     Section 3.1    Conversion of Shares of ConQuest Stock.

          (a)  Each share of ConQuest Common Stock issued and outstanding at the

Effective Time, except as otherwise provided in the last sentence of

subparagraph (c), shall, as of the Effective Time, by virtue of the Merger and

without any action on the part of the holder thereof, be converted into the

right to receive 0.9617 shares of Excalibur Common Stock, except as provided in

Section 3.1(b) below.  For the purposes of this Agreement, "ConQuest Common

Stock" shall mean ConQuest's Common Stock, without par value; and "Excalibur

Common Stock" shall mean Excalibur's Common Stock, $.01 par value per share.



          (b)  No fraction of a share of Excalibur Common Stock shall be issued.

Each holder of a certificate or certificates representing shares of ConQuest

Common Stock issued

and outstanding immediately prior to the Effective Time who would otherwise be

entitled to receive a fractional share of Excalibur Common Stock (after taking

into account all shares of ConQuest Common Stock then held by such holder) shall

receive only the whole number of shares of Excalibur Common Stock into which

such holder's ConQuest Common Stock is converted under Section 3.1(a) above.



          (c)  The Excalibur Common Stock to be received upon the conversion

ConQuest Common Stock pursuant to the Merger hereof shall be referred to herein

as the "Merger Consideration."

<PAGE> 5

          (d)  As set forth below in Section 7.6, each holder of an option to

acquire ConQuest Common Stock shall be entitled to receive upon exercise of such

option after the Effective Time in lieu of ConQuest Common Stock, that number of

shares of Excalibur Common Stock as such person would have received in the

exchange set forth in Sections 3.1(a) and (b), if such person had exercised such

option immediately prior to the Effective Time.



     Section 3.2    Status of Securities After Effective Time.

          (a) From and after the Effective Time, and until surrendered and

exchanged, each outstanding certificate formerly representing shares of ConQuest

Common Stock shall be deemed for all purposes (other than the payment of

dividends or other distributions, if any, to shareholders of Excalibur) to

represent the right conferred upon such shares in accordance with Section 3.1

above to receive the number of whole shares of Excalibur Common Stock into which

such shares of ConQuest Common Stock are converted in the Merger. Upon surrender

and exchange of each outstanding certificate theretofore representing shares of

ConQuest Common Stock, there shall be paid to the record holders of the

certificate or certificates of Excalibur Common Stock issued in exchange

therefor the amount, without interest thereon, of dividends and other

distributions declared and paid to shareholders of record subsequent to the

Effective Time with respect to the number of whole shares of Excalibur Common

Stock represented thereby.



          (b) If any certificate evidencing Excalibur Common Stock is to be

registered in any name other than that in which the certificate surrendered in

exchange therefor is registered, it shall be a condition of such registration

that the certificate so surrendered shall be properly endorsed and otherwise in

<PAGE> 6

proper form for transfer as reasonably determined by Excalibur, that any

applicable securities laws are complied with, and that the person requesting

such exchange pay to Excalibur any transfer or other taxes required by reason of

the issuance of a certificate for shares of Excalibur Common Stock in any name

other than that of the registered holder of the certificate surrendered or

otherwise establish to the satisfaction of Excalibur that such tax has been paid

or is not payable by Excalibur.



          (c) From  and after the Effective Time, the stock transfer books of

ConQuest shall be closed and no transfer of shares of ConQuest Common Stock

shall be made.



     Section 3.3  Intentionally Omitted.





     Section 3.4 Dividends.  If Excalibur shall, at any time after the date

hereof but before the Effective Time, (i) issue a dividend in shares of

Excalibur Common Stock, (ii) combine the outstanding Excalibur Common Stock into

a smaller number of shares, (iii) subdivide the outstanding Excalibur Common

Stock, (iv) reclassify the Excalibur Common Stock, or (v) otherwise increase or

decrease the total number of shares of issued and outstanding capital stock of

Excalibur, then, in such event, the Merger Consideration to be delivered to

holders of ConQuest Common Stock who are entitled to receive Merger

Consideration in exchange for ConQuest Common Stock shall be adjusted so that

each shareholder shall be entitled to receive such Merger Consideration as such

shareholder would have been entitled to receive if the Effective Time had

occurred prior to the happening of such event (or, if applicable, the record

date in respect thereof).

<PAGE> 7

     Section 3.5 Closing.  The closing (the "Closing") of the transactions

contemplated by this Agreement shall take place at the offices of Holtzmann,

Stockholders will surrender to EAC the certificates theretofore representing all

of the shares of ConQuest Common Stock issued and outstanding at the Effective

Time, and EAC will deliver to the ConQuest Stockholders certificates

Stock theretofore represented by the certificates so surrendered shall have been

converted pursuant to the provisions of Section 3.1 (a) and (b) above.  The

ConQuest Common Stock certificates so surrendered will forthwith be canceled.



     Section 3.7 Legend on Certificates.  Each certificate representing

Excalibur Common Stock issued pursuant to this Agreement shall bear a legend

endorsed thereon in the form set forth below; provided that Excalibur shall

issue unlegended certificates in place of such legended certificates upon (i)

expiration of the applicable holding period then in effect under Rule 144

promulgated under the Securities Act of 1933, as amended, or (ii) transfer of

such shares pursuant to a registration of such shares pursuant to this Agreement

(including shares subject to the options described in Sections 7.6 below),

whichever occurs first:

          TRANSFER OF THE SHARES REPRESENTED HEREBY HAS NOT BEEN REGISTERED

          UNDER  THE  SECURITIES  ACT OF 1933 OR UNDER  ANY  SECURITIES  OR

          SIMILAR  LAWS OF ANY STATE.  THE SHARES MAY NOT BE SOLD,  OFFERED

          FOR  SALE, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF, IN  THE

with all requisite corporate power and authority to own, operate and lease its

properties and to carry on its business as it is now being conducted, and is

qualified or licensed to do business and is in good standing in each

jurisdiction in which the ownership or leasing of property by it or the conduct

of its business requires such licensing or qualification, except for such

failures to be so qualified or licensed which would not have a Material Adverse

Effect (as defined in Section 10.2 hereof) on Excalibur or any of its

subsidiaries.  Each of Excalibur and EAC has delivered to ConQuest true and

correct copies of its Certificate or Articles of Incorporation and By-laws as in

effect on the date hereof.

<PAGE> 9

authorized by Excalibur's Board of Directors and EAC's Board of Directors and

security holders, and no other corporate action or proceeding on the part of

Excalibur or Excalibur's security holders or EAC or EAC's security holders is

necessary for the execution, delivery and performance of this Agreement by

Excalibur and EAC and the consummation of the transactions contemplated hereby.

This Agreement has been duly and validly executed and delivered by Excalibur and

EAC and is a legal, valid and binding obligation of Excalibur and EAC,

enforceable against them in accordance with its terms except as enforceability

may be limited by bankruptcy, insolvency, reorganization, moratorium and other

similar laws relating to or affecting creditors rights generally, by general

equitable principles (regardless of whether such enforceability is considered in

a proceeding in equity or at law) and by any limitations on enforcement or

indemnification obligations in connection with the violation of laws as may be

required by public policy.



     Section 4.3 Capitalization of Excalibur.  As of the date hereof, Excalibur

and EAC have the authorized and outstanding capital stock and options set forth

on Schedule 4.3.  All outstanding Excalibur and EAC shares are duly authorized,

validly issued, fully paid and non-assessable, and are entitled to vote and have

other rights or other agreements or commitments providing for the issuance by

or any stock appreciation rights.  There are no voting trusts or other written

respects with the applicable requirements of the Securities Act and the Exchange

consistent basis, and present fairly the consolidated financial position,

results of operations and cash flows of Excalibur as of the dates and for the

periods indicated.  As at the date of each balance sheet of Excalibur included

in the Excalibur SEC Reports, Excalibur had no material liabilities or

obligations, contingent or otherwise, that are not reflected in such balance

sheet.



     Section 4.6  Absence of Certain Changes.  Except as described in Schedule

4.6, at no time between January 31, 1995 and the Closing shall Excalibur or any

of its subsidiaries have suffered any Material Adverse Effect, or taken, failed

exist after the date of this Agreement would constitute a breach of any of the

covenants set forth herein.

Securities Act, state securities laws, and the filing of Articles of Merger

pursuant to the Maryland Act, no filing or registration with, no notice to and

no permit, authorization, consent or approval of any public or governmental body

transactions contemplated by this Agreement or to enable Excalibur or any of its

subsidiaries to continue to conduct its business after the Effective Time in a

manner which is consistent with that in which it is presently conducted, except

where the failure to make such filing or to obtain such permit, authorization,

consent or approval will not have a Material Adverse Effect on Excalibur or any

of its subsidiaries or on ConQuest, and will not prevent consummation of the

transactions contemplated hereby.

<PAGE> 13

          (c) Neither the execution and delivery of this Agreement by Excalibur

or EAC, the performance by Excalibur and EAC of their obligations hereunder nor

the consummation by Excalibur and EAC of the transactions contemplated hereby

will (i) conflict with or result in any breach of any provision of the

indenture, license, agreement or other instrument or obligation to which

Excalibur or any of its subsidiaries is a party or by which any of them or any

of their properties or assets may be bound, or (iii) violate any order, writ,

issue, complaint, arbitration, inquiry, proceeding or investigation pending or,

to the knowledge of Excalibur or any of its subsidiaries, threatened against or

<PAGE> 14

administrative or governmental body, and there is no judgment, decree,

injunction, rule or order of any court, governmental department, commission,

Property Rights" means any and all rights to exclude existing from time to time

in the United States or any specified foreign jurisdiction under patent law,

copyright law, moral rights law, trade-secret law, semiconductor chip protection

law, trademark law, unfair competition law, or other similar rights.

          (a) Schedule 4.11 sets forth all Intellectual Property Rights owned by

Excalibur and its subsidiaries, including, but not limited, to all U.S. and

foreign trademarks, service marks, trade names, copyrights, U.S. and foreign

patents, patent applications and provisional specifications and applications,

reissues, divisionals, substitutes, continuations, and continuations-in-part

improvements, inventions, statistical data, development plans, technologies, and

manuals (both design and end-user), and all licenses or other proprietary rights

associated with any of the foregoing owned by Excalibur and its subsidiaries and

all applications for any of the foregoing (together with all related trade

secrets and know-how the "Excalibur Intellectual Property Rights").  The

Excalibur Intellectual Property rights, together with the intellectual property

rights licensed by Excalibur under agreements identified in Schedule 4.11 and

other information in the public domain constitute all of the intellectual

property necessary to enable Excalibur to conduct and to continue to conduct all

phases of its business (including products under development) in the manner

presently conducted or contemplated.  Excalibur and its subsidiaries have good

title to all of the Excalibur Intellectual Property Rights set forth in Schedule

4.11, free and clear of all liens, charges, encumbrances, licenses (exclusive or

nonexclusive) or grants of any other rights of any nature whatsoever, except as

set forth in Schedule 4.11.  Each of the Excalibur Intellectual Property Rights

is valid and enforceable, and the making, using, selling, reproductions in

copies thereof, preparation of derivative works based thereon, distribution of

copies by sale or other transfer of ownership, or otherwise, and the licensing

and sublicensing of others, to do any of the aforementioned acts with regard to

any of the products or works under such Excalibur Intellectual Property Rights

do not infringe any rights owned or held by any other person.



          (b)       To the best of Excalibur's and its subsidiaries' knowledge,

the conduct of the business of Excalibur and its subsidiaries as heretofore

carried on is free from any infringement of Intellectual Property Rights of

others and there is no pending, or to the best of Excalibur's knowledge,

threatened claim against Excalibur or EAC for any infringement of any of the
<PAGE> 16

foregoing.  Neither Excalibur, EAC nor, to their knowledge, any of their

respective employees or agents, has notified any person or entity that it

believes such person or entity is infringing, or making any preparation to

infringe, or contributing to or inducing others to infringe, any of the

Excalibur Intellectual Property Rights.



          (c)  Excalibur and its subsidiaries have taken all reasonable measures

to protect the secrecy, confidentiality and value of their respective trade

secrets and the Excalibur Intellectual Property Rights, and the same have not

been disclosed to others except pursuant to reasonable confidentiality

agreements.  All of the Excalibur Intellectual Property Rights subject to a

patent or copyright are presently valid and protectable and are not part of the

public knowledge, nor to Excalibur's and its subsidiaries' knowledge have they

been used, divulged or appropriated for the benefit of any past or present

employees or other persons, or to the detriment of Excalibur or its

subsidiaries.



          (d)  Excalibur and its subsidiaries, and to their knowledge, each

person associated in any way with the filing and prosecution of any application

for a patent or copyright relating to the Excalibur Intellectual Property Rights

have, throughout the prosecution of such application, acted in good faith before

the United States Patent and Trademark Office (the "Patent Office") or the

copyright office of the U.S. Library of Congress (the "Copyright Office"), as

the case may be, and all information provided by or on behalf of Excalibur or

any of its subsidiaries to the Patent Office and Copyright Office has been true

and correct in all material respects.

<PAGE> 17

          (e)  Other than the proceedings and challenges listed and identified

in Schedule 4.11 hereto, there is no pending or, to the knowledge of Excalibur

and its subsidiaries, threatened, action, suit or other proceeding before any

court, the United States Patent and Trademark Office, any foreign patent office,

arbitrator or federal or state administrative agency involving Excalibur (i)

that in any manner draws into question the validity or enforceability of any of

the Excalibur Intellectual Property Rights or alleges that the products, systems

or processes made or practiced with the Excalibur Intellectual Property Rights

infringed upon any patents, copyrights or other intellectual property rights of

others, (ii) in which there is a reasonable possibility of an adverse decision

or decisions which could otherwise prevent or have a Materially Adverse Effect

upon the right of Excalibur or any of its subsidiaries to use, sell or license

the Excalibur Intellectual Property Rights or (iii) in which Excalibur or its

subsidiaries or any of their respective agents is or was alleged to have

violated any legal restriction, including any competition law, with respect to

such Excalibur Intellectual Property Rights.



          (f)  The use of the trade names and trademarks listed on Schedule

4.11, if any, by Excalibur and its subsidiaries has been continuous, and such

names have never been abandoned by Excalibur or its subsidiaries.



          (g)  Except as shown on Schedule 4.11 hereto, neither Excalibur nor

any of its subsidiaries is aware of (i) any circumstances that would prevent,

delay or condition the issuance of a pending patent or copyright application

covering any of the Excalibur Intellectual Property Rights, or that would modify

or reduce the coverage of such patent or copyright as described in the

application therefor, a copy of which has been delivered to ConQuest (ii) any
<PAGE> 18

prior art with respect to any pending or issued patent or copyright or any of

the Excalibur Intellectual Property Rights, or (iii) any protest, objection or

challenge to any pending patent or copyright application covering the Excalibur

Intellectual Property Rights.



          (h)  Excalibur has delivered true and correct copies of each patent,

copyright registration  and application therefor to ConQuest.



     Section 4.12 Permits and Licenses.  Excalibur and each of its subsidiaries

has acquired and currently holds all permits, licenses, franchises,

authorizations, approvals and other certificates of authority as may be required

for Excalibur or its subsidiaries to conduct its business and the absence of

which would have a Material Adverse Effect on the business or operations of

Excalibur or any of its subsidiaries.  Excalibur and its subsidiaries are in

material compliance with all the terms thereof, and Excalibur is not aware of

any reason why any such permit, license, franchise, authorization, approval or

other certificates of authority could not be renewed on terms at least as

advantageous to Excalibur and its subsidiaries  as the current license,

franchise, authorization, approval and other certificates of authority held by

Excalibur or any of its subsidiaries.  Excalibur is not aware of any change in

any law, rule or regulation, whether or not yet effective, which is likely to

require Excalibur or any of its subsidiaries to obtain in the future any

additional license, franchise, authorization, approval or any other certificates

of authority, the absence of which would have a Material Adverse Effect on the

business or operations of Excalibur or any of its subsidiaries.

<PAGE> 19

     Section 4.13  Environmental Matters.  Neither Excalibur nor any of its

subsidiaries nor, to its knowledge, any other person, has (either with or

without negligence) caused or permitted the escape, disposal or release in

violation of applicable law of any biologically active or other hazardous

substances, or materials causing harm in or on any real property occupied or

the storage and use of such substances or materials.  Neither Excalibur nor any

of its subsidiaries has brought or allowed to be brought onto the Premises any

such materials or substances except to use in the ordinary course of Excalibur's

any of its subsidiaries or any lessee or sublessee or licensee of Excalibur or

any of its subsidiaries, Excalibur or EAC or such lessee, sublessee or licensee

have kept and maintained the Premises so as to be in material compliance with

<PAGE> 20

furnished or to be furnished by or on behalf of Excalibur or EAC pursuant to

subsidiaries are in compliance with all material contracts and agreements to

which Excalibur or any of its subsidiaries is a party or by which Excalibur or

any of its subsidiaries is bound (regardless of type of contract or annual sales

volume), and to the knowledge of Excalibur, no other party is in breach thereof.

Excalibur and EAC have provided to ConQuest true, correct and complete copies of

all minutes and/or consents of all actions taken by the shareholders and Board

of Directors of Excalibur and EAC since February 1, 1994.



     Section 4.16  Insurance.  Excalibur maintains insurance for the protection

of its business, properties and assets against such hazards and in such amounts

as is customary among businesses of like size and nature as Excalibur.  All such

insurance is in full force and effect, and Excalibur has neither received nor

given any notice of termination or reduction in coverage thereunder.



     Section 4.17  Certain Employment Matters; Labor Relations.  Except as set

forth in Schedule 4.17, there are no written employment or consulting agreements

or contracts in effect between Excalibur and any of its employees nor any oral

contracts or understandings of employment or consultation which are not

terminable upon the giving of notice not to exceed thirty (30) days.  Excalibur

has complied with all applicable laws, rules and regulations relating to the

employment of labor which could have a Material Adverse Effect on the business,

assets, condition or prospects, financial or otherwise, of Excalibur, including

without limitation those relating to wages, hours, collective bargaining, age

and sex discrimination and the payment and withholding of taxes; Excalibur has

withheld all amounts required by law or agreement to be withheld from the wages

anticipated between Excalibur and any employee or former employee.  None of the

employees of Excalibur are represented by a labor union, and no petition has

been filed or proceeding instituted of which Excalibur has notice by any

employee or group of employees with any labor relations boards seeking

recognition of a bargaining representative.  There is no dispute or controversy

with any union or other organization representing employees, and no arbitration

proceeding is pending or threatened involving such a dispute or controversy.



     Section 4.18  Employee Benefit Plans.

          (a)  Schedule 4.18 lists all Benefit Plans (as hereinafter defined),

and Excalibur has previously provided to ConQuest true and complete copies of

all qualified pension or profit sharing plans, any deferred compensation,

consultant, bonus or group insurance contract, or any other incentive, welfare,

or employee benefit plan or agreement maintained for the benefit of employees or

former employees of Excalibur (for purposes of this Section 4.18, the "Benefit

Plans"), together with (i) the most recent actuarial and financial reports

prepared with respect to any Benefit Plans, (ii) the most recent annual reports

filed with any government agency, and (iii) all rulings and determination

letters and any open requests for rulings or letters that pertain to any Benefit

Plan.  Excalibur has no commitment to create any such additional plans,

contracts or arrangements or to amend any such plans, contracts or arrangements

so as to increase, benefits thereunder.  Except as set forth in the employment

and consulting agreements set forth on Schedule 4.17, Excalibur is not obligated

to provide any post-retirement welfare benefits to its employees, including

post-retirement health or life insurance coverage.

<PAGE> 23

          (b)  To the best knowledge of Excalibur after reasonable investigation

and consultation with legal counsel, neither Excalibur nor any administrator or

fiduciary of any of such Benefit Plans (or agent or delegate of any of the

foregoing) has engaged in any transaction or acted or failed to act in any

manner which could subject Excalibur to any direct or indirect liability for a

breach of any fiduciary, co-fiduciary, or other duty under ERISA, which

individually or in the aggregate could result in a Material Adverse Effect to

Excalibur.  No oral or written representation or communication by Excalibur with

respect to any aspect of the Benefit Plans has been or will be made to employees

of Excalibur prior to the Effective Time which is not in accordance with the

written or otherwise preexisting terms and provisions of such Benefit plans in

effect immediately prior to the Effective Time.  There are no unresolved claims

or disputes under the terms of, or in connection with, the Benefit Plans and no

action, legal or otherwise, has been commenced with respect to any claim.



     Section 4.19  Property; etc.  Except for leased property and as specified

in such Schedule 4.19, and except for computers loaned to Excalibur for

development purposes, Excalibur has good, marketable and insurable title to all

of the property, real or personal, tangible or intangible, owned or used by it,

free and clear of all mortgages, pledges, liens, security interests or

encumbrances of any nature (other than liens for taxes, assessments or other

governmental charges not yet due and payable, or presently payable without

penalty or interest), (collectively, the "Encumbrances").  All machinery,

equipment, tools, furniture and fixtures owned or leased by Excalibur are in

good operating condition and repair.  There are no outstanding enforcement

actions or notices of violation issued or threatened by any federal, state,

county or municipal authority having jurisdiction over any such property.

<PAGE> 24

     Section 4.20  Tax Returns.  Excalibur and its subsidiaries have filed all

federal, state and other tax returns and reports required to be filed for all

periods on or before the due dates (as extended by any valid extensions of time)

and has paid all taxes shown to be due by said returns.  Such returns reflect

all taxes due and payable with respect to the periods covered thereby and there

are no liabilities, claims, interest or penalties pending, assessed, asserted or

threatened against Excalibur or any of its subsidiaries in connection with any

such taxes and no basis therefor.  The reserve, for taxes (federal, state and

local) reflected in Excalibur's balance sheet at January 31, 1995 are adequate

to cover any and all taxes, including deferred taxes, and any interest and

penalties in connection therewith which may be assessed with respect to the

property, business and operations of Excalibur up to the date of Excalibur's

balance sheet and all prior periods.  Excalibur has not been given or been

requested to give waivers of any statutes of limitations relating to the payment

of taxes for any taxable period.  Furthermore, to the best knowledge of

Excalibur, no fact exists which would constitute grounds for assessment of any

further tax liability.

     Section 4.21   Tax Free Status of Merger.  Excalibur and EAC acknowledge

that the Merger is intended to qualify as a "reorganization" within the meaning

of Section 368(a)(2)(D) of the Code and that the Merger is intended to be

pursuant to a "plan of reorganization" within the meaning of Section 354(a)(1)

of the Code.  Excalibur and EAC agree to report the Merger in accordance with

such intent for United States income tax purposes.  Excalibur represents that it

has and at the Closing will have no plan or intention to take any action and

covenants to take no action that would cause the Merger to fail to qualify as a

"reorganization" within the meaning of Section 368(a)(2)(D) of the Code,

<PAGE> 25

including but not limited to any action that would (i) cause or permit Excalibur

not to own directly stock of EAC possessing at least 80% of the total combined

voting power of all classes of stock entitled to vote and at least 80% of the

total number of shares of each other class of stock of EAC, (ii) cause or permit

EAC not to conduct the business carried on by ConQuest at the time of Closing or

not to use at least 50% of the assets owned by ConQuest at the time of Closing

and used at that time in connection with ConQuest's business in the business of

EAC, or (iii) cause or permit EAC to liquidate, merge into another corporation,

or otherwise transfer a substantial portion of its assets outside the ordinary

course of business.

                   REPRESENTATIONS AND WARRANTIES OF CONQUEST



     ConQuest represents and warrants to Excalibur and EAC as follows:



     Section 5.1  Corporate Organization and Good Standing.  ConQuest is a

corporation duly organized, validly existing and in good standing under the laws

of Maryland, with all requisite corporate power and authority to own, operate

and lease its properties and to carry on its business as it is now being

conducted, and, except as provided in Schedule 5.1 hereto, is qualified or

licensed to do business and is in good standing in each jurisdiction in which

the ownership or leasing of property by it or the conduct of its business

requires such licensing or qualification, except for such failures to be so

qualified or licensed which would not have a Material Adverse Effect on

ConQuest.  ConQuest has delivered to Excalibur true and correct copies of its

Articles of Incorporation and By-laws as in effect on the date hereof.

<PAGE> 26

     Section 5.2  Authorization; Binding Agreement.  ConQuest has all requisite

corporate power and authority to execute and deliver this Agreement and, subject

to the requisite approval of its stockholders, to perform its obligations

hereunder.  The execution, delivery and performance of this Agreement by

ConQuest, and the consummation by ConQuest of the transactions contemplated

hereby, have been duly authorized by ConQuest's Board of Directors and no other

corporate action or proceeding on the part of ConQuest is necessary for the

execution, delivery and performance of this Agreement by ConQuest and the

consummation of the transactions contemplated hereby except for obtaining the

requisite approval of ConQuest's shareholders.  This Agreement has been duly and

validly executed and delivered by ConQuest and is a legal, valid and binding

obligation of ConQuest, enforceable against it in accordance with its terms

except as enforceability may be limited by bankruptcy, insolvency,

reorganization, moratorium and other similar laws relating to or affecting

creditors' rights generally, by general equitable principles (regardless of

whether such enforceability is considered in a proceeding in equity or at law)

and by any limitations or enforcement or indemnification obligations in

connection with the violation of laws as may be required by public policy.



     Section 5.3  Capitalization of ConQuest.  As of the date hereof, the

authorized capital stock of ConQuest consists of 2,500,000 shares of ConQuest

Common Stock, without par value.  As of the date hereof, there were issued and

outstanding 1,478,287 shares of ConQuest Common Stock.  All of the outstanding

shares of ConQuest Common Stock have been duly authorized and validly issued,

were not issued in violation of any person's preemptive rights and are fully

paid and nonassessable.  As of the date hereof, options to acquire 593,122

shares of ConQuest Common Stock were issued and outstanding under ConQuest's
<PAGE> 27

stock option plan.  As of the date hereof, except as set forth above or in

Schedule 5.3 hereof, there are no outstanding options, warrants, subscriptions,

conversion rights or other rights, agreements or commitments obligating ConQuest

or any of its subsidiaries to issue any additional shares of the capital stock

of ConQuest or any other securities convertible into, exchangeable for or

evidencing the right to subscribe for or acquire from ConQuest any shares of the

capital stock of ConQuest, or any stock appreciation rights.  Except as set

forth in Schedule 5.3, as of the date hereof, to the knowledge of ConQuest there

are no voting agreements, voting trusts or other restrictions on the transfer of

the shares of the capital stock of ConQuest or limiting the voting rights of any

such shares, except for customary restrictions imposed by federal and state

securities laws.



     Section 5.4  Subsidiaries; Other Transactions.  Except as set forth in

Schedule 5.4 hereof, there are no subsidiaries of ConQuest.  Schedule 5.4 sets

forth the issued and outstanding securities of each of its subsidiaries as of

the date hereof and the number of such shares thereof which are owned by

ConQuest.  Other than as set forth in Schedule 5.4, ConQuest does not own

directly or indirectly, any capital stock or other equity securities of any

corporation or have any direct or indirect equity or ownership interest in any

other business.  As of the date of this Agreement, except as set forth on

Schedule 5.4, ConQuest has no obligations or commitments to, and does not

presently contemplate that it will, within the foreseeable future,  invest any

funds in any business or entity or engage in any merger, consolidation,

reorganization, sale of assets or sale or purchase of securities or any similar

transaction with any business or entity other than as set forth in Schedule 5.4.

<PAGE> 28

     Section 5.5  Financial Statements.  Schedule 5.5 consists of the Balance

Sheet of ConQuest as of December 31, 1994 and a Statement of Operations and

Stockholders Deficit and Changes in Cash Flows for the  year ended December

31,1994, as audited by Arthur Andersen LLP (the "Audited Statements") and the

unaudited Balance Sheet of ConQuest as of April 30, 1995 and a Statement of

Operations  and Stockholders Deficit and Changes in Cash Flows for the four

month period ended April 30, 1995 (the "Unaudited Statements").  The Audited

Statements and the footnotes thereto fairly present the financial condition of

ConQuest at December 31, 1994, and the results of operations of ConQuest for the

year then ended, and have been prepared in accordance with generally accepted

accounting principles consistently applied.  At December 31, 1994 and April 30,

1995, ConQuest had no liabilities or obligations of any kind, contingent or

otherwise, which are not reflected in the Audited Statements and the Unaudited

Statements or the footnotes thereto, other than as to the Unaudited Statements,

any deferred revenue.



     Section 5.6  Absence of Certain Changes.  Since December 31, 1994, except

as set forth on Schedule 5.6 ConQuest has not and prior to Closing shall not

have suffered any Material Adverse Effect or taken, failed to take or suffered

to exist any action that if taken, not taken or suffered to exist after the date

of this Agreement would constitute a breach of any of the covenants set forth

herein.



     Section 5.7  Certain Fees.  Except as provided on Schedule 5.7 hereto,

neither ConQuest, nor any of their officers, directors, employees or agents has

employed any broker or finder or incurred any liability for any financial

advisory, brokerage or finder's fee or commissions in connection with the

transactions contemplated herein.  No other agent or broker or other person is
<PAGE> 29

entitled to any commission or finder's fee in connection with the transaction

contemplated by this Agreement.



     Section 5.8  Consents and Approvals; No Violations.

          (a)  To the knowledge of ConQuest, ConQuest is not in violation of any

applicable law, statute, ordinance, order, rule or regulation promulgated or

judgment, decree, order, concession, grant, permit, license or other

governmental authorization or approval, issued or entered by, any federal, state

or local, United States or foreign, court or governmental authority relating to

or affecting the operation, conduct or ownership of the property or business of

ConQuest, which violation or violations could, individually or in the aggregate,

have a Material Adverse Effect on ConQuest.



          (b)  Except for applicable requirements of the Exchange Act, the

Securities Act, state securities laws, and the filing of Articles of Merger

pursuant to the Maryland Act, no filing or registration with, no notice to and

no permit, authorization, consent or approval of any public or governmental body

or authority is necessary for the consummation by ConQuest of the transactions

contemplated by this Agreement or to enable ConQuest to continue to conduct its

business after the Effective Time in a manner which is consistent with that in

which it is presently conducted, except where the failure to make such filing or

to obtain such permit, authorization, consent or approval will not have a

Material Adverse Effect on ConQuest, or on Excalibur or EAC and will not prevent

consummation of the transactions contemplated hereby.

<PAGE> 30

          (c) Neither the execution and delivery of this Agreement by ConQuest,

the performance by ConQuest of its obligations hereunder nor the consummation by

ConQuest of the transactions contemplated hereby will (i) conflict with or

result in any breach of any provision of the Articles of Incorporation or By-

laws of ConQuest, (ii) except as set forth on Schedule 5.8(c) hereto, result in

a violation or breach of, or constitute (with or without due notice or lapse of

time or the happening or occurrence of any other event) a default by ConQuest,

or permit the termination of, or require the consent of any other party to, or

result in the acceleration of, or entitle any party to accelerate (whether as a

result of a change in control of ConQuest or otherwise) (or give rise to the

creation of any lien, charge, security interest or encumbrance upon any

properties or assets of ConQuest) under, any of the terms, conditions or

provisions of any contract, note, bond, mortgage, indenture, license, agreement

or other instrument or obligation to which ConQuest is a party or by which it or

any of its properties or assets may be bound or (iii) violate any order, writ,

injunction, decree, statute, rule or regulation of any court or governmental

authority applicable to ConQuest, or any of its properties or assets.



     Section 5.9  Litigation.  There is no action, suit, set of related actions

or suits concerning a common issue, complaint, arbitration, inquiry, proceeding

or investigation pending or, to the knowledge of ConQuest, threatened against or

involving ConQuest, or any properties or rights of ConQuest, before any court,

arbitrator or administrative or governmental body, and there is no judgment,

decree, injunction, rule or order of any court, governmental department,

commission, agency, instrumentality or arbitrator outstanding against ConQuest

which would individually or in the aggregate, if adversely determined, have a

Material Adverse Effect on ConQuest.  As of the date hereof, there are no

actions, suits or proceedings pending or, to the knowledge of ConQuest,
<PAGE> 31

threatened against ConQuest arising out of or in any way related to this

Agreement, the Merger or any of the transactions contemplated hereby or thereby.



     Section 5.10  Certain Employment Matters; Labor Relations.  Except as set

forth in Schedule 5.10(a), there are no written employment or consulting

agreements or contracts in effect between ConQuest and any of its employees nor

any oral contracts or understandings of employment or consultation which are not

terminable upon the giving of notice not to exceed thirty (30) days.  Except as

set forth on Schedule 5.10(b):  ConQuest has complied with all applicable laws,

rules and regulations relating to the employment of labor which could have a

Material Adverse Effect on the business, assets, condition or prospects,

financial or otherwise, of ConQuest, including without limitation those relating

to wages, hours, collective bargaining, age and sex discrimination and the

payment and withholding of taxes; ConQuest has withheld all amounts required by

law or agreement to be withheld from the wages or salaries of their employees;

and ConQuest has no unaccrued liability for any arrears of wages or any taxes or

penalties for failure to comply with any of the foregoing.  Except as set forth

in Schedule 5.10(a), there are no controversies pending, threatened or

reasonably anticipated between ConQuest and any employee or former employee.

None of the employees of ConQuest are represented by a labor union, and no

petition has been filed or proceeding instituted of which ConQuest has notice by

any employee or group of employees with any labor relations boards seeking

recognition of a bargaining representative.  There is no dispute or controversy

with any union or other organization representing employees, and no arbitration

proceeding is pending or threatened involving such a dispute or controversy.

<PAGE> 32

     Section 5.11  Employee Benefit Plans.

          (a)  Schedule 5.11(a) lists all Benefit Plans (as hereinafter

defined), and ConQuest has previously provided to Excalibur true and complete

copies of all qualified pension or profit sharing plans, any deferred

compensation, consultant, bonus or group insurance contract, or any other

incentive, welfare, or employee benefit plan or agreement maintained for the

benefit of employees or former employees of ConQuest (for purposes of this

Section 5.11, the "Benefit Plans"), together with (i) the most recent actuarial

and financial reports prepared with respect to any Benefit Plans, (ii) the most

recent annual reports filed with any government agency, and (iii) all rulings

and determination letters and any open requests for rulings or letters that

pertain to any Benefit Plan.  ConQuest has no commitment to create any such

additional plans, contracts or arrangements or to amend any such plans,

contracts or arrangements so as to increase, benefits thereunder.  Except as set

forth in the employment and consulting agreements set forth on Schedule 5.10(a),

ConQuest is not obligated to provide any post-retirement welfare benefits to its

employees, including post-retirement health or life insurance coverage.



          (b)  Except as provided under Schedule 5.11(b) hereto, to the best

knowledge of ConQuest after reasonable investigation and consultation with legal

counsel, neither ConQuest nor any administrator or fiduciary of any of such

Benefit Plans (or agent or delegate of any of the foregoing) has engaged in any

transaction or acted or failed to act in any manner which could subject ConQuest

to any direct or indirect liability for a breach of any fiduciary, co-fiduciary,

or other duty under ERISA, which individually or in the aggregate could result

in a Material Adverse Effect to ConQuest.  No oral or written representation or

communication by ConQuest with respect to any aspect of the Benefit Plans has

been or will be made to employees of ConQuest prior to the Effective Time which
<PAGE> 33

is not in accordance with the written or otherwise preexisting terms and

provisions of such Benefit Plans in effect immediately prior to the Effective

Time.  Except as disclosed on Schedule 5.11(b) hereto, there are no unresolved

claims or disputes under the terms of, or in connection with, the Benefit Plans

and no action, legal or otherwise, has been commenced with respect to any claim.



     Section 5.12  Property; etc.  Except for leased property and as specified

in such Schedule 5.12, ConQuest has good, marketable and insurable title to all

of the property, real or personal, tangible or intangible, owned or used by it,

free and clear of all mortgages, pledges, liens, security interests or

encumbrances of any nature (other than liens for taxes, assessments or other

governmental charges not yet due and payable, or presently payable without

penalty or interest), (collectively, the "Encumbrances").  All machinery,

equipment, tools, furniture and fixtures owned or leased by ConQuest are in good

operating condition and repair.  There are no outstanding enforcement actions or

notices of violation issued or threatened by any Federal, state, county or

municipal authority having jurisdiction over any such property.



     Section 5.13  Vote.  The affirmative vote of two-thirds of the votes that

holders of the outstanding shares of ConQuest Common Stock, voting together as a

class, are entitled to cast is the only vote of the holders of ConQuest's

capital stock necessary to approve this agreement and the Articles of Merger and

the transactions contemplated hereby.



     Section 5.14  Tax Returns.  Except as disclosed on Schedule 5.14 hereto,

ConQuest has filed all federal, state and other tax returns and reports required

to be filed for all periods on or before the due dates (as extended by any valid
<PAGE> 34

extensions of time) and has paid all taxes shown to be due by said returns.

Such returns reflect all taxes due and payable with respect to the periods

covered thereby and there are no liabilities, claims, interest or penalties

pending, assessed, asserted or threatened against ConQuest in connection with

any such taxes and no basis therefor.  The reserves for taxes (federal, state

and local) including payroll and employment related taxes reflected in

ConQuest's balance sheet at December 31, 1994 are adequate to cover any and all

taxes, including deferred taxes, and any interest and penalties in connection

therewith which may be assessed with respect to the property, business and

operations of ConQuest up to the date of ConQuest's balance sheet and all prior

periods.  ConQuest has not been given or been requested to give waivers of any

statutes of limitations relating to the payment of taxes for any taxable period.

Furthermore, to the best knowledge of ConQuest, no fact exists which would

constitute grounds for assessment of any further tax liability.



     Section 5.15  Intellectual Property.  As used herein, "Intellectual

Property Rights" means any and all rights to exclude existing from time to time

in the United States or any specified foreign jurisdiction under patent law,

copyright law, moral rights law, trade-secret law, semiconductor chip protection

law, trademark law, unfair competition law, or other similar rights.

          (a) Schedule 5.15 sets forth all Intellectual Property Rights owned by

ConQuest, including, but not limited to, all U.S. and foreign trademarks,

service marks, trade names, copyrights, U.S. and foreign patents, patent

applications and provisional specifications and applications, reissues,

divisionals, substitutes, continuations, and continuations-in-part thereof,

utility models, design patents and applications therefore, computer programs and

computer software, proprietary information, relating to products, processes

therefore, apparatus and maintenance thereof, research, computer software,
<PAGE> 35

manufacturing techniques, program files, flow charts, drawings, techniques,

source and executable codes, standards, specifications, improvements,

inventions, statistical data, development plans, technologies, and manuals (both

design and end-user), and all licenses or other proprietary rights associated

with any of the foregoing owned by ConQuest and all applications for any of the

foregoing (together with all related trade secrets and know-how the "ConQuest

Intellectual Property Rights").  The ConQuest Intellectual Property rights,

together with the intellectual property rights licensed by ConQuest under

agreements identified in Schedule 5.15 and other information in the public

domain constitute all of the intellectual property necessary to enable ConQuest

to conduct and to continue to conduct all phases of its business (including

products under development) in the manner presently conducted or contemplated.

ConQuest has good title to all of the ConQuest Intellectual Property Rights set

forth in Schedule 5.15, free and clear of all liens, charges, encumbrances,

licenses (exclusive or nonexclusive) or grants of any other rights of any nature

whatsoever, except as set forth in Schedule 5.15.  Each of the ConQuest

Intellectual Property Rights is valid and enforceable, and the making, using,

selling, reproductions in copies thereof, preparation of derivative works based

thereon, distribution of copies by sale or other transfer of ownership, or

otherwise, and the licensing and sublicensing of others, to do any of the

aforementioned acts with regard to any of the products or works under such

ConQuest Intellectual Property Rights do not infringe any rights owned or held

by any other person.



          (b)  To the best of ConQuest's knowledge, the conduct of the business

of ConQuest carried on is free from any infringement of Intellectual Property

Rights of others and there is no pending, or to the best of ConQuest's

knowledge, threatened claim against ConQuest for any infringement of any of the
<PAGE> 36

foregoing.  Neither ConQuest, nor to its knowledge, any of their respective

employees or agents, has notified any person or entity that it believes such

person or entity is infringing, or making any preparation to infringe, or

contributing to or inducing others to infringe, any of the ConQuest Intellectual

Property Rights.



          (c)  ConQuest has taken all reasonable measures to protect the

secrecy, confidentiality and value of its trade secrets and the ConQuest

Intellectual Property Rights, and the same have not been disclosed to others

except pursuant to reasonable confidentiality agreements.  All of the ConQuest

Intellectual Property Rights subject to a patent or copyright are presently

valid and protectable and are not part of the public knowledge, nor to

ConQuest's knowledge have they been used, divulged or appropriated for the

benefit of any past or present employees or other persons, or to the detriment

of ConQuest.



          (d)  ConQuest, and to its knowledge, each person associated in any way

with the filing and prosecution of any application for a patent or copyright

relating to the ConQuest Intellectual Property Rights have, throughout the

prosecution of such application, acted in good faith before the United Sates

Patent and Trademark Office (the "Patent Office") or the Copyright Office, as

the case may be, and all information provided by or on behalf of ConQuest to the

Patent Office and Copyright Office has been true and correction all material

such substances or materials on or about the CQ Premises in any manner not

sanctioned by law or by commercially reasonable standards in the industry for

          (c)  Each of the parties hereby agrees that it will use its best

efforts and will cause its respective subsidiaries and other "affiliates"

(defined in accordance with Rule 145 promulgated under the Securities Act (each

such person being referred to as an "Affiliate")) to use their respective best

efforts to cause the business combination to be effected by the Merger to be

accounted for as a pooling of interests, not to take any action inconsistent

     Section 7.6  Stock Options and Acquisition Rights.

          (a)  Schedule 7.6 sets forth all options and other rights to acquire

ConQuest Common Stock ("Option") setting forth the holder of each Option, the

exercise price, vesting schedule and term thereof.  Pursuant to this Agreement,

each holder of an outstanding Option shall be entitled to receive upon exercise

of such Option after the Effective Time in lieu of ConQuest Common Stock, for

each share of ConQuest Common Stock subject to such Option, for the same

aggregate exercise price of the Option, that number of shares of Excalibur

Common Stock as such person would have received in the exchange provided in

Section 3.1(a) and (b) hereof, if such person had exercised the Option

immediately prior to the Effective Time (subject to Section 7.6(b) below), and

on such terms as nearly identical as the terms of the Option as permitted by

applicable securities and tax laws including, without limitation, any vesting

schedule, or, if not so permitted, consistent with the terms of the option plans

of Excalibur (except that any Option exercise period shall not be extended

beyond the original termination date except as provided below and the number of

shares of Excalibur Common Stock issuable upon exercise of the option shall be

rounded down to the nearest whole number of shares and neither Excalibur nor EAC

shall be obligated to pay the Option holder for any fractional options which

shall lapse).  Upon approval of this Agreement by the shareholders of ConQuest,
<PAGE> 52

the shareholders of ConQuest shall be deemed to have adopted and approved an

amendment to the stock option plans of ConQuest to change the stock issued

pursuant to such plans to Excalibur Common Stock after the Effective Time.

Nothing contained in this Section 7.6 or elsewhere in this Agreement shall be

construed to, or have the effect of, changing the date upon which any option was

issued by ConQuest or the period of time for which any option holder shall be

deemed to have held any option, for purposes of vesting, option expiration or

for any other purpose.



          (b)  If, after the Effective Time, the number of outstanding shares of

Excalibur Common Stock are increased or decreased or changed into or exchanged

for a different number or kind of shares or other securities of Excalibur or of

another corporation, by reason of any stock split, stock dividend,

reorganization, merger, consolidation, recapitalization or reclassification, an

appropriate adjustment in the number and kind of shares issuable upon exercise

of any Options outstanding as of the Effective Date and as of the date of such

increase, decrease, change or exchange, or the unexercised portion of such

options, shall be made.  The foregoing adjustment shall be made without any

change in the total exercise price applicable to the Option or unexercised

portion thereof, and shall be made in such a manner so that the stock options

designated as Qualified Stock Options continue to qualify under Section 422 of

the Code.



     Section 7.7  Excalibur Options.  Excalibur hereby agrees to issue 324,151

stock options to purchase shares of Excalibur Common Stock to the ConQuest

employees set forth on Schedule 7.7 in the amounts set forth opposite their

names pursuant to a new Excalibur Stock Option Plan which has been approved by
<PAGE> 53

Excalibur's Board of Directors.  Subject to the limits required by Section 422

of the Code, and the stockholder approval as described below, the stock options

shall be Qualified Stock Options (within the meaning of Section 422 of the

Code); if stockholder approval is not obtained as provided under Section 422 of

the Code, the options issued under the Plan will constitute non-qualified stock

options.  Each option shall have a term of ten years, will vest in equal 12.5%

increments every six months and will have an exercise price equal to the average

closing price of Excalibur Common Stock during the ten trading days prior to the

Effective Time.  The options will be issued within ten days after the Effective

Time.  Excalibur agrees to hold a meeting of its stockholders upon the earlier

to occur of (i) Excalibur's next annual meeting of stockholders, and (ii) nine

months after the Effective Time, at which meeting Excalibur's Board will

recommend that Excalibur's stockholders approve the foregoing Stock Option Plan.

The shares issuable upon exercise of these options will be registered two years

after the date of the Closing.



     Section 7.8  Employment Agreements Excalibur shall enter into employment

agreements with Messrs. Edwin Addison, Paul Nelson, John McGrath and Donald

Wilson in the forms set forth in Exhibit 7.8.

the Effective Date, Excalibur shall cause to be paid in full the liabilities

listed on Schedule 7.9 hereto.

<PAGE> 54

     Section 7.10  Registration Rights.

          (a)  Excalibur shall prepare and file with the Securities and Exchange

the date when Excalibur files its Form 8-K including combined financial

1996.  Excalibur will use its reasonable best efforts to cause such registration

statement to become effective no later than March 1, 1997.

Section 7.11.

the Disclosing Party, its officers, directors, employees or agents or otherwise,

irrespective of the form of communication of such Confidential Material, and

whether furnished before or after the date  of this Agreement "Confidential

confidentiality agreement with or other contractual, legal or fiduciary

obligation of confidentiality to the Disclosing Party or any other party with

competing with the Disclosing Party, providing the information to a competitor

of the Disclosing Party or for any other purpose.  Each party, as a Receiving

Party, further agrees that the Confidential Material will be kept confidential

and that neither it nor any of its officers, directors, employees or agents will

disclose any of the Confidential Material of the Disclosing Party in any manner

whatsoever; provided, however, that each party (i) may make any disclosure of

such information as to which the Disclosing Party gives its prior written

consent and (ii) any of such information may be disclosed to the officers,

directors, employees and agents of a Receiving Party who need to know such

information for the purposes consistent with this Agreement and the transactions

contemplated hereby and who agree to keep such information confidential and who

are provided with a copy of this Section 7.11 and agree to be bound by the terms

hereof to the same extent as if they were parties hereto.

          (c)  Each of the parties hereto, as a Receiving Party shall be

responsible for any breach of this Section 7.11 by any of its officers,

directors, employees and agents and agrees, at such party's sole expense, to

take all reasonable measures to restrain its officers, directors, employees and

agents from prohibited or unauthorized disclosure or use of the Confidential

Material.

          (d)  In the event that a Receiving Party or any of its officers,

directors, employees or agents is requested or required (by oral questions,

interrogatories, requests for information or documents in legal proceedings,

subpoena, civil investigative demand or other similar process) to disclose any

of the Confidential Material, such party shall provide the Disclosing Party with

prompt written notice of any such request or requirement so that the Disclosing

Party may seek a protective order or other appropriate remedy and/or waive

compliance with the provisions of this Section 7.11.  If, in the absence of a

protective order or other remedy or the receipt of a wavier by the Disclosing
<PAGE> 57

party, a Receiving Party or any of its officers, directors, employees or agents

is nonetheless legally compelled to disclose the Confidential Material to any

tribunal, regulatory authority, or agency, the Receiving Party or its officers,

directors, employees or agents may, without liability hereunder, disclose to

such tribunal, regulatory authority or agency only that portion of the

Confidential Material which is legally required to be disclosed, provided that

the Receiving Party exercises its best efforts to preserve the confidentiality

of the Confidential Material.

          (e)  In the event that the Merger does not occur, each party, as a

Receiving Party, will and will cause its respective officers, directors,

employees and agents to promptly deliver to the Disclosing Party all documents

(and all copies thereof) furnished to it or its officers, directors, employees

or agents by or on behalf of the Disclosing Party.   All other Confidential

Material not returned to the Disclosing Party, including all Confidential

Material prepared by a Receiving Party or its officers, directors, employees or

agents with respect to the Disclosing Party, shall be destroyed and no copy

thereof shall be retained and, upon request, the Receiving Party shall certify

in writing to the Disclosing Party that such action has been taken.

Notwithstanding the return or destruction of the Confidential Material, the

Receiving Party, its officers, directors, employees and agents will continue to

be bound by the obligations of confidentiality and other obligations hereunder

for a period of two (2) years from the later of the date of this Agreement or

the Effective Time.

          (f)  Each of the parties hereto recognizes and acknowledges the

competitive value and confidential nature of the Confidential Material and the

damage that could result to a Disclosing Party if information contained therein

is disclosed to any third party.  In view of the nature of the Confidential

Material, each of the parties agrees that any unauthorized disclosure of the
<PAGE> 58

Confidential Material or other violation, or threatened violation, of this

Section 7.11 would cause irreparable damage to the Disclosing Party and that,

therefore, the Disclosing Party shall be entitled to an injunction prohibiting

the Receiving Party from any such disclosure, attempted disclosure, violation or

threatened violation of this Section 7.11, and each party further agrees to

waive, and to cause its officers, directors, employees and agents to waive, any

requirement for the securing or posting of any bond in connection with such

remedy.  Such remedies shall not be in addition to all other remedies available

at law or equity to the Disclosing Party.



     Section 7.12   Excalibur Employee Benefit Plans.

          (a)  After the Effective Time, all Excalibur employees who had

formerly been employees of ConQuest shall be entitled to all of the employee

benefit plans and agreements presently or hereafter maintained or adopted for

the benefit of Excalibur employees, including, without limitation, the Benefit

Plans listed on Schedule 4.18 hereto, and for purposes thereof, each such former

ConQuest employee shall be deemed to have been employed by Excalibur beginning

on the date that he or she became employed by ConQuest.



          (b)  After the Effective Time, a committee shall be formed to evaluate

employee compensation policies and employee benefit plans heretofore maintained

by ConQuest and Excalibur, which committee shall make recommendations to the

Excalibur Board of Directors regarding the continuance, discontinuance or

adoption of such plans and policies and related transitional matters.  Pat Condo

and Ed Addison (or the ConQuest Representative in his absence) shall serve as

the sole members of the committee.

<PAGE> 59

     Section 7.13   ConQuest Stockholder Representative.  Excalibur shall deal

exclusively with the Stockholder Representatives (as defined in Section 8.2(i)

below), and their successors and assigns, who are appointed by the ConQuest

stockholders under the Transmittal Letters (as defined in Section 8.2(i) below)

to act on behalf of such ConQuest Stockholders in connection with such matters

as may be described in the Transmittal Letters.  Such Stockholder

Representatives shall have authority to act for all of the ConQuest Stockholders

and Excalibur shall rely on the Stockholder Representative to speak for each and

every ConQuest Stockholder.

parties hereto.

other acts of the other parties hereto, (b) waive any inaccuracies in the

deemed amended as of the date of this Agreement to include such disclosure, as

well as any other information disclosed to or discovered by the party to whom
