Red Bank, New Jersey 07701

Gentlemen:

Conolog
Corporation (the Company) proposes to offer for sale (the Offering) in a
private offering pursuant to Regulation D promulgated under the Securities Act
of 1933, as amended (the Act) (i) up to One Million Dollars ($l,000,000) of
convertible debentures convertible into shares of common stock (Convertible
Debentures); (ii) common stock warrants (the Warrants); and (iii) Class B
warrants (Class B Warrants) exercisable for 36 months into the Convertible
Debentures (collectively, the Securities). Offers and sales of the Securities
shall be to Accredited Investors (as defined in Regulation D promulgated by the
Securities and Exchange Commission) or qualified institutional buyers as
defined under Rule 144A. This letter agreement shall confirm our agreement concerning
Garden State Securities, Inc. acting as exclusive selling or placement agent
(the Selling Agent or GSS)) in connection with the sale of the Securities.

1.
Appointment of Selling Agent.

On
the basis of the representations and warranties contained herein, and subject
to the terms and conditions set forth herein, the Company hereby appoints
Garden State Securities, Inc.. as exclusive selling agent/placement agent for a
period beginning on the date hereof and terminating on August 31, 2009 (unless
terminated sooner pursuant to the terms hereof) and grants to GSS the right to
offer, as its agent, the Securities pursuant to the terms of this Agreement.
However, GSS will be compensated directly from the Company within 1 business
day of the receipt of the proceeds from any exercise of the Class B Warrants
based on the amount of gross proceeds received by the Company from investors
upon the exercise of the Class B Warrants and such compensation shall survive
the termination of the Offering. On the basis of such representations and
warranties, and subject to such conditions, GSS hereby accepts such appointment
and agree to use its reasonable best efforts to secure subscriptions to
purchase subscriptions for the Securities. The Company understands that the
Selling Agent is being retained to obtain subscriptions on a best efforts
basis and has not guaranteed the sale of any Securities.

2.
Terms of the Offering.

(a)
The Offering shall consist of (i) Convertible Debentures; (ii) Warrants; and
(iii) Class B Warrants. The Offering is being made on a best efforts basis
with no minimum offering amount of subscriptions, and the parties shall use
their reasonable efforts to consummate a closing of subscriptions prior to
August 31, 2009. In the event a subscription is not accepted, such rejected
subscription funds will be returned to the subscriber without interest or
deduction.

(b)
The Company has prepared a subscription agreement (the Securities Purchase
Agreement) and form of Warrant and form of Class B Warrant to be delivered to
all

prospective investors. The Securities Purchase
Agreement, and form of Warrant and Class B Warrants, including all supplements,
exhibits and appendices thereto and documents delivered therewith, are referred
to herein as the Documents and shall include any supplements or amendments in
accordance with this Agreement. The Offering shall commence on the date hereof,
and shall expire at 5:00 p.m., New York time, on August 31, 2009, unless
extended as provided above. Such period, as same may be so extended, shall
hereinafter be referred to as the Offering Period.

(c) Each prospective investor (Prospective Investor) who desires to purchase
Securities shall deliver, in immediately available funds in the amount
necessary to purchase the amount of Securities such Prospective Investor
desires to purchase, to Grushko & Mittman, P.C. as Escrow Agent (the
Escrow Agent), in accordance with the wire transfer instructions set forth in
the Escrow Agreement between the Company, the Escrow Agent and the Prospective
Investor. The Prospective Investor shall also deliver their executed Securities
Purchase Agreement to the Selling Agent for delivery to the Escrow Agent. The
Selling Agent shall not have any obligation to independently verify the
accuracy or completeness of any information contained in any Purchase Agreement
or the authenticity, sufficiency, or validity of any check delivered by any
Prospective Investor in payment for Securities. Purchasers in the Offering
shall be accredited investors or qualified Institutions as determined in
accordance with Regulation D.

3.

the Securities Purchase Agreement have been satisfied. References herein to the
actual closing date thereof shall be referred to as a Closing Date.

6.

(a)
The Company represents and warrants to, and agrees with, the Selling Agent
that:

(i)
No Documents or information provided by the Company to Prospective Investors,
including, without limitation the SEC Reports (as defined in the Purchase
Agreement), shall contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein in light of circumstances made therein not misleading.

(ii)
The Company is, and at all times during the period from the date hereof to and
including each Closing Date will be, a corporation duly organized, validly
existing, and in good standing under the laws of the State of Delaware, with
full corporate power and authority, and has obtained all necessary consents,
authorizations, approvals, orders, licenses, certificates, and permits and
declarations of and from, and has made filings with, all federal, state and
local authorities, to own, lease, license, and use its properties and assets
and to conduct its business as presently conducted and/or in any such case
where the failure to have any of the foregoing would not have a material
adverse effect on the Companys presently conducted business. As of the date
hereof, the Company is, and at all times during the period from the date hereof
to and including each Closing Date, duly qualified to do business and is in
good standing in every jurisdiction in which its ownership, leasing, licensing,
or use of property and assets or the conduct of its business makes such
qualification necessary except where the failure to be so qualified would not
have a material adverse effect on the Companys business.

(iii)
As of the date hereof, except as disclosed in the Securities Purchase
Agreement, there is no, and as of each Closing Date there shall not be any,
litigation, arbitration, claim, governmental or other proceeding (formal or
informal), or investigation pending or to the Companys knowledge threatened,
with respect to the Company, or its respective operations, businesses, properties,
or assets, except as properly described in the Purchase Agreement or such as

have a material adverse effect upon the operations, business, properties, or
assets of the Company.

The Company is not in violation or breach of, or in default with respect to,
any term of its Certificate of Incorporation or By-Laws.

the transactions contemplated hereby and thereby.

(vi)
The Securities and the Selling Agents Warrants, when issued and delivered to
the Prospective Investor pursuant to the terms of the Offering shall be duly
authorized, validly issued, fully paid and non-assessable, without any personal

shall not have been issued in violation of any preemptive rights of
stockholders.

Neither the Company nor any of its officers, directors, or affiliates, has
engaged or will engage, directly or indirectly, in any act or activity that may

8.

The
obligations of the Selling Agent pursuant to this Agreement shall be subject,
in its discretion, to the continuing accuracy of the representations and
warranties of the Company contained herein and in each certificate and document
contemplated under this Agreement to be delivered to the Selling Agent, as of
the date hereof and as of each Closing Date, with respect to the performance by
the Company of its obligations hereunder, and to the following conditions:

the Securities shall be satisfactory in form and
substance to GSS and the Company.

9.
Termination.

This
Agreement may be terminated by the Selling Agent (i) at anytime in the event
the Selling Agent has determined, in good faith, that the Documents fail to
contain a material fact required to be stated therein or necessary to make the
statements therein not misleading or (ii) upon three days written notice. The
Company may not terminate this Agreement in the absence of a material breach of
any covenant, representation or warranty contained in this Agreement made by
the Selling Agent. Notwithstanding anything to the contrary herein, this
Agreement shall automatically terminate on August 31, 2009.

10.
Indemnification and Contribution.

(a)
The Company agrees to indemnify and hold harmless the Selling Agent, its
officers, directors, partners, employees, agents, and counsel, and each person,
if any, who controls the Selling Agent within the meaning of Section 15 of the
Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (the
Exchange Act), against any and all loss, liability, claim, damage, and
expense whatsoever (which shall include, for all purposes of this Section 10,
but not be limited to, attorneys fees and any and all expense whatsoever
incurred in investigating, preparing, or defending against any litigation,
commenced or threatened, or any claim whatsoever and any and all amounts paid
in settlement of any claim or litigation) as and when incurred arising out of,
based upon, or in connection with (i) any untrue statement or alleged untrue
statement of a material fact contained in the Documents, or any omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, unless such statement
or omission was made in reliance upon and in conformity with written
information furnished to the Company as stated in Section 10(b) with respect to
the Selling Agent expressly for inclusion in the Documents or (ii) any breach
of any representation, warranty, covenant, or agreement of the Company
contained in this Agreement. The foregoing agreement to indemnify shall be in
addition to any liability the Company may otherwise have, including liabilities
arising under this Agreement.

If
any action is brought against the Selling Agent or any of its officers,
directors, partners, employees, agent, or counsel, or any controlling persons
of the Selling Agent (an indemnified party), in respect of which indemnify
may be sought against the Company pursuant to the foregoing paragraph, such
indemnified party or parties shall promptly notify the Company (the
indemnifying party) in writing of the institution of such action (but the
failure so to notify shall not relieve the indemnifying party from any
liability it may have other than pursuant to this Section 10(a)) and the
indemnifying party shall promptly assume the defense of such action, including
the employment of counsel (reasonably satisfactory to such indemnified party or
parties) and payment of expenses. Such indemnified party shall have the right
to employ its own counsel in any such case, but the fees and expense of such
counsel shall be at the expense of such indemnified party unless the employment
of such counsel shall have been authorized in writing by the indemnifying party
in connection with the defense of such action or the indemnifying party shall
not have promptly employed counsel satisfactory to such indemnified party or
parties to have charge of the defense of such action or such indemnified party
or parties shall have reasonably concluded that there may be one or more legal
defenses available to it or them or to other indemnified parties which are
different from or additional to those available to one or more of the
indemnifying parties, in any of which events such reasonable fees and expenses
of one such counsel shall be borne by the indemnifying party and the
indemnifying party shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties. Anything in this
paragraph to the contrary notwithstanding, the indemnifying party shall not be
liable for any settlement of any such

5

---



claim or action effected without its written consent.
The Company agrees promptly to notify the Selling Agent of the commencement of
any litigation or proceedings against the Company or any of its officers or
directors in connection with the sale of the Securities, the Documents, or any
application.

(b)
The Selling Agent agrees to indemnify and hold harmless the Company, its
officers, directors, employees, agents, and counsel, and each other person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, to the same extent as the foregoing
indemnity from the Company to the Selling Agent in Section 10(a), with respect
to any and all loss, liability, claim, damage, and expense whatsoever (which
shall include, for all purposes of this Section 10, but not be limited to,
attorneys fees and any and all expense whatsoever incurred in investigating,
preparing, or defending against any litigation, commenced or threatened, or any
claim whatsoever and any and all amounts paid in settlement of any claim or
litigation) as and when incurred arising out of, based upon, or in connection
with (i) statements or omissions, if any, made in the Documents in reliance
upon and in conformity with written information furnished to the Company with
respect to the Selling Agent expressly for inclusion in the Documents, and (ii)
or any breach of any representation, warranty, covenant or agreement of the
Selling Agent contained in this Agreement. If any action shall be brought
against the Company or any other person so indemnified based on the Documents
and in respect of which indemnity may be sought against the Selling Agent
pursuant to this Section, the Selling Agent shall have the rights and duties
given to the indemnifying party, and the Company and each other person so
indemnified shall have the rights and duties given to the indemnified parties,
by the provisions of Section 10(a) hereof.

(c)
To provide for just and equitable contribution, if (i) an indemnified party
makes a claim for indemnification pursuant to Section 10(a) or 10(b) hereof but
it is found in a final judicial determination, not subject to further appeal,
that such indemnification may not be enforced in such case, even though this
Agreement expressly provides for indemnification in such case, or (ii) any
indemnified or indemnifying party seeks contribution under the Act, the
Exchange Act, or otherwise, then the Company (including for this purpose any
contribution made by or on behalf of any officer, director, employee, agent, or
counsel of the Company, or any controlling person of the Company), on the one
hand, and the Selling Agent (including for this purpose any contribution by or
on behalf of an indemnified party), on the other hand, shall contribute to the
losses, liabilities, claims, damages, and expenses whatsoever to which any of
them may be subject, in such proportions as are appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Selling
Agent, on the other hand; provided, however, that if applicable law does not
permit such allocation, then other relevant equitable considerations such as
the relative fault of the Company and the Selling Agent in connection with the
facts which resulted in such losses, liabilities, claims, damages, and expenses
shall also be considered. The relative benefits received by the Company, on the
one hand, and the Selling Agent, on the other hand, shall be deemed to be in
the same proportion as (x) the total proceeds from the Offering (net of
compensation payable to the Placement Agent pursuant to Section 5(a) hereof but
before deducting expenses) received by the Company, and (y) the compensation received
by the Selling Agent pursuant to Section 5(a) hereof.

The
relative fault, in the case of an untrue statement, alleged untrue statement,
omission, or alleged omission, shall be determined by, among other things,
whether such statement, alleged statement, omission, or alleged omission
relates to information supplied by the Company or by the Selling Agent, and the
parties relative intent, knowledge, access to information, and opportunity to
correct or prevent such statement, alleged statement, omission, or alleged
omission. The Company and the Selling Agent agree that it would be unjust and
inequitable if the respective obligations of the Company and the Selling Agent
for contribution were determined by pro rata or per capita allocation of the
aggregate losses, liabilities, claims, damages, and expenses or by any other
method of allocation that

6

---



does not reflect the equitable considerations referred
to in this Section 10(c). In no case shall the Selling Agent by responsible for
a portion of the contribution obligation in excess of the compensation received
by it pursuant to Section 5(a) hereof. No person guilty of a fraudulent
misrepresentation shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation. For purposes of this Section
10(c), each person, if any, who controls the Selling Agent within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act and each officer,
director, partners, employee, agent, and counsel of the Selling Agent, shall
have the same rights to contribution as the Selling Agent, and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and each officer, director, employee, agent,
and counsel of the Company, shall have the same rights to contribution as the
Company, subject in each case to the provisions of this Section 10(c). Anything
in this Section 10(c) to the contrary notwithstanding, no party shall be liable
for contribution with respect to the settlement of any claim or action effected
without its written consent.

11.
Non-Solicitation.

The
Company agrees that, for a period of 12 months from the date hereof, it shall
not solicit any offer to buy from or offer to sell to any Prospective Investor
set forth on Exhibit A attached hereto, directly or indirectly, any securities
of the Company or of any other entity, or provide the name of any such person
to any other securities broker or dealer or selling agent. In the event that
during the Non-Solicitation Period, the Company or any of its affiliates,
directly or indirectly, solicits, offers to buy from or offers to sell to any
such Prospective Investor set forth on Exhibit A any such securities, or
provides the name of any such person set forth on Exhibit A to any other
securities broker or dealer or selling agent, and such person purchases such
securities or purchases securities from any other securities broker or dealer
or selling agent, the Company shall pay to the Selling Agent an amount equal to
10% of the aggregate purchase price of the securities so purchased by such
person and the Company shall grant the Selling Agent (or its assigns) 5 year
warrants to purchase a number of shares of Common Stock equal to 20% of the
shares of Common Stock (or shares of Common Stock underlying any convertible
securities) sold, with an exercise price equal to the price of the securities
sold to the Prospective Investor set forth on Exhibit A. Upon receipt of
written request by the Selling Agent, the Company shall promptly deliver to the
Selling Agent the names of any investors in any offering that the Company
completes within 12 months from the date hereof. However, the compensation
entitled to GSS pursuant to the exercise of the Class B Warrants shall be valid
throughout the term of the Class B Warrant. This section shall survive any
termination.

12.
Representations and Agreements to Survive Delivery.

All
representations, warranties, covenants, and agreements contained in this
Agreement shall be deemed to be representations, warranties, covenants, and
agreements at the Closing Date and, such representations, warranties,
covenants, and agreements, including the indemnification and contribution
agreements contained in Section 10, shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of the Selling
Agent or any indemnified person, or by or on behalf of the Company or any
person or entity which is entitled to be indemnified under Section 10(b), and
shall survive termination of this Agreement or the issuance, sale, and delivery
of the Securities. In addition, notwithstanding any election hereunder or any
termination of this Agreement, and whether or not the terms of this Agreement
are otherwise carried out, the provisions of Sections 5 and 10 shall survive
termination of this Agreement and shall not be affected in any way by such
election or termination or failure to carry out the terms of this Agreement or
any part thereof.
