Item 2. Acquisition or Disposition of Assets.

                  On February 15, 1996, Presstek, Inc. (the "Company") acquired
90% of the outstanding common stock (the "Purchased Shares") of Catalina
Coatings, Inc., an Arizona corporation ("Catalina"). Catalina is engaged in the
development, manufacture and sale of vacuum deposition coating equipment and the
licensing and sublicensing of patent rights with respect to vapor deposition
process to coat moving webs of material at high rates. The Company intends to
continue the business of Catalina which will operate as a subsidiary of the
Company. The Purchased Shares were acquired from David G. Shaw ("Shaw"), Marc G.
Langlois ("Langlois"), and David G. Shaw and Lynn R. Shaw, as trustees of the
David and Lynn Shaw Charitable Remainder Unitrust, dated February 12, 1996
(collectively, the "Selling Shareholders"), pursuant to a Stock Purchase
Agreement (the "Stock Purchase Agreement") dated and effective as of January 1,
1996 by and among the Company, the Selling Shareholders and John E. Madocks
("Madocks") and Catalina. The aggregate consideration paid by the Company
pursuant to the Stock Purchase Agreement was $8,400,000, of which $8,200,000
represented the purchase price of the Purchased Shares and $200,000 represented
consideration for the non-competition and confidentiality covenants of Shaw and
Langlois.

         Simultaneous with the closing of the acquisition (the "Closing"), the
Company, Catalina, Shaw, Langlois and Madocks entered into a Put and Call Option
Agreement (the "Option Agreement") which provides the Company with the right, at
any time after February 15, 2000, to acquire the remaining 10% of the
outstanding common stock of Catalina (the "Remaining Shares") from Shaw,
Langlois and Madocks for aggregate consideration of $2,000,000. The Option
Agreement also provides Shaw, Langlois and Madocks with the right, at any time
after August 15, 2000, to cause the Company to purchase the Remaining Shares for
aggregate consideration of $1,000,000. The Option Agreement will terminate if
Catalina consummates an initial public offering of its securities prior to
February 15, 2000.

          Simultaneous with the Closing: (i) Catalina entered into employment
agreements with each of Shaw and Langlois which provide for their employment as
President and Technical Director, and Vice-President of Engineering,
respectively, of Catalina for a four-year employment term; (ii) Messrs. Shaw,
Langlois and Madocks entered into confidentiality and non-competition agreements
with the Company and Catalina, (iii) the Company granted Messrs Shaw, Langlois
and Madocks five-year non-qualified options to purchase 47,500, 47,500 and 5,000
shares, respectively, of the Company's common stock at an exercise price of
$89.50 per share and (iv) Catalina granted to Messrs. Shaw, Langlois and Madocks
an option to purchase 2.375%, 2.375% and .250%, respectively, of the issued and
outstanding common stock of Catalina in the event that a registration statement

relating to an initial public offering of Catalina common stock is declared
effective by the Securities and Exchange Commission not later than 5:00 Eastern
Standard Time on February 15, 2000.

         The source of the consideration paid for the Purchased Shares as well
as the non-competition and confidentaility covenants of Shaw and Langlois was a
private placement of common stock of the Company.

         The consideration paid by the Company for the Purchased Shares was
determined by negotiations with the Selling Shareholders and their
representatives.

         The descriptions of the Stock Purchase Agreement and the other
agreements described herein, are qualified in their entirety by reference to the
copy of the Stock Purchase Agreement and the other agreements filed as exhibits

sale of the Purchase Shares. Any such request must be delivered to the Selling

                                       -7-


<PAGE>



Shareholders in writing not later than 120 days following the Closing Date. If
the Section 338(h)(10) Election is made, the parties by joint written agreement
will allocate the "aggregate deemed sales price" as computed under Section 338
of the Code and the Treasury Regulations promulgated thereunder (and/or similar
state, or local, tax law provision) among Catalina's assets for income tax
purposes based on an appraisal to be obtained by the Buyer at the expense of the
Buyer.

                  (b) the Selling Shareholders shall prepare and file all local,
state, foreign and/or federal taxes with respect to the tax periods of Catalina
ending on or prior the Closing Date. The Effective Date shall be the date of
termination of Catalina's Subchapter S tax election. The Selling Shareholders

for such periods (including the income, gains and losses (if any) recognized by
virtue of the Section 338(h)(10) Election and deferred revenue on contracts of
approximately $2,126,000). Catalina shall be responsible for all local, state,
foreign and/or federal taxes reflected on returns for the tax period beginning
on the Effective Date of this Agreement.

         4. Representations and Warranties By Catalina and by the Selling
Shareholders as to Catalina. Catalina and the Selling Shareholders hereby
jointly and severally represent and warrant to the Buyer as follows:

                                       -8-


<PAGE>



            4.1. Organization, Standing and Power. Catalina is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Arizona, with full corporate power and authority and all necessary
consents, licenses and permits, to own, lease, license and operate its
properties and assets and to carry on Catalina's business as currently conducted
by it; provided, however, that with respect to Intellectual Property, as defined
in Section 4.12 of this Agreement, the representations and warranties set forth
in Section 4.12 shall prevail over those set forth in this section 4.1. Neither
the character and location of any of Catalina's properties owned or leased by
Catalina, nor the conduct of its business, makes it necessary for it to qualify
to do business as a foreign corporation in any state. True and correct copies of
the Articles of Incorporation of Catalina and all amendments thereto, and of the
By-laws of Catalina, as amended to date, have been furnished to the Buyer and
are complete and correct. Catalina's minute books contain complete and accurate
records of all meetings and other corporate actions of Catalina's stockholders
and/or its Board of Directors.

            4.2. Capitalization. The authorized capital stock of Catalina
consists of 1,000,000 shares of Common Stock, $1.00 par value per share, of
which 12,500 shares are issued and outstanding at the date hereof, and 987,500

                                       -9-


<PAGE>



shares are authorized and unissued at the date hereof. All of the issued and
outstanding shares of Common Stock have been duly and validly authorized and
issued and are fully paid and nonassessable, have not been issued and are not
owned or held in violation of any preemptive or similar right of any person and
are owned of record and beneficially solely by the Selling Shareholders, free
and clear of all Liens, stockholders agreements or voting trusts. There is no
commitment, plan, or arrangement to issue, and no outstanding option, warrant,
or other right calling for the issuance of, any share of capital stock of
Catalina or any security or other instrument convertible into, exercisable to
purchase, or exchangeable for, capital stock of Catalina. There is no personal
liability, and there are no preemptive or similar rights, attached to Catalina's
Common Stock.

            4.3. Interests in Other Entities. Except as described on Schedule
4.3 hereof, Catalina does not (A) own, directly or indirectly, of record or
beneficially, any shares of voting stock or other equity securities of any other
corporation, (B) have any ownership interest, direct or indirect, of record or
beneficially, in any unincorporated entity, or (C) have any obligation, direct
or indirect, present or contingent, (1) to purchase or subscribe for any

                                      -10-


<PAGE>



interest in, advance or loan monies to, or in any way make investments in, any
person or entity, or (2) to share any profits or capital investments or both.

            4.4. Financial Statements. Set forth as Schedule 4.4 hereof are true
and correct copies of Catalina's unaudited balance sheet as at December 31, 1995
and the related unaudited statement of operations for the period ended December
31, 1995 (the "Unaudited 1995 Financials"). The Unaudited 1995 Financials were
prepared in accordance with generally accepted accounting principles
consistently applied, are in accordance with the books and records of Catalina,
and are correct and complete in all respects, and fairly present the financial
position and results of operations and changes in financial position of Catalina
as at the period ended December 31, 1995, including (a) royalties and all
revenues received from the exploitation of any of its assets (including without
limitation, patent licenses) and provisions amounting to one percent (1%) of
machinery sales prices for any liabilities arising by reason of warranties given
on machinery manufactured by Catalina or product liability exposure, with
respect to such machinery. Catalina has accounted for and paid royalties to
patent licensors at the date of the 1995 Financials in accordance with the terms
of the agreements of Catalina with such persons; and Catalina has accrued all

                                      -11-


<PAGE>



unpaid amounts to become due in respect of all sales activity to the date of the
1995 Financials.

            4.5. Tax Matters.

                  (a) Catalina has, in accordance with all applicable laws,
rules and regulations, filed with the appropriate governmental agencies and has
delivered or made available to the Buyer complete and accurate copies of all
federal, state, local and foreign tax returns, statements, reports, estimates,
declarations, elections, and forms (hereinafter collectively called "Tax
Returns") required to be filed by it or obtained the necessary extensions
(copies of all of which it has delivered or made or will make available prior to
the Closing to the Buyer), and has paid in full or made adequate provision for
the payment of all taxes, interest, penalties, assessments and deficiencies
shown to be due or claimed to be due on the Tax Returns. The provisions for
income and other taxes and any interest, penalties, assessments thereon and
deficiencies thereof reflected on the Balance Sheet are adequate for all accrued
and unpaid taxes of Catalina as of December 31, 1995, whether (A) incurred in
respect of or measured by income of Catalina for any periods prior to the close
of business on that date, or (B) arising out of transactions entered into, or
any state of facts existing, on or prior to that date. The provision for income
and other taxes reflected on the books of account of Catalina is adequate for

                                      -12-


<PAGE>



all income and other taxes of Catalina which accrued after December 31, 1995.
Catalina has not executed or filed with any taxing authority any agreement
extending the period for the assessment or collection of any income or other
taxes, and it is not a party to any pending or, to the best of the Selling
Shareholders' or Catalina's knowledge, threatened, action or proceeding by any
governmental authority for the assessment or collection of any income or other
taxes. The tax returns of Catalina have never been examined by the Internal
Revenue Service or any other taxing authority. Catalina has never made an
election under Section 341(f) of the Code.

                  (b) Except as set forth on Schedule 4.5(b), Catalina (i) has
not agreed to or been required to make any adjustment pursuant to Section 481(a)
of the Code, (ii) has no knowledge that the Internal Revenue Service or any
other taxing authority has proposed any such adjustment or change in accounting
method, and (iii) has no application pending with a Governmental Authority
requesting permission for any change in accounting method.

                  (c) Valid and effective state and federal elections to be
treated as an "S" corporation were duly made and are in effect for all taxable
years from 1991 through the Closing Date.

                                      -13-


<PAGE>




            4.6. Absence of Undisclosed Liabilities. Except as set forth on
Schedule 4.6 hereof, Catalina has no material liabilities or obligations of any
nature whatsoever, whether accrued, absolute, contingent or otherwise, except
(i) in the case of liabilities, obligations and contingencies of a type
customarily reflected on a corporate balance sheet prepared in accordance with
generally accepted accounting principles, as set forth on the Unaudited 1995
Balance Sheet or (ii) in the case of other types of liabilities and obligations,
as described in any of the Schedules delivered pursuant hereto or omitted from
such Schedules in accordance with the terms of this Agreement, or (iii) normally
recurring liabilities incurred, consistent with past practice, in the ordinary
course of business since December 31, 1995 (in the case of liabilities,
obligations and contingencies of the type referred to in clause (i) above). To
the extent that the foregoing representations apply to product liability claims
in the nature of personal injury or wrongful death, then such representation is
limited to Selling Shareholders' and Catalina's best knowledge.

            4.7. Properties. Catalina is the owner of and has good and
marketable title to all properties and assets reflected as owned on the 1995

                                      -14-


<PAGE>



Balance Sheet free and clear of all Liens, except as described on Schedule 4.7
hereof. To the best knowledge of the Selling Shareholders and/or Catalina, (i)
all plants, structures, machinery and equipment which are material to the
business, operation or condition (financial or otherwise) of Catalina are in
good and usable operating condition and repair, and are suitable for the
purposes for which they are used; and none of such plants, structures, machinery
or equipment are in need of maintenance or repairs except for ordinary, routine
maintenance and repairs which are not substantial in nature or cost, and (ii)
all properties and assets (including Intellectual Property as defined in Section
4.12 herein) owned by Catalina or leased or licensed by Catalina from a third
party constitute all such properties and assets which are necessary to the
business of Catalina as currently conducted. Schedule 4.7 also contains an
accurate and complete list setting forth all (A) real property leases executed
by or binding on Catalina as lessee, sub-lessee, sub-lessor, tenant or assignee
(the "Leased Premises"), and (B) machinery and equipment, motor vehicles and
other significant personal property and assets owned by Catalina or leased or
licensed by or to Catalina, or which is otherwise used or available for use in
connection with the business of Catalina; correct and complete copies of any

                                      -15-


<PAGE>



lease and licenses and the terms of any oral agreements are described on
Schedule 4.7, together with all amendments thereto. Catalina enjoys peaceful and
undisturbed possession as to its real properties and under all leases and
licenses under which it is operating.

         All water, utility and other charges, sewer rent and assessments
affecting its real properties, the Leased Premises or any part thereof, and all
taxes imposed against or affecting the Leased Premises (to the extent payable by
Catalina) or any part thereof, have been paid in full, accrued or reflected on
the 1995 Balance Sheet. Neither Catalina nor either of the Selling Shareholders
has received notice of any assessments, nor has knowledge of any pending
assessments, affecting its real properties and the Leased Premises (to the
extent payable by Catalina). To the best knowledge of the Selling Shareholders
and Catalina, Catalina's use of its real properties and the Leased Premises
conforms in all material respects with all covenants and restrictions and all
applicable building, zoning, land use and other laws.

            4.8. Accounts Receivable; Inventories. All accounts and notes
receivable that (a) are reflected on the 1995 Balance Sheet, or (b) that arose
since the date thereof, are good and collectible and arose in the ordinary
course of business for goods sold and invoiced or services performed, and are

                                      -16-


<PAGE>


owned by Catalina free and clear of all Liens, in each case, at the aggregate
recorded amounts thereof, less the amount of the allowance for doubtful accounts
as reflected on the 1995 Balance Sheet and to the best knowledge of the Selling
Shareholders and Catalina are without right of recourse, defense, deduction,
counterclaim, offset, or set off on the part of the obligor. To the best
knowledge of the Selling Shareholders and Catalina, there is no matter which
would affect the collectability of any receivables to an extent greater than
that reserved against in a manner consistent with Catalina's past practices. The
inventories reflected on the 1995 Balance Sheet and thereafter added consist of
items acquired in the ordinary course of business, in customary quantities and
at prevailing prices, and are of a quality and quantity usable or saleable in
the ordinary course of business as conducted by Catalina, except for obsolete
materials, slow-moving items, materials of below standard quality and not
readily marketable items, all of which have been written down to net realizable
value or adequately reserved against on the books and records of Catalina. All
inventories are stated at the lower of cost or market in accordance with
generally accepted accounting principles.

            4.9. Absence of Changes. Except as set forth on Schedule 4.9 hereof,
since December 31, 1995, there has not been (i) any material adverse

                                      -17-


<PAGE>



change in the condition (financial or otherwise), assets, liabilities, business,
prospects, or results of operations of Catalina (including, without limitation,
any such adverse change resulting from damage, destruction or other casualty
loss, whether or not covered by insurance), (ii) any waiver by Catalina of any
right, or cancellation of any debt or claim, of substantial value, (iii) any
declaration, setting aside or payment of any dividend or other distribution or
payment in respect of the capital stock of Catalina (except distributions to the
Selling Shareholders with respect to payment of income tax obligations as set
forth on Schedule 4.9(a) hereof), or any direct or indirect redemption,
purchase, or other acquisition of any capital stock of Catalina, (iv) any change
in any of the arrangements that are referred to in section 4.15 hereof or any
transactions of the type that are referred to in clause (F) of section 4.17
hereof, or (v) any change in the accounting principles or methods that are
utilized by Catalina. In addition, except as set forth on Schedule 4.9 hereto
(which describes, inter alia, the stock option of Messrs. Langlois and Madocks),
since December 31, 1995 Catalina has not:

                  (a) issued any stock, bonds or other corporate securities;

                                      -18-


<PAGE>




                  (b) discharged or satisfied any Lien, or incurred or paid any
liabilities, absolute or contingent, other than in the ordinary course of
business;

                  (c) mortgaged or pledged or subjected to Lien, any of its
material assets, tangible or intangible;

                  (d) sold, transferred or disposed of any of its assets except

proceeding has been initiated prior to the end of the relevant limitation
period, the representations and warranties made by the Selling Shareholders with
respect to such item shall survive until the conclusion of such audit or other

<PAGE>



representations and warranties contained in Sections 4.1, 4.2, 5.2, 5.3 and 5.4
(all of which pertain to the organization, capitalization and ownership of

Shareholders to transfer the shares of Common Stock to the Buyer) shall survive

event that any proceeding with respect to any such matter has been initiated
prior to the end of the relevant limitation period, the representations and
warranties made by the Selling Shareholders with respect to such matter shall
survive until the conclusion of such proceeding).

         8. Indemnification.

            8.1. Indemnification by the Selling Shareholders. Subject to the
limitation periods set forth in Article 7 hereof and the limitations on
liability and the other rights of the Selling Shareholders set forth in this
Article 8, each Selling Shareholder and Catalina jointly and severally hereby
indemnify the Buyer and hold it harmless at all times from and after the date
hereof against and in respect of:

                  (a) Any and all damages, losses, liabilities, taxes and
deficiencies and penalties and interest thereon and costs and expenses to the
Buyer and/or to Catalina ("Losses") up to but not in excess of the Purchase
Price resulting from any misrepresentation, breach of warranty or nonfulfillment

                                      -42-


<PAGE>



of any covenant or agreement on the part of the Selling Shareholder or Catalina
under this Agreement;

                  (b) Any claims or litigation relating to Catalina now pending
or threatened or which may hereafter be brought against Buyer and/or Catalina
based upon events occurring prior to the date hereof and not attributable to the
acts of the Buyer, including but not limited to any claims arising by reason of
any non-payment of royalties determined to be due in respect of sales activity
prior to the date hereof upon audit of the relevant books and records of
Catalina by any royalty payee;

                  (c) Any and all actions, suits, proceedings, claims, demands,
assessments, judgments, costs, losses, liabilities and reasonable legal and
other expenses incident to any of the foregoing.

             8.2. Indemnification by the Buyer. Subject to the limitation
periods set forth in Article 7 hereof and the limitations on liability and the
other rights of the Buyer set forth in this Article 8, the Buyer hereby
indemnifies the Selling Shareholders and holds them harmless at all times from
and after the date hereof against and in respect of:

                  (a) Any and all Losses resulting from any misrepresentation,
breach of warranty, nonfulfillment of any covenant or agreement on the part of
the Buyer under this Agreement;

                                      -43-


<PAGE>



                  (b) Any claim relating to Catalina that may hereafter be
commenced against them personally that is based upon events that occur
subsequent to the Closing Date; and

                  (c) Any and all actions, suits, proceedings, claims, demands,
assessments, judgments, costs, losses, liabilities and reasonable legal and
other expenses incident to any of the foregoing.

             8.3. Notice to the Indemnitor. For the purposes of this Section,
any person entitled to indemnification shall be known as an "Indemnified Party"
and any person liable to indemnify an Indemnified Party shall be known as the
"Indemnitor". Promptly after the assertion of any claim by a third party or
occurrence of any event that may give rise to a claim for indemnification from
the Indemnitor under this Article ("Asserted Liability"), the Indemnified Party
shall notify the Indemnitor in writing of such Asserted Liability, and with
respect to claims by third parties, advise the Indemnitor whether the
Indemnified Party intends to assume control of the defense of such claim. Any
failure to so notify the Indemnitor shall not relieve it from any liability that
it may have to the Indemnified Party under this Article 8, except to the extent

                                      -44-


<PAGE>



that such failure to notify shall be prejudicial to a proper defense against the
claim or action or other satisfactory resolution thereof.

             8.4. Rights of Parties to Defend. If the Indemnified Party
determines to assume control of the defense of such claim in accordance with the
provisions of paragraph 8.3, the Indemnitor shall have the right to be
represented, at its own expense by its own counsel and accountants, their
participation to be subject to the reasonable direction of the Indemnified
Party. If the Indemnified Party does not assume control of the defense of any
claim of a third party by written notice given simultaneously with the notice
required under Section 9.3 hereof, the Indemnitor shall have the right, at its
own expense, to assume control of the defense of and defend against such claim.
In either case, the Indemnified Party shall make available to the Indemnitor and
its attorneys and accountants, at all reasonable times during normal business
hours, all books, records, and other documents in its possession relating to
such claim. The party assuming control of the defense of any such claim shall be
furnished all reasonable assistance in connection therewith by the other party.

                                      -45-


<PAGE>



             8.5. Settlement.

                  (a) To the extent that the settlement of a claim, the defense
of which has been assumed by the Indemnitor, involves the payment of money only,
the Indemnitor shall have the right, in consultation with the Indemnified Party,
to settle those aspects dealing only with the payment of money, provided that
the Indemnitor pays such money and such settlement includes a general release
from the other parties to such proceeding in favor of the Indemnified Party.
Notwithstanding the foregoing, in connection with any such defense or
settlement, the Indemnitor shall not enter into a consent decree involving
injunctive or other non-monetary relief or consent to an injunction without the
Indemnified Party's prior written consent.

                  (b) In the event that the Indemnified Party desires to settle
any third party claim (whether or not contested by the Indemnitor), the
Indemnified Party shall advise the Indemnitor in writing of the amount it
proposes to pay in settlement thereof (the "Proposed Settlement"). If such
Proposed Settlement is unsatisfactory to the Indemnitor, it shall have the
right, at its expense, to continue to defend the claim or to assume control of
the defense of such claim from the Indemnified Party, as the case may be, by
giving written notice of such election to the Indemnified Party within ten (10)
business days after the Indemnitor's receipt of the advice of the Proposed

                                      -46-


<PAGE>



Settlement. If the Indemnitor does not deliver such written notice within ten
(10) business days after receipt of such advice, the Indemnified Party may offer
the Proposed Settlement to the third party making such claim. If the Proposed
Settlement is not accepted by the party making such claim, any new Proposed
Settlement figure that the Indemnified Party may wish to present to the party
making such claim shall first be presented to the Indemnitor which shall have
the right, subject to the conditions hereinabove set forth in this Section, to
assume control of the defense of such claim. With respect to the handling of all
settlement proposals as set forth in this Section 9.5, the Indemnitor shall
indemnify the Indemnified Party and hold it harmless against and from any and
all costs of defense, payment or settlement, including reasonable attorneys'
fees, incurred in connection therewith.

            8.6. Reimbursement. At the time that the Indemnified Party shall
suffer a loss because of a breach of warranty, representation or covenant by the
Indemnitor or at the time the amount of any liability on the part of the
Indemnitor under this Section is determined (which in the case of payments to
third persons shall be the earlier of (i) the date of such payments or (ii) the
date that a court of competent jurisdiction shall enter a final judgment, order

                                      -47-


<PAGE>



or decree (after exhaustion of appeal rights establishing such liability)), the
Indemnitor shall forthwith, upon notice from the Indemnified Party, pay to the
Indemnified Party the amount of the indemnity claim. If such amount is not paid
forthwith, then the Indemnified Party may, at its option, take legal action
against the Indemnitor for reimbursement in the amount of its indemnity claim.
For purposes hereof the indemnity claim shall include the amounts so paid (or
determined to be owing) by the Indemnified Party together with costs and
reasonable attorney's fees and interest on the foregoing items at the rate of
10% per annum from the date the indemnity claim is due from the Indemnified
Party to the Indemnitor, as hereinabove provided, until the indemnity claim
shall be paid.

            8.7. Tax Indemnification. In accordance with the indemnification
obligations of Selling Shareholders set forth elsewhere in this Article 8, the
Selling Shareholders shall be liable for, shall pay and shall indemnify and hold
the Buyer and Catalina harmless against taxes, interest, penalties, assessments
and deficiencies of Catalina for any taxable year or taxable period ending on or
before the date hereof due or payable with respect to the operations, assets or
business of Catalina on or before the date hereof, including any taxes,
interest, penalties, assessments and deficiencies resulting

                                      -48-


<PAGE>



from making the Section 338(h)(10) Election and any liability for taxes,
interest, penalties, assessments and deficiencies pursuant to Treasury
Regulation ss.1.1502-6.

<PAGE>



                  WHEREAS, unless otherwise indicated, capitalized terms herein
shall have the same meaning as used in the Stock Purchase Agreement.

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants herein contained, the parties hereto agree as follows:

                  1. As used in this Agreement, the term "Confidential
Information" shall mean any and all information (oral and written) relating to
Catalina or to the Buyer or to their respective properties, assets, operations
or business, other than such information which can be shown by Shaw to be in the
public domain (such information not being deemed to be in the public domain
merely because it is embraced by more general information which is in the public
domain) other than as the result of a breach of the provisions of Section 2
below, including, but not limited to, information relating to: their prospective
products, processes, strategic plans and proposals, know how, prospects,
financial condition and condition of the operations or marketing plans of
Catalina and/or the Buyer.

                  2. In consideration of $100,000.00, receipt of which is hereby
acknowledged, Shaw hereby agrees to not, at any time, directly or indirectly,
use, communicate, disclose or disseminate any Confidential Information in any
manner whatsoever.

                  3. In consideration of $100,000.00, receipt of which is hereby

                                       -2-

directly or indirectly (A) engage or become interested in any business (whether
as owner, manager, operator, licensor, licensee, lender, partner, stockholder,
joint venturer, director, officer, employee, consultant, partner, agent,
independent contractor, or otherwise) that is competitive with the business of
Catalina as of the date hereof at any time during his employment, or (B) take
any other action that constitutes an interference with or a disruption of the
Buyer's operation of the business of Catalina or the Buyer or the Buyer's use,
ownership and enjoyment of the assets and properties of Catalina throughout the
continental United States. Notwithstanding the foregoing, nothing shall prohibit
Shaw from acquiring and holding up to two percent (2%) of the publicly traded
equity securities of a business that competes with Catalina or the Buyer.

                  4. For purposes of clarification, but not of limitation, Shaw
hereby acknowledges and agrees that the provisions of Section 3 above shall
serve as a prohibition against him during the period described therein, directly
or indirectly, hiring, offering to hire, enticing away or in any other manner
persuading or attempting to persuade any officer, employee, agent, consultant,
lessor, lessee, licensor, licensee, customer, prospective customer or supplier
of Catalina to discontinue or alter his or its relationship with Catalina.

                  5. The parties hereto hereby acknowledge and agree that (i)
the Buyer and Catalina would be irreparably injured in the event of a breach by

                                       -3-


<PAGE>



Shaw of any of his obligations under this Agreement, (ii) monetary damages would
not be an adequate remedy for any such breach, and (iii) the Buyer and Catalina
shall be entitled to injunctive relief, in addition to any other remedy that
they may have, in the event of any such breach. If any restriction contained in
this Agreement shall be deemed to be invalid, illegal or unenforceable by reason
of the extent, duration, or geographical scope thereof, or otherwise, then the
court making such determination shall have the right to reduce such extent,
duration, geographical scope, or other provisions hereof, and in its reduced
form such restriction shall then be enforceable in the manner contemplated
hereby.

                  6. This Agreement may only be amended by a written instrument
executed by each of the parties hereto.

                  7. This Agreement constitutes the entire agreement of the
parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings of the parties, oral and written, with
respect to the subject matter hereof.

                  8. This Agreement shall be governed by the laws of the State
of New Hampshire applicable to contracts made and to be wholly performed
therein, without giving effect to principles of conflicts of laws.

                  9. This Agreement shall inure to the benefit of, and shall be
binding upon, the parties hereto and their respective heirs, legal
representatives, successors and permitted assigns. Nothing herein contained,
express or implied, is intended to confer upon any person other than the parties

                                       -4-


<PAGE>



hereto and their respective heirs, legal representatives, successors and
permitted assigns, any rights or remedies under or by reason of this Agreement.

                  10. The failure of any of the parties hereto to at any time
enforce any of the provisions of this Agreement shall not be deemed or construed
to be a waiver of any such provision, nor to in any way affect the validity of
this Agreement or any provision hereof or the right of either of the parties
hereto to thereafter enforce each and every provision of this Agreement. No
waiver of any breach of any of the provisions of this Agreement shall be
effective unless set forth in a written instrument executed by the party or
parties against whom or which enforcement of such waiver is sought; and no
waiver of any such breach shall be construed or deemed to be a waiver of any
other or subsequent breach.

                  11. If any provision of this Agreement is held or declared
invalid or unenforceable for any reason by any court of competent jurisdiction,
such provision shall be modified by such court to the extent necessary to make
the provision valid and operative, or if it cannot be so modified, then the
provision shall be severed, and the remainder of the Agreement shall continue in
full force and effect as if the Agreement has been signed with the invalid
portion so modified or eliminated but shall not affect any other provision of
this Agreement.

                  12. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given or

                  WHEREAS, the Buyer, David G. Shaw, Langlois, John E. Madocks
and David G. Shaw and Lynn R. Shaw, as Trustees of the David and Lynn Shaw

required to enter into covenants of confidentiality and non-competition with

                  WHEREAS, Catalina has entered into separate employment
agreements (separately, the "Employment Agreement") with each of Messrs.
Langlois and Shaw pursuant to which they are required to enter covenants of
confidentially and non-competition with Catalina; and

                  WHEREAS, the covenants of Langlois set forth in this Agreement
are intended to be the covenants so required under the Stock Purchase Agreement
and the Employment Agreement; and


<PAGE>



                  WHEREAS, unless otherwise indicated, capitalized terms herein
shall have the same meaning as used in the Stock Purchase Agreement.

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants herein contained, the parties hereto agree as follows:

                  1. As used in this Agreement, the term "Confidential
Information" shall mean any and all information (oral and written) relating to
Catalina or to the Buyer or to their respective properties, assets, operations
or business, other than such information which can be shown by Langlois to be in
the public domain (such information not being deemed to be in the public domain
merely because it is embraced by more general information which is in the public
domain) other than as the result of a breach of the provisions of Section 2
below, including, but not limited to, information relating to: their prospective
products, processes, strategic plans and proposals, know how, prospects,
financial condition and condition of the operations or marketing plans of
Catalina and/or the Buyer.

                  2. In consideration of $100,000.00, receipt of which is hereby
acknowledged, Langlois hereby agrees to not, at any time, directly or
indirectly, use, communicate, disclose or disseminate any Confidential
Information in any manner whatsoever.

                  3. In consideration of $100,000.00, receipt of which is hereby
acknowledged, Langlois hereby agrees to not, during the term of his employment

                                       -2-


<PAGE>



pursuant to the Employment Agreement and for a period of two years thereafter
(but in no event for less than a four-year period commencing the date hereof),
directly or indirectly (A) engage or become interested in any business (whether
as owner, manager, operator, licensor, licensee, lender, partner, stockholder,
joint venturer, director, officer, employee, consultant, partner, agent,
independent contractor, or otherwise) that is competitive with the business of
Catalina as of the date hereof at any time during his employment, or (B) take
any other action that constitutes an interference with or a disruption of the
Buyer's operation of the business of Catalina or the Buyer or the Buyer's use,
ownership and enjoyment of the assets and properties of Catalina throughout the
continental United States. Notwithstanding the foregoing, nothing shall prohibit
Langlois from acquiring and holding up to two percent (2%) of the publicly
traded equity securities of a business that competes with Catalina or the Buyer.

                  4. For purposes of clarification, but not of limitation,
Langlois hereby acknowledges and agrees that the provisions of Section 3 above
shall serve as a prohibition against him during the period described therein,
directly or indirectly, hiring, offering to hire, enticing away or in any other
manner persuading or attempting to persuade any officer, employee, agent,
consultant, lessor, lessee, licensor, licensee, customer, prospective customer
or supplier of Catalina to discontinue or alter his or its relationship with
Catalina.

                  5. The parties hereto hereby acknowledge and agree that (i)
the Buyer and Catalina would be irreparably injured in the event of a breach by

                                       -3-


<PAGE>



Langlois of any of his obligations under this Agreement, (ii) monetary damages
would not be an adequate remedy for any such breach, and (iii) the Buyer and
Catalina shall be entitled to injunctive relief, in addition to any other remedy
that they may have, in the event of any such breach. If any restriction
contained in this Agreement shall be deemed to be invalid, illegal or
unenforceable by reason of the extent, duration, or geographical scope thereof,
or otherwise, then the court making such determination shall have the right to
reduce such extent, duration, geographical scope, or other provisions hereof,
and in its reduced form such restriction shall then be enforceable in the manner
contemplated hereby.

                  6. This Agreement may only be amended by a written instrument
executed by each of the parties hereto.

                  7. This Agreement constitutes the entire agreement of the
parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings of the parties, oral and written, with
respect to the subject matter hereof.

                  8. This Agreement shall be governed by the laws of the State
of New Hampshire applicable to contracts made and to be wholly performed
therein, without giving effect to principles of conflicts of laws.

                  9. This Agreement shall inure to the benefit of, and shall be
binding upon, the parties hereto and their respective heirs, legal
representatives, successors and permitted assigns. Nothing herein contained,

                                       -4-


<PAGE>



express or implied, is intended to confer upon any person other than the parties
hereto and their respective heirs, legal representatives, successors and
permitted assigns, any rights or remedies under or by reason of this Agreement.

                  10. The failure of any of the parties hereto to at any time
enforce any of the provisions of this Agreement shall not be deemed or construed
to be a waiver of any such provision, nor to in any way affect the validity of
this Agreement or any provision hereof or the right of either of the parties
hereto to thereafter enforce each and every provision of this Agreement. No
waiver of any breach of any of the provisions of this Agreement shall be
effective unless set forth in a written instrument executed by the party or
parties against whom or which enforcement of such waiver is sought; and no
waiver of any such breach shall be construed or deemed to be a waiver of any
other or subsequent breach.

                  11. If any provision of this Agreement is held or declared
invalid or unenforceable for any reason by any court of competent jurisdiction,
such provision shall be modified by such court to the extent necessary to make
the provision valid and operative, or if it cannot be so modified, then the
provision shall be severed, and the remainder of the Agreement shall continue in
full force and effect as if the Agreement has been signed with the invalid
portion so modified or eliminated but shall not affect any other provision of
this Agreement.

                  12. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given or

                      NON-QUALIFIED STOCK OPTION AGREEMENT
                                 PRESSTEK, INC.

                  AGREEMENT made as of this 15th day of February, 1996 (the
"Grant Date") between Presstek, Inc. (the "Company"), a Delaware corporation,
having a principal place of business in Hudson, New Hampshire, and David G. Shaw
(the "Grantee") residing at 1041 E. Calle Mariposa, Tucson, Arizona 85718.

                  WHEREAS, the Company desires to grant to the Grantee an
Incentive Stock Option to purchase shares of its common stock of a par value of
$.01 a share, under and for the purposes of the 1994 Stock Option Plan of the
Company (the "Plan") pursuant to the terms thereof;

                  WHEREAS, the Company and the Grantee understand and agree that
unless otherwise defined herein any terms used herein have the same meanings as
in the Plan.

                  NOW, THEREFORE, in consideration of the mutual covenants
hereinafter set forth and for other good and valuable consideration, the parties
hereto agree as follows:

                  1. Grant of Option. The Company hereby grants to the Grantee
the right and option to purchase all or any part of an aggregate of 47,500
shares of its Common Stock, $.01 par value (the "Option Shares"), on the terms
and conditions and subject to all the limitations set forth herein and in the
Plan, which is incorporated herein by reference. The Grantee acknowledges
receipt of a copy of the Plan.


<PAGE>



                  2. Purchase Price. The purchase price of the Option Shares
covered by the Option shall be $89.50 per share.

                  3. Exercise of Option. The Option granted hereby may be
exercised cumulatively on each of the first, second, third and fourth
anniversaries of the Grant Date as to 25%, 50%, 75% and 100% of the Option
Shares, subject to the prior exercise of any portion of the Option Shares.

                  4. Term of Option. The option shall terminate five (5) years
from the date of this Agreement, but shall be subject to earlier termination as
provided herein or in the Plan.

                  If the Grantee ceases to be employed by the Company or a
subsidiary thereof for any reason other than death, Disability, termination for
cause or voluntary termination without the consent of the Company, the Option
may be exercised within thirty (30) days after the date the Grantee ceases to be
an employee, or within five (5) years from the granting of the Option, whichever
is earlier, but may not be exercised thereafter. In such event, the Option shall
be exercisable only to the extent that the right to purchase Option Shares under
the Plan has accrued and is in effect at the date of such cessation of
employment.

                  In the event the Grantee's employment is terminated by the
Company or a subsidiary thereof for "cause" (as defined in the Plan), or
voluntarily by the Grantee without the consent of the Company, the Grantee's
right to exercise any unexercised portion of this Option shall cease forthwith,
and this Option shall thereupon terminate.

                                       -2-


<PAGE>



                  In the event of Disability of the Grantee (as determined by
the Board of Directors of the Company or the 1994 Stock Option Plan Committee of
the Company, as the case may be, and as to the fact and date of which the
Grantee is notified by the Board or that Committee, as the case may be, in
writing), the Option shall be exercisable within thirty (30) days after the date
of such Disability or, if earlier, the term originally prescribed by this
Agreement. In such event, the Option shall be exercisable to the extent that the
right to purchase the Option Shares hereunder has accrued on the date the
Grantee becomes Disabled and is in effect as of such determination date.

                  In the event of the death of the Grantee while an employee of
the Company or a subsidiary thereof, within thirty days after the termination of
employment (other than termination for cause or without consent of the Company)
the Option shall be exercisable to the extent exercisable but not exercised as
of the date of death and in such event, the Option must be exercised, if at all,
within one (1) year after the date of death of the Grantee or, if earlier,
within the originally prescribed term of the Option.

                  5. Non-Assignability. The Option shall not be trans- ferable
by the Grantee otherwise than by will or by the laws of descent and distribution
and shall be exercisable, during the Grantee's lifetime, only by the Grantee.
The Option shall not be assigned, pledged or hypothecated in any way (whether by
operation of law or otherwise) and shall not be subject to execution,
attachment or similar process. Any attempted transfer, assignment, pledge,

                                       -3-


<PAGE>



hypothecation or other disposition of the Option or of any rights granted
hereunder contrary to the provisions of this Section 5, or the levy of any
attachment or similar process upon the Option or such right, shall be null and
void.

                  6. Exercise of Option and Issue of Option Shares. The Option
may be exercised in whole or in part (to the extent that it is exercisable in
accordance with its terms) by giving written notice to the Company, together
with the tender of the Option price. Such written notice shall be signed by the
person exercising the Option, shall state the number of Option Shares with
respect to which the Option is being exercised, shall contain any warranty
required by Section 7 below and shall otherwise comply with the terms and
conditions of this Agreement and the Plan. The Company shall pay all original
issue taxes with respect to the issue of the Option Shares pursuant hereto and
all other fees and expenses necessarily incurred by the Company in connection
herewith. Except as specifically set forth herein, the holder acknowledges that
any income or other taxes due from him with respect to this Option or the Option
Shares issuable pursuant to this Option shall be the responsibility of the
holder. The holder of this Option shall have rights as a shareholder only with
respect to any Option Shares covered by the Option after due exercise of the
Option and tender of the full exercise price for the Option Shares being
purchased pursuant to such exercise.

                  7. Purchase for Investment. Unless the offering and sale of
the Option Shares to be issued upon the particular exercise of the Option shall

                                       -4-


<PAGE>



have been effectively registered under the Securities Act of 1933, as now in
force or hereafter amended, or any successor legislation (the "Act"), the
Company shall be under no obligation to issue the Option Shares covered by such
exercise unless and until the following conditions have been fulfilled:

                     (a) The person(s) who exercise the Option shall warrant to
the Company, at the time of such exercise, that such person(s) are acquiring
such Option Shares for his or her own account, for investment and not with a
view to, or for sale in connection with, the distribution of any such Option
Shares, in which event the person(s) acquiring such Option Shares shall be bound
by the provisions of the following legend which shall be endorsed upon the
certificate(s) evidencing their Option Shares issued pursuant to such exercise:

                  "The shares represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended (the
                  "Act"). Such shares may not be sold, transferred or otherwise
                  disposed of unless they have first been registered under the
                  Act or, unless, in the opinion of counsel satisfactory to the
                  Company's counsel, such registration is not required."

                     (b) The Company shall have received an opinion of its
counsel that the Option Shares may be issued upon such particular exercise in
compliance with the Act without registration thereunder. Without limiting the
generality of the foregoing, the Company may delay issuance of the Option Shares
until completion of any action or obtaining of any consent, which the Company
deems necessary under any applicable law (including without limitation state
securities or "blue sky" laws).

                      NON-QUALIFIED STOCK OPTION AGREEMENT
                                 PRESSTEK, INC.

                  AGREEMENT made as of this 15th day of February, 1996 (the
"Grant Date") between Presstek, Inc. (the "Company"), a Delaware corporation,
having a principal place of business in Hudson, New Hampshire, and John E.
Madocks (the "Grantee") residing at 110 E. Yvon Drive, Tucson, Arizona 85704.

                  WHEREAS, the Company desires to grant to the Grantee an
Incentive Stock Option to purchase shares of its common stock of a par value of
$.01 a share, under and for the purposes of the 1994 Stock Option Plan of the
Company (the "Plan") pursuant to the terms thereof;

                  WHEREAS, the Company and the Grantee understand and agree that
unless otherwise defined herein any terms used herein have the same meanings as
in the Plan.

                  NOW, THEREFORE, in consideration of the mutual covenants
hereinafter set forth and for other good and valuable consideration, the parties
hereto agree as follows:

                  1. Grant of Option. The Company hereby grants to the Grantee
the right and option to purchase all or any part of an aggregate of 5,000 shares
of its Common Stock, $.01 par value (the "Option Shares"), on the terms and
conditions and subject to all the limitations set forth herein and in the Plan,
which is incorporated herein by reference. The Grantee acknowledges receipt of a
copy of the Plan.


<PAGE>



                  2. Purchase Price. The purchase price of the Option Shares
covered by the Option shall be $89.50 per share.

                  3. Exercise of Option. The Option granted hereby may be
exercised cumulatively on each of the first, second, third and fourth
anniversaries of the Grant Date as to 25%, 50%, 75% and 100% of the Option
Shares, subject to the prior exercise of any portion of the Option Shares.

                  4. Term of Option. The option shall terminate five (5) years
from the date of this Agreement, but shall be subject to earlier termination as
provided herein or in the Plan.

                  If the Grantee ceases to be employed by the Company or a
subsidiary thereof for any reason other than death, Disability, termination for
cause or voluntary termination without the consent of the Company, the Option
may be exercised within thirty (30) days after the date the Grantee ceases to be
an employee, or within five (5) years from the granting of the Option, whichever
is earlier, but may not be exercised thereafter. In such event, the Option shall
be exercisable only to the extent that the right to purchase Option Shares under
the Plan has accrued and is in effect at the date of such cessation of
employment.

                  In the event the Grantee's employment is terminated by the
Company or a subsidiary thereof for "cause" (as defined in the Plan), or
voluntarily by the Grantee without the consent of the Company, the Grantee's
right to exercise any unexercised portion of this Option shall cease forthwith,
and this Option shall thereupon terminate.

                                       -2-


<PAGE>



                  In the event of Disability of the Grantee (as determined by
the Board of Directors of the Company or the 1994 Stock Option Plan Committee of
the Company, as the case may be, and as to the fact and date of which the
Grantee is notified by the Board or that Committee, as the case may be, in
writing), the Option shall be exercisable within thirty (30) days after the date
of such Disability or, if earlier, the term originally prescribed by this
Agreement. In such event, the Option shall be exercisable to the extent that the
right to purchase the Option Shares hereunder has accrued on the date the
Grantee becomes Disabled and is in effect as of such determination date.

                  In the event of the death of the Grantee while an employee of
the Company or a subsidiary thereof, within thirty days after the termination of
employment (other than termination for cause or without consent of the Company)
the Option shall be exercisable to the extent exercisable but not exercised as
of the date of death and in such event, the Option must be exercised, if at all,
within one (1) year after the date of death of the Grantee or, if earlier,
within the originally prescribed term of the Option.

                  5. Non-Assignability. The Option shall not be transferable
by the Grantee otherwise than by will or by the laws of descent and distribution
and shall be exercisable, during the Grantee's lifetime, only by the Grantee.
The Option shall not be assigned, pledged or hypothecated in any way (whether by
operation of law or otherwise) and shall not be subject to execution,
attachment or similar process. Any attempted transfer, assignment, pledge,

                                       -3-


<PAGE>



hypothecation or other disposition of the Option or of any rights granted
hereunder contrary to the provisions of this Section 5, or the levy of any
attachment or similar process upon the Option or such right, shall be null and
void.

                  6. Exercise of Option and Issue of Option Shares. The Option
may be exercised in whole or in part (to the extent that it is exercisable in
accordance with its terms) by giving written notice to the Company, together
with the tender of the Option price. Such written notice shall be signed by the
person exercising the Option, shall state the number of Option Shares with
respect to which the Option is being exercised, shall contain any warranty
required by Section 7 below and shall otherwise comply with the terms and
conditions of this Agreement and the Plan. The Company shall pay all original
issue taxes with respect to the issue of the Option Shares pursuant hereto and
all other fees and expenses necessarily incurred by the Company in connection
herewith. Except as specifically set forth herein, the holder acknowledges that
any income or other taxes due from him with respect to this Option or the Option
Shares issuable pursuant to this Option shall be the responsibility of the
holder. The holder of this Option shall have rights as a shareholder only with
respect to any Option Shares covered by the Option after due exercise of the
Option and tender of the full exercise price for the Option Shares being
purchased pursuant to such exercise.

                  7. Purchase for Investment. Unless the offering and sale of
the Option Shares to be issued upon the particular exercise of the Option shall

                                       -4-


<PAGE>



have been effectively registered under the Securities Act of 1933, as now in
force or hereafter amended, or any successor legislation (the "Act"), the
Company shall be under no obligation to issue the Option Shares covered by such
exercise unless and until the following conditions have been fulfilled:

                     (a) The person(s) who exercise the Option shall warrant to
the Company, at the time of such exercise, that such person(s) are acquiring
such Option Shares for his or her own account, for investment and not with a
view to, or for sale in connection with, the distribution of any such Option
Shares, in which event the person(s) acquiring such Option Shares shall be bound
by the provisions of the following legend which shall be endorsed upon the
certificate(s) evidencing their Option Shares issued pursuant to such exercise:

                  "The shares represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended (the
                  "Act"). Such shares may not be sold, transferred or otherwise
                  disposed of unless they have first been registered under the
                  Act or, unless, in the opinion of counsel satisfactory to the
                  Company's counsel, such registration is not required."

                     (b) The Company shall have received an opinion of its
counsel that the Option Shares may be issued upon such particular exercise in
compliance with the Act without registration thereunder. Without limiting the
generality of the foregoing, the Company may delay issuance of the Option Shares
until completion of any action or obtaining of any consent, which the Company
deems necessary under any applicable law (including without limitation state
securities or "blue sky" laws).
