any order or manner as Lender determines.

         6.8 Compliance With Laws. Borrower is and at all times will continue to
be in compliance with the requirements of all material laws, rules, regulations
and orders of any governmental authority relating to its business (including
laws, rules, regulations and orders relating to taxes, payment and withholding
of payroll taxes, employer and employee contributions and similar items,
securities, employee retirement and welfare benefits, employee health and
safety, or environmental matters) and all material agreements or other
instruments binding on Borrower or its property. All of Borrower's inventory
shall be produced in accordance with the requirements of the Federal Fair Labor
Standards Act of 1938, as amended and all rules, regulations and orders related
thereto. Borrower shall pay and discharge all taxes, assessments and
governmental charges against Borrower or any Collateral prior to the date on
which penalties are imposed or liens attach with respect thereto, unless the
same are being contested in good faith and, at Lender's option, Reserves are
established for the amount contested and penalties which may accrue thereon.

         6.9 Accounts. With respect to each account deemed an Eligible Account,
except as reported in writing to Lender, Borrower has no knowledge that any of
the criteria for eligibility are not or are no longer satisfied. As to each
account, except as disclosed in writing to Lender at the time such account
arises (a) each is valid and legally enforceable and represents an undisputed
bona fide indebtedness incurred by the account debtor for the sum reported to
Lender, (b) each arises from an absolute and unconditional sale of goods,
without any right of return or consignment, or from a completed rendition of
services, (c) each is not, at the time such account arises, subject to any
defense, offset, dispute, contra relationship, counterclaim, or any given or
claimed credit, allowance or discount, and (d) all statements made and all
unpaid balances and other information appearing in the invoices, agreements,
proofs of rendition of services and delivery of goods and other documentation
relating to the accounts, and all confirmatory assignments, schedules,
statements of account and books and records with respect thereto, are true and
correct and in all respects what they purport to be.

         6.10 Equipment. With respect to Borrower's equipment, Borrower shall
keep the equipment in good order and repair, and in running and marketable
condition, ordinary wear and tear excepted.

         6.11     [Intentionally Omitted].

         6.12 Affiliated Transactions. Borrower will not, without Lender's prior
written consent, directly or indirectly: (a) lend or advance money or property

Borrower, Hudson Holdings, Inc. or Hudson Technologies, Inc.) or assume
indebtedness of, or invest (by capital contribution or otherwise) in any person,
firm, corporation or other entity; or (b) declare, pay or make any dividend,
redemption or other distribution on account of any shares of any class of stock
of Borrower now or hereafter outstanding; or (c) make any payment of the
principal amount of or interest on any indebtedness owing to any officer,
director, shareholder, or affiliate of Borrower; or (d) make any loans or
advances to any officer, director, employee, shareholder or affiliate of
Borrower, except for loans and advances made to Affiliated Borrower in the
ordinary course of Borrower's business as presently conducted; or (e) enter into
any sale, lease or other transaction with any officer, director, employee,
shareholder or affiliate of Borrower on terms that are less favorable to
Borrower than those which might be obtained at the time from persons who are not
an officer, director, employee, shareholder or affiliate of Borrower.


                                                                              50

         6.13 Fees and Expenses. Borrower shall pay, on Lender's demand, all
costs, expenses, filing fees and taxes payable in connection with the
preparation, execution, delivery, recording, administration, collection,
liquidation, enforcement and defense of the Obligations, Lender's rights in the
Collateral, this Agreement and all other existing and future agreements or
documents contemplated herein or related hereto, including any amendments,
waivers, supplements or consents which may hereafter be made or entered into in
respect hereof, or in any way involving claims or defense asserted by Lender or

title insurance and other insurance premiums, appraisal fees, fees incurred in
connection with any environmental report, audit or survey and search fees; (c)

other funds and fees then in effect for returned checks and credit reports; (d)
all expenses and costs heretofore and from time to time hereafter incurred by
Lender during the course of periodic field examinations of the Collateral and
Borrower's operations, plus a per diem charge at the rate set forth in Section
10.4(g) for Lender's examiners in the field and office, provided, however, that
notwithstanding anything to the contrary contained herein and so long as no
Event of Default has occurred, Borrower and Affiliated Borrower shall not be
liable for per diem charges for Lender's examiners (exclusive of out-of-pocket
expenses) pursuant to this Section 6.13(d) in any contract year (as measured
from the date hereof) in excess of $13,000 per annum; and (e) the costs, fees
and disbursements of in-house and outside counsel to Lender, including but not

time to time, at Borrower's sole expense, Borrower shall execute and deliver or
cause to be executed and delivered to Lender, such agreements, documents and
instruments, including waivers, consents and subordination agreements from
mortgagees or other holders of security interests or liens, landlords or
bailees, and do or cause to be done such further acts as Lender, in its
discretion, deems necessary or desirable to create, preserve, perfect or
validate any security interest of Lender or the priority thereof in the
Collateral and otherwise to effectuate the provisions and purposes of this
Agreement. Borrower hereby authorizes Lender to file financing statements or
amendments against Borrower in favor of Lender with respect to the Collateral,
without Borrower's signature and to file as financing statements any carbon,
photographic or other reproductions of this Agreement or any financing
statements signed by Borrower.

         6.15 Revolving Loans. The Revolving Loans will not at any time exceed
the Gross Availability unless Lender has consented.

         6.16 Environmental Condition. None of Borrower's properties or assets
has ever been designated or identified in any manner pursuant to any
environmental protection statute as a hazardous waste or hazardous substance
disposal site, or a candidate for closure pursuant to any environmental
protection statute. No lien arising under any environmental protection statute
has attached to any revenues or to any real or personal property owned by
Borrower. Borrower has not received a summons, citation, notice, or directive
from the Environmental Protection Agency or any other federal or state
governmental agency any action or omission by Borrower resulting in the
releasing, or otherwise exposing of hazardous waste or hazardous substances into
the environment. Borrower is, and at all times will be, in compliance (in all
material respects) with all statutes, regulations, ordinances and other legal
requirements pertaining to the production, storage, handling, treatment,
release, transportation or disposal of any hazardous waste or hazardous
substance.

         6.17 Investment Property. Borrower will take any and all actions

Lender to obtain exclusive control of any investment property in a manner

                                                                              52
<PAGE>

                  (j) Any default or event of default occurs on the part of
Borrower under any agreement, document or instrument to which Borrower is a
party or by which Borrower or any of its property is bound, creating or relating
to any indebtedness of Borrower to any person or entity other than Lender in an
amount exceeding $75,000, if the effect of such default is to accelerate, or to

                  (m) any material change occurs in the nature or conduct of
Borrower's business and such material change remains unremedied for ten (10)
days.

         7.2 Remedies. Upon the occurrence of an Event of Default and at any
time thereafter, Lender shall have all rights and remedies provided in this
Agreement, any other agreements between Borrower and Lender, the Uniform
Commercial Code and other applicable law, all of which rights and remedies may
be exercised without notice to Borrower, all such notices being hereby waived,
except such notice as is expressly provided for hereunder or is not waivable
under applicable law. All rights and remedies of Lender are cumulative and not
exclusive and are enforceable, in Lender's discretion, alternatively,
successively, or concurrently on any one or more occasions and in any order
Lender may determine. Without limiting the foregoing, Lender may (a) accelerate
the payment of all Obligations and demand immediate payment thereof to Lender,
(b) with or without judicial process or the aid or assistance of others, enter
upon any premises on or in which any of the Collateral may be located and take
possession of the Collateral or complete processing, manufacturing and repair of
all or any portion of the Collateral, (c) require Borrower, at Borrower's
expense, to assemble and make available to Lender any part or all of the
Collateral at any place and time designated by Lender, (d) collect, foreclose,
receive, appropriate, setoff and realize upon any and all Collateral, (e) extend
the time of payment of, compromise or settle for cash, credit, return of
merchandise, and upon any terms or conditions, any and all accounts or other
Collateral which includes a monetary obligation and discharge or release the
account debtor or other obligor, without affecting any of the Obligations, (f)
sell, lease, transfer, assign, deliver or otherwise dispose of any and all
Collateral (including, without limitation, entering into contracts with respect
thereto, by public or private sales at any exchange, broker's board, any office
of Lender or elsewhere) at such prices or terms as Lender may deem reasonable,
for cash, upon credit or for future delivery, with the Lender having the right
to purchase the whole or any part of the Collateral at any such public sale, all
of the foregoing being free from any right or equity of redemption of Borrower,
which right or equity of redemption is hereby expressly waived and released by
Borrower. If any of the Collateral is sold or leased by Lender upon credit terms
or for future delivery, the Obligations shall not be reduced as a result thereof
until payment therefor is finally collected by Lender. If notice of disposition
of Collateral is required by law, seven (7) days prior notice by Lender to
Borrower designating the time and place of any public sale or the time after
which any private sale or other intended disposition of Collateral is to be
made, shall be deemed to be reasonable notice thereof and Borrower waives any
other notice. In the event Lender institutes an action to recover any Collateral
or seeks recovery of any Collateral by way of prejudgment remedy, Borrower
waives the posting of any bond which might otherwise be required.

         7.3 Application of Proceeds. Lender may apply the cash proceeds of
Collateral actually received by Lender from any sale, lease, foreclosure or
other disposition of the Collateral to payment of any of the Obligations, in
whole or in part (including reasonable attorneys' fees and legal expenses
incurred by Lender with respect thereto or otherwise chargeable to Borrower) and
in such order as Lender may elect. Borrower shall remain liable to Lender for
the payment of any deficiency together with interest at the highest rate
provided for herein and all costs and expenses of collection or enforcement,
including reasonable attorneys' fees and legal expenses.

         7.4 Lender's Cure of Third Party Agreement Default. Lender may, at its
option, cure any default by Borrower under any agreement with a third party or
pay or bond on appeal any judgment entered against Borrower, discharge taxes,
liens, security interests or other encumbrances at any time levied on or
existing with respect to the Collateral and pay any amount, incur any expense or
perform any act which, in Lender's sole judgment, is necessary or appropriate to
preserve, protect, insure, maintain, or realize upon the Collateral. Lender may
charge Borrower's loan account for any amounts so expended, such amounts to be
repayable by Borrower on demand. Lender shall be under no obligation to effect
such cure, payment, bonding or discharge, and shall not, by doing so, be deemed
to have assumed any obligation or liability of Borrower.

SECTION 8.        JURY TRIAL WAIVER; CERTAIN OTHER WAIVERS AND CONSENTS

         8.1 JURY TRIAL WAIVER. BORROWER AND LENDER EACH WAIVE ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING INSTITUTED BY EITHER OF THEM AGAINST
THE OTHER WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE
OBLIGATIONS, THE COLLATERAL, ANY ALLEGED TORTIOUS CONDUCT BY BORROWER OR LENDER,
OR, IN ANY WAY, DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE
RELATIONSHIP BETWEEN BORROWER AND LENDER. IN NO EVENT WILL LENDER BE LIABLE FOR
LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES.

         8.2 Counterclaims. Borrower waives all rights to interpose any claims,
deductions, setoffs or counterclaims of any kind, nature or description in any
action or proceeding instituted by Lender with respect to this Agreement, the
Obligations, the Collateral or any matter arising therefrom or relating thereto,
except compulsory counterclaims.

         8.3 Jurisdiction. Borrower hereby irrevocably submits and consents to
the nonexclusive jurisdiction of the State and Federal Courts located in the
State in which the office of Lender designated in Section 10.6(a) is located and
any other State where any Collateral is located with respect to any action or
proceeding arising out of this Agreement, the Obligations, the Collateral or any
matter arising therefrom or relating thereto. In any such action or proceeding,
Borrower waives personal service of the summons and complaint or other process
and papers therein and agrees that the service thereof may be made by mail
directed to Borrower at its chief executive office set forth herein or other
address thereof of which Lender has received notice as provided herein, service
to be deemed complete five (5) days after mailing, or as permitted under the
rules of either of said Courts. Any such action or proceeding commenced by
Borrower against Lender will be litigated only in a Federal Court located in the
district, or a State Court in the State and County, in which the office of
Lender designated in Section 10.6(a) is located and Borrower waives any
objection based on forum non conveniens and any objection to venue in connection
therewith.

         8.4 No Waiver by Lender. Lender shall not, by any act, delay, omission
or otherwise be deemed to have expressly or impliedly waived any of its rights
or remedies unless such waiver shall be in writing and signed by an authorized
officer of Lender. A waiver by Lender of any right or remedy on any one occasion
shall not be construed as a bar to or waiver of any such right or remedy which
Lender would otherwise have on any future occasion, whether similar in kind or
otherwise.

SECTION 9.        TERM OF AGREEMENT; MISCELLANEOUS

         9.1 Term. This Agreement shall only become effective upon execution and
delivery by Borrower and Lender and shall continue in full force and effect for
a term set forth in Section 10.7 from the date hereof and shall be deemed
automatically renewed for successive terms of two (2) years thereafter unless
terminated as of the end of the initial or any renewal term (each a "Term") by
either party giving the other written notice at least sixty (60) days' prior to
the end of the then current Term.

         9.2 Early Termination. Borrower may also terminate this Agreement by
giving Lender at least thirty (30) days prior written notice (the "Early
Termination Notice") and payment in full of all of the Obligations as provided
herein, including the Early Termination Fee (as hereinafter defined), unpaid
Facility Fee and any other fees, provided that, the Affiliated Borrower
simultaneously terminates the Affiliate Loan Agreements contemporaneously
therewith. Borrower shall have no right to terminate this Agreement as aforesaid
if the Affiliate Loan Agreements are not being simultaneously terminated by the
Affiliated Borrower. Lender shall also have the right to terminate this
Agreement at any time upon or after the occurrence of an Event of Default. If
Lender terminates this Agreement upon or after the occurrence of an Event of
Default, Borrower, jointly and severally with Affiliated Borrower, shall pay
Lender forthwith, in full, payment of all Obligations, including Early
Termination Fee, Facility Fee and any other fees. In view of the impracticality
and extreme difficulty of ascertaining actual damages and by mutual agreement of
the parties as to a reasonable calculation of Lender's lost profits, the early
termination fee (the "Early Termination Fee"), which shall be the joint and
several obligation of Borrower and Affiliated Borrower, shall be equal to:

                  (a)      If such termination occurs on or prior to the first
                           anniversary of this Agreement, three (3%) percent of
                           the Maximum Credit;

                  (b)      If such termination occurs after the first
                           anniversary of this Agreement, but on or prior to the
                           second anniversary of this Agreement, two (2%)
                           percent of the Maximum Credit; and

                  (c)      If such termination occurs after the second
                           anniversary of this Agreement, one (1%) percent of
                           the Maximum Credit.

         Notwithstanding anything to the contrary contained herein, Borrower
acknowledges, confirms and agrees that from and after the date which is thirty
(30) days after receipt by Lender of the Early Termination Notice, Lender shall
have no obligation to make any loans, advances or other financial accommodations
to or for the benefit of Borrower hereunder.

         9.3 Termination Indemnity Deposit. Upon termination of this Agreement
by Borrower, as permitted herein, in addition to payment of all Obligations
which are not contingent, Borrower shall deposit such amount of cash collateral
as Lender reasonably determines is necessary to secure Lender from loss, cost,
damage or expense, including reasonable attorneys' fees, in connection with any
open Accommodations or remittance items or other payments provisionally credited
to the Obligations and/or to which Lender has not yet received final and
indefeasible payment.

         9.4 Notices. Except as otherwise provided, all notices, requests and
demands hereunder shall be (a) made to Lender at its address set forth in
Section 10.6(a) and to Borrower at its chief executive office set forth in
Section 10.6(d), or to such other address as either party may designate by
written notice to the other in accordance with this provision, and (b) deemed to
have been given or made: if by hand, immediately upon delivery; if by telex,
telegram or telecopy (fax), immediately upon receipt; if by overnight delivery
service, one day after dispatch; and if by first class or certified mail, three
(3) days after mailing.

         9.5 Severability. If any provision of this Agreement is held to be
invalid or unenforceable, such provision shall not affect this Agreement as a
whole, but this Agreement shall be construed as though it did not contain the
particular provision held to be invalid or unenforceable.

         9.6 Entire Agreement; Amendments; Assignments. This Agreement contains
the entire agreement of the parties as to the subject matter hereof, all prior
commitments, proposals and negotiations concerning the subject matter hereof
being merged herein. Neither this Agreement nor any provision hereof shall be
amended, modified or discharged orally or by course of conduct, but only by a
written agreement signed by an authorized officer of Lender. This Agreement
shall be binding upon and inure to the benefit of each of the parties hereto and
their respective successors and assigns, except that any obligation of Lender
under this Agreement shall not be assignable nor inure to the successors and
assigns of Borrower.

         9.7 Discharge of Borrower. No termination of this Agreement shall
relieve or discharge Borrower of its Obligations, grants of Collateral, duties
and covenants hereunder or otherwise until such time as all Obligations to
Lender have been indefeasibly paid and satisfied in full, including, without
limitation, the continuation and survival in full force and effect of all
security interests and liens of Lender in and upon all then existing and
thereafter-arising or acquired Collateral and all warranties and waivers of
Borrower.

         9.8 Usage. All terms used herein which are defined in the Uniform
Commercial Code shall have the meanings given therein unless otherwise defined
in this Agreement and all references to the singular or plural herein shall also
mean the plural or singular, respectively.

         9.9 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State in which the office of Lender set forth in
Section 10.6(a) below is located.

                           the first  (1st)  anniversary  of the date  hereof,
                           the  Maximum  Credit  shall be $6,500,000.

                           (i)      Eligible Accounts Percentage:      Subject
                                    to the succeeding terms of this Section
                                    10.1(b)(i), 80%. If the aggregate amount of
                                    Borrower's credits, allowances, discounts,
                                    write-offs, contra-accounts, and other
                                    offsets which reduce the value of accounts,
                                    as determined by Lender, in its sole
                                    discretion, divided by gross sales
                                    ("Dilution Percentage") is equal to or
                                    greater than 5%; then the Eligible Accounts
                                    Percentage shall be reduced by the
                                    percentage point or points, or fraction
                                    thereof, by which the Dilution Percentage
                                    exceeds 5%; the Eligible Accounts Percentage
                                    will be subsequently increased by one
                                    percentage point for every percentage point
                                    that the Dilution Percentage decreases, but
                                    in no event shall the Eligible Accounts
                                    Percentage exceed 80%. The Dilution
                                    Percentage shall be calculated on a rolling
                                    90 day average.

SECTION 1.        Exercise of Warrant.
                  1.1 The Holder may, at any time and from time to time after
the date hereof, and, before 3:00 P.M., New York City time, on the Expiration
Date, exercise this Warrant in whole or in part for the purchase of such number
of shares of Common Stock as to which this Warrant is then exercisable, at the
Purchase Price. In order to exercise this Warrant in whole or in part, the
Holder shall deliver to the Company at its principal office (a) a written notice
of such Holder's election to exercise this Warrant, in substantially the form
annexed hereto, specifying the number of shares of Common Stock to be purchased,
(b) a certified or official bank check or checks payable to the order of the
Company in an amount equal to the aggregate Purchase Price of the shares of
Common Stock being purchased and (c) this Warrant.
                  1.2 Issuance of Warrant Common Stock. The Company shall, as
promptly as practicable after receipt of the items specified in Section 1.1,
issue to the Holder a single certificate, registered in the name of the Holder,
or Holder's nominee or designee, representing the number of shares of Common
Stock purchased upon such exercise. Such certificate shall be deemed to have
been issued, and such Holder or such nominee or designee shall be deemed for all
purposes to have become the holder of record of such shares of Common Stock, as
of the close of business on the day payment for such shares is received by the
Company as provided in Section 1.1(b). If this Warrant shall have been exercised
only in part, the Company shall, at the time of delivery of said certificate,
deliver to the Holder a new Warrant evidencing the rights of such Holder to
purchase the number of remaining shares of Common Stock called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant. The obligations of the Company to issue shares of Common Stock upon
exercise of this Warrant shall be conditional on the Holder's compliance with
Section 3 hereof. All shares of Common Stock issued upon exercise of this
Warrant shall be validly issued, fully paid and non-assessable. The Company
shall pay all expenses, taxes (other than stock transfer taxes) and other
charges payable in connection with the preparation, issue and delivery of stock
certificates and a new Warrant under this Section 1.


                                                                              64
<PAGE>

                  1.3 Company to Reaffirm Obligations. The Company will, at the
time of the exercise of this Warrant, in full or in part, upon the request of
the Holder, acknowledge in writing its continuing obligation to afford to such
Holder any rights (including, without limitation, the right to registration of
the Warrants and the shares of Common Stock issued and issuable upon exercise)
to which the Holder shall continue to be entitled in accordance with the
provisions of this Warrant, provided that if the Holder of this Warrant shall
fail to make any such request, such failure shall not affect the continuing
obligation of the Company to afford to such Holder any such rights.
                  1.4 Absence of Rights of Holder. This Warrant shall not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company, or to any rights whatsoever except the rights herein expressed, and no
dividend or interest shall be payable or accrue in respect to this Warrant or
the interest represented hereby or the shares issuable upon the exercise hereof
unless and until, and except to the extent that, this Warrant shall be
exercised.

SECTION 2.        Transfer and Exchange; Mutilated or Missing Warrants.
                  2.1 Transfer of Warrant. This Warrant is transferable, subject
to requirements set forth herein, in whole or in part, on the books of the
Company to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant, in substantially the form annexed hereto, duly executed by the Holder
hereof, and funds sufficient to pay any stock transfer taxes payable upon such
transfer. Upon such surrender and payment the Company shall execute and deliver
a new Warrant or Warrants in the name of the assignee or assignees and in the
authorized denominations specified in such instrument of assignment, and this
Warrant shall promptly be cancelled. If and when this Warrant is assigned in
blank, the Company may (but shall not be obligated to) treat the bearer hereof
as the absolute owner of this Warrant for all purposes.


65
<PAGE>

                  2.2 Exchange of Warrant. This Warrant is exchangeable upon the
surrender hereof at the principal office of the Company, for new Warrants in
authorized denominations and of like tenor and date representing in the
aggregate the right to purchase the number of shares of Common Stock then
issuable upon the exercise hereof.
                  2.3 Lost, Stolen, Destroyed or Mutilated Warrant. Upon receipt
by the Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and, in the case of loss, theft or destruction, of
an indemnity satisfactory to it, and, in the case of mutilation upon surrender
and cancellation of this Warrant, the Company will execute and deliver a new
Warrant of like tenor and date, upon reimbursement to the Company for all
reasonable expense incidental thereto. Any such new Warrant executed and
delivered pursuant to this section shall constitute a contractual obligation on
the part of the Company, whether or not this Warrant (so lost, stolen, destroyed
or mutilated) shall thereafter at any time be enforceable by anyone.
                  2.4 Payment of Expenses, Taxes and Charges. Except as
otherwise provided in Section 2.3, the Company shall pay all expenses, taxes
(other than stock transfer taxes) and other charges payable in connection with
the preparation, issue and delivery of Warrants under this Section 2.
                  2.5 Warrant Registration. The Company agrees to maintain, at
its principal office, books for the registration and transfer of the Warrant.
Until transfer on the books of the Company, the Company may treat the registered
holder of this Warrant as the owner hereof for all purposes. The foregoing
provisions of this Section 2 pertaining to transfer or exchange of the Warrant
are subject to the provisions of Section 3.
SECTION 3.        Compliance with Securities Act; Registration, etc.
                  3.1 Restrictions on Transfer. (a) The Holder, by acceptance
hereof, represents and warrants that this Warrant, and upon exercise hereof the
holder of any Warrant Common Stock will represent and warrant that any shares of
Warrant Common Stock, are being acquired for its own account for investment
without any intent to make a public distribution thereof in violation of the
securities laws and that this Warrant and such Warrant Common Stock may not be
sold, encumbered or otherwise transferred except pursuant to an effective
Registration Statement under the Act or an exemption from such registration
requirement and, if an exemption shall be applicable, the Holder or the holder
of Warrant Common Stock shall have delivered an opinion of counsel reasonably
satisfactory to the Company that such registration is not required under the
Act.


                                                                              66
<PAGE>

                           (b) The Holder acknowledges that the Company may
direct the Transfer Agent for the Warrant and the Warrant Common Stock to note a
stop transfer order upon its records in respect of this Warrant and any
certificates evidencing shares of the Warrant Common Stock and that in the event
of any sale, transfer or exchange of this Warrant, any Warrant certificate
issued by the Company shall bear the legend contained on the front part of this
Warrant. In addition, each certificate for shares of Common Stock issued upon
exercise of this Warrant shall bear the following legend:
                                    "The shares represented by this certificate
                           have not been registered under the Securities Act of
                           1933, as amended. Such shares have been acquired by
                           the Holder for its own account for investment and may
                           not be sold, encumbered or otherwise transferred
                           except pursuant to an effective registration
                           statement under such Act or an exemption from such
                           registration requirement, and, if an exemption shall
                           be applicable, the holder shall have delivered an
                           opinion of counsel reasonably satisfactory to the
                           issuer that such registration is not required under
                           said Act."
                           (c) As a condition to any sale, transfer or other
disposition of this Warrant, the transferee shall be required to make the
representations and warranties contained in Section 3.1(a) hereof and
acknowledge the stop transfer order and consent to the legend contained in
Section 3.1(b) hereof.
                  3.2 Registration Rights. If at any time or from time to time
the Company shall determine to register any of its securities (other than by
means of a registration statement on a form (e.g., Form S-8) which by its terms
could not be used for the sale and distribution of any Warrant Common Stock) the
Company will:


67
<PAGE>

                           (a) promptly (but not less than thirty (30) days
prior to the filing of any registration statement) give written notice thereof
(which shall include a list of the jurisdictions, if any, in which the Company
intends to register or qualify such securities under the applicable blue sky or
other state securities laws) to each holder of Warrant Common Stock;
                           (b) if so requested in writing by any holder of
Warrant Common Stock, use its best efforts to effect such registration and any
qualification and compliance relating thereto, including, without limitation,
the execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with the Securities Act and any other governmental
requirements or regulations as would permit or facilitate the sale and
distribution of all Warrant Common Stock, unless, in the opinion of counsel to
the Company reasonably acceptable to the holder of the Warrant Common Stock who
wishes to have them included in such registration statement, registration under
the Act is not required for the sale of such Warrant Common Stock in the manner
proposed by such holders. Notwithstanding the foregoing, if any managing
underwriter of the Company's offering shall advise the Company in writing that,
in its opinion, the distribution of all or a portion of the Warrant Common Stock
(the "Piggy-back Shares") requested to be included in the registration statement
concurrently with the securities being registered by the Company would
materially adversely affect the distribution of such securities by the Company
for its own account, then the holders of such Warrant Common Stock shall delay
their offering and sale of Warrant Common Stock (or the portions thereof so
designated by such managing underwriter) for such period, not to exceed thirty
(30) days, as the managing underwriter shall request. In the event of such
delay, the Company shall file such supplements, post-effective amendments or
separate registration statement, and take any such other steps as may be
necessary to permit such holders to make their proposed offering and sale for a
period of 90 days immediately following the end of such period of delay
("Piggy-back Termination Date"); provided, however, that if at the Piggy-back
Termination Date the Piggy-back Shares are covered by a registration statement
which is, or is required to remain, in effect beyond the Piggy-back Termination
Date, the Company shall maintain in effect the registration statement as it
relates to the Piggy-back Shares for so long as such registration statement
remains or is required to remain in effect for any other such securities.


68

<PAGE>

                           (c) bear all expenses in connection with such
registration, qualification and compliance, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements of the
Company's counsel (but exclusive of the fees and disbursements of legal counsel
retained by holders of Warrant Common Stock) and expenses of any audits incident
to or required by any such registration, qualification or compliance, provided,
that the Company shall not, in any event, be required to bear the cost of any
commissions and compensation paid, and concessions and discounts allowed to,
underwriters, dealers or others performing similar functions in connection with
the sale and distribution of the Warrant Common Stock sold by any holders
thereof.
                  3.3 No Additional Liability. Notwithstanding anything to the
contrary contained in this Section 3 or elsewhere herein, the Company will not,
in any event, be obligated to qualify any Warrant Common Stock covered by a
registration statement under any blue sky or other state securities law if the
Company would by reason thereof be required to qualify to do business in any
jurisdiction where it is not then so qualified.
                  3.4 Notification; Continuation of Effectiveness. In the case
of each registration, qualification and compliance pursuant to this Section 3,
the Company will keep all holders of Warrant Common Stock promptly advised in
writing as to the initiation of proceedings for such registration, qualification
and compliance and as to the completion thereof, and will advise, upon request,
of the progress of such proceedings. The Company will, at its expense, keep such
registration, qualification and compliance effective for a period of 90 days
(subject to Section 3.2(a)(ii) hereof), or for such longer period as may be
required by the Securities Act, by such action as may be necessary or
appropriate to permit the sale or distribution of Warrant Common Stock not
theretofore sold or distributed including, without limitation, the filing of
post-effective amendments and supplements to any registration statement or
prospectus necessary to keep the registration current and for further
qualification under any applicable blue sky or other state securities law, all
as requested by any holder of Warrant Common Stock with respect to which such
registration is being effected.



69
<PAGE>

                  3.5 Information From Holders. The Company may require the
holder of Warrant Common Stock, as a condition to having the Warrant Common
Stock included among the securities as to which any registration, qualification
or compliance referred to in this Section 3 is being effected, to furnish to the
Company such reasonable information regarding the proposed distribution of the
Warrant Common Stock as the Company may request in writing and as shall be
required in connection with such registration, qualification or compliance.
                  3.6 Prospectuses, etc. The Company will, at its expense,
furnish to each holder of Warrant Common Stock with respect to which
registration has been effected, such number of prospectuses, offering circulars
and other documents incident to such registration and related qualification or
compliance as such holder from time to time may reasonably request.
                  3.7 Indemnification. The Company will indemnify each holder of
Warrant Common Stock (and each person, if any, who or which controls such
holder) and each underwriter of the Warrant Common Stock held by or issuable to
such holder, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any registration, qualification or
compliance referred to in this Section 3, or arising out of or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
any violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will reimburse each such holder of Warrant Common Stock (and
each person, if any, who or which controls such holder of Warrant Common Stock)
and each such underwriter for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, provided, that the Company will not be liable in
any such case to the extent that any such claim, loss, damage or liability
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by an instrument duly executed by such
holder of Warrant Common Stock (and each person, if any, who or which controls
such holder of Warrant Common Stock) or underwriter and stated specifically to
be for use therein. The Company may require of such holder of Warrant Common
Stock, as a condition to having such Warrant Common Stock held or issuable to
holder of Warrant Common Stock included among the securities as to which such
registration, qualification or compliance is being effected, that each such
holder of Warrant Common Stock and underwriter will indemnify the Company, its
directors, and its officers who sign the registration statement in respect of
such registration against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any written
information furnished by such holder for inclusion in the registration statement
by such holder of Warrant Common Stock or underwriter, as the case may be, or an
omission (or alleged omission) to state in any such written information a
material fact required to be stated therein or necessary to make the statement
therein not misleading.

                                                                              70
<PAGE>


                  3.8 Notice of Claim, etc. Each party entitled to
indemnification hereunder (the "Indemnified Party") shall give notice to the
party required to provide indemnification (the "Indemnifying Party") promptly
after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the Indemnifying Party to participate
in the defense of any such claim or any litigation resulting therefrom, provided
that counsel for the Indemnifying Party, who shall participate in the defense of
such claim or litigation, shall be acceptable to the Indemnified Party (which
acceptance shall not be unreasonably withheld), and provided further, that the
failure of any Indemnified Party to give notice as provided in this Section 3.8
shall not relieve the Indemnifying Party of its obligation under Section 3.7.
                  3.9 Listing on Securities Exchanges, etc. The Company will, at
its expense, promptly list on each national securities exchange on which Common
Stock is at the time listed, or, if applicable, the NASDAQ National List, upon
official notice of issuance upon the exercise of the Warrant, and maintain such
listing of, all shares of Common Stock from time to time issuable upon the
exercise of the Warrant, and when and if required by the Securities Exchange Act
of 1934 (or any similar statute then in effect) will register thereunder all
shares of Common Stock from time to time so issuable.
                  3.10 Right to Deliver Cash. Notwithstanding the provisions of
this Warrant, the Company shall have the right, in lieu of including the shares
of Warrant Stock in a registration statement pursuant to Section 3.2(a) or
effecting a demand registration pursuant to Section 3.2(b) hereof, to elect to
purchase the Warrant Common Stock to be included in such registration statement
by delivering to a holder of Warrant Common Stock cash in the amount
("Repurchase Amount") equal to the number of shares of Warrant Common Stock to
be included in such registration statement multiplied by an amount equal to the
closing price (or, if applicable, the average of the closing bid and asked
prices) of the Company's Common Stock on the last trading day immediately
preceding the day of notice by the Company pursuant to Section 3.2(a)(1) or the
day preceding the day of demand pursuant to Section 3.2(b), as the case may be.
If the Company elects to exercise its rights hereunder, it should so notify the
holders of Warrant Common Stock within 10 business days of such notice or
demand, as the case may be. The holders shall thereupon promptly deliver the
certificates evidencing shares of Warrant Common Stock to be sold at the time
and place designated in the Company's notice, in duly transferable form,
together with a representation and warranty of good title free and clear of all
liens and encumbrances against receipt from the Company of a bank or certified
check payable to the respective order of such holders in the Repurchase Amount.

SECTION 4. Adjustment of Number and Purchase Price of Shares Covered by Warrant.
                  4.1 Adjustment of Number of Shares. In order to protect the
Holder from dilution with respect to the shares of Common Stock as to which this
Warrant may be exercised, the Company hereby agrees to adjust the number of
shares issuable upon the exercise of this Warrant as follows:
                           (a) In case the outstanding shares of Common Stock
shall be subdivided into a greater or combined into a lesser number of shares of
such stock, the number of shares of Common Stock deliverable upon the exercise
of this Warrant shall be proportionately increased or decreased, as the case may
be, effective at the close of business on the date that such subdivision or
combination shall become effective.
                           (b) If any capital reorganization or reclassification
of the capital stock of the Company, or consolidation or merger of the Company
with another corporation, or the sale of all or substantially all of its assets
to another corporation shall be effected, then, as a condition of such
reorganization, reclassification, consolidation, merger or sale, lawful or
adequate provision shall be made whereby the Holder shall thereafter have the
right to purchase and receive upon the basis and upon the terms and conditions
specified in this Warrant and in lieu of the shares of the Common Stock of the
Company immediately theretofore purchasable and receivable upon the exercise of
this Warrant, such shares of stock, securities or assets as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such Common Stock immediately
theretofore purchasable and receivable upon the exercise of this Warrant had
such reorganization, reclassification, consolidation, merger or sale not taken
place; and in any such case appropriate provision shall be made with respect to
the rights and provisions contained herein (including without limitation
provisions for adjustment of the number of shares issuable upon the exercise of
this Warrant) which shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon exercise of this Warrant. The Company shall not effect any such
consolidation, merger or sale, unless prior to or simultaneously with the
consummation thereof the successor corporation (if other than the Company)
resulting from such consolidation or merger or the corporation purchasing such
assets shall assume by written instrument executed and delivered to the Holder,
the obligation to deliver to the Holder such shares of stock, securities or
assets as, in acceptance with the foregoing provisions, the Holder may be
entitled to purchase.

72
<PAGE>

                  4.2 Adjustment of Purchase Price. In case of any adjustment in
the number of shares issuable upon exercise of this Warrant in accordance with
Section 4.1(a) or Section 4.1(b) the purchase price of such shares shall be
non-commitently adjusted. No increase or decrease in the number of shares of
Common Stock issuable upon exercise of this Warrant shall affect the aggregate
Purchase Price for all shares so issuable, which shall be $129,900.
                  4.3 Fractional Shares. In case at any time the total number of
shares issuable upon exercise of this Warrant shall be increased or decreased
pursuant to any of the provisions of this Section 4, such total number of shares
issuable shall be rounded out to the nearest full share and no adjustment shall
be made with respect to any fractional share of Common Stock which otherwise
would be issuable as a result of any computation made pursuant to this Section.
                  4.4 Certificate. Whenever there is an adjustment in the number
and/or purchase price of shares of Common Stock issuable upon exercise of this
Warrant, as provided herein, the Company shall promptly file with the Holder a
certificate signed by the President or a Vice President of the Company and by
the Treasurer or an Assistant Treasurer or the Secretary or an Assistant
Secretary of the Company, showing in detail the facts requiring such adjustment
and the purchase price per share and number and kind of securities issuable upon
exercise of the Warrant after such adjustment.


                                                                              73
<PAGE>

SECTION 5. Covenants.
                  5.1 Reservation of Shares. The Company shall reserve out of
its authorized shares of Common Stock a number of shares sufficient at all times
to enable it to comply with its obligation to issue shares of fully paid and
non-assessable Common Stock upon the exercise of the Warrant.
                  5.2 Further Action. The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but shall at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the holders of the
Warrants against dilution or other impairment.
                  5.3      Prior Notice of Certain Events.  If the Company shall
take any action:
                           (a) to make any distribution to the holders of Common
Stock;
