                                  INTRODUCTION



         This  statement  on  Schedule  13D (the  "Statement")  constitutes  the
initial  filing  by,  MidMark  Capital,  L.P.,  a Delaware  limited  partnership
("MidMark") with respect to the beneficial  ownership of shares of common stock,
par value $.005 per share, of Vertex Industries, Inc., a New Jersey corporation.

         This Statement is being filed by MidMark.



ITEM 1.  SECURITY AND ISSUER

         The title of the class of equity  securities to which this Statement on
Schedule 13D relates is the common stock, par value $.005 per share (the "Common
Stock"),  of Vertex Industries,  Inc., a New Jersey corporation (the "Company").
The address of the Company's principal executive office is 23 Carol Street, P.O.
Box 996, Clifton, New Jersey 07014.



ITEM 2.  IDENTITY AND BACKGROUND

         This  Statement  is being filed by MidMark  (the  "Reporting  Person").
MidMark is a small business investment company. It's principal executive offices
are located at 466 Southern Boulevard,  Chatham,  New Jersey 07928.  Information
regarding  the  directors,  executive  officers  and or  control  persons of the
Reporting Person is set forth on Schedule I attached  hereto,  which Schedule is
hereby incorporated by reference.

         During  the last  five  years,  the  Reporting  Person  or, to the best
knowledge of the Reporting  Person,  any person named in Schedule I has not been
(a) convicted in a criminal proceeding  (excluding traffic violations or similar
misdemeanors)   or  (b)  a  party  to  a  civil  proceeding  of  a  judicial  or
administrative body of competent jurisdiction and as a result of such proceeding
was or is  subject  to a  judgment,  decree  or  final  order  enjoining  future
violations  of, or prohibiting  or mandating  activities  subject to, Federal or
State securities laws or finding any violation with respect to such laws.



ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION


         The  5,000,000  shares  of  Common  Stock  beneficially  owned  by  the
Reporting Person were acquired pursuant to a Subscription Agreement, dated as of
June 21, 1999 as amended on August 23, 1999 and September 13, 1999, by and among
Edwardstone & Company,  Incorporated,  a Delaware  corporation  ("Edwardstone"),
MidMark  and  the  Company  (as  amended,  the  "Subscription  Agreement";  such
Subscription  Agreement  is attached as Exhibits 1, 2 and 3, which  Exhibits are
hereby  incorporated  by reference).  Such shares were purchased by MidMark with
the working capital of MidMark at an aggregate cost of $5,000,000.  To raise the
working capital necessary to fund the acquisition, MidMark called in commitments
from its limited partners, including the Small Business Administration, which is
a preferred limited partner in MidMark.

ITEM 4.  PURPOSE OF TRANSACTION.

         The  acquisition  of  the  5,000,000  shares  of  Common  Stock  by the
Reporting  Person  was made in an  effort to gain,  along  with  Edwardstone,  a
controlling  ownership  interest in the  Company.  Pursuant to the  Subscription
Agreement,  MidMark purchased  5,000,000 shares of Common Stock from the Company
and Edwardstone purchased 5,449,642 shares of Common Stock from the Company.

         As a condition to  MidMark's  and  Edwardstone's  purchase of shares of
Common Stock,  MidMark,  Edwardstone and the Company entered into a Stockholders
Agreement,  dated as of September 15, 1999 (the "Stockholders  Agreement";  such
Stockholders  Agreement  is  attached  as  Exhibit  4,  which  Exhibit is hereby
incorporated by reference),  containing certain terms and conditions  concerning
the acquisition and disposition of such shares of Common Stock and the corporate
governance of the Company. Other than the Stockholders  Agreement,  there are no
agreements or understandings between MidMark and Edwardstone with respect to the
Company or its outstanding securities,  and MidMark does not believe that it and
Edwardstone  constitute  a group  within the meaning of Section  13(d)(3) of the
Act.

 ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

                  (a) MidMark beneficially owns 5,000,000 shares of Common
Stock, 29.6% of the Common Stock of the Company.

                  (b) MidMark has the sole power to vote,  direct the voting of,
dispose of and direct the disposition of 5,000,000 shares of Common Stock of the
Company.

                  (c) Except as described in  paragraph  (a) above,  neither the
Reporting Person nor, to the best knowledge of the Reporting Person,  any of the
persons referred to in Schedule I attached hereto, has effected any transactions
in the Common Stock during the past 60 days.

                  (d) The Reporting  Person has the sole right to receive or the
power to direct the receipt of dividends from, or the proceeds from the sale of,
the Common Stock owned by it.

                  (e)      Not applicable.



ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

         Except as described  herein,  the Reporting Person nor any other person
referred  to in  Schedule I attached  hereto  has any  contracts,  arrangements,
understandings  or  relationships  (legal or  otherwise)  with any  person  with
respect  to any  securities  of the  Company,  including,  but not  limited  to,
transfer or voting of any of the securities, finder's fees, joint ventures, loan
or option  arrangements,  puts or calls,  guarantees  of  profits,  division  of

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company represents and warrants to each Purchaser as

its Subsidiaries is a corporation duly incorporated, validly existing and in
good standing under the Laws of its jurisdiction of incorporation, and has all
requisite corporate power and authority to conduct its business as and to the
extent now conducted and to own, use and lease its Assets and Properties, except
for such failures to be so incorporated, existing and in good standing or to
have such power and authority which, individually or in the aggregate, are not
having and could not be reasonably expected to have a Material Adverse Effect on
the Company and its Subsidiaries taken as a whole. Each of the Company and its
Subsidiaries is duly qualified, licensed or admitted to do business and is in
good standing in New Jersey, which is the only jurisdiction in which the
ownership, use or leasing of its Assets and Properties, or the conduct or nature
of its business, makes such qualification, licensing or admission necessary.
Section 2.01 of the Company Disclosure Schedule sets forth (i) the name and
jurisdiction of incorporation of each Subsidiary of the Company, (ii) its


                                       2
<PAGE>

authorized capital stock, (iii) the number of issued and outstanding shares of
capital stock and (iv) the record owners of such shares. Except for interests in
the Subsidiaries of the Company and as disclosed in Section 2.01 of the Company
Disclosure Schedule, the Company does not directly or indirectly own any equity
or similar interest in, or any interest convertible into or exchangeable or
exercisable for, any equity or similar interest in, any corporation,
partnership, joint venture or other business association or entity. The Company
has previously delivered to each Purchaser correct and complete copies of the
certificate or articles of incorporation and bylaws (or other comparable charter
documents) of the Company and each of its Subsidiaries.

                  2.02 Authority. The Company has the requisite corporate power
and authority to execute and deliver this Agreement and the Operative Agreements
to which it is a party and to perform its obligations hereunder and thereunder
and to consummate the transactions contemplated hereby and thereby. The
execution, delivery and performance by the Company of this Agreement and the
Operative Agreements to which it is a party and the consummation by the Company
of the transactions contemplated hereby and thereby have been duly and validly
approved by the Board of Directors of the Company. In addition, the Board of
Directors of the Company has adopted a resolution substantially in the following
form:

                  "RESOLVED, that the Company be, and it hereby is, authorized
                  to engage, from time to time, in any "business combination"
                  (as defined in Section 14A:10A-3 of the New Jersey Business
                  Corporation Act) with or otherwise involving or affecting
                  Edwardstone, MidMark and/or their respective Affiliates,
                  including, without limitation, repurchases by the Company of
                  shares of its common stock from such Person(s), loan
                  transactions, and transactions that may involve the sale or
                  issuance by the Company of its assets or voting securities (or
                  securities convertible into, or exchangeable for, its voting
                  securities), on such terms and conditions as may be agreed
                  upon by the parties thereto at the time of such
                  transaction(s), the intent of this resolution being to
                  constitute advance approval of such transaction(s) as required
                  by Section 14A:10A-4 of the New Jersey Business Corporation
                  Act."

are necessary to authorize the execution, delivery and performance by the
Company of this Agreement and the Operative Agreements to which it is a party

thereby. This Agreement has been duly and validly executed and delivered by the

compliance with applicable permits or give rise to any common Law or statutory
Liability or otherwise form the basis of any claim, action or proceeding with

<PAGE>

Schedule contains an accurate and complete description of all such Intellectual
Property used or proposed to be used by the Company or any of its Subsidiaries
and indicates whether such Intellectual Property is owned or licensed by the
Company or its Subsidiaries. To the Company's Knowledge, the Company or its
Subsidiaries has the sole and exclusive right to use such Intellectual Property
and the consummation of the transactions contemplated hereby will not alter or
impair any such rights; no claims have been asserted by any Person to the use of
any such Intellectual Property or challenging or questioning the validity or
effectiveness of any license or agreement relating to such Intellectual
Property, and there is no valid basis for any such claim; and the use of such
Intellectual Property by the Company or any of its Subsidiaries does not
infringe on the rights of any Person. The Company or its Subsidiaries has full
right, title and interest in and to, pursuant to existing agreements and/or
applicable Law, all material Intellectual Property developed by or on behalf of
any present or past employee of the Company or any of its Subsidiaries while so
employed, and all such Intellectual Property now used or proposed to be used by
the Company or its Subsidiaries is the property of the Company and its
Subsidiaries.

Company SEC Reports filed prior to the date of this Agreement or in Section 2.17

         2.01  Composition  of Board of Directors.  (a) Effective at the Closing

the purpose of voting on the election of directors, three individuals designated

Securities  representing  less than 5% of the  Voting  Power of all  Outstanding
Voting  Securities,  if any director  designated  by such Investor in accordance
with this Section 2.01 shall decline or be unable to serve for any other reason,
the Board of Directors shall promptly upon the request of such Investor nominate

<PAGE>

of  this  Section  3.01(c).  Each  certificate  representing  Equity  Securities
beneficially  owned by any  Investor  shall be  imprinted  with a legend  in the
following  form until such time (subject to the provisions of the final sentence
of this Section  3.01(c)) as all  restrictions on the Disposition of such Equity
Securities hereunder are terminated:

         "THESE  SHARES HAVE NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF
         1933, AS AMENDED,  OR THE  SECURITIES  LAWS OF ANY STATE AND MAY NOT BE
         SOLD, TRANSFERRED,  OR OTHERWISE DISPOSED OF UNLESS THEY ARE REGISTERED
         OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE.  SUCH SHARES MAY
         ONLY BE  TRANSFERRED  PURSUANT  TO THE  PROVISIONS  OF ARTICLE III OF A
         CERTAIN STOCKHOLDERS AGREEMENT DATED AS OF _____ __, 1999, BY AND AMONG
         VERTEX  INDUSTRIES,  INC.,  A NEW  JERSEY  CORPORATION,  EDWARDSTONE  &
         COMPANY,  INCORPORATED,  A DELAWARE  CORPORATION,  AND MIDMARK CAPITAL,
         L.P., A DELAWARE LIMITED PARTNERSHIP,  COPIES OF WHICH AGREEMENT ARE ON
         FILE AT THE PRINCIPAL OFFICE OF THE COMPANY."

The Company  shall not (i) give effect on its books to an attempted  Disposition
of any Equity  Securities  which shall have been Disposed of in violation of any
provision  of this  Stockholders  Agreement,  or (ii) treat any  transferee  who
obtains any Equity Securities in violation of any provision of this Stockholders
Agreement  as the  owner of such  Equity  Securities  or accord  any  transferee
thereof  the right to vote or to receive  dividends  in  respect of such  Equity
Securities.  The Company  will issue new  certificates  not  imprinted  with the
foregoing  legend  to  any  holder  of  Equity  Securities  not  subject  to the
restrictions on Disposition contained in this Stockholders Agreement;  provided,
that the Company may require an opinion of counsel reasonably satisfactory to it
to the effect that no legend is required under the Securities Act and applicable
state securities Laws.


         3.02  Tag-Along  Sale.  (a)  Tag-Along  Obligations.  If at any time an
Investor or any Affiliate of an Investor  ("Tag-Along  Seller") shall, in one or
in a series of  transactions,  enter into an agreement  to effect,  or effect or
propose to effect,  a Disposition  to any transferee (a "Tag-Along  Sale"),  the
other  Investor (the  "Tag-Along  Investor")  shall have the right,  but not the
obligation, to participate in such Tag-Along Sale by selling up to the number of
shares of VTX Common Stock into which the Equity Securities  beneficially  owned
by the Tag-Along Investor are convertible and shares of VTX Common


                                       7
<PAGE>

Stock  owned by such  Tag-Along  Investor  equal to the product of (i) the total
number  of  shares  of VTX  Common  Stock  proposed  to be sold in the  proposed
Tag-Along Sale multiplied by (ii) a fraction, the numerator of which is equal to
the  number of shares of VTX  Common  Stock  into  which the  Equity  Securities
beneficially  owned by the Tag-Along  Investor are convertible and shares of VTX
Common Stock owned by such Tag-Along Investor together with the number of shares
of VTX Common  Stock  owned by any holder  thereof  who is entitled to so called
"Tag along"  rights and elects to exercise  such rights in  connection  with the
Tag-Along  Sale, in each case  immediately  prior to the Tag-Along Sale, and the
denominator  of which is equal to (A) the number of shares of VTX  Common  Stock
owned by the Tag-Along Seller  immediately  prior to the Tag-Along Sale plus (B)
the number of shares (on an aggregate  basis) of VTX Common Stock into which the
Equity Securities  beneficially  owned by the Tag-Along Investor are convertible
and shares of VTX Common Stock owned by such  Tag-Along  Investor  together with
the number of shares of VTX Common  Stock  owned by any  holder  thereof  who is
entitled to so called "Tag along"  rights and elects to exercise  such rights in
connection  with the Tag  Along  Sale,  in each  case  immediately  prior to the
Tag-Along  Sale.  Any such sales by the Tag-Along  Investor shall be on the same
terms and  conditions as the proposed  Tag-Along  Sale by the Tag-Along  Seller,
except the Tag-Along Investor shall not be required to make any  representations
or warranties except as to (x) its title to the shares of VTX Common Stock to be
sold by it, (y) such  holder's  power and  authority to effect such transfer and
(z) such matters  pertaining to compliance with securities law as the transferee
may reasonably require.

         (b) Procedures.  If a Tag-Along  Seller is participating in a Tag-Along
Sale, at least 30 days before the proposed date  thereof,  the Tag-Along  Seller
shall  provide the other  Investor and the Company  with written  notice of such
Tag-Along Sale setting forth in reasonable detail the consideration per share to
be paid by the  transferee  and the other terms and  conditions of the Tag-Along
Sale. If the other Investor wishes to participate in the Tag-Along Sale, then it
shall provide written notice to such Tag-Along  Seller and to the Company within
15 days of the date the notice  specified in the preceding  sentence is received
by such holder.  Such notice shall set forth the number (on an aggregate  basis)
of then exercisable Convertible Securities, Rights to Purchase Voting Securities
and shares of VTX Common Stock,  if any, such Investor  elects to include in the
Tag-Along  Sale. If such notice is not received from the other  Investor  within
the 15 day period specified


                                       8
<PAGE>

above, the Tag-Along  Seller shall have the right to sell or otherwise  transfer
the  shares  of  VTX  Common  Stock  to  the  proposed  transferee  without  any
participation  by the other  Investor,  but only (i) on the terms and conditions
stated in the  notice,  and (ii) if the sale or  transfer  of such shares of VTX
Common Stock is consummated  not later than 60 days after the end of such 15 day
period  specified  above.  The  provisions  of this  Section  3.02  shall  apply
regardless of whether the consideration  received in the Tag-Along Sale is cash,
debt, equity securities, property-in-kind, or any combination thereof.

discussions and agreements  among the parties hereto with respect to the subject
matter  hereof,  and contains,  together with the  Subscription  Agreement,  the
Registration Rights Agreement, and the other Operative Agreements (as defined in

with respect to the subject matter hereof.


         7.06 No Third  Party  Beneficiary.  The  terms and  provisions  of this
Stockholders Agreement are intended solely for the benefit of each party hereto,
and it is not the  intention  of the parties to confer  third-party  beneficiary

         7.08 Specific  Performance;  Legal Fees. The parties  acknowledge  that

of this  Stockholders  Agreement and that in addition to money damages any party
may, in its sole  discretion,  apply to a court of  competent  jurisdiction  for
specific  performance for injunctive or such other relief as such court may deem
just and proper in order to enforce any such  provision or prevent any violation
hereof and, to the extent  permitted by  applicable  Law,  each party waives any
objection to the  imposition of such relief.  The parties  hereto agree that, in
the event that any party to this  Stockholders  Agreement  shall bring any legal
action or proceeding to enforce or to seek damages or other relief  arising from
an alleged breach of any term or provision of this Stockholders Agreement by the
other party,  the  prevailing  party in any such action or  proceeding  shall be
entitled to an award of, and the other party to such action or proceeding  shall
pay, the reasonable fees and expenses of legal counsel to the prevailing party.

Stockholders  Agreement will not be materially and adversely  affected  thereby,

will be construed  and  enforced as if such  illegal,  invalid or  unenforceable
provision had never  comprised a part hereof and (iii) the remaining  provisions

be  affected  by the  illegal,  invalid  or  unenforceable  provision  or by its
severance herefrom.

         7.12 Arbitration. The parties to this Stockholders Agreement agree that
any  disputes   arising  out  of,  or  in  connection   with,   the   execution,
interpretation,  performance or non-performance  of this Stockholders  Agreement

party if determined by the Board of  Arbitration  to be relevant to the dispute,
(b)  conducting   arbitration  hearings  to  the  greatest  extent  possible  on
successive  business  days and (c) using their best  efforts to observe the time
periods  established by the rules of the AAA or by the Board of Arbitration  for
the submission of evidence and briefs.  The decision of the Board of Arbitration
shall be final,  binding and not subject to further review,  and judgment on the
award of the Board of  Arbitration  may be entered in and  enforced by any court
having  jurisdiction  over the parties or their  assets.  Any costs  incurred in
conducting the arbitration shall be borne by the  non-prevailing  (as determined
by the Board of Arbitration) party.
