warranty, or covenant is more beneficial shall be made by the BANK in its sole
discretion and shall be binding upon the BORROWER.

Citizens Bank NH/Presstek, Inc. Loan Agreement

     NOW, THEREFORE, in consideration of the BANK extending the Loan to the
BORROWER as described hereinbelow, the BANK and the BORROWER hereby agree as
follows:

I. REVOLVING LINE OF CREDIT. The BANK shall make available to the BORROWER the
Revolving Line of Credit Loan in the maximum principal amount of up to Ten
Million Dollars ($10,000,000.00), as evidenced by the Revolving Line of Credit
Promissory Note made by the BORROWER payable to the order of the BANK in the
maximum principal amount of up to Ten Million Dollars ($10,000,000.00) of even
date herewith. The Revolving Line of Credit Loan shall be upon and subject to
the terms and conditions set forth in the Revolving Line of Credit Note, the
other Loan Documents, and this Agreement.

A. Maximum Available Amount. The aggregate maximum amount available to the
BORROWER from time to time under the Revolving Line of Credit Loan shall be up
to Ten Million Dollars ($10,000,000.00).

B. Advances. The Revolving Line of Credit Loan shall be disbursed, advanced,
readvanced, and repaid as provided in the Revolving Line of Credit Note and this
Agreement. BORROWER may request advances in a minimum amount of Two Hundred
Fifty Thousand Dollars ($250,000.00) (each such separate advance being
hereinafter referred to as an "Advance" and all such advances being collectively
referred to as the "Advances") , in writing from time to time in accordance with
the provisions of this Agreement and such other procedures as the BANK may from
time to time specify in an amount such that (i) the aggregate amounts of all
Advances outstanding under the Revolving Line of Credit Loan do not exceed the
maximum available amount as set forth in Section I. A. above, and (ii) there
shall not be more than six (6) separate Advances (including automatic rollover
Advances) outstanding under the Revolving Line of Credit Loan at any one time.
The BANK shall be under no obligation to make any Advance (automatic or
otherwise) at any time or times during which an Event of Default has occurred or
is existing under this Agreement or the Loan Documents, or if any condition
exists which, if not cured, would with the passage of time or the giving of
notice, or both, constitute such an Event of Default. At the time of each
Advance and readvance under the Revolving Line of Credit Loan, BORROWER shall
immediately become indebted to the BANK for the amount thereof. Each such
Advance or readvance may be credited by the BANK to any deposit account of
BORROWER with the BANK, be paid to BORROWER, or applied to any Obligation, as
the BANK may in each instance elect. BORROWER authorizes the BANK to charge any
account which BORROWER maintains with the BANK for any payments which BORROWER
may or must make, or customarily makes, to the BANK from time to time.

C. Review and Repayment. The Revolving Line of Credit Loan shall be subject to
review and, at the sole option and discretion of the BANK, renewal on July 31,
1997, and, if renewed, thereafter on each subsequent anniversary of such date
(July 31, 1997, and each anniversary thereof to which the Revolving Line of
Credit Loan is renewed, being a "Review Date"). IF THE REVOLVING LINE OF CREDIT
LOAN IS NOT RENEWED BY THE



<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

BANK AS AFORESAID ON ANY REVIEW DATE, THE ENTIRE AMOUNT OF OUTSTANDING
PRINCIPAL, ACCRUED INTEREST AND OTHER CHARGES PAYABLE THEREUNDER SHALL BE DUE
AND PAYABLE BY BORROWER ON SUCH REVIEW DATE. BORROWER ACKNOWLEDGES AND AGREES
THAT THE BANK HAS NO OBLIGATION OR COMMITMENT TO RENEW THE REVOLVING LINE OF
CREDIT LOAN ON ANY REVIEW DATE. NOTWITHSTANDING THE FOREGOING, OR ANY PROVISION
OF THE REVOLVING LINE OF CREDIT NOTE, ANY OF LOAN DOCUMENTS OR HEREIN TO THE
CONTRARY, THE REVOLVING LINE OF CREDIT LOAN IS AND SHALL BE PAYABLE UPON DEMAND
BY THE BANK UPON THE OCCURRENCE OF AN EVENT OF DEFAULT.

D. Interest Rate. The principal balance of each Advance outstanding from time to
time under the Revolving Line of Credit Loan shall, unless BORROWER has
otherwise elected the Prime Rate as provided herein below, bear interest during
the Advance Term (as hereinafter defined) therefor at a fixed rate equal to the
LIBOR Rate (as hereinafter defined) plus one and three-quarters percent (1.75%)
per annum. As used herein, for each Advance the term "LIBOR Rate" shall mean the
rate as determined by the BANK on the basis of the offered rates for deposits in
U.S. dollars for a thirty (30) day period which appear on the Telerate page 3750
or Reuter's LIBOR page as of 11:00 a.m. London time on the date that is two (2)
Banking Days preceding the first day of the Advance Term for such Advance. If
such rate does not appear on the Telerate page 3750 or Reuter's LIBOR page, the
rate for that date will be determined on the basis of the offered rates for
deposits in U.S. dollars for a thirty (30) day period which are offered by four
major banks in the London interbank market at approximately 11:00 a.m. London
time on the date that is two (2) Banking Days preceding the first day of the
Advance Term for such Advance. The principal London office of each of the four
major BANKS in the London interbank market will be requested to provide a
quotation of its U.S. dollar deposit offered rate. If at least two such
quotations are provided, the rate for that date will be the arithmetic mean of
all such quotations. If fewer than two quotations are provided as requested, the
rate for that date will be determined on the basis of the rates quoted for loans
in U.S. dollars to leading European BANKS for a thirty (30) day period offered
by major BANKS in New York City at approximately 11:00 a.m., New York City time,
on the date that is two (2) Banking Days preceding the first day of the Advance
Term for such Advance. In the event that the Board of Governors of the Federal
Reserve System shall impose a Reserve Percentage on the BANK with respect to
LIBOR deposits of the BANK, then for any period during which such Reserve
Percentage shall apply, the LIBOR Rate shall be equal to the amount determined
above divided by an amount equal to 1 minus the Reserve Percentage actually
maintained by the BANK. In the event of any such imposition of a Reserve
Percentage, the BORROWER may elect by written notice to the BANK to have the
entire principal amount of all outstanding Advances bear interest at the Prime
Rate (as hereinafter defined). For purposes hereof, "Reserve Percentage" means
the rate (expressed as a decimal) at which the BANK is required to maintain
reserves under Regulation D of the Board of Governors of the Federal Reserve
System against Eurodollar liabilities outstanding. Interest shall be calculated
and charged daily on the basis of actual days elapsed over a three hundred sixty
(360) day banking year. The "Advance Term" for each Advance shall be a thirty
(30) day period beginning on the

                                       3

<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

Banking Day elected by the BORROWER for such Advance to be made. BORROWER shall
notify BANK in writing at least two (2) Banking Days in advance of the date upon
which the BORROWER desires the Advance to be made. BORROWER's notice to BANK as
aforesaid shall specify the amount requested to be advanced under the Revolving
Line of Credit Loan and the date such Advance is to be made (which must be a
Banking Day). The entire principal amount of each outstanding Advance shall
either be repaid in full as of the end of the Advance Term therefor or, if not
repaid in full, shall automatically (and without requirement of written
notification by BORROWER) be deemed a new Advance as to which (i) the Advance
Term shall commence as of the next day after last day of the Advance Term then
ending and (ii) the interest rate therefor shall be equal to a fixed rate equal
to the LIBOR Rate as of two (2) Banking Days preceding the first day of such new
Advance Term plus one and three-quarters percent (1.75%) per annum. As used
herein, the term "Prime Rate" shall mean the rate published by The Wall Street
Journal from time to time under the category "Prime Rate: The Base Rate of
Corporate Loans posted by at least 75% of the Nation's 30 Largest Banks" (the
lowest of the rates so published if more than one rate is published under this
category at any given time) or such other comparable index rate selected by the
BANK in its sole discretion if The Wall Street Journal ceases to publish such
rate. The BORROWER acknowledges that the Prime Rate is used for reference
purposes only as an index and is not necessarily the lowest interest rate
charged by the BANK on commercial loans. Each time the Prime Rate changes the
interest rate under the Revolving Line of Credit Loan shall change
contemporaneously with such change in the Prime Rate. Interest shall be
calculated and charged daily on the basis of actual days elapsed over a three
hundred sixty (360) day banking year.

E. Change in Circumstances; Prepayments. Notwithstanding the foregoing, if as a
result of any change in any foreign or United States law or regulation (or
change in the interpretation thereof) it is determined by BANK that it is
unlawful to maintain an Advance, or if any central BANK or governmental
authority (foreign or domestic) shall assert that it is unlawful to maintain a
Advance, then such Advance shall terminate and, if not then repaid in full,
shall bear interest at the Prime Rate. If for any reason an Advance is
terminated or prepaid prior to the end of an Advance Term, the BORROWER shall,
upon demand by BANK, pay to BANK any amounts required to compensate BANK for any
losses, costs, or expenses which it may reasonably incur as a result of such
termination or prepayment, including, without limitation, any losses, costs, or
expenses incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by the BANK to fund or maintain such Advance. For purposes
hereof, a "Banking Day" means a day upon which banks are open for business to
the general public in New Hampshire, and upon which dealings are carried on and
banks are open for business in the London interbank market.

F. Purposes. Amounts advanced to BORROWER under the Revolving Line of Credit
Loan shall be used solely for BORROWER's ordinary working capital requirements
and general corporate purposes.

                                       4

Citizens Bank NH/Presstek, Inc. Loan Agreement

II. FEES. In addition to such other fees as are provided in this Agreement and
in the other Loan Documents, BORROWER agrees to pay the BANK the fees set forth
on Schedule II attached hereto.

III. PAYMENTS. All payments made by the BORROWER of principal and interest on
the Loan, and other sums and charges payable under the Loan Documents, shall be
made to the BANK in accordance with the terms of the respective Loan Documents
in lawful United States of America currency at its office set forth above, or by
the debiting by the BANK of the demand deposit account(s) in the name of the
BORROWER at the BANK, or in such other reasonable manner as may be designated by
the BANK in writing to the BORROWER.

IV. SECURITY. The Loan and all other Obligations of the BORROWER to the BANK,
whether now existing or hereafter arising, shall at all times be guaranteed by
the Guarantor pursuant to the Guaranty and be secured by perfected first
security interests in and liens on the Collateral (as hereinafter defined),
which security interests and liens shall continue until payment in full of all
amounts outstanding under the Loan and the other Obligations. The term
"Collateral" as used herein shall be deemed to include all property and assets
of the BORROWER and the Guarantor secured, mortgaged, pledged, assigned, or
otherwise encumbered or covered by any of the Loan Documents, including, but not
limited to the Security Agreement. The BORROWER covenants and agrees to take
such further actions and to execute such additional documents as may be
necessary from time to time to enable the BANK to obtain and maintain the
security interests and liens arising under the Loan Documents. If the Collateral
includes accounts and account receivables of BORROWER, then, in addition to such
other rights and remedies as are provided the BANK under the Loan Documents, the
BORROWER agrees that BANK may communicate with account debtors in order to
verify the existence, amount, and terms of any such accounts and accounts
receivable. Upon an Event of Default, BANK may notify account debtors of the
BANK's security interest and require that payments on accounts and account
receivables be made directly to BANK, and, after an Event of Default, upon the
request of BANK, BORROWER shall notify account debtors and indicate on all
billings that payments and returns are to be made directly to BANK. In
furtherance of the foregoing, BORROWER hereby appoints BANK as attorney
irrevocable with full power to collect, compromise, endorse, sell, or otherwise
deal with the BORROWER's accounts and account receivables or proceeds thereof
and to perform the terms of any contract in order to create accounts and account
receivables in BANK's name or in the name of BORROWER.

V. SUBORDINATION AND STANDBY OF DEBT. The BORROWER covenants and agrees that all
existing debt of BORROWER to any officer, director, or shareholder of BORROWER,
and all future debt if permitted hereunder of BORROWER to any officer, director,
or shareholder of a BORROWER, shall be and hereby is, without need for further
writing, made subject and subordinate to the prior payment and performance of
all the Loan

                                       5
<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

and other Obligations of BORROWER. In furtherance of the foregoing, the BORROWER
shall provide such subordinations, certificates, and other documents, and shall
mark its corporate books, records, stock certificates, and ledgers, as the BANK
may reasonably request from time to time, in form and substance satisfactory to
BANK and BANK's counsel, evidencing the subordination of all debt of BORROWER to
any officer, director, or shareholder of a BORROWER, whether now existing or
hereafter arising, in accordance with the covenants of BORROWER hereunder.

VI. CONTINUING REPRESENTATIONS AND WARRANTIES. BORROWER warrants and represents
to the BANK that so long as any of the Obligations are outstanding:

A. Good Standing. BORROWER is duly organized, validly existing, and in good
standing under the laws of its state of organization and is qualified to do
business in all other jurisdictions where the nature of the business conducted
or property owned by BORROWER require it to be so qualified. BORROWER has the
power to own its properties and to carry on its business as now being conducted.

B. Authority. BORROWER has full power and authority to enter into this Agreement
and to borrow under the Loan Documents, to execute and deliver the Loan
Documents and to incur the obligations provided for herein and in the Loan
Documents, all of which have been duly authorized by all proper and necessary
corporate or other action. The persons executing the Loan Documents on behalf of
the BORROWER have been duly authorized to do so.

C. Binding Agreement. This Agreement and the Loan Documents constitute the valid
and legally binding obligations of the BORROWER, enforceable in accordance with
their terms.

D. Litigation. Except for the lawsuits disclosed on Schedule VI. D. attached
hereto (the "Current Lawsuits"), there are no suits or proceedings of any kind
or nature pending or, to the knowledge of the BORROWER, threatened against or
affecting the BORROWER or its assets which, if adversely determined, would have
a material adverse affect on the financial condition or business of the BORROWER
or the Guarantor and which have not been disclosed in writing to the BANK.

E. Conflicting Agreements; Consents. There is no charter, bylaw, preference
stock, or trust provision of the BORROWER, and no provision(s) of any existing
mortgage, indenture, contract or agreement binding on the BORROWER or affecting
its property, which would conflict with, have a material adverse affect upon, or
in any way prevent the execution, delivery, or performance of the terms of this
Agreement or the Loan Documents. BORROWER is not required to obtain any order,
consent, approval, authorization of any person, entity, or governmental
authority in connection with or as a condition to the execution, delivery, and
performance of this Agreement or the Loan Documents or the granting of the
security interests and liens in the Collateral. Notwithstanding the foregoing,
the BANK acknowledges that the BORROWER's collateral assignment to the BANK of,
and granting of security interests to BANK in, amounts now due and hereafter
becoming due

                                       6

<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

under various agreements and contracts to which BORROWER is a party may, in
certain circumstances, be contrary to or in violation of the express terms,
conditions, or limitations of such contracts and agreements. BANK agrees that
any such violations shall not be deemed a breach of the BORROWER's
representations under this Section VI. E. or of BORROWER's similar
representations or covenants elsewhere in this Agreement or any of the Loan
Documents. The foregoing shall in no manner limit the effect of the collateral
assignment under the Security Agreement by the BORROWER to the BANK of the
accounts arising under such contracts or agreements for the payment of money now
due or hereafter becoming due to the BORROWER thereunder, or of the security
interests of the BANK in such accounts, or of the BANK's rights with respect
thereto under the Security Agreement.

F. Financial Condition. The financial statements delivered to the BANK by the
BORROWER have been and shall be prepared in accordance with generally accepted
accounting principles, consistently applied, are and will be complete and
correct, and fairly present the financial condition and results of the BORROWER.
Other than those liabilities disclosed in writing to the BANK, including, but
not limited to, the Current Lawsuits, there are no liabilities, direct or
indirect, fixed or contingent, of the BORROWER which are not reflected in the
financial statements or in the notes thereto which would be required to be
disclosed therein and there has been no material adverse change in the financial
condition or operations of the BORROWER since the date of such financial
statements.

G. Taxes. BORROWER has filed all federal, state and local tax returns required
to be filed by them and have paid all taxes shown by such returns to be due and
payable on or before the due dates thereof.

H. Solvency. The present fair saleable value of the BORROWER's assets is greater
than the amount required to pay its total liabilities; the amount of the
BORROWER's capital is adequate in view of the type of business in which it is
engaged.

I. Full Disclosure. None of the information with respect to the BORROWER which
has been furnished to the BANK in connection with the transactions contemplated
hereby is false or misleading with respect to any material fact, or omits to
state any material fact necessary in order to make the statements therein not
misleading.

J. Employee Benefit Plans. To BORROWER's knowledge, all Plans (as hereinafter
defined) which are pension plans as defined in Section 3(2) of the Employment
Retirement Income Security Act of 1974, as amended ("ERISA"), qualify under
Section 401 of the Internal Revenue Code of 1986 (as amended, the "IRC"), and
all Plans are in compliance with the provisions of the IRC and ERISA, and have
been administered in accordance with their terms. The term "Plan" means any
pension plan, as defined in Section 3(2) of ERISA and any welfare plan, as
defined in Section 3(1) of ERISA, which is sponsored, maintained or contributed
to by BORROWER or any commonly controlled entity, or in respect of which
BORROWER or a commonly controlled entity is an "employer" as defined in Section
3(5) of ERISA. To BORROWER's knowledge, and except with respect to events which
would not have a material adverse affect on BORROWER's business or financial
condition:

                                       7

Citizens Bank NH/Presstek, Inc. Loan Agreement

     (i) Prohibited Transactions. None of the Plans has participated in, engaged
in or been a party to any non-exempt "prohibited transaction" as defined in
ERISA or the IRC, and no officer, director or employee of BORROWER has committed
a breach of any of the responsibilities or obligations imposed upon fiduciaries
by Title I or ERISA.

     (ii) Claims. There are no contested claims, pending or threatened,
involving any Plan which is a pension plan by a current or former employee (or
beneficiary thereof) of BORROWER, nor is there any reasonable basis to
anticipate any claims involving any such Plan.

     (iii) Reporting and Disclosure Requirements. There have been no violations
of any reporting or disclosure requirements with respect to any Plan and no such
Plan has violated applicable law, including but not limited to ERISA and the
IRC.

     (iv) "Accumulated Funding Deficiency"; Reportable Event. No Plan which is a
defined benefit pension plan has (a) incurred an "accumulated funding
deficiency" (within the meaning of Section 412(a) of the IRC), whether or not
waived, (b) been a plan with respect to which a Reportable Event (to the extent
that the reporting of such events to the Pension Benefit Guaranty Corporation
(the "PBGC") within thirty (30) days of the occurrence has not been waived) has
occurred and is continuing, or (c) been a Plan with respect to which there
exists conditions or events which have occurred presenting a risk of termination
by PBGC.

     (v) Multiemployer Plan. No Plan which is a multiemployer pension plan (as
defined in Section 414(f) of the IRC) to which BORROWER contributes has been a
plan with respect to which BORROWER has received any notification that such
Multiemployer Plan is in reorganization or has been terminated within the
meaning of Title IV of ERISA and no such Multiemployer Plan is reasonably
expected to be in reorganization or to be terminated within the meaning of Title
IV of ERISA. BORROWER has not withdrawn from, or incurred any withdrawal
liability to, any multiemployer plan.

     (vi) COBRA. There has been no violation of the applicable requirements of
Section 4980B of the IRC pertaining to COBRA continuation coverage with respect
to any Plan.

         (vii) Employee Welfare Benefit Plans. No Plan which is a medical,
dental, health, disability, insurance or other plan or arrangement, whether oral
or written, which constitutes an "employee welfare benefit plan" as defined in
Section 3(1) of ERISA, has any unfunded accrued liability or provides benefits
to former employees or retirees (except as may be required by COBRA).

K. Location of Records. All of the books and records or true and complete copies
thereof relating to the accounts and contracts of the BORROWER are and will be
kept at BORROWER's principal place of business located at the address first set
forth above (the "Premises").

                                       8

L. Compliance with Laws. The BORROWER is in compliance in all material respects
with all laws and governmental rules and regulations applicable to the
Collateral and to its business, properties and assets.

M. Hazardous Waste. No Hazardous Waste (as hereinafter defined) has been
generated, stored or treated on any of the premises occupied by BORROWER, except
in compliance with all applicable laws. No Hazardous Waste has ever been, is
being, is intended to be, or is threatened to be spilled, released, discharged,
disposed, placed or otherwise caused to be found in the soil or water in, under,
or upon any of the premises occupied by the BORROWER. The BORROWER agrees to
indemnify and hold the BANK harmless from and against any claims, damages,
liabilities (whether joint or several), losses and expenses (including, without
limitation, attorneys' fees) incurred by the BANK as a result of the breach of
these representations. For the purpose of this Agreement, the term "Hazardous
Waste" means "hazardous waste", "hazardous material", "hazardous substance", and
"oil" as presently defined in the Resource Conservation and Recovery Act, the
Comprehensive Environmental Response, Compensation and Liability Act, the
Hazardous Material Transportation Act, the Federal Water Pollution Control Act,
and corresponding state and local statutes, ordinances, and regulations, as such
statutes, ordinances and regulations may be amended, or as defined in any
federal or state regulation adopted pursuant to such acts.

N. Title to Collateral. BORROWER, or Guarantor, as the case may be, has and will
at all times have good and marketable title to the Collateral, free and clear
from any liens, security interests, mortgages, encumbrances, pledges or other
right, title or interest of any other person or entity, except those arising
under the Loan Documents or disclosed to the BANK in the Security Agreement
("Permitted Encumbrances").

O. Employees. BORROWER has complied with all laws relating to the employment of
labor, including any provisions thereof relating to ERISA, wages, hours,
collective bargaining, the payment of social security and similar taxes, equal
employment opportunity, employment discrimination and occupational safety and
health, and is not liable for any arrears of wages or any taxes or penalties for
failure to comply with any of the foregoing.

VII. AFFIRMATIVE COVENANTS. Until payment in full of all indebtedness under the
Loan and the other Obligations, BORROWER, agrees that, unless the BANK shall
otherwise consent in writing, it will:

A. Prompt Payment. Pay promptly, subject to any applicable cure or grace period,
when due all amounts due and owing to the BANK.

B. Use of Proceeds. Use the proceeds of the Loan only for business purposes and
will furnish the BANK with such evidence as it may reasonably require with

BORROWER within one hundred twenty (120) days after the end of each fiscal year;

quarters of each fiscal year;

3. Financial statements of BORROWER, including a balance sheet and statement of
income, as prepared by management in accordance with generally accepted
accounting principles, within ninety (90) days of the end of the fourth fiscal

legal existence.

E. Maintenance of Business. Do or cause to be done all things necessary to

F. Maintenance of Insurance. Keep all of BORROWER's properties (specifically

or damage by fire and such other casualties and hazards as the BANK may specify
from time to time; maintain adequate Workman's Compensation Insurance under
applicable laws, Comprehensive General Public Liability Insurance, directors'
and officers' liability insurance, and products liability insurance; and
maintain adequate insurance covering such other risks as the BANK may reasonably
specify from time to time hereafter. All insurance required hereunder shall be
effected by valid and enforceable policies issued by insurers of recognized
responsibility authorized to transact business within the state of New
Hampshire, and shall, inter alia, (1) name the BANK as a loss payee, (2) provide
that no action of the BORROWER shall void any such policy as to the BANK, and
(3) provide that the BANK shall be notified in writing of any proposed
cancellation of such policy at least thirty (30) days in advance thereof and
will have the opportunity to correct any deficiencies justifying such proposed
cancellation. For the purposes of this Paragraph, an insurance policy shall be
deemed to be "adequate" if it provides coverage against such risks and in such
amounts as is customarily carried by owners of similar businesses and
properties.

G. Inspection by the BANK. BORROWER agrees that the BANK may conduct regular
field examination audits of the BORROWER's books, records, accounts, inventory,
and other property up to two (2) times during each of BORROWER's fiscal years

charged or incurred by BANK for such audits. BORROWER also agrees that upon

normal business hours, it shall permit any person designated by the BANK to
inspect any of BORROWER's properties, including its books, records, and accounts
(and including the making of copies thereof and extracts therefrom) all at
BANK's cost and expense. After and during the continuance of an Event of
Default, BORROWER also agrees that the BANK may conduct field examination audits
of the BORROWER's books, records, accounts, inventory, and other property as
often as the BANK deems necessary and appropriate in its sole discretion and
that BORROWER shall pay the BANK all reasonable fees, costs, and expenses
charged or incurred by BANK for such audits without limitation as to amount. All
inspections and audits by BANK pursuant hereto shall be conducted in a manner

respect to matters affecting employee welfare, benefit or retirement programs.

payable without further demand, notice or protest, all of which are hereby
expressly waived. Thereafter, the BANK may proceed to protect and enforce its
rights, at law, in equity, or otherwise, against the BORROWER, the Guarantor,
and any other endorser or guarantor of the BORROWER's Obligations, either
jointly or severally, and may proceed to liquidate and realize upon any of its
Collateral in accordance with the rights of a secured party under the Uniform

between any guarantor or endorser of the BORROWER's Obligations to the BANK, and
to apply the proceeds thereof to payment of the Obligations of the BORROWER to
the BANK in such order and in such manner as the BANK, in its sole discretion,
deems appropriate.

XI.  MISCELLANEOUS PROVISIONS.

A. Entire Agreement; Waivers. This Agreement, the Schedules hereto, and the Loan
Documents together constitute the entire agreement between the BORROWER and the
BANK and no covenant, term, condition or other provision thereof nor any default
in connection therewith may be waived except by an instrument in writing, signed
by the BANK and delivered to the BORROWER. The BANK's failure to exercise or
enforce any of its rights, powers or privileges under this Agreement or the Loan
Documents shall not operate as a waiver thereof. In the event of any conflict
between the terms, covenants, conditions and restrictions contained in the Loan
Documents, the term, covenant, condition or restriction which confers the
greatest benefit upon the BANK shall control. The determination as to which
term, covenant, condition or restriction is more beneficial shall be made by the
BANK in its sole discretion.

B. Remedies Cumulative. All remedies provided under this Agreement and the Loan
Documents or afforded by law shall be cumulative and available to the BANK until
all of the BORROWER's Obligations to the BANK have been paid in full.

C. Survival of Covenants. All covenants, agreements, representations and
warranties made in this Agreement and in the Loan Documents shall be deemed to
be material and to have been relied on by the BANK, notwithstanding any
investigation made by the BANK or in its behalf, and shall survive the execution
and delivery of this Agreement and the Loan Documents. All such covenants,
agreements, representations and warranties shall bind and inure to the benefit
of the BORROWER's and the BANK's successors and assigns, whether so expressed or
not.

D. Governing Law; Jurisdiction. This Agreement and the Loan Documents shall be
construed and their provisions interpreted under and in accordance with the laws
of the State of New Hampshire. The BORROWER, to the extent they may legally do
so, hereby consents to the jurisdiction of the courts of the State of New
Hampshire and the United States District Court for the State of New Hampshire
for the purpose of any suit, action or other

                                       16

<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

proceeding arising out of any of their obligations hereunder or with respect to
the transactions contemplated hereby, and expressly waive any and all objections
they may have to venue in any such courts.

E. Assurance of Execution and Delivery of Additional Instruments. The BORROWER
agrees to execute and deliver, or to cause to be executed and delivered, to the
BANK all such further instruments, and to do or cause to be done all such
further acts and things, as the BANK may reasonably request or as may be
necessary or desirable to effect further the purposes of this Agreement and the
Loan Documents.

F. Waivers and Assents. The BORROWER, and any guarantor or endorser of the
BORROWER's Obligations to the BANK, hereby waive, to the fullest extent
permitted by law, all rights to marshalling of assets and all rights to demand,
notice, protest, notice of acceptance of this Agreement and the Loan Documents,
notice of the Loan made, credit extended, Collateral received or delivered or
other action taken in reliance hereon and all other demands and notices of any
description with respect both to the Loan Documents and the Collateral. The
BORROWER assents to any extension or postponement of the time of payment or any
other indulgence, to any substitution, exchange or release of Collateral, to the
addition or release of any party or person primarily or secondarily liable, to
the acceptance of partial payments thereon and the settlement, compromising or
adjusting of any thereof, all in such manner and at such time or times as the
BANK may deem advisable.

G. No Duty of the BANK With Respect to the Collateral. Except as may otherwise
be specifically required under the Uniform Commercial Code, the BANK shall have
no duty as to the collection or protection of Collateral or any income thereon,
nor as to the preservation of rights against prior parties, nor as to the
preservation of any rights pertaining thereto, beyond the safe custody thereof.

H. Election of the BANK. The BANK may exercise its rights with respect to
Collateral without resorting or regard to other collateral or sources of
reimbursement for the Obligations of BORROWER to the BANK.

I. Assignment. If at any time, by assignment or otherwise, the BANK transfers
its rights in any of the BORROWER's Obligations and its rights in Collateral
therefor, in whole or in part, such transfer shall carry with it the powers and
rights of the BANK under this Agreement, the Loan Documents, and the Collateral
so transferred and the transferee shall become vested with such powers and
rights whether or not they are specifically referred to in the instrument
evidencing the transfer. If, and to the extent that the BANK retains such rights
and Collateral, the BANK shall continue to have the rights and powers herein set
forth with respect thereto. This Agreement and the Loan Documents shall be
binding upon and inure to the benefit of the BANK, the BORROWER and the
guarantor, their successors, assigns, heirs and personal representatives;
provided, however, the rights and obligations of the BORROWER are not
assignable, delegable or transferable without the consent of the

                                       17

<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

BANK. All of the rights of the BANK under this Agreement and the Loan Documents
shall inure to the benefit of any participating BANK or BANKS and its or their
successors and assigns.

J. Expenses; Proceeds of Collateral. The BORROWER covenants and agrees that it
shall pay to the BANK, on demand, any and all reasonable out-of-pocket expenses,
including reasonable attorneys' fees, court costs, sheriffs' fees, and other
expenses incurred or paid by the BANK in protecting and enforcing its rights
under this Agreement, the Loan Documents, and the other Obligations, including
the costs of preparation of any amendments, modifications, consents, or waivers
in respect of the Loan Agreements or the Loan Documents, and all filing,
auditing, accounting, and appraisal fees. After deducting all of said expenses
and the reasonable expenses of retaking, holding, preparing for sale, selling
and the like, the residue of any proceeds of collections or sale of Collateral
shall be applied to the payment of principal of or interest on Obligations of
the BORROWER to the BANK in such order or preference as the BANK may determine,
and any excess shall be returned to the BORROWER (subject to the provisions of
the Uniform Commercial Code) and the BORROWER shall remain liable for any
deficiency.

K.  The BANK's Right of Offset.  The BORROWER hereby grants to the BANK a
continuing security interest in, and upon an Event of Default the right to set
off against, any deposits or other sums at any time credited or due from the
BANK or Citizens Bank Investment Services, Inc. to the BORROWER, and any
securities or other property of the BORROWER which at any time are in the
possession of the BANK or Citizens Bank Investment Services, Inc., for the
payment of any Obligations due the BANK. The BANK may apply or set off such
deposits or other sums against the BORROWER's Obligations whether or not the
Collateral is considered by the BANK to be adequate. The BORROWER expressly
grants to the BANK the right to set off and apply such deposits and sums upon an
Event of Default without having to resort to recourse to any other Collateral in
which the BANK has a security interest.

L. Notices. All notices, requests, demands and other communications provided for
hereunder shall be in writing (including telegraphic communication) and shall be
either mailed by certified mail, return receipt requested, or delivered by
overnight courier service, to the applicable party at the addresses set forth in
this Agreement.

M. Savings Clause. Any provision of this Agreement or any of the Loan Documents
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or thereof
or affecting the validity or enforceability of such provision in any other
jurisdiction.

N. Term of this Agreement and the Loan Documents. This Agreement and the Loan
Documents shall remain in full force and effect until all of the Obligations
have been paid in

                                       18

<PAGE>


Citizens Bank NH/Presstek, Inc. Loan Agreement

full, all of the terms, conditions and covenants under the Loan Documents have
been performed, and all commitments of the BANK to advance funds under the Loan
has terminated.

O. Interest Rate Provisions. The interest rate provisions of each of the
Obligations are subject to the condition that in no event shall the amount paid
or agreed to be paid to the holder of such Obligation which is deemed interest
under applicable law exceed the maximum rate of interest on the unpaid principal
balance of such Obligation allowed by applicable law, if any, (the "Maximum
Allowable Rate"). For purposes hereof, "applicable law" shall mean the law in
effect on the date hereof, except that if there is a change in such law which
results in a higher Maximum Allowable Rate being applicable to the Obligation
subject thereto, then such Obligation shall be governed by such amended law from
and after its effective date. In the event that fulfillment of any provisions of
any Obligation results in the interest rate thereunder being in excess of the
Maximum Allowable Rate, then amount to be paid thereunder resulting in an
excessive interest rate shall automatically be reduced to eliminate such excess.
If notwithstanding the foregoing, the holder of such Obligation receives an
amount which under applicable law would cause the interest rate thereunder to
exceed the Maximum Allowable Rate, the portion thereof which would be excessive
shall automatically be applied to and deemed a prepayment of the unpaid
principal balance under such Obligation and not a payment of interest.

P. Proposed Mortgage Term Loan. Upon the BORROWER's completion of the
construction of its proposed new facility in Hudson, New Hampshire, and issuance
of occupancy and operating permits therefor by the appropriate authorities, the
BANK agrees to use its best efforts to provide to the BORROWER a mortgage term
loan in an approximate amount of up to $6,000,000.00 and for a term not to
exceed fifteen (15) years. The actual amount, term, applicable interest rate and
other charges will be subject to agreement of the BANK and the BORROWER at the
time of the underwriting of the mortgage term loan. The proceeds of such
mortgage term loan will be used to pay outstanding principal under the Revolving
Line of Credit Loan but shall not reduce the maximum available amount thereunder
as provided by Section I. A. of this Agreement. The mortgage term loan will be
secured by a first mortgage on the completed facility and real estate. Whether
the BANK will be able to provide such a mortgage term loan will depend upon the
then general banking conditions and underwriting requirements. It will also
depend upon conditions specific to the BORROWER and the property, such as the
financial and operating condition of the BORROWER, the appraised value and
environmental condition of the property, and other specific underwriting
criteria applicable to the BORROWER. While the BANK will use its best efforts to
make this mortgage term loan available, the BANK cannot guaranty that it will be
able to do so.

Q. Waiver of Jury Trial. THE BORROWER WAIVES ANY RIGHTS IT MAY HAVE TO A TRIAL
BY JURY OF ANY DISPUTE ARISING UNDER OR RELATING TO THIS AGREEMENT OR ANY OF THE
LOAN DOCUMENTS, AND AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE
SITTING WITHOUT A JURY.
