                                    ARTICLE 1

                                   THE MERGER

     In connection with the Merger, the respective boards of directors of NAC,

accordance with this Agreement and Delaware Corporate Law and the NY BCL, the
Acquired Corporation shall be merged with and into Merger Sub, the separate
corporate existence of the Acquired Corporation (except as such existence may be
continued by operation of law) shall cease, and Merger Sub shall continue as the
surviving corporation under the name OMI Communications, Inc., which name Merger
Sub shall adopt in connection with the consummation of the Merger. Merger Sub,
in its capacity as the corporation surviving the Merger, is hereinafter
sometimes referred to as the "SURVIVING CORPORATION."

     1.2 Effect of the Merger. The Surviving Corporation shall possess all the
rights, privileges, immunities and franchises of a public, as well as of a
private, nature of each of Merger Sub and the Acquired Corporation; all
property, real, personal and mixed, and all accounts payable arising in the
ordinary course of business and accrued expenses due on whatever account, and
all debts, liabilities and duties due to the Acquired Corporation shall be taken
and deemed to be transferred to and vested in the Surviving Corporation without
further act or deed; and the Surviving Corporation shall be responsible and
liable for all liabilities and obligations of the Acquired Corporation, in each
case in accordance with Delaware Corporate Law and the NY BCL.

     1.3 Consummation of the Merger. The Merger shall be effective at such time

and, collectively with the Delaware Certificate of Merger, the "CERTIFICATES OF
MERGER") is duly filed with the Secretary of State of the State of New York, as
contemplated by Section 1.10 hereof. The date and time when the Merger shall
become effective is referred to herein as the "EFFECTIVE TIME" (provided,
however, that, if the Certificates of Merger, as so filed, provide that the
Merger shall take effect, or be effective, at another time, then "EFFECTIVE
TIME," as used herein, means the time so stated in the Certificates of Merger).

     1.4 Certificate of Incorporation and Bylaws; and Directors and Officers.
The Certificate of Incorporation and Bylaws of Merger Sub, as in effect
immediately prior to the Effective Time, shall be the Certificate of
Incorporation and Bylaws of the Surviving Corporation immediately after the
Effective Time and shall thereafter continue to be its Certificate of
Incorporation and Bylaws until amended as provided therein and under Delaware
Corporate Law. The directors of Merger Sub holding office immediately prior to
the Effective Time shall be the directors of the Surviving Corporation
immediately after the Effective Time. The officers of Merger Sub holding office
immediately prior to the Effective Time shall be the officers (holding the same

value per share, of NAC (hereinafter, the common stock of NAC shall be referred
to as "NAC COMMON STOCK"), which shall be issued as provided below and shall be

                                       2

Price shall be paid by the issuance to the Stockholder of the NAC Merger SHARES.

     1.6 Conversion of Securities. At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, the Acquired
Corporation or any holder of the securities of the Acquired Corporation, each
share of the Class A common stock, par value $.001 per share, of the Acquired
Corporation (the "ORA COMMON STOCK") issued and outstanding immediately prior to
the Effective Time shall automatically be canceled and extinguished and
converted into and become the right of the holder of such share of ORA Common
Stock to receive twenty (20) shares of NAC Common Stock.

date and/or at such other time as the Parties may mutually agree upon in
writing. Simultaneously with the consummations of the Closing, the Parties shall
file, or cause to be filed, with the Secretary of State of the State of Delaware
and the Secretary of State of the State of New York, the Certificates of Merger.

     1.9 Taking of Necessary Actions; Further Actions. NAC and Merger Sub, on
the one hand, and the Acquired Corporation and the Stockholder, on the other
hand, shall use all reasonable efforts to take all such actions (including,
without limitation, actions to cause the satisfaction of the conditions of the
other to effect the Merger) as may be necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
possession of all the rights, privileges, immunities and franchises of the
Acquired Corporation, and to subject fully the Surviving Corporation to all
debts and obligations of the Acquired Corporation. The officers and directors of
the Surviving Corporation are fully authorized and directed in the name of the
Acquired Corporation and the Surviving Corporation to take, and shall take, all
such actions. Without limiting the scope or generality of the foregoing, the
Acquired Corporation and the Stockholder shall take all reasonable, commercial
efforts to obtain all Required Waivers, Required Consents and Required Approvals
(as those terms are hereinafter defined)

     1.10 Bonus Purchase Price. If the sum of (A) the Adjusted EBITDA (as
defined below) of the Acquired Corporation for the period from February 1, 2003
through the Effective Time and (B) the Adjusted EBITDA of the Surviving
Corporation for the period from the Effective Time through January 31, 2006 is
equal to or greater than Nine Hundred Thousand Dollars ($900,000), then the
Stockholder shall be entitled to receive, in addition to the Base Purchase
Price, an additional One Hundred and Fifty Thousand Dollars ($150,000) (the
"BONUS PURCHASE PRICE"). The Bonus Purchase Price shall be paid by the Surviving
Corporation, together with interest thereon at five percent (5%) per annum, in
twenty-four (24) equal quarterly installments of principal and interest
commencing with the fiscal quarter of the Surviving Corporation next following
the fiscal quarter during which the Adjusted EBITDA of the Surviving Corporation
referred to in clause (B) above has been determined. As used herein, "ADJUSTED
EBITDA" for any entity for any period means the earnings of such entity for such
period, before any deduction for interest, taxes, depreciation and amortization,
and before deducting corporate overhead or other expenses allocated to such
entity by NAC but after deducting (A) the aggregate amount of all capital
expenditures (including, without limitation, pursuant to any capital or
capitalized lease) made or required to be made by such entity (or any of its
subsidiaries) during such period and (B) any debt service paid or required to be
paid during such period by such entity (or any of its subsidiaries), including,
without limitation, any debt

                                       3

service paid or required to be paid with respect to the SBA Loan (as hereinafter
defined), the Citibank Loan (as hereinafter defined) and the Stockholder's Note

              REPRESENTATIONS AND WARRANTIES OF NAC AND MERGER SUB

     NAC and Merger Sub (collectively, the "NAC PARTIES" and each an "NAC

organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite corporate power and authority to own and operate

Incorporation and Bylaws of Merger Sub previously furnished to the Stockholder
reflect all amendments thereto and are correct and complete. As used herein,

(as currently conducted and as proposed to be conducted), business condition or
prospects or financing arrangements of such Person, "MATERIALLY ADVERSE CHANGE"
with respect to any Person means any materially adverse change in the assets,
liabilities, financial condition, operating results, customer, employee,
supplier or franchise relations, business (as currently conducted and as
proposed to be conducted), business condition or prospects or financing
arrangements of such Person, and "PERSON" means any individual, corporation,
partnership, limited liability company, joint venture, business trust,
association or other business entity of any type or nature.

     2.2 Authority Relative to This Agreement. Each NAC Party has the requisite
corporate power and authority to enter into this Agreement and each of the
Collateral Documents (as hereinafter defined) to which it is contemplated
hereunder to become a party and to carry out its obligations hereunder and
thereunder. The execution and delivery of this Agreement by each NAC Party and
the consummation by each NAC Party of the transactions contemplated hereby to be
performed by it have been duly authorized by the Board of Directors such NAC
Party, and no other corporate proceedings on the part of either NAC Party are
necessary to authorize this Agreement and such transactions. The execution and
delivery of each Collateral Document to which either NAC Party is contemplated
hereunder to become a party and the consummation by such NAC Party of the
transactions contemplated thereby to be performed by it have been duly
authorized by the Board of Directors of such NAC Party, and no other corporate
proceedings on the part of such NAC Party are necessary to authorize such
Collateral Document and such transactions. This Agreement has been duly executed
and delivered by each NAC Party and constitutes a valid and binding obligation

insolvency, reorganization or other similar laws relating to the enforcement of
creditors' rights generally and by general principles of equity. The execution,
delivery and performance of this Agreement by either NAC Party is not, and will
not be, in breach or violation of, or be in conflict with or constitute, with or

or understanding to which such NAC Party is a party or by which it is otherwise

constitute grounds for, the termination, suspension, revocation, forfeiture,
lapse, impairment or non-renewal of any Permit the absence or

                                       4

loss of which would have or could be reasonably anticipated to have a Materially
Adverse Effect on NAC. The execution, delivery and performance of any Collateral
Document by either NAC Party that is contemplated hereunder to become a party
thereto will not be in breach or violation of, or be in conflict with or
constitute, with or without the passage of time or the giving of notice (or
both), a default under, (a) the Certificate of Incorporation or Bylaws of such
NAC Party, (b) any agreement, arrangement or understanding to which such NAC
Party is a party or by which such NAC Party is otherwise bound, (c) any Permit
applicable to such NAC Party or (d) any law, regulation, order, judgment or
decree applicable to such NAC Party and will not result in the creation of any
Lien on any assets of such NAC Party or of any of its current subsidiaries or

Adverse Effect on NAC. Except for such filings to be made pursuant to Delaware
Corporate Law in order to effect the Merger (which NAC agrees to make) or
pursuant to federal or state securities laws, no authorization, consent or
approval of, or filing with, any public body, court or authority is (a)

herein, "COLLATERAL DOCUMENTS" mean, collectively, the Employment Agreement, the
Non-Competition Agreement (as hereinafter defined), the Stockholder's Note and
the Registration Rights Agreement (as hereinafter defined).

     2.3 No Materially Adverse Changes. Except as set forth in Section 2.3 of
the letter, dated as of the date hereof, furnished by NAC to the Stockholder
(the "NAC DISCLOSURE LETTER"), a copy of which letter is attached hereto as
Exhibit D, or in the NAC Business Reports (as defined in Section 2.6 below),
there has not been any Materially Adverse Change with respect to NAC since
January 1, 2002.

     2.4 Validity of Stock. The NAC Merger Shares shall, when issued: (i) be
duly authorized, validly issued, fully paid and non-assessable and free of liens
and encumbrances created by any person other than the Stockholder, and (ii) be
free and clear of any transfer restrictions, liens and encumbrances except for
restrictions on transfer under applicable federal and state securities laws,
including Rule 144 promulgated under the Securities Act of 1933, as amended,
(the "SECURITIES ACT") and except as provided for in this Agreement.

     2.5 Capitalization. The authorized equity capitalization of NAC consists of
40,000,000 shares of NAC Common Stock and 2,000,000 shares of Preferred Stock.
As of the date hereof, 7,830,614 shares of NAC Common Stock are issued and
outstanding, and except as set forth in Section 2.5 of the NAC Disclosure
Letter, as of the Closing there will be 7,830,614 shares of NAC Common Stock
issued and outstanding (exclusive of any shares of NAC Common Stock contemplated
to be issued to the Stockholder pursuant to this Agreement), all of which shares
are validly issued, fully paid and non-assessable, and no shares of Preferred
Stock are outstanding. Except as disclosed in Section 2.5 of the NAC Disclosure
Letter or in the NAC Business Reports or provided for herein or any of the
Post-Merger Agreements (as hereinafter defined), there are no options, warrants,
conversion privileges or other rights, agreements, arrangements or commitments
obligating NAC to issue or sell any shares of capital stock of NAC or securities
or obligations of any kind convertible into or exchangeable for any shares of
capital stock of NAC or of any other corporation, nor are there any stock
appreciation, phantom stock or similar rights outstanding based upon the book
value or any other attribute of NAC. Except as disclosed in the NAC Business
Reports, no holders of outstanding shares of NAC Common Stock are entitled to
any preemptive or other similar rights.

     2.6 Financial Statements and SEC Filings. NAC has made available to the
Stockholder and correct copies of each report, registration statement (on a form
other than Form S-8) and definitive proxy statement (collectively, the
"REPORTS") filed by NAC with the U.S. Securities and Exchange Commission (the
"SEC")

<PAGE>

between January 31, 2002 and the date of this Agreement. NAC will also deliver
to the Stockholder on or before the Closing, any other reports that are filed
with the SEC after the date hereof and prior to the Closing, and any other
reports or other information sent generally to NAC's stockholders after the date
hereof, but not required to be filed with the SEC. (The Reports and all other
reports and information referred to in the immediately preceding sentence,
whether or not filed with the SEC, are herein collectively referred to as the
"NAC BUSINESS REPORTS," and the financial statements, including the notes
thereto, contained in the NAC Business Reports are hereinafter collectively
referred to as the "NAC FINANCIAL STATEMENTS"). NAC has duly filed all the
Reports required to be filed by it with the SEC under the Securities Act and the
Securities Exchange Act of 1934, as amended, and no such Report, nor any Report
sent to NAC's stockholders generally, contains any untrue statement of material
fact or omits to state any material fact required to be stated therein or
necessary to make the statements in such Report, in light of the circumstances
under which they were made, not misleading. The NAC Financial Statements were
prepared in accordance with generally accepted accounting principles ("GAAP")
applied on a consistent basis throughout the periods involved and present fairly
the consolidated financial condition, results of operations and cash flows of
NAC and its consolidated subsidiaries as of the dates and for the periods
indicated therein, subject, in the case of unaudited interim statements, to
normal year-end accounting adjustments and the absence of complete footnote
disclosure.

     2.7 Absence of Undisclosed Liabilities. Except as and to the extent stated
in Section 2.7 of the NAC Disclosure Letter or in the NAC Financial Statements
or otherwise in the NAC Business Reports, NAC does not have any material
liabilities or obligations (whether accrued, absolute, contingent, unliquidated,
known, unknown or otherwise), other than (i) liabilities incurred in the
ordinary course of business and (ii) obligations under contracts and commitments
incurred in the ordinary course of business, which, in both subsections (i) and
(ii), individually or in the aggregate, are not material to the financial
condition or operating results of NAC (determined on a consolidated basis).

     2.8 Litigation. Except as set forth in Section 2.8 of the NAC Disclosure
Letter or in the NAC Business Reports, there are (a) no actions, suits,
proceedings or orders, at law or in equity, pending or threatened against NAC,
(b) to the best information and belief of NAC, no investigations pending or
threatened against NAC before or by any federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, and (c) no bases known to NAC for any of the foregoing.

     2.9 No Commissions. NAC has not incurred any obligation for any finder's or
broker's or agent's fees or commissions or similar compensation in connection
with the transactions contemplated hereby.

     2.10 No Liabilities of Merger Sub. Except for its obligations under this
Agreement or any Collateral Document, Merger Sub is not subject to any
liabilities, obligations or claims, whether absolute or contingent, liquidated
or unliquidated, known or unknown. Merger Sub was formed solely for the purpose
of consummating the transactions contemplated by this Agreement and, except as
provided for herein or contemplated hereby, has not engaged in any business or
other activities for any other purpose.

     2.11 Governmental Consents. No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of NAC or Merger Sub
is required in connection with the consummation of the transactions contemplated
by this Agreement or any of the Collateral Documents, except (a) the filing of
the Delaware Certificate of Merger with the Secretary of State of Delaware and
filing of the NY Certificate of Merger with the Secretary of State of New York
and (b) such filings as may be required under federal and/or state securities
laws, which filings NAC agrees to make to the extent (but only to the extent)
expressly provided for in the Registration

                                       6
<PAGE>

Rights Agreement. The foregoing representation and warranty set forth in this
Section 2.11 are subject to and conditioned upon the truth and accuracy of the
representations of the Stockholder as set forth in Article 4 below.

     2.12 Disclosure. Neither this Article 2 nor the NAC Disclosure Letter
contains any untrue statement of a material fact or omits a material fact
necessary to make the statements contained herein or therein, in light of the
circumstances under which they were made, not misleading, and there is no fact
known to NAC that has not been disclosed to the Stockholder that materially and
adversely affects, or could reasonably be anticipated to materially and
adversely affect, the business, including the operating results, assets,
customer, supplier or employee relations and business prospects, of NAC
(determined on a consolidated basis); provided, however, that the foregoing
shall not be deemed to extend or apply to any fact or circumstance that relates
to the Acquired Corporation (including, without limitation, the operating
results, assets, customer, supplier or employee relations or business prospects
of the Acquired Corporation).

     2.13 Reorganization Matters.

     (a)  NAC has, and at the Effective Time will have, no plan or intention to:

          (iii)     Sell or otherwise dispose of the stock of Merger Sub except

                    in the ordinary course of business (including, without
                    limitation, dispositions of obsolete or damaged property),
                    (ii) transfers described in Section 368(a)(2)(C) of the
                    Code; (iii) transfers to members of the "qualified group"

                    1.368-1(d)(4)(ii)) encompassing NAC (the "NAC GROUP")
                    following the Effective Time, or (iv) transfers to a
                    partnership if either (x) members of the NAC Group, in the
                    aggregate, own a significant interest in that partnership
                    business or (y) one or more members of the NAC Group have
                    active and substantial management functions as a partner
                    with respect to that partnership business;

          (v)       Cause Merger Sub to issue additional shares of stock that
                    would result in NAC losing "control" (within the meaning of
                    Section 368(c) of the Code) of Merger Sub following the
                    Effective Time;

          (vi)      Cause Merger Sub or the NAC Group following the Effective
                    Time to discontinue the historic business conducted by
                    Merger Sub preceding the Effective Time or fail to use in a
                    business a significant portion of the assets held by Merger
                    Sub immediately preceding the Effective Time;

          (vii)     Acquire or cause any person "related" (within the meaning of
                    Treasury Regulations Section 1.368-1(e)(3)) to NAC to
                    acquire any of the NAC Common Stock issued in the Merger; or

          (viii)    Take any action that might otherwise cause the Merger not to
                    be treated as a "reorganization" within the meaning of
                    Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code.

                                       7

     (b)  Prior to the Effective Time, neither NAC nor any person "related" to
          NAC will, "in connection with" the Merger, acquire, directly or
          indirectly, any shares of capital stock of the Acquired Corporation.
          For purposes hereof, the term "related" has the meaning in Treasury
          Regulations Section 1.368-1(e)(3), and the term "in connection with"
          has the meaning in Treasury Regulations Section 1.368-1(e)(2).

respect under any of such Permit. The consummation of the Merger and the other
transactions contemplated hereby and by the Collateral Documents will not result

any waiver of any statute of limitations on the assessment or collection of any

Acquired Corporation pending, or to the best information and belief the
Stockholder Parties, threatened, that would have, or could reasonably be
anticipated to have, a Materially Adverse Effect on the Acquired Corporation,

          ADDITIONAL REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER

     The Stockholder represents and warrants to NAC and Merger Sub as follows:

     4.1 Authority. The Stockholder has the power and authority to enter into
this Agreement and each of the Collateral Documents to which he or it is
contemplated hereunder to become a party and to carry out his obligations
hereunder and thereunder. This Agreement has been duly executed by the
Stockholder and constitutes a valid and binding obligation of the Stockholder,
enforceable against him in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization
or other similar laws relating to the enforcement of creditors' rights generally
and by general principles of equity. Each Collateral Document to which the
Stockholder is contemplated hereunder to become a party will, when executed and
delivered by the Stockholder, constitute a valid and binding obligation of the
Stockholder, enforceable against him in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization
or other similar laws relating to the enforcement of creditors' rights


                                       16
<PAGE>

generally and by general principles of equity. The execution, delivery
and performance of this Agreement by the Stockholder is not, and will not be, in
breach or violation of (a) any agreement, arrangement or understanding to which
the Stockholder is a party or by which he is otherwise bound, (b) any license,
franchise or permit applicable to the Stockholder or (c) any law, regulation,
order, judgment or decree applicable to the Stockholder. The execution, delivery
and performance of any Collateral Document by the Stockholder contemplated
hereunder to become a party thereto will not be in breach or violation of (a)
any agreement, arrangement or understanding to which the Stockholder is a party
or by which he is otherwise bound, (b) any license, franchise or permit
applicable to the Stockholder or (c) any law, regulation, order, judgment or
decree applicable to the Stockholder. No authorization, consent or approval of,
or filing with, any public body, court or authority is necessary on the part of
the Stockholder for the consummation by him of the transactions contemplated by
this Agreement to be performed by him.

     4.2 Stock Ownership. The Stockholder is the legal and beneficial owner of
all of the issued and outstanding shares of the capital stock of the Acquired
Corporation, free and clear of all Liens, other than restrictions under federal
and state securities laws. Any and all proxies and similar rights that may have
been given by the Stockholder prior to this Agreement regarding any shares of
capital stock of the Acquired Corporation have been revoked and are not longer
outstanding or of any force or effect

     4.3 Purchase Entirely for Own Account. The NAC Merger Shares to be received
by the Stockholder will be acquired for investment only and for the
Stockholder's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and the Stockholder has no present
intention of selling, granting any participation in or otherwise distributing or
disposing of the same. By executing this Agreement, the Stockholder further
represents that he does not have any contract, undertaking, agreement or
arrangement with any Person to sell, transfer or grant participations to such
Person or to any other Person, with respect to any of the NAC Merger Shares.

     4.4 Disclosure of Information. The Stockholder believes that he has
received all the information he or it considers necessary or appropriate for
deciding whether to receive the NAC Merger Shares contemplated hereunder to be
issued to him. The Stockholder has had an opportunity to ask questions and
receive answers from NAC and its management regarding the business, properties,
prospects and financial condition of NAC.

     4.5 Investment Experience. The Stockholder acknowledges that he is able to
fend for himself, can bear the economic risk of his investment and has such
knowledge and experience in financial or business matters that he is capable of
evaluating the merits and risks of the investment of owning the NAC Merger
Shares contemplated hereunder to be issued to him. The Stockholder is an
accredited investor, as that term is defined in Rule 501 promulgated under the
Securities Act.

     4.6 Restricted Securities. The Stockholder understands that the NAC Merger
Shares he is acquiring are characterized as "restricted securities" under the
federal securities laws inasmuch as they are being acquired from NAC in a
transaction not involving a public offering and that, under such laws and
applicable regulations, such securities may be resold without registration under
the Securities Act only in certain limited circumstances. In this connection,
the Stockholder represents that he is familiar with SEC Rule 144, as presently
in effect, and understands the resale limitations imposed thereby and by the
Securities Act.

     4.7 Holding Period. The Stockholder agrees that, for a period of one year
from the Effective Time, he will not transfer or otherwise dispose of the NAC
Merger Shares (or any of them) being issued to him pursuant to the terms of this
Agreement.

                                       17
<PAGE>

     4.8 Ownership of Shares. There are no obligations of the Stockholder to
sell or to acquire any of the shares of capital stock of the Acquired
Corporation except pursuant to this Agreement. With respect to all of the
Stockholder's shares of capital stock of the Acquired Corporation, the
Stockholder has sole voting power and sole power to issue instructions with
respect to the matters herein, sole power of disposition, sole power of
conversion, sole power to demand appraisal rights and sole power to agree to all
of the matters set forth in this Agreement, in each case with no limitations,
qualifications or restrictions on such rights, subject, however, to applicable
securities laws and the terms of this Agreement.

     4.9 Guaranteed Obligations. Except as expressly set forth in reasonable
detail in Part A of Section 4.9 of the ORA Disclosure Letter, the Stockholder
has not agreed to act as a guarantor or surety with respect to any obligation or
liability of the Acquired Corporation (all such obligations and liabilities, as
so expressly set forth in reasonable detail in Part A of Section 4.9 of the ORA
Disclosure Letter, are hereinafter referred to collectively as the "GUARANTEED
OBLIGATIONS"). The Stockholder has provided NAC with true, complete and accurate
copies of each (a) guaranty and surety agreement or other document (including
all amendments, supplements and other modifications thereof or thereto) pursuant
to which Stockholder has agreed to act as a guarantor or surety with respect to
any obligation or liability of the Acquired Corporation (each such guaranty and
surety agreement or other document that is listed in Part B of Section 4.9 of
the ORA Disclosure Letter, a "STOCKHOLDER GUARANTY") and (b) loan agreement,
lease or other document (including all amendments, supplements and other
modifications thereof or thereto) that set forth any obligation or liability
with respect to which the Stockholder has agreed to act as a guarantor or surety
(each such loan agreement, lease or other document that is listed in Part C of
Section 4.9 of the ORA Disclosure Letter, a "GUARANTEED CONTRACT").

     4.10 Legends. It is understood that the Securities Act restricts the
transferability of securities, such as the NAC Merger Shares, issued in reliance
upon the exemption from the registration requirements of the Securities Act
provided by Section 4(2) thereunder, and that the certificates evidencing any of
the NAC Merger Shares will bear the following legend (in addition to such other
legends as may be required by law or contract):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY
     OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH
     SECURITIES LAWS. THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
     SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
     OTHER THAN PURSUANT TO THE PROVISIONS OF THE SECURITIES ACT OR AN EXEMPTION
     FROM REGISTRATION THEREUNDER. THE HOLDER OF THIS CERTIFICATE AGREES THAT
     IT/HE/SHE WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED
     (UNLESS SUCH SECURITY IS TRANSFERRED PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE SECURITIES ACT) A NOTICE SUBSTANTIALLY TO THE EFFECT OF
     THIS LEGEND.

Corporation shall bear the expenses for the audit of the Acquired Corporation,

reimburse the Surviving Corporation for) any and all taxes that may become due
and payable by the Acquired Corporation (or the Surviving Corporation as the
successor to the Acquired Corporations) as a consequence of the consummation of

obligate the Stockholder to bear (or to reimburse the Surviving Corporation for)
any income or other taxes of the Surviving Corporation that accrue and become
payable following consummation of the Merger.

     5.5 Notification of Certain Matters. Each Party shall give prompt notice to
the others of (a) the occurrence or failure to occur of any event, which

     (b) To facilitate the due diligence review, (i) NAC shall provide to the
     Stockholder and his agents complete access to all of its records and
     documents, shall provide the Stockholder with bank and professional
     references and shall use reasonable efforts to make available for
     consultation its customers and suppliers and (ii) the Stockholder shall

     Party will be treated as confidential, and if this Agreement is terminated,
     will return to the Party providing same all confidential documents (and all
     copies thereof) in its or his possession, or will certify to such Party
     that all such documents not returned have been destroyed; provided however,
     that, in the event the Merger is consummated, this provision shall not

                            POST CLOSING OBLIGATIONS

     7.1 Adjustments to Payment of Purchase Price. The determination of the Base
Purchase Price as set forth above was based upon the premise and assumption that
the Net Indebtedness Position (as hereinafter defined) of the Acquired
Corporation at the time of the Closing would be at least thirty-two thousand
dollars ($32,000) (the "BASE AMOUNT"). In the event the Net Indebtedness
Position of the Acquired Corporation at the time of the Closing is not equal to
at least the Base Amount, then the Base Purchase Price shall be adjusted, at the
election of NAC, by either (i) reducing of the outstanding principal amount of
the Stockholder's Note by the amount of the Shortfall (as hereinafter defined)
or (ii) multiplying the 200,000 shares of NAC Common Stock presumed to be the
correct amount of the Base Purchase Price by a fraction, the numerator of which
is the amount of the Shortfall and the denominator of which is the Base Amount,
with the number of shares of NAC Common Stock resulting from such calculation to
be returned to NAC as provided below. As used herein, the "NET INDEBTEDNESS
POSITION" of the Acquired Corporation at any time means the amount, if any, by
which the amount of nine hundred and fifty thousand dollars ($950,000.00)
exceeds the aggregate Outstanding Indebtedness (as hereinafter defined) of the
Acquired Corporation as of such time, "SHORTFALL" means the amount, if any, by
which the Base Amount exceeds the actual Net Indebtedness Position of the
Acquired Corporation at the time of the Closing, and the "OUTSTANDING
INDEBTEDNESS" of the Acquired Corporation as of any time means, as of such time,
(I) the aggregate outstanding amount (inclusive of principal, accrued but unpaid
interest and all fees and charges then due) owed by the Acquired Corporation for
borrowed money, which shall include, without limitation, (A) all amounts owed by
the Acquired Corporation to SBA Bank pursuant to or as contemplated by that
certain Loan Agreement, dated as of April 25, 2002, by and between the Acquired
Corporation and SBA Bank (such Loan Agreement, collectively with all related
loan documentation, including any surety, guaranty, security agreement, pledge
agreement or other agreement related thereto, the "SBA LOAN DOCUMENTS" and the
loan covered thereby, the "SBA LOAN"), (B) all amounts owed by the

                                       22
<PAGE>

Acquired Corporation to Citibank NA pursuant to or as contemplated by that
certain Loan Agreement and Line of Credit Agreement, dated as of July 1, 2001,
by and between the Acquired Corporation and Citibank NA (such Loan Agreement and
Line of Credit Agreement, collectively with all related loan documentation,
including any surety, guaranty, security agreement, pledge agreement or other
agreement related thereto, the "CITIBANK LOAN DOCUMENTS" and the loan covered
thereby, the "CITIBANK LOAN"), (C) all amounts owed by the Acquired Corporation
under or pursuant to any capital or capitalized lease (including, without
limitation, those leases listed in Part B of Section 3.4(a) of the ORA
Disclosure Letter (any such capital or capitalized lease, collectively with all
related lease documentation, a "CAPITAL LEASE") and (D) all repayment
obligations, exclusive of $115,000 of accrued compensation due to the
Stockholder, owed by the Acquired Corporation to the Stockholder, which
obligations shall be evidenced by a certain promissory note (the "STOCKHOLDER'S
NOTE"), dated the date of the Closing and issued by the Acquired Corporation to
the order of the Stockholder in the stated principal amount of one hundred and
fifty-three thousand dollars ($153,000) and otherwise in the form and substance
of Exhibit C attached hereto, plus (II) the aggregate amount at such time or
thereafter payable by the Acquired Corporation pursuant to any Capital Lease. If
the foregoing results in an adjustment in the number of shares of NAC Common
Stock that should have been issued to the Stockholder for the Base Purchase
Price, then such adjustment shall be made by the Stockholder, as promptly as
practical following NAC's request therefor, returning to NAC for cancellation an
appropriate number of the shares of NAC Common Stock it received at the Closing
in payment of the Base Purchase Price.

     7.2 Recharacterization of NAC Merger Shares. In the event the Stockholder
is required, as contemplated by Section 7.1 above, to return any of the shares
of NAC Common Stock initially issued to him at the Closing as contemplated under

     7.2 Timing of Adjustments. Any adjustments required by this Article 7 shall
be made within four (4) calendar months following the Effective Time or, if the
amount of the Outstanding Indebtedness is determined by arbitration as
contemplated by Section 10.12 below, within thirty (30) days after the amount of
the Outstanding Indebtedness has been so determined.

     7.3 Delivery of Audited Financial. The Stockholder shall deliver, or cause
to be delivered to NAC, within thirty-five (35) days following the Closing,
audited balance sheets (as of the date of the Closing and as of the end of each

thereunder, NAC shall promptly (and, in any event, within thirty (30) days
following payment by the Stockholder and receipt of demand therefor from
Stockholder, which demand is accompanied with appropriate proof of payment by
Stockholder) reimburse the Stockholder for such payment; provided, however,
that, if any claim shall be made against the Stockholder under or with respect
to any Stockholder Guaranty, the Stockholder shall give prompt written notice
thereof to NAC and NAC shall be entitled, with counsel selected by it, to defend
against and settle such claim in the name of and on behalf of the Stockholder.

     8.2 Acquired Corporations and Stockholder to Indemnify.

     (a) General. Subject to the limitations in this Article 8, the Stockholder
     and (subject to Section 8.8 below) the Acquired Corporation, jointly and
     severally, agree to indemnify and hold harmless NAC and Merger Sub and
     their respective directors, officers, employees and agents from and against
     all proceedings, judgments, decrees, demands, claims, actions, losses,
     damages, liabilities, costs and expenses, including, without limitation,
     reasonable attorneys' fees and costs, (collectively referred to as
     "LOSSES") asserted against or incurred by NAC, Merger Sub or their
     respective directors, officers, employees or agents resulting from (i) a
     breach of any covenant, agreement, representation or warranty of the
     Acquired Corporation or the Stockholder contained in this Agreement, the
     exhibits hereto (exclusive of the Collateral Documents) or any certificate,
     document or instrument (other than the Collateral Documents, but including
     the ORA Disclosure Letter) delivered by or on behalf of the Acquired
     Corporation or the Stockholder pursuant hereto or as contemplated hereby or
     (ii) the assertion by any third party of a claim (a "THIRD PARTY CLAIM")
     that, if true, would constitute such a breach.

     (b) Tax Matters. The Acquired Corporation and the Stockholder, jointly and
     severally, also agree to indemnify, hold harmless and defend NAC and Merger
     Sub from and against any and all assessments, claims and liability
     (including, without limitation, any interest or other penalty) relating to
     (i) any failure to file federal, state or local tax returns or amended
     returns for the Acquired Corporation for any period, including short
     periods, for which a return was due, including any extensions, prior to or
     ending on the Effective Time; (ii) for any non-payment by the Acquired
     Corporation of federal, state or local taxes due for any period, including
     short periods, for which a return was due prior to or ending on the
     Effective Time; (iii) for any errors or omissions related to any federal,
     state or local tax returns, and the elections thereunder, filed by the
     Acquired Corporation for any period, including short periods, for which a
     return was due prior to or ending on the Effective Time; or (iv) any taxes
     that may become due as a result of any breach of any representation or
     warranty of the Acquired Corporation and/or the Stockholder set forth in
     this Agreement.

     8.3 NAC and Merger Sub to Indemnify. Subject to the limitations in this
Article 8, NAC and Merger Sub, jointly and severally, hereby agree to indemnify
and hold harmless the Stockholder and his agents from and against all Losses
asserted against or incurred by the Stockholder and his agents resulting from
(i) a breach of any covenant, agreement, representation or warranty of NAC or
Merger Sub contained in this Agreement, the exhibits hereto (exclusive of the
Collateral Documents, but including the NAC Disclosure Letter) or any
certificate, document or instrument (other than the Collateral Documents)
delivered by or on behalf of NAC or Merger Sub pursuant hereto or as
contemplated hereby or (ii) the assertion of any Third Party Claim that, if
true, would constitute such a breach.

     8.4 Notice of Claim. Any Party that or who has a claim that would give rise
to liability pursuant to this Article 8 shall give prompt notice to all other
Parties of such claim, together with a reasonable description thereof. With
respect to any Third Party Claim that is covered by the indemnifications
contained hereunder, the Party obligated to indemnify shall be afforded the
opportunity, at its expense, to defend or settle such Claim if, within ten (10)
business days of notice thereof, it acknowledges in writing its or his
indemnification obligation

                                       24
<PAGE>

     hereunder, utilizes counsel reasonably satisfactory to the indemnified
     party, commences such defense promptly and pursues such defense with
     diligence; provided, however, that such indemnifying party shall secure the
     consent of the indemnified party to any settlement, which consent shall not
     be unreasonably withheld or delayed. If any indemnified party defends
     against any Third Party Claim hereunder, such party shall use reasonable
     efforts in such defense and to mitigate Losses arising thereunder. In the
     event any indemnified party is indemnified hereunder with respect to any
     Third Party Claim the defense of which has been undertaken by a Party that
     is obligated hereunder to indemnify such indemnified party with respect to
     such Claim, such indemnified party shall promptly and fully cooperate with
     the indemnifying party in such defense.

     8.5 Certain Limitations.

     (a) Cap. The limit on the indemnification liability of the Stockholder and
     the Acquired Corporation under Section 8.2(a) and the limit on the
     indemnification liability of NAC and Merger Sub under Section 8.3 (each of
     such limits shall be referred to as a "CAP") shall be an amount equal to
     the Purchase Price plus (with respect to the indemnification liability of
     the Stockholder) the amount of the Stockholder Note, the amount of any
     payments paid or payable to the Stockholder pursuant to the Employment
     Agreement and the amount paid by NAC pursuant to Section 7.4 above.

     (b) Basket. Neither the Stockholder, considered as a party on one hand, nor
     NAC and Merger Sub, considered as a party on the other hand, shall be
     required to indemnify the other such party for any Losses relating to any
     matter subject to indemnification under this Article 8 unless and until
     such Losses exceed fifty thousand dollars ($50,000) (the "BASKET AMOUNT"),
     but in the event the Losses exceed the Basket Amount, the Party responsible
     therefor shall be liable and responsible for the full amount of such Losses
     without reduction for the Basket Amount.

     (c) Inapplicability of Cap and Basket. The Basket and Cap shall not apply
     to any breach of this Agreement constituting fraud or any intentional
     misstatement, any liability under or with respect to Section 8.2(b) above
     or any liability under or with respect to any breach of any of the
     Collateral Documents.

     8.6 Satisfaction of Obligations. If any indemnifying party becomes
obligated to indemnify another party with respect to any claim for
indemnification hereunder and the amount of liability with respect thereto shall
have been finally determined, subject to the limitations set forth in Section
8.5 above, the indemnifying party shall pay such amount to the indemnified
party.

     8.7 Exclusive Remedy at Law. This Article 8 provides the sole and exclusive
remedy at law of each of the Parties in any cause of action based thereon
(subject to the exception in Section 8.5(c) hereof) against the Parties for any
inaccuracy, misrepresentation or default in, or breach of, any of the
representations, warranties or covenants given or made by the Parties in this
Agreement, any exhibit hereto (excluding, however, the Collateral Documents, but
including the NAC Disclosure Letter and ORA Disclosure Letter, as applicable) or
in any certificate, document or instrument (other than the Collateral Documents)
delivered by or on behalf of any Party pursuant hereto. Nothing contained
herein, however, shall be construed as limiting any rights or remedies in
equity, including without limitation, the right of specific performance.

     8.8 Right to Proceed Against the Stockholder. In the event the Merger is
consummated, NAC and Merger Sub shall be permitted, and authorized, to proceed
(at their option) only against the Stockholder with respect to the
indemnification set forth above in this Article 8, and in the event of any
recovery from the Stockholder on account of or with respect to such indemnity,
the Stockholder shall not be entitled to seek or obtain from the Acquired
Corporation (or the Surviving Corporation as the successor to the Acquired

                                       25
<PAGE>

Corporations) any payment or contribution with respect to such recovery. THE
STOCKHOLDER hereby expressly waives the right to seek or obtain from THE
Acquired Corporation (or the Surviving Corporation as the successor to the
Acquired Corporations) any payment or contribution with respect to any such
recovery.

                                    ARTICLE 9

                        TERMINATION, AMENDMENT AND WAIVER

Effective Time:

     (a) by mutual consent of the Stockholder and a duly authorized officer of
     NAC;

     (b) by NAC or Merger Sub if the Acquired Corporation or the Stockholder
     breaches any of its or his material representations, warranties or
     covenants contained herein and such breach is not curable or, if is
     curable, is not cured within fifteen (15) business days after receipt of
     written notice thereof, or by the Acquired Corporation or the Stockholder
     if NAC or Merger Sub breaches any of its material representations,
     warranties or covenants contained herein and such breach is not curable or,
     if curable, is not cured within fifteen (15) business days after receipt of
     written notice thereof;

     (c) by either NAC Party if the conditions to close the transactions
     contemplated by this Agreement shall become incapable of satisfaction other
     than on account of any action or inaction by either NAC Party, or by either
     Stockholder Party if the conditions to close the transactions contemplated
     by this Agreement shall become incapable of satisfaction other than on
     account of any action or inaction by either Stockholder Party; or

     (d) by any of NAC, Merger Sub, the Acquired Corporations and the
     Stockholder if all of the conditions to consummation of the Merger shall
     not have occurred, or been satisfied or waived, by April 30, 2003;
     provided, however, that neither NAC Party shall have the right to terminate
     this Agreement unilaterally if the event giving rise to such right shall be
     primarily attributable to either NAC Party or to any Person affiliated with
     either NAC Party and neither Stockholder Party shall have the right to
     terminate this Agreement unilaterally if the event giving rise to such
     right shall be primarily attributable to either Stockholder Party or to any
     Person affiliated with either Stockholder Party.

     9.2 Effect of Termination. In the event of termination of this Agreement as
provided in Section 9.1 hereof, this Agreement shall become void, and there
shall be no liability or further obligation hereunder on the part of any Party
or its respective stockholders (including the Stockholder), officers or
directors, except as set forth in Article 8 hereof, except for liability arising
from a willful breach of this Agreement and except for liability with respect to
any provision hereof that by its terms expressly survives the termination of
this Agreement.

     10.13 Waiver of Jury Trial; Consent to Jurisdiction. EACH OF THE PARTIES
EXPRESSLY WAIVES ITS OR HIS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY SUIT,
LITIGATION OR OTHER JUDICIAL PROCEEDING REGARDING THIS AGREEMENT OR ANY
COLLATERAL DOCUMENT OR ANY DISPUTE HEREUNDER OR THEREUNDER OR RELATING HERETO OR
THERETO. This Agreement and each of the Collateral Documents shall be governed
by, interpreted under and construed in accordance with the internal laws of the
State of New York applicable to contracts executed and to be performed wholly
within that State without giving effect to the choice or conflict of laws
principles or provisions thereof, except to the extent any provision hereof or
thereof must be governed by, interpreted under or construed in accordance with
the laws of the State of Delaware. Each of the Parties agrees that any dispute
under or with respect to this Agreement or any of the Collateral Documents shall
(subject to Section 10.14 below) be determined before the state or federal
courts situated in the City, County and State of New York, which courts shall
have exclusive jurisdiction over and with respect to any such dispute, and each
of the Parties hereby irrevocably submits to the jurisdiction of such courts.
Each Party hereby agrees not to raise any defense or objection, under the theory
of forum non conveniens or otherwise, with respect to the jurisdiction of any
such court. In addition to such other method as may available under applicable
law, each Party agrees that any summons, complaint or other papers or process in
connection with any such dispute (including any dispute contemplated by Section
10.14 below) may be served on it or him in the same manner in which a Notice may
be given to it or him pursuant to Section 10.2 above.

     10.14 Dispute Resolution and Arbitration. Subject to clause (c) below, if
any dispute arises between or among any of the Parties regarding or relating to
this Agreement or (unless otherwise expressly provided for therein) any
Collateral Document (including, without limitation, any aspect of Thompson's
obligations under the Employment Agreement), then, IN LIEU OF LITIGATION, the
Parties consent and agree to resolve such dispute through mandatory arbitration
under the Commercial Rules of the American Arbitration Association (the "AAA"),
before a single, independent arbitrator (which arbitrator shall, subject to
clause (b) below, be a retired judge of any Federal Court or a retired judge who
has served as a judge in civil proceedings in New York at the Supreme Court
level or on a more senior court in the State of New York). Any such arbitrator
shall be selected by mutual agreement of the parties to such arbitration, but in
the event such parties cannot agree upon the selection of such arbitrator, the
AAA located in New York City shall appoint such arbitrator in accordance with
the commercial arbitration rules of the AAA. Any arbitration proceeding
contemplated hereunder shall be conducted in New York City, New York. The
Parties consent to the entry of judgment upon award rendered by the arbitrator
in any court of competent jurisdiction. Without limiting the generality or scope
of the foregoing, all disputes (except as otherwise herein or in the applicable
Collateral Document expressly provided) under or with respect to this Agreement
or any Collateral Document shall be subject to arbitration as herein provided,
which disputes may include, without limitation, any claim or dispute with
respect to (i) the enforceability of this Agreement or any Collateral Document
(or any provision hereof or thereof), (ii) whether this Agreement or any
Collateral Document was induced by fraud or coercion and (iii) whether any Party
is entitled to rescission or any other remedy.

     (a) Notwithstanding the foregoing, if the dispute relates to a
     determination of the amount of the Outstanding Indebtedness hereunder or
     any other financial amount under any of the Collateral Documents, such
     dispute shall be resolved in accordance with clause (a) above but the
     single arbitrator shall be an individual with substantial experience in
     auditing public companies.

     (b) Notwithstanding the foregoing, if any suit or other judicial proceeding
     is commenced asserting a Third Party Claim against any Party and if such
     Third Party Claim would or could give rise to a claim for indemnification
     by such Party under Article 8 above, then, at the election of such Party,
     the Party obligated hereunder to indemnify with respect to such Claim may
     be joined in such suit or other judicial

                                      29
<PAGE>

     proceeding so that all matters related thereto (including the obligation,
     if any, of any Party to indemnify another Party with respect to such Claim)
     may be resolved in such suit or other legal proceeding.

     (c) Notwithstanding the foregoing, however, should adequate grounds exist
     for seeking immediate injunctive or other equitable relief hereunder or
     under any Collateral Document, any Party may seek and obtain such relief
     through a judicial proceeding or action in accordance with Section 10.13
     above, provided that, upon obtaining such relief, any further proceeding in
     such judicial proceeding or action (exclusive of any appeal) shall be
     stayed pending the resolution of the arbitration proceedings called for
     herein.

     (d) With respect to any arbitration contemplated by this Section 10.14,
     each Party shall, subject to Article 8 above, bear its or his own costs;
     however, any fees assessed by the AAA shall be allocated by the arbitrator
     in his or her sole discretion.
