COMMON SHAREHOLDER PIGGYBACK REGISTRATION RIGHTS AGREEMENT 
  

 
 This Common Shareholder Piggyback
Registration Rights Agreement (“Agreement”) is made and entered into as of July 15, 2016 by and among One Stop Systems, Inc., a California corporation (“Company”) and the holders of the Company’s common
stock (“Common Stock”) listed on Exhibit A hereto. The holders of Common Stock will be referred to herein as “Common Shareholders” and each individually as a “Common Shareholder.” 

RECITALS 
 WHEREAS, this
Agreement is being executed and delivered pursuant to the Merger Agreement and Plan of Reorganization dated July 6, 2016 (“Merger Agreement”) by and among the Company, as buyer; Mission Technology Group, Inc., a California
corporation, as target, and Randy Jones, target shareholder. 
 WHEREAS, subject to the terms and conditions of the Merger Agreement, the
Company has agreed to grant Common Shareholders the piggyback registration rights set forth in this Agreement. 
 NOW, THEREFORE, in
consideration of the foregoing recitals and the mutual promises hereinafter set forth, the parties hereto agree as follows: 
 AGREEMENT

 1. REGISTRATION RIGHTS. 

1.1 Definitions. For purposes of Agreement: 

Registration. “Register,” “registered,” and
“registration” refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act of 1933, as amended (“Securities Act”), and
the declaration or ordering of effectiveness of such registration statement. 
 Registrable Securities. “Registrable
Securities” means: (a) any and all shares of the Company’s Common Stock and (b) any shares of Common Stock issued as (or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to, in exchange for or in replacement of, all such shares of Common Stock described in clause (a); excluding in all cases, however, any Registrable Securities sold by a
person in a transaction in which rights under this Section 1 are not assigned in accordance with this Agreement or any Registrable Securities sold to the public or sold pursuant to Rule 144 promulgated under the Securities Act
(“Excluded Shares”). 
 Registrable Securities Then Outstanding. “Registrable Securities
then Outstanding” will mean the number of shares of Common Stock which are Registrable Securities and (a) are then 








 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 issued and outstanding or (b) are then issuable pursuant to the exercise or conversion of then
outstanding and then exercisable options, warrants or convertible securities. 
 Holder. “Holder”
or “Holders” means any person or persons owning of record Registrable Securities that have not been sold to the public or pursuant to Rule 144 promulgated under the Securities Act or
any assignee of record of such Registrable Securities to whom rights under this Section 1 have been duly assigned in accordance with this Agreement; provided, however, the Company will in no event be obligated to register Common Stock. 

SEC. “SEC” means the United States Securities and Exchange Commission. 

1.2 Piggyback Registrations. 

(a) Piggyback Registrations. The Company will notify all Holders of Registrable Securities in writing at least thirty (30) days
prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to any demand or Form S-3 registration of the Company’s preferred shareholders or to any employee benefit plan or a corporate reorganization) and
will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the
Registrable Securities held by such Holder will, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice will inform the Company of the number of Registrable
Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder will nevertheless continue to
have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein.

 (b) Underwriting. If a registration statement under which the Company gives notice under this Section 1.2 is for an
underwritten offering, then the Company will so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable Securities to be included in a registration pursuant to this Section 1.2 will be
conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities
through such underwriting will enter into an underwriting agreement in customary form with the managing underwriter or underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Agreement, if the managing
underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares (including Registrable Securities) from the registration and the
underwriting, and the number of shares that may be included in the registration and the underwriting will be allocated, first, to the Company, and second, to each of the Holders requesting inclusion of their Registrable Securities in such
registration statement on a pro rata basis based on the total number of Registrable Securities then held by each such Holder. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by 

  
 2 









 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 written notice to the Company and the underwriter, delivered at least ten (10) business days prior to
the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting will be excluded and withdrawn from the registration. For any Holder which is a partnership or corporation, the partners,
retired partners and shareholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons will be deemed to be a single “Holder,” and any
pro rata reduction with respect to such “Holder” will be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 

(c) Expenses. All expenses incurred in connection with a registration pursuant to this Section 1.2 (excluding underwriters’
and brokers’ discounts and commissions), including, without limitation all federal and “blue sky” registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one (1) counsel for the selling Holder or Holders will be borne by the Company. 
 1.3
Obligations of the Company. Whenever required to effect the registration of any Registrable Securities under this Agreement, the Company will, as expeditiously as reasonably possible: 

(a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to ninety (90) days; 

(b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with
such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement; 

(c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of
the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration; 

(d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as will be reasonably requested by the Holders, provided the Company will not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in
any such states or jurisdictions; 
 (e) In the event of any underwritten public offering, enter into and perform its obligations under an
underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering (it being understood and agreed, as a condition to the Company’s obligations under this clause (e), each Holder participating in such
underwriting will also enter into and perform its obligations under such an agreement); 

  
 3 









 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 (f) Notify each Holder of Registrable Securities covered by such registration statement at
any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; and 

(g) Furnish, at the request of any Holder requesting registration of Registrable Securities, on the date such Registrable Securities are
delivered to the underwriters for sale, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date the registration statement with respect to such securities becomes effective,
(i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and reasonably satisfactory
to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a “comfort” letter dated as of such date, from the
independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering and reasonably satisfactory to a majority in
interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. 

1.4 Furnish Information. It will be a condition precedent to the obligations of the Company to take any action pursuant to
Section 1.2 hereof that the selling Holders will furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as will be required to timely
effect the registration of their Registrable Securities. 
 1.5 Delay of Registration. No Holder will have any right to obtain
or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1. 

1.6 Indemnification. In the event any Registrable Securities are included in a registration statement under
Section 1.2 hereof: 
 (a) By the Company. To the extent permitted by law, the Company will indemnify and hold harmless each
Holder, the partners, officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the
Securities Exchange Act of 1934, as amended, (“Exchange Act”), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): 

(i) Any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or supplements thereto; 

  
 4 









 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 (ii) The omission or alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading; or 
 (iii) Any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any federal or state securities law in connection with the offering covered by such
registration statement; 
 and the Company will reimburse each such Holder, partner, officer or director, underwriter or controlling person for any legal or
other expenses reasonably incurred by them, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, the indemnity agreement contained in this Subsection 1.6(a) will not apply
to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent will not be unreasonably withheld), nor will the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such
registration by such Holder, partner, officer, director, underwriter or controlling person of such Holder. 
 (b) By Selling Holders.
To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the registration statement, each person, if any, who controls the Company within the
meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, partner or director, officer or
controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based
upon any Violation, in each case to the extent (and only to the extent) such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such
Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, director or controlling person of such other Holder in connection
with investigating or defending any such loss, claim, damage, liability or action; provided, however, the indemnity agreement contained in this Subsection 1.6(b) will not apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the consent of the Holder, which consent will not be unreasonably withheld; and provided further, the total amounts payable in indemnity by a Holder under this Subsection 1.6(b) in respect of any
Violation will not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises. 
 (c)
Notice. Promptly after receipt by an indemnified party under this Section 1.6 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made
against any indemnifying party under this Section 1.6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party will have the right to participate in, and, to the extent the 

  
 5 









 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with counsel mutually satisfactory to the parties; provided, however, an indemnified party will have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such
indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The
failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, will relieve such indemnifying party of any liability to the
indemnified party under this Section 1.6, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability it may have to any indemnified party otherwise than under this Section 1.6. 

(d) Defect Eliminated in Final Prospectus. The foregoing indemnity agreements of the Company and Holders are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement in question becomes effective or the amended prospectus
filed with the SEC pursuant to SEC Rule 424(b) (“Final Prospectus”), such indemnity agreement will not inure to the benefit of any person if a copy of the Final Prospectus (i) was furnished to the indemnified party and
(ii) was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act. 

(e) Contribution. In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in
which either (i) any Holder exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 1.6 but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact this Section 1.6
provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling Holder or any such controlling person in circumstances for which indemnification is provided under this
Section 1.6; then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so such Holder is
responsible for the portion represented by the percentage that the public offering price of its Registrable Securities offered by and sold under the registration statement bears to the public offering price of all securities offered by and sold
under such registration statement, and the Company and other selling Holders are responsible for the remaining portion; provided, however, in any such case, (A) no such Holder will be required to contribute any amount in excess of the public
offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 
 (f)
Survival. The obligations of the Company and Holders under this Section 1.6 will survive the completion of any offering of Registrable Securities in a registration statement, and otherwise.

 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 1.7 “Market Stand-Off” Agreement.

 (a) Each Holder hereby agrees it will not, to the extent requested by the Company or an underwriter of securities of the Company, sell
or otherwise transfer or dispose of or engage in any other transaction regarding any Registrable Securities or other shares of stock of the Company then owned by such Holder (other than to donees or partners of the Holder who agree to be similarly
bound) for up to one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act; provided, however, all executive officers and directors of the Company then holding Common
Stock of the Company enter into similar agreements. 
 (b) In order to enforce the foregoing covenant, (i) the Company will have the
right to place restrictive legends on the certificates representing the shares subject to this Section 1.7 and to impose stop transfer instructions with respect to the Registrable Securities and such other shares of stock of each Holder (and
the shares or securities of every other person subject to the foregoing restriction) until the end of such period and (ii) the Holder agrees to execute the form of agreement requested by the Company and/or underwriter. 

1.8 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC which may
at any time permit the sale of the Registrable Securities to the public without registration, after such time as a public market exists for the Common Stock of the Company, the Company agrees to: 

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 

(b) Use its best efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities
Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 
 (c) As long as a Holder owns any
Registrable Securities, to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the effective date of the
first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to the reporting requirements of the Exchange Act), a
copy of the most recent annual or quarterly report of the Company and such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such
securities without registration (at any time after the Company has become subject to the reporting requirements of the Exchange Act). 

1.9 Termination of the Company’s Obligations. The Company will have no obligations pursuant to Section 1.2 with
respect to: (a) any request or requests for registration made by any Holder on a date more than two (2) years after the closing date of the first firmly underwritten public offering of Common Stock of the Company pursuant to a Registration


  
 7 









 COMMON SHAREHOLDER PIGGYBACK REGISTRATION
RIGHTS AGREEMENT 
  
  

 Statement filed with, and declared effective by, the SEC under the Securities Act, on the terms and
conditions approved by the Company’s board of directors (an “Initial Public Offering”) or (b) any Registrable Securities proposed to be sold by a Holder in a registration pursuant to Section 1.2 if, in the opinion of
counsel to the Company, all such Registrable Securities proposed to be sold by a Holder may be sold in a three-month period without registration under the Securities Act pursuant to Rule 144 under the Securities Act. 

1.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company will not,
without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company that provides such holder or prospective
holder with registration rights superior to the registration rights provided to the Common Shareholders pursuant to this Section 1. 
 2.
ASSIGNMENT AND AMENDMENT. 
 2.1 Assignment.
Notwithstanding anything herein to the contrary, the registration rights of a Holder under Section 1 may be assigned only to (a) a party who acquires at least two hundred fifty thousand (250,000) shares of Registrable
Securities or (b)(i) a shareholder, partner, member, or beneficiary of such Holder; (ii) a spouse, child, parent or beneficiary of the estate of such Holder or (iii) a trust for the benefit of the persons set forth in (i) or (ii);
provided, however, no party may be assigned any of the foregoing rights unless the Company is given written notice by the assigning party at the time of such assignment stating the name, address and tax identification number of the assignee and
identifying the securities of the Company as to which the rights in question are being assigned; and provided further any such assignee will receive such assigned rights subject to all the terms and conditions of this Agreement, including without
limitation the provisions of this Section 2. 
 2.2 Amendment of Rights. Subject to Section 2.3, any provision of
this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Common Shareholders (and/or any
of their permitted successors or assigns) holding shares of Registrable Securities representing and/or convertible into a majority of all Registrable Securities. Any amendment or waiver effected in accordance with this Section 2.2 will be
binding upon each Common Shareholder, each Holder, each permitted successor or assignee of such Common Shareholder or Holder and the Company. 

2.3 New Common Shareholders. Notwithstanding anything herein to the contrary, if additional parties purchase shares of
Common Stock from the Company (each such person or entity, a “New Common Shareholder”), then each such New Common Shareholder will become a party to this Agreement as a “Common Shareholder” hereunder, without the
need for any consent, approval or signature of any Common Shareholder when such New Common Shareholder has both: (a) purchased shares of Common Stock and paid the Company all consideration payable for such shares and (b) executed one or more
counterpart signature pages to this Agreement as a “Common Shareholder,” with the Company’s consent.
